Triggers Per Row Not Per Statement

Sep 14, 2007

Hi guys



I am wondering if there is any way of setting the trigger to execute once per individual row that is updated as appose to once per statement. Thus a statement like this would trigger twice not just once:


Update Order

Set Name = 'test'

Where OrderId In (1,2)



If this is not possible do the Deleted and Inserted tables have the records for all the items that were updated in the statement?



The reason being that i need to store the before snapshot and after snapshot of the updated data in an audit database along with an event that ties the two audit records together. This event is a business logic event, which is stored in the main database and records which user made the change, what other records the change is related to and impacts, etc, etc. Thus after the above update is complete, I would have 4 audit records, 2 being pre shots and 2 being post shots, along with 2 event records. Where each event record ties one of the pairs of pre and post audit records together.





Now if the tables hold all the records, my first thought was to simply do a mass insert. But as the event ties the pairs of pre and post records together I can€™t just do a mass inset into the database. Thus when I first thought about doing this row by row triggers is great for me as it keeps the logic fairly simple. But if i only get one bit of the apple (as it were) does anyone have any suggestions as to about I could go about. Is my only option to run through a cursor on the inner join of the pre and the post data and on each loop create my event and then insert the pre and post shots??



Any help is appreciated.

Triggers For Select Statement

We have triggers for Insert, Update and Delete, so that we can check which record is going to inserted, updated or Deleted.

Is there any way so that we could check "From which values the data has been selected ?"

ODBC Prepared Statement And Triggers

Nov 3, 2002

I have an application which uses ODBC to insert, update, delete records in an MSSQL DB. The application uses prepared statements and keeps the odbc statement handles to execute the same statement multiple times.
This application works fine until triggers are introduced. The triggers are pretty simple and take the inserted, updated record and insert this information into another table.
If we change the application to not re-use the prepared statement handle, by closing the statement handle after each execute, it also works fine. (However, this results in bad performance.)

The error message is: "[ODBC SQL Server Driver]Connection is busy with results for another hstmt". If anyone has any information on this, I would greatly appreciate the help!!!

Thank you.

Multiple Triggers On A Table Or Encapsulated Triggers

May 12, 2008

This isn€™t an problem as such, it€™s more of a debate.

If a table needs a number of update triggers which do differing tasks, should these triggers be separated out or encapsulated into one all encompassing trigger. Speaking in terms of performance, it doesn€™t make much of an improvement doing either depending upon the tasks performed. I was wondering in terms of maintenance and best practice etc. My view is that if the triggers do totally differing tasks they should be a trigger each on their own.

Multiple Tables Used In Select Statement Makes My Update Statement Not Work?

Aug 29, 2006

I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly.  My problem is that the table I am pulling data from is mainly foreign keys.  So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys.  I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit.  I run the "test query" and everything I need shows up as I want it.  I then go back to the gridview and change the fields which are foreign keys to templates.  When I edit the templates I bind the field that contains the string value of the given foreign key to the template.  This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value.  So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors.  I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode.  I make my changes and then select "update."  When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing.  The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work.  When I remove all of my JOIN's and go back to foreign keys and one table the update works again.  Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People].  My WHERE is based on a control that I use to select a person from a drop down list.  If I run the test query for the update while setting up my data source the query will update the record in the database.  It is when I try to make the update from the gridview that the data is not changed.  If anything is not clear please let me know and I will clarify as much as I can.  This is my first project using ASP and working with databases so I am completely learning as I go.  I took some database courses in college but I have never interacted with them with a web based front end.  Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

SQL Server 2012 :: Create Dynamic Update Statement Based On Return Values In Select Statement

Jan 9, 2015

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".

Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

TSQL - Use ORDER BY Statement Without Insertin The Field Name Into The SELECT Statement

Oct 29, 2007

Hi guys,
I have the query below (running okay):



Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
FROM myTables
WHERE Conditions are true
ORDER BY Field01

The results are just as I need:


Field01 Field02

------------- ----------------------

192473 8461760

192474 22810



Because other reasons. I need to modify that query to:



Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
INTO AuxiliaryTable
FROM myTables
WHERE Conditions are true
ORDER BY Field01
SELECT DISTINCT [Field02] FROM AuxTable
The the results are:

Field02

----------------------

22810
8461760

And what I need is (without showing any other field):

Field02

----------------------

8461760
22810


Is there any good suggestion?
Thanks in advance for any help,

Triggers

Jan 3, 2007

Is it possible to achieve this using triggers:When someone tries to delete a row in table A, the trigger should first delete a corresponding row in table B and then delete the row in table A. The reason being that, there is a foreign key set on Table B that references table A. So any attempt to delete a row in table A without deleting the corresponding row from B, throws an error.

Triggers - Is This Possible?

