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 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?

I have three tables: BulkMemberHeader - which has a cascade delete on BulkMemberDetail of any related records BulkMemberDetail €“ which has a DELETE trigger which gets the member ID from deleted and deletes the member record from the member table Member
This issue: > When I delete a record from BulkMemberDetail the trigger fires and deletes the record from the Member table as it should > If I delete a record from the BulkMemberHeader, all corresponding records in BulkMemberDetail are deleted, but the trigger to delete the record in the Member table does not seem to fire
Is it a limitation on SQLServer 2000 that does not allow triggers to fire in a scenario like this?
I am using Sql Server 2000. I have a customer table with fields - CustId, Name, Address, City, StdCode, Phone. I used to insert entries in this table from an excel file. One excel file will contain thousands of customer. In this table combination of StdCode and Phone should not be repeated. If I do it in my VB.Net coding.then application gets drastically slow. So I want to write a procedure or trigger for this. Here what I will do, I will send all records into database then this trigger or procedure will check for any existing entry of combination of StdCode and phone. If entry exists then this will delete new entry or will not allow this new entry. Is this possible to do using Trigger or stored procedure?
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 have a SQL script to insert data into a table as below:
INSERT into [SRV1INS2].BB.dbo.Agents2 select * from [SRV2INS14].DD.dbo.Agents
I just want to set a Trigger on Agents2 Table, which could delete all rows in the table , before carry out any Insert operation using above statement.I had below Table Trigger on [SRV1INS2].BB.dbo.Agents2 Table as below: But it did not perform what I intend to do.
USE [BB] GO /****** Object: Trigger   Script Date: 24/07/2015 3:41:38 PM ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON
there are two tables involve in replication let say table1 and replicated table is also rep.table1.
we are not deleting records physically in table1 so only a bit in table1 has true when u want to delete a record but the strange thing is that replication agaent report that this is hard delete operation on table1 so download and report hard delete operation and delete the record in replicated table which is very crucial.
plz let me know where am i wrong and how i put it into right way.
there is no triggers on published tables and noother trigger is created on published table.
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
Insert into dbo.AUDIT (audit_req, audit_new_value, audit_field, audit_user)
select i.req_guid, i.req_fname, 'req_fname', IsNull(i.req_last_update_user,@default_user) as username from inserted i, deleted d
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.

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

Background: Am working on completing an ORM that can not only handles CRUD actions -- but that can also updates the structure of a table transparently when the class defs change. Reason for this is that I can't get the SQL scripts that would work for updating a software on SqlServer to be portable to other DBMS systems. Doing it by code, rather than SQL batch has a chance of making cross-platform, updateable, software...
Anyway, because it needs to be cross-DBMS capable, the constraints are that the system used must work for the lowest common denominator....ie, a 'recipe' of steps that will work on all DBMS's.
The Problem: There might be simpler ways to do this with SqlServer (all ears :-) - just in case I can't make it cross platform right now) but, with simplistic DBMS's (SqlLite, etc) there is no way to ALTER table once formed: one has to COPY the Table to a new TMP name, adding a Column in the process, then delete the original, then rename the TMP to the original name.
This appears possible in SqlServer too --...as long as there are no CASCADE operations. Truncate table doesn't seem to be the solution, nor drop, as they all seem to trigger a Cascade delete in the Foreign Table.
So -- please correct me if I am wrong here -- it appears that the operations would be along the lines of: a) Remove the Foreign Key references b) Copy the table structure, and make a new temp table, adding the column c) Copy the data over d) Add the FK relations, that used to be in the first table, to the new table e) Delete the original f) Done?
The questions are: a) How does one alter a table to REMOVE the Foreign Key References part, if it has no 'name'. b) Anyone know of a good clean way to get, and save these constraints to reapply them to the new table. Hopefully with some cross platform ADO.NET solution? GetSchema etc appears to me to be very dbms dependant? c) ANY and all tips on things I might run into later that I have not mentioned, are also greatly appreciated.
I'm trying to clean up a database design and I'm in a situation to where two tables need a FK but since it didn't exist before there are orphaned records.
Tables are:
Brokers and it's PK is BID
The 2nd table is Broker_Rates which also has a BID table.
I'm trying to figure out a t-sql statement that will parse through all the recrods in the Broker_Rates table and delete the record if there isn't a match for the BID record in the brokers table.
I know this isn't correct syntax but should hopefully clear up what I'm asking
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 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???

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
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
Hello to all,I have a small question.I call the SP outer the DB. 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

Can anyone help me with setting up a simple Delete Trigger, so that whenever a contact gets deleted from the table, it will log as munch information as possible about what just happened (maybe what functions just got ran, what info just changed, whatever...); so that way I can try and get some more information on the problem, and try and diagnose what is causing the deletions.

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'
