SQL 2012 :: Enable Promotion Of Distributed Transactions For RPC - Set To TRUE Or FALSE
May 14, 2015
It is my understanding that when having LinkedServers, the option "enable promotion of Distributed Transactions for RPC" should be set to TRUE, so we can rollback , if needed, remote transactions. At least, that's my understanding of that setting.
Having said that, the TRUE setting is affecting this particular TSQL code, inside an sproc, which I would prefer not to alter:
Insert into #TempTable
EXEC ServerB.MyDatabase.MyStoreProcedure
@param1= '',
@param2= ''
When set is set to TRUE (current setting) I get this error:
OLE DB provider "SQLNCLI11" for linked server "ServerB" returned message "The partner transaction manager has disabled its support for remote/network transactions.".
Msg 7391, Level 16, State 2, Line 28
The operation could not be performed because OLE DB provider "SQLNCLI11" for linked server "ServerB" was unable to begin a distributed transaction.
... when set to off, the error goes away.

I have a cube that has a Dimension set up with several values some of which are bools. While Browsing in Excel or SSMS, two new values, when used as a filter shows (All) (Blank) and (True) for selections instead of (All) (True) and (False).

I vaguely remember reading somewhere that all distributed transactions are executed at Serializable Isolation Level "under the covers."
1. Is this true?
2. What does "under the covers" mean in this case; i.e. will I not see the isolation level represented accurately in requests?

I have a stored procedure that has a boolean (bit) field passed to it (@emailcontract). If a user checks the check box on the webform I would like my where to return only the records where the email_contract column is true. If they don't check the check box I would like it to return records where email_contracts is true or false.
What would my where cluse look lile for this?

Hi,
I need to check the existence of a row in a table.
So i am using an if condition
like
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER PROCEDURE [dbo].[CheckNOAStages]
@NOAID int,
@StageCode nchar(20)
AS
BEGIN
SET NOCOUNT ON;
Declare @Count int
Select @Count =Count(NOAId) from NOAStages where NOAID=@NOAID and StageCode=@StageCode
if (@Count>0)
Begin
return 1
end
else
begin
return 0
end
END
The stored proc is executing but on the Data Access Layer
I have this
Boolean exists = Convert.ToBoolean (Execute.ExecuteReader(spCollection, dbSQL));
Some how I am always getting false . How can I fix this?
Thanks

Hello
I am exporting an SQL Server table to a comma delimited text file. The values of Columns defined as Bit are exported as "True" or "False", but I would like that in the file appear 1 or 0 instead (with no surrounding double quotes). How can I acomplish that?
I tried using a Transformation and convert to single byte unsigned integer, but True values are exported as "255" and False values as "0". Why?
Thanks a lot.

Hi there, I've tried googling this (and looking at the many questions on the forum :) but I've not managed to find a decent tutorial / guide that describes a method for using checkboxs to insert true/false flags in a MS SQL db. The db field i'm setting has type set to "bit", is this correct? And secondly (its been a long day!) I just cant figure out the code to assign the bit 1 or 0 / true or false. This is what I've got so far but it's not working........Function InsertProduct(ByVal prod_code As String, ByVal prod_name As String, ByVal prod_desc As String, ByVal prod_size As String, ByVal prod_price As String, ByVal prod_category As String, ByVal aspnet As Boolean) As Integer Dim connectionString As String = "server='server'; user id='sa'; password='msde'; Database='dbLD'" Dim sqlConnection As System.Data.SqlClient.SqlConnection = New System.Data.SqlClient.SqlConnection(connectionString) Dim queryString As String = "INSERT INTO [tbl_LdAllProduct] ([prod_code], [prod_name], [prod_desc], [prod_size], [prod_price], [prod_category],[aspnet]) VALUES (@prod_code, @prod_name, @prod_desc, @prod_size, @prod_price, @prod_category, @aspnet)" Dim sqlCommand As System.Data.SqlClient.SqlCommand = New System.Data.SqlClient.SqlCommand(queryString, sqlConnection) sqlCommand.Parameters.Add("@prod_code", System.Data.SqlDbType.VarChar).Value = prod_code sqlCommand.Parameters.Add("@prod_name", System.Data.SqlDbType.VarChar).Value = prod_name sqlCommand.Parameters.Add("@prod_desc", System.Data.SqlDbType.VarChar).Value = prod_desc sqlCommand.Parameters.Add("@prod_size", System.Data.SqlDbType.VarChar).Value = prod_size sqlCommand.Parameters.Add("@prod_price", System.Data.SqlDbType.VarChar).Value = prod_price sqlCommand.Parameters.Add("@prod_category", System.Data.SqlDbType.VarChar).Value = prod_category If chkAspnet.Checked = True Then sqlCommand.Parameters.Add("@aspnet","1") Else sqlCommand.Parameters.Add("@aspnet","0") End If Dim rowsAffected As Integer = 0 sqlConnection.Open Try rowsAffected = sqlCommand.ExecuteNonQuery Finally sqlConnection.Close End Try Return rowsAffected End Function Sub SubmitBtn_Click(sender As Object, e As EventArgs) If Page.IsValid then InsertProduct(txtCode.Text, txtName.Text, txtDesc.Text, ddSize.SelectedItem.value, ddPrice.SelectedItem.value, ddCategory.SelectedItem.value, aspnet.value) Response.Redirect("ListAllProducts.aspx") End If End SubAny help would be appreciated or links to tutorials.ThanksBen

