that looks like EAV. is it? > I=B4m trying to do an update like this: that's not going to work. perhaps you can rewrite the from part to only return one row for every table1_fk, this one row will combine several rows from table2 > The "FROM ( SELECT * FROM table2 ORDER BY id ) tHist" is a try to > force a specific order on table2 to update table1 > but this isn=B4t working. will only work if the optimiser picks index join on table 1 > There are some way to do this with a UPDATE statement ? to do it with an update statement you need no more than one rows in the from for each row in the target. easiest non update statement approach is probably to use a plpgsql function with a loop. basically you need to find another way to do it. -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
