ORA-28659: 必须首先在对象级指定 COMPRESS

打算把老数据的索引给压缩下，结果做不了，报ORA-28659

SQL> DROP TABLE test_partition;

Table dropped

SQL>
SQL> CREATE TABLE test_partition
  2  ( ID NUMBER,NAME VARCHAR2(200)
  3  )
  4  PARTITION BY RANGE (ID)
  5  (PARTITION test01 VALUES LESS THAN (100),
  6  PARTITION test02 VALUES LESS THAN (200),
  7  PARTITION test03 VALUES LESS THAN (300),
  8  PARTITION test04 VALUES LESS THAN (MAXVALUE))
  9  /

Table created

SQL> CREATE INDEX idx_test_PARTITION on test_partition (ID) local;

Index created

SQL> alter index idx_test_PARTITION rebuild partition test01 compress;

alter index idx_test_PARTITION rebuild partition test01 compress

ORA-28659: COMPRESS must be specified at object level first

解决方法也很奇怪，先建立compress的local索引，在把不需要compress的分区给nocompress

SQL> drop index idx_test_PARTITION;

Index dropped

SQL> CREATE INDEX idx_test_PARTITION on test_partition (ID) LOCAL COMPRESS;

Index created

SQL>
SQL> alter index idx_test_PARTITION rebuild partition test04 nocompress;

Index altered
SQL> alter index idx_test_PARTITION rebuild partition test02 nocompress;

Index altered
SQL> alter index idx_test_PARTITION rebuild partition test03 nocompress;

Index altered

但是，这个时候，如果想把个别分区给compress是可以的：

SQL> alter index idx_test_PARTITION rebuild partition test02 compress;

Index altered

估计一个分区索引的个别分区能否compress是和对象级别的能否compress相关的

表的分区能独立的compress
