I have a table:
id | priority | seniority
-----+----------+-----------902 | 2 | 271902 | 1 | 271902 | 3 | 271924 |
2| 581924 | 1 | 581924 | 3 | 581935 | 1 | 276935 | 2 | 276972
| 2 | 275
(9 rows)
I'd need to get a result set where rows are sorted according to these rules:
1. first all rows with priority = 1 sorted according to seniority
2. then the rest of the rows sorted by seniority, priority
Something like this:
SELECT * from foo where priority = 1 order by seniority union select * from foo where priority > 1 order by
seniority,priority
but this gives parse error because of the restrictions with ORDER BY and
UNION (I suppose..)
select * from foo order by case when priority = 1 then priority else
seniority end;
goes fine, but it's not quite enough and when I try
select * from foo order by case when priority = 1 then priority else
seniority, priority end;
it's parse error at or near ",".
Any suggestions?
Thanks in advance,
Timo

CREATE TABLE foo ( id integer, priority integer, seniority integer
);
INSERT INTO foo VALUES (902, 2, 271);
INSERT INTO foo VALUES (902, 1, 271);
INSERT INTO foo VALUES (902, 3, 271);
INSERT INTO foo VALUES (924, 2, 581);
INSERT INTO foo VALUES (924, 1, 581);
INSERT INTO foo VALUES (924, 3, 581);
INSERT INTO foo VALUES (935, 1, 276);
INSERT INTO foo VALUES (935, 2, 276);
INSERT INTO foo VALUES (972, 2, 275);
