DF_DRIVER_DEFAULT_RECORD_IDENTITY_HIDING

Indicates if "recnum" columns are hidden.

Level

Driver

Supported by

The DataFlex SQL Drivers (SQL Server, DB2, and ODBC), revision 5 and higher.

Type

Boolean, temporary.

Access

Read/Write.

Values

  • True
  • False

Syntax

Use cli.pkg
Get_Attribute DF_DRIVER_DEFAULT_RECORD_IDENTITY_HIDING of {driverNumber} to {BooleanVariable}
Set_Attribute DF_DRIVER_DEFAULT_RECORD_IDENTITY_HIDING of {driverNumber} to {True|False}

Driver Configuration Keyword

Default_Record_Identity_Hiding

Remarks

Up to version 3 of the CLI-based drivers, record identities were not hidden. A column called "DFRECNUM" was added to the end of a table and this column was visible. Setting this attribute to true will hide these columns from the table definition.

Example Code

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
    Boolean bAttribValue
    Integer iDriver
    Get DriverIndex "MSSQLDRV" to iDriver
    Get_Attribute DF_DRIVER_DEFAULT_RECORD_IDENTITY_HIDING of iDriver to bAttribValue
    Showln "Hide recnum: " (If(bAttribValue, "YES", "NO"))
End_Procedure
