Re: AW: if defined syntax in sql rpg?

["Brian Parkins" <PARKIB@xxxxxxxxxx>]

The SQLDA (Descriptor Area) is only required when Dynamic Embedded SQL is
being used to perform a Varying-List SELECT.  In other words, only if the
list of SELECTed columns or the FROM table(s) are unknown at (pre-)compile
time.

For all other types of embedded SQL: Static, Dynamic non-SELECT and Dynamic
Fixed-List SELECT the SQLDA is not necessary.

Hi James,

the SQLStmt can be varying.
You have to use the SQLDA.

We've build a procedure and we use it in this way

eval statement = ......

dow sql_statement(statement)
eval filexyz_ds = sqldata_ds
...
enddo

Does SQLStmt have to be varying?  I'm on V4R1M0 and last I checked I
couldn't use varying.
