rebuild 索引遭遇ORA-02243

rebuild index 是，rebuild要紧跟索引名后面，在其他选项前面，否则会报错：

SQL> alter index IND_ABC rebuild;

Index altered.

SQL> alter index IND_ABC online rebuild;
alter index IND_ABC online rebuild
                    *
ERROR at line 1:
ORA-02243: invalid ALTER INDEX or ALTER MATERIALIZED VIEW option

online和rebuild调换位置：

SQL>
SQL> alter index IND_ABC rebuild online;

Index altered.
