How Do I Update I Record In A Table Via A Trigger?
Nov 1, 2006
Am in a small fix. my Trigger is updating my entire table records , i don't want that, i want to update a column in the record that is updated by my application using a trigger that tracks updates on that table.
Is there a way i can track the updated record on my table and then update a field in that record through my TRIGGER?
My database is MSSQLServer2005 Enterprise Edition..
Below is my code
CREATE TRIGGER [TR_Employee]
ON [Test_1_1].[dbo].[Employee]
For UPDATE
Not For Replication
AS
BEGIN
Update Employee set Last_Changed = (select getDate())
Hi guys, may I know is it possible to create an update trigger like this ? Assuming there are two database, database A and database B and both are having same tables called 'Payments' table. I would like to update the Payments records on database A automatically after Payments records on database B had been updated. I can't use replication because both tables might having different records and some records are the same. Hope can get any assistance here, thank you.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
here is my trigger that i have right now the only problem is that it deletes the records before copying everything into the db i dont what do delete everything i just whant to catch the updated record and then update the other tables same record in the other db how would i do this:
right now i have this
CREATE TRIGGER test ON [dbo].[TEST123] AFTER INSERT, UPDATE, DELETE AS IF @@ROWCOUNT = 0 RETURN
IF (COLUMNS_UPDATED() & 2 = 2) DELETE FROM pubs..TEST123 WHERE test3 = '300' INSERT INTO pubs..TEST123 SELECT * FROM TEST123 WHERE test3 = '300' UPDATE pubs..TEST123 SET test1 = 'X' WHERE test1 IS NULL AND test3 = '300' UPDATE pubs..TEST123 SET test2 = 'X' WHERE test2 IS NULL AND test3 = '300' UPDATE pubs..TEST123 SET test3 = 'X'
Hello All,I have 2 tables in a MS SQL DB. Table1 and Table2.LogTable2.Log was a copy of Table1 + an extra column for date_deleted. Ihave 2 Triggers on Table1, Insert and delete. So when a record isinserted into Table1 it's copied onto Table2.log, and when deleted inTable1 the same record in Table2.log is time stamped with time ofdeletion.I would like to have another Trigger on Table1 for update. So if acertain field (not primary key) is updated for a record it is alsoupdated in Table2.log This way Table2.log will always have exactly thesame fields per record as Table1.I'm not sure how to reference the modified records only and updatejust the modified fields...something like...?----------------------------CREATE TRIGGER [tr_updateT_Log] ON [dbo].Table1FOR UPDATEASUpdate Table2.LogSET description = , office =-------------------------------------------------Any help would be greatly appreciatedThanksY
I have a parent table with 27 Columns and Child Table with 37 colums - when even there is an update in any of the columns on Parent or Child table, I require new record inserted into Audit_Parent and Audit_child table. Please help with SQL Code on Create Trigger and insert records into Audit_parent and Audit_child when an Update occurs on any of the columns. Insert into AuditParent and AuditChild should occur whenever there is an update on either Parent or child table.
I am new to SQL and these forums, so please bear with me :)
My basic question is if I can create a update trigger that will pull info from another record in the same table if data in certain fields match the existing record.
An example:
The user creates a new record. If said user enters data in specified fields that matches data in the same fields in another record in the same table, can a update trigger be used to fill out the rest of this record with the data from the record that matches?
If you need more Info on my problem, ask and I will try to explain better. There may be a better way of doing this than using a trigger, but I am not sure. The fields that I would use to match the data would not be the primary key fields.
Im using a trigger to check updates on particular table and execute a email. it works but it doesnt show the right record im looking into one table called SiteInfo. here is my code Im using sql 2005, can someone look at my code or the select statement.
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'
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?
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 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 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 have an update trigger which fires from a transactiion table to update a parent record in another table. I am getting no errors, but also no update. Any help appreciated (see script below)

To see where is the problem I am trying to count rows in the database.First I create a table A with 2 columns namely tablename, rowbefore and rowafter and I insert records in it as below.
INSERT INTO A SELECT TableName = o.name, '', Rows = max(i.rows) FROM sysobjects o INNER JOIN sysindexes i ON o.id = i.id WHERE xtype = 'u' AND OBJECTPROPERTY(o.id,N'IsUserTable') = 1 GROUP BY o.name ORDER BY o.name Then I update rowbefore with rowafter as below. UPDATE A SET rowbefore = rowafter
Now I launch my application with update records in the database.Then I am trying to update rowafter with new records as below.
UPDATE A SET rowafter = (SELECT max(sysindexes.rows) FROM sysobjects INNER JOIN sysindexes ON sysobjects.id = sysindexes.id WHERE xtype = 'u' AND OBJECTPROPERTY(sysobjects.id,N'IsUserTable') = 1 AND A.tablename = sysobjects.name)
Does this update really update my column rowafter or not?
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

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
Hi,I need to update a field in about 20 records on a table. The table hasan update trigger (which updates the [lastedited] field whenever arecord is updated). As a result I'm getting an error: "Subqueryreturned more than 1 value.", and the update fails.Is there a way in the stored procedure to handle this issue?thanks for your help.Paul
I have created a simple trigger that updates a table called documents in my database. When a row has been inserted it will change the field form_type to 'cabinet A' if a document_type is equal to 'form'.
Im fairly new to triggers and Im uncertain whether this trigger is updating the whole table or the new row? I only want the new row to be updated as the table is fairly large.
create trigger file_documents on documents_table after insert as begin update documents_table set cabinet = 'Cabinet A' where document_type = 'FORM' end
