Re: Index over join tables

This is what I call a index on a view, when used in RPG it acts like an indexed file that only sees some fields of the table.

In Loys sample he gets fields (columns) from two tables, but without an index.

Using DDS I can get a logical file (view) whit an index over two joined tables (psysical, all index fields must be from the same table), wich is what I need for this project, but I will prefer to do it in SQL, if possible.

Building an index over a simple view with SQL is something that's arrived with the current versions of i. CREATE INDEX myindex
ON mytable
(ColA, ColB desc)
WHERE recid='A'
RCDFMT (myindexR)
ADD (ColC, ColD)

But I don't think you can do that with joined tables.