I want to pass a single char to a query and use that to set two flags.
(
@ID int,
@AssessedID int,
@CompetencyID int,
@Status char,
@Creator int
)
AS
UPDATE P4_Assessment
SET P4_Cancelled_f = (@Status = ('C')),
P4_Competent_f = (@Status = ('P')),
P4_Date = getdate(),
P4_Creator = @Creator
WHERE P4_ID = @ID
I want to set the P4_Cancelled_f to true (if @Status = 'C') or false if it doesn't.
This sort of syntax is fine in C#, but fails in a query. I also tried using IN (@Status IN ('C'))
Is this sort of logic possible in TSQL or should I use two parameters and set them in my code as 1 or 0?
TIA

Actually title should be returns true when should false.
I want to check a table to see if a record already exists, if it doesn't then insert it, else do nothing:
IF NOT EXISTS
(SELECT 1 FROM Table1 WHERE col1 = 'Test')
BEGIN
INSERT INTO Table1 (col1) VALUES ('Test')
END
The value 'Test' is already in the database yet, the code is saying it's not and trying to insert it, resulting in duplicate key errors.

When I enter a a true or false value into a boolean field, what is the proper way to enter it? I'm using:

Hi everyone.
I've got a Select query that pulls out some data from my database. Two of the columns are both booleans (bit's of size 1) so they come back as TRUE and FALSE - which I thought was fine.
However, the users are wanting to see YES and NO since they find TRUE and FALSE confusing (yes I know how silly that sounds).
Is there any way I can do this?
My query is like this:
SELECT [stuff], [things] FROM [table1], [table2] WHERE [table1].[condition] = [table2].[condition]
Thanks

Hai,
I am trying to design a database for storing trule/false questions.
I have no need to store any thing like chapters are topic. I want to just design a bare minimum tables for just storing questions and its responses.
So does the following tables and fields suffice to achieve that?.
Questions_table(id(autogenerated),course_id,Questi on(text type))
id field uniquely identify each question, course_id(ex:CRS235) is used to identify which course a particular question belongs to, and Question filed store actual question.
Response_table(id,response)
Response field is of int type, 1 for correct answer, 0 for wrong answer. I am not storing options for each question because every question has same options that is True/False.
So, will this work. Please advice and I would appreciate if any one can point me to a good resource on the web.
Thanks,

Hi,
I'm using SSIS to update the destination table.
Both servers are running identical SQL Server 2005 versions.
I want to copy data and replacing existing data WITHOUT dropping the destination table first.
The SSIS package works when:
1) DropObjectsFirst = TRUE
2) CopyData = TRUE
3) ExistingData = REPLACE
The SSIS package does not work when:
1) DropObjectsFirst = FALSE
2) CopyData = TRUE
3) ExistingData = REPLACE
The error I get is the "destination table already exists". Of course, it already exists. I just want to copy/update the destination table. So, why does SSIS insist on dropping the table first?

Hi to everyone!
Any experience handling a Store Procedure that has distribution transactions?
Here is a story.
We have a store procedure #1 that inserts or updates data in two tables A and B on SQL Server 7.0 then it calls another store procedure #2 that:
1. updates C table in the same database on SQL Server from Oracle Server
2. deletes that record on Oracle Server
3. inserts a record on Oracle from table A
4. inserts the same record into table D on SQL Server from Oracle Server.
People who wrote store procedure #1 put Commit Tran before executing #2.
The questions are:
1. Is it correct that we don't have Commit Tran for #2?
2. What do you think about Nested Begin - Commit Tran?
Any help is highly appreciated.

Does SQL Server actually support distributed transactions over, say, two tables in different databases but that reside on the same server? When I try to execute such a transaction in which one part of the transaction violates referential integrity and hence should not be executed, causing the rest of the transaction to, supposedly, rollback, the transaction does not roll back but instead produces an error message and executes the second, valid half of the transaction anyway.
Any help or suggestions gratefully accepted.

