Need help in select statement from two tables
I have a problem in my select query statement to get the value of reject from op_reject table and spv_reject table in one row
here is my query:
SELECT o.compound_type, SUM(o.reject) AS op_reject, s.compound_type, SUM(s.reject) AS spv_reject FROM op_reject AS o ,spv_reject AS s WHERE o.compound_type = 'P28' AND s.compound_type = 'P28' AND o.process_id = '2' AND s.process_id = '2' AND o.reject_date = '2013-09-30' AND s.reject_date = '2013-09-30' GROUP BY o.compound_type, o.process_id;
but it should only be:
because the sum of rejects are only 3.00
I attached my database for your reference.
Any help is highly appreciated.
Thank you so much.

add one more condition o.compound_type = s.compound_type

Harsh is wrong. While it would be better in some abstract way to do
WHERE o.compound_type = s.compound_type AND s.compound_type = 'P28'Code:
WHERE o.compound_type = 'P28' AND s.compound_type = 'P28'
To find the problem, please use this query and show us the results:
SELECT o.compound_type AS otype, o.reject AS oreject, s.compound_type AS stype, s.reject AS sreject FROM op_reject AS o ,spv_reject AS s WHERE o.compound_type = 'P28' AND s.compound_type = 'P28' AND o.process_id = '2' AND s.process_id = '2' AND o.reject_date = '2013-09-30' AND s.reject_date = '2013-09-30' ;An optimist sees the glass as half full.
