Am I on the right track?
Started designing a View (MS Access can link to a view). The Oracle data is Read-Only.
The Oracle data residing in SQL Server will be where the View is run from.
Tried this and it looks promising:
SELECT TOP 1000 (CAST( [Audit_ID] as varchar(5) ) ) as Audit_ID
My reading indicates that CAST can only be used on fields with no Nulls or no Non-Numeric values.
A PK is a good candidate for CAST
