I need to track all changes to my database at the application level. Say if anybody logs into the application with his user id and password, any add,delete,update should be tracked. This is an application with 5000 transactions a day. I thought of using a trigger on all the tables to capture the following fields.
[UserID]
[AuditDate]
[TableName]
[PrimaryKey]
[Action]
,PreviousValue]
[CurrentValue]
I thought of adding all the application user as a database user. So then userID will be SYSTEM_USER , and AuditDate will be GETDATE(). Is this a good idea?
I dono whether the field primarykey is really essential in my audit table? Please advice.
The field 'Action' will be update/delete/insert. Previous and Current value will be the entire record from the temp tables inserted and deleted in triggers. I dono whether this is a good idea to store the entire record or just the field which was changed or updated(as updates r gonna be more than insert and delete), and the entire record for insert and delete. Is that possible? We have columns_updated() in sql server 2005 where we can we find the columns which was updated. Will that work?
Can i capture all actions(inser/update/delete) in a trigger with FOR INSERT,UPDATE,DELETE ? If so, how can i update "ACTION" and implement something different for update(as discussed earlier) . Is there any other field which you think i should capture which might be important as a part of auditing or tracking.
Can we use trigger for all tables in the database at one time?
I know there are too many questions . I wud greatly appreciate any thoughts or help for any portion of it.
I have made a server security audit and specify from database audit specification to audit "select" on a certain user and on a certain table. I logged in by this user and made the select statement..when i run this query
"select * from sys.fn_get_audit_file('d:Auditaudit1*',null,null)"
It return a value at which time the query has done
after 15 minutes i repeated the same action, i run the audit query and the same result is showed off on the panel.is it suppose to return a list of values by how many times this user has made the select statement on that table ? for example at 5:00 pm then 6:00 pm and so on
Hi all, please help. I m trying to create an "empty" table from existing table for the audit trigger purpose. For now, i am trying to create an empty audit table for every table in a database named "pubs", and it's seem won't work. Please advise.. Thanks in advance.

I write a insert trigger on my table LeaveRegister(1000 rows) and inserting rows in audit table, but when i inserting a row in LeaveRegister table. In audit table 1000 + 1 rows are inserting every time.
Hallo i have two tables, MainTable and MainTableAudit: the second one keeps DML auditing via triggers. I'm trying to build a query to highlight changes occurred to fields between the MainTable record and its audited records in MainTableAudit, for example, let's suppose i entered an item with some wrong attributes, and edited it three times: MainTable record contains the latest and current version ID002|Hitchhikers Guide to the Galaxy|Sci-fi|240 pages MainTableAudit contains edited ID002 versions ID002|Hitchhikers Guide to the Galaxy|Sci-fi|232 pages|2006-07-08 08:32:12 ID002|Hitchhikers Guide to the Galaxy|Sci-fi|212 pages|2006-05-08 10:54:02 ID002|Hitchhikers Guide to Galaxy|Sci-fi|222 pages|2006-07-04 11:42:16
I would like to build a report like this: first insertion: Hitchhikers Guide to Galaxy|Sci-fi|222 pages modified on 2006-07-04 11:42:16: field "Title" changed from "Hitchhikers Guide to Galaxy" to "Hitchhikers Guide to the Galaxy", field "PageNo" changed from "222" to "212" modified on 2006-05-08 10:54:02: field "PageNo" changed from "212" to "232" modified on 2006-07-08 08:32:12: field "PageNo" changed from "232" to "240" current version: Hitchhikers Guide to the Galaxy|Sci-fi|240 pages
i'd prefer to use T-SQL and keep all into a single place (a view or storedprocedure), or at least to use reporting services; btw i would like to avoid coding web pages or hosted applications.
I need help...here is the problem.Last weekend, the servers in our datacenter where moved around. After thismove, and maybe coincidental, 1 server is performing very poor. Afterrunning a trace with SQL Profiler, I saw the problem which was laterconfirmed with another tool for SQL server performance monitoring. It seemsthat all connections to the SQL server (between 200 - 400) are doing a login/ logout for each command that they process. For example, the user'sconnection will login, perform a SELECT, and then logout. This is not a..NET application. The client software was not changed, it is still thesame. The vendor has said that it is not supposed to do that, it issupposed to use 1 connection that log's on in the morning and logs off atthe end of the day or whenever the user exits. 1 user may have severalconnections to the database.At times, the server is processing over 250 login / logouts (avgeraged for30 second period). Has anyone seen this problem? I have the server inAUDIT FAILUREs only. The server has become very unresponsive, things thattook 3 seconds now take over 15 seconds.Any ideas???
I need to be able to audit the command Insert - Update - Delete sent to a table. I have attempted with a trigger but I have not been able to obtain the fields that have been upgraded.
It is possible to generate in the trigger the command Update - Insert - Delete sent?
Can anyone help, I am able to create a trigger that will populate a audit table everytime one of my tables columns data changes, but I have an applications from another user that has a stored proceudre and when that is called from an application it hit the original table twice, so the audit table will get a duplicate entry.

