This means a given student can be enrolled into many courses and a given course can have many students enrolled. Below is the question asked in an interview for SQL Server Developer role. Write a SQL script to insert data into StudentCourses table. Here are the rules that your script should follow. 1. There will be 2 inputs for the script Student Name - The name of the student who wants to enroll into a course Course Name - The name of the course the student wants to enroll into 2. If the student is already in the Students table, then use that existing Student Id. If the student is not already in the Students table, then a row for that student must be inserted into the Students table, and use that new student id. 3. Along the same lines, if the course is already in the Courses table, then use that existing Course Id. If the course is not already in the Courses table, then a row for that course must be inserted into the Courses table, and use that new course id. 4. There should be no duplicate student course enrollments, i.e a given student must not be enrolled in the same course twice. For example, Tom must not be enrolled in C# course twice. Answer : To avoid duplicate student course enrollments create a composite primary key on StudentId and CourseId columns in StudentCourses table. With this composite primary key in place, if someone tries to enroll the same student in the same course again we get violation of primary key constraint error. Alter table StudentCourses Add Constraint PK_StudentCourses Primary Key Clustered (CourseId, StudentId) Here is the SQL script that inserts data into the 3 tables as expected Declare @StudentName nvarchar(50) = 'Sam' Declare @CourseName nvarchar(50) = 'SQL Server' Declare @StudentId int Declare @CourseId int -- If the student already exists, use the existing student ID Select @StudentId = Id from Students where StudentName = @StudentName -- If the course already exists, use the existing course ID Select @CourseId = Id from Courses where CourseName = @CourseName -- If the student does not exist in the Students table If (@StudentId is null) Begin -- Insert the student Insert into Students values(@StudentName) -- Get the Id of the student Select @StudentId = SCOPE_IDENTITY() End -- If the course does not exist in the Courses table If (@CourseId is null) Begin -- Insert the course Insert into Courses values(@CourseName) -- Get the Id of the course Select @CourseId = SCOPE_IDENTITY() End -- Insert StudentId & CourseId in StudentCourses table Insert into StudentCourses values(@StudentId, @CourseId) If required, we can very easily convert this into a stored procedure as shown below. Create procedure spInsertIntoStudentCourses @StudentName nvarchar(50), @CourseName nvarchar(50) as Begin Declare @StudentId int Declare @CourseId int Select @StudentId = Id from Students where StudentName = @StudentName Select @CourseId = Id from Courses where CourseName = @CourseName If (@StudentId is null) Begin Insert into Students values(@StudentName) Select @StudentId = SCOPE_IDENTITY() End If (@CourseId is null) Begin Insert into Courses values(@CourseName) Select @CourseId = SCOPE_IDENTITY() End Insert into StudentCourses values(@StudentId, @CourseId) End Use the following statement to execute the stored procedure Execute spInsertIntoStudentCourses 'Tom','C#'

PL/SQL tutorial : Trigger in Oracle Database 11g Complete guide
 
26:21
Learn in depth about trigger in oracle database 11g, and usage of trigger in Database, different types of trigger with syntax for various events along with writing advance trigger and capturing all details regarding authentication. Explained Instead of trigger. Trigger in Oracle, Trigger in PL/SQL, Oracle Trigger, PL/SQL Trigger, What is Trigger in pl/sql, How to use Trigger in pl/sql, How to write a Trigger in oracle, How to design Trigger in pl/sql, DDL trigger, DML trigger, Instead of trigger, Compound trigger, Logon trigger, Introduction to Triggers You can write triggers that fire whenever one of the following operations occurs: DML statements (INSERT, UPDATE, DELETE) on a particular table or view, issued by any user DDL statements (CREATE or ALTER primarily) issued either by a particular schema/user or by any schema/user in the database Database events, such as logon/logoff, errors, or startup/shutdown, also issued either by a particular schema/user or by any schema/user in the database Triggers are similar to stored procedures. A trigger stored in the database can include SQL and PL/SQL or Java statements to run as a unit and can invoke stored procedures. However, procedures and triggers differ in the way that they are invoked. A procedure is explicitly run by a user, application, or trigger. Triggers are implicitly fired by Oracle when a triggering event occurs, no matter which user is connected or which application is being used. How Triggers Are Used Triggers supplement the standard capabilities of Oracle to provide a highly customized database management system. For example, a trigger can restrict DML operations against a table to those issued during regular business hours. You can also use triggers to: Automatically generate derived column values Prevent invalid transactions Enforce complex security authorizations Enforce referential integrity across nodes in a distributed database Enforce complex business rules Provide transparent event logging Provide auditing Maintain synchronous table replicates Gather statistics on table access Modify table data when DML statements are issued against views Publish information about database events, user events, and SQL statements to subscribing applications Linkedin: https://www.linkedin.com/in/aditya-kumar-roy-b3673368/ Facebook: https://www.facebook.com/SpecializeAutomation/

