Re: Better SQL performance than SUBSTRING

Again, just a WAG, but I wonder if you need to explicitly name the indexed
substring. So...
(SUBSTRING(MY_COLUMN,5,6)) as KeySubstr

No idea where "AUXILIARY' came from.

That doesn't seem to work for me. The statement ran, but no object was
created.

Here's my statement:
create index MY_TABLE_SUBSTRING on table MY_TABLE
(SUBSTRING(MY_COLUMN,5,6))


Here's the message iACS gave me on the create:
SQL State: 01505
Vendor Code: 143
Message: [SQL0143] Statement CREATE INDEX AUXILIARY TABLE ignored. Cause .

Statement ran successfully, with warnings (6 ms)
