ORA-01502: index 'INDEX_NAME' or partition of such index is in unusable state

ORA-01502: index 'INDEX_NAME' or partition of such index is in unusable state

原因:

  这个错误一般是因为索引状态为UNUSABLE引起的。你可以通过下面SQL,查看索引的状态

解决办法:

SELECT OWNER, INDEX_NAME,STATUS  FROM DBA_INDEXES WHERE INDEX_NAME='INDEX_NAME';
SELECT OWNER, INDEX_NAME,STATUS  FROM ALL_INDEXES WHERE INDEX_NAME='INDEX_NAME';
SELECT  INDEX_NAME,STATUS  FROM USER_INDEXES WHERE INDEX_NAME='INDEX_NAME';

重建索引即可

ALTER INDEX INDEX_NAME REBUILD
