   ### Description
   
   This method can realize the RENAME of the temporary table  under the atomic 
operation.
   
   
   
   ### Use case
   
   
   for  :  a _1 to a_2
   
   ```
   a_1 rename a_temp
   a_2 rename a_1
   a_temp rename a_1
   ```
   it`s  not atomical
   
   
   
   but :
   
   ```
   exchange tables name_1 and name_2;
   ```
   it will be atomical
