I want to log all changes made to a table (only updates, since there will be no deletes or inserts).
I would like to see the user who changed it, the date and time, fieldname, old value, new value.
If more fields are changed during the update, than add more records into the logging table.
What is best practise to achieve this?
Thanks,
Frans
Hi!I have 6-7 tables total containing subobjects for different objects like phonenumbers and emails for contacts.This meaning i have to do some querys on each detailpage. I will use stored proc for fetching subobjects.My question therefore was: if i could merge subobjects into same tables making me use perhaps 2 querys instead of 4 and thus perhaps doubling the sizeof the tables would this have a possibility of giving me any performance difference whatsoever?As i see pros arefewer querys, and cons are larger tables and i will need another field separating the types of objects in the table.Anyone have insight to this?

I have some data that is updated every day but I don't know when. I'm trying to make a solution that runs a SQL query to check if this data has been updated. If it has, I'll send the updated data with FTP as as text file.
How would you solve this?
My idea is to have 2 SSIS packages.
- Package1: One runs at the same time every day (inserts any missing updates to a table)
- Package2: One runs every hour to check the missing updates table, and runs Package1 if any update for a missing data is found.
My only worries is if Package1 is running and at the same time Package2 decides to run Package1 then I could get into trouble if I'm using temp tables with the same name for the text file updates etc.
Thank you.
I need to load a lot of Excel, CSV, ... etc. files. These files have hundreds of columns and I need to validate the data. Some are simple range type checking, some are more complex checking involve multiple columns.
There may have several hundreds of such rules. And I may need to let the program to automatically correct some invalid data in the future.
Where to implement it in SSIS?
Or just load the files without any checking (all type to text), and checking using T-SQL?
(BTW, I don't have biztalk server).
Thanks in advance.

Hi Folks,
I am about to upgrade my main database server (5 db's - largest 16Gb) from
NT 4 SP 6a / SQL Server 7 SP3 to Windows 2000 SP 2 / SQL Server 2000 SP 2
I am planning to detach the db's, backup to tape a few times and then totally
trash the server, rebuilding it with the new software, restore the db's from
tape and the reattach the db's.
Any reason I should not use this method and can folk advise the best practice
way of achieving this?
Regards
Paul

Hi, hoping I can get a few view on a question I have relating to the above.
I am new to Stored Procedures and Triggers and I am trying to understand 'best practice' a little better. Here is my question: If I have a table that stores information, and when any field in that table is updated (and changes) I would like to inactive the row, prior to change and then add the change by way of a new, active row. This way I can see what it was before and that it's inactive, and what the active value is.
Hope this makes sense, if this is the wrong way to manage change history any suggestions would be appreciated.
A second question I have is as follows: If I have a table that stores a number, based on that number, what would be the best way to create new records in a different table that pulls from the first table. Where the number stored in table 1 represents how many times the record is to be created in the second table.
Thanks. If anyone needs more data, please feel free to ask, I will help as best as I can and appreciate any advice & comments that you can give.

As title, what's the best practise of importing XML data into SQL Server 2005?
I have found this one. http://support.microsoft.com/default.aspx/kb/316005. Is it good enough?
The XML is generated by another system on daily basis. So, the import should be able to handle insert and update cases. How can I do that? Thanks!

View 4 Replies View RelatedI have master tables that I will be updating from our ERP system. Some examples I have seen take an approach of dropping a table in SQL server then creating it again before importing; some, and probably my choice, append and update; I have not seen an example where records are all deleted then the data appended afterwards. Of the three approaches which is generally regarded as best practise / most efficient?
View 1 Replies View RelatedHi,
I work with a large team developing ASP.NET application that has a large database with over 50 complex stored procedures. It is proving more and more difficult and time consuming to centralise the development and update of the database changes and I was wondering if there were any best practises/tools that could be recommended. I have looked on the web for good articles and haven't found anything difinitive (except that Team Foundation Server is the way forward)..
A brief background to the current process is that everyone develops on the same database, and then updates the stored procedure scripts in source safe (manually). Then when we do a new release someone builds a script of all the database updates and runs it. There are issues related to developers updating there stored procedures over other peoples and other concurrency.
I am looking to move all the developers to start using local databases so that there work only effects them, but then this brings up problems of keeping all the local databases up to date whenever they get the latest source code. The only way I currently see is to build a database update program, that will run and update to the latest version.
Surely this must be a common issue? Anyone have any good ideas/concepts?
Also our setup is Visual Studio 2005, SQL Server 2005 and Source Safe 2005.
Cheers,
Andrew Thomas
It seems to me there are two common strategies for doing DB audit trails via a trigger:
1. On an update to a row, duplicate that row in another table with
identical rows, except for perhaps the extra columns which represent
change date and changed by. Eg. When there is an update to the Customer
table, record the changes in Customer_Audit.
2. On an update to a row, check which fields were updated. Then in a
common audit table record the table, row ID, field, previous value and
new value of the field.
I'm wondering about the pros and cons of each. More specifically, do
the pros and cons change if you are using an O/R mapper (I'm using
NHibernate.)
Some thoughts on method 1 . It seems nice for an O/R mapper, since you
could have, say, a CustomerAudit Object inherit from your Customer
object and just add the properties change date and changed by. A
problem with this is you're going to add a whole lot of objects - one
for each object which you want to audit. Another drawback is that it
could be difficult to generate a history for a particular property
which was updated. Let's say I want to see the history of changes to
the customer's status. I have to load a collection of CustomerAudit
objects (which could be costly). Then I have to iterate through them
and compare the status properties to generate a history of statuses.
This is a pretty labor instensive method if you compare it to method 2,
where the change is recorded by field, not row.
Some thoughts on method 2. It's nice since the changes are by field,
not row, which (as above) makes generating a history easy. On the other
hand, you can never have a snapshot of a particular object at a
particular point in time. Moreover, I'm not sure how foreign keys would
be handled elegantly. I record that customer.statusID changes from 3 to
6. I'd have to do a seperate join to the customerstatus table to get
meaning for 3 and 6 (which method 1 would do automatically).
Thoughts? Any preferred way to do this with an O/R mapper?
Thanks

