The null value check is performed every time the table is touched, not on a per batch level ! Insert into xyz ( col1, col6 ) values (1,'C')
update xyz set col2='abc' where col1 = 1 ;
go
The batch ends with the 'go' in SSMS
The first statement will fail if col2 doesn't allow nulls and has no default value defined (other than null).
