    Diffrence between QVX_NULL_FLAG_SUPPRESS_DATA and QVX_NULL_FLAG_WITH_UNDEFINED_DATA

    Mike Rewnick

      Hello

       

      We are curretly in process of adding support for QVX files to our ETL tools Advanced ETL Processor and Visual Importer ETL.

       

      I am confused and can't see any diffrence between QVX_NULL_FLAG_SUPPRESS_DATA and QVX_NULL_FLAG_WITH_UNDEFINED_DATA

       

      QVX_NULL_FLAG_WITH_UNDEFINED_DATA

      A single byte (with binary value 1 or 0) in front of the

      field value signifies NULL or not. A 1 means it is NULL

      and the field value is not used.

       

      QVX_NULL_FLAG_SUPPRESS_DATA

      A single byte (with binary value 1 or 0) signifies NULL

      or not.

      A 1 means it is NULL and no field value is

      passed. A 0 byte means a normal value follows.
