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 <> ''

我想用一个值替换主题中的'[CallID]'。该语法不起作用。我也试过使用变量，也不会工作。

最好的方法是什么？

Answer 1

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

我无法看到你在哪里加入调用表来获取calls.callid，你是否已将它存储到变量中？

如果你有一个可以产生它的子查询（括号标量子查询），你可以跳过该变量

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

或加入

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

你有一些括号恶作剧：

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

select或变量上的SQL Replace（）函数
