I have never been able to use a user-defined VBA function in an access query
when using ADO/DAO from excel: I do not think its possible except by getting
the recordset and then processing it using the function (which would then
have to be in the Excel VBA space).

While I trying to run ADO following statement
rs.Open "abcd", cn, adOpenStatic, adLockOptimistic,
adCmdTable
I got error "run time error'-2147217900(80040e14)':
undefined function "abc" in expression

note: abcd is a query defined in access, abc is a function
defined in access to get specific date.
here is query abcd:
SELECT DISTINCT * FROM Order_info INNER JOIN Revenue ON
Order_info.O_ID = Revenue.O_ID
WHERE ( ((Order_info.CONNECT_DT)=abc() );
