I am trying to find the NULL records. when I type: where V0 = 'NULL' it gives the following error:

Msg 8114, Level 16, State 5, Line 2
Error converting data type varchar to bigint.

when I type the condition as : where V0 = NULL
it brings no record while I know there are records where V0=NULL

SELECT [O]
,[D]
,[M]
,[C]
,[V0]
,[T0]
,[TM0]
FROM [bts].[dev].[xListOfChildrentAlList]
where V0 = 'NULL'

Thank you

NULL is not stored as a value so operators =,>,< etc wont work with it under default conditions. (ANSI NULL setting)
