            end
    end
SET NOCOUNT OFF

问题是转型

OUTPUT 'OK/'+CAST(insterted.Active as nvarchar) rspn

将值放在@R中，但不知道如何操作

我搜索了很多但没有找到解决方案： - （

可以给我一些指示

谢谢！

声明表变量和OUTPUT INTO temp_Table

像这样......

SET NOCOUNT ON
DECLARE @ID int;
DECLARE @ID_TABLE TABLE (ID VARCHAR(100))

IF EXISTS
(
    select d.name
    from users s
    join users g on CHARINDEX(s.UserID,g.ParentOf)>0
    join booking b on charindex(s.ClassRoom,b.class)>0
    join interview w on b.id=w.bookingID
    join users d on d.userid=b.teacherID
    where (g.UserID=@U and g.Password=@P and b.active='1' and g.Role='parent' 
            and b.teacherID=@T and w.Time=@O and w.studentID=@S and b.[Day]=@D )  
)
    begin
        update w 
         set w.Active= ~ w.Active 
        output 'OK/'+cast(inserted.Active as nvarchar) INTO @ID_TABLE(ID)
        from users s
        join users g on CHARINDEX(s.UserID,g.ParentOf)>0
        join booking b on charindex(s.ClassRoom,b.class)>0
        join interview w on b.id=w.bookingID
        join users d on d.userid=b.teacherID
        where (g.UserID=@U and g.Password=@P and b.active='1' and g.Role='parent' 
                  and w.Time=@O and b.[Day]=@D );

-- select the ID into a variable or return a table execute one of the following
   SELECT @ID = ID FROM @ID_TABLE  --<-- If it will only return a single value
   SELECT * FROM @ID_TABLE         --<-- If it can update multiple rows at a time
    end
