谢谢！
查看链接后，在评论中进行了一些调整后，我让它工作了。这是我用于将来参考的代码。

这是我使用的查询。
SET SESSION group_concat_max_len = 1000000;
SELECT
GROUP_CONCAT(DISTINCT
CAST(CONCAT('IFNULL((CASE WHEN `date` = ''', `date`, ''' THEN `measurement` END), NULL) AS ', `date`, '') AS CHAR)
)INTO @sql
FROM
`result` ORDER BY `date` DESC;
SET @sql = CONCAT('SELECT patient_id, universal_id AS `Parameter`, ', CAST(@sql as CHAR), '
FROM result
GROUP BY universal_id ORDER BY order_no');
PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
谢谢！
查看链接后，在评论中进行了一些调整后，我让它工作了。这是我用于将来参考的代码。
CREATE DEFINER=`root`@`localhost` PROCEDURE `delta_check`(IN PID VARCHAR(50), IN Section VARCHAR(50), IN SubSection VARCHAR(50))
BEGIN
SET @PID = PID;
SET @Section = Section;
SET @SubSection = SubSection;
SET SESSION group_concat_max_len = 1000000;
SELECT GROUP_CONCAT(DISTINCT CAST(CONCAT("MAX(CASE WHEN DATE_FORMAT(`date`, '%y-%m-%d %H:%i') = '", DATE_FORMAT(`date`, '%y-%m-%d %H:%i'), "' THEN `measurement` END) AS `", DATE_FORMAT(`date`, '%y-%M-%d %H:%i'), "`") AS CHAR)) FROM result WHERE `patient_id` = PID AND section = Section AND sub_section = SubSection INTO @sql;
SET @sql = CONCAT("SELECT result.universal_id AS Parameter, specimen.si_unit AS Unit, reference_range.si_range, result.test_code AS `TestCode`, ", @sql, ", result.`section` AS Section, result.`sub_section` AS SubSection
FROM result
LEFT JOIN specimen ON result.test_code = specimen.test_code
LEFT JOIN reference_range ON result.test_code = reference_range.test_code
WHERE result.`patient_id` = ? AND result.section = ? AND result.sub_section = ? GROUP BY result.test_code ORDER BY specimen.order_no ASC");
PREPARE stmt FROM @sql;
EXECUTE stmt USING @PID, @Section, @SubSection;
DEALLOCATE PREPARE stmt;
END
为大家的帮助干杯。
谢谢！
