如何在另一个表上的CREATE TABLE或ALTER TABLE上设置AUTO_INCREMENT？
我发现了这个问题,但没有解决我的问题：
How to Reset an MySQL AutoIncrement using a MAX value from another table?
我也试过这个：
CREATE TABLE IF NOT EXISTS `table_name` (
`id` mediumint(6) unsigned NOT NULL AUTO_INCREMENT,`columnOne` tinyint(1) NOT NULL,`columnTwo` int(12) NOT NULL,PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=(SELECT `AUTO_INCREMENT` FROM `INFORMATION_SCHEMA`.`TABLES` WHERE `TABLE_SCHEMA` = 'database_name' AND `TABLE_NAME` = 'another_table_name');
这个：
ALTER TABLE `table_name` AUTO_INCREMENT=(SELECT `AUTO_INCREMENT` FROM `INFORMATION_SCHEMA`.`TABLES` WHERE `TABLE_SCHEMA` = 'database_name' AND `TABLE_NAME` = 'another_table_name');
这个：
CREATE TABLE IF NOT EXISTS `table_name` (
`id` mediumint(6) unsigned NOT NULL AUTO_INCREMENT,PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=(SELECT (MAX(`id`)+1) FROM `another_table_name`);
还有这个：
ALTER TABLE `table_name` AUTO_INCREMENT=(SELECT (MAX(`id`)+1) FROM `another_table_name`);
最佳答案
此代码将为您创建过程：
CREATE PROCEDURE `tbl_wth_ai`(IN `ai_to_start` INT)
BEGIN
SET @s=CONCAT('CREATE TABLE IF NOT EXISTS `table_name` (
`id` mediumint(6) unsigned NOT NULL AUTO_INCREMENT,PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT = ',`ai_to_start`);
PREPARE stmt FROM @s;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
END;
然后你可以打电话给CALL tbl_wth_ai(2);在括号内传递参数.
例如：
CALL tbl_wth_ai((SELECT id FROM `ttest` WHERE c1='b'));
