獲取從列唯一編號使用SQL

Question

你好，

我想通過使用從列ProecssInstanceName一個SQL查詢來獲取的唯一編號。快照如下所示。

現在我使用此查詢來獲取以下結果。查詢是

select c.StreamName AS Category,ProcessInstanceAppianID as jobId,a.ProcessInstanceName,a.ProcessInstanceTargetDate AS TargetDate,a.ProcessInstanceDescription as TaskDescription,b.Name as department 
from InternalUseOnly..ProcessInstance a 
join InternalUseOnly..Departments b on b.KeyDepartment=a.KeyDepartmentEntered AND b.updoperation <2 
join InternalUseOnly..ProcessStream c on c.KeyProcessStream=a.KeyProcessStream and c.updoperation <2 
where ProcessInstanceCompleted is null 
and a.KeyProcessStream in 
(330) and a.updoperation <2 

在此先感謝。

你想要這個嗎？

select c.StreamName AS Category,ProcessInstanceAppianID as jobId,a.ProcessInstanceName,a.ProcessInstanceTargetDate AS TargetDate,a.ProcessInstanceDescription as TaskDescription,b.Name as department, 
SUBSTRING(ProcessInstanceName,NULLIF(PATINDEX('%[0-9][0-9][0-9][0-9][0-9][0-9][0-9]%',ProcessInstanceName),0),7) as code 
from InternalUseOnly..ProcessInstance a 
join InternalUseOnly..Departments b on b.KeyDepartment=a.KeyDepartmentEntered AND b.updoperation <2 
join InternalUseOnly..ProcessStream c on c.KeyProcessStream=a.KeyProcessStream and c.updoperation <2 
where ProcessInstanceCompleted is null 
and a.KeyProcessStream in 
(330) and a.updoperation <2 

編輯： 我做了這個：

SUBSTRING(ProcessInstanceName, PatIndex('%[0-9]%', ProcessInstanceName), (LEN(ProcessInstanceName) - (PatIndex('%[0-9]%', ProcessInstanceName) - 1) - (PatIndex('%[0-9]%', REVERSE(ProcessInstanceName)) - 1)) + 1) 

但我認爲這是瘋狂的，更好的是C＃或者你用什麼來解析號碼。

Answer 2

我建議使用string functions。 REPLACE「Webwatcher再過濾網址的」空白並使用LEFT與PATINDEX合力得到ID和演員陣容的數量。
