SELECT * from table_name WHERE (c1=c2) AND (c2=c3) ORDER BY c4;
will work, I think:
===================
test=> CREATE TABLE joost (c1 varchar(10), c2 varchar(10), c3 varchar(10),
c4 varchar(10));
CREATE TABLE
test=> INSERT INTO joost VALUES ('test1','test1','test1','remark');
INSERT 1179458 1
test=> INSERT INTO joost VALUES ('test1','test1','test1','remark2');
INSERT 1179459 1
test=> INSERT INTO joost VALUES ('test1','test2','test3','nevermind');
INSERT 1179460 1
test=> SELECT * from joost ;
c1 | c2 | c3 | c4
- -------+-------+-------+-----------
test1 | test1 | test1 | remark
test1 | test1 | test1 | remark2
test1 | test2 | test3 | nevermind
(3 rows)
test=> SELECT * from joost WHERE (c1=c2) AND (c2=c3) ORDER BY c4
test-> ;
c1 | c2 | c3 | c4
- -------+-------+-------+--------
test1 | test1 | test1 | remark
test1 | test1 | test1 | remark
(2 rows)
