Thanks but, this caused the whole row with a blank date1 to be null, but the non blank date1 rows were ok.

Any other suggestions?

>>We have a foxpro dbf file that contains a date field 'date1'. We need to import this dbf to SQL Server using the OLEDB driver. Sometimes the date1 field contains a blank date. We need to convert blank date data into a null. But when we run the following code, any blank date comes back as the date '12/30/1899' instead of a NULL.
