MDAC 2.5 SDK - ODBC Desktop Database Drivers
The syntax:
expression1 BETWEEN expression2 AND expression3
returns true only if expression1 is greater than or equal to expression2 and expression1 is less than or equal to expression3.
The semantics of this syntax are different for the Desktop Database Drivers and the Microsoft Jet engine. In Microsoft Jet SQL, expression2 can be greater than expression3 so that the statement will return TRUE only if expression1 is greater than or equal to expression3, and expression1 is less than or equal to expression2.
