Log Database Transactions
Nov 21, 2007I would like to have a log where I can see who all updated a particular database table and when.
Is there any such logging facility provided by MS SQL Server?
Thanks,

Changing Connection Transactions To Database Transactions
May 22, 2005Hi there,
I have decided to move all my transaction handling from asp.net to stored procedures in a SQL Server 2000 database. I know the database is capable of rolling back the transactions just like myTransaction.Rollback() in asp.net. But what about exceptions? In asp.net, I am used to doing the following:
<code>Try 'execute commands myTransaction.Commit()Catch ex As Exception Response.Write(ex.Message) myTransaction.Rollback()End Try</code>Will the database inform me of any exceptions (and their messages)? Do I need to put anything explicit in my stored procedure other than rollback transaction?
Any help is greatly appreciated

Nested Database Transactions In Forms
Sep 19, 2007This should be a fairly simple question. It's based on this error message:"Transaction count after EXECUTE
indicates that a COMMIT or ROLLBACK TRANSACTION statement is missing.
Previous count = 1, current count = 0." I get this when executing a stored procedure upon processing a form. This error happens when I intentionally provide input to the stored procedure that I know should cause it to error out. I catch the exception, and it contains the error message, but it also contains the above message added on to it, which I don't want. I won't post the entire stored procedure. But I'll list a digest of it (Just those lines that are significant). Assume that what's included is what happens when I provide bad input:BEGINBEGIN TRYBEGIN TRANSACTION RAISERROR('The item selected does not exist in the database.', 16, 1); COMMIT -- This won't execute when the RAISERROR breaks out to the CATCH block END TRY BEGIN CATCHROLLBACKDECLARE @ErrorSeverity INT, @ErrorMessage NVARCHAR(4000)SET @ErrorSeverity = ERROR_SEVERITY()SET @ErrorMessage = ERROR_MESSAGE() RAISERROR(@ErrorMessage, @ErrorSeverity, 1) END CATCH END Okay, so that works fine. The problem is when I execute this with an SqlCommand object, on which I've opened a transaction. I won't include the entire setup of the data (with the parameters, since those seem fine), but I'll give my code that opens the connection and executes the query: con.Open(); SqlTransaction transaction = con.BeginTransaction(); command.Transaction = transaction; try { command.ExecuteNonQuery(); transaction.Commit(); } catch (Exception ex) { transaction.Rollback(); } finally { con.Close(); } I'm calling the stored procedure listed above (which has its own transaction), using a SqlCommand object on which I've opened a transaction. When there is no error it works fine. But when I give the stored procedure bad data, it gives me that message about the transaction count. Is there something I need to do in either my SQL or my C# to handle this? The entire message found in the Exception's Message is a concatenation of the message in my RAISERROR, along with the transaction count message I quoted at the beginning. Thanks, -Dan
Using Transactions Causes Database Connection To Fail
Feb 8, 2006In one of my packages, I set the package-level property called TransactionOption=Required. During run-time I saw an error saying "[Execute SQL Task] Error: Failed to acquire connection "SQL_DW". Connection may not be configured correctly or you may not have the right permissions on this connection. ". When the property is changed to anything other than Required, it works fine (the calling package that calls this package is not involved in a transaction).
The machine running the packages is Windows Server 2003, and so is the database where the data lives. I verified that the machine containing the database does has Enable Network DTC Access checked in Control Panel -> Add/Remove Windows Components -> Application Server.
Is anyone else having this problem?
Sql 2005 Database Contains Deferrd Transactions
Nov 13, 2007Help, I had a tran log grow to it's restricted size, however the person that created this made the max size almost equal to the set max size. Needless to say I have not space to work with. SQL got bounced and my db went into recovery mode. After recovery mode was complete I tried to put my database in emergency mode but it exec's but never sets the mode. Next I tried to dbcc checkdb and I get msg 7929, level 16 state 1, line i Check statement aborted. Database contains deferred transactions. There is no back up for this database. Dev play area. I can not detatch db becase of the same error. What next? Any help would be great.
View 7 Replies View RelatedPostback Causing Database Transactions To Replay
Dec 7, 2006Hey,
I hope someone can quickly tell me what I am obviously missing for this weird problem.
To give a general picture, I have an ASP.net webpage that allows users to select values from several dropdown menus and click an add button which formats and concatenates the items together into a listbox. After the listbox has been populated the users have the option to save the items via a save button.
The save button parses each item in the listbox to basically de-code the concantenated values and subsequently inserts them into a table residing on a backend MSSQL 2005 database.
PROBLEM:
In the process of testing the application, I noted this strange behavior. If I use the webpage to insert the values, go to the table where the values are stored and delete the rows; Upon a refresh of the web page the same actions seem to be getting replayed and the items are again inserted into the table.
Naturally, what I'd really like would be for the page to refresh and show that the items aren't any longer there and not the other way around.
If the code that performed the insert was residing in a component that was set for postback I'd expect this type of behavior but its in the Save buttons on_click event. I have tried practically everything in effort of targeting the problem but not having much luck with it.
Is this behavior practical and expected in ASP.net or has anyone ever heard of anything similar? I have never encountered this type of problem before and was hoping someone could provide some clues for resolving it. If more information is required I'd be happy to supply it. Hopefully, there's a simple explanation that I am simply unaware since I haven't experienced anything like this before.
Anybody got any ideas???
Thanks.
Finding Out Database Usage (number Of Transactions)
Nov 20, 2003Hey,
Is there somewhere in MSDE (or SQL) where you can see how many transaction are made to a sertain database or by a sertain user? At this way i could figure out witch database/user uses most (or least) recources (cpu) over a period of time.
T-SQL (SS2K8) :: Database Triggers To Prevent Large DDL Transactions?
Mar 2, 2014A server I'm working on has a very unique situation, where user tables and production tables reside on the same database. Users update / create tables or populates these tables, so it can't be a table-specific trigger. However, they give a new meaning to "kamikaze pilots" as it's not uncommon for them to "accidentally" update / insert / delete 500,000,000 + records in a single statement. I've tried educating them to use batching, but to no avail, so now I'm forced to stop these statements BEFORE they execute, based on rowcount, as they fill up the database log so quickly that it goes into recovery mode (It has a 200GB log file - insane, I know).
I recon the mosts transactions allowed should be 1,000,000 records in a single statement. Looking for database trigger to stop them from executing statements with large records?
Transact SQL :: Replicating / Synching Data Between Two Tables On Same Database With Live Transactions
Oct 7, 2015Client is running X- version of application and corresponding database size is huge. Now client's vendor is releasing Y-version of same application with many database schema changes (like new tables added, new columns added, renamed existing columns and etc) To upgrade to the Y-version, vendor is suggesting to my client that down the system and do the upgrade for application/database to Y-version. We are sure that this process will take days together to upgrade to the Y-version. My client is not ready to down the system for that long. So we are trying to find the solution with minimal down time.The approach we are thinking is,Â
1) Create the replicated database to another server (server2) from production server(server1) using golden gate with X-version
2) Create new tables/schema updated tables from Y-version database on same server1. Here for  Updated schema tables we are planning to use the name <table_name_Y_version> as the same table name exists in X-version.
3)With above 2 steps, golden gate replicate the changes from production to server1 and server1 will have the new Y-version table schema (with different concatenate name ' _Y_version'). BTW , there is no affect for the production
4) At this stage we are planning to find best approach, to fill the '<table_name>_Y_version' from X-version tables. two challenges here a) all data needs to be moved to Y-version tables b) they have to sync data in real time.
we thought of going to
a) ssis package to pump the data to Y-version tables, but real time data will not sync.
b) trigger based technique, previous experience said, lot of load
c) thinking about sql replication.
Can CREATE DATABASE Or CREATE TABLE Be Wrapped In Transactions?
Jul 20, 2005I have some code that dynamically creates a database (name is @FullName) andthen creates a table within that database. Is it possible to wrap thesethings into a transaction such that if any one of the following fails, thedatabase "creation" is rolledback. Otherwise, I would try deleting on errordetection, but it could get messy.IF @Error = 0BEGINSET @ExecString = 'CREATE DATABASE ' + @FullNameEXEC sp_executesql @ExecStringSET @Error = @@ErrorENDIF @Error = 0BEGINSET @ExecString = 'CREATE TABLE ' + @FullName + '.[dbo].[Image] ( [ID][int] IDENTITY (1, 1) NOT NULL, [Blob] [image] NULL , [DateAdded] [datetime]NULL ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]'EXEC sp_executesql @ExecStringSET @Error = @@ErrorENDIF @Error = 0BEGINSET @ExecString = 'ALTER TABLE ' + @FullName + '.[dbo].[Image] WITHNOCHECK ADD CONSTRAINT [PK_Image] PRIMARY KEY CLUSTERED ( [ID] ) ON[PRIMARY]'EXEC sp_executesql @ExecStringSET @Error = @@ErrorEND

