   > If so, we also need to be able to specify the name of corresponding formal 
partition for the temporary partition in the statement. This makes the 
statement more complicated.
   
   In the statement the replaced partition is already specified.
   
   ```
   ALTER TABLE tbl REPLACE PARTITION (p1, p2) WITH TEMPORARY PARTITION (tp1, 
tp2, tp3);
   ```
   
   We must keep the range of partition p1 p2 is the same with the range of 
partition tp1, tp2 and tp3.
