SQL> show user; USER is "TEST" SQL> create table rename_table ( id int); Table created. SQL> select table_name from user_tables; TABLE_NAME -------------------------------------------------------------------------------- RENAME_TABLE
SQL> show user; USER is "SYS" SQL> alter table test.RENAME_TABLE rename to test.RENAME_TABLE2; alter table test.RENAME_TABLE rename to test.RENAME_TABLE2 * ERROR at line 1: ORA-14047: ALTER TABLE|INDEX RENAME may not be combined with other operations
问题原因
Oracle是允许A用户修改B用户表名的,但是在新表名前是不能指定用户名的,使用如下方法修改表名成功。
SQL> alter table test.RENAME_TABLE rename to RENAME_TABLE2; Table altere SQL> select OWNER,TABLE_NAME from dba_tables where owner='TEST'; OWNER TABLE_NAME -------------------- -------------------- TEST RENAME_TABLE2

还有一个修改表名的命令rename to ,但是这个命令只能修改自己用户下表的表名
使用Sys用户修改test用户表的表名
SQL> show user; USER is "SYS" SQL> select OWNER,TABLE_NAME from dba_tables where owner='TEST'; OWNER TABLE_NAME -------------------- -------------------- TEST RENAME_TABLE2 SQL> rename test.RENAME_TABLE2 to RENAME_TABLE; rename test.RENAME_TABLE2 to RENAME_TABLE * ERROR at line 1: ORA-01765: specifying owner's name of the table is not allowed
切换为test用户,修改表名成功
SQL> show user; USER is "TEST" SQL> select OWNER,TABLE_NAME from dba_tables where owner='TEST'; OWNER TABLE_NAME -------------------- -------------------- TEST RENAME_TABLE2 SQL> rename RENAME_TABLE2 to RENAME_TABLE; Table renamed. SQL> select OWNER,TABLE_NAME from dba_tables where owner='TEST'; OWNER TABLE_NAME -------------------- -------------------- TEST RENAME_TABLE
