What's the exact error message and what version of PostgreSQL are you running? At least three things could be contributing to the error: 1. The syntax for altering a column's type is ALTER [ COLUMN ] column TYPE type [ USING expression ] The command you showed is missing the word "TYPE". 2. Altering a column's type is supported only in PostgreSQL 8.0 and later; if you're using 7.4 or earlier then you'll need to perform the steps shown in the FAQ: http://www.postgresql.org/docs/faqs.FAQ.html#item4.3 3. PostgreSQL doesn't have a builtin varchar2 type. Unless you've added varchar2 then use varchar instead. Try this: ALTER TABLE lugar ALTER COLUMN sitio TYPE varchar(500); -- Michael Fuhr ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
