这篇文章主要为大家详细介绍了MYSQL将表名称修改成大写的存储过程，感兴趣的小伙伴们可以参考一下
本文为大家分享了MYSQL将表名称修改成大写的存储过程，具体内容如下
1. 条件：
1.1 Mysql设置对大小写敏感
2. 执行下述存储过程：
#call uppercase('库名')
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);
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;
DEALLOCATE PREPARE tmpstmt;
END IF;
UNTIL done END REPEAT;
CLOSE cur;
END
3. 执行一下语句
call uppercase('库名');
