| Hello Friends, There is a column whose data type is DateTime which can contain NULL value. Now I want to compare this Column with Null. Select * from testtbl where exdt(Datetime) = NULL This query doesn't work. Suggest any other ways to achieve this.Thanks |

NULL values always compare with: WHERE Column IS NULLorWHERE Column IS NOT NULL
No, you're never too old to Yak'n'Roll if you're too young to die. |

I assume that exdt is the columnname and (Datetime) was a hint for us to know that it is a datetime column.
No, you're never too old to Yak'n'Roll if you're too young to die. |
