Re: Need to determine which version of a file a program has to work with

Normally I would use QUSLFLD API for that information. But since you're already in SQL, DESCRIBE may provide quicker result. (?)

All,

I've got a need for a program that can work on two different versions
of a file. Specifically, in one version of the file a particular
field is 10a, in the other it's 7p 0.

The program will be using SQL, so level checks aren't an issue. But I
still need to know which version I'm dealing with so I know which
statement to run.

We've come up with the following methods to determine which version of
the field is available
1) IBM API's
2) SQL Describe
3) Looking at SYSCOLUMNS

Any pros/cons to the above?

Does anybody have any additional ideas?

Thanks!
Charles
