(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
