Re: SQL scripts in iNav -- MIDRANGE-L

× The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

Sounds like STRSQL isn't leaving the access path open, thus it can't reuse it.

Also, STRSQL's default optimization is FIRSTIO whereas Run SQL
Script's is ALLIO.

Which could make a difference in how the query engine choses to return
the results.

Add

OPTIMIZE FOR ALL ROWS to your green screen statement and see if it
works the same.

Hi

I'm running a select with group by, order by clauses. If I execute it on a greenscreen, it takes a few seconds and I see the message that an index is being created during the request. Each time. But with iNav, the subsequent executions are almost instantaneous. What's occurring?

Thanks
