触发插入/更新如何测试是否插入了某些内容并更新x

Question

我对触发器很新（在上个月之前从未使用它们）。

如何测试是否在一个具有唯一标识符的表中插入行并更新另一个表？

例如：

1   table 1
2   id 1  name max  last: headroom
3   id 2  name john last: sewer<-- newly inserted
4    
5   updated table 2
6   id 1 address: hhhhhhh   initials: m.h.
7   id 2 address: gggggggg  initials: <--update this

这是我更新的方式：

01  CREATE TRIGGER Alabama_ID_UPDATE_USERRWAY ON USERRWAY
02  FOR  UPDATE
03  AS
04  BEGIN
05      SET NOCOUNT ON
06      IF (UPDATE(ST_LOCL_ID))
07      BEGIN
08          DECLARE @BRKEY VARCHAR(15)             
09          SET @BRKEY = (SELECT BRKEY FROM inserted) 
10          DECLARE @ALABAMA_ID VARCHAR(20)
11          SET @ALABAMA_ID = (SELECT ALABAMA_ID FROM USERBRDG WHERE USERBRDG.BRKEY = @BRKEY)  
12                        
13          BEGIN
14              DECLARE @ST_LOCL_ID VARCHAR(4)    
15              SET @ST_LOCL_ID = (SELECT SUBSTRING(USERRWAY.ST_LOCL_ID,1,4)FROM USERRWAY WHERE USERRWAY.BRKEY = @BRKEY AND ON_UNDER = '1')
16          END
17          BEGIN
18              IF(@ALABAMA_ID IS NOT NULL)
19              BEGIN
20                  SET @ALABAMA_ID = STUFF(@ALABAMA_ID, 15, 4, @ST_LOCL_ID)
21                  UPDATE USERBRDG SET USERBRDG.ALABAMA_ID = @ALABAMA_ID WHERE USERBRDG.BRKEY =  @BRKEY
22              END 
23              ELSE
24              BEGIN
25                  SET @ALABAMA_ID = ('XXXXXXXXXXXXXXXXXXX')
26                  SET @ALABAMA_ID = STUFF(@ALABAMA_ID, 15, 4, @ST_LOCL_ID)
27                  UPDATE USERBRDG SET USERBRDG.ALABAMA_ID = @ALABAMA_ID WHERE USERBRDG.BRKEY =  @BRKEY
28              END 
29          END
30      END
31  END
32  GO

我想做的一个例子是：

如果有人在结构单元中插入一行，我需要更新：

UPDATE USERBRDG 
SET USERBRDG.ALABAMA_ID = @ALABAMA_ID 
WHERE USERBRDG.BRKEY = @BRKEY
