SQL Server T-SQL stored procedure triggers

One, stored procedures

A stored procedure is a set of T-SQL statements that are compiled in a single execution plan

Stored procedures: Like functions are saved in the database (programmability)

Advantages of stored procedures:

1. Allow modular programming

2. Allow for faster execution if an operation requires a large number of T-SQL code or needs to be repeated, the stored procedure will be faster than the T-SQL batch code execution. It is parsed and optimized when the stored procedure is created, and you can use the in-memory version of the procedure after the first execution of the procedure.

3. Reduce network traffic

4. An operation that requires hundreds of lines of T-SQL code can be implemented by a separate statement that executes the procedure code without the need to send hundreds of lines of code in the network.

5. Use as a security mechanism
