ORA-02429: cannot drop index used for enforcement of unique/primary key

SQL> drop index TMP1_INX;

drop index TMP1_INX

ORA-02429: cannot drop index used for enforcement of unique/primary key

解决方案：

SQL> ALTER TABLE employees

2 2 MODIFY PRIMARY KEY DISABLE;

SQL> drop index TMP1_INX;

Index dropped

SQL> create index tmp1_INX on tmp1 (DEALER_ID, CO_NO) local compress;

Index created

SQL> ALTER TABLE tmp1 MODIFY PRIMARY KEY ENABLE;

Table altered

注：由于有个字段在主键中，主键详见下面：

alter table TMP1

add constraint PK_TMP1 primary key (CO_NO, DEALER_ID);