Jun 15, 2007

I need to create a set of rows every time a new row is inserted into a table.
Example (I think this would work)...
select @insertedId = column1 from insertedselect @id = column1 from table1 where column2 in (select column1 from table2 where column2 = @insertedId)insert into table3 values(x, y, @id)
Is it possible to do the same kind of thing in a situation where the select statement returns multiple values and execute the insert statement for each of these values?
Also, if table3 was in fact the table on which the trigger acts, would it then be executed for every row created by the trigger?
Sorry if I sound confused. I am.

Hi All,
I'm using triggers to handle my transaction log to cature inserts and updates. It works fine except if the user clicks on the Save button more than once, the trigger is fired and the record is written to the log even if the record wasn't changed. Does anyone know how to check if the record was actually changed so that it isn't written to the table if it wasn't?

Thank you,

SQL Triggers

Jun 17, 2004

When I execute a stored proc from my asp.net page, will the results of a trigger be returned to my program?

For instance say my stored proc is:

Update Employees set
(Lastname = @Lastname)
where ID = @ID

And my trigger is:

CREATE TRIGGER tr_Employees_U on Employees FOR UPDATE AS
IF UPDATE(lastname)
BEGIN
RAISERROR ('cannot change lastname', 16, 1)
ROLLBACK TRAN
RETURN
END
GO


It seems like since this is an AFTER trigger that my webpage would actually get a valid return code from my stored procedure however the trigger would rollback those changes correct? Or would the trigger get fired and send it's return code to my webpage?

I'm a bit confused on this bit please elaborate : " FROM Test_TRG t INNER JOIN inserted i ON t.PK = i.PK ".
The PK is on which field? Basically this trigger should ensure that on insertion of o new loan if
The left(loan_no,3)=MCG and its null then NEWMCG
left(loan_no,3)=MCG and its null then NEWMCG
left(loan_no,3)=KVS and its null then NEWKVS
left(loan_no,3)=MFS and its null then MFS
left(loan_no,3)=TCR and its null then TCR
left(loan_no,3)=ABL and its null then ABL

Listed below is what l've tried to do but l'm missing the PK part.Otherwise everything else you explained
in the script is clear. Thanks man its urgent. When l parse the query its fine , but When l run it
l get an error.



CREATE TRIGGER UpdTest_TRGData
ON Test_TRG
FOR INSERT, UPDATE
AS

UPDATE Test_TRG
SET LoanBook = CASE WHEN LEFT( i.Loan_No, 3 ) = 'MCG' THEN 'NewMCG'
WHEN LEFT( i.Loan_No, 3 ) = 'KVS' AND i.LoanBook IS NULL THEN 'NewKVS'
WHEN LEFT( i.Loan_No, 3 ) = 'MFS' AND i.LoanBook IS NULL THEN 'MFS'
WHEN LEFT( i.Loan_No, 3 ) = 'ABL' AND i.LoanBook IS NULL THEN 'ABL'

WHEN i.LoanBook IS NULL THEN LEFT( i.Loan_No, 3 )
END
FROM Test_TRG t INNER JOIN inserted i ON t.PK = i.PK
-- Fill in Primary Key or other Join Column(s)

Hey everyone...

I'm working on trying to figure out how to update the child table from the parent via a trigger. This works fine as long as the value is in the child table. If it's not, then I get my foreign key violation. So, My next thought was to simply put in a begin tran / rollback tran within the trigger... My question is this : If I have multiple triggers on the parent table all based on the update of the key field (and the child tables... some 7 of them) all have FK's, if I rollback one trigger does it rollback the entire transaction? Or just the functionality of that trigger? From what I've read, it appears as if it's the entire transaction... if so, how do I get a trigger to 'ignore' itself or not fire based on a select criteria that i have within that same trigger...

Thank you...

Oct 24, 2001

I just tried creating my first trigger and I'm a little bit confused. I am trying to see if certain fields have changed and will do that by checking the values of the fields in the "master" table and the "Inserted" table. I wasn't sure which table would have the old data and which would have the new, so I created the following trigger to help me determine which was which:

CREATE Trigger upd_cost_master On tbl_cost_master
For Insert, Update As

Declare @U_Name varchar(65)
Declare @O_Name varchar(65)

Select @U_Name=I.submitted_by, @O_Name=O.submitted_by
From tbl_cost_master O Inner Join Inserted I On O.autokey = I.autokey

Print 'Inserted: ' + @U_Name
Print 'tbl_cost_master: ' + @O_Name

Commit Tran

To my surprise, @U_Name and @O_Name contained the same values. I though that one table contained the old values and one contained the new. Was I wrong? If so, is there anyway to compare the Old and New values through a trigger?

Hi,

I'm using SQL Server 7.0. I have an insert trigger on table t05r. I populate table t05r with a DTS package. The trigger is supposed to add the record which was inserted into t05r, into t39r. After I run the DTS package to populate t05r, I checked t39r and no records where added. What is going wrong? Is it that DTS uses bulk copy and triggers don't fire on bulk copy?

Any help would be greatly appreciated.
