Re: Converting Case with a Varying Field

I didn't catch what version of the OS you are on. But starting in
V6R1 you could create derived keyed indexes. i.e.

*CREATE INDEX* X1 *ON* T1 ( UPPER(COL1) )

As I understand it. If you were to write a query like so...

select * from T1 where COL1 = UPPER(:HostVar)

Then it would use the index created.


As I understood, the query would have to use the identical expression [to the one in the INDEX] to enable the derived index to be chosen for implementation of the query; i.e.:

select * from T1 where UPPER(:HostVar) = UPPER(COL1)
