[GENERAL] Error size varchar
Hi!! I got error about a length field varchar. I have a table with a field type varchar(20) but if I try to set to this field more than 20 characters I got error. I did a function to control the length of data and put it on trigger but when it ocurrs I got the error anyway and the trigger not works. This error is over than trigger execution?? This is the error ERROR: value too long for type character varying(30) *---* *-Edwin Quijada *-Developer DataBase *-JQ Microsistemas *-809-747-2787 * Si deseas lograr cosas excepcionales debes de hacer cosas fuera de lo comun *---* _ Surf and talk on the phone at the same time with broadband Internet access.

The length constraint is checked before triggers are fired, I believe. If you want silent truncation rather than an error, use a text column (or unconstrained varchar) and put the truncation behavior into your trigger. regards, tom lane _ Fretting that your Hotmail account may expire because you forgot to sign in enough?

Then have a trigger truncate it after it is inserted. --- Adam Kavan --- [EMAIL PROTECTED] ---(end of broadcast)--- TIP 6: Have you searched our list archives? http://archives.postgresql.org
