In the above code when an error is raised in the transaction trans2 the immediate catch is not invoked where as the outer catch is being invoked. I dont know y?. Can anybody help. Thanx
The following two stored procedures works fine. I need to add try catch blocks in the stored procedures. How to do it? Pls modify my stored procedure with try and catch blocks and in the catch block i need to call the Procedure called ErrorMsg which contains error severity.

For every trigger and stored procedure I have a try-catch that writes to an error_log table. The problem is the inner error is not preserved, always get: The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction.
As seen below - though commented out: I tried commiting any transactions - though I didn't create one. I played with the XACT_STATE though that was 0 My test case was last procedure has 1/0
ALTER Trigger [trg_ActivityLogEntryReportsError] ON [dbo].[ActivityLog] FOR INSERT AS

I'm having trouble with a Script Component in a data flow task. I have code that does a SqlCommand.ExecuteReader() call that throws an 'Object reference not set to an instance of an object' error. Thing is, the SqlCommand.ExecuteReader() call is already inside a Try..Catch block. Essentially I have two questions regarding this error:
a) Why doesn't my Catch block catch the exception? b) I've made sure that my SqlCommand object and the SqlConnection property that it uses are properly instantiated, and the query is correct. Any ideas on why it is throwing that exception?
Is there a reason why the following code does not raise an error in my .NET 2005 application? Basically I have a try..catch in my stored procedure. Then I have a try...catch in my .NET application that I want to display the error message. But, when the stored proc raisses the error, the .net code doesn't raise it's error. The .NET code DOES raise an error if I remove the try..catch from the SQL proc and let it error (no error handling), but not if I catch the error and then use RAISERROR to bubble-up the error to .NET app. (I really need to catch the error in my SQL proc and rollback the transaction before I raise the error up to my .NET app...) SQL BEGIN TRYBEGIN TRANSACTION trnName DO MY STUFF.... <---- Error raisedCOMMIT TRANSACTION trnName END TRY BEGIN CATCHROLLBACK TRANSACTION trnName RAISERROR('There was an error',10,1)
END CATCH ASP.NET CODE (No error raised) Try daAdapter.SelectCommand.ExecuteNonQuery()Catch ex As SqlException Err.Raise(50001, "ProcName", "Error:" + ex.Message) End Try
All of a sudden my application started crashing when trying execute dml statements on sql server mobile database (sdf file). Frustating thing is that whole application crashes without any error message. this happens for all kinds for DML statement but not all the time. Sometimes it would fail for delete statement such as delete from table; or for insert into statement
my problem catch does not catch the error. There is no way to find out teh what is causing this error

I create Installer for my company, with using SQL 2005 Express and its files database. I used MS Build bootstrapper before to install MS SQL 2005 Express in my installer and it was installed before my product installed, and there is no problems... But now I need to install Express during setup, because it must be installed NOT everytime (if user choose, in bootstrapper it is impossible). I know that during execute sequence it is not possible: two installer are not lived simultaneously in memory and I move SQL 2005 Express installation to UISequence.
But everytime error occured during install (list from sql server install log): MSI (s) (00:6C) [18:54:38:015]: Machine policy value 'DisableUserInstalls' is 0 MSI (s) (00:6C) [18:54:38:015]: Note: 1: 1309 2: 5 3: c: 3cae475d5363b997aa6d2d8setupsqlncli.msi MSI (s) (00:6C) [18:54:38:015]: MainEngineThread is returning 110 The system cannot open the device or file specified.
So there is no error, "Another installer process in memory", but another very strange error and I dont know what to do :( I try quiet and usual SQL express install - but that doesnt matter.
It seems, that package sqlexpr32.exe after unpacking cant see its files... What must I do to install SQL 2005 Express during my UI of Installer?
Or may some other ways to install SQL 2005 Express, with some secret keys?
I'm running Server 'A' and Server 'B' which are both on SQL 2005 SP2. Server B connects to Server A using the linked server functionality via the SQLNCLI provider. I am issuing an update statement from a web api in a nested transaction that uses a distrubted transaction.
However, I am receiving the following error :
Unable to start a nested transaction for OLE DB provider "SQLNCLI" for linked server "A". A nested transaction was required because the XACT_ABORT option was set to OFF. OLE DB provider "SQLNCLI" for linked server "A" returned message "Cannot start more transactions on this session.".