I'm trying to create and Audit report for different tables.I'd like to use an generic table structure for the report which will be temp.I was thinking something like this:
I've already created the audit table with same structure plus all field duplicated and action type. (this was a request)Now I need to group it for the report.following an example of audit table I've created
tblTest_audit ( ID ID_new Name Name_new Address Address_new )
We would like to create a audit table for storing information if anyobjects like tables / stored procedures are dropped.Table would also contain information about time and the user name whohas dropped the object.Any help would be great.Thanks in advance.Kamal
Does anyone know of a quick way to audit all users in a database and display their rights and permissions on a table level. I would hate to have to do it one user at a time. There has to be an easier way.
I'm going through a Sarbanes Oxley audit and need to provide them this information.
1. It looks like a 'ª' delimiters between fields. I need to pull out the second column in the above example it is - 9999999999. This is the place reference, so I need that in a separate field. 2. I need a way to compare the two fields and report back the change. So in the above example shows EAST. The After image shows WEST - I need the before image of EAST in one column and the WEST in another column.
The following is the trigger which create a row in the audit table when a single deletion is occurred.
ALTER TRIGGER [dbo].[TRG_Delete_tbl_attendance] ON [dbo].[tbl_attendance] AFTER DELETE AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements.
[code]....
I am trying to create a trigger which should prevent the bulk deletion. The following is the trigger which I have written, it is preventing the bulk deletion. But the problem is, it is removing the single deletion entries in the audit table. I want audit table to hold back the single deletion entries without allowing the bult deletion

Currently running Sql Server 2005Is it possible to issue the delete command and capture the affected rows asxml types that will be stored in an audit table with an xml column?Something along the lines of:delete from source_tableoutput(deleted.*into audit_table (xml_audit_column)for xml auto)where source_table.column = @delete_value
I am looking to track any changes made to any table within a db into a single audit table which will hold as fields: the table that has been updated/inserted, the field that was changed, its primary key, the old value and the new value specific to that field, and the date it was updated/inserted.
From what I have read, it does not look like this is possible with a trigger on table as it is not row specific and that I might have to control this from the business layer (vb.net). I am correct in this assumption, or is there a way of tracking specific data changes through triggers.
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
This Audit Trigger is Generic (i.e. non-"Table Specific") attach it to any tabel and it should work. Be sure and create the 'Audit' table first though.

The trick was getting the Table Name and the Primary Key Columns. I hope this code is found useful.
I want to register into a table each time a user creates, modifies or deletes any object in a database. It's not possible to add a trigger to the sysobjects table. What can I do?
I enabled the C2 Audit option for my SQL server and it is working allright. i am trying to figure out how can i configure the audit to run for specific databases/tables only. I have several databases on the server but I just want to audit one table in one database for PCI compliance rules. Any recommendations?
Good morning, Im having a little problem with this report I need to generate, so I thought I would ask for some advice. I have 2 tables. The 1st is the actual table and the 2nd is the log table (Employee; Employee_log). the '_log' table is an image of the Employee table except it has 4 extra fields (recID, last_updated_employee_id, operation and operation_date) recid being the PK of the log table. I need to generate a report that contains some thing like the following:
Table_Name
Column_Name
Old_Value
New_Value
Employee_Modifier
Operation
Operation_Date
Employee
LastName
Reid
Blevins
Jessica Bluff
UPDATE
2/2/2008
Employee
FirstName
Bison
Blison
Jessica Bluff
UPDATE
2/1/2008
Employee
EmployeeID
1234
Jessica Bluff
INSERT
2/1/2008
Employee
EmployeeID
75
Bill Thompson
DELETE
1/28/2008
To do this, I compare the Employee table to the Employee_log table. If I find changes (the two columns do not equal), I add that columnName and the column value for the regular table(new_value) and the column value for the log table(old value). If anyone has a solution or some sql to help me out, it would be greatly appreciated. (A query that will give me each columnName with the value per row would help; Somehow possibly joining my Employee table with 'INFORMATION_SCHEMA.COLUMNS' ??) Thanks!
I wish to track changes made to a table, including login who made the change, time of change, etc, without having to change the existing table structure, stored procedures, application. If anyone has any strategies (with a brief explanation) or articles they could point me to, it would be very much appreciated.
My thinking is to set up a trigger to write both old and new data to a audit table but considering different strategies may be helpful.
I have tried to make my basic audit log do more, but i haven't gotten very far;
In my basic audit log, i record this information:
table type of change field modified old value new value db user date/time
This audit records everything, which is great, but it cannot relate information when i go back to analyze the changes; for example, when a "directory" record is added, a user's information may be entered into several different tables, such as:
name (different table) addresses (different table) phone numbers (different table)
If one wanted to look up the changes to addresses of a person in the directory based on the person's name, i could not do it with my existing audit log because the addresses would be in a different table than the name table and there is no relating data in the audit log to relate the address changes to a persons name;
What might be a solution? I have tried a few approaches and am at a loss;
does anyone know how i can audit a servers login id's and tell the last time it was used. i have just gain about 8 sql servers with a bunch of users that i know are no longer around. so i am trying to trim out dead id's
I am currently developing a system which uses SQL Server 7 as its repositry. One of the systems requirements is the ability to be able to record any changes made to the data, and by whom. In other words I need to store the before and after with a userid.
Is there away to track which user had deleted and object(table), the transaction log has that information but you can't read it and the error log doesn't log such info. Any advice would be appricated, thanks.
