I have written an Insert Trigger to examine newly inserted records and set some values. However, each time a record is inserted, all records are checked. How can I make the trigger work only on newly inserted records?
I'm working on inserting data into a table in a database. The table has two separate triggers, one for insert and one for update (I don't like it this way, but that's how it's been for years). When there is a normal insert, done via a program, it looks like the triggers work fine. When I run an insert manually via a script, the first insert trigger will run, but the update trigger will fail. I narrowed down the issue to a root cause.
This root issue is due to both triggers using the same temporary table name. When the second trigger runs, there's an error stating that a few columns don't exist. I went to my test server and test db and changed the update trigger so that the temporary table is different than the insert trigger temporary table, the triggers work fine. The weird thing is that if the temporary table already exists, when the second trigger tries to create the temporary table, I would expect it to fail and say that it already exists.I'm probably just going to update the trigger tonight and change the temporary table name.
Hello, what i want is simple. This is a simple forum, it has several topics (that the users can create), when a user create a topic, its stored in forum_topics. The user can then view the topic and post a response that is store in forum_answer, the user can also add this to his favorite list, forum_favorites is simple, contains a TopicID that refers to the topic, a username of the user that has the topic on his favorite list and a auto increment id to be able to delete specified topic favorites. Now my question is: when a user posts a answer to Topic X, i want a predefined message to be sent to post_inbox for all the users that has Topic X in their favorite list. How can i get MS SQL 2005 to get all the users from Topic X and then loop thru them and insert a new post into post_inbox?
I've been reading the docs and playing around, but I'm still notgetting the difference. For instance,create table a(i int check(i>0))create table a_src(i int)gocreate unique index ai on a(i) with IGNORE_DUP_KEYgoinsert into a_src values(1)insert into a_src values(1)insert into a_src values(2)--insert into a_src values(-1)gocreate trigger a4ins on afor insertasselect * from insertedgocreate trigger afterins on aafter insertasselect * from insertedgoinsert into a select * from a_srcgodrop table adrop table a_srcI'm gettingi-----------12(2 row(s) affected)Server: Msg 3604, Level 16, State 1, Procedure a4ins, Line 4Duplicate key was ignored.i-----------12(2 row(s) affected)even the inserted quasi tables are identical.If I uncomment insert into a_src values(-1), I'm gettingServer: Msg 547, Level 16, State 1, Line 1INSERT statement conflicted with COLUMN CHECK constraint'CK__a__i__58FC18A6'.

Hi there I' d like to make a trigger which will come with some kind of message ( maybe jscript?) or printout, each time I insert new client into the Client table. Clent table has ClientID, ClientName, Address, EMail, and ContactPerson. Please help
I have a situation where I need to create an insert trigger on table a which will create a corresponding record in table b. However before I insert the record i must obtain the max value for the record in table b and increment it by one. I have all this working. My question is if I just put a begin and commit with this statement is there a chance that when 2 users insert at the same time the max value may be incorrect say for instance
CREATE TRIGGER tr_cms_prov_ins ON provider FOR INSERT as declare @ndentPrid char(3), @nxtgenPrid char(7), @fname varchar(40), @lname varchar(40) begin tran select @ndentPrid = max(provider_id) from providerdnt if @ndentPrid is null set @ndentPrid = 1 else set @ndentPrid = @ndentPrid + 1
insert into dental..provider (provider_id, first_name, last_name, collections_go_to) select @ndentPrid, first_name, last_name','YYYYYYYYYYYYYYYNNNNN' from inserted commit tran
Will this do it or do I need to enforce some type of locking to handle the max value. There are no inserts into table b directly only by the trigger insert on table a
Hello all, I'm in the process of debugging a trigger i've written (which hasn't been any fun) and i have a question.
records for the table with the trigger are only inserted from a SP using an INSERT INTO ... SELECT statement. Multiple rows at a time.
question is.. does the trigger fire once for that insert into ... select or does it fire for each new row inserted by that statement. I was under the impression that it fires for each row but i'm not sure now because the table the trigger inserts to only has one row after the SP is run.