I've researched the issue and understand how XACT_ABORT works.
Also, I looked at the Linked Server provider options for SQLNCLI and came accross the Nested Queries option being unchecked. I checked the option and applied it to the Linked Server.
Okay, so after my long post my questions are: Do i need to restart SQL in order for this to take effect? If not, what do i need to do? I 've restarted IIS to no avail .
I know blocks and Deadlocks are different but how related are they? Seems like when I get reports of deadlocks I always have blocks and the blocks grow as time passes.
One hack of a way to do it is to run code similar to that which populates the blk column in sp_who; on a job every 5 seconds. It would store the results of code similar to the sp_who output whenever any of the rows has a value greater than zero in the blk column.
This way, I can see what was going on at the time there was a problem. Does anyone have a better strategy for this?
Dear All,we are running SQL2000 Sever and make use of the xp_sendmail.For any reason the mail service can run into problems and it lookslike that the statemnt below gets not finished.EXEC @Status = master..xp_sendmail @recipients=@TOList,@copy_recipients=@CCList,@subject='the subject goeshere',@message=@MailText,@no_output=TRUEUnfortunately the statement is in an update trigger and hence itblocks the table for any further updates.My questions are:Can I achieve a kind of timeout check in my trigger in order to bypassthexp_sendmail call ?In general, sending mail in a trigger may not be a good idea.How can this be solved better ?Any hint is highly welcomeRegardsRolf
I was trying to clean up some conversation in Service Broker and caused alot of blocking that I seem to unable to kill. there was 1 conversation that I was not able to end, so I wanted to restart sql service, But I can't even restart the SQL service. I get the following in Event Viewer
Timeout occurred while waiting for latch: class 'SERVICE_BROKER_TRANSMISSION_INIT', id 00000001A2B03540, type 2, Task 0x0000000000C2EDA8 : 0, waittime 5400, flags 0xa, owning task 0x00000002DEBCA5C8. Continuing to wait.
I've only been doing sql 2005 for a couple of months with minimal training so there's a lot I don't know. What I'm trying to do is load a nested table (industry & customer totals) based on a value from the table it's nested in. This is the relationship of the data. I have at the highest group, an industry code, then a customer, then the part and then the fiscal year. What I'm trying to accomplish is to get a group total (footer) for the (1) industry code and (2) the customer code. This footer would contain the fiscal years (ascending) and their monthly totals. I would like to take the industry code from table one and pass it to the select statement in the dataset that feeds the nested table. I've read this is not possible to load a dataset field into a parm but I've seen where some people know how to work around this. If you reply, please explain in simple terms. Thanks!

When I am running reports on SQL Server 6.5 database which involves creation of temp tables, whole tempdb is locked. All other users are blocked,
The reports involve queries which fetch data into temporary tables, as,
SELECT c1 , c2, c3 ... INTO #tmp1 FROM T1 WHERE C1 = xxx AND .........
When any of these queries are run, it blocks all other operations using TEMPDB, like creation of temporary tables or queries using sorts etc.
It appears that the query locks the system tables (sysobjects, syscolumns) in TEMPDB.
However, the above query works fine if it is constructed as,
CREATE TABLE #tmp1 (a1 ..., a2 ...., a3 ..... )
INSERT INTO #tmp1 SELECT (c1, c2, c3) FROM T1 WHERE c1 = xxx AND .........
Could someone please tell me what actually is happening in the first scenario. Is there a way avoid the blocking of TEMPDB usage other than the workaround mentioned above (which means I have to change all my queries) ?
I'm trying to place records into groups of 100, so I need a query that will return records but not based upon an autonumber type field. For instance, if I had a set of records that had been sequentially numbered (by autonumber) with IDs to greater than 3,600 but there were actually only 300 IDs remaining ranging from 1 to 3600 (say the others were deleted), then I would want to use a query to make three groups of 100 of the remaining IDs.
I can use SELECT TOP 100 for the first 100 records. How do I get subsequent groups of 100?
