最近项目中用到了使用存储过程批量建表的功能,记录下来:
USE db_test_3; drop procedure if EXISTS `createTablesWithIndex`; create procedure createTablesWithIndex() BEGIN DECLARE `@i` int(11); DECLARE `@createSql` VARCHAR(2560); DECLARE `@createIndexSql1` VARCHAR(2560); DECLARE `@createIndexSql2` VARCHAR(2560); DECLARE `@createIndexSql3` VARCHAR(2560); set `@i`=0; WHILE `@i`< 64 DO -- `M_ID` bigint AUTO_INCREMENT PRIMARY KEY NOT NULL, -- 创建表 SET @createSql = CONCAT(‘CREATE TABLE IF NOT EXISTS test_‘,`@i`,‘( `t_ID` bigint AUTO_INCREMENT PRIMARY KEY NOT NULL, `t_CODE` varchar(30) DEFAULT NULL, )‘ ); prepare stmt from @createSql; execute stmt; -- 创建索引 set @createIndexSql1 = CONCAT(‘create index `t_code` on test_‘,`@i`,‘(`t_code`);‘); prepare stmt from @createIndexSql1; execute stmt; SET `@i`= `@i`+1; END WHILE; END
