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)
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
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.
Are there any limitations or gotchas to updating the same table whichfired a trigger from within the trigger?Some example code below. Hmmm.... This example seems to be workingfine so it must be something with my specific schema/code. We'reworking on running a SQL trace but if anybody has any input, fireaway.Thanks!create table x(Id int,Account varchar(25),Info int)GOinsert into x values ( 1, 'Smith', 15);insert into x values ( 2, 'SmithX', 25);/* Update trigger tu_x for table x */create trigger tu_xon xfor updateasbegindeclare @TriggerRowCount intset @TriggerRowCount = @@ROWCOUNTif ( @TriggerRowCount = 0 )returnif ( @TriggerRowCount > 1 )beginraiserror( 'tu_x: @@ROWCOUNT[%d] Trigger does not handle @@ROWCOUNT[color=blue]> 1 !', 17, 127, @TriggerRowCount) with seterror, nowait[/color]returnendupdate xsetAccount = left( i.Account, 24) + 'X',Info = i.Infofrom deleted, inserted iwhere x.Account = left( deleted.Account, 24) + 'X'endupdate x set Account = 'Blair', Info = 999 where Account = 'Smith'
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' with columns 'ActionType' //varchar 'TableName' //varchar 'PK' //varchar 'FieldName' //varchar 'OldValue' //varchar 'NewValue' //varchar 'ChangeDateTime' //datetime 'ChangeBy' //varchar

The trick was getting the Table Name and the Primary Key Columns. I hope this code is found useful.
we have various user defined fields, so when the user insert new value to this field , i want new records (other user field to get populated) be inserted relevant to the inserted value FROM another table (lookup)

I currently have 2 tables as follows:CREATE TABLE [CRPDTA].[F55MRKT119](mhan8 int,mhac02 varchar(5),mhmot varchar(5),mhupmj int)GOCREATE TABLE [CRPDTA].[F55MRKT11](mdan8 int,mdac02 varchar(5),mdmot varchar(5),mdmail int,mdmag int,mdupmj int)What I would like to do is place a trigger on F55MRKT119 which willinsert records to the F55MRKT11 if they do not exist in that tablebased on the [mdan8] field. If the record does exist I would likeUpdate the corresponding record and increment either the [MDMAIL] orthe [MDMAG] based on the inserted [MHMOT]. What I have so far is asfollows:TRIGGER #1:CREATE TRIGGER trgIns_Summary ON [CRPDTA].[F55MRKT119]FOR INSERTASBEGININSERT INTO CRPDTA.F55MRKT11select INS.MHAN8, INS.MHAC02, INS.MHMOT,case when INS.MHMOT='MAG' then 0 ELSE 1 end,case when INS.MHMOT='MAG' then 1 ELSE 0 end,'0' from INSERTED INSWHERE ins.mhan8 not in(select mdan8 from crpdta.f55MRKT11)ENDTRIGGER #2:CREATE TRIGGER trgUpd_Summary ON [CRPDTA].[F55MRKT119]FOR UpdateASBEGINUPDATE CRPDTA.F55MRKT11SET MDMAIL= case when INS.MHMOT='MAG' then 0+MDMAILwhen INS.MHMOT<>'MAG' then 1+MDMAIL end,MDMAG= case when INS.MHMOT='MAG' then 1+MDMAGwhen INS.MHMOT<>'MAG' then 0+MDMAG endfrom INSERTED INS JOIN CRPDTA.F55MRKT11on(ins.mhan8=mdan8)ENDFor instance if I do the following insert:INSERT INTO CRPDTA.F55MRKT119VALUES('212131','VK4','AL4','0')thenINSERT INTO CRPDTA.F55MRKT119VALUES('212131','VK4','MAG','0')This is what I expect in both tables:[CRPDTA.F55MRKT119] (2 Records)MHAN8 MHAC02 MHMOT MHUPMJ------ ------ ----- ------212131 VK4 AL4 0212131 VK4 MAG 0[CRPDTA.F55MRKT11] (1 Record)MDAN8 MDAC02 MDMOT MDMAIL MDMAG MDUPMJ----- ------ ----- ------ ----- ------212131 VK4 AL4 1 1 0The insert part works fine in that it iserts in both tables with thecorrect values. However it seems as if the Update protion is failingfor some reason. WHat I have tried so far is setting the trigger orderfor the update to run first and vice-versa, but still no luck. Anyhelp would be appreciated.
Hi,Does anyone know of a simple way to do this? I want to create aninsert trigger for a table and if the record already exists based onsome criteria, I want to update the table with the values that arepassed in via the insert trigger without having to use all the 'set'statements for each field (so if we add fields in the future I won'thave to update the trigger). In other words, I want the trigger codeto look something like this:if exists (select * from TableA where Fld1 = inserted.Fld1) then//don't do insert, do an update instead (would i want to rollback here?and will I have access to the 'inserted' table still?)Update TableASet TableA.<all the fields> = Inserted.<all the fields>where Fld1 = inserted.Fld1end ifAny help or ideas would be appreciated.Thanks,Teresa
hello everyone , i have a table named "Employee" with EmpID as PK. i want to insert EmpID one by one in another table named "AssignedComplaints" so if i have all the EmpID inserted in "AssignedComplaints" table then on next insert operation , the first EmpID will be inserted and then second on so on. like i gave u a sample i have three EmpIDs in "Employee" table named M1,M2,M3 first M1 is inserted secondly M2 and lastly M3. now i have all EmpID in "AssignedCompalints" table. now if i do want to insert again then the whole process will repeat , first M1 will be inserted secondly M2 and so on. i need the query i have created a trigger and will use this query in that trigger. thanks

