Update One Table When Records Inserted In Another Table - Variables In Trigger
May 19, 2014
I am trying to update one table when records are inserted in another table.
I have added the following trigger to the table “ProdTr” and every time a record is added I want to update the field “Qty3” in the table “ActInf” with a value from the inserted record.
My problem appears to be that I am unable to fill the variables with values, and I cannot understand why it isn’t working, my code is:
ALTER trigger [dbo].[antall_liter] on [dbo].[ProdTr]
for insert
as
begin
declare @liter as decimal(28,6)
I want to insert a row for a Global user in Table 'A' whenever ADO.Net code inserts a Local user row into same table. I recommended using a trigger to implement this functionality, but the DBA was against it, saying that stored proecedures should be used, since triggers are unreliable and slow down the system by placing unecessary locks on the table. Is this true OR the DBA is saying something wrong? My thinking is that Microsoft will never include triggers if they are unreliable and the DBA is just wanting to offload the extra DBA task of triggers to the programmer so that a stored procedure is getting called, so he has less headache on his hands.Thanks
I want to pass the 'inserted' table from a trigger into an SP, I think I need to do this by dumping inserted table into a temporary table and passing the temp table. However, I need to do this for many tables, and don't want to list all the column names for each table/trigger (maintenance nightmare).
Can I dump the 'inserted' table to a temp table WITHOUT specifying the column names?
hi, i am writing a trigger to log inserts,updates and deletes in a table and would like to also enter the user details ie who did the transaction. is the spid in the inserted table? if not how do i get this information?
I am trying to create a trigger on a table but when I check the syntax it tells me that "The column prefix 'inserted' does not match with a table name or alias used in this query"
CREATE TRIGGER trg_Structural_GenerateBarcode ON [dbo].[tbStructuralComponentSchedule] AFTER INSERT AS DECLARE @iCount int, @cBarcode char (25), @cCode char(4) DECLARE @cProject char(7), @cComponent char(10), @iEntryID int
I like to use the table "Inserted" within exec(), but it doesn't work because the scope is different. Does anyone have some sort of solution to this problem? The reason I am doing it this way is because I have a table consist of 200+ columns of bit types that contains permission information (The worest design i have ever seen!).
Code Snippet --gather column names
declare @ScreenPermissions nvarchar(256)
declare c_Permission cursor for SELECT [name] FROM syscolumns WHERE id = ( SELECT id FROM sysobjects WHERE type = 'U' AND [NAME] = 'ScreenPermissions' ) and [name] like 'Allow%'
open c_Permission fetch next from c_Permission into @ScreenPermissions while @@fetch_status = 0 begin
exec('INSERT INTO EmployeeInRoles (EmployeeID, RoleID) ' + 'select i.EmployeeID, r.RoleID ' + 'from inserted as i ' + ' inner join ScreenPermissions AS sp on sp.EmployeeID = i.EmployeeID and sp.' + @ScreenPermissions + ' = 1 ' + ' inner join Roles AS r on r.LoweredRoleName = Lower(' + '''' + @ScreenPermissions + '''' + ')' )
fetch next from c_Permission into @ScreenPermissions end close c_Permission DEALLOCATE c_Permission
Hi SQL fans,I realized that I often encounter the same situation in a relationdatabase context, where I really don't know what to do. Here is anexample, where I have 2 tables as follow:__________________________________________ | PortfolioTitle|| Portfolio |+----------------------------------------++-----------------------------+ | tfolio_id (int)|| folio_id (int) |<<-PK----FK--| tfolio_idfolio (int)|| folio_name (varchar) | | tfolio_idtitle (int)|--FK----PK->>[ Titles]+-----------------------------+ | tfolio_weight(decimal(6,5)) |+-----------------------------------------+Note that I also have a "Titles" tables (hence the tfolio_idtitlelink).My problem is : When I update a portfolio, I must update all theassociated titles in it. That means that titles can be either removedfrom the portfolio (a folio does not support the title anymore), addedto it (a new title is supported by the folio) or simply updated (atitle stays in the portfolio, but has its weight changed)For example, if the portfolio #2 would contain :[ PortfolioTitle ]id | idFolio | idTitre | poids1 2 1 102 2 2 203 2 3 30and I must update the PortfolioTitle based on these values :idFolio | idTitre | poids2 2 202 3 352 4 40then I should1 ) remove the title #1 from the folio by deleting its entry in thePortfolioTitle table2 ) update the title #2 (weight from 30 to 35)3 ) add the title #4 to the folioFor now, the only way I've found to do this is delete all the entriesof the related folio (e.g.: DELETE TitrePortefeuille WHERE idFolio =2), and then insert new values for each entry based on the new givenvalues.Is there a way to better manage this by detecting which value has to beinserted/updated/deleted?And this applies to many situation :(If you need other examples, I can give you.thanks a lot!ibiza
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.
Within a trigger, I'm trying to create a unique table name (using the NEWID()) which I can store the data that is found in the inserted and deleted tables.
I am sure someone must have run into this before. I have a couple of tables with a parent child relationship.
I created a trigger on the insert of the parent but don't want it to fire until both the parent and child have been inserted into.
However sometimes the child may not get inserted in to at all. In other words it is a 1 to 0 or more relationship.
I created the whole insert into the parent and the child and wrapped it all up in a transaction hoping that the trigger would not fire until the transaction actually completed.
However such is not the case and it fires when the parent is inserted into but nothing is inserted into the child yet even though that is part of the transaction.
Is it possible to postpone trigger fire until after both parent and child table values have been inserted?
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:
No row was updated the data in row 1 was not committed Error source .Net SqlClient Data provider. Error Message: the operation could not be performed because OLE DB provider "SQLNCLI10" for linked server "(null)" returned message "The partner transaction manager has disabled its support for remote/network transaction.".
correct the errors entry or press ESC to cancel the change(s).