I created a trigger which looks like Create TRIGGER UpdateGenTables3 ON AWSWQ_Quizzes After insert as Begin SET NOCOUNT ON declare @TableName varchar(20),@Title varchar(20),@code varchar(20),@Gcode varchar(20),@uppercode varchar(20), @Description varchar(50) DECLARE DemoCursor CURSOR FOR Select QuizID,QuizTitle from AWSWQ_Quizzes group by QuizID,QuizTitle OPEN DemoCursor FETCH Next From DemoCursor INTO @code,@Title WHILE @@FETCH_STATUS = 0 BEGIN
INSERT INTO gen_tables (TABLE_NAME, CODE, SUBSTITUTE,UPPER_CODE,DESCRIPTION,OBSOLETE_DESCRIPTION) VALUES ('PRE_REQ_TESTS', @code, '', @code, @title, '') FETCH Next From DemoCursor INTO @code,@Title END CLOSE DemoCursor DEALLOCATE DemoCursor
end
The problem with my trigger is .I am not able to insert into my table AWSWQ_Quizzes the error i get when i try to insert is
Violation of PRIMARY KEY constraint 'pkGen_TablesTABLE_NAME'. Cannot insert duplicate key in object 'Gen_Tables'. The statement has been terminated. ---> System.Data.SqlClient.SqlException: Violation of PRIMARY KEY constraint 'pkGen_TablesTABLE_NAME'. Cannot insert duplicate key in object 'Gen_Tables'.
I have been trying to implement a trigger that is fired when a record is inserted in a table, provided that certain fields in the inserted record meet specific criteria (what you'd find in a where clause). All examples I have come across so far involve cases where the trigger is fired off everytime there is an insert regardless of what values are being inserted.
Basically, Assume a table "Address" with colums House Number, Street Name, City, State, Zip Code. How do I make my trigger fire ONLY when a record with City = 'Boston' is inserted??
How do I set up an insert trigger to copy all of the inserted data to another table? In other words, when someone adds a new paramater in the params table, I want to automatically create a matching set of data in the goals table. Thanks,Krista
SQL Server 2000 : I have a series of tables which all have the samestructure. When any of these tables are modified I need to syncrhoniseall of those modifications with one other table wich is a sort of mergeof the individual tables with one extra column.For most of these tables this is not a problem. The problem arriveswhen one of the tables has an ntext column which obviously can not beused in an update or insert trigger.Here's an example of one of them:CREATE TABLE tblImages(ID INT IDENTITY(1,1) PRIMARY KEY,Inventory nvarchar(8) NOT NULL,Coll nvarchar(8) NOT NULL,ImageFile nvarchar(128) NOT NULL,ImageNotes ntext NULL,TS timestamp NULLCONSTRAINT U_Images UNIQUE NONCLUSTERED (ItemCode, Inventory, Coll,ImageFile)I then had created an update trigger which looked like this:CREATE TRIGGER COLLNAME_UTRIGGER ON COLLNAME_ImagesFOR UPDATEASBEGINUPDATE tblImages SETInventory = inserted.Inventory,Coll = 'COLLNAME',ImageFile = inserted.ImageFileName,FROM inserted INNER JOIN tblImages ON inserted.ItemCode =tblImages.ItemCode ANDinserted.Invventory = tblImages.Invventory AND tblImages.Coll ='COLLNAME' ANDinserted.ImageFileName = tblImages.ImageFileUPDATE tblImagesSET ImageNotes=inserted.NotesFROM inserted INNER JOIN tblImages ON inserted.ItemCode =tblImages.ItemCode ANDinserted.Inventory= tblImages.Inventory AND tblImages.Coll ='COLLNAME' ANDinserted.ImageFileName = tblImages.ImageFileEND " & vbCrLf)The first update in my trigger, be it an update or insert trigger,works fine. It crashes with the "Cannot use text, ntext or imagecolumns in the 'inserted' or 'deleted' tables." error in the secondpart.I have read various messages through the Internet on this and severalof them reference using INSTEAD OF triggers and views. I have neverused those before as this is my first work with SQL 2000. None of theexamples of INSTEAD OF triggers I have seen yet use the actual insertedtables and I haven't quite understood how to use them correctly.Can someone help me with the basic syntax as this trigger is one ofseveral that I am going to have to get working.Thank you in advance for any help, assistance, suggestions or"direction pointing" you may provide.
I wrote a trigger that works fine when I insert record by record in the DB. However, when I run a Stored Proc to insert a bunch of records at the same time, the trigger only works for the last record.
Anyone has a clue or a possible solution. The trigger is well tested and works fine.
Hi everybody,I just wrote my first two triggers and from the minimal amount of testing Ihave done, they work! However, I was hoping I could get some feedback fromthose of you more experienced in writing triggers.Here is the first one:CREATE TRIGGER DecreInters ON InteractionFOR DELETEASdeclare @stu INTdeclare @num INTselect @stu = Student_FK from deletedselect @num = (select Inters from Student where Student_Key = @stu)UPDATE StudentSET Inters = @num - 1FROM StudentWHERE Student.Student_Key = @stuHere is the second one:CREATE TRIGGER IncreIntersON InteractionAFTER INSERTASdeclare @stu INTdeclare @num INTdeclare @last_rec INTselect @last_rec = @@IDENTITYselect @stu = (select Student_FK from Interaction where Interaction_ID =@last_rec)select @num = (select Inters from Student where Student_Key = @stu)UPDATE StudentSET Inters = @num + 1FROM StudentWHERE Student.Student_Key = @stuAre there any shortcuts I could use or things I could do to make thesetriggers more efficient. Please give me some feedback and let me know ofany problems that might possibly be caused due to my doing this improperly.Thanks ahead,Corey
I recently moved a database from a SQL server 2005 box to new server running SQL server 2012. The update/insert triggers that were working on the tables to handle referential integrity checking are no longer working. Running the same database on SQL Server 2008 and everything works.
