I have a script contains multiple statements to update multiple tables. How can I make sure that either all statements get executed successfully or no changes apply to the tables (in case one or more errors occur)? I've been searching on Internet and it seems like I need to use Rollback and begin transaction.

I have a job scheduled that imports a table from a Oracle database. The job runs at 3am and reports success. But for some reason when i query the table to see how many records there are, I see the same row count as the day before (it should increase everyday- student enrollment). When i execute the package manually, the table updates fine.

Hi,
I'm using data flow as flat file source -> derived column ->Data Conversion-> oledb destination
I have a fifty thousand record in a delimited file. while processing i got error in 45000th row. In database only 40000 records are there(why is there no all 45000 records). Is there any way to roll back all the 40000 records.
Hi,
I have an application that allows users to synchronize SQL CE data with the server. I would like to implement the functionality wherein if the synch process hits an error, the whole synchronization rolls back.
Is it possible to roll back the Synchronization process? I am using Merge replication over web in the application.
Thanks

My question is how to get IDENTITY_INSERT Incriment Primary Key ID roll back when the application fails.
Using TransactionScope with single connection in DataObject. I am trying to insert row in two dataTable using its own tableAdapter (two tableAdapter).
I have Product table with ProductID primary key with incriment identity. and that ProductID is used to insert row in ProductHistory Table. Lets say Product table has the last ProductID=8 (8 rows) and the next ProductID will be 9.
When I insert row in both table and if the second table insert fails both gets roll back (which is good). but when I insert again another time the Product ID=10 not 9. Is there any way to roll back the ProductID in Product table so when i insert next time it has incriment number instead of gap.
Hi,
I followed Remus' post about not doing 'fire and forget'.
I have two queues, ProcessingSendQueue and ProcessingReceiveQueue.
Once i receive from ProcessingReceiveQueue, activation SP gets called on ProcessingSendQueue and ends conversation.
However,if I then get an exception, the action of the activation SP ( ie the ending of the conversation ) does not get rolled back... is this possible? I would have thought that the action of the activation SP would get rolled back too.
My ProcessingSendQueue activation SP is as follows:
ALTER PROCEDURE [dbo].[ProcessingSendQueue_AP]
AS
BEGIN
DECLARE @dh UNIQUEIDENTIFIER;
DECLARE @message_type SYSNAME;
DECLARE @message_body NVARCHAR(4000);
RECEIVE @dh = [conversation_handle], @message_type = [message_type_name], @message_body = CAST([message_body] AS NVARCHAR(4000))
FROM [ProcessingSendQueue];
IF @dh IS NOT NULL
BEGIN
IF @message_type = N'http://schemas.microsoft.com/SQL/ServiceBroker/Error'
BEGIN
RAISERROR (N'Received error %s from service [ProcessingReceiveQueue]', 10, 1, @message_body) WITH LOG;
END
END CONVERSATION @dh;
END
END
Goofed up and ran an update query. It messed up all the data in a single table. I'm trying not to restore the table from a previous backup since the backup is more than 20 GB. It's going to take forever to restore it. Any advice would be much appreciated!
Thanks!

I have a page that runs a transaction correctly after a button click.
I want to allow someone to click a button that rolls back the transaction, after the transaction runs on the first button click.
I can also successfully roll back within the first button click.
I'm getting a NullReference error when trying to access SqlTransaction.Rollback() outside the button click.
If SqlTransaction.Commit() completes without error can SqlTransaction.Rollback() be called after?
I tried making 'trans' a more global variable and it still gave me the error.
Button Click 1:
Dim trans As SqlTransaction
trans = connection.BeginTransaction()
try
'run SQL Statement
trans.Commit()
Catch e As Exception
trans.Rollback()
throw e
end try
Button Click 2:
trans.Rollback()

