Stored Procedures that creates a table

Question

Can I create tables using Stored Procedures?

I am using MySQL. I had searched the web for instructions on how to create a table using stored procedure, but I didn't find any results, I just found that you can create temporary tables. Is there any problem if I create tables using stored procedures?

Actually I want to check whether a table exists or not, then I have to create it.

Answer 1

You can create tables using procedures in mysql.

CREATE PROCEDURE SP_CREATE_TABLE_TEST ()
   BEGIN
      CREATE TABLE TEST 
      (
        TestID int(11) default NULL,
        TestName varchar(100) default NULL
      ) 
      ENGINE=InnoDB DEFAULT CHARSET=utf8;
   END;

EDIT: Thanks Peter! So the solution to this particular problem:

DELIMITER //
CREATE PROCEDURE createTable(IN tableName VARCHAR(40))
BEGIN
SET @table := tableName;
SET @sql_text:=CONCAT('CREATE TABLE ',@table,'(id INT NOT NULL AUTO_INCREMENT, FILENAME VARCHAR(40) NOT NULL, DATA BLOB NOT NULL, PRIMARY KEY (ID))');

PREPARE stmt from @sql_text;
EXECUTE stmt;
END //
DELIMITER ;

In addition to the manual I also found a very helpful tut by Roland Bouman at:
