Driver Configuration Keyword

Dummy_Zero_Date_Value

Remarks

Sets up the value of the dummy zero date. This should be set to the lowest possible date value that the database supports. In most databases, the default 0001-01-01 can be used. Some databases, however, support a different lowest possible date value.

This default value is copied to the database level when logging in to the database. The actual value in use for an active connection is that on the database level. This attribute merely reflects a default.

Sample Code

The sample code below shows the current setting for a given driver.

Function DriverIndex String sDriver Returns Integer
    String sCurrentDriver
    Integer iNumberOfDrivers iDriver iCount

    Move 0 to iDriver
    Get_Attribute DF_NUMBER_DRIVERS to iNumberOfDrivers

    For iCount From 1 To iNumberOfDrivers
        Get_Attribute DF_DRIVER_NAME of iCount To sCurrentDriver
        If (Uppercase(sCurrentDriver) = Uppercase(sDriver)) Begin
            Move iCount to iDriver
        End
    Loop

    Function_Return iDriver
End_Function // DriverIndex

Procedure ShowDriverAttribute
    String sAttribValue
    Integer iDriver

    Get DriverIndex "MSSQLDRV" to iDriver
    Get_Attribute DF_DRIVER_DUMMY_ZERO_DATE_VALUE of iDriver to sAttribValue
    Showln "Dummy zero date: " sAttribValue
