In this video we will learn how to get decimal/float output from Integer division in SQL Server.
I am creating this video to answer once of the question that I posted while back for TSQL Interview Question list
"If I run Select 100/11 what output will I get?"
When you divide Integer by an Integer in SQL Server, SQL Server returns Integer output.
As we can see from our above example, SQL Server output is Integer for Integers division. If we want to get float or Decimal output, Either our denominator or Numerator should be float or decimal type.
If we have both denominator or numerator as Integers, we can use convert or cast functions to convert one of them to float/decimal so we can get our results as float/decimal.
There are multiple techniques you can use to convert/cast to integer to float/decimal, here are some examples
SELECT CAST(100 AS FLOAT) /11 AS OutputResult
SELECT 100/CAST(11 AS FLOAT) AS OutputResult
SELECT 100/CAST(11 AS DECIMAL(12,0)) AS OutputResult
SELECT CAST(100 AS DECIMAL(12,0))/11 AS OutputResult

How to Concatenate String and Integer Values in SQL Server ( + Sign vs CONCAT ) - TSQL Tutorial
Working with Databases is fun. On daily basis we save data into tables in different columns and often we need to write queries which involve concatenation of multiple columns of different datatypes to produce our final output. In below example we have saved some data into #Customer Table which has Street Address column as string and zip as INT. we want to produce Full Address by concatenating these columns. To concatenate we can use + sign but this works only with String values. So if we have any Integer value/s we have to convert them to String first. We can use Cast or Convert function to convert Integer value to string. Also if there is any Null value among which values we are concatenating , our output will be Null by using + sign. To take care of that part we can use either ISNULL() or Coalesce Function to replace NULL with blank value in SQL Server.
In SQL Server 2012 and Later versions, CONCAT function was introduced. You can concatenate multiple values by using this function. Fun part of this function is you don't have to worry about Null outcome as it will Ignore Null values and also you don't have to worry about converting INT into strings, It will take care of that automatically. So if you are using new versions such as 2012 or later, start taking advantage of this function.

This oracle tutorial gives a brief concept about advantages using anchored declaration in oracle pl sql. While using normal variable type is ok until data type or size of columns in table is not altered, but as soon as they are altered there is a possibilities of occurrence of errors, i.e. data type changes from numeric field to alpha numeric field. Just go through this oracle tutorial and you will definitely get some concept of advantages of using %TYPE and %ROWTYPE.

Bit is integer data type that can store 0,1 or Null. Bit take One byte ( 8 Bits) in memory to store these values for us. We often use this data type for the columns where we want to show if the record is active or In- Active. You can call those type of columns as status columns/ Flag Columns etc.
As we know that bit can store only three possible values but when it comes to inserting that values it is Bit confusing. If you will insert 'TRUE' , It will take that as 1. If you will insert 'False', SQL Server will translate that to 0. There are more confusing part to it;)
Watch the video and you will see what I am talking about BIT Data type in SQL Server.

In this video ,we will generate the script that will return us all the table names with column names and data type of those columns. We often need this information. Let's say we are going to prepare mapping document for load the data from Source Database to Destination database. We can get the list of all tables with column names and data types from Source Database and Destination Database and then paste in Excel and map the required input columns to output columns for ETL Process.

In this tutorial, you'll learn how to make use of sequence generator.
PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database.
PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces.
PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard.
The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3]
PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables.
PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7]
The StepSqlite product is a PL/SQL compiler for the popular small database SQLite.
PL/SQL Program Unit
A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database.
The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label.
Package
Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are:
Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation.
Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.

