MYSQL表名批量改为大写

要在大小写敏感的mysql数据库环境(windows大小写不敏感，只有linux可以)下执行，否则会有问题.

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('your db name');
#
