View 10 RepliesI'm tracking sales reps and the companies they represent. I have 2 tables. A header table that has the SalesRep (a key field) the name, phone, address, etc.A line file that will have the sales rep multiple times, each line having a vendor they represent.
SalesRepHeader table:
SalesRep name phone VendorList
Bob Bob_Smith 111-222-3333
John John_Young 123-456-56789
Mary Mary_Kerns 567-876-98765

Whenever the SalesRepLine file is added to or updated I want the header file field VendorList to be updated with a concat of the vendors for this sales rep so the SalesRepHeader file would look like this.
SalesRep name phone VendorList

Hello,
Anyone know how to create an update trigger where the primary key isn't fixed.
If the primary key change how can I tie together the Deleted and Inserted tables if more than one row is updated?

Im using a store proc in SQL server.I use one table to store my hockey statistics data of each player in the league.When i submit my form i would like to check if there is any sheet of that player that allready exist .. If so then i do update.. if it does not exist i do the insert statement.Here the way i figured it out ! One store proc to do the work of the insert or update. And one to check if the player exist in the statistics table. But i just cant find a way to return a good value from my second store proc. Does my logic make sence ? any ideas ?thank you<code>create procedure Hockey_Player_UpdateForwardStatistics
@LeagueID int, @GamePlayerID int, @Games int
as
declare @PlayerID int
@PlayerID = Hockey_CheckPlayerStatistics(@LeagueID, @GamePlayerID)
if @PlayerID = 0begininsert into Hockey_PlayerStatistics( Games)values( @Games)end
ELSE
beginupdate Hockey_PlayerStatistics set Games = @Gameswhere LeagueID = @LeagueID and PlayerID = @PlayerIDend</code>
I run the following statement and it will not update beyond 7 million plus rows and I have about 38 million to complete. I keep checking updated row counts and after 1/2 day it's still the same so I know something is wrong because it was rolling through no problem when I initiated it. I need to complete ASAP so it's adding to my frustration. The 'Acct_Num_CH' field is an encrypted field (fyi).
SET rowcount 10000
UPDATE [dbo].[CC_Info_T]
SET [Acct_Num_CH] = 'ayIWt6C8sgimC6t61EJ9d8BB3+bfIZ8v'
WHERE [Acct_Num_CH] IS NOT NULL

I had created a trigger which sees that whether a database is updated if it is its copy the values of the updated row into another control table now I want to read the content of control_table into BIzTalk and after reading I want to delete it.Can any one suggest the suitable ay to do this?

I have a big problem. If anyone can help.
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?
Is there any other way to do this?
can DBCC help to retrieve this info?
Please advise me how to do this.
Thanks in advance.

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?
Hi,
I am not sure if this is the right forum to post this question.
I run an update statement like "Update mytable set status='S' " on the SQL 2005 management Studio.
When I run "select * from mytable" for a few seconds all status = "S". After a few seconds all status turn to "H".
This is a behaviour when you have an update trigger for the table. But I don't see any triggers under this table.
What else would cause the database automatically change my update?
Could there be any other place I should look for an update trigger on this table?
Thanks,
Hello
I've to write an trigger for the following action
When a entry is done in the table Adoscat79 having in the index field Statut_tiers the valeur 1 and a date in data_cloture for a customer xyz
all the entries in the same table where the no_tiers is the same as the one entered (many entriers) should have those both field updated
statut_tiers to 1
and date_cloture to the same date as entered
the same action has to be done when an update is done and the valeur is set to 1 for the statut_tiers and a date entered in the field date_clture
thank you for your help
I've never done a trigger before
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)
create trigger tr_cmsUpdt_meds on dbo.medisp for UPDATE as
if update(pstat)
begin
update med
set REC_FLAG = 2
from deleted dt
where med.uniq_id = dt.uniq_id
and dt.pstat = 2
and dt.spec_flag = 'kop'
end
I am trying to update a fields with an UPDATE statement but I keep getting the error message when I run the query.
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
I have this Update trigger that I know is causing the error message because I guess it's not built to manage multi-row updates.
Can someone help me re-write it. I also tried using the WHERE p.ID = p.ID but when I do that it modifies all rows in the modifieddate column instead of just the cells/rows that I'm updating
ALTER TRIGGER [dbo].[MultitrigCA]
ON [dbo].[ProdDesc]
AFTER UPDATE
AS
SET NOCOUNT ON
IF UPDATE (codeabbreviation)
UPDATE p
sET p.ModifiedDate = GETDATE()
FROM ProdDesc AS p
WHERE p.ID = (SELECT ID FROM inserted)

