Hi guys,
If I have a table that is just a single column full of numbers, how can
I select all the rows from the table with a second column that is the
running tally so far down the result set?
eg:
Num Tally so far
0.3 0.3
1.2 1.5
2.0 3.5
...
Does this require PL/PgSQL coding? If so, how do you actually construct
an arbitrary row for returning? The docs are somewhat unclear on this.
Chris
