sql - Arrange my result in select query of postgresql? -

-

i have query:

select c1,q1,c2,q2,c3,q3,c4,q4 mxm

the result is:

c1    q1   c2     q2    c3     q3    c4      q4    9103  4    9114   3.3   9197   1.9   b9151   3000  9103  15   9107   8.6   9118   8.3   b9100   130.6 9103  3.6  9114   0.6   9197   1.1   b9151   5000

but want output like:

9103  4 9114  3.3    9197  1.9    b9151 3000  9103   15    9107   8.6    9118   8.3    b9100  130.6

and on .... possible in postgresql?

if want them in order, bit tricky. assuming have no appropriate id in mxm identifying rows in order:

with t (       select row_number() on (order ??) seqnum, mxm.*       mxm ) select c, q ((select c1, q1, seqnum, 1 ordering t) union       (select c2, q2, seqnum, 2 t) union       (select c3, q3, seqnum, 3 t) union       (select c4, q4, seqnum, 4 t)      ) cq order seqnum, ordering;

the ?? column specifies original ordering records.
