Data type mismatch in critia expression when sorting

I am trying to sort the TTLotID field, but I get the data type mismatch error.  Why is that and how can I fix it?


SELECT CLng(Replace([Litho Data].[TTLotID],"-","")) AS LotID
FROM [Litho Data];

Probably due to Null values. Try:

SELECT CLng(Replace(Nz([Litho Data].[TTLotID],"0"),"-","")) AS LotID
FROM [Litho Data];

NO.  It still has the same error.

You say you were trying to sort by the TTLotID field - I assume you mean you were trying to sort by the new LotID field?

Try this:

SELECT Clng("0" & Replace([Litho Data].[TTLotID],"-","")) AS LotID
FROM [Litho Data];

or better:

SELECT VAL("0" & Replace([Litho Data].[TTLotID],"-","")) AS LotID
FROM [Litho Data];

Is [TTLotID] in the table [Litho Date] a text field?

I presume the value of TTLotID after the replace is less than 2,147,483,647.  That is the largest positive integer CLng will support.
