Solution 1

You could use

DELETE FROM mytable WHERE ID_no=16751

then insert a new record, or better just use an UPDATE command instead, and specify the new values:

UPDATE mytable SET mycol='new value' WHERE ID_no=16751

Solution 2

Trying to update marks column value as null

update Table1 set marks=null where ID_No=16751

And then update the marks column value with your new value

update Table1 set marks='NewValue' WHERE ID_No=16751
