Sajjadwhat is the differnce between stored Procedure and stored Functions ????|||please check first in any search engine.|||Functions are easier to fold into SELECT statements, as they return scalar or table values.
Stored procedures have fewer programming limitations than user-defined functions, but must be run independently and not as part of a select statement.sql
