Problem In Update Trigger In SQL Server 7.0 - Need Some Help!
Jul 23, 2005
Hi for all on this...
I'm using MS SQL Server 7.0 SP4 in some customers to store some data
from an aplication developed by me.
I created an trigger to run on update.
When I run an update command on it's table and the where condition
returns only one row, the trigger is executed ok, but if where
condition returns more than one rows, the trigger don't run.
I don't know what happens there...
If any can help on this, I will be thankfull!
Regards!

Hi all,
I have a trigger for column eISBNEnteredDate on update or insert changes of eISBN of the table Products2 ( both belong to the same table). The column eISBNEnteredDate can either be added manually along with eISBN value or when only eISBN value is entered it is updated with present date.
The problem I am facing is when I send eISBN along with eISBNEnteredDate the present date is what is getting saved. Upon the same record when a new date is updated the new date is getting saved. Can someone tell me where I am going wrong?
Here is my trigger:
Code Block
ALTER TRIGGER [dbo].[Products2_eISBNEnteredDate] ON [dbo].[Products2]
For Insert, Update
As
Begin
Declare @ProductId int
Declare @eISBN Varchar(17)
Set @eISBN = '0'
If ( Update(eISBN) )
Begin
Select @Productid = I.Productid,@eISBN = I.eISBN
From Inserted I Left Join Deleted d on I.Productid = D.Productid
Left join Products2 P on P.Productid = I.Productid
Where (ISNULL(I.eISBN,'') <> ISNULL(D.eISBN,''))
If (IsNull(@eISBN,'') <> '' and IsNull(@eISBN,'') <> '0')
Begin
Update Products2
Set eISBNEnteredDate = getdate()
Where ProductID in (select i.ProductID
From Inserted i
Left join Deleted d on d.ProductID = i.ProductID
Where (i.eISBN is not null or replace(i.eISBN,' ','') != '') --where the new eISBN is not null or blank
and (d.eISBN is null or replace(d.eISBN,' ','') = '') --where the old eISBN is null or blank
and isnull(i.eISBN,'') != isnull(d.eISBN,'') --where the new eISBN is not equal to the old ISBN13
and d.eISBNEnteredDate is null)
End
If IsNull(@eISBN,'') = '' and IsNull(@eISBN,'') = ''
Begin
Update Products2
set eISBNEnteredDate = NULL
Where ProductID = @Productid
End
End
End

We have an UPDATE trigger that is failing. This seems like a basic task - we want to write a record to a separate tracking table when our main transaction table is updated for any reason. Our assumption is that we have a reference to the data from the "inserted" record that was just updated. The scenario here is that we are running a batch process which READS several thousand records in our transaction table each evening.
We then mark each individual record as processed on the transaction table and expect that the UPDATE trigger will successfully fire (it is not). The version of our trigger listed below shows our attempt to deal with the fact that TransactionID does NOT exist from "inserted." We also have a version of this trigger that deals with INSERTS - it works flawlessly.
ON [dbo].[FPS_Transaction]
AFTER UPDATE
AS declare @trxId uniqueidentifier;
BEGIN TRY
SET NOCOUNT ON
[code]...

We have a database on a 2005 box, which we need to keep in sync with one on a 2014 box (until we can turn off the one on 2005). The 2005 database is still being updated with changes that must be applied to the 2014 database, given the nature of the data (medical documents) we need to ensure updates are applied to the 2014 database in very near real time (these changes are - for example - statuses, not the documents themselves).
Cunning plan #1, ulgy - not at all a fan of triggers - but use an after update trigger to run a sp on the remote box via a linked server in this format, with a SQL Server login for the linked server with permissions to EXEC the remote proc.
CREATE TRIGGER [dbo].[SourceUpdate] ON [dbo].[SourceTable]
AFTER UPDATE
AS
SET XACT_ABORT ON;
SET NOCOUNT ON;
IF UPDATE(ColumnName)
[Code] ....
However, while the sp can be run against the linked server as a standalone query OK, when running it in a trigger it's throwing
OLE DB provider "SQLNCLI" for linked server "WIBBLE" returned message "The transaction manager has disabled its support for remote/network transactions.".
Msg 7391, Level 16, State 2, Procedure TheAfterUpdateTrigger, Line 19
The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "WIBBLE" was unable to begin a distributed transaction.
Whether it actually possible to call a proc on a remote box via a trigger and if so what additional hoops need to be jumped through (like I said, it'll run OK called via SSMS)?