Can anybody suggest me a website where I can find articles on Managing transactions with Sql server. Also a scenario where the transactions take place in a environment involving 2 different databases, Like the bank account and credit card transactions (specifically of 2 way kind)
Thanks

Apr 6, 2005I have a web application with a shopping cart, how do I stop all the shopping cart transaction from going into the db log? Is this possible? These are are only transient data movements, and will never be need to to restore to, and they are cause log bloat. Or is there a better way to stop log bloat?

TRANSACTIONS IN DTS
Apr 17, 2000Hi All,
How can we change connection properties in a DTS pkg with connection?
You can loop through the connection count but the connection ID is not static one.So can’t rely on that.
Is there another way of changing connection properties?
Thanks in Advance

Help With DTS Transactions
Sep 5, 2000Hi all....
I am currently designing a DTS Package to import data that is processed daily into a large database.
I have to design the package such that if any step fails when importing, I roll back the entire transaction.
I have designed the package with this in mind, checked "join transaction if present" and "rollback transaction on failure" in all of the workflows. I have also made all workflows serialized.
However, when I run the package, it fails on one of the data pumps with the error:
Transaction context in use by another session.
Any ideas?
Thank you,
Brian

Sep 6, 2004Is there a point to wrapping a single UPDATE or INSERT statement in an explicit TRANSACTION:
BEGIN TRANSACTION
INSERT INTO Table (...) VALUES (...)
COMMIT TRANSACTION
I understand ACID and concept of transactions. However, I thought they were only necessary for multi-statement operations. I'm maintaining code that does this and am wondering if this is necessary. Does SQL Server guarantee ACID for single statements? Are single UPDATE/INSERT statements prone to race condition like affects without using explicit transactions?

