How To Create Simple Insert Trigger
Oct 31, 2006
I have just one table but need to create a trigger that takes place after an update on the Orders table. I need it to multiply two columns and populate the 3rd column (total cost) with the result as so:
Orders
---------
ProductPrice ProductQuantity TotalCost
-------------- ------------------ -----------
£2.50 2
£1.75 3
£12.99 2
Can anyone please help me?

I have never used triggers before and I have tried to solve one problem. If I have the column "currency" in a table and want to make sure that the entered value i valid in relation to another table that contains valid currency formats, I did it like this:
---------------------------------
CREATE TRIGGER [trigger_checkCurrency] ON [dbo].[Client]
FOR INSERT, UPDATE
AS
declare @currency as char(50)
declare @country as char(50)
declare cur cursor for SELECT currency, country
FROMinserted
OPEN cur
fetch cur into @currency, @country
WHILE @@FETCH_STATUS = 0
BEGIN
if not exists(select * from listinfoid where listname = 'currency' and listid = @currency)
begin
set @currency = (cast(@currency as varchar (3)) + ' is not a valid currency')
CLOSE cur
DEALLOCATE cur
RAISERROR (@currency,16,-1) with log
return
end
if not exists(select * from listinfoid where listname = 'country' and listid = @country)
begin
set @country = (cast(@country as varchar (3)) + ' is not a valid contry')
CLOSE cur
DEALLOCATE cur
RAISERROR (@country,16,-1) with log
return
end
else
fetch cur into @currency, @country
END
CLOSE cur
DEALLOCATE cur
update Client set currency = UPPER(currency), country = UPPER(country)
---------------------------------
I use a cursor to handle multiple rows in an update query.
(SQL2000-server)
Is there an easier och better way to do this?
I´m a bit unsure of this code.
Thanx!

I want to be able to create a trigger so that when a row is inserted into table A by a specific user then the ID will appear in table B. Is it possible to find out the login id of the user inserting a row?
I believe the trigger should look something like this:
create trigger test_trigger
on a
for insert
as
insert into b(ID)
select i.id
from inserted i

Should i create only one trigger for each table and put all the table functionality in that one trigger?
For example: tr_tblCategory, tr_tblQuestion, tr_tblAnswer
Or should i create a different trigger for each different function on that table?
For example: trReviseDate, trDoThis, trDoThat, trVerifyThis
Is there a better practice in this area?
What do you typically do?
Thanks!

I do not know if I am in the proper thread, if not thnaks to let me know where to post it..
I have a runing table name CURENTALARM which strore different alarm information.
This table has a Column named STATUS.. When the new inserted rows ocurrs and STATUS =1, then I need to copy that row in a new table name STATUSLOG...
For that I have created a trigger for table CURENTALARM and then do proper commands to insert to other table.
I am using the inserted table in my trigger to fetch last inserted rows.
The question I have is that how to guaranty that each inserted row will fire the triggers properly...
What I mean is that in case I have 2 rows which gets inserted within less than a second in time interval, does the triggers will be able to do its job and proceed properly inserted row or is there a situation that when rows gets inserted too fast, the triger might miss some of them ?
If this is the case how to handl that case
thanks for your reply

Hi all, I have a problem with this trigger. It seams to be very simple, but it doesn't work...
I created a trigger on a table and I would want that this one updates a field of a table on a diffrent DB (Intranet). When I test it normally (a real situation), it doesn't work, but when I do an explicit update ("UPDATE AccesCard SET LastMove = getDate();" by example) it works.
If anyone could help me, I would appreciate.
NB: Is there a special way, in a trigger, to update a table when the table to update is on another BD ?
Francois
This is the trigger:
------------------------------------------------------------
ALTER TRIGGER UStatus
ON AccesCard
AFTER UPDATE, INSERT
AS
DECLARE @noPerson int
SET NOCOUNT OFF
IF UPDATE(LastMove)
BEGIN
SELECT @noPerson = Person FROM INSERTED
UPDATE Intranet.dbo._Users SET Intranet.dbo._Users.status = 1 WHERE personNo = @noPerson;
END
SET NOCOUNT ON

Experts: Please assist with coding a trigger for a SQL Server 2005 .NET application.
Here's the scenario:
Suppose there are tables MEMBERS, ACTIVITY, and HEADCOUNT that look like this:
MEMBER
member_id (int)
member_name (varchar(50))
...etc
ACTIVITY
activity_id (int)
activity_name (varchar(50))
...etc
HEADCOUNT
headcount_id (int)
member_id (int)
activity_id (int)
...etc
Suppose also that the ACTIVITY table is already populated with several records, say with activity_id = 1, 2, and 3.
OBJECTIVE: When a new member record is added to MEMBER, say member_id 10, insert one record in the HEADCOUNT table for EACH activity in ACTIVITY for that member. Thus, if member #10 is added to MEMBER, then the trigger (or some other mechanism) would add the following records to HEADCOUNT (which, say, already has 30 records):
headcount_id member_id activity_id
31 10 1
32 10 2
33 10 3
I've been advised that a trigger should do the trick for this, but as I'm totally new to SQL, I'll need some help. I'm guessing some iterating SQL command language might be required, but as I'm new to SQL, I don't know how to proceed.
Note that I'm building an ASP.NET application based on VB, and so records will be added to MEMBER through a tableadapter INSERT command. (Though I suspect this has no bearing on trigger behavior.)
Much obliged for your assistance.