I'm a newbie have trouble using the "inserted" table in a trigger. When I run these SQL statements:CREATE DATABASE foobarGOUSE foobar GOCREATE TABLE foo ( fooID int IDENTITY (1, 1) NOT NULL, lastUpdated datetime, lastValue int, PRIMARY KEY(fooID))GOCREATE TABLE bar ( barID int IDENTITY (1, 1) NOT NULL, fooID int NOT NULL, [value] int NOT NULL, updated datetime NOT NULL DEFAULT (getdate()), primary key(barID), foreign key(fooID) references foo (fooID))GOCREATE TRIGGER onInsertBarUpdateFoo ON Bar FOR INSERTAS UPDATE Foo SET lastUpdated = inserted.updated, lastValue = inserted.[Value] WHERE foo.fooID = inserted.fooIDGO
I get the error message:
Msg 4104, Level 16, State 1, Procedure onInsertBarUpdateFoo, Line 4 The multi-part identifier "inserted.fooID" could not be bound.
I can get the trigger to work fine as long as I don't reference "inserted".
What am I missing?
I'm using Microsoft SQL Server Management Studio Express 9.00.2047.00 and SQL Express 9.0.1399
I have a sql sever 2005 express table with an automatically incremented primary key field. I use a Detailsview to insert new records and on the Detailsview itemInserted event, i send out automated notification emails. I then received two automated emails(indicating two records have been inserted) but looking at the database, the records are not there. Whats confusing me is that even the tables primary key field had been incremented by two, an indication that indeed the two records should actually be in table. Recovering these records is not abig deal because i can re-enter them but iam wondering what the possible cause is. How come the id field was even incremented and the records are not there yet iam 100% sure no one deleted them. Its only me who can delete a record. And then how come i insert new records now and they are all there in the database but now with two id numbers for those missing records skipped. Its not crucial data but for my learning, i feel i deserve understanding why it happened because next time, it might be costly.
I have a scenario where I have to Update a table with date when there are new records in another table
For example:
I load ODS table with the data from a file in SSIS. the file has CustomerID and other columns.
Now, when there is new record for any customerID in Ods, then Update the dbo table with the most recent record for every CustomerID(i.e. update the date column in dbo for that customerID). Also Include an Identifier that relates back to the ODS table. How do I do this?
I really need your help now, and I know I can always count on this group for tough answers to tough questions. OK, here's my dilemma. I have my trigger, which upon a record being inserted into db1.table1, inserts the same record into db2.table2 (SQL 7 db on the same server). What's happening is only a few of the fields are getting over there, but most are ending up NULL or 0. Everything besides the following records are inserting into the other database table properly:
Note: The following fields have their Default Value set to (0) SystemID EventStatusID Coop NewProductFlag TVSupportFlag RadioSupportFlag FSISupportFlag RollbackPricing PleaseContactFlag
Default Value set to (1): KitInformationID
Here is the trigger:

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'
We have an app that uses triggers for auditing. Is there a way to know the order that the records were inserted or deleted? Or maybe a clearer question is.... Can the trigger figure out if it was invoked for a transaction that "inserted and then deleted" a record versus "deleted and then inserted" a record? The order of these is important to our auding.
When i debug a trigger is it possible to add a WATCHon the INSERTED or DELETED?I think not, at least I couldn't figure out a way to do so.Does someone have a suggestion on how I can see the values?I did try to do something likeINSERT INTO TABLE1(NAME)SELECT NAME FROM INSERTEDbut this didn't work. When the trigger completed and Iwent to see the TABLE1, there were no records in it.Are there any documents, web links that describe waysof debugging the trigger's INSERTED and DELETED?Thank you
HiI'm using the SQL 2000 table variable to hold 2 different fact sets.I'm declaring the variable @CurrentTable and inserting into it using aSELECT statement with no problems.I'm leaving certain of the columns null in order to later update themwith the PK.Problem is in the UPDATE syntax I'm usingUPDATE @CurrentTableSET ManagerTitle = (select mgrs.pos_title from mgrs) wheremgrs.pos_num = @CurrentTable.MgrPosNumIt is insisting I declare the @CurrentTable variable when I try to useit in the where clause.Is it simply out-of-scope or am I really doing something foolish?Andrew
I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?
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)
This field is a drop down list , after insert committed , i want other user defined field to populate.
Scenario. Drop down is a list of users, after selecting and updating then i want contact details of the above selected user be populated.
CREATE TRIGGER User_Defined_field_KAE ON [dbo].[AMGR_User_Fields_Tbl] AFTER INSERT
AS
INSERT INTO [dbo].[AMGR_User_Fields_Tbl] (Client_Id, Type_Id, name SELECT Client_Id, '1089', A.USER_PHONE_1 FROM inserted , [dbo].[ADMN_User_Details] as A WHERE name = a.user_id;
I am trying to update all recors in one table with records from another table. My script is only updating one record. How do I fix this? This is what I have:
Code:
set rec1=con.execute ("SELECT * FROM Cancels ORDER BY Canceldate ASC")
I am having a hard time understanding triggers. My goal is to put a trigger on table x where records are UPDATED or DELETED. When this trigger fires I need to take the record ID and put the ID modified record into table y with the date modified. so basically logging the recordid changed with the getDate()
I don't quite understand how to get the rowid of the modified record.
I have a trigger on an orders table. It checks against a patientmaster table to see if the sentflag is set to n or y. If it is "n" I need to push a record to a table on a separate db table. The user has permissions on the orders table. Without having the user be added and given permissions on the second db and table, what would be the best approach inside the trigger to handle this. I am using nt/sql security for this
