Oracle SQL Tutorial 33 - NUMBER Data Type
 
07:18
This video we are going to discuss the NUMBER data type. The Number data type is used to store integers, and real numbers. When you create a column as a NUMBER, you can store pretty huge or pretty small numbers in this column. Now there are two things you need to consider when working with numbers, and that is the precision as well as the how big the number is. For example, we can store the number 9.9. This has two significant digits. We could also store the number 9.9 X 10^4. In this situation, the number is much larger, but the number of significant digits is the same. 9.9 are the significant digits. When we expand this out we just have 99000, and the zeros are just used for size and are not considered "significant" in this situation. In fact, you get a max precision of 38, but a maximum value of 9.99 * 10^125. You can also use this data type to store very small numbers. Check the docs for the specifics on maximums and minimums. You can provide it with two pieces of information: Precision - The total number of digits. Scale - The number of digits to the right of the decimal. You do it in this format: NUMBER (precision, scale). The important thing to remember in this is that when you specify a precision, you will be limiting the max size of the numbers. The secret behind this data type is that it is actually stored in scientific notation. That is we store a number and then we can multiply it by 10 raised to some power. This allows us to store much larger numbers without taking up a ton of space. The oracle docs actually gives a formula that you can use to see how much storage is going to be required for a specific NUMBER data type. How much precision can be used? The acceptable range is 1-38. What about scale? The range is actually -84 to 127. I'll explain the scale in more detail in an upcoming video. That's because there is a lot of confusing things here…What does it mean for the scale to be negative? How can we have a scale that is bigger that the total number of digits available through the precision. That's a topic for another video. It's important to understand that when we increase our scale, we decrease the max size of the number. For example if we have a precision of 5 and a scale of 3, the highest number we can store is 99.999. This is in contrast to a precision of 5 and a scale of 2 which allows for up to 99.999. Either way you get 5 significant digits, but the numbers of digits to the left and right of the decimal change. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 24 - Important Data Types
 
06:09
In the upcoming videos we are going to discuss data types in depth, but I don't want to drown you in all of the details. Because of that, I'm giving you this video which is going to introduce you to the most important data types. Then, in the upcoming videos, I'll describe them in more depth. One of the data types we've already discussed in this video is NUMBER. This data type is used to, obviously, store a number. It can be used to store integers (whole numbers), or numbers with decimals. There are two other numeric data types you should know of. BINARY_FLOAT and BINARY_DOUBLE are both numeric data types that are known as floating point numbers. A floating point number is often used for large numbers that have decimal places where it is acceptable to not be completely precise. What I mean by this is that these numbers can only store numbers correctly up to a certain decimal point. If you need perfect precision, you will want to use the NUMBER data type. Now storing numbers is good sometimes, but occasionally you will want to store string data. String data can be any sequence of characters, including numbers. By telling the database that a column is a string data type, the database knows how to treat that column. There are four important string data types that you need to know about. The first two are CHAR and NCHAR. These data types are used to store a fixed-length string. So for example, you can say you want to store 12 characters. This means that every value for this column will be exactly 12 characters. If you insert less than 12 characters, the data will be padded with spaces. This means you will want to use one of these data types when every value in the column is the same length. What is the difference between CHAR and NCHAR? CHAR uses what is known as ASCII while NCHAR uses Unicode. The difference is what characters are allowed and how much space each character takes. ASCII takes up less space but only supports English, numbers, and some symbols. UNICODE allows you to store characters from multiple languages but takes up more space. Those were both fixed-length string. What if you want to store data that changes in length? That is where VARCHAR2 and NVARCHAR2 come in. When it comes to storing dates, the data types that are most important are DATE and TIMESTAMP. Date can be used to store dates and time. Timestamp is a data type that can be used to store an exact moment in time. Lastly, there are interval types. These store a date range. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