Does anyone have a stored procedure for sending an email (using SQLMail) when a new record is added to a database table?
I have SQLMail all setup, I just need a good example of a stored procedure or trigger that will sending an email with the details for a new record entry into a table.
I have 2 tables (Dept and Emp) The columns in table Dept are Deptno and Deptname. Deptno is bigint and it is primary key. In Emp table, columns are Empno(PK) ,EmpName and Deptno(foreign key referring to Dept)
To Insert or Update record in Emp through application, value of Deptno is coming as 0(Zero). I want the value of Deptno to be inserted or updated as null if the value is Zero (0). How to do this in sql server 2005 by using trigger on table Emp
I'm trying to update (increment) Company.SumtotalLogons from CompanyUsers.NumberOfLogons where CompanyUsers.CompanyID = Company.CompanyID
I'd like to either write a formula (if it is even possible to fire a formula from one table update/insert to increment a field in another table), or a stored procedure that triggers an auto update/append into Company.SumTotalLogons
I know this is possible in access, so i'm wondering how to go about it in ms-sql?
Hello,i have a table and if a record is inserted i will test a numeric valuein this table. If the this value is greather as 1 million, than anstatus column should be changed from 'A' to 'B'.Yes and sorry, this is a newbie question.On Oracle this work simple:create trigger myTrigger on tableXasbeginif :old.x 100000 then:new.y:='B'end if;end;ThanksMaik
So, I've written an Instead of Trigger to update a foreign key field based on information in another field of the same record.
To add some error handling to the process I updated the Trigger to insert any records that don't have legitimate foreign keys into a second table.
This process works great when I test it by just adding a record using the table view in the SQL Management Studio or through a query run in the query browser.
However, when a record is added via an ODBC connection I get foreign key constraint errors and records are not added to the second table. If the foreign key is legit the record is added and the part of trigger that updates that keyed field executes just fine.
Is anyone aware of this issue? Is there a way around it?
I found the following MSKB article but I'm not sure if it applies to my situation: http://support.microsoft.com/kb/304096
Here's my current code, if that track the problem in anyway:
Code:
ALTER TRIGGER UpdateTicketID ON Email Instead of INSERT AS IF ((Select charindex('{', [subject]) FROM Inserted) = 0) BEGIN INSERT INTO BadEmail ([Subject], Sender, Body, EntryID, LastModificationTime, AttachmentLInk, SendTo, Cc, ContactID) Select [Subject], Sender, Body, EntryID, LastModificationTime, AttachmentLink, SendTo, Cc, ContactID From Inserted END ELSE IF ((Select substring([subject], charindex('{', [subject])+1, (charindex('}', [subject]) - charindex('{', [subject]))-1) From Inserted) NOT In (Select TicketID From Ticket)) BEGIN INSERT INTO BadEmail ([Subject], Sender, Body, EntryID, LastModificationTime, AttachmentLInk, SendTo, Cc, ContactID) Select [Subject], Sender, Body, EntryID, LastModificationTime, AttachmentLink, SendTo, Cc, ContactID From Inserted END ELSE BEGIN INSERT INTO Email ([Subject], Sender, Body, ticketID, EntryID, LastModificationTime, AttachmentLink, SendTo, Cc, ContactID) Select [Subject] , Sender , Body , substring([subject], charindex('{', [subject])+1, (charindex('}', [subject]) - charindex('{', [subject]))-1) , EntryID , LastModificationTime , AttachmentLink , SendTo , Cc , ContactID From Inserted END
I have a master table with after insert trigger on it.. When record is inserted into master table, the trigger fires and is captured in the backoffice table. In case the trigger fails, my record is neither in the master table nor in the back office table..
