I've got a table that has frequent updates to it. I want 100% change tracking on this table though, so we can rollback to any previous version, or just see any changes people make.
Is there a best practice for things like this? Currently, I'm using a trigger on UPDATE to take the previous values and store them in a history table. This keeps track of who changes what, and when. Plus the most recent data is seperate and more performant to access.
I've also heard about putting an 'IsActive' flag on the main table and any changes that are made just get marked as In-Active and a new record gets added.
How do you track changes to objects in SQL Server. For example changes in stored procedure,views and indexes. What system table or column track or indicate changes in text of sp or views. Help appreciated.
We are building an inventory management system complete with BOM. It is important to track what employee is updating what tables. Currently all such tables have a Date field that is updated when a change is made, and an EmployeeID field which records the employee making the change. I am wondering if someone knows of a better way to track this information. Any suggestions?
OK. For DDL, please refer to the classical Northwind ORDERS table,problem/challenge, find the longest duration (start_date andend_date), during which, no orders were placed.FYI, column names by the order of colid per syscolumns:OrderIDCustomerIDEmployeeIDOrderDateRequiredDateShippedDateShipViaFreightShipNameShipAddressShipCityShipRegionShipPostalCodeShipCountryAny idea/approach? TIA.
Hi I'm trying to get CDC going, it works however when i query the LSN using the functions i get no changes. The min and max LSN returns null. SQL agent is running, db is on full recovery model etc.
Yesterday I had problem with that a sp that contained join that the developer had forgotten the where part. The sp join very large tables and sp took more 95% dual itanium processor. How do fastest track this down when it accrues. Find the sp or sql that running and consume this much processor resources. I tried with a lot. Sp_who, sp_who2, activity monitor.
I wonder if somebody here could recommend a good article about MS Service Broker. I'm looking for some advice and tips in designing applications using SQL Service Broker, mainly QN. For instance, maintenance routines and common faulty scenarios I might find later when my solution is implemented. I have googled for a while but all I can find are recopied examples of QN.
im trying to create a procedure that will insert/update a small table that has an ID, AmtBefore & AmtAfter.
this is just a table that i'd be using to monitor other activity on the database.
i'm really pulling a price + ID every hour and i need to track that somehow and know when the procedure runs if a price is lower than it was the last hour, plus of course keep the ID's straight. does anyone have a good approach to something like this?

I have several transaction tables on which I need to track the changes. That is I need to maitain the history of changes. Only few column values are changed often.
Which is the best way for tracking the changes.
1.Store the whole record after the change ?
Or
2.Store the ColumnName & its respective old & new value ?
Or any other better.
Note : UI part & SP's will take care of the tracking & no plans for triggers.
I have a table in my database and it holds some important information,I want to track the users who are executing DML commands(select,update,delete) on the data in that table. Is there any way do that?If so how could i implement that.can any one help me in this regard? Thanks in advance...
First thank you for all your help thus far. Now I'm stuck again. I've been doing a lot of reading on triggers and logging information into tables but I've been trying to capture how many times someone enters an item into the search box.
So every time somebody types Gumballs into the search box I want to capture it and the name of the person who is currently logged in. Is there away to do this? Maybe this is something that I should be checking in ASP.NET forums?
Hello everyone, I have a fairly unique need :) I am trying todetermine the use/clients for databases in my corporation that I ammaintaining, but that noone seems to know what they are for. Many ofthese databases never seem to have anybody connected to them in thecurrent activity.What I'd like to do is find a way to audit the logins, so everytimesomeone connects to a database it simply logs the clients IP address,what login they used, and maybe what time. I've been searching googlefor this and have found tons of information on auditing the logins,but not the clients, such as by ip. Any help in this regard would beGREATLY appriciated!Joshua
I have a device application that simply needs to upload data to a server. The preferred DB server is Oracle but I've made it work using RDA and SQL Server. The problem I'm having is that it just needs to upload data, whichh I send using the RDA.Push() method. The data arrives just fine, the first time. With every subsequent upload all of the previous data is deleted fromt he server. Apparently RDA is tracking the deletion of the previously uploaded data locally and on the next .Push deleting that data from the server.
My question is: Is it possible to prevent RDA from deleting data on SQL Server? I attempted to delete the rows from the __sysDeletedRows/__sysRowTrack tables but got a "Data is read only" error.
I hoipe someone can point me in the right direction here.
I have an application with the following requirements (using SQL CE 2 alas)
A set of tables on the server that need to be imported to the handheld. Using rda, I need to get the modifications to these tables from the server (add/edit/delete) but the handheld will never update these tables.
A set of tables on the server that need to be imported to the handheld. The handheld needs to add/edit existing records, and it needs to get any changes from the server.
A set of tables on the server where the handheld needs to import a subset of the records. It needs to add (but not edit) new records, upload the new records to the server, and download any changed (add/edit/delete) records to the handheld. What tracking options should I use in these 3 cases?
The problem comes in that I need to have some foreign key relationships in the database on the handheld. Since rda munges the names of primary keys (and indexes), I do not know of a good way to add these foreign key constraints. Any suggestions?
