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;
this code has an output:
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.
