sql - 使用 sysdate 更改表名

Question

我想通过附加 SYSDATE 来更改表名到它。比如我想换表EXAMPLE_TABLE至 EXAMPLE_TABLE_05_01_2015 ，但我想从 SYSDATE 获取日期.

我准备了以下内容，但它不起作用:

ALTER TABLE "MYDB"."EXAMPLE_TABLE" rename to (SELECT 'EXAMPLE_TABLE' || TO_CHAR(SYSDATE, '_dd_MM_yyyy') FROM DUAL);

我怎样才能让它工作？

这是错误:

SQL Error: ORA-14047: ALTER TABLE|INDEX RENAME may not be combined with other operations
14047. 00000 -  "ALTER TABLE|INDEX RENAME may not be combined with other operations"
*Cause:    ALTER TABLE or ALTER INDEX statement attempted to combine
           a RENAME operation with some other operation which is illegal
*Action:   Ensure that RENAME operation is the sole operation specified in
           ALTER TABLE or ALTER INDEX statement;

Answer 1

使用 execute immediate .

begin
   execute immediate 
   'alter table mydb.example_table rename to ' ||
   'example_table_' || to_char(sysdate, 'dd_mm_yyyy');
end;
/

也就是说，我有一种预感，您最好使用分区表。
