Got it to work perfectly, thanks, although it takes some time (CILS has >150.000 records). There was no need for unique since all the results are already surprisingly unique.
Thank you, it was a different way of doing things. Well, different to me, at least. :-) In the meantime, i found an alternative way of doing things, although honestly i think its a bit "dirty" (prod_enc is JOB, prod_enc_cil is CILS): select t1.num_of from (select pe.num_of,GROUP_CONCAT(cast(pec.id_cor as char) ORDER BY pec.id_cor DESC SEPARATOR '|') cores from prod_enc pe join(prod_enc_cil pec) on(pe.num_of=pec.num_of) group by pe.num_of order by pe.num_of desc) t1 where cores like '%cyan%magenta%' I cant get it to work if i only keep the inner select: select pe.num_of,GROUP_CONCAT(cast(pec.id_cor as char) ORDER BY pec.id_cor DESC SEPARATOR '|') cores from prod_enc pe join(prod_enc_cil pec) on(pe.num_of=pec.num_of) group by pe.num_of order by pe.num_of desc where cores like '%cyan%magenta%' Like this it complains about not having a column called "cores", which i find very weird. Any insight on that? And yet another way, although it results in a different record count. How can it be possible? select num_of, count(num_of) c from prod_enc_cil where id_cor='cyan' or id_cor='magenta' group by num_of having c>1 order by num_of desc What this does is list all CILS that have cyan or magenta, and shows the num_of that are doubled (thus have both colors).