MySQL 31 - DECIMAL Data Type
 
02:20
The DECIMAL data type is similar to the INT data type in that when you use the number for math, it maintains precision. The difference though is obvious in the name. The DECIMAL data type allows for numbers after a decimal point (and before the decimal point). The DECIMAL data type allows us to store what is known as a fixed-point number. A fixed point number is a number that has a specific number of digits available to store numbers in. That means we can't do things like use a DECIMAL data type to store as many digits of PI as possible, because we can't store unlimited digits. We are limited to a certain number. There are two keywords you need to understand when you are working with the DECIMAL data type, precision and scale. Precision is the number of digits and scale is the number of those digits that will come after the radix. You are going to want to provide these numbers when you declare a column of this data type. For example, DECIMAL(5, 2) has a precision of 5 digits and a scale of 2 digits. That means we can store a maximum of two digits after the decimal and four digits total. This gives us a possible range from -999.99 to 999.99 The highest number of digits is 65, and the highest number of digits after the decimal is 30. This data type is also known as DEC, NUMERIC, and FIXED. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle CEIL Function
 
01:56
https://www.databasestar.com/oracle-ceil/ The Oracle CEIL function, short for “ceiling”, will return the smallest integer value greater than the specified number. In other words, it rounds up to the nearest whole number. It’s the opposite of the FLOOR function, which rounds down. The syntax of CEIL is: CEIL(number) The number parameter can be any numeric data type. The CEIL function will return a number in the same data type as the parameter. So, you can use CEIL with decimal numbers, which is actually where CEIL works best. You can use it with whole numbers too. It won’t show an error, it just might display the same value as provided (e.g. CEIL(8) would be 8). You can also use functions inside CEIL. For example, CEIL(SUM(salary)) will SUM all of the salary values, and then round them up to the nearest whole number. Like with all functions, the Oracle CEIL function can also use column aliases. So, instead of having your column labelled “CEIL(8.12)” or “CEIL(salary)”, you can label your column “salary_rounded” or something that makes more sense. The CEIL function is similar to the ROUND function. However, ROUND will round up or down, where CEIL will always round up. The TRUNC function will also do some kind of rounding, but it removes decimals from a number which may cause it to “round” down.

MySQL 32 - FLOAT and DOUBLE Data Types
 
06:23
FLOAT and DOUBLE data types are data types that can be used to store numbers that can include decimal numbers. They are specifically used to store estimates. What do I mean? I mean that the precision of a FLOAT or DOUBLE value can be lost when doing math. The data types are only capable of maintaining a certain level of precision. The level of precision is usually adequate for most mathematical operations. If you need to store exact data, you will want to look into using the INT or DECIMAL data type instead. The numbers stored in a FLOAT or DOUBLE column are called floating point numbers, we'll see why in just a moment. Why are they called floating point numbers? let's look at a number. 150. This number could be represented as 150, or it could be represented as 1.5 * 10^2, or 1.5e2. With floating point numbers, scientific notation is used. These numbers are called floating point numbers because the decimal can float to different spots as we change the exponent. This means that the data type needs to store the number, how many decimal the number needs moved, and a sign bit. The benefit of floating point numbers is that they allow us to store pretty huge numbers. The down side is that they are not storing values exactly because they are limited in size. This means that only a certain level of precision is to be expected from a floating point data type. If you remember from the video of DECIMAL, precision is the number of digits in a number. As long as the precision for one of these data types exceeds the need for your specific data, the data type can work fine. For example, if you are storing a number like 15 trillion, you don't have to worry as much with precision as your number does not contain a lot of digits. This number can be represented as 1.5 x 10^13. This is a lot different than trying to store 1.5534534534 x10^13. Now we know both of these data types do not maintain a high number of digits correctly, but what is the difference between FLOAT and DOUBLE. The difference is the amount of storage they take up. Float takes up 4 bytes while DOUBLE takes up 8. The benefit in DOUBLE is that because it has more room to store data, it has a higher level of precision and can store bigger numbers. Now, what level of precision can you expect from either of these? FLOAT around 7 and DOUBLE around 15. Now, these data types are obnoxious because the exact values depend on your operating system and in general these monsters cannot be trusted. Especially when you start doing math with different numbers. In general, it is recommended to use the DOUBLE data type to have a higher level of precision and calculations in MySQL are done with DOUBLE. Always remember… prepare for trouble, make it double. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle FLOOR Function
 
01:49
https://www.databasestar.com/oracle-ceil/ The Oracle FLOOR function will return the largest integer value less than the specified number. In other words, it rounds down to the nearest whole number. It’s the opposite of the CEIL function, which rounds up. The syntax of FLOOR is: FLOOR(number) The number parameter can be any numeric data type. The function will return a number in the same data type as the parameter. So, you can use FLOOR with decimal numbers, which is actually where FLOOR works best. You can use it with whole numbers too. It won’t show an error, it just might display the same value as provided (e.g. FLOOR(5) would be 5). You can also use functions inside FLOOR. For example, FLOOR(SUM(salary)) will SUM all of the salary values, and then round them down to the nearest whole number. Just like with all functions, the Oracle FLOOR function can also use column aliases.

