I have following SQL in a shell script to pick values from database
However, at times we need to take these value(s) from a variable. To do this we have following query.
Now I want to write this SQL such a way that it will check if the variable is null then it will pickup value from database, and if variable is not null then it will pick it from the variable.
Please guide me to do it efficiently as I got to do it for lacs of records.
Thanks
Anu.
