Subj:   Re: Field update running slowly
 
From:   DWellman

Hi Paul,

Yes, that sounds like a long time.

I think it's "back to basics" time:

- is the table evenly distributed across the AMPs ?

- are their any indexes on this column ?

- is this table perm journalled ?

- how busy is the system at the time it's running ?


I guess that you've changed the sql code to remove the tablename (that's fine), is the rest of the code 'real' ? No WHERE clauses removed - i.e. you're updating the entire table.

Double check that the table really only has 180k rows in it.


Regards,

Dave
