Huston we have a problem:
table1:
purchase_order (primary key)
client_number
buyer_name
table2:
client_number
buyer_number
buyer_name
(all three combine for the primary key for table2)
Query:
select table1.purchase_order, table1.buyer_name,
table2.buyer_number from
table1 inner join table1 on
(table1.buyer_name = table2.buyer_name);
This works, it takes 4 seconds with a limit 50...
but there is over 100,000 records in table1 and over 33,000 records
in table2, so the inner join has to create a temp table with 100,000
X 33,000 records(??? is this right) to do it. = 133mins.
Any info, pointers would be apreciated. Thanks
