Re: Help solve an argument: Reading a SQL index in RPG?

In this case I would strongly recommend that RPG read the indexes. Why?
Because I have added columns to the underlying table and since the
existing indexes only select certain columns and not a 'SELECT *' the
underlying RPG doesn't get record format level check errors.

But the LF backing the index won't necessarily get the new columns
added. I don't know the exact pattern, but when you do an ALTER TABLE
to add a column to the table, the LF doesn't always get that column
added.

select * from rob.robmindex
ROBMINDEX in ROB not table, view, or physical file.

Yeah, that's my strongest physical argument ... but I'm looking for
something in the IBM docs that indicates WHY SQL won't let you do a
SELECT on an index.
