ORA-02433: cannot disable primary key – primary key not defined for table
Cause: Attempted to disable a primary key tht is not defined for the table.
Action: None
ORA-02433 错误是由于数据库在尝试禁用一个表上的主键而引起的。
案例:
例如,当尝试使用以下语句禁用表EMPLOYEE上定义的主键时,ORA-02433可能会发生:
SQL> ALTER TABLE employee DISABLE PRIMARY KEY;
ORA-02433:不能禁用主键-没有为表定义主键
要解决ORA-02433的错误,首先需要在表上定义主键:
ALTER TABLE employee ADD CONSTRAINT my_primary_key_name PRIMARY KEY(column_name);
有了主键之后,就可以使用以下语句禁用它了:
ALTER TABLE employee DISABLE PRIMARY KEY;
