RE: CREATE INDEX and name only some columns

Well, no....  yes... maybe!

One thing to remember about SQL is that views and indexes are completely independent of each other.  When you USE a view, SQL may make use of an index to order the result, but the index is ALWAYS over the base PF, never anything else.  

When you create an index in OS400, a side effect of this architecture is that the index behaves just like a keyed logical that does not select columns.

Create both your view AND the index, and when using SQL, it will put the two parts together for you....

Subject: CREATE INDEX and name only some columns


Can I create an SQL index and name the columns so that I'm only including
specific columns from the base table instead of all columns?

Or do I need to create a view, and then an index over the view (because a
view can't have a 'key')?

I've been looking for examples creating an index with specific columns,
haven't found any, and therefore I think I can't do it.

Thanks.
