does one of the variable contains NULL?

if i comment the if statement, it will run.
so your statement does not run when @UserId = 0?
This is because you are concatenating a NULL with a string and the NULL is propagating (turning everything to NULL).
Are you trying to send a NULL to your SP?

Null to be inserted in the table column. I am passing it in the INSERT statement.
