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?
View 3 RepliesHi 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
Hi,I am currently having dificulties in finding a way to use transactions while using classes for table representation.Let me explain, i have two tables a Customers and a Movements one, so two tables = two classes. Each class supports Insert, Edit and Delete, so if this tables worked seperatly there would be no problem but in this case whenever i create a customer i must create a movement for that customer so the connection don't pass between classes and i cannot use transactions ;(Is there any brilliant way to use transactions any other way? Even between connections or getting a solution for my implementation?Best Regards,Luis Simões

View 1 Replies View RelatedHello guys!
I am working with SQL Server 2005 a few months, and i need your help about transactions topic.
In first, i hope you are patient with my english, i will try to explain it the best i can ;-)) and now... my question and thanks you in advance.
I am trying to set the transaction option of a foreach loop container task in run time using the Expressions option. There, I have configured the transaction option of this task with a variable value (var type int) and this variable is informed at the beginning of my dts using a script task (values: 0 for Not Supported, 1 for Supported, 2 for Required).
The problem is the transaction option gets the variable value but... the variable value by default. After, during the dts execution, the variable gets the new value but not the transaction option.
In summary, my question is ... is it possible to set the transaction option during the run time?.
Thanks for your help!

I have a requirements to collect Transactions per second on 50 databases from a sql server instances.provide me a script to collect TPS for 50 databases?
View 8 Replies View RelatedI have a million plus line program that uses DAO and JET/Access databases. We are modifying the code so that it will work with BOTH JET and SQL Server databases with an eye to moving to just SQL Server eventually.
Much of the code works just fine without change when using DAO and SQL server as 90+ percent of the code is accessing data READ-ONLY. (Jet's ODBC capability is used)
There are however some transactions that will not work.
When I examine the SQL Trace, I notice that after the transaction has begun, the SPID has changed. This happens often when cursors are used, BUT happens even if the only activity after a DBEngine.BeginTrans is issued DO NOT USE CURSORS as in the following code:
DBEngine.BeginTrans
strSQL = "INSERT INTO [TestTable] (MyKey,MyData, MyData2) VALUES (1,'apple','fruit')"
DB1.Execute strSQL
strSQL = "UPDATE [TestTable] SET [MyData] = 'apple2' WHERE [MyKey] = 1"
DB1.Execute strSQL
DBEngine.Committrans
The second DB1.Execute times out: [Microsoft][ODBC SQL Server Driver]Timeout expired
The trace shows a new SPID is opened when the UPDATE query is executed. A new SPID is spawned and the JET engine is sending an SELECT SQL to get the value for the MyKey:
SELECT "dbo"."TestTable"."MyKey" FROM "dbo"."TestTable" WHERE ("MyKey" = 1 )
The second SQL statement is waiting for the first one that is being done in a transaction to be completed. The program is expecting that both of these will be being done on the SAME SPID or at least the same transaction scope.
So, since I have no way of knowing how and when a new SPID will be spawned using DAO, we are not going to use it for when we do transactions.
I have tried to use ADO (Provider=SQLOLEDB.1), but ADO has the same problems as DAO as far as a new SPID being spawned in some circumstances, but it works in more situations than DAO.
The Connection Object is not guaranteed to be attached to a specific SPID - it can change at will. So Cn.Execute done twice in succession may be done on separate SPIDs.
My question is this: Is there a way to make sure that no new SPID is spawned?, Is there a way to know when a new SPID will be spawned so we can know how to avoid this situation? Is there a better way than using ADO? Keep in mind that this program has to be able to use BOTH Access/Jet databases and SQL server.
Note:
I have spent over 160 hours reading about Jet, the VB Guide to SQL Server, searching MSDN, Google etc. No article really does justice to this subject of transactions using DAO, ADO and SQL Server and the issue of the SPIDs (equivalent to a session and the session is the scope of the transaction). If you could be sure to stay on the same SPID, then you could just issue your own SQL Begin Transaction and control it all if you only plan on doing SQL statements without the need for cursors. A Microsoft article on this subject would be really helpful to all the programmers that are just now getting around to migrating to SQL Server.
Also, note, that if we did not do transactions, then we would not have to modify a single line of our code to make it work with SQL Server.
There is virtually no documentation for much of what I have written about in this Thread. I am very surprised as it seems this would have come up for thousands of programmers. I must be missing something, so thank you in advance for your help.

