This example queries the LabVIEW example database and then compares the first two elements. If the variants are ADO (Database) variants the comparison is always TRUE.

Therefore, this example shows how to convert the ADO variants to LabVIEW data types and LabVIEW variants. Once converted, the comparison occurs correctly.
