DECODE FUNCTION

[dshaw21369]

Hi,
Can you call a procedure when returning value using the DECODE function?

Dshaw,

I'm not certain what your question means, so if you can clarify, that would be helpful. I can tell you that PL/SQL does not support the DECODE function directly. If you want to use DECODE withing PL/SQL, it must be within a straight SQL statement within PL/SQL, otherwise you receive a pass-1 interpreter error.

I'm happy to share more if you can clarify your question.

You can use functions quite freely with DECODE. But performance is another chapter, especially when using aggregatefunctions like SUM,...

I guess I'm trying to ask, can you call a procedure from the DECODE function.

DECODE is a function used in an SQL statement. A DECODE cannot call a stored procedure; however, it can use another function as one or more of it's parameters. Example:

select decode(COL1,'X','Y',MY_FUNCTION(COL1))
from   MY_TABLE