Check Last Modified DateTime for An Object (Table,Stored Procedure,Trigger etc.) in SQL Server

We as SQL Server developers send our DDL Scripts ( Add New Column, Drop some column from table, or Alter Stored Procedure) to DBA. After deployment we verify those changes and sometime it happens that the changes are not done. Maybe DBA has missed one of the script to run. If we can get the last modified date for object ( Table,Stored Procedure, View etc) that can confirm the changes are done on given date. blog post link for scripts used in this video http://sqlage.blogspot.com/2014/01/tsql-how-to-check-when-object-table.html

How to Resolve Oracle SQL Parent Key Not Found (ORA-02291)
 
05:49
In this video, we’ll explain what the ORA-02291 “parent key not found” error is, see an example, and look at how to resolve it. This error usually happens when we try to insert data into a table. It looks like this: Error is: ORA-02291: integrity constraint (constraint_name) violated - parent key not found So what does this error mean? It means we’re trying to insert data into a child table, and there is no related record in the parent table. If a foreign key has been set up to enforce this relationship, there needs to be a parent to insert a child that refers to it. Watch the video to see an example of this error as well as how to resolve it. For more information on Oracle SQL, refer to the Database Star website here: https://www.databasestar.com/

8. Use LOG ERRORS to suppress SQL errors at the row level.
 
06:23
The impact of a non-query DML statement is usually "all or nothing". If my update statement identifies 100 rows to change, then either all 100 rows are changed or none are. And none might be the outcome if, say, an error occurs on just one of the rows (value too large to fit in column, NULL value for non-NULL column, etc.). But if you have a situation in which you would really like to "preserve" as many of those row-level changes as possible, you can add the LOG ERRORS clause to your DML statement. Then, if any row changes raise an error, that information is written to your error log table, and processing continues. IMPORTANT: if you use LOG ERRORS, you must must must check that error log table immediately after the DML statement completes. You should also enhance the default error log table.

What is a Bump Stock? Should it be illegal?!
 
06:45
How does a bump stock work? This video will demonstrate how a bumpstock works when attached to a Semi-Automatic AR-15. This has been in the news quite a bit lately as the United States government holds hearings on whether this gun accessory should be banned. This video shows how a Bump Stock works, and what it can accomplish while attached to an AR-15. It is currently illegal for private United states citizens to own a fully automatic firearm. (As of 1986) BUT bump stocks are only an accessory to a rifle, and don't actually alter the gun to fire automatically. So they are totally legal as of the posting of this video, anyone can buy one, and anyone can shoot with one. The question is: Should it stay legal? or should this accessory be regulated? Would you like to see more videos like this in the future?

Alert creation in oracle Apps
 
07:43
Overview: You can use alerts simply to notify one person/multiple persons about an event or some data change. There are two type of alerts Event based Alerts Periodic Alerts Event based Alerts: These Alerts are fired/triggered based on some change in data in the database. Ex: If you want to notify your manager when you create an item in the inventory you can use Event based alerts. When you create an item in the inventory it will create a new record in mtl_system_items_b, here inserting a record in the table is an event so when ever a new record is inserted it will send the alert. In same alert you can also send the information related to that particular item. Periodic Alerts: These Alerts are triggered hourly, daily, weekly, monthly or yearly based on your input. Ex: If you want to know list of all items created on that day at the end of day you can use periodic alerts repeating periodically by single day. This alert is not based on any changes to database. This alert will notify you everyday regardless of data exists or not that means even if no items are created you will get a blank notification.