Hello,we use two instances of the ms sql server 2000 (Version: 8.00.760) on a4 processor windows 2000 (sp 4) machine.A dts-packet on one instance completly blocks the work on the otherinstance. Both instances have 2 dedicated processors. The twoprocessors of the blocked instance are in idle states.How is this possible? Has someone had the same behavior of the sqlserver and found a solution for this problem?Thanks in advance for answersJürgen Simonsen
I wanted to set up a mechanism that would transfer blocks of records (a few dozen to in rare cases a few thousand), with slight modification, from one database to another. It's a sort of custom partial archiving process that would be triggered from a web-based admin application. Records in the target db would be identical except:
-- the primary key in the source table, an identity field, would be just an integer in the target table -- the target table has an extra field, an integer batch ID supplied by the web application that triggers the process
It's a simple, if not efficient matter to do it within the web application: query the source table, suck the records into memory, and insert them one by one into the target db. This will be an infrequent process which can be done at off-hours, so a bit of inefficiency is not the end of the world. But I wondered if there is a more sensible, orthodox approach:
-- Could this process be done, and done efficiently, as a stored procedure with the batch ID passed as a parameter? -- Is there any way to do a bulk insert from a recordset or array in memory using ADO and SQL? And if so, is that better than inserting records one by one?
Advice on the best general approach would be appreciated, and I will try to figure out the details.
I'am relatively new to SSIS-programming and experiencing a serious problem with a package (6618 KB large) containing 5 dataflows. These dataflows all start from a datareader-origin and flow trough multiple transformations. While editing the fifth dataflow the developmentenvironment suddenly became unworkably slow. After any modification made to the dataflow it takes several minutes before I can continue editing. Meanwhile in the task manager the process devenv takes a very large portion (50 to 100%) of CPU.
Building the package,shutting down SSIS and even rebooting the PC don't make any difference. When you close the package ands reopen it, this takes at least 10 minutes.
We work with Microsoft SQL Server Integration Services Designer Version 9.00.1399.00.
Does anyone know if there is a limit to the number of transformations in a flow or the size of a package? Could that be the problem?
Before this problem occured I was multiplying transformations by copying ,renaming and altering them within a dataflow. Could SSIS have some problem with that?
Any suggestion for solving this problem, other than chucking it all away an restarting, will be gratefully accepted.
Somebody tellme that with a format of my database disk with 64K blocks NTFS, i can have better performance, is that true ? there is any problem in SQL with this block size ?
We are working for a long time on optimizing this script, and latest modification I did was splitting script into small blocks and using UNION ALL. This supported a lot but still it takes some 45 mins on prod environment. I'm not able to find anything more in this script to optimize.
I have several stored procedures with a similar query. The SELECT clauses are identical, but the FROM and WHERE clauses are different.
Since the SELECT clause is long and complicated (and often changes), I want to place the SELECT clause in a separate file and then have the stored procedures include the block of text for the SELECT clause when they compile.
Is this possible? Looking through the docs and searching online, I don't see any way to do this.
I have the following SQL that I want to log the number of visits from clients. a session is a block of time, for example, any time between 9-12 is a morning sessions, 12-5 is an afternoon session etc. I need to count the number of sessions in a month not the appointments within the session, make sense?
select sr.resourceid, st.TimeStart, datename(m,sr.scheduledate) as sesmonth, datename(yy,sr.scheduledate) as year, (CASE WHEN DATEPART(hour, st.TimeStart) BETWEEN 0 AND 12 THEN 'MORNING SESSION' WHEN DATEPART(hour, st.TimeStart) BETWEEN 12 AND 17 THEN 'AFTERNOON SESSION' WHEN DATEPART(hour, st.TimeStart) BETWEEN 17 AND 24 THEN 'EVENING SESSION'
Hi. Periodically I need to run a delete statement that deletes old data. The problem is that this can timeout using ODBC (via the CDatabase and CRecordSet classes in legacy code). Also, while its running the delete, the table its operating on is locked and my application can't continue to run and operate on rows not affected by the delete.
Are there any workarounds for this? Can the timeout be set in the connect string?
I've read that microsoft.applicationblocks.data for .net v2 can't be deployed to a mobile app, and my experience bears that out. So I 'm wondering if there are application blocks for windows mobile 5 that would know how to both talk to sql server mobile and sql server 2005. I see OpenNetCF has a port but as far as I can tell, they only address sql server mobile and not talking to a sql server 2005 remote database. I can use the OpenNetCF version for my sql server mobile requirements, but I'm hoping there is an encapsulation of sqlclient calls for communication with my server db.
