Question

我正在SQL Server 2012表上编写触发器。触发器本身工作正常，除了当我从触发器更新表后添加语句发送电子邮件时，ELSE语句突出显示错误

ELSE附近的语法不正确

我可能有语法错误，但我无法指出。

我试图添加“;”在第10行和第11行的末尾，但它没有做到这一点。注释第11行将使整个触发器正常工作

在IF之后有两个声明/动作的最佳方法是什么？

1 CREATE TRIGGER dbo.MembersNameToCategories ON dbo.Members
2 AFTER UPDATE
3 AS 
4 
5 BEGIN
6   DECLARE @OldName NVARCHAR(150) = (SELECT name FROM Deleted)
7   DECLARE @NewName NVARCHAR(150) = (SELECT name FROM Inserted)
8   DECLARE @BodyTXT nvarchar(MAX) = 'Customer: ' + @oldName + ' has been modified with new name : ' +@NewName + '.'
9   IF EXISTS (SELECT NULL  FROM Categories AS c WHERE c.Name = @OldName)
10      UPDATE Categories SET Name = @NewName WHERE Name = @OldName AND CategoryType = 7
11      EXEC msdb.dbo.sp_send_dbmail @profile_name = 'MyProfile',@recipients = 'tous@mycompany.ca',@body_format = 'HTML',@body = @BodyTXT,@subject = 'A customer name has been modified'
12  ELSE
13      INSERT INTO Categories (ID,Modified,ModifiedByID,CategoryType,Name,Colour,RANK,MemberType,Private,DefaultCategory,Description,SendNotification)
14          VALUES (    
15          NEWID(),
16          GETDATE(),
17          dbo.fnmyid(),
18          7,
19          @NewName,
20          -8000,
21          9999,
22          0,
23          0,
24          0,
25          N'',
26          0
27          )
28 END;
29 GO

试试这个：

IF EXISTS (SELECT NULL  FROM Categories AS c WHERE c.Name = @OldName)
BEGIN
      UPDATE Categories SET Name = @NewName WHERE Name = @OldName AND CategoryType = 7
      EXEC msdb.dbo.sp_send_dbmail @profile_name = 'MyProfile',@recipients = 
'tous@mycompany.ca',@body_format = 'HTML',@body = @BodyTXT,@subject = 'A customer name has been modified'
END
ELSE

如何在触发器中使用两个语句
