Well, if you don't care, this might give you what you want. select distinct on (x.first6) crm.*, x.* from from sap_crm_sales crm join (select left(mc.sap_code,6) as first6, mc.* from model_configurations mc) x on x.first6 = left(crm.customer_class, 6) order by x.first6; I can think of about a dozen different things which fit the description that you've given so far that you *might* want instead, but unless you get more specific we can only guess. If this isn't what you want, your best bet might might be to come up with a self-contained example, where you create an populate tables with a small amount of data, and show what you would like as a result given that data set. -- Kevin Grittner EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
