Triggers - Run For Multiple Updated
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

Using Triggers To Get Recently Updated Info In SQL Server 2000
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

Multiple Triggers On A Table Or Encapsulated Triggers
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. www.handleysonline.com

One Trigger Vs Multiple Triggers ?
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

Linked Reports Not Being Updated When Master Report Is Updated
Since updating to SQL Server 2005 SP2 I've noticed two things about Linked Reports. 1. I do a lot of 'Snapshot' reports. With SP-1 if I updated a master report and made any changes to the Parameter List - it undid all my custom parameter changes on linked versions (restored to the Master Reports Defaults). While this is no longer happening with SP2 - it is still 'unhiding' the parameters. 2. With SP-1 if I added/deleted columns or made other changes to the report structure - the linked reports would pick up on the changes with their next refresh. With SP-2 I'm finding that I have to 'Re-link' the linked report back to the master report before the changes are refreshed. This is very time consuming especially with each report having 8 or more Snapshot reports pre-set up. Am I missing something - or is this a 'bug'... Any help would be appreciated...

Triggers Prevent Updates To Multiple Records
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.

Multiple Update Triggers Or One Large Trigger With If's
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

SQL Help: Get The Record I Just Updated
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!!! Oliver

Help With Trigger: Updated Oct 11, 2005
Nevermind, I'll just use a stored procedure. Update: I've figured out what is going wrong now. I'm trying to find the subaccounts from the old invoice using the new invoicedate. This is doomed to fail! I've worked out a way to save the old invoice date in the C# programming, but is there anyway to make that value accessible to the trigger? Note that there will be nothing useful in the deleted table--this trigger is on inserts only. Any help is appreciated!
