How To Get A List Of Uncommited Transactions
Jan 7, 2004
Hi
Our transaction log has grown to a few gigabytes
I suspect one of our server applications had started a transaction
but never commited it.
I cant shrink it since all this size is being used.
I tried checkpointing it but with no effect
Is there some way to get a list of all active transactions and
their start date?
Thanks.

Hi groupI have an application running on a couple of pc's all connecting tothe same SQL-serve databaser. The other day one of my applicationsstarted a transaction which it never committed (programming error) .The application continiued running for a couple og hours filling everyinsert and update statement to the sql-server log-file, where theyremain rigt now. The applications on all the other machinesdeadlocket because they waited for the first application to commit. Ieventually shot down the ms sql service and restarted it. Now all thetransactions which were not commited are not to bee seen in thedatabase, because they remain in the log file (ldf-file) waiting foraf commit I cannot perform. Are there a way to browse an ms-server..ldf file to see which uncommitted records are in itThanks if anyone can heloRegardsjsa

Hi 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

So at the moment, I don't have a function by the name CONCATENATE. What I like to do is to list all those different values that go with a single CASE_ID to appear as a a comma separate list. You might have a better way of doing without even writing a function
So the output would look like :
CASE_ID VARIABLE
=====================
1 [ABC],[HDR],[GHHHHH]
2 [ABCSS],[CCHDR],[XXGHHVVVHHH],[KKKJU],[KLK]
SELECT
preop.Case_ID,
dbo.Concatenate( '[' + CAST(preop.value_text AS VARCHAR) + ']' ) as variable
FROM
dbo.TBL_Preop preop
WHERE
preop.Deleted_CD = 0
GROUP BY
preop.Case_ID

I know I can do a JOIN(parameter, "some seperator") and it will build me a list/string of all the values in the multiselect parameter.
However, I want to do the same thing with all the occurances of a field in my result set (each row being an occurance).
For example say I have a form that is being printed which will pull in all the medications a patient is currently listed as having perscriptions for. I want to return all those values (say 8) and display them on a single line (or wrap onto additional lines as needed).
Something like:
List of current perscriptions: Allegra, Allegra-D, Clariton, Nasalcort, Sudafed, Zantac
How can I accomplish this?
I was playing with the list box, but that only lets me repeat on a new line, I couldn't find any way to get it to repeate side by side (repeat left to right instead of top to bottom). I played with the orientation options, but that really just lets me adjust how multiple columns are displayed as best I can tell.
Could a custom function of some sort be written to take all the values and spit them out one by one into a comma seperated string?

Ok, I want to write a stored procedure / query that says the following:
Code:
If any of the items in list 'A' also appear in list 'B' --return false
If none of the items in list 'A' appear in list 'B' --return true
In pseudo-SQL, I want to write a clause like this
Code:
IF
(SELECT values FROM tableA) IN(SELECT values FROM tableB)
Return False
ELSE
Return True
Unfortunately, it seems I can't do that unless my subquery before the 'IN' statement returns only one value. Needless to say, it returns a number of values.
I may have to achieve this with some kind of logical loop but I don't know how to do that.
Can anyone help?

Hi,
I have a a table that holds a list of words, I am trying to add to the list, however I only want to add new words. But I wish to return from my proc the list of words with ID, whether it is new or old.
Here's a script. the creates the table,indexes, function and the storeproc. call the proc like procStoreAndUpdateTokenList 'word1,word2,word3'
My table is now 500000 rows and growing and I am inserting on average 300 words, some new some old.
performance is a not that great so I'm thinking that my code can be improved.

Hi,
I have set of 2 DTS packages, one of which calls the other by forming a command-line (dtexec) using a Execute Process task.
From the parent package-> Execute Process Task->
dtsexec /F etc... /<pkg variable> = "servername"
Each of the parent and the called package have a variable: "User::DWServerSQLInstance" which is mapped to the SQL server connection manager server name property using an expression. The outer package has the above variable and so does the inner called package (which gets assigned through the command line from the outerpackage call to inner)
I "sometimes" get the following error:
OnError,I4,TESTDOMAdministrator,ACDWAggregation,{A1F8E43F-15F1-4685-8C18-6866AB31E62B},{77B2F3C7-6756-46EB-8C01-D880598FB4B3},5/22/2006 5:10:28 PM,5/22/2006 5:10:28 PM,-1073659822,0x,The variable "User::DWServerSQLInstance" is already on the read list. A variable may only be added once to either the read lock list or the write lock list.
Help would be appreciated!
I have seen other posts on this but, not able to relate the solution to my scenario.

Hi All,
I have seen a few other people have this error.
Package works fine when run from BIDS, DTExec, dtexecui. When I schedule it, It get these random errors. (See below)
The main culprit is a variable called "RecordsetFileDIR" which is set using an expression. (@[User::_ROOT] + "RecordSets\")
A number of other variables use this as part of their expression and as they all fail, pretty much everything dies.
I have installed SP1 (Not Beta) on server. Package uses config files to set the value of _ROOT.
The error does not always seem to be with this particular variable though. Always a variable that uses an expression but errors are random. Also, It will run 3 out of 10 times without a problem. I am the only person on the server at the time.
Any ideas?
Cheers,
Crispin

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?

Hi 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

Hi 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

Is 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?

I 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.

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'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?

Hi 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 ?

Hi,
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.

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.

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

I have a class that use a TransactionScope object for make make two operations into a database. The problem is that in a computer works well but in another I receive a error message: "MSDTC is not running in .SQLEXPRESS". I had watched the services in the computer and the "Microsoft Distributed Transaction Coordinator" is running.
Does somebody know what is happening?
Thankyou and sorry for my English.

I am using ADO.Net for data access and was wondering if anyone knows a good resource for information of sql transactions? Also, do you know if the ForEach statement can be made in sql transactions?
