(转)mysql数据库表名批量修改大小写

由于不用服务器对mysql的表名的大小写敏感要求不一致，经常在出现线上的数据库down到了本地不能运行的情况，贴出一段代码用来批量修改数据库表名大小写。

DELIMITER //   

DROP PROCEDURE IF EXISTS uppercase //   

CREATE PROCEDURE uppercase(IN dbname VARCHAR(200))   

BEGIN  

DECLARE done INT DEFAULT 0;   

DECLARE oldname VARCHAR(200);   

DECLARE cur CURSOR FOR SELECT table_name FROM information_schema.TABLES WHERE table_schema = dbname;   

DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;   

OPEN cur;   

REPEAT   

FETCH cur INTO oldname;   

SET @newname = UPPER(oldname);   

#IF newname equals to oldname, do nothing;
#select 'a' <> 'A'; -> 0
#select 'a' <> BINARY 'A'; -> 1
SET @isNotSame = @newname <> BINARY oldname;   

IF NOT done && @isNotSame THEN  

SET @SQL = CONCAT('rename table ',oldname,' to ',@newname);   

PREPARE tmpstmt FROM @SQL;   

EXECUTE tmpstmt;   

DEALLOCATE PREPARE tmpstmt;   

END IF;   

UNTIL done END REPEAT;   

CLOSE cur;   

END //   

DELIMITER ;
#调用存储过程
#call uppercase('TEST');
#TEST为你想要修改的数据库的名称