Hi
I have a couple of sql servers registered in EM which are outside of the domain. Whenever I run queries on them with the query analyzer, they seem not to commit the transaction. When I'm about to close down the window, I'm always told that there are uncomitted transactions.
Is this some kind of a bug, and is there something I can do about it?
Thanks

Hi all,
When i begin a distributed transaction..., do i need to always
set xact_abort on?
But when i tried to put custom error handling to roll back a transaction with a linked server , it seems its impossible (as set xact_abort on, already automatically rolls back the transaction)
Does anyone have any ideas on this?
Thanks in advance

Hi,
I've tried to enclose a few database operations in a TransactionScope block but it looks like SQL Server CE RM does ignores ambiental transaction.
Here is the code:
static void TestTxn() {
// Command to insert an integer in a table with a single integer column
string cmdPassText = "INSERT TESTTABLE (INTFIELD) VALUES(1)";
// Command to force field type mismatch exception
string cmdFailText = "INSERT TESTTABLE (INTFIELD) VALUES('Foo')";
using (TransactionScope scope = new TransactionScope()) {
using (SqlCeConnection conn = new SqlCeConnection("DataSource = 'Test.sdf'")) {
try {
conn.Open();
SqlCeCommand cmdPass = new SqlCeCommand(cmdPassText, conn);
returnValue = cmdPass.ExecuteNonQuery();
SqlCeCommand cmdFail = new SqlCeCommand(cmdFailText, conn);
returnValue = cmdFail.ExecuteNonQuery();
}
catch (Exception ex){
Console.WriteLine("Command failed");
Console.WriteLine("Exception Message: {0}", ex.Message);
}
}
scope.Complete();
}
}
After first command suceeds and seccond command failes table still has one affected row after transaction.
Am I doing something wrong or System.Transactions.Transaction is not supported with SQL Server CE RM?
Thanks,
Aleksandar
I have a SQL Server 2005 with a linked server to an Oracle RDB 6.0, using the Microsoft OLE DB for ODBC provider. I would like to select some rows from the Oracle RDB and then Update those specific rows afterwards. Whenever I try to do this in a transaction (BEGIN TRAN) I get an error "Driver not capable". Is there any way to do this in a single transaction?

View 1 Replies View RelatedI'm trying to create a transaction replication from SQL Server 2000 to 2005. Basic replication between the servers works just fine. However, what I want to accomplish is to be able to skip some of the transactions. Example - from time to time we want to purge some of the historical data from the main database (the publisher). We don't want the same purging to occur on the destination database, which will be used for reporting purposes and needs to include all the historical information. I wanted to simply stop the replication log reader, purge the records, backup the transaction log with truncation and then restart the reader. The only problem - the truncation on the replicated database keeps the transactions of the purging until they are replicated, so the transaction log backup doesn't help. Any ideas would be greatly appreciated!
View 5 Replies View RelatedHi All,
I am writing an interface between SQL Server and Access. I have chosen to use a linked server using the Microsoft.Jet.OLEDB.4.0 provider. One of the requirements is to have multiple SQL statements in one transaction, which is where I am encountering the problem. (see below)
BEGIN TRAN
INSERT INTO ACCES...Table
Msg 7390, Level 16, State 2, Line 2
The requested operation could not be performed because OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "HES" does not support the required transaction interface.
I am having a really really hard time finding documentation on the Microsoft.Jet.OLEDB.4.0 provider, specifically I want to know for sure if it supports the ITransactionJoin interface.
The main question is - does MS Access linked servers support transactions?
Thank you for your help,
I have exausted all resources available to me in finding out the answer.
Thanks,

May i have a list of Which queries or codes couldn't use in a Transactions in Sql Server ?
I have a piece of code that has happily run daily for at least 4 years. I have moved it to a machine that is meant to have an identical set-up, and it fails. I need to work out why it fails, but I am stuck. The code works as follows:
CREATE storedProc1 (Parameter1, etc)
DECLARE @TransactionName nvarchar(127), @TransactionActive bit
-- Plus Other Variables...
BEGIN
BEGIN TRY
SET @TransactionName= 'TransactionName1'
SET @TransactionActive = 'True'
BEGIN TRANSACTION @TransactionName WITH MARK
[Code] .....
When I EXECute StoredProc1, it fails with the Error Message "Cannot roll back . No transaction or savepoint of that name was found." I think that message comes from a ROLLBACK TRANSACTION statement in the CATCH of StoredProc2. I have tried commenting out that ROLLBACK statement, which changes the error message to: "Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 1, current count = 2."
I need to live update my SQL-Server 2000 database from AS400 database.
I usually use Access 2002 database between the AS400 database and the SQL-Server 2000 database to reflect any live update.
I use the (Link Tables...) option when creating a new table in access and link it with the ODBC to connect with the AS400 database.
After that I work with the Access link table.
Is there any tool in SQL-Server 2000 to show the live transactions in AS400 databasee so I can work on it?
Please advise

I'm investigating a poorly performing procedure that I have never seen before. The procedure sets the transaction isolation level, and I suspect it might be doing so incorrectly, but I can't be sure. I'm pasting a bastardized version of the proc below, with all the names changed and the SQL mucked up enough to get through the corporate web filters.
The transaction isolation level is set, but there is no explicit transaction. Am I right that there are two implicit transactions in this procedure and each of them uses snapshot isolation?
SET NOCOUNT ON;
SET TRANSACTION ISOLATION LEVEL SNAPSHOT;
DECLARE @l_some_type varchar(20),
@some_type_code varchar(3),
@error int,
@error_msg varchar(50);

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?

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,

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?
Are there any scenarios where an un-commited transaction would block further queries?

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.
Thanks