Java SE 8 (JDK 8) Introduced a fundamentally new way of programming in Java with the introduction of Lambda expressions.
Lambda provides a simple way to pass functionality as an argument to another method, such as what action should be taken when someone clicks a button, or how to sort a set of names. Lambda expressions enable you to do this, to treat functionality as method argument, or code as data.
You may have heard about Lambda, and are curious what impact it will have on you as a Java developer.
This 3 week course is designed to answer your questions and more.
* Have you ever wondered what lambda expressions are in Java?
* Have you ever wanted to write parallel code in Java without worrying about threads and locking?
* Have you ever wanted to process collections of data without using loops?
* Have you ever wanted to do functional programming in Java?
All of these questions will be answered in this practical hands-on MOOC.

try convert function in sql
sql server try_convert
try_convert in sql server 2012
try convert sql
try_parse vs try_convert sql server
In this video we will discuss
TRY_CONVERT function
Difference between CONVERT and TRY_CONVERT functions
Difference between TRY_PARSE and TRY_CONVERT functions
TRY_CONVERT function
Introduced in SQL Server 2012
Converts a value to the specified data type
Returns NULL if the provided value cannot be converted to the specified data type
If you request a conversion that is explicitly not permitted, then TRY_CONVERT fails with an error
Syntax : TRY_CONVERT ( data_type, value, [style] )
Style parameter is optional. The range of acceptable values is determined by the target data_type. For the list of all possible values for style parameter, please visit the following MSDN article
https://msdn.microsoft.com/en-us/library/ms187928.aspx
Example : Convert string to INT. As the string can be converted to INT, the result will be 99 as expected.
SELECT TRY_CONVERT(INT, '99') AS Result
Example : Convert string to INT. The string cannot be converted to INT, so TRY_CONVERT returns NULL
SELECT TRY_CONVERT(INT, 'ABC') AS Result
Example : Converting an integer to XML is not explicitly permitted. so in this case TRY_CONVERT fails with an error
SELECT TRY_CONVERT(XML, 10) AS Result
If you want to provide a meaningful error message instead of NULL when the conversion fails, you can do so using CASE statement or IIF function.
Example : Using CASE statement to provide a meaningful error message when the conversion fails.
SELECT
CASE WHEN TRY_CONVERT(INT, 'ABC') IS NULL
THEN 'Conversion Failed'
ELSE 'Conversion Successful'
END AS Result
Output : As the conversion fails, you will now get a message 'Conversion Failed' instead of NULL
Example : Using IIF function to provide a meaningful error message when the conversion fails.
SELECT IIF(TRY_CONVERT(INT, 'ABC') IS NULL, 'Conversion Failed',
'Conversion Successful') AS Result
What is the difference between CONVERT and TRY_CONVERT
CONVERT will result in an error if the conversion fails, where as TRY_CONVERT will return NULL instead of an error.
Since ABC cannot be converted to INT, CONVERT will return an error
SELECT CONVERT(INT, 'ABC') AS Result
Since ABC cannot be converted to INT, TRY_CONVERT will return NULL instead of an error
SELECT TRY_CONVERT(INT, 'ABC') AS Result
Example : Using TRY_CONVERT() function with table data. We will use the following Employees table for this example.
SQL Script to create Employees table
Create table Employees
(
Id int primary key identity,
Name nvarchar(10),
Age nvarchar(10)
)
Go
Insert into Employees values ('Mark', '40')
Insert into Employees values ('John', '20')
Insert into Employees values ('Amy', 'THIRTY')
Insert into Employees values ('Ben', '21')
Insert into Employees values ('Sara', 'FIFTY')
Insert into Employees values ('David', '25')
Go
The data type of Age column is nvarchar. So string values like (THIRTY, FIFTY ) are also stored. Now, we want to write a query to convert the values in Age column to int and return along with the Employee name. Notice TRY_CONVERT function returns NULL for the rows where age cannot be converted to INT.
SELECT Name, TRY_CONVERT(INT, Age) AS Age
FROM Employees
If you use CONVERT instead of TRY_CONVERT, the query fails with an error.
SELECT NAME, CONVERT(INT, Age) AS Age
FROM Employees
The above query returns the following error
Conversion failed when converting the nvarchar value 'THIRTY' to data type int.
Difference between TRY_PARSE and TRY_CONVERT functions
TRY_PARSE can only be used for converting from string to date/time or number data types where as TRY_CONVERT can be used for any general type conversions.
For example, you can use TRY_CONVERT to convert a string to XML data type, where as you can do the same using TRY_PARSE
Converting a string to XML data type using TRY_CONVERT
SELECT TRY_CONVERT(XML, '[root][child/][/root]') AS [XML]
Converting a string to XML data type using TRY_PARSE
SELECT TRY_PARSE('[root][child/][/root]' AS XML) AS [XML]
The above query will result in the following error
Invalid data type xml in function TRY_PARSE
Another difference is TRY_PARSE relies on the presence of .the .NET Framework Common Language Runtime (CLR) where as TRY_CONVERT does not.