Here is one of the trigger that throws the error 44446
USE [M2Data] GO /****** Object:Â Trigger [dbo].[tblContacts_UTrig]Â Â Â Script Date: 3/11/2014 9:07:13 AM ******/ SET ANSI_NULLS ON
[code]....
I have verified that there is a matching key in tblCompanys. Also, when I run a query to update tblContacts the error message appears but the update does take. If I try and edit the row directly by selecting edit top 200 rows - the error message appears and the update does NOT take.
These triggers were probably added to the database during an upsize from MS Access to SQL Server 7 way back. What am I missing - is it something in the syntax?
I want to be able to duplicate every single record that is inserted or updated in a particular table to another table, but not the delete. Is the best way to set-up a trigger? If so can anyone provide me with an example of how to do this? Also could you just duplicate certain columns in the row I would you have to do all columns?
This isn€™t an problem as such, it€™s more of a debate.
If a table needs a number of update triggers which do differing tasks, should these triggers be separated out or encapsulated into one all encompassing trigger. Speaking in terms of performance, it doesn€™t make much of an improvement doing either depending upon the tasks performed. I was wondering in terms of maintenance and best practice etc. My view is that if the triggers do totally differing tasks they should be a trigger each on their own.

Is it possible to achieve this using triggers:When someone tries to delete a row in table A, the trigger should first delete a corresponding row in table B and then delete the row in table A. The reason being that, there is a foreign key set on Table B that references table A. So any attempt to delete a row in table A without deleting the corresponding row from B, throws an error.
Hello All, I have to write Trigger for Update, I have two tables, one is for storing records of current values, and one is for storing history of values. How to Write a Trigger on Main Table. As we have Inserted and Deleted Tables through which we can find Values, We dont have any Table for UPDATED Values. Help me. General Problem
I need to create a set of rows every time a new row is inserted into a table. Example (I think this would work)... select @insertedId = column1 from insertedselect @id = column1 from table1 where column2 in (select column1 from table2 where column2 = @insertedId)insert into table3 values(x, y, @id) Is it possible to do the same kind of thing in a situation where the select statement returns multiple values and execute the insert statement for each of these values? Also, if table3 was in fact the table on which the trigger acts, would it then be executed for every row created by the trigger? Sorry if I sound confused. I am.

Hi using triggers i try to insert some values in to my 2 tables: But its showing teh error as "The request for procedure 'Triginsert123s' failed because 'Triginsert123s' is a trigger object." This is my code in back end: sqlcon.Open() Dim cmd As New SqlCommand("Triginsert123s '" & txtID.Text & "','" & txtName.Text & "','" & txtRole.Text & "','" & txtDep.Text & "'", sqlcon) cmd.ExecuteNonQuery() sqlcon.Close() My trigger is: CREATE TRIGGER Triginsert123s ON [dbo].[EmpRole] FOR INSERT AS declare @Eid as tinyint, @Ename as varchar(50), @Role as char(10) Insert into Emprole(Eid,Ename,Role) values(@Eid,@Ename,@Role) insert into empdep(eid,dep) values(@eid,@Role) Whats the probs?, Plz i am new to triggers help me,
Hi All, I'm using triggers to handle my transaction log to cature inserts and updates. It works fine except if the user clicks on the Save button more than once, the trigger is fired and the record is written to the log even if the record wasn't changed. Does anyone know how to check if the record was actually changed so that it isn't written to the table if it wasn't?
When I execute a stored proc from my asp.net page, will the results of a trigger be returned to my program?
For instance say my stored proc is:
Update Employees set (Lastname = @Lastname) where ID = @ID
And my trigger is:
CREATE TRIGGER tr_Employees_U on Employees FOR UPDATE AS IF UPDATE(lastname) BEGIN RAISERROR ('cannot change lastname', 16, 1) ROLLBACK TRAN RETURN END GO
It seems like since this is an AFTER trigger that my webpage would actually get a valid return code from my stored procedure however the trigger would rollback those changes correct? Or would the trigger get fired and send it's return code to my webpage?
