Re: sqlplus instead of PRO*C for simple DB queries from C?

I don't think anyone could quarrel about this approach with the facts as simple as you describe... I have done simular things via a UNIX script which generated the appropriate script, executed it, called the program to process the generated data then deleted the data file and the SQL script file(to avoid eatting up disk space).

The bonus is that It would be very easy to maintain...Especially if you don't have "C" folks on staff.