View 2 Replies View RelatedHello!I have a developer that is playing around with some SQL statementsusing VB.NET. He has a test table in a SQL 2000 database, and he hasabout 2000 generated INSERT statements.When the 2000 INSERT statements are run in SQL query analyzer, all2000 rows are added to the table. When he tries to send the 2000statements to SQL Server through his app., a random number ofstatements do not get executed. But, SQL Profiler shows that each ofthe 2000 statements are getting sent to the server.I suggested that he add a "GO" statement at the end of the INSERTblock, but the statement fails when that is sent to the server.I know that this is not the ideal manner to insert bulk data to thesystem, but now we are all just curious as to why SQL server doesn'texecute each individual INSERT.Any thoughts?
View 3 Replies View RelatedI would like to know if there is any option to Restrict DML statements in SSMS for a user where the same user should be able to perform these actions through application on particular database.
View 1 Replies View RelatedI have a main table called Stock for example.
One process ( a service ) inserts data into this table , as well as updates certain fields of the table periodically.
Another process ( SQL Job ) updates the table with certain defaults and rules that are unknown to the service - to deal with some calculations and removal of null values where we can estimate the values etc.
These 2 processes have started to deadlock each other horribly.
The SQL Job calls one stored procedure that has around 10 statements in it. This stored proc runs every minute. Most of them are of the form below - the idea being that once this has corrected the data - the update will not affect these rows again. I guess there are read locks on the selecting part of this query - but usually it updates 0 rows - so I am wondering if there are still locks taken ?
UPDATE s
SET equivQty = Qty * ISNULL(p.Factor,4.5) / 4.5
FROM Stock s
LEFT OUTER JOIN Pack p
on s.Product = p.ProductId
AND s.Pack = p.PackId
WHERE ISNULL(equivQty,0) <> Qty * ISNULL(p.Factor,4.5) / 4.5
The deadlocks are always between these statements from the stored procedure - and the service updating rows. I can't really see how the deadlocks occur but they do.
Another suggestion has been to try and use an exists before the update as below
IF EXISTS( SELECT based on above criteria )
( UPDATE as before )
Does this reduce the locking at all ? I don't know how to test the theory - i added this code to some of the statements, and it didn't seem to make much difference ?
Is there a way to make a process ( in my case the stored procedure ) - give up if it can't aquire the locks rather than being deadlocked - which leads to job failures and emails etc ?
We are currently trying to filter down the data that is updated to be only the last few months - to reduce the amount of rows even analyzed - as the deadlocking does seem to be impacted by the number of rows in the tables.
I have a query with huge number of case statements. Basically I need to short this query with getting rid of these hundreds of CASE statements.
Because of the nature of the application I am not allowed to use a function, and just wondering if there is a possible way to rewrite this with COALESCE().
SELECT
CASE WHEN A.[COL_1] LIKE '%cricket%' THEN 'ck' + ',' ELSE '' END +
CASE WHEN A.[COL_1] LIKE '%soccer%' THEN 'sc' + ',' ELSE '' END +
....
CASE WHEN A.[RESIUTIL_DESC] LIKE '%base%ball' THEN 'BB' + ',' ELSE '' END
FROM TableName A
fix the below SP which is having cursor output with an alternate logic which can make the SP work.(may be using temp table or any other option)

