    Hi Soobramoney ,

     

    For this type of problem, you can make sure that the columns are defined with the correct data types when you create a new table, and allow null values if necessary.

    The following demonstrates the successful insertion of a NULL value in a table:

    CREATE TABLE [NullCheck1]
(
    col1 int not null,
    col2 VARCHAR(30) NULL,
    col3 VARCHAR(30) not NULL,
    col4 int NULL
)
GO


INSERT INTO [NullCheck1] VALUES (3,NULL,'NA',NULL)


select * from  [dbo].[NullCheck1]

     

    Best Regards,
    Adamk Kong
