Data Type Mismatch - Concatenated Field

[Harry F.]

Hello,

I have concatenated two fields, both of the Text Data type. When I do an
unmatched query to check this concatenated field in two recordsets, the
expected results come up for a few seconds, at which point I get the infamous
"Data Type Mismatch in Criteria Expression" error, and all of the data in the
query turns to #Name?

What is going on here?

TIA,
Harry

Could be nulls:

Debug.Print "ABC" & Null returns ABC

Debug.Print "ABC" + Null returns Null

Then there's the possibility of a corruption issue. Try a compact and repair.

Hi Jerry,

Thank you for the reply. Compacted and repaired, and that didn't help
(Also this DB is a week old with very little data in it so corruption is
unlikely).

Can you expand a bit on the nulls - how can I dance around this - should i
query the two record sets and eliminate nulls before comparing?

Thanks,
Harry

Post the SQL where you do the compare.

You might try wrapping both field with the Nz function in the concatenation

Concat: Nz(FirstField,"") & Nz(SecondField,"")

This just caused the Data Type Mismatch error to appear before the query
finished running.

Here's the SQL...


SELECT qryNewAccountsReconciliation1.cconsol,
qryNewAccountsReconciliation1.Screen, qryNewAccountsReconciliation1.Field,
qryNewAccountsReconciliation1.Xref, qryNewAccountsReconciliation1.Value,
qryNewAccountsReconciliation1.[Changed From],
qryNewAccountsReconciliation1.[Changed To],
qryNewAccountsReconciliation1.[Changed By],
qryNewAccountsReconciliation1.[Changed At],
qryNewAccountsReconciliation1.[Account Name],
qryNewAccountsReconciliation1.[AW Reference]
FROM qryFulfilledNewAccounts RIGHT JOIN qryNewAccountsReconciliation1 ON
qryFulfilledNewAccounts.xrefpair = qryNewAccountsReconciliation1.xrefpair
WHERE (((qryFulfilledNewAccounts.xrefpair) Is Null));

Thanks,
Harry
