Giovanni writes "I am using the COALESCE function in my SQL stored proc. This makes for a small WHERE caluse and all is well except under the following condition:
I use o.SL = COALESCE(@_SLParameter, o.SL)
The problem is when the o.SL table field value is itself a NULL. I DO NOT want to eliminate it from the resultset. I want to bring it back. In other words, if the paramter is NULL, take all records from the o table including the NULL one's. What can I do." |