Guys,
We looking to audit tables in the database. In the tables auditing needs to be done only on few columns not all the columns. Is there any 3rd party tool available to do it can it auditing be done on columns only with sql server 2005. Trigger doesnt work in this scenario as it works per row it does not say which column in the row was updated/inserted/deleted.
For example in the below employee table, I want to audit(history) only ssn and dob columns - all the updates/inserts/deletes made to this column should be audited.

Hi folks. I am a new DBA and working on taking over several existing MSSQL 6.5 applications.
My company needs to be able to audit the following actions on MSSQL.
login
logout
insert into specific tables
update in specific tables
delete from specific tables
I am looking for a 3rd party product that provides these services for SQL 6.5. I have found Braintree products and they have really nice auditing but for Oracle and not MSSQL. I have also looking into using triggers to build an audit log for me but the applications we are using require periodic updates that would force me to rebuild the triggers. This may cause too much administrativia.
Any Ideas?
Thanks, Aaron

I need some help with this. I have a development server and all the developers log in as sa. Lately test data has been mysteriously deleted from selected tables. I need to track the time that the activity is taking place so I can figure out who might be playing this little game. Can anyone suggest what I can do to find this out? Your quick response will be appreciated.
Someone had changed the SA password on one of my servers. I need to find out who did this. Can you tell me if there is any historical information kept on any of the system tables that can tell me who (what machine name) and when (date and time)this was done?
Does anyone have a 3rd party or inhouse developed task/procedure to report this kind of security issues?

Hello
I am more of a reporting person, recently I was asked to create stored procedure for an upcoming ASP.NET
application.
We have a problem that we are facing and any suggestion would be very helpfull.
The problem is that we have like 8 differtent tables each with 10 to 15 columns in it.
The front end application has pages with save , update , delete button which are insert,update,delete
for each of the 8 tables
i.e they save , update , delete these 8 tables
They want to a way to Update , this audit table which stores information
like ---
Date
User
Table
Column name
Previous column name
new column name
So for each row that was updated in those 8 tables , each column will have the above fields updated as a row of data
Initially we thought about triggers but it will be like 60 triggers ...Is there a better or other way of handling this?
Any help is appreciated
Thanks

I would like to create a simple trigger on a Customer table to fullfill two fields, on should be filled when a new customer is inserted (DateAdded) and the other when the customer is edited (DateEdited), Yes I know it is quite simple but as I am not a database expert I do not know how to solve this problem.
Thank you in advance.
Hi everyone,
I am to try to find documentation about C2 auditing into SQL Server 2005. The only one doc I fand about it is:
SQL 2000 C2 Admin and User Guide
It cover SQL Server 2000 and Windows NT4.0.
I do not find any document who cover the security from SQL Server 2005.
Can you help me please?
Thx.

Greetings SSIS friends,
Do any of you guys have a link to a website with an example of how to create a solid audit system for SSIS packages?
Thanks for your suggestions in advance.
I am using the SCD Wizard and it is working nicely. Can someone point be to an article/tuorial that would explain how you could create an "audit trail" on the items that may have been changed (type I and II)?
Basically, what I want to be able to do is run a query that tells me what data may have changed. I figured I would have to create an auditkey field in my table which would then link the key to the change detail?
I am trying to write a t-sql query that will work on sql server 2000/2005 that will tell me if auditing is turned on and what it is set to. Have any of you ever come accross a script or SP that can do this?

Hi,
we have database and sql login TESTUSER that all front end application (VB6) user as sql user to be able to communicate with DB. we have around 30+ users machine that is running that front end application.....!
how would i do auditing (who change what data and when, etc, etc) on each user action if needed. for that do i need 30+ unique users for each machine.
Thanks,
Does anyone have a query to determine if auditing is turned on and what it is set to (It needs to be set to failed logins)? Also where the log directory is going? I need the query to work on both SQL Server 2000 and 2005 servers. Any help is appreciated.
