oracle中修改表名

<<<备忘>>>

answer1:

ALTER TABLE old_table_name RENAME TO new_table_name;(大写为系统命令)

answer2:

SQL> select tname from tab ;

TNAME

------------------------------

TEST

SQL> rename test to temp ;

Table renamed.

SQL> select tname from tab ;

TNAME

------------------------------

TEMP

rename只能修改自己schema下面的表。

answer3:

create new_table as select * from old_table;drop table old_table;