Hi,We have been using ADO and the AddNew method for a long time as a meansto add records to the database. It has always worked fine - no problem.But - we recently started using INSERT triggers that simply call a fewstored procs (they're actually SSNS stored procs that send new eventinfo to notification services). Anyway, these triggers do not seem tofire at all! If I execute an insert command manually from QueryAnalyser, no problems. But the trigger does not fire at all from myapplication!Does anyone know why this could be? For info, my connection string usedby the ADO connection object looks like this: Provider=SQLOLEDB.1;DataSource=XXX;Initial Catalog=YYYAnd my AddRecord ADO code looks like this:With rs.Open sSQL, ConnectionString, adOpenKeyset, adLockOptimistic,adCmdTable And adExecuteNoRecords.AddNewAm I mnissing something obvious here? Any help appreciated!

This problem is being seen on SQL 2005 SP2 + cumulative update 4
I am currently successfully using the output clause of an insert statement to return the identity values for inserted rows into a table variable
I now need to add an "instead of insert" trigger to the table that is the subject of the insert.
As soon as I add the "instead of insert" trigger, the output clause on the insert statement does not return any data - although the insert completes successfully. As a result I am not able to obtain the identities of the inserted rows
Note that @@identity would return the correct value in the test repro below - but this is not a viable option as the table in question will be merge replicated and @@identity will return the identity value of a replication metadata table rather than the identity of the row inserted into my_table
Note also that in the test repro, the "instead of insert" trigger actually does nothing apart from the default insert, but the real world trigger has additional code.
To run the repro below - select each of the sections below in turn and execute them
1) Create the table
2) Create the trigger
3) Do the insert - note that table variable contains a row with column value zero - it should contain the @@identity value
4) Drop the trigger
5) Re-run the insert from 3) - note that table variable is now correctly populated with the @@identity value in the row
I need the behaviour to be correct when the trigger is present
Any thoughts would be much appreciated

Hello,
I have a search form in an ASP.NET/VB page. The form has the input text box and the button "search". The keywords are passed in the URL to results.aspx.
Here is an example of what I get in the URL, when I write the keywords "asp", "book" and "london" in the input text box and click "search":
results.aspx?search=asp%20book%20london
The database table has 3 fields: "id", "title" and "description".
I want to display all the records where at least one of the keywords is found in any of the 2 fields "title" and "description".
1. I suppose I need to get the words out of the URL to be used by SQL.
Maybe: string[] searchString = request.queryString("search").split('search'); ???
How can i make this run when page loads? I supose i need it. Right?
2. How should the SQL look? I supose i need to use the "Like" command
SELECT * FROM books WHERE title LIKE ...
But how to I use it if I can have 1, 2, 3, ... keywords?
Can someone help me?
Thanks,
Miguel

Hi
I use SQL code snippet to attach the CLR assembly (dll) to the SQL Server Express
CREATE ASSEMBLY [DatabaseAndImages]
AUTHORIZATION [dbo]
FROM 'C:CLR_File.dll'
WITH PERMISSION_SET = SAFE
That file content CRL Codes for 10 Stored Procedures & 3 UDT & 5 Functions & 6 Triggers
As you can see it's content large amount of DB objects !!
My Question is ..
Is there any simple way can I use it to extract or automatic create all that Objects in the Database without use separate SQL Statement for each one ??
By Example , I will use this SQL statement to create the sp_AddImage that already located inside the CLR dll file
CREATE PROCEDURE [dbo].[sp_AddImage]
@ImageID [uniqueidentifier],
@ImageFileName [nvarchar](max),
@Image [varbinary](max)
WITH EXECUTE AS CALLER
AS
EXTERNAL NAME [DatabaseAndImages].[StoredProcedures].[sp_AddImage]
But as you know .. I have many objects .. and I am in development phase and I will do change to that object many time and also may I will add much more €¦
I thing it's not good to write SQL Statement for each object and do changes every time when I change the object definition
Is there any one line of SQL statement can I use it to automatically create and extract all the objects inside the assembly ??
Or is there any way to do that Issue by simple operation ??
And thanks with my best regarding
Fraas
