Drop, create and insert data into few intermediate tables

Question

Hi All,
I need to schedule a process to drop, create and insert data into few intermediate tables on a weekly basis. Here is what i need to do in the stored procedure, which can be scheduled weekly.
DROP TABLE TABLE_NAME1;
DROP TABLE TABLE_NAME2;
DROP TABLE TABLE_NAME3;
CREATE TABLE TABLE_NAME1
CREATE TABLE TABLE_NAME2
CREATE TABLE TABLE_NAME3
INSERT INTO TABLE_NAME1 SELECT ....;
INSERT INTO TABLE_NAME2 SELECT ....;
INSERT INTO TABLE_NAME3 SELECT ....;
Any suggestions, examples or code on how to accomplish this task would be very helpful. Any question pls let me know.
Thanks in advance.

I am using the intermediate tables in an extract process. The idea was that the table would be created prior to calling the extract procedure and once the data written to the intermediate table had been processed the table would be dropped. This would be repeated each time the extract process is run. From a DBA's point or view, would it be better to just leave the table on the database and truncate it after each run or is removing it entirely best?
