Обсуждение: BUG #4091: ECPG $select incompability with Informix
The following bug has been logged online: Bug reference: 4091 Logged by: Mikael Omma Email address: mikael.omma@ge.com PostgreSQL version: 8.2.6 Operating system: SUSE Linux 10 Description: ECPG $select incompability with Informix Details: ECPG "$select a, b, c into :a, :b, :c from table". If in the db table the order of columns (b, a, c) this will not work. I have ESQL code from Informix ported to PostgreSQL. In informix the order in columns in the select query does not have to match the real order in the table of the database. Workaround is to reorder all columns in the ported code.

You must be doing something else wrong, but we can't tell because you didn't show us enough details. Try what you want in psql and you will see it works. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + If your life is a hard drive, Christ can be your backup. +
