RE: Visual Basic SQl statement -- MIDRANGE-L

Yes, but it's not a date, it's an 8 position numeric field that the
programmers use as a date. Big difference.

If that date was a PC SQL date, you would want #20021211# ,as best I
remember. Don't know what happens when you go to the AS/400 thru ODBC or OLE


The # at the start and end are field delimiters like quotes for text, that
say this is a date
