RE: Logical File version of Distinct?

["DeLong, Eric" <EDeLong@xxxxxxxxxxxxxxx>]

You can use "create view" in SQL to build a LF that returns distinct
results, and it can be used in RPG.  However, you cannot specify a key for
this LF, and performance really sucks if the source data has many rows.  Try
it out and see if it works for you....

Subject: Logical File version of Distinct?


If I use sql, I can use the distict keyword, to get only one record from a
similar group of records... Is this possible by using a DDS Logical file?
and then only use read or reade in a RPG program?

Just wondering...  I know I can embed the SQL statement in the RPG, but I
was trying to avoid it, unless I have to..

Thanks, tim
