I am working on of the T-sql statement that do updates. This statement is running in the job. We set up the notification reached to operator when the job failed.
,
But I need whenever the transactions are rolled back, it has to notify to the team. Below are the steps in the job.
DECLARE @NextRunDate DATETIME = DATEADD(hh,2,CAST(CAST(DATEADD(day,1,GETUTCDATE()) as DATE) as DATETIME))
BEGIN TRY
BEGIN TRANSACTION
UPDATE [RECompanyTask]
SET NextRunDate = @NextRunDate
WHERE SetupOptions = 0 AND [Enabled] = 1
I am just starting to falmiliarize myself with SQL transactions... I just created an SQL transaction... The first statement gets a value, if the value equals "" then the second statement executes... So if the value <> "" Then the second statement wont execute... What would happen in this scenario if the .Rollback is triggered? Heres my code:
Try conSqlConnect.Open() objTransaction = conSqlConnect.BeginTransaction cmdSelect.Transaction = objTransaction cmdInsert.Transaction = objTransaction dtrdatareader = cmdSelect.ExecuteReader() While dtrdatareader.Read() varCheckNumber1 = dtrdatareader("Status") End While dtrdatareader.Close() If varCheckNumber1 = "" Then cmdInsert.ExecuteNonQuery() End If objTransaction.Commit Catch objTransaction.RollBack Return "00" Finally If conSQLConnect.State = ConnectionState.Open Then conSqlConnect.Close() End If End Try
i have 4 flat files from a source folder which updates four different tables, this has to be done parallely,on success of this transaction the files have to be moved to another folder.
my problem comes here,now if there is any problem in moving any file to another folder,that particular transaction has to be rolledback without affecting others.i tried setting the transaction property of the control flow,but it rollbacks all the transaction..
I have created a table test1 with primary key as given below. I have written a procedure to insert rows. is the rollback transaction given under is correct?. (OR) shall i give the rollback only once at the end?
need more explanation on the rollback transaction.
CREATE TABLE [TEST1] ( [COL1] [varchar] (50) NOT NULL ) ON [PRIMARY] GO
ALTER TABLE [TEST1] WITH NOCHECK ADD CONSTRAINT [PK_TEST1] PRIMARY KEY CLUSTERED ( [COL1] ) ON [PRIMARY] GO
ALTER PROCEDURE T AS BEGIN TRANSACTION INSERT INTO TEST1 VALUES('A') IF (@@ERROR <> 0) GOTO ERR INSERT INTO TEST1 VALUES('B') IF (@@ERROR <> 0) GOTO ERR INSERT INTO TEST1 VALUES('B') IF (@@ERROR <> 0) GOTO ERR INSERT INTO TEST1 VALUES('C') IF (@@ERROR <> 0) GOTO ERR INSERT INTO TEST1 VALUES('D') IF (@@ERROR <> 0) GOTO ERR ERR: IF (@@ERROR <> 0) ROLLBACK TRANSACTION else COMMIT TRANSACTION
someone deleted data from our sql server in several tables. our backup is from yesterday evening and 150 people worked with the database for 7 hours today so it is not possible to restore the database from backup. is it possible to use the ldf to rollback the transactions deleted the data? Can someone give me an idea?
I have a series of questions about SSIS and transactions. The answers to these questions are probably so obvious that I can't see them, so please feel free to just point out what it is that I'm missing. My transaction-processing experience is very low-level, so I'm probably just not seeing how it's done at the high level of SSIS.
The first question is one that I may know the answer to, so please confirm:
Consider a package with TransactionOption set to Supported. It contains a single Execute SQL Task with TransactionOption set to Required. Is it true that if that Execute SQL Task succeeds, that the transaction commits, and that if the task fails, the transaction rolls back?
Consider another package with TransactionOption set to Supported. It contains a Sequence Container with TransactionOption set to Required. That container contains our same Execute SQL Task, but that is joined to a script task by a "success" precedence constraint. The script task simply returns Dts.Results.Failure. Is it the case that the transaction will roll back? That is, is it truly a simple failure result that would initiate the rollback?
If a DataFlow Task is the one that is set to Required, does that mean that every transactional operation within that task will commit in a single transaction? For instance, if I'm inserting five rows for each input record from a flat file, and if my flat file has 1000 records in it, will I see a single transaction with 5,000 rows? Thanks for your patience!
Hi All, I have set of stored procedures under one transaction where as each SP saves the data in one table and any error occurs then it saves the error details in errorlog table in the same SP. Whenever error occurs, all my transactions including error logging also getting rolled back. I want to keep the error logging part alone when my transaction is getting rolled back..... That is, try { Transaction A { Storedprocedure A StoredProcedure B StoredProceudreC commit Transaction A
} } catch() { rollback A }
Where as, My each SP might contains the statements like, StoredProcedure A {
insert values in table A if ( @@Rowcount =0) insert values in errorlog ('Error occurred in table A') }
Now, if any error occurs in Transaction A, all my values stored in 'errorlog' also getting rolled back. Is that any way to stop rollback only for errorlog table in the entire transaction? (Tried using triggers, that was also not helpfu SavePoint will save unnecessary part also.. ).
Is that any way to track the error and maintain in errorlog?
I€™m using triggers for some more advanced integrity check. The problems is that the same trigger can be run from explicit transaction (this is when I start transaction from .NET) and as autocommit transaction ( very rare, only when we do some maintenance directly with SQL statements).
Currently if I want to rollback transaction from trigger I only issue RAISERROR statements, then .NET application catches this error and generates rollback. But the problem is if trigger is raised from some SQL statements outside .NET application (normally some maintenance work direct from SQL manager ) in that case error is generated but there is no rollback.
