Hi All,

Can anyone please tell me what is the difference between these two queries:

     sel *
     From    test
     Where   Exit_Date Between '0001-01-01'
              And     '1900-01-01'

     sel *
     From    test
     Where   Exit_Date < '1900-01-01'
              And     Exit_Date > '0001-01-01'

First one returns me 35725730 records with Exit_Date as blank.

Second one returns 4 rows with values

     11/22/999
     11/22/999
     11/30/999

     04/23/1199

Also

     sel *
     From    Test
     Where
            Cast(Exit_Date As char) = ''

Returns no value.

Regards,

Shubhangi
