#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
