I have 2 tables, identical in fields. One is an 'archived items' table, the
other is a live items.
I want to run a query that will grab the sum of all products in both tables,
like:
The results would display the total qty by item:
QTY NAME
The logic is something like:
sum(table1.qty) + sum(table2.qty)
The query that I came up with is:
select (sum(table1.qty) + sum(table2.qty)) as val,name from table1,table2
group by name order by val desc
It is just a bit off... (like 30000 off the actual count :) )
I have tried to do it with a where and group by clause, but no luck there
either...
Any suggestions?
- you've got a Cartesian results set because you haven't joined the
tables. Try joining on name, or writing two queries and then using a UNION.