Oracle UPPER Function
 
02:32
https://www.databasestar.com/oracle-upper-lower/ The Oracle UPPER function is used to convert a string to an uppercase value. It capitalises a string value. It’s useful for comparing text or string values that may have mixed case, such as user input or data from different tables. The opposite of the UPPER function is the LOWER function (which converts to lower case). The syntax of UPPER is: UPPER(input_string) The input_string is the string value to convert to an upper case value. It can be any of CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB. The return type is the same as the input type. You can use the UPPER function in a WHERE clause. However, unless you have a function-based index on the column, any indexes won’t be used. For example, if you have an index on first_name, a query that uses “WHERE UPPER(first_name)” won’t use this index. You’ll have to create an index on the UPPER(first_name) for this to be used. It’s not required, but it’s just something to keep in mind. For more information about the Oracle UPPER function, including all of the SQL shown in this video and the examples, read the related article here: https://www.databasestar.com/oracle-upper-lower/

As you can see below, a bunch of us have joined forces to make this happen: authors, editors, subject matter experts, app reviewers, and most importantly our amazing readers! ---- About Objective C (from Wikipedia) Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. It was the main programming language used by Apple for the OS X and iOS operating systems, and their respective application programming interfaces (APIs) Cocoa and Cocoa Touch prior to the introduction of Swift. The programming language Objective-C was originally developed in the early 1980s. It was selected as the main language used by NeXT for its NeXTSTEP operating system, from which OS X and iOS are derived.[3] Portable Objective-C programs that do not use the Cocoa or Cocoa Touch libraries, or those using parts that may be ported or reimplemented for other systems, can also be compiled for any system supported by GNU Compiler Collection (GCC) or Clang. Objective-C source code 'implementation' program files usually have .m filename extensions, while Objective-C 'header/interface' files have .h extensions, the same as C header files. Objective-C++ files are denoted with a .mm file extension. About Datatypes: In computer science and computer programming, a data type or simply type is a classification of data which tells the compiler or interpreter how the programmer intends to use the data. Most programming languages support various types of data, for example: real, integer or Boolean. A Data type provides a set of values from which an expression (i.e. variable, function ...) may take its values. The type defines the operations that can be done on the data, the meaning of the data, and the way values of that type can be stored. Data types are used within type systems, which offer various ways of defining, implementing and using them. Different type systems ensure varying degrees of type safety. Almost all programming languages explicitly include the notion of data type, though different languages may use different terminology. Common data types include: integers booleans characters floating-point numbers alphanumeric strings For example, in the Java programming language, the "int" type represents the set of 32-bit integers ranging in value from -2,147,483,648 to 2,147,483,647, as well as the operations that can be performed on integers, such as addition, subtraction, and multiplication. Colors, on the other hand, are represented by three bytes denoting the amounts each of red, green, and blue, and one string representing that color's name; allowable operations include addition and subtraction, but not multiplication. Most programming languages also allow the programmer to define additional data types, usually by combining multiple elements of other types and defining the valid operations of the new data type. For example, a programmer might create a new data type named "complex number" that would include real and imaginary parts. A data type also represents a constraint placed upon the interpretation of data in a type system, describing representation, interpretation and structure of values or objects stored in computer memory. The type system uses data type information to check correctness of computer programs that access or manipulate the data.

