It will never use both.
Usually the first index command possible will be used.
Although I believe an EQ will override an index with GE.

Hi Barry
The first question with sql is - which sql? There are lots of variants, all
offering very different capabilities and features (like U2 vs R83). SQL*Plus
for Oracle is very different from TSQL for SQL Server: SQLite is a very
'standard' SQL but almost nobody uses the ANSI syntax to that
From the Using UniData manual:
Alternate Indexes in UniQuery Statement
Prior to UniData 5.2, only one index was used in the selection criteria of a
UniQuery statement, even if the selection criteria contained more than one
indexed attribute. UniQuery now uses all available indexes when
Am not sure why you would be getting the last hashed dictionary item passed.
However, I think you would need to pass something other than @ID to your
subroutine - a multivalue of files via another I descriptor with subroutine.
Don't know about in UniData but in UniVerse VOC4 has M and 7 an mv
Excellent news.
However, is there a way to utilize two indexes with the SELECTINDEX
command in Unibasic?

It turns out that UD works this way. The solution was to also pass in

correct VOC item. So, I was able to read attribute #2 (the data file

You just add the keyword EXPLAIN to the end of your query statement.

You might try to re-compile the code. Ever since I went to UniData on

The difference may depend on the UNIX LANG setting for different users.
LANG=C may be required. You don't say what platform you are on.
We may also have fixed something since 6.1.15. My memory isn't what it used to
be. You can certainly scan the readmes for MCU and/or UPCASE.
