How Is Represented The Updated Table In A Trigger?
Feb 14, 2007
Hello
I am a newbie creating triggers and I would like to know what is the name of the updated logical table. That is, since the are identifiers like "inserted" and "deleted" that represent the inserted and deleted rows, respectivaly, I presumed that "updated" existed - but it does not.
I have a table with a column named "UpdatedTimeStamp" which I would like to update anytime the other columns are modified. I intended to create the following trigger:
create trigger myTrigger
on myTable
after update
as
update updated set UpdateTimeStamp=GetDate()
Of course, "updated" is not a valid identifier that represents the updated row.
Please, help me in creating this trigger. What is the correct way of doing a trigger like this?
Hi All, I am using a trigger. I want to get the data of a row before updating inside this trigger and insert it into a backup table. Please anybody help me. Example with code is highly appreciated.
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.
Hello, I am using SQL Server 2005 and ASP.NET 2.0. We have a very simple content management system where we have to keep track of date last modified for each row in all of our content tables. I know there's a "timestamp" datatype that is used for replication scenarios, but is there anything similar that I can use to set up a date_modified column for each of my content tables that will automatically update with GETDATE() whenever anything in a given row is updated? Or do I have to create a date_modified column of smalldatetime datatype and write a trigger on update for EVERY single table of content that I have in the database? It seems there should be an easier way to do this than to write 20 triggers for my 20 content tables. Thanks!
I am looking to created a trigger that inserts records into a log table to show the stored porcedure that has updated a specific column to a specific value in a specific table
At present I have:
CREATE TRIGGER [dbo].[trUpdaterTable] ON [dbo].[t_account]-- A DB level trigger FOR UPDATE --Event we want to capture AS IF update (document_status)
[Code] ...
However this doesn't appear to bring back the procedure that triggered the update...
The value the trigger should update on is document_status = 0
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.
Hi,I want to log updates to specific fields, storing the new and oldvalues. Is there any way I can iterate the collection of updatedfields within a trigger in order accomplish this?Thanks in advance,Julie Vazquez
We have a column syncUpdate in some tables and we need a trigger (or one for each table) which will set the current dateTime for the syncLastUpdate (dateTime) when either the row is inserted or updated (we have to ignore the syncLastUpdate column itself as this would be an infinite loop, I think).
I don't know much about DB but I think that is easly doable.
I am creating update trigger(After) on a table.I want to catch an updated row and insert the values of this row into a new table.How can i catch this row while creating a trigger after update.
I want to update several columns in different tables whenever an update is happend on specific table. I have a trigger for that which update all the relevant places when it fires.
I want to do this update only if certains columns were changed, otherwise - do anything, to reduce performance.
How Can I know which columns were updated inside the trigger? The tables has many columns and only if 2 of them were changed then I need to update other tables.
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.
I've done some searcing on this forum and online. I found one thread that talked about this problem, but it didn't seem to help me at all.
I have a package that downloads an xml file from a ftp server for processing. The file is named after the day that it was put on the ftp server. So, to help the situation I created a variable that gets set to the proper name before the FTP Task fires.
Now, I've been working with this SSIS task for just over 2 months and haven't seen this issue ONCE until I deployed it on the production helper server. All of my other SSIS tasks are working fine in my other Tasks.
I have set DelayValidation to true for the FTP Task, I have moved around the time the task gets run. This is what is really tricky. If I fire off the task manually (by running the batch file that runs all my tasks on the console) it works fine! I've ran it 3-4 times throughout the day manually and it works perfectly! However, whenever it is scheduled to be run in the middle of the night, it fails!
This problem has stumped me good. I can run the task manually, but when I run it scheduled, I get : File represented by "User::ftpXmlPath" does not exist.
I have a trigger set on TABLE1 so that any update to this column should set off trigger to write to the AUDIT log table, it works fine otherwise but not the very first time when table1 has null in the column. if i comment out
and i.req_fname <> d.req_fname from the where clause then it works fine the first time too. Seems like null value of the column is messing things up
Any thoughts?
Here is my t-sql
Insert into dbo.AUDIT (audit_req, audit_new_value, audit_field, audit_user)
select i.req_guid, i.req_fname, 'req_fname', IsNull(i.req_last_update_user,@default_user) as username from inserted i, deleted d
How can I determine who and when a table in a db was updated, I dont need this per record, I only need to know the last time an update was made to a table. Thanks.
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?
I am writing a generic trigger in VS 2005 that selects records from the inserted table, and updates an audit table. I am, however, unable to retrieve the name of the table that the insert occurred on. I am using the following code to select the records, and obtain the name.. Can anyone offer any alternatives to accomplishing this task? Thanks in advnace for any help you can provide.

I want to setup a method to get emailed whenever someone adds an item to a particular table.
I'm looking at SP's, and DTS's.. but i'm just not sure what the best path is.
http://www.sqldev.net/dts/SMTPTask.htm will create a great Custom DTS Email Task.. but then i don't know what to do next... I don't know how to say.. "If a new row is added, then run this DTS"... or if i should schedule the DTS to run every 30 minutes and then somehow query for new "Created" dates.

I am trying to find a global way of when the last time a row in one of my tables was updated or data inserted. I say global because I don't want to drill down through each table looking for modified rows.
