Hello All:

About a dozen users are independently updating separate Access tables
in the same db. The following Excel front end code is designed to
return the list of tables that are then passed to a SQL command that
runs three functions: Count, Sum and Max to determine the row counts,
when the table was updated, etc.

The code works fine with only one function, but it crashes at the
recordset open command when two or more functions are called resulting
in a "...Run-time error...(80040e14) is not a valid name. Make sure
that is does not include invalid characters or punctuation and that it
is not too long".

Thanks for any help.

Hi

I've never har problems with that. And the only thing you seem to do different from what I usually do is
- square brackets around SQL statement,
- "adCmdStoredProc", and missing
Set rst = Nothing
Set cnn = nothing
at the very end.

Consider also a global connection that stays open during the repeating loop, instead of a new cnn each time. It's a little faster
and should also be more stable. It's impossible for me to test your code as is, so this is just guessing. And I may well be
overlooking something important.

Want a incredibly faster way to paste the results btw ?

Sheets(outputsheet).Cells(2, 1).CopyFromRecordset rst
rst.Close

No looping, simply that.
