| Cause: | An attempt was made to update a table column "USER"."TABLE"."COLUMN" with a NULL value. For example, if you enter:
connect scott/tiger update table a (a1 number not null); insert into a values (null);
Oracle returns:
ORA-01407 cannot update ("SCOTT"."A"."A1") to NULL
which means you cannot update the column "SCOTT"."A"."A1" to NULL. |
