Question

select top 1(SUBSTRING(patientid,9,4)) as MaxpatientID from Patient_Data
where PatientID like 'AT112013%' order by PatientID desc;

将结果显示为

MaxPatientID
0014

现在有可能增加这个数字，例如ex：

0015
0016
0017

我尝试了这个查询，但它不值得使用

update Patient_Data  set (top 1(SUBSTRING(patientid,9,4)) as MaxpatientID)=(MaxpatientID + 1)
where PatientID like 'AT112013%' order by PatientID desc;

任何帮助表示感谢。

Answer 1

update patientid = SUBSTRING(patientid,0,9)) + convert(varchar(32), convert(int, SUBSTRING(patientid,9,4)) + 1) where patientid like 'AT112013%'

Answer 2

我刚试过mysql。希望这符合您的要求：

UPDATE test SET patientId = (SELECT patientId
FROM
(
    SELECT CONCAT(SUBSTRING(patientId, 1, 6), CAST(SUBSTRING(patientId, 4, 2) AS UNSIGNED) +1) 
    FROM test
    WHERE `patientId` LIKE 'AT112013%') AS temp
)

使用更新查询增加特定值
