>select * from table order by flag desc, contract, master

The problem with that is that he'll get all the masters up front. I think
he's looking for a result set that has the master followed immediately by
its children.

Assuming that the "blank" master ids are null:

select * from c order by coalesce(master, contract), Flag desc, contract

Would provide the requested result. The coalesce function return the first
non-null function. So for the master contracts where master is null it will
return contract for the child contracts it will return master.

I have a file that has  a contract#, a flag that indicates if the file
is a master contract, and a master contract#
so i might have something like

contract    flag    master
1                y
2                y
3                n        1
4                n        2
5                n        1


where contract 1 is a master contract with subordinate contracts 3 and 5

i'm trying to create an SQL statement that will list the master
contracts and the subordinate contracts. So far i haven't been able to
get this to work.  Can i do this in 1 statement.

i want results such as


contract    flag    master
1                y
3                n        1
5                n        1
2                y
4                n        2