I am writing a trigger for getting values to auditlog table when the values gets updated. Below is the code of my trigger.
CREATE TRIGGER [dbo].[Update_Temp] ON [dbo].[Temptable1] FOR UPDATE
AS
DECLARE @bit INT ,
@field INT ,
@maxfield INT ,
@char INT ,
@fieldname VARCHAR(128) ,
@TableName VARCHAR(128) ,
[Code] ....
The code is working fine when the table has primary key associated. However due to some restrictions I will not be able to have a primary key for some tables. I want to implement the same trigger in those tables too. When there is primary key, that primary key needs to get inserted into the audit table and if there is no primary key, i want a specific column value to get inserted instead of the primary key value into the audit table.
For example, i have a student table in which there is a student id, name, dob. there is no primary key defined for the table. So when i update the name or dob, i need the student id to get inserted into the Pk column of the audit table.
I tried modifying the code by checking the @pkcols for Null and if its null to get the old value as the primary key however I was not able to do it .

hi!
I have a big problem. If anyone can help.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
Is there any other way to do this?
can DBCC help to retrieve this info?
Please advise me how to do this.
Thanks in advance.

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?

I have a situation where I have Table A, Table B.
View C is created by joining table A and table B.
I have written a instead of trigger D on view C.
I do not insert/update/delete on the view directly.
For every insert/update in table A /B the values should get insert/update in the view respectively. This insert/update on view should invoke the trigger.
And I am unable to see this trigger work on the view if any insert/update occurs on base table level.
Trigger is working only if any operation is done directly on the view.

Hi,
I am not sure if this is the right forum to post this question.
I run an update statement like "Update mytable set status='S' " on the SQL 2005 management Studio.
When I run "select * from mytable" for a few seconds all status = "S". After a few seconds all status turn to "H".
This is a behaviour when you have an update trigger for the table. But I don't see any triggers under this table.
What else would cause the database automatically change my update?
Could there be any other place I should look for an update trigger on this table?
Thanks,

I am trying to update a fields with an UPDATE statement but I keep getting the error message when I run the query.
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
I have this Update trigger that I know is causing the error message because I guess it's not built to manage multi-row updates.
Can someone help me re-write it. I also tried using the WHERE p.ID = p.ID but when I do that it modifies all rows in the modifieddate column instead of just the cells/rows that I'm updating
ALTER TRIGGER [dbo].[MultitrigCA]
ON [dbo].[ProdDesc]
AFTER UPDATE
AS
SET NOCOUNT ON
IF UPDATE (codeabbreviation)
UPDATE p
sET p.ModifiedDate = GETDATE()
FROM ProdDesc AS p
WHERE p.ID = (SELECT ID FROM inserted)

hi!
i have a database with about 20 tables. i appended to each table a column "UpdatedOn", and i want to write a trigger to set the date of the update date in that column, using a trigger.
i want to avoid the trigger launching for the last column (UpdatedOn).
how can i detect the rows that changed, and modify only the update date/time?
i read something about TableName_Inserted and TableName_Deleted, but i would prefer to copy as generic as possible the data from there, meaning, not to write column names in my script.
another idea i thought about was to prevent the trigger executing if no other column except for UpdatedOn changed, but... i encounter some trouble, when i try to pass column name (as string) to UPDATE() function.(Error: Expecting ID or QUOTED_ID)
thank you in advance.

Hello All,
I've been adviced without much detail that the best way to handle updates is with an Update Trigger to write to an AuditTable.
I always thought it was better to avoid triggers.
I'm getting confused very fast in reading about triggers.
Could someone please point me in the right direction?
Thank you,
Tina

i am using address table to store the address of employees, agents, students; so can't use cascade update and delete. so i decided to use trigger but i got stuck here as well.
Here employeeid is the PK of employee id. so when it is updated, i want to update that id in corresponding address table as well.
so what i need is to find out the previous value of EmployeeID before updating to use in WHERE clause and new EmployeeID to use in SET clause.
<code>
CREATE TRIGGER [AddressUpdate] ON [dbo].[MCS_Employee]
FOR UPDATE
AS
IF UPDATE(EmployeeID)
BEGIN
UPDATE MCS_Address SET EmployeeID = 'i am stuck here; how to know the previous value?
WHERE EmployeeID = ???
END
</end>
ironically, PK in my table can be updateable as well.