Difference Between Delete and Truncate
 
03:41
Below is link for Useful Pl/SQL Books http://goo.gl/XMy0tt ---------------------------------------------------------- Difference Between Delete and Truncate in Detail On bigger picture they serve the same purpose but there are many Differences listed with examples Point Delete Truncate 1. Data Recovery Delete: Come under the DML Category, we need to commit or Rollback explicitly to make the changes permanent, so we can recover the data by Rollback command fully with in a session or up to a point if Save Points are used Fall In DDL Category (DDL Command issue the Auto commit implicitly) so no chances of Recovery even not using the Flashback table method. But Truncate operations are also logged , they didn’t generate redo SQL but they are logged , view for truncated data info V$LOGMNR_CONTENTS 2. Data Removal Delete Can remove all or selected data using the Where Clause predicates. Or we can say delete any subset of rows We can Truncate complete table or a partition or sub partition of a table. 3. Speed Delete is Slower because oracle maintain the redo logs for Read Consistency (so that every session connected can see a consistent data at a given point of time ) Delete is very time consuming activity especially when table have numerous indexes and Triggers associated with table Faster as no data logs are maintained no associated trigger firing. 4. DML Triggers Firing DML (Delete) triggers associated with table will fire. DML Trigger will not fire in case of truncate method. 5. Flashback Technology Data can be recovered even after commit operation using Flashback Table options Flashback_transaction_query table will give what to recover and up to which point. Data cannot be recovered in truncate method by Flashback table option. 6. Referential Integrity Constraint Behavior if we don’t have related data in child table then we can delete the data from the parent table or we have variants like On Delete Cascade & on Delete set Null. We can’t truncate a table with enable Referential Integrity Constraint, even there is no data in the child table, we have to disable or drop the constraint if we want to truncate the table. Exception: Truncate is possible if the FK is self-referential means primary key and foreign key are on the same table. 7. Space De allocation or Space Utilization No extent reset with delete when deleting rows from a table, extents are not de allocated, So if there were 50 extents in the table before the deletion, there will still be 50 after the deletion. Truncate: When a table is truncated it will free the space allocated except in case of reuse storage clause. This space can subsequently be used only by new data in the table or cluster resulting from insert or update operations .All extents are de allocated leaving only the extents specified when the table was originally created .Example So if the table was originally created with min extents 3, there will be 3 extents remaining when the tables is truncated. When you truncate a table, NEXT is automatically reset to the last extent deleted. 8. High Water Mark Delete will not reset the high water mark Truncate will reset the High Water mark which is very important for performance point of view as in case of full table scan and full index scan oracle will read all the block under high water mark this makes a lot of difference in terms of performance. 9. Cluster No as such restriction with delete. You cannot individually truncate a table that is part of a cluster. You must truncate the cluster, Delete all rows from the table, or drop and re-create the table. 10. Information Capturing Delete : we can capture the row information what we have deleted using Delete Method, f you are deleting multiple records then use composite data types (collections & records) Truncate Don’t have this feature of capturing the deleted records. 11. Function Based Index Impact DELETE You cannot delete rows from a table if a function-based index on the table has become invalid. You must first validate the function-based index. Truncate: No as such restriction 12. UNUSABLE Indexes Delete no as such feature. Truncate if table is not empty then truncate make all unusable indexes to useable. 13. Complex views You cannot delete data from a Complex view except through INSTEAD OF triggers. But we can delete data from simple Views and MV. We cannot truncate a view simple or complex but you can truncate MV with special Features like Preserve MV Logs and Purge MV Logs. 14. Privileges Delete You need to provide delete table privilege on object. Truncate you must have drop table privilege there is no truncate table privilege exists. 15. Domain Index No as such restriction You cannot truncate the object having domain index in invalid or In progress state

Top 3 Foods to Help Irritable Bowel Syndrome and Stomach Issues

Click Here to Subscribe: http://Bit.ly/ThomasVid Website: http://ThomasDeLauer.com Top 3 Foods to Help Irritable Bowel Syndrome and Stomach Issues Top Three Foods for IBS What is IBS? IBS is a cluster of symptoms, including cramping, diarrhea, constipation, bloating and gas. The exact cause of IBS is not understood, leading to difficulties in treatment. ● It does appear that IBS is more common in more developed countries Likely factors that may lead to IBS include: ● Intestinal microbiota imbalance ● Inflammation ● Intestinal infections ● Serotonin imbalance One common recommendation is the low FODMAP diet, where one avoids foods that contain fermentable carbohydrates ● It is thought that these foods can lead to increased liquid in the intestine and then to diarrhea, as well as bloating and gas ● Restrictive diet where it is nearly impossible to get sufficient vitamins and minerals ● No conclusive research showing this to help Different foods may cause symptoms for different people ● Pay attention to personal triggers ● Keeping a food journal can help If there is no exact science as to what foods to avoid, is there any supporting foods to consume? Top 3 Foods for IBS 1. Turmeric Curcumin, the most active component of turmeric, displays the following health benefits: ● Anti-inflammatory properties ● Anti-bacterial properties ● Spasmolytic activities Case Study A 2004 study published in the Journal of Alternative and Complementary Medicine found that turmeric extract improved IBS symptoms; the study was not placebo controlled 207 volunteers with IBS were given either one or two tablets of turmeric extract daily for 8 weeks and then reported their symptoms. A significant reduction in reported pain and symptoms occurred, however there was no difference between the groups. Roughly ⅔ of participants reported a decrease in their symptoms following treatment. 2. Peppermint Oil Many studies exists showing the potential for improvement of IBS symptoms with peppermint oil Case Study A 2014 study published in the Journal of Clinical Gastroenterology reviewed peer reviewed published studies on peppermint oil and IBS symptoms and found peppermint oil more effective than placebo for improvement of both abdominal pain and global IBS symptoms One possible problem with peppermint oil is an increase in heartburn symptoms, although this side effect occurred less frequently than did improvement of IBS symptoms, so still good for most of those who suffer with IBS. Probiotics It is well known that the population of gut bacteria can have an impact on our health People with IBS usually have gut flora that has changed, so foods that encourage the growth of beneficial bacteria in the gut is likely to help IBS symptoms Case Study A 2000 study published in The American Journal of Gastroenterology found an improvement in IBS symptoms Recruited 60 otherwise healthy patients with IBS and split them into a control group and a test group. The test group received Lactobacillus plantarum daily for 4 weeks. The test group experienced improved flatulence during the 4 weeks and better GI function when compared to the control group 12 months after the experiment. Lactobacillus plantarum is the most prevalent bacteria found in sauerkraut, a food made from fermented cabbage. Other probiotic foods include miso, kimchi, kombucha, yogurt, and coconut kefir References 1.

