Re: DDS altseq keyword function for SQL create index - Solved

Vern,

Tres cool, Dave. We're just beginning to think around here that this can be pretty useful. I've not confirmed it, but maybe, In SQL, if, when the sort sequence for SQL is *LANGIDSHR, there is an ORDER BY on the indexed column, then the optimizer might actually use this index, instead of a sort or temporary index on its own.

Don't know if this is true or not.

Now in RPG, as you are doing, does the data come back untranslated - i.e., in its original case?. I'm thinking it should, as the actual records of the PF are not changed.

Yes, everything gets returned to the program in its original case. Same results when I use Ezview on the logical.

I had some additional problems because of the way I handle the subfile. I read the records into an array and then sort the array in the sequence the user wants, then load the subfile from the array. When I sorted the array on description, it would mess up the mixed case sequence. After I added the AltSeq(*Ext) and SrtSeq(*LangIDShr) to the H specs, the sorta command sorted the mixed case fields together.

Thanks again for the help.
