Delete Trigger
Nov 5, 2001
hi, I have a table as follow:
id amount
1 100
1 100
1 200
1 300
I put a deleted trigger on this table when a record is deleted, I update a balance in another table based on the deleted amount. This works fine when I am deleting one record at a time, but when I delete more than one record, the first value from the first record is captured to update the balance due and the rest of the of the records has not effect.
To elaborat more,
delete * from table1 where id =1 and amount =200 -- this works fine
delete * from table1 where id =1 and amount =100 -- the first 100 only update the balance in another table the second 100 does nothing,
any ideas, I appreciate your help.
Thanks

I am having great difficulty with cascading deletes, delete triggers and referential integrity.
The database is in First Normal Form.
I have some tables that are child tables with two foreign keyes to two different parent tables, for example:
Table A
/
Table B Table C
/
Table D
So if I try to turn on cascading deletes for A/B, A/C, B/D and C/D relationships, I get an error that I cannot have cascading delete because it would create multiple cascade paths. I do understand why this is happening. If I delete a row in Table A, I want it to delete child rows in Table B and table C, and then child rows in table D as well. But if I delete a row in Table C, I want it to delete child rows in Table D, and if I delete a row in Table B, I want it to also delete child rows in Table D.
SQL sees this as cyclical, because if I delete a row in table A, both table B and table C would try to delete their child rows in table D.
Ok, so I thought, no biggie, I'll just use delete triggers. So I created delete triggers that will delete child rows in table B and table C when deleting a row in table A. Then I created triggers in both Table B and Table C that would delete child rows in Table D.
When I try to delete a row in table A, B or C, I get the error "Delete Statement Conflicted with COLUMN REFERENCE". This does not make sense to me, can anyone explain? I have a trigger in place that should be deleting the child rows before it attempts to delete the parent row...isn't that the whole point of delete triggers?????
This is an example of my delete trigger:
CREATE TRIGGER [DeleteA] ON A
FOR DELETE
AS
Delete from B where MeetingID = ID;
Delete from C where MeetingID = ID;
And then Table B and C both have delete triggers to delete child rows in table D. But it never gets to that point, none of the triggers execute because the above error happens first.
So if I then go into the relationships, and deselect the option for "Enforce relationship for INSERTs and UPDATEs" these triggers all work just fine. Only problem is that now I have no referential integrity and I can simply create unrestrained child rows that do not reference actual foreign keys in the parent table.
So the question is, how do I maintain referential integrity and also have the database delete child rows, keeping in mind that the cascading deletes will not work because of the multiple cascade paths (which are certainly required).
Hope this makes sense...
Thanks,
Josh

Hi,
In Oracle, we have FOR EACH ROW Concept in triggers which can be used to manipulate to fire the trigger for each row.
How can we implement the same in SQL Server 7.0 ?

I have a SQL statement that deletes a lot of records in a table (PACCESOS_DET) and a Trigger that fires for delete on the table.
The Trigger works fine when only one record is deleted but no when more than record is deleted; it only works for 1 and there is no error message.
For each row deleted I need to update a column in another table (PACCESOS_CAB).
This the trigger...
CREATE TRIGGER ActualizaDiasVisita ON dbo.PACCESOS_DET
FOR DELETE
AS
declare @mdias as int
declare @mFKFeria as int
declare @mtipo as char(1)
declare @mfkcontacto as varchar(7)
if exists( select * from PACCESOS_CAB m join deleted i on m.FKFeria= i.FKFeria and m.FKContacto=i.FKContacto and m.Tipo=i.Tipo)
begin
select @mfkferia=m.fkferia, @mfkcontacto = m.fkcontacto, @mtipo = m.tipo, @mdias = diasvisita from PACCESOS_CAB m join deleted i on m.FKFeria= i.FKFeria and m.FKContacto=i.FKContacto and m.Tipo=i.Tipo
update PACCESOS_CAB set diasvisita = @mdias -1 where FKFeria= @mFKFeria and FKContacto=@mFKContacto and Tipo=@mTipo
end
Thanks in advanced.

