Here's a puzzler:
Given a query that returns rows ranked by some criteria, how can I write
another query around it that will give me the (say) first quartile (top
25%)? Another way of putting it is: if I have rows that look like this:
aaa | 1251
aba | 1197
cax | 1042
... | ...
axq | 23
(142 rows)
How can I write a query that will return these as
1 | aaa | 1251 2 | aba | 1197 3 | cax | 1042
... | ... | ...
142 | axq | 23
