MySQL - SELECT INTO within a Stored Procedure

Question

We have a lot of stored procedures which have an OUT parameter which we are assigning a value to by using SELECT LAST_INSERTID() INTO p_AutoNumber .

After this, we need to perform another INSERT which also uses the value of this variable - however it doesn't appear to run correctly.

Does performing a SELECT INTO on an OUT parameter return from the procedure immedately? I am unable to find any information on this in the MySQL docs for SELECT INTO .

Answer 1

You can use the out-parameter within the procedure. Just check the syntax (and the function name):

Use syntax:

SELECT LAST_INSERT_ID() INTO p_AutoNumber;

Alternatively you can use syntax:

SET p_AutoNumber = LAST_INSERTID();
