Possible bug when running functions like SUM on Windows 2008 R2 (1 reply)

Hi

I have found problems when trying to run VB.net interloped with ADODB under Windows 2008 Server R2. If I run this query:

SELECT SUM(PaymnetAmounts) AS Res FROM Customers WHERE CustID = 1

I get this error:

-2147467259
Unspecified error

If I run any other more simple select query, code runs ok.

I'm using MYSQL 32bit.

Anyone able to help?
