    Hi Julien,

    Many ReportBuilder DADE plugins use this SQL command to obtain your
    table field names. This command should return 0 records and execute
    fairly quickly and is the only way in many cases to get a list of your
    field names so they can be accessed in DADE.

    Depending on which plugin your are using, check the
    TdaXXXDataset.SetDataName routine for where this is done. Some data
    access components offer more optimized methods such as Interbase Express.

    Best Regards,
