在sql server中插入触发器后

Question

我们可以在sql server中的索引视图上插入触发器后创建。

我在索引视图上的sql server中创建一个after插入触发器。

CREATE TRIGGER t_STUD_FUZZY_CERTIFICATIONS_mv 
ON STUD_FUZZY_CERTIFICATIONS_mv 
AFTER INSERT AS 

BEGIN 

DECLARE 

@count_rec int, 

@new_poor INT, 
@new_average INT, 
@new_excellent INT, 
@new_stud_num VARCHAR(10), 
@new_mem_set INT, 
@new_lname VARCHAR(25), 
@new_fname VARCHAR(25), 
@new_report_date date, 
@new_total_certs INT 


select @new_stud_num=stud_num, @new_mem_set=mem_set, @new_lname=lname, @new_fname=fname, @new_report_date=report_date, @new_total_certs=total_certs from inserted; 


select @count_rec = count (*) from fuzzy_param_trapezoid where MEM_SET = (select mem_set from inserted); 
--dbms_output.put_line(count_rec); 
if(@count_rec = 0) 

begin --if 

--update fuzzy attributes of stud_fuzzy_orders_mv 
SET @new_poor = dbo.FIT.update_certs_poor(@new_stud_num, @new_total_certs, @new_mem_set); 
SET @new_average = dbo.FIT.update_certs_average(@new_stud_num, @new_total_certs, @new_mem_set); 
SET @new_excellent = dbo.FIT.update_certs_excellent(@new_stud_num, @new_total_certs, @new_mem_set); 

INSERT INTO STUD_FUZZY_CERTIFICATIONS values(@new_stud_num, 
@new_mem_set, 
@new_lname, 
@new_fname, 
@new_report_date, 
@new_total_certs, dbo.FIT.update_certs_poor(@new_stud_num, @new_total_certs, @new_mem_set), 
dbo.FIT.update_certs_average(@new_stud_num, @new_total_certs, @new_mem_set), 
dbo.FIT.update_certs_excellent(@new_stud_num, @new_total_certs, @new_mem_set)); 

UPDATE STUD_FUZZY_CERTIFICATIONS_mv set POOR=@new_poor, AVERAGE=@new_average, EXCELLENT=@new_excellent where stud_num=@new_stud_num and mem_set=@new_mem_set; 

end;--end if 

END; 

GO 

我提示以下错误：

Msg 8197, Level 16, State 6, Procedure t_STUD_FUZZY_CERTIFICATIONS_mv, Line 1 
The object 'STUD_FUZZY_CERTIFICATIONS_mv' does not exist or is invalid for this operation. 

，我正确的数据库而已，对象STUD_FUZZY_CERTIFICATIONS_mv在数据库中现有的运行。

我认为你正在创建的触发器反对View而不是table。

您可能希望将数据插入到视图中不可见的列中。为此，请在视图上创建一个INSTEAD OF触发器来处理插入。

CREATE TRIGGER t_STUD_FUZZY_CERTIFICATIONS_mv ON STUD_FUZZY_CERTIFICATIONS_mv 
INSTEAD OF INSERT 
AS 
BEGIN 
    DECLARE @count_rec int,@new_poor INT,@new_average INT,@new_excellent INT,@new_stud_num VARCHAR(10),@new_mem_set INT, 
      @new_lname VARCHAR(25),@new_fname VARCHAR(25),@new_report_date date,@new_total_certs INT 

    SELECT @new_stud_num=stud_num, @new_mem_set=mem_set, @new_lname=lname, @new_fname=fname, @new_report_date=report_date, @new_total_certs=total_certs 
    FROM inserted; 

    SELECT @count_rec = COUNT (*) FROM fuzzy_param_trapezoid WHERE MEM_SET = (SELECT mem_set FROM inserted); 
    --dbms_output.put_line(count_rec); 

    IF(@count_rec = 0) 
    BEGIN --if 
     --update fuzzy attributes of stud_fuzzy_orders_mv 
     SET @new_poor = dbo.FIT.update_certs_poor(@new_stud_num, @new_total_certs, @new_mem_set); 
     SET @new_average = dbo.FIT.update_certs_average(@new_stud_num, @new_total_certs, @new_mem_set); 
     SET @new_excellent = dbo.FIT.update_certs_excellent(@new_stud_num, @new_total_certs, @new_mem_set); 

     INSERT INTO STUD_FUZZY_CERTIFICATIONS values(@new_stud_num,@new_mem_set,@new_lname,@new_fname,@new_report_date, 
       @new_total_certs, dbo.FIT.update_certs_poor(@new_stud_num, @new_total_certs, @new_mem_set), 
       dbo.FIT.update_certs_average(@new_stud_num, @new_total_certs, @new_mem_set), 
       dbo.FIT.update_certs_excellent(@new_stud_num, @new_total_certs, @new_mem_set)); 

     UPDATE STUD_FUZZY_CERTIFICATIONS_mv SET POOR=@new_poor, AVERAGE=@new_average, EXCELLENT=@new_excellent 
     WHERE stud_num=@new_stud_num and mem_set=@new_mem_set; 

    END; 
END;