Although the records are deleting OK, so are the records in Output, which i dont want. i am not sure how to stop this, or to see if my trigger is actually firing, I would appreiciate any suggestions

Hi, I'm building a website that interacts with MS SQLserver(v7) via a Buisiness Rule-layer developed in COM+ with VB(v6 sp5). The website is an add-on on a existing client/server app. Now I have delete triggers on almost every table and they work perfectly in the c/s app and when runned in the query analyzer. But when I try to do the same with COM+ I get the the next error message on line 10:
"Cannot use SAVE TRANSACTION within a distributed transaction."
Here follows the code. Hopefully anybody can help me with this problem.
SQL-statement:
Function getDeleteRequestSQL(ByRef strRequestId As String) As String
Dim strSQL As String
strSQL = "DELETE FROM thmld2 WHERE right(hdmcode,8)='" & strRequestId & "'"
getDeleteRequestSQL = strSQL
End Function
And then the place where the error occurs.
GetConnection cnConn
strSQL = getDeleteRequestSQL(reqId)
10 cnConn.Execute strSQL, , adExecuteNoRecords
And finaly the trigger:
create trigger td_thmld2 on thmld2 for delete as
begin
declare
@numrows int,
@errno int,
@errmsg varchar(255)
select @numrows = @@rowcount
if @numrows = 0
return
select @numrows = (select count(*) from trigstat with (nolock) )
if @numrows > 0
return
save transaction trans_td_thmld2 <-- REASON FOR ERROR?
/* delete all children in "thmstat" */
delete thmstat
from thmstat t2, deleted t1
where t2.hdmcode = t1.hdmcode
/* delete all children in "thmldlk1" */
delete thmldlk1
from thmldlk1 t2, deleted t1
where t2.hdmlmldcode = t1.hdmcode
/* errors handling */
error:

Trying to create a trigger on a table that will delete any records in it that do not exist in another table.
Inserting into OrderRebateHistory Table.
if ordtype, ord_no, and line_seq_no do not exist in oelinhst then delete from OrderRebateHistory or do not insert.
Right now my code will insert the record. Then when another record gets inserted the previous record is deleted.
CREATE TRIGGER [DeletefromOrderRebateHistory] ON [dbo].[OrderRebateHistory]
for INSERT
AS
DELETE OrderRebateHistory
FROM OrderRebateHistory inner join oelinhst_sql on oelinhst_sql.ord_type = OrderRebateHistory.ord_type and
oelinhst_sql.ord_no = OrderRebateHistory.ord_no and oelinhst_sql.line_seq_no = OrderRebateHistory.line_seq_no
where oelinhst_sql.ord_type <>OrderRebateHistory.ord_type and oelinhst_sql.ord_no <> OrderRebateHistory.ord_no
and oelinhst_sql.line_seq_no <> OrderRebateHistory.line_seq_no

hello,I googled around some time but I found no solution for this issue(SS2000).I have a table tblB which has to be filled whenever in another tabletblA records are inserted, updated or deleted.So I created one trigger which works fine for inserts and updates andfills my tblB. tblB is filled with other fields which I get from aview vwC.The issue is about this view. When in tblA a record is deleted, thecorresponding record in vwC does not exist and I can't fill tblB. Itried around with INSTEAD OF -Trigger and got error message becausetblA has RI cascades so this is not possible. A temp table could bethe right way? Can you show me an example?thanks--candide_sh

On the database that I am maintaining we are having some data integrity issues between our Logon table and another sub table that stores the LogonId.
The best solution would be to put in a foreign key, but that is going to require a lot of work and a lot of code changes for the entire system. This is what we plan to do, but this is not a quick fix. We need something that can be implemented quickly.
The easiest and quickest fix is to check this sub table to see if the LogonId is in the sub table and the row is marked as Active or Working. If it is then we will abort the deletion and raise an error. Otherwise the delete should happen normally.
Is aborting the deletion as simple as :
<code>
Delete From deleted
Where LogonId = @myId
</code>
Or am I missing something?
Thanks for the help,
Tim

