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
--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
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
I HAVE TWO TABLES IN THE DATABSE AND THE SECOND TALE SI FOR AUDITING. I WANT CREATE THE TRIGGER ON FIRST TABLE SO THAT I CAN PUT THE STATUS LIKE INSERT,UPDATE OR DELETE IN THE STATUS COLUMN IN SECOND TABLE. CAN SOMEBODY HELP IN WRITING THAT TRIGGER..? HOW CAN I DETERMINE WAETHER THE RECORD IS BEEN INSERTED OR UPDATED OR DELETED.
DO I HAVE TO WRITE A SEPERATE TRIGGER FOR EACH ACTIVITY..OR I CAN WRITE IT IN THE SINGLE TRIGGER..?
I have to create a trigger that will log who changed information on a table and when (NOT what they have changed).
My idea is to get the users name and see if it is in a table if not create it and get the associated ID, also get the ID of table that was accessed along with the ID of the type of task that was performed. Take this data and insert it into a table.
I have a question about trigger. I have a table called "Users", it has a ID (auto increment), UserName, FirstName...ect. The question is if one row is deleted, I want to put this row into "Users_Histroy" Table whose structure is the same as "Users" Table and then delete this row in "Users" Table.. How can I achieve this? I am pretty new about triggers. Thank you very much.
I have 3 tables...TableA, TableB, TableC TableA - Personal InformationPersonalInfoId (Primary) , First Name,Last NameTableB - Personal Information To Department IDReferenceID, FKPersonalInfoId, FKDepartmentIdTableC - DepartmentDepartmentId, DepartmentNameI am coding Asp.Net VB using VWD express with Sql Server Express. I know how to create a stored procedure to delete, insert and even update a record in TableA, TableB, TableC respectively.If I need to delete a record in TableC, which has a related record in TableB, I have read that I need to use a Trigger. I never have used a Trigger and it is new to me. Can someone point me a way on how to use one in this case of my deleting scenario. Pretty much, if a user clicks on a delete button, and deletes a record in my TableC, I dont want a FKDpartmentId in my TableB that doesnt exist anymore because it was deleted in TableC or prevent a user from deleting that record till the relationship in TableB is no longer valid. In the same vain, If I have a input form which ask the user to enter their First Name and Last Name and Department, i would like to add those records in TableA for First and Last Name, TableB for the Department. Once again, how do I create a Trigger that if I insert a record in Table A to also insert the information for Department in Table B, if its successful in my stored procedure. Hope that made sense.Thanks.
What statement do I use, as part of an insert trigger, to insert xml data from the xml database to a flat file database, to check if a record with a specific ID exists to delete first then insert the changed record, instead of adding the changes or an updated from the original xml database.
What I’m trying to do is take the xml formatted data out of one sql server database and insert the data only in that xml into a another sql database. So I can play with the data.
Problem is if the data in the xml is updated or changed for a specific record on the original xml database then the trigger inserts another copy into the created database (which I don’t want).
I have an c# windows service, which is running on the same machine where my mssql server is installed. This service must be informed for each insert/update/delete event on one specific table.
My idea was to create an CLR Trigger for this table which can communicate with this service via .NET remoting. But the problem is, that the system.runtime.remoting assembly is not integrated within the mssql clr enviroment => i can't use remoting.
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).
I want to be able to create a trigger that updates table 2 when a row is inserted into table 1. However I€™m not sure how to increment the ID in table 2 or to update only the row that has been inserted.
I want to be able to create a trigger so that when a row is inserted into table A by a specific user then the ID will appear in table B. Is it possible to find out the login id of the user inserting a row?
I believe the trigger should look something like this:
create trigger test_trigger on a for insert as insert into b(ID)
This problem is being seen on SQL 2005 SP2 + cumulative update 4
I am currently successfully using the output clause of an insert statement to return the identity values for inserted rows into a table variable
I now need to add an "instead of insert" trigger to the table that is the subject of the insert.
As soon as I add the "instead of insert" trigger, the output clause on the insert statement does not return any data - although the insert completes successfully. As a result I am not able to obtain the identities of the inserted rows
Note that @@identity would return the correct value in the test repro below - but this is not a viable option as the table in question will be merge replicated and @@identity will return the identity value of a replication metadata table rather than the identity of the row inserted into my_table
Note also that in the test repro, the "instead of insert" trigger actually does nothing apart from the default insert, but the real world trigger has additional code.
