Hello, I've encountered an unexpected behavior when converting a number to char. I need to match an INTEGER with a VARCHAR(9) that has leading zeros. When I tried to match them using to_char(num, '000000000') I didn't get anything. I later found out that to_char adds a leading space. This is demonstrated with the query below :
SELECT string, length(string), '"' || string || '"' AS showThemToMe FROM (SELECT to_char(42, '000000000') AS string) AS example; string | length | showthemtome ------------+--------+-------------- 000000042 | 10 | " 000000042" Is there a reason why to_char adds a leading space? Is this a bug? I can easily fix this with trim(leading ' ' from to_char(num, '000000000')), but, being of a curious nature, I'd like ton know why I need to do that. -- Samuel Gilbert -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
