RE: [MS_AccessPros] UNION query "Too Complex"

Robin,
That's what I was afraid of. I'm not sure why you break the table apart and then attempt to put it back together again.

You could just store values of folder names like "au/clubs/atoc/Albury/" with a title field in another table and build a totals query. Set the criteria under Page to
Like "*" & [Your Folder Name Field] & "*"

Group by [Your folder Title field].

This solution uses one extra table of data that puts maintenance where it belongs (in your table, not in code or expressions). You can add, remove, or edit records as you modify your website pages.

Don't work so hard. Life is too short.

They are analysis of pages counted from a website. All from the same table.

Each query counts pages visited in a given folder.

Two examples:

SELECT qStatsYTD.StatsID, qStatsYTD.Page, qStatsYTD.Visitors
FROM qStatsYTD
WHERE (((qStatsYTD.Page) Like "*.au/clubs/atoc/Albury/*"));

SELECT qStatsYTD.StatsID, qStatsYTD.Page, qStatsYTD.Visitors
FROM qStatsYTD
WHERE (((qStatsYTD.Page) Like "*.au/clubs/atoc/AlburyHume/*"));
