MYSQL将表名称修改成大写的存储过程

#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;
