| Hi, the following statement worked on mysql but gives me an error on postgres: column "addresses.address1" must appear in the GROUP BY clause or be used in an aggregate function I guess I am doing something wrong. I read the web answers, but none of them seem to meet my needs: SELECT companies.id,companies.name,companies.organizationkind,addresses.address1,addresses.address2,addresses.city,addresses.zip FROM companies JOIN addresses_reference ON companies.id=addresses_reference.refid_companies LEFT JOIN addresses ON addresses_reference.refid_addresses=addresses.id GROUP BY companies.id; What I did now was create a view based on above statement but without grouping. This returns a list with non-distinct values for all companies that have more than one address, which is correct. But in some cases I only need one address and the problem is that I cannot use distinct. I wanted to have some way to display a companies list that only gives me the first stored addresses related, and disregard any further addresses. Is there any way to do this? Thanks Alex |