Transactions/Sec
Jul 1, 2007I have a table with around 240 columns and one of the column in the Table is the Inserttime ( DATETIME ) and I using a GETDATE() function in the stored Proc, when we insert data into the table. In the same Milli second 2007-06-27 09:32:58.303 , I have around 7600 records in the database. The Stored Proc is called for each Individual record and we don't bunch the transactions. Is this possible.
I did some bench marking on this server and I can insert only 700 - 800 records approx / sec on this particular table.
Thanks

Oct 8, 2007I am working with transactions and use try catch to capture errors and in the event of an error i have to rollback the transaction. How can i perform this?, most of the errors which i forsee are either insertion of null values into non nullable columns or violation of Primary keys while inserting duplicates.
I started by coding the following way but it does not rollaback apparently the try catch does not work for above kind of errors..Can somebody help..

When i am working with Transactions i got one doubt.
If i am inserting any records into a table with primary key if a transaction is rolled back i am finding one primary ID is missing. Is it so.
Transactions
Apr 2, 2007I've been searching around and haven't found anything that simply states what I want to know.
I want to use a transaction within my CLR Stored Proc, to do so I've got System.Transactions referenced and I can access the current transaction via Transaction.Current.
My questions are
Will there always be a current transaction?
Do I need to create a new transaction if one doesn't already exist?
Transactions In SQL CE 2.0 And CF1.1
Sep 4, 2006Hi world:
I have this issue:
I need to push rows from CE to SQL Server 2000 and after delete these rows of CE database only if all rows have been sent to SQL Server 2000.
I think the best is work with transactions. Since I know I can use transactions for this purpose, can anybody give me a link with push transaction examples ?

Using Transactions
Mar 31, 2008Hi,
I am using C#.NET 2005, SQL Server 2000.
I have a few questions to ask. Firstly, can anybody help me by telling the difference between the code below and the same code with comments removed:
string localquery = "select bla bla"; SqlDataAdapter _sda; DataTable _dt; SqlCommand _cmd; bool isErrCatched = false; Exception ExcToThrow = new Exception(); using (SqlConnection _cn = NewConnection) // NewConnection returns a static SQLConnection object { _cn.Open(); _cmd = new SqlCommand(localquery, _cn); //SqlTransaction myTrans; //myTrans = _cn.BeginTransaction(); //_cmd.Transaction = myTrans; _dt = new DataTable(); _sda = new SqlDataAdapter(_cmd); try { _sda.Fill(_dt); _sda.Dispose(); //myTrans.Commit(); } catch (Exception exc) { //try { myTrans.Rollback(); } catch {} isErrCatched = true; ExcToThrow = exc; } finally { _cn.Close(); } _cmd.Dispose(); } _cmd = null; if (isErrCatched) throw ExcToThrow; return _dt;
My first question: Can there be a performance loss if I uncomment the lines about transaction usage? I mean, when I do this I start to get more timeouts.
My problem goes on. When I comment those lines and run a stress tool, I am getting "column X does not belong to table Y" errors. If those lines are not commented i am not getting this error, but I get timeout errors frequently. So, my second question: is there something wrong in my query or is there a bad coding practice I am following? Could someone offer a better and more robust sample for this code block?
By the way, connection pooling is on. And these errors are observed under high loads.
Thanks everybody.
Transactions
Jun 7, 2006I have transaction that will run on an hourly bases. I need to make sure that no one will start this transaction while it is running. I just need to know the system table that has all the transaction names in them and check to see if the transaction is running or not. what i am trying to do is not to have locks....just wanting to make sure that no one would run the same transaction twice. does anyone have any idea on how we can do this?

If you ask a .net developer he would likely say that he uses System.Transactions to manage transactions, a DBA on the other hand places transactions within the T-SQL of stored procedures.
What rules do architects and others, use when determining if the transactions should be placed in:
.net Middle Tier Components using System.Transactions for example.
T-SQL Stored Procedures.
Both .net Middle Tier Components and T-SQL Stored Procedures.

Transactions And Exceptions
Nov 1, 2006if i have a loop that runs through records in a dataset like thisfor(int i=0;i<ds.Tables[0].Rows.Count;++i) and in this loop i have several sql commands that run as a transaction in a try / catch block like : try{ // do stuff}catch{ trans.RollBack();}how can i keep the loop going even if a transaction failed. So the transaction works for each individual row. if row 100 fails for whatever i would like the loop to continue running, do i just simply remove the "throw" and it will continue looping ? my catch block currently looks like catch(Exception ex){transaction.Rollback();activity.Log("Transaction aborted, rolling back. Error Message: " + ex.Message + " Stack Trace: " + ex.StackTrace.ToString());throw; }thanks,mcm
