Database 2
Contains table called “dbo.aspnet_Users�
Aspnet_Users contains field/column “UserName�
Problem: Whenever a record’s “Username� field is updated in dbo.Users (Database 1), I need to update the “UserName� field in aspnet_Users (Database 2).
How should I write the trigger to accomplish this task?
The following trigger is currently_not_ working. :(
ALTER TRIGGER [trig_updateUserNameForForum]
ON [dbo].[Users]
FOR UPDATE
AS
DECLARE @oldUserName NVARCHAR(256)
DECLARE @newUserName NVARCHAR(256)
IF UPDATE(Username)
BEGIN
SELECT @oldUserName = (SELECT Username FROM Deleted)
SELECT @newUserName = (SELECT Username FROM Inserted)
UPDATE Database2.dbo.aspnet_Users
SET Username = @newUsername WHERE UserName = @oldUserName
RETURN
END
Hi Iam trying to do a trigger that everytime I Update a record de date get update too I finally find a trigger close to that, but this trigger update all the dates from all the record of the same table I wonder is there are a way that I can do it by the date of the record, if somebody could help I will really appreciate.
Thi is the trigger that I have so far
Create Trigger Update_Date on DBO.Company After Update as Update dbo.Company Set ActualiizationDate=Getdate() go
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
Are there any limitations or gotchas to updating the same table whichfired a trigger from within the trigger?Some example code below. Hmmm....

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?
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?
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 have an update trigger which fires from a transactiion table to update a parent record in another table. I am getting no errors, but also no update. Any help appreciated (see script below)
create trigger tr_cmsUpdt_meds on dbo.medisp for UPDATE as

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

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)
I am hoping someone can shed light on this odd behavior I am seeing running a simple UPDATE statement on a table in SQL Server 2000. I have 2 tables - call them Table1 and Table2 for now (among many) that need to have certain columns updated as part of a single transaction process. Each of the tables has many columns. I have purposely limited the target column for updating to only ONE of the columns in trying to isolate the issue. In one case the UPDATE runs fine against Table1... at runtime in code and as a manual query when run in QueryAnalyzer or in the Query window of SSManagementStudio - either way it works fine. However, when I run the UPDATE statement against Table2 - at runtime I get rowsaffected = 0 which of course forces the code to throw an Exception (logically). When I take out the SQL stmt and run it manually in Query Analyzer, it runs BUT this is the output seen in the results pane... (0 row(s) affected) (1 row(s) affected) How does on get 2 answers for one query like this...I have never seen such behavior and it is a real frustration ... makes no sense. There is only ONE row in the table that contains the key field passed in and it is the same key field value on the other table Table1 where the SQL returns only ONE message (the one you expect) (1 row(s) affected) If anyone has any ideas where to look next, I'd appreciate it. Thanks
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?
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.
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
I am new to this and on my way to learning. I hope someone can help me with a trigger. I want to update status of one table when I insert a new threat in another. This is what I have come up with so far.

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.

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???
these columns can allow nulls. What i whant to do with my trigger is do a after trigger and check after the load if a certain column is NULL place a X instead like a flag but only on the columns that are NULL how would i do this.
Is there a way I can get the old value of a specific field when using an update trigger? e.g. I want to use the condition 'If Update(Column) ' in odrer to create a logfile which stores the old and new value of a field. The new value can be get from a Select from Inserted table. Is there a way I can get the old value (before update) also??
I have created a table with the following columns Jobnumber varchar(20), weight real(4), freightcost money(8), trackingnumber vchar(50), comments varchar(2000) and voidid varchar(3)

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
The EMPLOYEE table holds all the basic stuff you would want to know about an employee and it contains a STORE_CODE attribute that points to the same attribute in the STORE table (to keep track of the store they work at). The STORE table has the STORE_CODE attribute, a NUM_EMP attribute that keeps track of the number of employees at that store, and some other information that is of no relevance to the question.
I've written the following TRIGGER to update the NUM_EMP attribute in STORE everytime a row is inserted or deleted from EMPLOYEE. It works fine for inserts and deletes but I am clueless as how to make it work for updates (an EMPLOYEE transfers to another store). I appreciate any feedback and please feel free to tell where I've gone wrong so far.
Thanks!

This is something I have limited experience on. I need to create an update trigger after insert on one table that updates a completely different production table. My development server is being re-done and I'm not sure when it will be back on line. I have created some audit tables using triggers but they a simple inserts into a new table.
I believe the trigger statement should look like this, any advice would be appreciated.
Thanks in advance.

If I have a situation where a particular SQL statement updates three records on a table and there is an Update trigger defined on the table, then how many times will the trigger fire - three times or one time.
CREATE trigger CT_EB_EpromBestanden on dbo.EB_Eprom after update as update EB_Eprom set eb_eprom.bestand_1 = '../data/'+str(b.bestand_1) , eb_eprom.bestand_2 = '../data/'+str(b.bestand_2) from EB_Eprom a join inserted b on a.EpromID= b.EpromID
the thing that this trigger must do is update the given value with the custom path ../data/

I'm trying to write an update trigger on sql 2005 but having a few issues. Basically I have a table with say 10 records in there. When an update occurs on a record and I want the trigger to recognise this and place a flag of X in a column to mark it.
The trigger then copies the record marked with X into another table. In the source table where the flag is marked X it will then update it with a GetDate function.
Can someone advise what I'm doing stupidly wrong. I want a before update function. But I'm getting an error on the Before Syntax. Any advise/help appreciated