Oracle MONTHS_BETWEEN Function
 
02:17
https://www.databasestar.com/oracle-months_between/ The Oracle MONTHS_BETWEEN function allows you to find the number of months between two dates. You can enter two dates and the function returns the difference. This function is often used as part of other calculations. Sometimes you’ll want to know the difference between two dates to perform other functions. The syntax of the MONTHS_BETWEEN function is: MONTHS_BETWEEN(date1, date2) What do these two parameters mean? The function performs date1 minus date2. So, if date1 is larger, the result is positive. If date2 is larger, then the result is negative. What data type is returned? It depends on the values you provide. If the dates are both on the same day of the month (e.g. both on the 10th of the month), then the result is an integer or whole number. If not, then the result will be a decimal value. For more information on the MONTHS_BETWEEN function, including the code used in this video and examples, read the related article here: https://www.databasestar.com/oracle-months_between/

Oracle MOD Function
 
03:17
https://www.databasestar.com/oracle-remainder-mod/ The Oracle MOD function performs a “modulo division” on the numbers you specify. A modulo division is where a division is performed using two numbers, and the remainder is returned by the function. For example, the division of 8/5 is 1.6. Using modulo division, 8/5 will work out there is one 5 contained in the 8, with 3 left over. The MOD function would return 3 in this example. The syntax of the MOD function is: MOD(numerator, denominator) The numerator is the number mentioned first in the division, or the one that is on top of the division sign. In a division such as 15/4, this would be the 15. The denominator is the number mentioned second in the devision, or hte one that is on the bottom of the division sign. In a division such as 15/4, this would be the 4. The parameters can be any numeric data type, and the return type depends on these parameters. This means MOD can return a whole number or a decimal number. The calculation for the Oracle MOD function is: numerator - denominator * FLOOR(numerator / denominator). If the denominator is 0, the function returns the value of the numerator. This is done to prevent “divide by 0” errors. For more information about the MOD function, including how to return every second row, how it’s different to REMAINDER, and to see the SQL code used in these examples, read the related article here: https://www.databasestar.com/oracle-remainder-mod/

WMB Tutorials | Connecting to Database using WMB or IIB
 
07:48
This video explains how to connect to oracle database using WMB (WebSphere Message Broker) or IIB (IBM Integration Bus). In last video we saw how to configure database on WebSphere message broker or IBM integration bus. In this video we will go forward and write actual code to connect to oracle database to fetch data. We will be sending request with username in it and then based on username we will fetch that users data from oracle database. Service URL http://localhost:7080/services/getUserDetails Request { "username":"user1" } Response { "person_id": 1, "given_name": "Dave", "family_name": "Badger", "title": "Mr", "birth_date": "1960-05-01 00:00:00", "username": "user1" } Dummy Data for Connecting to Database using WMB or IIB Demo CREATE TABLE people ( person_id INTEGER NOT NULL PRIMARY KEY, user_name VARCHAR2(100) NOT NULL, given_name VARCHAR2(100) NOT NULL, family_name VARCHAR2(100) NOT NULL, title VARCHAR2(20), birth_date DATE ); INSERT INTO people VALUES (1, 'user1','Dave', 'Badger', 'Mr', date'1960-05-01'); commit; SELECT * FROM people;

