Report for week 1: Hello!
I made test cases and extended the parser for: INSERT...RETURNING * and INSERT...RETURNING <col_name/names> It is working fine for INSERT...ON DUPLICATE KEY UPDATE, INSERT...IGNORE, INSERT...SET, and simple insert statements. As I have never coded parser before, it was throwing errors during build and was also crashing the server sometimes. I managed to fix the errors eventually. Initially, I tried to extend <column_names> in RETURNING by referring how column names are parsed in INSERT statement, like using opt_fields production for insert_field_list, modified it a little and tried to see it if that would work. But it didn't. So I referred to DELETE...RETURNING as it was suggested earlier. I am still trying to extend it for INSERT...SELECT. It is not showing syntax error but shows error "column count doesn't match value count at row 1." I will add the test cases for this once it is working. Regards, Rucha