hi!
i have a database with about 20 tables. i appended to each table a column "UpdatedOn", and i want to write a trigger to set the date of the update date in that column, using a trigger.
i want to avoid the trigger launching for the last column (UpdatedOn).
how can i detect the rows that changed, and modify only the update date/time?
i read something about TableName_Inserted and TableName_Deleted, but i would prefer to copy as generic as possible the data from there, meaning, not to write column names in my script.
another idea i thought about was to prevent the trigger executing if no other column except for UpdatedOn changed, but... i encounter some trouble, when i try to pass column name (as string) to UPDATE() function.(Error: Expecting ID or QUOTED_ID)
thank you in advance.
Stepping thru the code with the debugger shows the dataset rows being deleted.
After executing the code, and getting to the page presentation. Then I stop the debug and start the
page creation process again ( Page_Load ). The database still has the original deleted dataset rows.
Adding rows works, then updating works fine, but deleting rows, does not seem to work.
The dataset is configured to send the DataSet updates to the database. Use the standard wizard to create the dataSet.
cDependChildTA.Fill(cDependChildDs._ClientDependentChild, UserId); rowCountDb = cDependChildDs._ClientDependentChild.Count; for (row = 0; row < rowCountDb; row++) { dr_dependentChild = cDependChildDs._ClientDependentChild.Rows[0]; dr_dependentChild.Delete(); //cDependChildDs._ClientDependentChild.Rows.RemoveAt(0); //cDependChildDs._ClientDependentChild.Rows.Remove(0); /* update the Client Process Table Adapter*/ // cDependChildTA.Update(cDependChildDs._ClientDependentChild); // cDependChildTA.Update(cDependChildDs._ClientDependentChild); }
/* zero rows in the DataSet at this point */ /* update the Child Table Adapter */ cDependChildTA.Update(cDependChildDs._ClientDependentChild);
Hi i've searched a lot with no results, im trying to do a trigger, this is the scenario
Got 3 tables, Product, Lines, Sublines
If Update Multiple sublines it should be updated to the products table, but i cant because the inserted table has multiple rows, the only way to do this is using cursors???
(Note, i cant do this using cascade because there are others, if i include this get a circular problem so i have to solve this other way)
is there a Trigger that monitors updated rows? I would like to run a
insert into sometable (pkcolumnname)
select pkcolumnname from monitoredtable where ????
"i dont know what goes here to only get value of rows that have been updated"
Hello All,
I've been adviced without much detail that the best way to handle updates is with an Update Trigger to write to an AuditTable.
I always thought it was better to avoid triggers.
I'm getting confused very fast in reading about triggers.
Could someone please point me in the right direction?
Thank you,
Tina
i am using address table to store the address of employees, agents, students; so can't use cascade update and delete. so i decided to use trigger but i got stuck here as well.
Here employeeid is the PK of employee id. so when it is updated, i want to update that id in corresponding address table as well.
so what i need is to find out the previous value of EmployeeID before updating to use in WHERE clause and new EmployeeID to use in SET clause.
<code>
CREATE TRIGGER [AddressUpdate] ON [dbo].[MCS_Employee]
FOR UPDATE
AS
IF UPDATE(EmployeeID)
BEGIN
UPDATE MCS_Address SET EmployeeID = 'i am stuck here; how to know the previous value?
WHERE EmployeeID = ???
END
</end>
ironically, PK in my table can be updateable as well.
Hello all. I have a table which is the exact replication of a different table. Now if an update takes place in the original table I want to copy that row into the new table without the update.I have this but I am not sure if it works.Create Trigger Content_Archive on content
For Update
As
Insert Into content_audit Select * From DeletedI dont know if Updated exists so I am using Deleted. It is returning both rows (before and after update). And the insert should take place as soon as an update takes place in any field in the content table.
Hello, I have two tables, looks as follow.
TOPIC
------
TOPIC_ID
STATUS_ID
TOPIC
THREAD
-------
THREAD_ID
TOPIC_ID
STATUS_ID
THREAD
THREAD_DATE
NAME
I want to update STATUS_ID in TOPIC when I post a new THREAD.
I guess the best would be to use a trigger?
Don't know much how you write them so if someone please could help or point me in right direction.
My plan is to always show the updated STATUS_ID in TOPIC while I have history in the THREAD TBL.
I am using MS SQL 7.0
Thanks for a great site.

I have an update trigger on a table on my transactional database that inserts a row of data into another database (audit database)for any modification made on the transactional database.
So if i modify a row on tran db it will write the data modified as a new row in the audit db.
This works fine if I am updating only 1 row with each Update statement. However if I update more than 1 row (multiple rows) with the same Update statement, the update trigger only inserts the last row modified in the audit database. So I lose record of any other rows modified with the same update statement.
Is there a way by which i can change my Update trigger or something, so I get all the rows updated by 1 update statement inmy audit database???
Thanks a bunch,
Judy

Is there a way I can get the old value of a specific field when using an update trigger?
e.g. I want to use the condition 'If Update(Column) '
in odrer to create a logfile which stores the old and new value of a field.
The new value can be get from a Select from Inserted table.
Is there a way I can get the old value (before update) also??

Hallo there,
I'm totally new to writing triggers, but managed to get a trigger to update a specific column (ufINCTcost) on change of another column (ufINCKm)
My problem is that the trigger performs this update on ALL rows, which makes it very slow. How can I get it to only update the column on the row where the change was made ?
My trigger looks as follows:
CREATE TRIGGER updateincidents ON [dbo].[_rtblIncidents]
FOR UPDATE, INSERT
AS
IF UPDATE (ufINCKm)
BEGIN
UPDATE dbo._rtblIncidents
SET ufINCTcost=dbo._rtblIncidents.ufINCKm+dbo._rtblInc idents.ufINCToll+dbo._rtblIncidents.ufINCParking+d bo._rtblIncidents.ufINCFlight+dbo._rtblIncidents.u fINCRental
Hope you can help !!
