sql - 查找表分区详细信息

Question

可能重复：
如何获取有关 Oracle 中表的所有信息？

我需要将分区添加到现有表中，我们没有生产数据库访问权限，我们需要发送 sql 查询以查找有关现有分区的详细信息，我试过了

desc <table-name>;

但它只提供有关表结构的信息，我们需要表结构以及分区详细信息。

数据库是oracle 10g

谢谢

get_ddl包的功能dbms_metadata会给你这样的信息：

SQL> create table Tb_Test(
  2    id number primary key
  3  )
  4  partition by range(id)(
  5    partition part1 values less than (100),
  6    partition part2 values less than (300),
  7    partition part3 values less than (maxvalue)
  8  )
  9  ;

Table created 

SQL> select dbms_metadata.get_ddl('TABLE', 'TB_TEST')
  2    from dual
  3  ;

DBMS_METADATA.GET_DDL('TABLE',