Hi,
I have two tables:
table A with key name, version
table B with key id and foreing key A.name,A.version.
The realtion A to B is 1:n
I use following trigger to keep data integrity (when record in A deleted, all records with corresponding foreing key should be deleted from table B):
CREATE TRIGGER trDelA ON A
FOR DELETE
AS
DECLARE @n int , @ver int
SELECT @n = name , @ver = version
FROM deleted
DELETE B
FROM B,A WHERE
@n=B.name AND
@ver=B.version
This trigger works fine, except the case that it doesn't fire when last record deleted from A.
why does it happens? how can I fix it?
Thank you
p.s. i'm using sql server 2000

I've got a ContactInfo table, that stores a variety of information about a contact (i.e. first/last name, address, phone, date of birth, status, etc.). I seem to be randomly loosing contacts though. Older backup's of my database still show a given contact, but the current one doesn't. It's happened a few times, and I can't seem to track what's causing it. (Nothing that I'm doing *should* be causing the contact to be deleted).
I'm looking to create a delete trigger for the table, so that any time a record gets delete, it will record what record got deleted (contactID, firstName, lastName), as well as what time it got deleted, and if possible, what function cause the delete (what function was accessing the table when the delete happened).
I've got some basic knowledge of SQL, and SQL statements, but my knowledge is limited... so any help on this would be greatly appreciated - or, if someone could point me to a website with good suggestions and examples, to help me create a trigger to monitor this stuff. I would be greatly indebted for any help that could be offered.
Here is kind of a shell for a delete trigger that I have been able to put together from some various examples I've found.
IF EXISTS (SELECT name FROM sysobjects
WHERE name = 'trDeleteContactInfo' AND type = 'TR')
DROP TRIGGER trDeleteContactInfo
GO
CREATE OR REPLACE TRIGGER trDeleteContactInfo
on ContactInfo
FOR DELETE
AS
EXEC master..xp_sendmail 'my@email.com',
'Contact has just been deleted from ContactInformation Table'

Have gone through BOL and Google, but can't find the answer... please helpwith a simple Q. I'm trying to create a simple cascade delete trigger in SQLServer 7 where deleting "parent" records in table X delete correspondingchild records in table Y.Table X=========X_IDSOME_VALTable Y=========Y_IDX_IDSOME_VALWhen there is no relationship between X.X_ID and Y.X_ID, the followingtrigger works fine:CREATE TRIGGER "temp" ON xFOR DELETEASdeletefrom ywhere x_id in (select x_id from deleted)However, when a relationship is created to enforce referential integrity,the trigger fails, with a "DELETE statement conflicted with COLUMN REFERENCEconstraint" error. I've seen examples where the trigger says (for example)"AFTER INSERT", where presumably the code is specifically run after theevent that triggers it -- is there a way of forcing the trigger to runbefore the delete from table X is executed? I've tried using "BEFOREDELETE", but no dice :-Thanks!--Aidan Whitehall <aidanwhitehall@fairbanks.co.uk>Macromedia ColdFusion DeveloperFairbanks Environmental Ltd +44 (0)1695 51775

The procedure deletes some record in tableT1.The table T1 has a trigger after delete.This is very importand for me, that the SP will be finished ASAP,that's why, I do not want, and I do not need to wait for a trigger.Does the SP will be finished, after the trigger is finished?Means, does the SP "waits" for a trigger?I think it is like that. Is it anyhow possible, to set the trigger (orthe procedure) that it want's be waiting for a result of triggerexecution?Thank You for kindly replyMateusz

I am trying to write a delete trigger that fires when the user deletes the only record for a given entity in the table. In this situation I have an entity PMA which can have one or many uses. I want the trigger to fire if the user tries to delete the last use record for that PMA_NUM from the PMA_USE table.
Here is my code:
if (SELECT Count(pma_use.pma_num) FROM dbo.PMA_USE
inner join dbo.deleted as D1 on dbo.PMA_USE.PMA_NUM= d1.PMA_NUM) = 0
BEGIN
RAISERROR ('Cannot delete only Use for PMA!', 16, 1)
ROLLBACK TRANSACTION
END
I seem to be getting inconsistent results when I create the trigger and when I try to test it re the deleted table
Sometimes when I run the trigger script in Management Studio Express, it has trouble with my using dbo.deleted and sometimes it doesn't
When I try to test the trigger by using MSE to view the table and delete the last use record for a PMA, I get an invalid object cannot find 'dbo.deleted' or cannot find 'deleted'
What am I doing wrong?

