Solution 3

main difference

store procedure's can not used as inline Query

while function is used for inline query

eg.

SQL

select (exec sp_abc 'a1','a2') as a,* from tbl_abc --will give error because sp can't be used as inline Query

SQL

select fn_concat(a1, a2) as a,* from tbl_abc--functions can be used as inline query

another important things are,
* Function have limited error handling then Store-procedures
* Function can not use temporary tables
* Function can not call SP, but in sp you can call function using select statement

Happy Coding!
:)

Solution 1

Use a user-defined function when you want to compute and return a value for use in other SQL statements;
Refer more: here[^]
Use a stored procedure when you want instead is to group a possibly-complex set of SQL statements.
Refer more:
Link 1[^]
Link 2[^]
Link 3[^]
These are two pretty different use cases, after all!
