I was asked this question due to performance issues..
If you update a 1 or two columns in table, what gets replicated?? Is it the whole row or just those columns that were updated??
I am trying to find this answer cause it will have an effect on the way we do some updates in the future.
Thanks...
also if you have any links to information about this that would be great.
Hi,
I'm using sql-2005.
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.
Many thanks,
Nira.
Greetings,
We have a standard audit trigger on one of our tables. The trigger type is "after insert, update". The trigger populates four table columns, telling us the login and time the row was created and last updated.
We use replication to synchronize three servers. The trigger specifies "not for replication" on all servers.
The code used to grab the identity and time of the last update is shown below.
LastEditedDate = GETUTCDATE(),
LastEditedBy = SUSER_SNAME()
What I observe is that the LastEditedBy value is sometimes different for the same row on different servers even though the time value is identical. I don't know how to explain this. It looks like the login value is being recalculated during replication while the edit time is not.
For the record, the correct login will be something like "MYDOMjoe" while the incorrect value on another server will read "NT AUTHORITYNETWORK SERVICE". Do these symptoms ring a bell with anyone?
Thanks,
BCB
There are times when we need to make DDL changes and have them NOT replicate to the subscription database. The documented approach is to disable DDL replication using sp_changepublication (replicate_ddl = 0). See http://msdn2.microsoft.com/en-us/ms147331.aspx
However, our DDL still replicates even when following those steps. I've even tried the very simple steps below to reproduce the error.
Set up transactional replication of one small test table. Replication is working fine.
Set @replicate_ddl = 0 with sp_changepublication. I manually verify the setting (using the GUI) before continuing.
Run a simple alter on the publication DB; change one column from varchar(25) to varchar(30). "ALTER TABLE <tablename> ALTER COLUMN <colname> VARCHAR(30) NULL".
The DDL still replicates. The subscription table still has the column altered to the new definition.
I've even tried manually setting the option in the GUI and also stopping and restarting the synchronization after changing the setting; nothing works.
We are using SQL Server 2005 and just upgraded to SP2 a few days ago.
I have not found any other articles/postings on the topic so it appears we are the only ones having this problem. If anyone has any advice or input, it is greatly appreciated.
Regards,
Adam
I have been messing around with trying to replicate sql server 2000 tables to postgres as well as mySQL. I'm starting with just one table and trying to get that working, it has around 9000 rows, all of which copy to postgres (with some datatype issues).
However, when I try to replicate to a mySQL database however, only the same 152 rows get copied every time.
I compared rows that were copied to ones that were not to see if there was any obvious differences between the two and couldn't find any.
I previously asked What does "Do not replicate DELETE statements" do? to make sure I was correct on my thinking of what "Do not replicate DELETE statements" does. And after finding out it does what I would like it to do, create an archive db, I've tried several testing scenarios to see if it would work. So far I have been unable to not replicate delete statements. I'm not sure if I'm not setting a property right or what and any guidance would be appreciated.
Here is what I've done.
Created a blank db to be used as a subscriber and created a test db with some random data in a table.
Setup a New Publication on the db with the random data as "Transactional Publication"
Selected the following articles and properties in the publication
Tables
DELETE Delivery Format = Do not replicate DELETE statements
Views
Default Values
Stored Procedures
Default Values
User Functions
Default Values
Selected the default options for the rest of the New Publication Wizard steps and clicked finish.
Created a Pull Subscription on the new publication that I just created.
Let it initialize.
Then did a select count(*) query on the test table on the publication (18k+ rows) and subscriber (18k+ rows)
Then did a delete t-sql from the test table on the publication.
Then did a select count(*) query on the test table on the publication (0 rows) and subscriber (0 rows).
Now shouldn't it not delete the records on the subscription db?
Hi,I want to save the last modification date when the row is updated. I have a column called "LastModification" in the table, every time the row is update I want to set the value of this column to the current date. So far all I know is that I need to use a trigger and the GetDate() function, but could any body help me with how to set the value of the column to getdate()? thanks for your help.
View 3 Replies View RelatedHello:
I am running into an issue with RS2k PDF export.
Case: Exporting Report to PDF/Printing/TIFF
Report: Contains 1 table with 19 Columns. 1 column is static, the other 18 are visible at the users descretion. Report when printed/exported to pdf spans 2 pages naturally, 16 on the first page, 3 on the second, and the column widths have been adjusted to provide a perfect page span .
User A elects to hide two of the columns, and show the rest. The report complies and the viewable version is perfect, the excel export is perfect.. the PDF export on the first page causes every fith column, starting with the last column that was hidden to be expanded to take up additional width. On the spanned page, it renders the first column on that page correctly, then there is a white space gap equal to the width of the hidden columns and then the rest of the cells show with the last column expanded to take up the same width that the original 2 columns were going to take up, plus its width.
We have tried several different settings to see if it helps this issue or makes it worse. So far cangrow/canshrink/keep together have made no impact. It is not possible to increase the page size due to limited page size selection availablility for the client. There are far too many combinations of what the user can elect to show or hide to put together different tables to show and hide on the same report to remove this effect.
Any help or suggestion on this issue would be appreciated

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!!!

We have a third party process that runs and updated several SQL tables.
Is there any way to find out what tables are being updated and store it in another table?
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

View 1 Replies View RelatedI 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.

Can anyone offer any alternatives to accomplishing this task? Thanks in advnace for any help you can provide.