This is one in a series of videos about creating an application using Oracle APEX 5. In this video we create two lists of values (LOVs) in the Shared Components section of our application. We use each LOV in place of a field in a form. We see how APEX will help us write the SQL for a LOV. The difference between a "display value"and a "return value"is discussed. Finally, we display the primary key field in a form, which APEX hides by default. See the primary key field in a form can be helpful during application development.

In this tutorial I will demonstrate how to utilize format strings to make printing things much more organized. I mainly focus on the System.out.printf() command, but I also touch on System.out.format() and String.format(). Hopefully you find this to be useful!
If you need more reference for format strings, here is a lot more information than you'll ever need:
http://docs.oracle.com/javase/7/docs/api/java/util/Formatter.html
Here's some more information:
http://docs.oracle.com/javase/tutorial/java/data/numberformat.html
And here's a simple demonstration of the information:

Java Programming for Mobile Developers Part 9 !
byte:
Byte data type is an 8-bit signed two's complement integer.
Minimum value is -128 (-2^7)
Maximum value is 127 (inclusive)(2^7 -1)
Default value is 0
Byte data type is used to save space in large arrays, mainly in place of integers, since a byte is four times smaller than an int.
Example: byte a = 100 , byte b = -50
short:
Short data type is a 16-bit signed two's complement integer.
Minimum value is -32,768 (-2^15)
Maximum value is 32,767 (inclusive) (2^15 -1)
Short data type can also be used to save memory as byte data type. A short is 2 times smaller than an int
Default value is 0.
Example: short s = 10000, short r = -20000
int:
Int data type is a 32-bit signed two's complement integer.
Minimum value is - 2,147,483,648.(-2^31)
Maximum value is 2,147,483,647(inclusive).(2^31 -1)
Int is generally used as the default data type for integral values unless there is a concern about memory.
The default value is 0.
Example: int a = 100000, int b = -200000
long:
Long data type is a 64-bit signed two's complement integer.
Minimum value is -9,223,372,036,854,775,808.(-2^63)
Maximum value is 9,223,372,036,854,775,807 (inclusive). (2^63 -1)
This type is used when a wider range than int is needed.
Default value is 0L.
Example: long a = 100000L, int b = -200000L
float:
Float data type is a single-precision 32-bit IEEE 754 floating point.
Float is mainly used to save memory in large arrays of floating point numbers.
Default value is 0.0f.
Float data type is never used for precise values such as currency.
Example: float f1 = 234.5f
double:
double data type is a double-precision 64-bit IEEE 754 floating point.
This data type is generally used as the default data type for decimal values, generally the default choice.
Double data type should never be used for precise values such as currency.
Default value is 0.0d.
Example: double d1 = 123.4
boolean:
boolean data type represents one bit of information.
There are only two possible values: true and false.
This data type is used for simple flags that track true/false conditions.
Default value is false.
Example: boolean one = true
char:
char data type is a single 16-bit Unicode character.
Minimum value is '\u0000' (or 0).
Maximum value is '\uffff' (or 65,535 inclusive).
Char data type is used to store any character.
Example: char letterA ='A'
Reference Data Types:
Reference variables are created using defined constructors of the classes. They are used to access objects. These variables are declared to be of a specific type that cannot be changed. For example, Employee, Puppy etc.
Class objects, and various type of array variables come under reference data type.
Default value of any reference variable is null.
A reference variable can be used to refer to any object of the declared type or any compatible type.
Example: Animal animal = new Animal("giraffe");
