Обсуждение: DELETE FROM error message
When running the following DELETE FROM in psql,
omni=# DELETE FROM inventory WHERE invid = '01044T';
ERROR: Unable to identify an operator '=' for types 'varchar' and 'bpchar'
You will have to retype this query using an explicit cast
I receive the above error message. The field "invid" is a bpchar.
TIA,

You will need to cats '01044T' to bpchar since postgres will take any string as a varchar unless specified otherwise.

I tried your suggestion (both ways), but I still get the same error message about explicit casts.

FYI, I don't get that error message when I SELECT. For instance: SELECT * FROM inventory WHERE invid = '01044T'; works just fine with no errors. When I try to delete that same record, I get the error about explicit casts.
