Transact SQL :: After Update Trigger
Aug 27, 2015
I would like to make an after update trigger on a table (ARD TABLE) where depending on the criteria the trigger will either insert, update, or delete a row in the trigger table. Basically, in the trigger table there can only be rows where the column status is > 0. So, if the ARD TABLE has a row updated that used to have a status of 0 and now the status changed to 1 then insert it into the trigger table. If the ARD TABLE had a row that used to be 1 and now it's 0 then delete it from the trigger table. And if the ARD TABLE had a row that was 1 and now made any change to that row we need to update the corresponding row in the trigger table.

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'm updating one column using trigger but i am getting below error .
UPDATE failed because the following SET options have incorrect settings: 'NUMERIC_ROUNDABORT'. Verify that SET options are correct for use with indexed views and/or indexes on computed columns and/or filtered indexes and/or query notifications and/or XML data type methods and/or spatial index operations.

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.

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.

Is there any way that I can execute a command after a database is restored? I need to be able to embed this into the database so that when it's restored on any computer, it updates a value in a table.

I am new in sql server. I am using TSQL2012 database. I have added a new column in processedOrderCount in Hr.Employees table. And created a trigger on Sales.Orders table that whenever orderId is updated it automatically updated processedOrderCount in Hr.Employees. There is a problem that the orderId is the identity column I can't update it. How can we work with identity column? the code of my trigger is:
If Object_id ('Sales.trig_Calculate_OrderProcessed', 'tr') is not null
Drop Trigger Sales.trig_Calculate_OrderProcessed
go
Create Trigger Sales.trig_Calculate_OrderProcessed
ON Sales.Orders

We have to encrypt one of the SQL Server column data at the database level, we don’t want to modify the application programs, because we use ERP application and we don’t want to reapply our customization very few months, so we are looking for an option to encrypt and decrypt the column level data value using trigger/procedure/function, I used instead of trigger on that table to encrypt and decrypt the values but it is not working, we want only one user(Application Service account) have an ability to encrypt and decrypt the data, not for any other id.. I read somewhere we cannot automatically encrypt/decrypt the column value using trigger, is that true...

I have a table which has a recursive relationship to its self neither of the columns involved are FK columns
CREATE TABLE [dbo].[ix_Trace](
[Trace_Id] [uniqueidentifier] NOT NULL,
[Trace_BubbledTraceEnter_Id] [uniqueidentifier] NULL,
[Trace_EnterId] [uniqueidentifier] NULL,
[Trace_Application_Id] [uniqueidentifier] NULL,
[Trace_Session_Id] [uniqueidentifier] NULL,
....
Where Trace_EnterId is the parent ID and BubbledTraceEnter_Id is the child ID. My test case has nested trace lines that go down 5 levels, but when I delete the top trace line, only the child directly under it is deleted leaving the other 3 as orphans. Here's the trigger:
ALTER TRIGGER [dbo].[DTrig_xTrace]
ON [dbo].[ix_Trace]
FOR Delete
AS
BEGIN
SET NOCOUNT ON;
DELETE FROM ix_Trace
FROM ix_Trace INNER JOIN
deleted as dt ON ix_Trace.Trace_BubbledTraceEnter_Id = dt.Trace_EnterId
How can I make this cascade all the way down?

SQL Version: SQL2014
PROBLEM: The SQL insert trigger code below is returning incorrect results. In some cases the results returned are from entirely different fields than those specified as the source field in the SET statement. For instance the value returne for the Price_BeforeAdj field does not = 20000000? It returns a NULL. See code below.
OFFENDING CODE:
ALTER TRIGGER [dbo].[xcti_WIPAdjustments_I]
ON [dbo].[budxcWIPAdjustments]
AFTER INSERT AS
BEGIN
SET NOCOUNT ON;
UPDATE budxcWIPAdjustments

I created a view that joins several tables together and added an instead of insert, update trigger on it. My trigger works when I do an update/insert directly to the view, but it doesn't seem to fire when an insert/update is made to any of the tables that the view is based on. Is there a way to have the trigger fire when something happens to the tables that the view is based on? The application that the database is using is something that was purchased so I don't have access to the code to change any SQL statements that it's using.

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
