Triggers - Run For Multiple Updated
Sep 24, 2005
I am new to trigger and I have following question.
I have two tables: "Customer" & "AccountDetails". "Customer" stored customer's personal information, so one customer will be at one row. "AccountDetails" stored all the accounts information which tie to each customer, so there will be multiple rows for a customer since one customer can have mulitple accounts.
Right now I have a updated trigger on "AccountDetails" table. When there is an updated to this table, it will insert some data to another "CustLog" table for logging when customer does the updates. Let's say Customer "A" has 5 accounts. When "A" updates his accounts' information, all 5 rows will be updated, triggers will be called 5 times, and 5 insert rows will be added to "CustLog". Is that any way to keep track those 5 updated on "AccountDetails" are referred to the same customer (by customer ID or so) so that it will only run the trigger once instead of 5 times?
I hope I make it clear and please help me on this! :o

Hello all,
I am trying to change values of two tables in my sql server 2000 database. When one of the tables is modified in some way like adding/updating a record, I need a trigger procedure to copy this new data from the first table to the second. Problem is, how do I get the newly inserted or updated data from the first table? How do I specify that I only want the data which caused the trigger to execute? Anyone know?
Thanks,
Bob

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.

This is what I have so far and it do and insert and does work and I have no idea where to begin to do an update stored procedure like this....
CREATE PROCEDURE AddDrawStats
AS
INSERT Drawing (WinnersWon,TicketsPlayed,Players,RegisterPlayers)
SELECT
WinnersWon = (SELECT Count(*) FROM Winner W INNER JOIN DrawSetting DS ON W.DrawingID = DS.CurrentDrawing WHERE W.DrawingID = DS.CurrentDrawing),
TicketsPlayed = (SELECT Count(*) FROM Ticket T INNER JOIN Student S ON T.AccountID = S.AccountID WHERE T.Active = 1),
Players = (SELECT Count(*) FROM Ticket T INNER JOIN Student S ON T.AccountID = S.AccountID WHERE T.AccountID = S.AccountID ),
RegisterPlayers = (SELECT Count(*) FROM Student S WHERE S.AccountID = S.AccountID )
FROM DrawSetting DS INNER JOIN Drawing D ON DS.CurrentDrawing = D.DrawingID
WHERE D.DrawingID = DS.CurrentDrawing
GO

I have a question regarding Triggers.
Lets say I want to create a trigger for Insert, Update and Delete action. For each action I do different things.
Now I can create a single trigger for Insert, delete and update, and using counts for inserted and deleted table, take the action appropriately.
Or I can create three different triggers each for Insrt, update and delete.
Which option is better for performance?
Thanks

I'm trying to use Query Analyzer to create several triggers on different files in the same sql script file. It appears to only allow me to create one trigger at a time in Query Analyzer. How do you separate multiple create trigger statements? Here what I'm trying to do:
CREATE TRIGGER PO_BOL_DELETE ON dbo.PO_BOL
FOR DELETE
AS
INSERT into PO_Back
SELECT *, host_name(), suser_name(), getdate()
FROM deleted
GO
CREATE TRIGGER RECEIPT_DELETE ON dbo.receipt
FOR DELETE
AS
INSERT into receipt_Back
SELECT *, host_name(), suser_name(), getdate()
FROM deleted
GO

I have a table "PageInfo" wich has columns "PageID, Title(has "AboutUs" as one of the values), DateModified, Active". My other table is "AboutUs" and has columns "ID, WhatsNew, Welcome, Active".
My goal here is that if table "AboutUs" is affected as an "INSERT" or an "UPDATE" on any row, I want "PageInfo.DateModified" WHERE "PageInfo.Title = AboutUs" to be updated with "getDate()". Don't know if I'm clear enough but thanks in advance.

I have triggers in place on a table that do various checks on data input. It is clear that because of these triggers I cannot do updates on multiple records in this table. When I do, I receive an error that "subquery returned more than one value." Is there anyway to work around this by temporarily turning off triggers or something else?
Many thanks for advice.

I have a table which when certain columns are updated, need a trigger to fire to update a next schedule date in that same table for that record. I can write the trigger, but my question for performance and efficiency is which approach would be better. Separate triggers fo the 8 columns, or a large trigger with an If to check if these columns are updated.
Thanks

Hi -
apologies if this is not the right forum for this - I've searched a bit and this seems to be the best fit.
I have the following problem: I want to update records in a table that fit certain criteria. The way the insert logic works make sure that there will always be only one record that fits the criteria and I'd like to get the ID value of that record once the update went through. So here is what I tried:
1 UPDATE Timeslot
2 SET StartTime = @StartTime, EndTime = @EndTime
3 WHERE (ProfessionalID = @ProfessionalID) AND (ProviderLocationID = @ProviderLocationID) AND (RequestID IS NULL) AND (StartTime > @StartTime) AND
4 (EndTime < @EndTime);
5 SELECT SCOPE_IDENTITY()
My hope was that the select scope_identity would return the Timeslot ID of the row that was affected, but it doesn't. How do I get that row?
Thanks!!!

Guys,
Is there a way to find out when a certain DB object (e.g. Stored procedure) was last modified?
SYSOBJECTS table contains crdate and refdate fields. None of these, however, appear to tell me when when the object was last updated.
Any suggestions?
Thanks a lot

I have a table written in to sql by the program Wincc flex wich is currently constantly saving data in to it. I want to reed this data back in to Labview and update it’s content on Labview constantly to plot a graph that keeps updating over time.
I have achieved this after some research but my problem is that I need a way of just reading the last row (meaning most recent row, not last row as the bottom one) inserted in to the table written by wincc and saved in sql WITHOUT having to read all the data and selecting for example the higest value of a timestamp column (which is added by wincc) because this would cause too much lag since the table has a lot of elements and I need to constantly read it. One of the main problems is that the data written by wincc is written in a circular buffer, which does delete 20% of the data when it fill’s up and start writing new data in to the free space, so that the temporal order of the data does nothing to do (at least nothing simple) with the index order in the table. Is there anything like a method to save the index of the last row modified in the table so that labview could read it and directly access the most recent recordset in the table just by index specification on a query?

However , I can see the data saved in the DataSet but not in the actual database.
If I try to insert the same user again , I got primary key violation ???
Here is the insert function :
string SqlConnection = @"Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|QJ.mdf;Integrated Security=True;User Instance=True";
SqlConnection Conn = new SqlConnection(SqlConnection);
SqlDataAdapter DataAdapter = new SqlDataAdapter("SELECT * FROM USERS", Conn);
SqlCommandBuilder ComandBuilder = new SqlCommandBuilder(DataAdapter);
DataAdapter.InsertCommand = ComandBuilder.GetInsertCommand();
DataAdapter.UpdateCommand = ComandBuilder.GetUpdateCommand();
DataSet DS = new DataSet();
DataAdapter.Fill(DS, "USERS");
DataTable DT = DS.Tables["USERS"];
DataRow DR = DT.NewRow();
DR["NAME"] = txtUserName.Text;
DR["Password"] = txtPass.Text;
DR["Type"] = 1;
DT.Rows.Add(DR);
DataAdapter.Update(DS,"USERS");
DS.AcceptChanges();
Conn.Close();
I dont know what I have done wrong
