I have a complex query question whose answer I think would help me to understand subselects and aggregates better. I have a table with four columns of interest:
id (int primary key), loc_title (varchar null), loc_value (float null), loc_unit (varchar null) I want the output columns to be: (1) each distinct value of loc_title, sorted (2) an id of a record containing that loc_title (3) the loc_value for the record in column 2 (4) the loc_unit for the record in column 2 I don't care as much how the records for columns 2-4 are chosen. It could be max(loc_value), min(id), or something else. I just need some sample records to test my program against. Is this something I should be able to do with a single query with a subselect, or is it too much for one query? I tried a few ways and none of them were syntactically valid. -- Mike Orr <sluggos...@gmail.com> -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
