Question

My problem is the following..

The help that I need is to only SELECT when both prp_response <> 1 for each of prp_hist_id
so it will list those ones (DISTINCT)

For example in this case will only SELECT only the prp_hist_id = 21 since both prp_response <> 1

Hope I was clear enough and any help would be greatly appreciated. Thank you.

Answer 1

SELECT DISTINCT prp_hist_id
FROM tbl_proposal_workload
WHERE prp_hist_id NOT IN ( SELECT prp_hist_id FROM tbl_proposal_workload WHERE prp_response = 1 )
