Hi all,
I am have database consist of 10 tables, I want to make log transactions for this tables, So any act happened on these tables, such as adding or modifying or deleting record, I want to put this information somewhere in the database, to determine the user who has done such acts on these tables.
I would high appreciate for any assistant.
Hello 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!
Chris.
Hello,
I've been redirected here from the Transaction Programming forum becuase I have e peculiar issue with SQL 2005 running INSERT stored procs from multiple WCF services all withing a TransactionScope.
The original post is http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2720665&SiteID=1&mode=1
The story goes, I have SRVC A with starts a TransactionScope which in turn calls SRVC B & C in sequence based on processing rules.
SRVC A is a Sequential Workflow which Starts and Completes the TransactionScope
SRVC B Creates a new Customer into the database
SRVC C Creates new Accounts for that Customer and Initialises the accounts with funds
The DB Tables underneath are Customer, Account and AccountLog
DDL
Code Block
CREATE TABLE [Member].[Customers](
[CustomerId] [int] IDENTITY(1,1) NOT NULL,
[Name] [varchar](32) NOT NULL,
[CreatedUtc] [datetime] NOT NULL ,
CONSTRAINT [PK_Customer] PRIMARY KEY CLUSTERED
(
[CustomerId] ASC
)
CREATE TABLE [Bank].[Accounts](
[AccountId] [int] IDENTITY(1,1) NOT NULL,
[CustomerId] [int] NOT NULL,
[CurrentBalance] [money] NOT NULL,
[LastUpdateDate] [datetime] NULL,
[CreatedDate] [datetime] NOT NULL,
[timestamp] [timestamp] NOT NULL,
CONSTRAINT [PK_Bank_Account] PRIMARY KEY CLUSTERED
(
[AccountId] ASC
)
) ON [PRIMARY]
GO
ALTER TABLE [Bank].[Accounts] WITH CHECK ADD CONSTRAINT [FK_Account_Customer] FOREIGN KEY([CustomerId])
REFERENCES [Member].[Customers] ([CustomerId])
CREATE TABLE [Bank].[AccountLog](
[AccountLogId] [int] IDENTITY(1,1) NOT NULL,
[AccountId] [int] NOT NULL,
[Amount] [money] NOT NULL,
[UtcDate] [datetime] NOT NULL,
CONSTRAINT [PK_Bank_AccountLog] PRIMARY KEY CLUSTERED
(
[AccountLogId] ASC
)
) ON [PRIMARY]
GO
ALTER TABLE [Bank].[AccountLog] WITH CHECK ADD CONSTRAINT [FK_AccountLog_Account] FOREIGN KEY([AccountId])
REFERENCES [Bank].[Accounts] ([AccountId])
NB. I've removed most fields not essential for this example.
So from SRVC A I invoke SRVC B and the Customer is created, however when I get to SRVC C and the accounts are to be created I get a lock. Only when the Transaction aborts due to timeout, do I see in SQL Profiler that the call to the SP that created the Account is executed but eventually rolls back as it is part of the distributed transaction.
Now, If I set the Isolation level in the TransactionScope to ReadUncommitted (urgh) the problem remains. When I set the IsolationLevel to Read Uncommitted in the SP that creates the account the problem remains but when I remove the FK constraint the problem disappers. The other curious thing is that with the Customer -> Account FK removed and when SRVC C calls to insert funds into the AccountLog which also updates an aggregated total in the Account from within the same transaction scope and with Account -> AccountLog FK constraints in place there is no locking even with Isolation Serializable.
I'm quite at a loss as to what could be causing these issues. If anyone has any suggestions I would greatly appreciate any help.
Thanks

I 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.
Our Transactions/sec counter jumped quite a bit when we moved to SQL Server 2005. The move coincided with increased load so we didn't think anything of it until recently. Upon further review, the counter just seems too high.
There was an article in SQL Server magazine a few years ago by Brian Moran where he states, "Transactions/sec doesn't measure activity unless it's inside a transaction. Batch Requests/sec measures all batches you send to the server even if they don't participate in a transaction." He goes on to say that Transactions/sec will be skewed lower because it is a subset of Batch Requests/sec. (http://www.sqlmag.com/Article/ArticleID/26380/sql_server_26380.html)
The article was written for SQL Server 2000. We conducted tests in 2000 and found what he said to be right on the money. SELECT statements increased Batch Requests/sec, but not Transactions/sec. UPDATE/INSERT/DELETE statements increased both in lockstep. Makes perfect sense so far.
We conducted the same tests in 2005 and found a radically different story. While SELECT statements behaved the same, UPDATE/INSERT/DELETE statements showed Transactions/sec skyrocket 2-10x more than Batch Requests/sec for the duration of the statement. In other words, a single transaction submitted by our application fires off exponentially more transactions than the one we submitted. I was unable to pinpoint exactly what these "hidden" transactions were actually doing. Is this something that occurred in 2000 but simply wasn't reported? Or is it new behavior in 2005?
While trying to answer these questions we noticed a second strange behavior in 2005. When no queries are being executed the Transactions/sec counter still jumps every six seconds like clockwork. And these phantom transactions number in the thousands. We tried to use profiler to capture what SQL was being executed, but nothing shows up in any SQL Statement or Batch event. However, when we turned on the SQLTransaction event we found it, sort of. An object called GhostCleanupTask runs every six seconds causing thousands of transactions. We don't know exactly what it is doing, but we noticed that it ran consistently on some databases, but never on other databases. Both sets of databases are identical and in use.
So, all of this investigation leads me with three final questions.
1. What is behind all the extra transactions caught by perfmon when I submit a single transaction?
2. What is GhostCleanupTask and why does it take so many transactions? (And why does it only run on certain databases?)
3. If a potential customer asks for our Transactions/sec count, is it accurate to give them the big number, knowing that our application is only actually submitting a fraction of that? On the other hand, the system apparently is actually doing that many transactions. (For instance, on our production server during peak, Batch Requests/sec is about 4,000, while Transactions/sec hits 26,000.
Any insight would be much appreciated.

