Smith" <ship.quo...@gmail.com> Date: Fri, May 13, 2011 12:00 pm Subject: [SQL] Sorting data based fields in two linked tables To: <pgsql-sql@postgresql.org> Hi, I am looking for a way to sort data returned from two tables with the first sort based on a field from table A and the secord sort based on the results of the first sort but the sort field is from table B. While I can sort on either fields from either table, I cannot get it to work on both. I have tried a crosstab query, but this a fails as the number of rows returned from TABLE B for each row in TABLE A is an unknown. I tried creating a temporary table, to then sort on, but this failed as well. Example layout below: Table A ID FIELD1 FIELD2 Table B ID, A.ID FIELD1,FIELD2 Output Based on sorting A.FIELD2, then B.FIELD1 A.ID,A.FIELD1,A.FIELD2, B.FIELD1,B.FIELD2, B.FIELD1,B.FIELD2, B.FIELD1,B.FIELD2 Can anyone help me with this?