Hi There
I realize this is probably a basic question or at least i hope so but i cannot get distributed transactions working.
BOL is just driving me in circles.
I am running SS2000, MSDTC is up and running on the server.
I have added a trigger to a table where on insert or update the triggers fires and inserts a row to a remote server.
When i execute the update or insert i get the error:
Cannot start a distributed transaction.
I have tried stating BEGIN DISTRIBUTED TRANSACTION before the update but i get the same error, i have also read up on SET REMOTE_PROC_TRANSACTIONS, but this is not a remote sp.
Can anyone please reccomend a good link as to how to get distributed transactions to work.
Thanx

I am using SQL server 7.0 and i have created oracle8i linked server(Using MSDAORA as provider) in it.
When i run distributed queries between SQl server and Oracle server it works fine.But when i try to run distributed transaction between two servers ( BEGIN DISTRIBUTED TRANSACTION..)it reports an error saying Distributed transactions are not supported by MSDAORA.
My question is; is it possible to run distributed transaction between SQL server and oracle server (where oracle server is a linked server in my SQL server)?
Actually i want to run this transaction in DTS package which updates and transfers data amongst various servers.
Thanx

We just upgraded from SQL 7 to 2000 and for some reason I am unable to perform distributed transactions. I keep getting the following error:
OLE DB error trace [OLE/DB Provider 'MSDASQL' ITransaction Join:: JoinTransaction returned 0x8004d00a]. Operation could not be performed because the OLE DB provider 'MSDASQL' was unable to begin a distributed transaction
I tried a few of the fixes recommended on the microsoft website but they did not solve the problem. We are still using the same O/S (Windows 2000 Pro), so the only thing that has changed is the server.
Any help would be appreciated.

I am attempting to update an oracle table from a insert trigger on my SQL table. When using a trigger to run a sql command against the ole db oracle client (linked server) a distributed transaction is initiated and i get a message stating. "The operation could not be performed because the OLE DB provider 'MSDAORA' was unable to begin a distributed transaction."
I can update the oracle table through a query however just not throught a distributed transaction.
However according to all the documentation i can find it states that I should be able to perform this.
Can anyone shed any insight?

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
Andy

Hi there,
I have two SQL servers, SERVERA and SERVERB. They are on two different VLAN's within our corporate network. They are physically only about 5 feet apart. SERVERA is SQL2005 while SERVERB is SQL2000. I am running a distruted transaction as a result of an insert on SERVERA which then causes a Stored procedure stored on SERVERA to insert a record on a table on SERVERB. I know my syntax is correct, 'cause I can get the Process to work between two servers (one SQL2000 and the other SQL2005) on the same VLAN. But when I run it in the problem environment, I get the following error message:
SQL Execution Error
Executed SQL Statement: INSERT INTO Tablea(recordid, recordtext) values(3, 'Testagain')
Error source: .Net SQLClient Data Provider
Error Message: The operation could not be performed because OLE DB provider "SQLNCL1" for linked server "SERVERB" was unable to being a distributed transaction.
I have checked to make sure that MSDTC is running and it is on both servers.
Any help would be greatly appreciated. Thanks! - Eric-

Hi there,
We have two servers, one (we'll call 'SERVERA') has SQL2005 running on it. The second (we'll call 'YELLOWSTEONE') is running both SQL2000 and SQL2005 on it. The SQL instances on YELLOWSTONE are 'YELLOWSTONESQL2000' and 'YELLOWSTONESQL2005'. As a linked server, I have an entry for YELLOWSTONE which then links to the SQL Server of YELLOWSTONESQL2000 on the server network name of YELLOWSTONE. By them selves they seem to run fine. However, if I have trigger that Runs on SERVERA to do a distributed transaction on 'YELLOWSTONESQL2000', I get the following error:
OLE DB provider "SQLNCLI" for linked server "YELLOWSTONE" returned message "Login timeout expired".
OLE DB provider "SQLNCLI" for linked server "YELLOWSTONE" returned message "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.".
Msg 2, Level 16, State 1, Line 0
Named Pipes Provider: Could not open a connection to SQL Server [2].
If You can provide me any assistance, I would greatly appreciate it. Thanks! - Eric -

"The partner transaction manager has disabled its support for remote/network transactions. (Exception from HRESULT: 0x8004D025)" The database I have used is northwind database and pubs database which is by default in sql server 2000. So, Kindly let me know how to proceed further.

