Drop Trigger With A Variable Trigger Name
Sep 20, 2007
Hi all in .net I've created an application that allows creation of triggers, i also want to allow the deletion of triggers.
The trigger name is kept in a table, and apon deleting the record i want to use the field name to delete the trigger
I have the following Trigger
the error is at
DROP TRIGGER @DeleteTrigger
I'm guessing it dosen't like the trigger name being a variable instead of a static name
how do i get around this?
thanks in advance

Created an assembly based on this article...
http://sqljunkies.com/Article/4CD01686-5178-490C-A90A-5AEEF5E35915.scuk
Now I want to make changes and redeploy the assembly but when I try to drop I get this.
IF EXISTS (SELECT * FROM sys.assemblies asms WHERE asms.name = N'AuditCommon')
DROP ASSEMBLY [AuditCommon]
Msg 6590, Level 16, State 1, Line 3
DROP ASSEMBLY failed because 'AuditCommon' is referenced by object 'clr_trigger'.
Any ideas?

I created a trigger that will throw a message whenever a new record is inserted in the table. Now I want to remove this trigger. I am not able to remove.
CREATE TRIGGER prod_culture_trig ON Production.Culture
AFTER INSERT
AS
SELECT 'New culture entry added';
I get the following error message:
Msg 2714, Level 16, State 2, Procedure prod_oulture_trig, Line 4
There is already an object named 'prod_oulture_trig' in the database.
This error confirms that we have the trigger already existing. Now I run the code
DROP TRIGGER prod_oulture_trig;
I get the following error message -
Msg 3701, Level 11, State 5, Line 1
Cannot drop the trigger 'prod_culture_trig', because it does not exist or you do not have permission.
What permission do I require? This is a test database on my computer with me as the administrator.
How to remove this trigger?

I have a DDL Trigger that writes a record into a table when any DDL event happens.
It works great except when I try dropping any object. I get an error at that point and the object is not dropped. The trigger and error are listed below.

I created a trigger on a replicated table in a publishing database on SQL Server 2000. When I attempt to ALTER TABLE ... DISABLE TRIGGER ..., I get a message that I cannot alter the table since it is part of a publication. Does anyone know if I would be able to issue a DROP TRIGGER or ALTER TRIGGER on a replicated table?
Thanks,
Gerald

I am writing an audit trail trigger that needs to query columns, but the specific column names are not known until the trigger runs and determines what columns have changed. Once I know the changed column(s) I fetch the column name. No sweat.
The problem is using a variable in place of a column name I can not get the data to return, only the column name.
-- Here is how I get the column name. It works great, @CName
-- reflects the column name as I use it elsewhere fine.
Select @CName = col_name(OBJECT_ID('TABContract'), @CNum)
-- This simple syntax usually works, it does not using a
-- variable as the column name. @Prev is populated with
-- @CName literally. I have tried various and asundry ()'s and []'s
Select @Prev = @CName From Deleted
-- Here I have hard coded the Column name and ran a test modifying that column "Comment" and it works! @Prev is populated with the columns data not the Column name.
Select @Prev = Comment From Deleted
-- Tried these syntaxes, no luck
Select @Prev = (Select @CName From Deleted)
Select @Prev = (Select col_name(OBJECT_ID('TABContract'), @CNum) From Deleted)
Any help appreciated,

Hello, I have a very simple trigger that only copies the data from one table to a historial table, when a row is deleted. It works fine, but now I need to change it becouse I am inserting a new column to the table, which type is ntext, and when I try to declare a ntext variable (inside the trigger), it does not allow me. Does anyone know how to go round this? Here is the code of the trigger (maybe it is not efficient, as I am a newbie in this :D, please tell if so as well)
CREATE TRIGGER OnDelete ON dbo.Tracker
FOR DELETE
AS
declare @IDregistro as integer;
declare @IDTIT as integer;
declare @negocio as nvarchar(50);
declare @fechaOr as datetime;
declare @asuntoOr as nvarchar(50);
declare @estadoOr as nvarchar(50);
declare @descripcionOr as nvarchar(255);
declare @usuarioOr as nvarchar(50);
declare @contactoOr as nvarchar(50);
declare @companiaOr as nvarchar(40);
--declare @desc as ntext; --DOES NOT WORK!!
declare @fechaSus as datetime
select @fechaSus = getdate()
select @IDregistro = IDregistro from deleted;
select @IDTIT = IDTitular from deleted;
select @negocio = negocio from deleted;
select @fechaOr = fecha from deleted;
select @asuntoOr = asunto from deleted;
select @estadoOr =estado from deleted;
select @descripcionOr = descripcion from deleted;
select @usuarioOr = usuario from deleted;
select @contactoOr = contacto from deleted;
select @companiaOr = compania from deleted;
insert into Historico (IDregistro, IDtitular, Negocio, FechaSuceso,TipoSuceso, FechaOriginal, AsuntoOriginal, EstadoOriginal, DescripcionOriginal, UsuarioOriginal, ContactoOriginal, CompaniaOriginal) Values (@IDregistro, @IDTIT, @negocio, @fechaSus, 'DELETE', @fechaOr, @asuntoOr, @estadoOr, @descripcionOr, @usuarioOr, @contactoOr, @companiaOr)

I need to pass a application userid on every call to my database for triggers on the db to use.
I am connecting to my database using integrated security from my application, all on one windows domain account. However I need to get an application user id over on the connection for triggers to use to stamp in changelogs.
Currently everytime we open a connection we create a #table with the user id in it, but that is expensive, especially in our new SOA where connections are frequently created and dropped on requests.
Is there any way I can get a connection level variable over to the database server so triggers could read it?
Any help is greatly appreciated.

Hey,
I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with:
WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc.
Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below)
Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending
Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government]
Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc.
Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies.
Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
Thanks.

This Audit Trigger is Generic (i.e. non-"Table Specific") attach it to any tabel and it should work. Be sure and create the 'Audit' table first though.
The following code write audit entries to a Table called
'Audit'

When a row gets modified and it invokes a trigger, we would like to beable to update the row that was modified inside the trigger. This is(basically) how we are doing it now:CREATE TRIGGER trTBL ON TBLFOR UPDATE, INSERT, DELETEasupdate TBLset fld = 'value'from inserted, TBLwhere inserted.id= TBL.id....This work fine but it seems like it could be optimized. Clearly we arehaving to scan the entire table again to update the row. But shouldn'tthe trigger already know which row invoked it. Do we have to scan thetable again for this row or is their some syntax that allows us toupdate the row that invoked the trigger. If not, why. It seems likethis would be a fairly common task. Thanks.

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,

Hi,
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
where i.req_guid = d.req_guid
and i.req_fname <> d.req_fname
Thanks,

declare @radius_default varchar(40)
select @radius_default = (select sobj.name from sysobjects sobj

Hi,
Does anybody know how could I define a for each row trigger in sql Server 2005?
What I need to do is before inserting in the table look through the rows to check wheter that value overlaps with the others.
"Overlap" means that this value cannot be betweent the values fo two different columns, that is why I need to go through all the table.
In case that was not possible, I propose the following, load the table in a dataset and check the constraint with a for loop despite of the performance could be decreased.
Any suggestion?.
Thanks in advance.
Cheers.