We have a high volume database with 1000's of users and 1000's of procs. Our application enforces a 20 second timeout on all connections.
We can't adjust the 20 seconds - this is a business rule.
It sometimes happens that a proc does not complete within 20 seconds and then times out halfway though. This causes data inconsistency where 50% of the code was saved to the DB and 50% was not - seeing that a stored proc is not transactional and therefor does not roll back the code.
We can't put the code in a TRANSACTION in order to roll back when a time out occurs, because this causes exclusive locks on the tables.
So I guess my question is:
Is it possible to undo/rollback all the code in a proc when a timeout occurs - without using a TRANSACTION? And if a TRANSACTION is the only way - how do I avoid the exclusive lock and blocks?
I was trying to configure maintenance plan to take nightly full database backup and Log backup. I was trying to configure it like in attached file. Any links that i can follow and configure as in attached file.
View 7 Replies View RelatedI'm having a hard time to getting back an xml data back from a stored procedure executed by an Execute SQL task.
I'm passing in an XML data as a parameter and getting back resulting XML data as a parameter. The Execute SQL task is using ADO connection to do this job. The two parameters(in/out) are type of "string" and mapped as string.
When I execute the task, I get the following error message.
[Execute SQL Task] Error: Executing the query "dbo.PromissorPLEDataUpload" failed with the following error: "The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 2 ("@LogXML"): Data type 0xE7 has an invalid data length or metadata length.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
I also tried mapping the parameter as XML type, but that didn't work either.
If anyone knows what's going on or how to fix this problem please let me know. All I want to do is save returning XML data in the parameter to a local package variable.
Thanks
When viewing an estimated query plan for a stored procedure with multiple query statements, two things stand out to me and I wanted to get confirmation if I'm correct.
1. Under <ParameterList><ColumnReference... does the xml attribute "ParameterCompiledValue" represent the value used when the query plan was generated?
<ParameterList>
<ColumnReference Column="@Measure" ParameterCompiledValue="'all'" />
</ParameterList>
</QueryPlan>
</StmtSimple>
2. Does each query statement that makes up the execution plan for the stored procedure have it's own execution plan? And meaning the stored procedure is made up of multiple query plans that could have been generated at a different time to another part of that stored procedure?
Does anybody know of a way to rollback SQL Server 2005
databases back to SQL Server 2000? Is there a way of doing it without
resorting to Copy Database Wizard? I love to find a way of attaching a SS 2005 database
to a SS 2000 instance without any issues.
I recently upgraded to SS 2005 and I am very unhappy with the SS 2005 and I
want to rollback to SS 2000, which was a lot more stable. I am having
several major issues that are affecting my whole company's day-to-day
operations and the managers are not happy. Some of the issues include
night time batch running very sluggish for no apparent reason. This is a
biggest problem because it only occurs once or so a week and causes a disturbance
with the daily activities when the night time processing isn€™t completed on
time. The rest of the time, the batch processing runs great, even a little better then on SS 2000. I
don't believe it is a matter of my application needing to be retuned because if
that was the case, then why isn't it running sluggish every night? Also,
it's never the same day that the sluggish behavior occurs. If it was occurring
on the same night, then I would have something to investigate within our
application, but it doesn't. Another issue that I am having involves a
night time job that restores a copy of the production database to the Data
Warehouse server to be used for updating the data warehouse. Again, most
of the time it runs great (~2 1/2 hours), but once or twice a week, it goes
stupid and takes 6 1/2 hours for no apparent reason. Again, it is not happening
the same day either, which could give me something to invesigate. On SS 2000, this same job ran flawlessly. Never I did I run into situation that the
database restoration took that long to run. Even another issue involves a SQL Server Agent Job that was put into suspended
state. What's a suspended state and how can I get it out of suspended
state? I can find no information about suspended state in BOL. I
did a Google and nothing came up. If this suspended state was put
in for security reasons, great, but then tell me how I can remove the suspended
state. I am also not happy with the
fact that I can't get accurate information about the queries that are actively
running at that particular moment. In SS 2000, when I noticed high CPU
usage on the server, I would run the sp_who2 active stored proc and it would
show me all the active thread and how much CPU it was consuming. I would
then find the running threads with the highest CPU numbers and investigate the
query and see if we could improve it. Now in SS 2005, I get in the same
situation and run the sp_who2 stored proc, and there is no smoking gun.
All of the active threads are showing very little CPU usage, which I am very
suspect of. What the heck happen to sp_who2? I looked at some of
the other ways of looking at running processes (i.e... sys.sysprocesses) and
they don't appear to be giving the information that I need.
I am very unhappy and I just want to roll back to SS 2000 and wait a couple of
years before I upgrade to SS 2005.

Just wonder whether is there any indicator or system parameters that can indicate whether stored procedure A is executed inside query analyzer or executed inside application itself so that if execution is done inside query analyzer then i can block it from being executed/retrieve sensitive data from it?
What i'm want to do is to block someone executing stored procedure using query analyzer and retrieve its sensitive results.
Stored procedure A has been granted execution for public user but inside application, it will prompt access denied message if particular user has no rights to use system although knew public user name and password. Because there is second layer of user validation inside system application.
However inside query analyzer, there is no way control execution of stored procedure A it as user knew the public user name and password.
Looking forward for replies from expert here. Thanks in advance.
Note: Hope my explaination here clearly describe my current problems.
Hi,
I am having such a problem. I have SQL Express installed on the windows 2003 server and originally I installed instance1 of SQL Server 2005. When I installed Instance1, I remember having problems with remotely connecting to that instance1, but somehow I fixed it. Now I installed instance2 and I started having remote connection issues again with that instance2. I am able to connect to instance1 but not instance2. I checked settings for both instances and they look identical.
I turned firewall off for now. I checked TCP settings using surface area configuration (allowing both local and remote connections). I turned off VIA protocol. I specified TCP properties to use dynamic port for that instance2.
In the sql native client configuration I have the following order#: 1. Shared memory, 2. tcp, 3. np, 4. VIA(Disabled). TCP is configured to use 1433.
I have no clue about what is going on. Sometimes I am able to connect remotely and sometimes I get the following error:
"A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - The specified network name is no longer available.) (.Net SqlClient Data Provider)."
When I connect locally - everything connects fine. File sharing is also checked, it works etc...
Thanks for help!!!

I have successfully installed SQL Server 2005 SP1 but when I go to the "Microsoft Update" site it is still shown as required. I have tried going back to an old image of the PC and installing SQL Server 2005 and SP1 again but still the "Microsoft Update" page is not picking up the fact that SP1 has installed successfully. Anyone had the same problem or know of a fix?