Dynamic sql table name variable

This is one of the sql questions that is very commonly asked. I have a web page with a textbox. When I enter a table name in the textbox and when I click "Load Data" button, we want to retrieve data from that respective table and display it on the page. Copy the SQL Script to create the tables from my blog using the link below http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-table-name-variable.html Create the following stored procedure. Notice we are passing table name as a parameter to the stored prcoedure. In the body of the stored procedure we are concatenating strings to build our dynamic sql statement. In our previous videos we discussed that this open doors for SQL injection. Create procedure spDynamicTableName @TableName nvarchar(100) As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from ' + @TableName Execute sp_executesql @sql End So the obvious question that comes to our mind is, why are we not creating parameterised sql statement instead. The answers is we can't. SQL Server does not allow table names and column names to be passed as parameters. Notice in the example below, we are creating a parameterised query with @TabName as a parameter. When we execute the following code, the procedure gets created successfully. Create procedure spDynamicTableName1 @TableName nvarchar(100) As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from @TabName' Execute sp_executesql @sql, N'@TabName nvarchar(100)', @TabName = @TableName End But when we try to execute it we get an error - Must declare the table variable "@TabName" Execute spDynamicTableName1 N'Countries' Add a Web Page to the project that we have been working with in our previous video. Name it "DynamicTableName.aspx". Copy and paste the HTML from my blog using the link below http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-table-name-variable.html Copy and paste the code from my blog in the code-behind page http://csharp-video-tutorials.blogspot.com/2017/04/dynamic-sql-table-name-variable.html At this point, run the application and type the following text in the "Table Name" textbox and click "Load Data" button. Notice "SalesDB" database is dropped. Our application is prone to SQL injection as we have implemented dynamic sql in our stored procedure by concatenating strings instead of using parameters. Employees; Drop database SalesDB One way to prevent SQL injection in this case is by using SQL Server built-in function - QUOTENAME(). We will discuss QUOTENAME() function in detail in our next video. For now understand that by default, this function wraps that string that is passed to it in a pair of brackets. SELECT QUOTENAME('Employees') returns [Employees] Modify the stored procedure to use QUOTENAME() function as shown below. Alter procedure spDynamicTableName @TableName nvarchar(100) As Begin Declare @sql nvarchar(max) Set @sql = 'Select * from ' + QUOTENAME(@TableName) Execute sp_executesql @sql End At this point, type the following text in the "Table Name" textbox and click "Load Data" button. Notice you will see a message - Invalid object name 'Employees; Drop database SalesDB'. Also "SalesDB" database is not dropped. Employees; Drop database SalesDB The entire text in "Table Name" textbox is wrapped in a pair of brackets by the QUOTENAME function and is treated as table name. Since we do have a table with the specified name, we get the error - Invalid object name.

What is NoSQL Database? || SQL vs NoSQL || What database actually FACEBOOK uses?
 
38:31
What is NoSQL? NoSQL encompasses a wide variety of different database technologies that were developed in response to the demands presented in building modern applications: Developers are working with applications that create massive volumes of new, rapidly changing data types — structured, semi-structured, unstructured and polymorphic data. Long gone is the twelve-to-eighteen month waterfall development cycle. Now small teams work in agile sprints, iterating quickly and pushing code every week or two, some even multiple times every day. Applications that once served a finite audience are now delivered as services that must be always-on, accessible from many different devices and scaled globally to millions of users. Organizations are now turning to scale-out architectures using open source software, commodity servers and cloud computing instead of large monolithic servers and storage infrastructure. NoSQL Database Types: Document databases pair each key with a complex data structure known as a document. Documents can contain many different key-value pairs, or key-array pairs, or even nested documents. Graph stores are used to store information about networks of data, such as social connections. Graph stores include Neo4J and Giraph. Key-value stores are the simplest NoSQL databases. Every single item in the database is stored as an attribute name (or 'key'), together with its value. Examples of key-value stores are Riak and Berkeley DB. Some key-value stores, such as Redis, allow each value to have a type, such as 'integer', which adds functionality. Wide-column stores such as Cassandra and HBase are optimized for queries over large datasets, and store columns of data together, instead of rows. The Benefits of NoSQL When compared to relational databases, NoSQL databases are more scalable and provide superior performance, and their data model addresses several issues that the relational model is not designed to address: Large volumes of rapidly changing structured, semi-structured, and unstructured data Agile sprints, quick schema iteration, and frequent code pushes Object-oriented programming that is easy to use and flexible Geographically distributed scale-out architecture instead of expensive, monolithic architecture What database actually FACEBOOK uses?: 1.

Reaktor Talks: Tour de Data Types: VARCHAR2 or CHAR(255)?, Andreas Scherbaum
 
50:08
Ever wondered what might be the best data type for a certain use case? Is it better to use INTEGER or BIGINT, and should you use TIMESTAMP or is it better to use TIMESTAMPTZ? When is the last time you migrated a legacy database and wondered what to use as replacement for VARCHAR2 or CHAR(255)? How to store IP addresses or geographical data, does that fit into VARCHAR or is there something more suitable? PostgreSQL 9.6 comes with around 40 different data types preinstalled. This talk looks beyond INTEGER and VARCHAR and dives into some of the lesser known PostgreSQL data types. Use cases and examples show which data type is a good fit for a certain situation.

You can rename a table or a column temporarily by giving another name known as alias. The use of table aliases means to rename a table in a particular SQL statement. The renaming is a temporary change and the actual table name does not change in the database. The column aliases are used to rename a table's columns for the purpose of a particular SQL query.