Help, 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 1 Replies View RelatedHi 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 All,
I want to make a simple http request from SQL to a web server, something like this:
HTTP_REQUEST('http://www.domain.com/page.asp?var=value')
I don't want to get any response back, just a request.
Is there something like this in SQL 2005? or if anyone had wrote something like this.. I'll be greatfull if you can help me.
Thanks in advance

question : HOW?

Hi all,
I'm kinda stuck with the following issue and would apreciate some help with it.
Basically i need to have a user within SQL that has rights to restore databases and is the owner of that database so it can alter the data. The problem i face is that at this moment i see no other way then making that user either member of the server role "sysadmin" or "serveradmin".
Anyway, these roles have to much rights. I tried using the dbcreator role which will make a the needed user db_owner but only when a new database is created, not when a database is restored.
Tried to resolve this with a DDL trigger and then temporarily run as a user with serveradmin rights, however there is no system event for restore database, so that doesn't work either.
Anybody got any suggestions?

I work for a consulting firm. Customers are reporting being annoyed with the popup "Help Make Microsoft SQL Server 2005 Better". Some customers don't want to be bothered with this even once. Is there a way to keep this popup from ever appearing?
The customers are intelligent. They understand why the popup appears and what its purpose is. The only point to address is that the customers have paid for SQL Server, they are annoyed by this feature and they want a way to suppress it. I want to give the customers what they want. When customers tells me something is a nuisance, it's not my place to tell them they are wrong.
Hi ~
I made simple stored procedure that is to update user information following as...
ALTER PROCEDURE UpdateUserProfile( @user_id uniqueidentifier, @user_firstname nvarchar(50), @user_lastname nvarchar(50), @user_birth nvarchar(20), @user_gender nvarchar(20) )
AS
UPDATE user_profile SET user_firstname = @user_firstname, user_lastname = @user_lastname, user_birth = @user_birth, user_gender = @user_gender WHERE user_id = @user_id RETURN
When I tried to save this procedure, I faced on "Invalid Object : UpdateUserProfile" error message.
What's the problem ?
I am new to this so I hope I'm doing it right.

I did run upgrade advisior to check the existed sql 2005 standard edition to upgrade to enterprise editon. I got the following error message:
SQL Server version: 09.00.1399 is not supported by this release of Upgrade Advisor
Is it means the upgrade advisor can only work on from 7.0, 2000 to 2005? If I need check from standard to enterjprise in 2005, what kind of tool I can use?

I am sorry if this is the wrong forum for this question but I can not find better fit.
I am using Visual Studio 2005 to write an asp.net web site which includes an SQL data base. In the databaseI have a table called 'ACCOUNTS' which has primary key column called 'ID' and a nvarchar column called 'Name'.
I want the values in the 'Name' column to be unique in the table so that all accounts have unique names. I don't want to make the 'Name' column the primary key because I want people to be able to change the name of their account after it has been created.
It seems to me there must be some way to add such a constraint to the table but I can find none. I have searched the documentation and seen loads of references to unique columns but I can't find any way to set a column to unique thru the IDE (or any other way). Can anyone help me?
Thanks in advance for any help.

In sql server 2000, I created some custom database roles called ProjectLeader and Developer. I would make these roles a member in the fixed database roles so that I would only have to add the user to the ProjectLeader or Developer role once and they would presto-magico have the security I wanted them to have with no unecessary mouse clicking. I'm not sure how to repeat this process in 2005? Management Studio doesn't seem to allow you to add a role as a member in another role. Is there a work around or solution for this?

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,

View 2 Replies View RelatedIs 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?
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
I have a small database that I have been testing.I get an error about a transaction deadlock.The code is in stored procedures and I added transactions to the sp'sbut the error happened again.I wrapped the whole sp in just one transaction and I don't have anyindex on the tables.When I test just by running a program that sends 3 calls at a time itwill get a deadlocked transaction as I send 6 or 9 at a time.I am not sure how it can have a deadlocked transaction after I usedtransactions(begin and commit) in the sp's.Steve