Is there any way to distinguish if transaction in trigger is explicit or autocommited, because for autocommited transaction I also need use ROLLBACK TRANSACTION?
Sometimes when I do "alter database ABCD set partner failover" I get the following message: Nonqualified transactions are being rolled back. Estimated rollback completion: 100%.
In 99 percent of the cases after such message the first attempt to use an open connection would also raise an error such as "Exception: A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)"
After the first error all subsequent queries would run perfectly.
I'm receiving the below error when trying to implement Execute SQL Task.
"The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION." This error also happens on COMMIT as well and there is a preceding Execute SQL Task with BEGIN TRANSACTION tranname WITH MARK 'tran'
I know I can change the transaction option property from "supported" to "required" however I want to mark the transaction. I was copying the way Import/Export Wizard does it however I'm unable to figure out why it works and why mine doesn't work.
I have a windows service which store data to a database table named "HistBuffer" (under an SQL server Express 2005) .
Then I have a library which is in charge to collect those stored information in HistBuffer and proceed them. The tricky thing here ( may be not so tricky) is that as long as a new row is inserted to this HistBuffer, my library need to be notified in a way and then can request the data.
how can I do this notification from new rows to my library ?
I want to build an windows application by using a visual C# to Notify the user that his data in the database had been changed ..such like "New Message In Your Mail Box Alert"..So I need to know if there is way that to let the SQL Server send a notify (just like Trigger) ..
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
Hello experts, I made a huge mistake on a production server, ran an update without the WHERE clause. UPDATE myTableSET Field1 = 'SOmetext',Field2 = 'sometext2'Is there a way to rollback? I read something a while ago about transaction logs.SOS!Thanks
HI, Suppose I execute any transaction say inserted some rows. I want to delete my previous transaction using rollback. What is the proper syntax for that. In Query Window: Insert ---------- executed rollback. it was asking for name of the transaction. How to give that. Help me out Thanks Bye
This is my stored procedure. Problem is that a rollback does not happen when there is an error ? How can this be, am starting and ending the transaction?
I have rollback on one of the users. I tried killing her process through Enterprise Manager and Query Analyzer, but I still can see her process on the screen. However, her login is grayed out after I execute the kill query.
I have encountered this problem several times, and the only way I can get clear the rollback is by rebooting the server.
Does anyone have a sugeestion on how to clear the rollback without rebooting.
Hi All A question on DTS ROLLBACK CAPABILITY. Is it possible to setup a DTS pkg to roll back the loaded files if a step fails? If a step fail records inserted by Data Pump to a table should be removed. Is this possible? If so how can we achieve this?
is it possible to roll back a transaction here? i heard that it will be possible only if we wrote the code only in certain block.please tell me the block.
The code inserts into table TABLES. TABLES has a primary key. If the insert statement has no error it should insert 'ROWS INSERTED' to table CONTROL and update table DATETRACKING else insert 'ROWS NOT INSERTED' to table CONTROL and do not update table DATETRACKING. 1- I will like to improve my code if it is possible. 2- Can I use a rollback?
DECLARE @ROWCOUNT INT DECLARE @ERROR INT DECLARE @LASTDT DATETIME
SET @LASTDT =GETDATE() BEGIN TRAN insert tables select 4
SELECT @ROWCOUNT = @@ROWCOUNT, @ERROR = @@ERROR IF (@ERROR <> 0) BEGIN INSERT CONTROL SELECT 'ROWS NOT INSERTED', @ROWCOUNT END ELSE BEGIN INSERT CONTROL SELECT 'ROWS INSERTED', @ROWCOUNT END COMMIT TRAN
IF (@ROWCOUNT > 0) BEGIN UPDATE DATETRACKING SET LASTDATEDL = GETDATE() END
I have SQL server 2000 with SP4, 1.Some of the reason,I want roll back SP4 and I want replace SP3. 2.Is it true SP4 slow down the Quey performance compare with SP3.
My rollback does not work In my SP I want any of cmdS,cmdS2,cmdS3,cmdS4 produces error Rollback must be executed for all of cmdS,cmdS2,cmdS3,cmdS4 . I tested for error producing situation but no rollbak occured. How can I solve this problem. Thanks. Below is my SP . .......... .......... .......... begin transaction .......... ..........If Len(ltrim(rtrim(@cmdS)))>0 execute(@cmdS) If Len(ltrim(rtrim(@cmdS2)))>0 execute(@cmdS2) If Len(ltrim(rtrim(@cmdS3)))>0 execute(@cmdS3) If Len(ltrim(rtrim(@cmdS4)))>0 execute(@cmdS4) If Len(ltrim(rtrim(@cmdS)))>0 or Len(ltrim(rtrim(@cmdS2)))>0 or Len(ltrim(rtrim(@cmdS3)))>0 or Len(ltrim(rtrim(@cmdS4)))>0 Beginif @@ERROR <>0 begin rollback transaction set @Hata = 'Error !' end Else Beginset @Hata = 'Sucessfully executed :)' End End commit transaction RETURN
I just made a transaction which writes and reads some data from a database as one unit. Now, I would like to know, what happens, if this transaction does not commit, but instead performs a rollback? Should I use a boolean loop which keeps on trying the transaction until it commits or is there an alternative? I would appreciate any suggestions or help!
I've some problem in SQL Server 7.0 and hope some one out there will help me with it. The problem is as follows:
When I view a proces in the process info screen, I see one process says "Rollback" in the status window and the spid is greyed out like a system process. In the command window it says, Select and wait type is "Exchange". This is taking too much cpu cycles and causing much of the server to perform very slow.
I tried to kill this session from the ISQL and Enterprise manager, But to still see this process running on with out getting killed. Also this process keeps coming.
Please advice me how to get rid of this and why is it ocurring again and again.