I'm trying to write an instead of trigger for a view in SqlExpress...the table and views are defined as such:CREATE TABLE [dbo].[Work]( [WorkID] [int] IDENTITY(1,1) Primary Key, [ResourceID] [int] NOT NULL, [TaskID] [int] NOT NULL, [WorkDate] [datetime] NOT NULL, [WorkQuantity] [float] NOT NULL, [IsEstimate] [bit] NOT NULL DEFAULT ((0)), [Project] [int] NOT NULL,);CREATE VIEW [dbo].[ActualWork]ASSELECT WorkID, ResourceID, TaskID, WorkDate, WorkQuantity, ProjectFROM dbo.[Work]WHERE (IsEstimate = 0);CREATE VIEW [dbo].[EstimatedWork]ASSELECT WorkID, ResourceID, TaskID, WorkDate, WorkQuantity, ProjectFROM dbo.[Work]WHERE (IsEstimate = 1);Given that, what is wrong with the following create trigger statement:Create Trigger trg_InsertActualWork ondbo.ActualWork Instead of InsertasBEGIN Insert into dbo.Work( ResourceID, TaskID, Project, WorkDate, WorkQuantity, IsEstimate ) values ( inserted.ResourceID, inserted.TaskID, inserted.Project, inserted.WorkDate, inserted.WorkQuantity, 0 );END
l'm trying to build a trigger on a table. The reason for the trigger is to check a certain field for the first three characters if it has ie abc it must update another field in this case loanbook to newabc.How do l write the trigger so that it also check if exists and perform the updates. Please help its Urgent. l've listed the trigger below.
CREATE TRIGGER UpdTest_TRGData ON Test_TRG FOR insert,Update AS
IF left('Loan_No',3)='ABC' update Test_TRG set loanbook = 'NEWABC'
else
IF left('Loan_No',3)='DEF' update Test_TRG set loanbook = 'NEWDEF' where loanbook is null
else
update Test_TRG set loanbook =left('Loan_No',3) where loanbook is null
I'm a bit confused on this bit please elaborate : " FROM Test_TRG t INNER JOIN inserted i ON t.PK = i.PK ". The PK is on which field? Basically this trigger should ensure that on insertion of o new loan if The left(loan_no,3)=MCG and its null then NEWMCG left(loan_no,3)=MCG and its null then NEWMCG left(loan_no,3)=KVS and its null then NEWKVS left(loan_no,3)=MFS and its null then MFS left(loan_no,3)=TCR and its null then TCR left(loan_no,3)=ABL and its null then ABL
Listed below is what l've tried to do but l'm missing the PK part.Otherwise everything else you explained in the script is clear. Thanks man its urgent. When l parse the query its fine , but When l run it l get an error.
CREATE TRIGGER UpdTest_TRGData ON Test_TRG FOR INSERT, UPDATE AS
UPDATE Test_TRG SET LoanBook = CASE WHEN LEFT( i.Loan_No, 3 ) = 'MCG' THEN 'NewMCG' WHEN LEFT( i.Loan_No, 3 ) = 'KVS' AND i.LoanBook IS NULL THEN 'NewKVS' WHEN LEFT( i.Loan_No, 3 ) = 'MFS' AND i.LoanBook IS NULL THEN 'MFS' WHEN LEFT( i.Loan_No, 3 ) = 'ABL' AND i.LoanBook IS NULL THEN 'ABL'
WHEN i.LoanBook IS NULL THEN LEFT( i.Loan_No, 3 ) END FROM Test_TRG t INNER JOIN inserted i ON t.PK = i.PK -- Fill in Primary Key or other Join Column(s) WHERE LEFT( i.Loan_No, 3 ) = 'MCG' OR ( LEFT( i.Loan_No, 3 ) = 'KVS' AND i.LoanBook IS NULL ) OR i.LoanBook IS NULL
====== Error message =================
Server: Msg 207, Level 16, State 3, Procedure UpdTest_TRGData, Line 11 Invalid column name 'PK'. Server: Msg 207, Level 16, State 1, Procedure UpdTest_TRGData, Line 11 Invalid column name 'PK'.
I an loading records from a flat file into a table, which is done everyday by a scheduled job in SQL Server 7.0.
How can I make sure that if the job is run twice in a day for some reason that the same rows are not inserted into the table again? Do I have to write a insert trigger on the table ??? If so how can I achive the objective ??
I'm working on trying to figure out how to update the child table from the parent via a trigger. This works fine as long as the value is in the child table. If it's not, then I get my foreign key violation. So, My next thought was to simply put in a begin tran / rollback tran within the trigger... My question is this : If I have multiple triggers on the parent table all based on the update of the key field (and the child tables... some 7 of them) all have FK's, if I rollback one trigger does it rollback the entire transaction? Or just the functionality of that trigger? From what I've read, it appears as if it's the entire transaction... if so, how do I get a trigger to 'ignore' itself or not fire based on a select criteria that i have within that same trigger...
