使用限制

    1. obclient> CREATE TABLE test(pk int,c2 int ,c3 int, PRIMARY KEY(pk)) PARTITION BY hash(pk) partitions 5;
    2. Query OK, 0 rows affected (0.20 sec)
    5. obclient> CREATE UNIQUE INDEX idx ON test(c2, pk) LOCAL;
    7. Query OK, 0 rows affected (0.02 sec)
    8. obclient> CREATE UNIQUE INDEX idx ON test(c2) GLOBAL;
