Speeding up reports

Speeding up reports

Speeding up reports

(OP)
I have a program which contains archive information in 4 tables.  This information can go back some years.  These tables are linked together via indexes, set relation, and filtering (mainly date ranges).  Using these tables different reports are available.  Problem I have they can take some time to run.  I believe this to be mainly due to the amount of data stored and due to the fact that the reports are usually completed over the network on a slave machine.  Is there some way I can spead these up??

I've never used SQL.  This this used to speed things up???  Sorry for my ignorance.

RE: Speeding up reports

By filtering, do you mean you are using: SET FILTER TO Expression ?

Filtering in this way is known to be slow. You can use indexes to filter instead.

Creating a temporary (SQL) cursor to show your data could be an option. If it is faster, I wouldn't know, you'll have to test that (depending on your machine, network speed etc.).
The advantage is that you can filter out data that is not necessary and you can store all info in one cursor, without having to set relations etc.

Good luck,

HTH,
