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.


Just a thought/suggestion.

Not 100 million, but potentially several thousand while the user is waiting
for their screen to come back. (I'm implementing an "ignore case" option
for
an app where the user types in a string and then gets a list of all records
that contain that string
"anywhere". There may be several thousand records in the main database,
plus
each record may have more in associated databases -- notes, etc. -- so
there's likely to be a dozen or more searches per main record. But maybe
that's nothing to the i? :-)

Not necessarily - are you doing this over 100 million records? Or
onesy-twosy?

The real code just sets a host variable going in, calls a program to
convert it, then sets the host variable back again - nothing much. The
stuff we'd write could easily be more complex than is done in the called
SQL program.
