How to Create Stored Procedure & Trigger in SQL Server In few words, a stored procedure is more flexible to write any code that you want, while functions have a rigid structure and functionality. Stored Procedure Vs Trigger. Function. 2. A trigger is a special kind of stored procedure-one that cannot be executed explicitly, instead of attached to an event. It includes all the statements of SQL, but we can also use if, then, else blocks and while loops.

It may return 1 or more values to client as parameters (not rows) 2. Therefore, if you want to update a stored procedure, you only have to update it at one place. SP may or may not return a value but UDF must return a value. Whereas, Procedures can have output or input parameters. This value comming out must be done via the RETURN.

I can create view x which might represent select * from table a join table b where a.key = b.key join table c on a.key = c.key Now to call that much more complex query all I have to do is say select * from x. T. Performance: the ability for the stored procedure to reuse a query plan (stored procedure cache) Can reuse the same stored procedure for more than one report (may minimize errors or duplication) DBA can tune more effectively, if needed; Permits the DBMS to secure the object, if needed Static Count vs Dynamic Count (Very advanced, gurus take your shot) 1 Insert_Update Stored Procedure and returning Identity 1 Read row in a CLR Stored Procedure Without output parameter 2 We can call a stored .
