VARIANT_TRUE |
An update or delete can affect multiple rows, and the provider can detect that multiple rows have been updated or deleted. This happens when a provider cannot uniquely identify a row. For example, the provider might use the values of all the columns in the row to identify the row; if these columns do not include a unique key, an update or delete might affect more than one row. |
VARIANT_FALSE |
An update or delete always affects a single row, or the provider cannot detect whether it affects multiple rows. |
