sql server - trigger to copy rows from 2 tables - sql

Question

I have a trigger that is called when there's an Update, Insert or Delete on a table that is joined to another table by a PK/FK 1 to 1 relationship.
Currently I'm copying rowX from TableA when a U, I or D occurs. I want it to also copy rowX from TableB at the same time.
How to I do this?
USE [Database]
GO
/****** Object: Trigger [dbo].[archiveTable] Script Date: 14/01/2014 3:48:08 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dbo].[archiveTable] ON [dbo].[TableA]
AFTER INSERT,UPDATE,DELETE
AS
DECLARE #HistoryType char(1) --"I"=insert, "U"=update, "D"=delete
DECLARE #Id INT
SET #HistoryType=NULL
SET #Id=NULL
IF EXISTS (SELECT * FROM INSERTED)
BEGIN
IF EXISTS (SELECT * FROM DELETED)
BEGIN
--UPDATE
SET #HistoryType='U'
END
ELSE
BEGIN
--INSERT
SET #HistoryType='I'
END
--handle insert or update data
INSERT INTO [database2].[dbo].[tableA]
(column1, column2, ...)
SET #Id=INSERTED.column5
SELECT
GETDATE(), #HistoryType,
column1, column2, ...
FROM INSERTED
JOIN tableB ON INSERTED.column5 = table5.column1
INSERT INTO [database2].[dbo].[tableB]
(column1, column2, column3, ...)
SELECT
GETDATE(), #HistoryType,
column1, column2, column3, ....
FROM jobdtl WHERE column1 = INSERTED.column5
END
ELSE IF EXISTS(SELECT * FROM DELETED)
BEGIN
--DELETE
SET #HistoryType='D'
same as above except for delete
END
I'm guessing I need an inner join somewhere or do I need a variable to get the #job_id so it knows to copy the relevant info from the second table?
edit - from the looks of it I need to somehow use SCOPE_IDENTITY() however it's not taking the job_id of the transaction it's taking the actual ID of the transaction (ie. 1, 2, 3, etc. whereas I need it to be dynamic as job_id may be 54, 634, 325, etc.)

Answer 1

To run multiple statements in a trigger, enclose the statements in a BEGIN END block.
You may define multiple triggers for a particular event.
To refer to inserted/updated data, use "inserted" pseudo table. For deleted rows, use "deleted" pseudo table.
It's not clear from your question whether you want to insert into TableA/TableB or if these are the tables for which the triggers are defined. (The SELECT statement lacks a from clause)

Answer 2

I think, you can use the UNION clause to insert two rows from different table at one time.
I have made a demo query you just need to change it to your query.
create table #a
(
id int,
name varchar(10)
)
insert into #a
select 1,'ax'
union
select 1,'bx'
select * from #a
drop table #a
This is just the sample query with the logic, and i hope you understand it.
