Re: [GENERAL] LIKE problem
2009/7/6 Juan Pablo Cook juamp...@gmail.com: Hi Everybody! I'm asking you, because recently I have some problems with the LIKE so I test with an easy and simple query but doesn't work: SELECT * FROM employee WHERE id like 'h%'; The error says: ERROR: operator does not exist: integer ~~ unknown SELECT * FROM employee WHERE name like 'h%'; -- there are not LIKE operator for integer values. you cannot use LIKE on integer columns regards Pavel LINE 5: WHERE id like 'h%'; ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. ** Error ** ERROR: operator does not exist: integer ~~ unknown SQL state: 42883 Hint: No operator matches the given name and argument type(s). You might need to add explicit type casts. Character: 34 I don't know why because I did before more difficult querys and works well. What is the problem?

Re: [GENERAL] LIKE problem
In response to Juan Pablo Cook : Hi Everybody! I'm asking you, because recently I have some problems with the LIKE so I test with an easy and simple query but doesn't work: SELECT * FROM employee WHERE id like 'h%'; The error says: ERROR: operator does not exist: integer ~~ unknown LINE 5: WHERE id like 'h%'; ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. You can't compare a INT with a TEXT: test=*# select '1'::int4 like '1'::text; ERROR: operator does not exist: integer ~~ text LINE 1: select '1'::int4 like '1'::text; ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. But you can CAST the INT into a TEXT: test=# select '1'::int4::text like '1%'::text; ?column? -- t (1 row) Okay? But in your case,you have an INT-column (id) and you compare that with 'h%'. You can CAST the id-column, but all INT::TEXT don't match 'h%'. -- Andreas Kretschmer Kontakt: Heynitz: 035242/47150, D1: 0160/7141639 (mehr: - Header) GnuPG-ID: 0x3FFF606C, privat 0x7F4584DA http://wwwkeys.de.pgp.net -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