I want to keep track of data change and want to enter the pk such as testkey and timing in different table. is it possible without having to write trigger on the table!!!
Hi, i am trying to find a trigger that is updating a field in one of my tables.
I have a field called [ProfileDate], whenever a member is profiled, this field is populated with a GETDATE() value. I am trying to track down the trigger that updates this field.
I have a bit of a problem I could do with some help with please...
I am updating an old windows client server app that uses ADO 2.8. Slowly but surely I am migrating the code from VB6 to .NET and this now means the ADO code is going to be replaced with ADO.NET.
As it is a client server the application used to establish an ADO connection and hold on to the connection for the entire duration of the app being alive. When a user signed in it would record the user logon code in a database table along with the current @@SPID value.
When the user does something in the application it typically usees an SP to do the database work. Inside the SP it also audits the work being carried out, of course the audit trail records the user id that did the work. The way it determines who called this SP is to query the logon table using the current @@SPID to get the users logon code (remember this was paired up when the user signed in).
This all worked very nicely as only one connection was ever being used and it was always the same connection that was used. However, when I come to use ADO.NET this is no longer valid. I want to use the connection pool and follow the best practices where my connections are always obtained as late as possible and released as soon as possible.
This leave me with the problem of how to get the current users logon code in to the SPs in order for them to continue writing the audit trail. Currently I am thinking that I am going to have to send the users code in to the SP as a parameter, I just wondered if there was an alternative.
Hi I use data presentation controls like gridview, formsview in my application. In many of the webforms i also use multiple datasources mainly for the purpose of 2 way data binding for controls within data presentation controls.I am concerned about the performance issues this might cause as users using these pages increase.What is the likely performance impact ?Once the databind is done and values are populated in the respective controls, does the database connection of datasource control get closed, or is it open?What are the best practices while implementing datasource controls?
I'm looking for some documentation on SQL 2K Installation tips on a Windows 2000 Member Server platform as well as best practices for ongoing maintenance .
Real world experience as well as Microsoft propaganda are all welcome.
I am looking for some examples of how to manage DDL scripts amongvarious versions of a production db and development and testing. Ihave tried a few things in the past, and it always gets very muddledand cumbersome.I need to be able to build any version of the database from scratch,BUT I also need to maintain an upgrade path from any version to anylater version. So it is not enough to just maintain a master buildscript, but I don't want to maintain 2 different things (modify themaster build scripts AND create a new "ALTER" script for each versionchange).I thought I had seen an article somewhere that layed out a process formanaging this, but I can't find it now (I thought it was in SQL ServerMag). Does anybody know of this article or have a resource they couldpoint me to that outlines best practices in this area?Thanks,Jason Wood, DBA in training.
Hi All,My question is what are the best practices for administering largeDBs. (My coworker is the DB administrator. I'm more of thedeveloper. But slowly being sucked in.) My main concern is that wehave some DBs that take approx 3 hrs a night just to rebuild theindexes. I know that with MSSQL 2000, I can use partitioned views tobreak out the table(s) into smaller databases and tables. But we alsohave an older server that runs MSSQL 7. Lastly how do you handledrive space issues? Do you spread out the DB across multiple MDFfiles on different drives? Thanks in advance.
Please forgive me if I have overlooked a thread that answers this question, but I assure you that I have looked.
I would really appreciate a guide of sorts that would tell me the correct steps to take to properly secure a column in my database. I don't need specifics on how to do each step, I either have those already or can find them myself. In fact, I have already successfully encrypted and decrypted some data. I just want to make sure that I create the right keys and certificates and that I follow best-practices as far as backups and stuff is concerned.
Environment is SQL Server 2005 x64 Enterprise running under Windows Server 2003 x64 Enterprise with four processors and 16GB of ram.
I have 28 data copy routines I would like to add to a SSIS package. They use the Data Reader Source to an ODBC database (InterSystems Cache) and copy the table contents to a SQL2005 database for reporting needs. The data rows in these 28 routines range from only 100 rows to over 6 million rows depending on the table. I have tested these individually and they work fine. My question is, is it a good practice to have all of these routines in a single package or can I expect performance degragation?
I am new to SSIS, but done alot of DTS 2000 development.
What is the concensus for developing SSIS packages? Do you just place objects and change the properties of each object, having multiple objects basically doing the same thing, with different properties? Or do you set object's properties and then change properties by code in scripts? Ie Execute SQL, setting connections and SQL Statement by code in a script? Is this even possible? With Microsoft OOP I assume this is possible.
Script> Set properties of ExecuteSQL > set flow to ExecuteSQL.
Is this this only way to do it in SSIS? http://sqljunkies.com/WebLog/ashvinis/archive/2005/06/15/15829.aspx For some reason I figured that SSIS would have this kind of stuff built into it, it seems a function that many would use.
I wonder if anyone knows what would be the best case scenario for the property 'maxinsertcommitsize' for the sql destination task if I want to load 6m records into a target. Is the best setting 0 (try loading all in one batch) or should I choose a different value for example 1000000 per batch?
