SELECT或變量的SQL替換（）函數

Question

insert into PendingEmails (Subject,Body,ToEmail,PendingEmailStatusID) 
select REPLACE(select subject from dbo.EmailTemplates where ID = 7), '[CallID]'), (select Body from dbo.EmailTemplates where ID = 7) ,contact.Email ,5 
FROM inserted AS i inner join Calls on i.CallID = Calls.CallId inner join Contact on calls.ContactID = Contact.ContactID 
where contact.Email is not null and contact.Email <> '' 

我想用值替換主題中的[CallID]。該語法不起作用。 我也試過使用一個變量，也不會工作。

這樣做的最好方法是什麼？

Answer 1

insert into PendingEmails (Subject) 
select REPLACE(subject, '[CallID]', @callid) 
from dbo.EmailTemplates 
where ID = 7 

我看不到你在哪裏加入到呼叫表得到calls.callid，你已經存儲它變成一個變量？

可以跳過變量，如果你有這將產生它的子查詢（括號標量子查詢）

insert into PendingEmails (Subject) 
select REPLACE(subject, '[CallID]', (select callid from calls where id=9)) 
from dbo.EmailTemplates 
where ID = 7 

或加入它

insert into PendingEmails (Subject) 
select REPLACE(e.subject, '[CallID]', c.callid) 
from dbo.EmailTemplates e 
join calls c on c.id=9 
where e.ID = 7 

Answer 2

你有一些有心計的括號：

insert into PendingEmails (Subject) 
select REPLACE((select subject from dbo.EmailTemplates where ID = 7), '[CallID]' , calls.callid) 

Answer 3

INSERT INTO PendingEmails (Subject) 
SELECT REPLACE(subject, '[CallID]' , calls.callid) 
    FROM dbo.EmailTemplates 
WHERE ID = 7
