Question

I have tabel with two columns

Now if I insert or update column1 with value 0, column2 should not accept any value and should be null

Is their any way to add this constraint

Answer 1

While Creating table, you can add the CHECK constraint in following way:

CREATE TABLE tableDemo (
   column1  int, 
   column2  varchar(50),
   CONSTRAINT CK_column1_column2 CHECK ((column1 = 0 AND column2 IS NULL) OR column1 != 0)
)
