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?
Regards
