What version are you running?

Can you give a test case of the first case (user_id='value' for
non-numeric value) with schema and sample data?  When
I try something like that on current sources I get 
"Bad numeric input format 'value'" for a numeric column.

The second looks okay (user_id=user_id) since the
value of the user_id column is going to be equal to itself
for any non NULL value in user_id. I don't know why you'd
expect that one to error.
