mysql create table dynamically

Question

I am creating a database on mysql. First creating the principal tables which on average has 30 columns per table. And the standard of the log table is the pk of the referenc

Answer 1

To make a string represent a table (or database) name you will need to concat your query string with the variable and prepare/execute a statement right in the stored procedure. Here's a basic example.

-- DROP PROCEDURE IF EXISTS createLogTable;
DELIMITER //
CREATE PROCEDURE createLogTable(tblName VARCHAR(255))
BEGIN
    SET @tableName = tblName;
    SET @q = CONCAT('
        CREATE TABLE IF NOT EXISTS `' , @tableName, '` (
            `id` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
            `something` VARCHAR(10) NOT NULL,
            `somedate` DATETIME NOT NULL,
            PRIMARY KEY (`id`)
        ) ENGINE=MyISAM DEFAULT CHARSET=utf8
    ');
    PREPARE stmt FROM @q;
    EXECUTE stmt;
    DEALLOCATE PREPARE stmt;
    -- and you're done. Table is created.
    -- process it here if you like (INSERT etc)
END //

Then… CALL createLogTable('exampleTable');

So the basic idea is

1. concat the procedure parameter(s) with your query as necessary
2. prepare/execute a statement from this query string
