Oracle 视图 ALL_IND_PARTITIONS 官方解释,作用,如何使用详细说明
本站中文解释
ALL_IND_PARTITIONS视图用于描述当前用户或指定用户拥有的索引类型分区的信息,包括索引名称、索引类型、分区名称、分区子分区名称和分区子分区的值的范围。
使用ALL_IND_PARTITIONS视图的方法类似SELECT * FROM DBA_IND_PARTITIONS,不过此处使用的是ALL_IND_PARTITIONS视图,此处查询的是当前用户或者指定用户的索引类型分区信息,而不是所有用户的索引类型分区信息。
例如:一个根据索引值进行查询的例子:
SELECT * FROM ALL_IND_PARTITIONS WHERE index_name=’TEST_INDEX’ AND partition_name=’TEST_PARTITION’ AND lower_bound=’51’ AND upper bound=’60’;
官方英文解释