HelloI have a Trigger on a table. Here is the code ALTER TRIGGER [dbo].[OnOrderDelete]

AFTER DELETE,UPDATE
AS
BEGIN
SET NOCOUNT ON;
DECLARE @ids int;
SELECT @ids =( SELECT id from DELETED);
DELETE FROM files WHERE OrderId = @ids;
ENDActually the UPDATE event handler is not wanted here, but why when I leave him I have a following behaviour:When orders table is updated, the "SELECT @ids =( SELECT id from DELETED);
DELETE FROM files WHERE OrderId = @ids;" part is executed, and the program recognizes DELETED as UPDATED! (Like " SELECT @ids =( SELECT id from UPDATED) ") Is this right? And how can I part UPDATED and DELETED ?ThanksArtashes

hello:
This is a question about The MS SQL Server 7.0 table trigger for delete.
In a "delete" SQL statement , no matter how many rows are effected,
the table trigger for delete just only fire one time. I don't think
this is properly. Is this the MS SQL Sever behavior?
I've studied the MS SQL server books online, but I can't find any information like "for each row" in Oracle.
Could you please help me? Thanks a lot.

Greetings
I'm clear about the use of a DELETE trigger to "move" your deleted record to a second database as a sort of recycle bin.
But SS7 has the limitation, and it's mentioned in BOL, that it cannot reference your TEXT, NTEXT or IMAGE fields in the DELETED table. It says to join the original table with DELETED to get at those fields.
The only problem is the original table's record has been deleted! Even though the transaction has not yet been COMMITTED.
Here's my Trigger:
CREATE TRIGGER AuditTest ON Activity FOR DELETE AS
INSERT AuditDB.dbo.Activity
SELECT Activity.* FROM Activity INNER JOIN Deleted
ON Activity.ActivityID = Deleted.ActivityID
And for discussion, here's my Table:
ActivityID uniqueidentifier
OrgId uniqueidentifier
Title varchar(600
Active bit
Comments text
LastUpdate datetime
Any suggestions? Has anyone been able to implement a DELETE Audit
Trigger on a table with BLOBs?
Thanks,

I have a table where I want to prevent user from deleting or setting a flag on a field to "y" with a database trigger (sql 2000).

Hi,
Thanks for looking at this post. I currently have a trigger that fires when a row is inserted or deleted on a table. The idea behind the trigger is that when a row is inserted (representing a sub-category for images), the categories parent needs to have some work done on it. I currently have the trigger working just fine with single inserts and single deletes:
sql Code:

DELETE FROM smvcModImageManagerCategory WHERE (smvcModImageManagerCategory.id IN ('86','87','88','90','91'))
I get an error because the virtual 'Deleted' table has more than one record in it. So, what I really need is advice on how to turn the above trigger into something that will be able to handle multiple deletes.
Thank you.

I am having problems with a trigger that is designed to audit changes to a particular field in a table. If that field is updated, then the old record is inserted into an audit table.
This trigger never fails when I run test data against it from Query Analyzer. It works some of the time when the web application updates it, fails other times.
Typically, multiple records are updated at the same time. Any ideas?
Here is the Trigger:
create trigger t_u_product_rate_detail
on product_rate_detail
for insert, update, delete
as
/--Local variable
declare
@auditdate datetime,
@audituser sysname
--Set values so function isn't executed a bunch of times
select
@auditdate = getdate(),
@audituser = suser_sname()
if exists (select * from inserted)
begin
if exists (select * from deleted)
begin
insert into product_rate_detail_audit_log
select d.product_rate_detail_id,
d.product_rate_id,
d.day_of_week_id,
d.ad_size_id,
d.rate,
d.plan_vol,
d.plan_freq,
@auditdate, @audituser, 'U'
from deleted d
join inserted i on i.product_rate_detail_id = d.product_Rate_detail_id
where (d.rate <> 0 and d.rate is not null)
and i.rate <> d.rate -- this determines if the rate has changed.
end
end

I have a delete trigger on one table. When I delete a single row in this table that deleted record will be recorded to a history table.But sometimes my delete will delete more than one record. In this case also only one record is being recorded into the history table.How can I record all the deleted records into the history table when multiple records are deleted with one single delete statement?
