Hi! Data type of table1.c1 is bytea. That column stores binary data. The following matchings do not work. What is the right syntax? TIA CN --------------- select c1 ~ E'\000' from table1; select c1 LIKE E'%\000%' from table1; ERROR: invalid byte sequence for encoding "UTF8": 0x00 HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding". -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
