Function is returning NULL

Hi Luqman,

 

you are merging SQL User Defined Table Functions and SQL Stored Procedures!

 

Only Stored Procedures can be called with the SQL Command CALL!

Stored Procedures are created using the SQL Command CREATE PROCEDURES.

 

User Defined Table Functions must be called in an SELECT statement.

Select * From Table(MyUDTF(Parm1, Parm2, ... ParmN)) as X

They are created over the SQL Command CREATE FUNCTION.

 

An please have a look at the red book:

Stored Procedures, Triggers and User Defined Functions
