Clear all tables with one DELETE
Here is your solution

SELECT CONCAT('DELETE ',delete_list,' FROM ',table_list)
INTO @mass_delete_table_command
FROM
(
    SELECT GROUP_CONCAT(table_name,'.*') delete_list,
    GROUP_CONCAT(table_schema,'.',table_name) table_list
    FROM
    (
        SELECT table_schema,table_name
        FROM information_schema.tables
        WHERE table_schema=database() AND
        table_name IN
        ('jos_bet_details','jos_bet_1x2','jos_bet_1x2_best','jos_bet_1x2_prev',
         'jos_bet_1x3','jos_bet_1x3_best','jos_bet_1x3_prev','jos_bet_hcp',
         'jos_bet_hcp_best','jos_bet_hcp_prev','jos_bet_ou','jos_bet_ou_best',
         'jos_bet_ou_prev','jos_bet_debug','jos_bet_deleted')
    ) ListOfTables
) DeleteParameters;
PREPARE s1 FROM @mass_delete_table_command;
EXECUTE s1;
DEALLOCATE PREPARE s1;


Here is the principle behind this: You want to use information_schema.tables to build the DELETE query dynamically for you.

First collect the names of the tables in a variable called 'mass_delete_table_command' as a delete list and a table list. Then, execute it as a prepared statement.

Here is sample code from creating 4 tables, adding records them, and zapping the records:

use test
DROP TABLE IF EXISTS t1;
DROP TABLE IF EXISTS t2;
DROP TABLE IF EXISTS t3;
DROP TABLE IF EXISTS t4;
CREATE TABLE t1 (n int NOT NULL);
CREATE TABLE t2 like t1;
CREATE TABLE t2 like t1;
CREATE TABLE t3 like t1;
CREATE TABLE t4 like t1;
INSERT INTO t1 VALUES (1),(2),(3),(4),(5),(6),(7);
INSERT INTO t2 SELECT * FROM t1;
INSERT INTO t3 SELECT * FROM t1;
INSERT INTO t4 SELECT * FROM t1;
SELECT A.*,B.*,C.*,D.* FROM
(SELECT COUNT(1) t1count FROM t1) A,
(SELECT COUNT(1) t2count FROM t2) B,
(SELECT COUNT(1) t3count FROM t3) C,
(SELECT COUNT(1) t4count FROM t4) D;
SELECT CONCAT('DELETE ',delete_list,' FROM ',table_list)
INTO @mass_delete_table_command
FROM
(
    SELECT GROUP_CONCAT(table_name,'.*') delete_list,
    GROUP_CONCAT(table_schema,'.',table_name) table_list
    FROM
    (
        SELECT table_schema,table_name
        FROM information_schema.tables
        WHERE table_schema=database() AND
        table_name IN ('t1','t2','t3','t4')
    ) ListOfTables
) DeleteParameters;
SELECT @mass_delete_table_command;
PREPARE s1 FROM @mass_delete_table_command;
EXECUTE s1;
DEALLOCATE PREPARE s1;
SELECT A.*,B.*,C.*,D.* FROM
(SELECT COUNT(1) t1count FROM t1) A,
(SELECT COUNT(1) t2count FROM t2) B,
(SELECT COUNT(1) t3count FROM t3) C,
(SELECT COUNT(1) t4count FROM t4) D;


I ran this in MySQL 5.5.12 on my PC. Here is the output:

mysql&gt; use test
DROP TABLE IF EXISTS t1;
DROP TABLE IF EXISTS t2;
DROP TABLE IF EXISTS t3;

INSERT INTO t4 SELECT * FROM t1;

This will definitely work for you as long as


you are standing in the correct database at the time
you suppply the list of tables you want dropped to the subqueries


Give it a Try !!!
