Question

I have the following tables:

ALERT (ID,Name)    1  |  Alert A    2  |  Alert B   ALERT_BRAND_XREF (ALERT_ID, BRAND_ID)    1  | 1    1  | 2    2  | 1  BRAND (ID, NAME)   1  | Brand A   2  | Brand B 

I am trying to write one statement to return a list of alerts with the applicable brands as a CSV list in one field. Desired results:

 Alert A  |  Brand A, Brand B  Alert B  |  Brand A 

Is there a way to do this without writing a separate function? I would like to do it in one self-contained SQL statement if possible.

This is Oracle 9i.

Answer 1

In MySQL this would be easy with the GROUP_CONCAT() function, but it looks like to do the equivalent in Oracle it’s a little messy:
