Hi,
I have a workflow with an SQL query as an input that returns about 50,000 records.
The results have 2 'Conv Errors' as below - I would like to modify the query so that values like this are automatically replaced with blanks/nulls (I know these errors are nothing to worry about but someone else may not).

I have tried replacing 'date_inv_u' in the SQL statement with the below:
...,Case date_inv_u When '0001-01-01 00:00:00' Then '' Else date_inv_u End As date_inv_u_test,...
The workflow runs without any errors, but the results are odd. See below. What am I doing wrong?
