Re: [MS_AccessPros] MAXIMUM NUMBER OF CRITERIA IN MSACCESS QUERY

Thanks John and Duanne. I found a way out . I reduced the number of criteria to run the first query. I then did a make table query from this first query.

Lastly I ran a second query on the table thus created with my remaining criteria .

I think this might work for those who have challenges of having so many criteria in their queries.

It's not the number of columns, it's the complexity of the SQL. The query engine "compiles" your query into something like a 64K "workspace", and if the compile won't fit in that, you'll get query too complex. A very complex WHERE clause is often the culprit.

Can you share the SQL view? Have you declared the data type of your criteria?

Please can someone assist. I was running a query with many criteria (very well in excess of 60) and the system came back with a message that 'Query is too complex' I thought I could go as far as 255 columns .

Thanks.
