Dejan"If you fire x% of your staff to realize y% productivity gains, then firing all your staff should give you infinite productivity assuming geometrically progressive rising gains..."01:44

Dejanguys, do i have to re-create table if i want to change to NODUPLICATES ?08:36
PaulM05no just re-modify08:37
PaulM05assuming that you're removed duplicates of course ;)08:37
Dejanwhat i get is: E_PS0BC6 MODIFY: Line 1, duplicates is not a valid option for WITH clause.08:38
Dejanmodify tablename to reconstruct with duplicates;\g08:39
Dejanthat is what i tried08:39
Dejanalso modify tablename to hash on column with duplicates;\g08:39
Dejansame error08:39

PaulM05looks like you do need to re-create the table08:57
Dejanyep09:03
Dejanthat is why i asked if i have to re-create it09:03
PaulM05well I thought you could do it with a modify but I was wrong09:04

Dejani need to change couple of hundreds of tables...09:10
Dejanfrom DUPLICATES to NODUPLICATES...09:10
*** Mud has joined #ingres09:13
PaulM05[NO]DUPLICATES applies across the whole row - it might be easier to make the table structure unique on whatever key09:14
Dejanwhat you mean by "applies across the whole row" ?09:16
PaulM05I mean that creating a table with NODUPLICATES means the entire row must be unique.09:18
PaulM05as opposed to say BTREE UNIQUE on col1,col2 etc09:18
PaulM05but a unique key implies you can't have a duplicate row09:19
Dejanaha, the point is - they made many tables without any keys...09:19
Dejanbut some of those tables must be NODUPLICATE09:20
Dejanbecause we should not allow duplicate rows in them09:20
Dejanand they do not have duplicates09:20
Dejanit is a legacy databases I want to ... "fix"09:20
Dejansimply by doing simple modifications09:21
PaulM05well you'll need a key to enforce the uniqueness - a heap table always allows duplicates09:21
Dejanyeah, i read about that09:21
PaulM05anyway - I'm away home - bye09:41