Hi,I am seeking the help of volunteers to test some software that I'vedeveloped which facilitates distributed two-phase commit transactions,encompassing any resource manager (e.g. SQL/Server or Oracle) controlled byMicrosoft's Distributed Transaction Coordinator in a Windows2000environment, with any resource manager under the control of DECdtm (e.g. Rdb(or Oracle via the XA Veneer)) in a VMS environment.[Yes, at some stage, I hope to sell this software and make money out of it,so unless you have a large philanthropic streak or are simply a techie wholikes to stay on top of Windows<->VMS connectivity issues, then you may wishto look away now. But if you do choose to participate, then rest assuredthat I have no interest in your personal or company details. (Just yourwork-rate :-)]What differentiates my Transaction Manager software from existingTransaction Monitor packages that are already in the marketplace (and whyyou should be interested) is that it is based on the Transaction InternetProtocol TIP standard. (RFC 2372) For those of you who don't know, thebeauty of TIP's "Two-Pipe" strategy is it's application-pipe (or middleware)neutrality. Whereas most XA implementations mandate homogenous TransactionMonitor deployments (such as Tuxedo everywhere, Encina everywhere, MQSerieseverywhere, ACMSxp everywhere and so on . . .), hotTIP from TIER3 Softwaregives you complete freedom to choose the middleware product(s) that bestsuite your particular application and heterogeneous network needs.Would you like to talk to VMS with TIER3 Sockets, COM or DCE/RPC? BEAMessageQ, IBM MQSeries or HTML? The choice is yours and yours alone. Butonce you realize that you need to encase your critical transactions withinthe ACID properties of a true Heterogeneous Two-Phase Commit then you willcome to the conclusion that you need a Transaction Manager that looks a lotlike this.Another drawback of traditional "One-Pipe" strategies is that they precludethe run-time determination of transaction participants. (Functionalitywhich may be advantageous in a wide-area or Internet based application.)Anyway, this is what I have: -On the Windows side, you need absolutely *NO* additional software! I'llreply to this note with a brief description of the COM+ and DTC functionsthat you would need to invoke in order to successfully push a MTS/DTCtransaction to VMS. NB: These are standard Windows APIs that are fullydocumented on MSDN.On the VMS side, I have a VMSINSTAL saveset that (all zipped up) is some150KB that I'm happy to e-mail to you along similar lines to the VMShobbyists (non-commercial use) license. I'll reply to this note with anInternet Daemon (INETd) example of code that uses my software to cedetransactional control, over an SQL insert into a Rdb database, to MTS/DTC.It's under 500 lines long and contains all of the DCL, 3GL, SQL required toproduce a working example of a TIP-2PC capable TCP/IP auxiliary server. Thisexample will insert a row into the MF_PERSONNEL.Employees table on the VMSside in co-operation with Windows2000 MTS/DTC client that is inserting a rowinto the NORTHWIND.Employee table. Commit them all or roll them all back.So, in summary, If you'd like to volunteer to put hotTIP through it's pacesthen simply reply to this mail.Regards Richard MaherPS. The following are a few functionality restrictions with the currentversion of my software that may effect your decision to participate: -1) Transaction has to be started/mastered/coordinated by W2K MTS/DTC2) Transactions cannot be PULLed from VMS and must be PUSHed from W2K3) No cluster-wide recovery.(If a txn falls over after being prepared then you have to wait for thatspecific node to become contactable again even though that lovely RDMrecovery job is sitting on another node protecting the database until myhotTIP TM tells it to commit or abort.)4) There is currently no Alpha or Itanium version available. The Alpha portis currently in progress but, for the time being, you'll either need a VAXor a VAX emulator on your PC.

We get the below error while performing a distributed transaction on linked server. We have several linked servers configured in the source server and all of them succeed with the distributed transaction except on one.
We did all the basic troubleshooting and moreover the distributed transactions work fine if we use a remote server instead.

Hi,
I am using distributed transactions where in I start a TransactionScope in BLL and receive data from service broker queue in DAL, perform various actions in BLL and DAL and if everything is ok call TransactionScope.Commit().
I have a problem where in if i run multiple instances of the same app ( each app creates one thread ), the threads pop out the same message and I get a deadlock upon commit.
My dequeue SP is as follows:
CREATE PROC [dbo].[queue_dequeue]
@entryId int OUTPUT
AS
BEGIN
DECLARE @conversationHandle UNIQUEIDENTIFIER;
DECLARE @messageTypeName SYSNAME;
DECLARE @conversationGroupId UNIQUEIDENTIFIER;
GET CONVERSATION GROUP @conversationGroupId FROM ProcessingQueue;
if (@conversationGroupId is not null)
BEGIN
RECEIVE TOP(1) @entryId = CONVERT(INT, [message_body]), @conversationHandle = [conversation_handle], @messageTypeName = [message_type_name] FROM ProcessingQueue WHERE conversation_group_id=@conversationGroupId
END
if @messageTypeName in
(
'http://schemas.microsoft.com/SQL/ServiceBroker/EndDialog',
'http://schemas.microsoft.com/SQL/ServiceBroker/Error'
)
begin
end conversation @conversationHandle;
end
END
Can anyone explain to me why the threads are able to pop the same message ? I thought service broker made sure this cannot happen?
