Yes, I discovered that - "select max(num_attr)" does a full table scan even if the figure can be found easily through an index. There exists a workaround: select num_attr from my_table order by num_attr desc limit 1; will find the number through the index. -- Tobias Brox, Tallinn ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
