Database unresponsive Upload Images   Link   Email  
Jeff Bartuch 
I have a large database (400,000-500,000) rows of data. I added Currentdb.Execute code to handle my action queries. All of the tables are local to that database. I noticed my database goes not responsive while trying to run these queries. Is that normal for to the amount of the data being appended or updated?
Kevin Yip
What is the amount of data being appended or updated?  You only mentioned the size of your tables, which does not necessarily cause delays.  It is the number of rows (and fields) that EACH query tries to update that affects performance, and good query design always tries to minimize that.  If one of your queries tries to update 400k rows in one go, then there will definitely be a delay.  But if it updates only 10 to 50 rows in a 500k-row table, it should be instantaneous.

Try switching to RunSQL. You'll be able to see the little status bar indicator telling you it's running. That will at least give you an indication of whether or not it's working.

The tables I'm importing are roughly the same size, (400,000-500,000).

I know it's working. It just goes unresponsive and the screen turns white while doing so.. I know it's going through a lot of data.

I just tried importing a 570k-row table from one Access DB to another (External Data -> New Data Source -> From database -> Access) and it was instantaneous.  Try this method instead of action queries.  The import wizard in Access can import many data formats so you may not need to use queries to do it.
Jeff Bartuch
Instantaneous? That's awesome!