Hello all. I have a table which is the exact replication of a different table. Now if an update takes place in the original table I want to copy that row into the new table without the update.I have this but I am not sure if it works.Create Trigger Content_Archive on content
For Update
As
Insert Into content_audit Select * From DeletedI dont know if Updated exists so I am using Deleted. It is returning both rows (before and after update). And the insert should take place as soon as an update takes place in any field in the content table.

Hello, I have two tables, looks as follow.
TOPIC
------
TOPIC_ID
STATUS_ID
TOPIC
THREAD
-------
THREAD_ID
TOPIC_ID
STATUS_ID
THREAD
THREAD_DATE
NAME
I want to update STATUS_ID in TOPIC when I post a new THREAD.
I guess the best would be to use a trigger?
Don't know much how you write them so if someone please could help or point me in right direction.
My plan is to always show the updated STATUS_ID in TOPIC while I have history in the THREAD TBL.
I am using MS SQL 7.0
Thanks for a great site.

I HAVE TWO TABLES IN THE DATABSE T1 AND THE SECOND TABLE(T2) IS FOR AUDITING.
THE STRUCTURE OF BOTH THE TABLES IS SIMILAR WITH ONE MORE COLUMN 'STATUS' IN THE T2.
I HAVE ALREADY WRITTEN THE TRIGGERS FOR THE INSERT AND DELETE TRIGGERS SO THAT I CAN SAVE THE
RECORD WITH STATUS OF 'NEW INSERT' OR 'DELETE' OR 'UPDATE' IN THE AUDIT TABLE(T2).
HELP ME IN WRITING THE TRIGGER FOR UPDATE.
MY PROBLEM IS I DON'T KNOW HOW TO STORE THE UPDATED COLUMNS VALUES INTO VARIABLES AND SO THAT
I CAN STORE THE OLD VALUES INTO THE AUDIT TABLE(T2).
I M USING SQL SERVER 6.5, SO WE CAN NOT USE COLUMNS_UPDATED() IN THE TRIGGER.
PLEASE SUGGEST ME THE CODE SO THAT I CAN STORE THE OLD ROW IN THE TABLE(T1) TO TABLE (T2)
WITH STATUS 'UPDATE' IN THE T2.
PLEASE SUGGEST ME..ITS URGENT.
THANKS IN ADVANCE

I have an update trigger on a table on my transactional database that inserts a row of data into another database (audit database)for any modification made on the transactional database.
So if i modify a row on tran db it will write the data modified as a new row in the audit db.
This works fine if I am updating only 1 row with each Update statement. However if I update more than 1 row (multiple rows) with the same Update statement, the update trigger only inserts the last row modified in the audit database. So I lose record of any other rows modified with the same update statement.
Is there a way by which i can change my Update trigger or something, so I get all the rows updated by 1 update statement inmy audit database???
Thanks a bunch,
Judy

Hallo there,
I'm totally new to writing triggers, but managed to get a trigger to update a specific column (ufINCTcost) on change of another column (ufINCKm)
My problem is that the trigger performs this update on ALL rows, which makes it very slow. How can I get it to only update the column on the row where the change was made ?
My trigger looks as follows:
CREATE TRIGGER updateincidents ON [dbo].[_rtblIncidents]
FOR UPDATE, INSERT
AS
IF UPDATE (ufINCKm)
BEGIN
UPDATE dbo._rtblIncidents
SET ufINCTcost=dbo._rtblIncidents.ufINCKm+dbo._rtblInc idents.ufINCToll+dbo._rtblIncidents.ufINCParking+d bo._rtblIncidents.ufINCFlight+dbo._rtblIncidents.u fINCRental
Hope you can help !!
