i got a little problem. when i insert values into a table a trigger is launched wich updates something in the table too.
CREATE TRIGGER T1 ON Tbl FOR INSERT AS BEGIN IF (UPPER(USER) <> 'CONVERSIE') BEGIN UPDATE Tbl SET Datum = GetDate(), User = USER, WHERE Tbl.ID= (SELECT ID FROM inserted) END END
the error i receive is this: 'can not update identity column id' (id being pk).
I need to create trigger on table which will not allow to update value "1" into column and if tried to update.. then it should show error massage "Good To GO"
ID Name Roll 1 Ron 1 2 Jon 0 3 Nil 3 4 Par 1
if you try to update value "1" in Roll then it will through error
I am new to triggers and surely could use some help.
I can create a trigger to insert related records based on the main tables ID and insert that value into other related tables fine... but...
How do I create a trigger that can insert a record into one table for a columns given value and then insert a record into another table for another given value?
For instance: New row...
Table1, Column1 (PK) has a value of 101 Table1, Column2 has a value of 'Blue'.
// When a new row is created in Table1 and Column2 has a value of 'Blue'... I want to insert a new row into Table2 - with Table1 Column1's value.
// Now if Table1, Column2 has a value of 'Red' when the new row was created... I want to insert a new row into Table3 - with Table1 Column1's value. Not Table2
This has to be inserted into one or the other tables based on column2's value, not both. Then I want to populate the other related tables (Table4, Table5) with the regular insert statements based on Table1 Column1's value.
This (the conditional part above) has to work with an update to Table1 also. So if someone came back to that record and changed Column2's value from 'Blue' to 'Red', it would have to delete the appropriate record in Table2 and then insert the new row into Table3 and visa-versa.
I'm hoping someone can help with with a task I've been given. I need to write a trigger which will act effectively as a method of automatically distributing of incoming call ticket records. See DDL below for creation of the Assignment table, which holds information on the call ticket workload.
SELECT COUNT(CallID) AS [Total Calls], AssignmentGroup, Assignee FROM #Assignment GROUP BY AssignmentGroup, Assignee ORDER BY COUNT(CallID) DESC , AssignmentGroup, Assignee
What I need to do is write a trigger for on INSERT to automatically update the Assignee column with the name of the person who currently has the least active calls. For example, using the data above, the next PC Support call will go to Mickey Mouse, and the next two Service Desk calls will go to Jim Smith.
So, the logic for the trigger would be
UPDATE #Assignment SET Assignee = (SELECT Assignee FROM #Assignment WHERE COUNT(CallID) = MIN(COUNT(CallID))
But that's only the logic, and obviously it doesn't work with the syntax being nothing like correct.
Does any one have an idea or pointers as to how I should go about this?
Are there any limitations or gotchas to updating the same table whichfired a trigger from within the trigger?Some example code below. Hmmm.... This example seems to be workingfine so it must be something with my specific schema/code.

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
if update(pstat) begin update med set REC_FLAG = 2 from deleted dt where med.uniq_id = dt.uniq_id and dt.pstat = 2 and dt.spec_flag = 'kop' end
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)

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 have a trigger set on TABLE1 so that any update to this column should set off trigger to write to the AUDIT log table, it works fine otherwise but not the very first time when table1 has null in the column. if i comment out
and i.req_fname <> d.req_fname from the where clause then it works fine the first time too. Seems like null value of the column is messing things up
Any thoughts?
Here is my t-sql

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.
