Re: SQL created table slows reporting tool

i beleive they have an option 'group on server' at any rate we have been
much better since we switched to Views on the i rather than the ad hoc
crystal sql. The issue here is
we have a new data warehouse file which is very large and has no indexing.

Actually I'm not saying that you have to make either a stored proc or
LFs or views.

You do need to be sure that you tell Crystal to run the query on the
server, not at the PC. Crystal at least used to, by default, run all
queries on the PC, which means that the entire table had to be
downloaded from the server, then the query is run against that "full" copy.

I like the idea of using a view - to limit the columns downloaded - and
maybe the rows, due to selection. You will still benefit from making the
query be run on the server, then downloading only the results. I think
this is especially the case, because you will likely not want to make a
view for each WHERE possibility - so if your Crystal report has
parameters for selection, again, you need to run the query on the server
- it's a setting somewhere in Crystal, last I saw, which is years ago!

in this case i was just taking a peek at the raw table. So it seems that
what you are saying is we have to make either stored proc or

logical/views

on the Ibm i. this is fine, This is what we currently do on the dds based
PF's.

Is the out-of-memory condition on the PC or on the IBM i?

In any case, be sure to set CR to have the SELECT done on the server,
that is, on the IBM i - NOT on the PC - in the latter case, the entire
file has to be downloaded, THEN the query is run against it. Bad Bad

Bad!!

There are other confusing things about this question, but I'll leave my
questions to what I asked already.
