hi list,

student_id | tally | org_id
--------------+------------------
1 | 0 | 1
2 | 0 | 1
3 | 0 | 1
4 | 0 | 1
5 | 0 | 1
1 |8367220 | 2
3 |7561391 | 2
5 |2207271 | 2
4 |1280995 | 2
2 |1265355 | 2

and i want to lay the table like this:

student_id | 1 | 2
--------------+--------+--------
1 | 0 | 8367220
2 | 0 | 1265355
3 | 0 | 7561391
4 | 0 | 1280995
5 | 0 | 2207271

crosstabs?
