MySQL中将数据库表名修改成大写的存储过程

创建存储过程的代码：

DROP PROCEDURE IF EXISTS uppercaseTablenames;
DELIMITER $
CREATE PROCEDURE uppercaseTablenames(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);
SET @isNotSame = @newname <> BINARY oldname;
IF NOT done && @isNotSame THEN
SET @SQL = CONCAT('rename table `',oldname,'` to `', LOWER(@newname), '_tmp` ');
PREPARE tmpstmt FROM @SQL;
EXECUTE tmpstmt;
SET @SQL = CONCAT('rename table `',LOWER(@newname),'_tmp` to `',@newname, '`');
PREPARE tmpstmt FROM @SQL;
EXECUTE tmpstmt;