Is there anyway to capture the record either in the master table or in a separate table.
I have a problem described as follows: I have a table with one instead of insert trigger:
create table TMessage (ID int identity(1,1), dscp varchar(50)) GO Alter trigger tr_tmessage on tmessage instead of insert as --Set NoCount On insert into tmessage
[code]....
When I execute P1 it returns 0 for Id field of @T1.
How can I get the Identity in this case?
PS: I can not use Ident_Current or @@identity as the table insertion hit is very high and can be done concurrently.Also there are some more insertion into different tables in the trigger code, so can not use @@identity either.
I am developing an application in vb.net 2005 using SQL Server 2000. In this I have two tables SessionMaster and SessionChild. Fields of session master - SessionMastId, Start_Date, End_Date, Session_Type, Fields of session child - SessionChildId, SessionMastId, UserName, Comment. SessionMastId and SessionChildId are primary keys of respective tables and also they are auto increment fields. Please how to write trigger to insert record into both tables at a time.
I have a row that is being used log track plays on our website.
Here's the table:
CREATE TABLE [dbo].[Music_BandTrackPlays]( [ListenDate] [datetime] NOT NULL DEFAULT (getdate()), [TrackId] [int] NOT NULL, [IPAddress] [varchar](20) ) ON [PRIMARY]
There's a CLUSTERED INDEX on ListenDate ASC and a NON CLUSTERED INDEX on the TrackId.
I have a TRIGGER on the Music_BandTrackPlays table that looks like the following:
CREATE TRIGGER [trig_Increment_Music_BandTrackPlays_PlayCount] ON [dbo].[Music_BandTrackPlays] AFTER INSERT AS UPDATE Music_BandTracks SET Music_BandTracks.PlayCount = Music_BandTracks.PlayCount + TP.PlayCount FROM (SELECT TrackId, COUNT(*) AS PlayCount FROM inserted GROUP BY TrackId) AS TP WHERE Music_BandTracks.TrackId = TP.TrackId
When a simple INSERT statement is done on the Music_BandTrackPlays table, it can take quite a long time. When I remove the TRIGGER the INSERTs are immediate. The Execution plan for the TRIGGER shows that a 'Inserted Scan' is taking up most of the resources.
How exactly is the pseudo 'inserted' table formed?
For now, I think the easiest thing to do is update my logging page so it performs 2 queries. One to UPDATE the Music_BandTracks table and increment the counter, and perform the INSERT into the Music_BandTrackPlays table seperately.
I'm ok with that solution but I would really like to understand why the TRIGGER is taking so long. The 'inserted' pseudo table will be 1 row 99% of the time. Does SQL Server perform a table scan on all 20 million rows in order to determine what's new and put it in the inserted pseudo table?
I have two different SQL 2008 servers, I don't have permission to create a linked server in any of them. i created a trigger on server1.table1 to insert the same record to the remote server server2.table1 using OPENROWSET
i created a stored procedure to insert this record, and i have no issue when i execute the stored procedure. it insert the recored into the remote server.
The problem is when i call the stored procedure from trigger, i get an error message.
Stored Procedure: USE [DB1] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON
[Code] ....
When i try to insert a new description value in the table i got the following error message:

I do not insert/update/delete on the view directly.
For every insert/update in table A /B the values should get insert/update in the view respectively. This insert/update on view should invoke the trigger.

Trigger is working only if any operation is done directly on the view.

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
