You can define the order of the fields in the SELECT-Statement. Other way: you can create a VIEW. And another way: you can recreate the table (create new_table as select <cols in desired order> from old_table, drop old_table, rename new_tabel to old_table) Andreas -- Andreas Kretschmer Kontakt: Heynitz: 035242/47150, D1: 0160/7141639 (mehr: -> Header) GnuPG-ID: 0x3FFF606C, privat 0x7F4584DA http://wwwkeys.de.pgp.net ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org |

| I understant you inquiry but I don't meant to add all the fields order in an insert statement. IE: insert into table values (value1, value2, value3....) is better than insert into table (column1,column2,column3 ...) values (value1, value2, value3....) If there is only one way (recreating) that was not good for me. Regards Ezequias 2007/2/27, A.

No, it isn't better, because, if you change the table in the future and add new colums, your insert-statement will be failed. If you write your insert with explicit column order, nothing happens, except the new row will be empty.
