MySQL字符串 首字母转为大写

函数形式实现

CREATE DEFINER=`root`@`localhost` FUNCTION `CAP_FIRST`(input VARCHAR(255)) RETURNS varchar(255) CHARSET utf8
    DETERMINISTIC
BEGIN
	DECLARE len INT;
	DECLARE i INT;

	SET len   = CHAR_LENGTH(input);
	SET input = LOWER(input);
	SET i = 0;

	WHILE (i < len) DO
		IF (MID(input,i,1) = ' ' OR i = 0) THEN
			IF (i < len) THEN
				SET input = CONCAT(
					LEFT(input,i),
					UPPER(MID(input,i + 1,1)),
					RIGHT(input,len - i - 1)
				);
			END IF;
		END IF;
		SET i = i + 1;
	END WHILE;

	RETURN input;
END

看下效果

SELECT CAP_FIRST('this is totally like   @ TEST 1 right!' )

This Is Totally Like   @ Test 1 Right!
