Hi,
I have a Insert / Update Trigger on Table called TBL_A. Inside the trigger I am updating the same table TBL_A.
Will this cause recursion of the trigger? And will it keep on firing again and again?
Thanks in advance ...jfk

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)
select i.id
from inserted i
where
--specific USER
If the id1 will change in table1 it should also change the corresponding id1 field in table2 it does not do anything.
CREATE TRIGGER [dbo].[IDCHANGE]
ON [dbo].[table1]
AFTER UPDATE
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
[Code] .....
I got error while updating a table ,duplicate entries and trigger got fired ..so how to debug the trigger to know duplicate record.
View 1 Replies View RelatedI am very new to SQL Server 2005. I have created a package to load data from a flat delimited file to a database table. The initial load has worked. However, in the future, I will have flat files used to update the table. Some of the records will need to be inserted and some will need to update existing rows. I am trying to do this from SSIS. However, I am very lost as to how to do this.
Any suggestions?
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,

Hi All,I'm a relatively newbie to SQL Server 2000, having come from a MySQLbackground.I'm creating my first Trigger statement on a table, and I'd like toknow how I go about performing an update on the row that was changedwhen the trigger was fired.To explain, I have 2 columns, one which contains a member number, theother which contains a flag that is supposed to indicate whether ornot the member number in the row has changed since the last time thetable was processed for updates.So, whenever the value in the member number field [memnum] is updated,I want to set the flag [igproc] to true.The best I've been able to do is:CREATE TRIGGER [updateignoreprocflag] ON [dbo].[dd_testtable]FOR UPDATEASdeclare @key as intIF UPDATE (memnum)select @key = recid from insertedUPDATE dd_testtable set igproc=1 where recid=@keyThis seems to work, but I'd like to know if there's a better way ofretrieving the recid value of the changed row to pass to the UPDATEstatement? Also, I read somewhere in passing that using SELECTstatements and variable assignments within triggers can cause problemswhen called from other applications; in this case it will either be aweb site using ASP.or an application developed in FOXPRO. I can't findwhere I read this originally, so it's entirely possible I imagined itor misunderstood it, but I'd very much appreciate it if someone couldconfirm whether or not this is the case?Many, many thanks in advance!Much warmth,Murray

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.
Are there any limitations or gotchas to updating the same table whichfired a trigger from within the trigger?Some example code below. Hmmm....

Hello friends,
I am new to the SQL Server 2005 development.
From last 1 week or so, i have been facing very strange problem with my sql server 2005s database
which is configured and set on the hosting web server. Right now for managing my sql server 2005 database,
i am using an web based Control Panel developed by my hosting company.
Problem i am facing is that, whenever i try to modify (i.e. add new columns) tables in the database,
it gives me error saying that,
"There is already an object named 'PK_xxx_Temp' in the database. Could not create constraint. See previous errors.
Source: .Net SqlClient Data Provider".
where xxx is the table name.
I have done quite a bit research on the problem and have also searched on the net for solution but still
the problem persist.
Thanks in advance. Any help will be appreciated.

I am trying to update a table in one database with data from a temporary table which i created in the tempdb.

UPDATE [dbname].dbo.table
SET [dbname].dbo.table.field1 = [tempdb].dbo.#temp_table.tempfield1
WHERE ( [dbname].dbo.table.field2= [tempdb].dbo.#temp_table.tempfield2
AND [dbname].dbo.table.field3= [tempdb].dbo.#temp_table.tempfield3

I want to write trigger code to update values in table1 to table2.
ALTER, CREATE, DROP cannot be used in a trigger, I guess.
Tabel1

1, B, 16 , 06/08/04 Y
1, C, 12 , 07/08/04 Y
1, D, 13 , 10/08/04 Y
2, E, 10 , 15/08/04 Y
2, F, 11 , 16/08/04 Y

2, G, 15 , 17/08/04 Y
3, H, 13 , 19/08/04 Y
3, I, 15 , 02/08/04 N
Table2 after update
ID, Name1, Asset1, Date1, Name2, Asset2, Date2, Name3, Asset3, Date3, Name4, Asset4, Date4
---------------------------------
1,B,16,06/08/04,D,13,10/08/04,C,12,07/08/04,A,10,01/08/04
2,F,11,16/08/04,E,10,15/08/04,blank,blank, blank..
3,H,13,19/08/04,blank, blank...
As you can see, code must select only active('Y') names in table1 arrange in descending order of asset for each ID and updates(or insert into?)table2.
Please help me with code

I need to update the data in one table with dat from another.
i have a table called tblclients and a column called intethnicity. I also have a table called tblethnicity. The column in the table intethnicity should be the primary key integer for the corresponding ethnicity. So since most of the clients are caucasian, and the id for caucasian is 4, the intethnicity column should be 4.
Here is the problem:
I have a table of 1300 hundred records and the column intethnicity now has the actual ethnicity in it instead of the corresponding id for the ethnicity. I need a way to update all the records so that the intethnicity column has the id for the corresponding ethnicity, not the actual ethnicity itself.
I know I can go uodate tblcients set intethnicityid =4 where intethnity ='white', but that would take too long.
I need a way to update the column based on the id from the table ethnicity.
Any help would be appreciated.
Hi
How do I update my table, that is part of my .sdf database stored on disk?
Can I use databinding with this? Or do i have to use SQL INSERT command?
I€™m in the process of rewriting several AbInitio graphs into SSIS and ran into something that I€™m not sure how to handle in SSIS. In AbInitio when you use their update component you can redirect records that aren€™t used in the update command. How would I do the same thing in SSIS?
Right now I€™m using the OLE DB Command component but don€™t see how I can take the records that didn€™t update anything and capture them in a flow out. Any help would be greatly appreciated.
