What is Sql Database Stored procedure how to use

Sql Database Stored procedure:

Stored procedure:

In this Post we are talking about Stored procedure in sql, how to create it's type and use also how to use with web application. if you want to learn programming then start from  introduction of and if you are new fir sql the see the post of sql introduction.
In a Sql database management system (DBMS), a stored procedure is a group of SQL statements with an assigned name that's stored in the database in compiled form so that it can be shared by a number of programs.

A stored procedure is prepared SQL code that you save so you can re-use this code over and over again.  So if you think about a sql-query that you write over and over again, And having to write that query each time you would save it as a stored procedure and then use the stored procedure to execute the SQL code that you saved as part of the stored procedure.

Difference between Sql Stored Procedure and Function:

There are fallowing difference :-

  • Sql Functions can have only input parameters but Procedures can have input/output parameters.
  • Sql Functions can be called from Procedure while Procedures cannot be called from Function.
  • Sql Function can be embedded in a SELECT statement. But Procedures cannot be utilized in a SELECT statement.
  • The most important feature of stored procedures over function is to retention and reuse the execution plan while in case of function it will be compiled every time.
  • Functions that return tables can be treated as another rowset. This can be used in JOINs with other tables.
  • Inline Function can be thought of as views that take parameters and can be used in JOINs and other Rowset operations.
  • Exception can be handled by try-catch block in a Procedure whereas try-catch block cannot be used in a Function.
  • We can go for Transaction Management in Procedure whereas we can't go in Function.
  • Stored procedure allows modular programming.
  • Stored Procedure can reduce network traffic.
  • Stored procedures provide better security to your data.