SQL: WITH Clause
 
06:11
In this tutorial, you'll learn will learn how to use with clause 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.

What is a VIEW in Oracle? An Oracle VIEW, in essence, is a virtual table that does not physically exist. Rather, it is created by a query joining one or more tables. Create VIEW Syntax The syntax for the CREATE VIEW Statement in Oracle/PLSQL is: CREATE VIEW view_name AS SELECT columns FROM tables [WHERE conditions]; view_name The name of the Oracle VIEW that you wish to create. WHERE conditions Optional. The conditions that must be met for the records to be included in the VIEW. Example Here is an example of how to use the Oracle CREATE VIEW: CREATE VIEW sup_orders AS SELECT suppliers.supplier_id, orders.quantity, orders.price FROM suppliers INNER JOIN orders ON suppliers.supplier_id = orders.supplier_id WHERE suppliers.supplier_name = 'Microsoft'; This Oracle CREATE VIEW example would create a virtual table based on the result set of the SELECT statement. You can now query the Oracle VIEW as follows: SELECT * FROM sup_orders; Update VIEW You can modify the definition of an Oracle VIEW without dropping it by using the Oracle CREATE OR REPLACE VIEW Statement. Syntax The syntax for the CREATE OR REPLACE VIEW Statement in Oracle/PLSQL is: CREATE OR REPLACE VIEW view_name AS SELECT columns FROM table WHERE conditions; view_name The name of the Oracle VIEW that you wish to create or replace. Example Here is an example of how you would use the Oracle CREATE OR REPLACE VIEW Statement: CREATE or REPLACE VIEW sup_orders AS SELECT suppliers.supplier_id, orders.quantity, orders.price FROM suppliers INNER JOIN orders ON suppliers.supplier_id = orders.supplier_id WHERE suppliers.supplier_name = 'Apple'; This Oracle CREATE OR REPLACE VIEW example would update the definition of the Oracle VIEW called sup_orders without dropping it. If the Oracle VIEW did not yet exist, the VIEW would merely be created for the first time. Drop VIEW Once an Oracle VIEW has been created, you can drop it with the Oracle DROP VIEW Statement. Syntax The syntax for the DROP VIEW Statement in Oracle/PLSQL is: DROP VIEW view_name; view_name The name of the view that you wish to drop. Example Here is an example of how to use the Oracle DROP VIEW Statement: DROP VIEW sup_orders; This Oracle DROP VIEW example would drop/delete the Oracle VIEW called sup_orders. Frequently Asked Questions Question: Can you update the data in an Oracle VIEW? Answer: A VIEW in Oracle is created by joining one or more tables. When you update record(s) in a VIEW, it updates the records in the underlying tables that make up the View. So, yes, you can update the data in an Oracle VIEW providing you have the proper privileges to the underlying Oracle tables. Question: Does the Oracle View exist if the table is dropped from the database? Answer: Yes, in Oracle, the VIEW continues to exist even after one of the tables (that the Oracle VIEW is based on) is dropped from the database. However, if you try to query the Oracle VIEW after the table has been dropped, you will receive a message indicating that the Oracle VIEW has errors. If you recreate the table (the table that you had dropped), the Oracle VIEW will again be fine.