To run the repro below - select each of the sections below in turn and execute them 1) Create the table 2) Create the trigger 3) Do the insert - note that table variable contains a row with column value zero - it should contain the @@identity value 4) Drop the trigger 5) Re-run the insert from 3) - note that table variable is now correctly populated with the @@identity value in the row
I need the behaviour to be correct when the trigger is present
GO /************************************************ 2) - Create the trigger ************************************************/ CREATE TRIGGER [dbo].[trig_my_table__instead_insert] ON [dbo].[my_table] INSTEAD OF INSERT AS BEGIN
INSERT INTO my_table ( forename, surname) SELECT forename, surname FROM inserted
END
/************************************************ 3) - Do the insert ************************************************/
INSERT INTO my_table ( forename , surname ) OUTPUT inserted.my_table_id INTO @my_insert VALUES( @forename , @surname )
select @@identity -- expect this value in @my_insert table select * from @my_insert -- OK value without trigger - zero with trigger
/************************************************ 4) - Drop the trigger ************************************************/
drop trigger [dbo].[trig_my_table__instead_insert] go
/************************************************ 5) - Re-run insert from 3) ************************************************/ -- @my_insert now contains row expected with identity of inserted row -- i.e. OK
Hello, For SQL Server 6.5. I need help if there is a way to fire a delete trigger when accidentenlty somebody deletes a record from say table AAA then this record should be inserted in another dump table say Table BBBDump with table schema as table AAA plus some other columns like DB_NAME,Time when recorded deleted from table AAA, user ID .
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.
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
i have created a view from two tables in my database (ProjectedOutputs, and Output)
since I am using the view in vb to fill a grid, i am trying to set up a INSTEAD OF DELETE trigger to delete any records in ProjectedOutputs that may be deleted from my grid. 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
CREATE TRIGGER Test ON V_ProjectOutputs INSTEAD OF DELETE AS
DELETE PROJECTEDOUTPUTS FROM PROJECTEDOUTPUTS JOIN deleted ON PROJECTEDOUTPUTS.ProjectedOutputID = deleted.ProjectedOutputID
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.

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
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

Hi! I am deleting some records from the database and at the same time inserting them into a new table. I am doing all this with sql querries. How can that be done with triggers. Basically on the delete, i'd like to insert the affected records. Thanks! James
I have the following delete trigger but it doesn't work.
ALTER TRIGGER Users_DeleteUsers ON dbo.Users FOR DELETE AS DELETE FROM InstantForum_Members WHERE MemberID IN (SELECT ForumMemberId from Deleted) DELETE FROM InstantKB_Users WHERE UserID IN (SELECT KBMemberId from Deleted)
But when I delete a user from Users table, I get an error in this trigger saying no commit or rollback given in trigger.
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>
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?
I have 4 colums in a table Project, Sections,Tasks,Subtasks Each subtask will haven a row.
I need to write a trigger when I delete a task it needs to delete all the subtasks relating to it. When I delete a section it needs to delete all the tasks and subasks relating to it. similarly for project. This trigger for task-subtask works. CREATE TRIGGER "[Deletetasktrigger]" ON [Tbl] FOR DELETE AS SET NOCOUNT ON /* * CASCADE DELETES TO '[Tbl B]' */ DELETE [tbl] FROM deleted, [Tbl] WHERE deleted.[task] = [Tbl].[task] THis works fine. But when I do it for sections I get this error.
i have the following trigger ...anytime the user table is inserted or updated it writes to the UserProfileLog...which is what I want...but I also want it to write into UserProfileLog when the record from Users is deleted
here is my trigger...what am I doing wrong???
CREATE trigger trg_UserProfiles on dbo.Users for insert, update, delete as insert into UserProfileLog(UserID, UserAccess, UserFirstName, UserLastName, UserName, UserEmail, UserStreet, UserCity, UserState, UserZip, UserHomePhone, UserWorkPhone, UserCellPhone, UserPager, EditedBy) select UserID, UserAccess, UserFirstName, UserLastName, UserName, UserEmail, UserStreet, UserCity, UserState, UserZip, UserHomePhone, UserWorkPhone, UserCellPhone, UserPager, EditedBy from inserted
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' GO
