Error Handling And Problem Resolution
Oct 28, 2007
I posted a question a few days ago, to get some general information what this command does:
command.cmd
osql -S (local)SQLEXPRESS -E -i DropDB.sql
DropDB.sql
IF EXISTS (SELECT name FROM sys.databases WHERE name = N'Caching')
DROP DATABASE [Caching]
I have gotten some great answers. Now I like to ask a deeper question. This command was created for SQL Server Express, for an internal software package at my company, by an outside vendor. However, sometimes this command doesn't work 100% on all user computers. So I have two questions.
1. Is there any way to either enhance the command, or the database command, to provide error diagnostics, to find out the issue for an individual user computer, why it doesn't always work?
2. Can anyone think of any scenarios that would prevent this from working?
The key element here is that this caching database is supposed to allow individuals to use a particular piece of software, when they aren't connected to the network at work. But it doesn't always work on each computer - 100% of the time - even when the computer has SQL Server Express installed, and is running Windows XP.

An outside vendor created this command and SQL files for internal
software, using SQL Server Express, which is installed on every user
machine
osql -S (local)SQLEXPRESS -E -i DropDB.sql
The SQL file has this:
IF EXISTS (SELECT name FROM sys.databases WHERE name = N'Caching')
DROP DATABASE [Caching]

I am using Allwayson to replicate a FCI to a remote site. (windows 2012R2) Although all is implemented, iam getting a strange error with the listener resources after ive made a failover test.
It keeps saying "Name resolution not yet available"from my understanding this is trying to update an entry that doesn't exist (since the user has permissions to do it).

Hi SQL Server Team,
In order to add a data source by using ODBC Administrator, programmatically i am using SQLConfigDataSource. Thus calling SQLConfigDataSource with the fOption set to either ODBC_ADD_DSN for creating a new DSN.
Following is the stattement specified in the source code. where type_of_driver = "Microsoft Access Driver (*.mdb)"; and parameters contains the data source source credentials information such as DSN, UID, PSW, FIL, Description, DataDirectory,DEFAULTDIR and DBQ all separated by " ".
rc = SQLConfigDataSource(NULL, ODBC_ADD_DSN, type_of_driver, parameters);
after execution of below mentioned command an error is encountered i.e -1 is returned if the DataDirectory path exceeds certain nested directories link. for eg. the file path specified below.
C:My DocumentsClients CurrentAHW Netcare BenefitsDeliverables1-5 Results Chain - system LevelAlberta NetcareBenefits Logic System Level V01.rcm
Creating a datasource with the file name i.e Benefits Logic System Level V01 every time.
rc = :: SQLConnect(hDbc, (unsigned char *)szSource, SQL_NTS, (unsigned char *)szUserName, SQL_NTS, (unsigned char *)szPassword, SQL_NTS);
Also following error message was encountered during execution of SQLConnect command.
/*szErrorMsg = 0x0012e834 "[Microsoft][ODBC Microsoft Access Driver]General error Not enough information to connect to this DSN with SQLConnect. Use SQLDriverConnect."*/
Thus followed the instruction smentioned in the error message an dtried using SQL DriverConnect() in the following manner.
rc = :: SQLDriverConnect(hDbc, NULL,(SQLCHAR *)"DSN=RCM",SQL_NTS,outstr, sizeof(outstr),
&outstrlen,SQL_DRIVER_NOPROMPT);
Still an error is encountered but this time it returns a RETCODE of 100 whrease earlier it had returned -1.
Inform the procedure to be followed using SQLConnect when DataDirectory path is too long.
An early reply will be appreciated.
Cheers & Regards,
Saresh

Hello,
I would like to supress an Informational error that SQL is returning when I run a stored proc that I created. The error message returned is:
Warning: Null value eliminated from aggregate.
The values returned from the stored proc are the results from a 'select * from #tmp_tbl". Before returning the values, I simply create the temp table, populate it and then run the select statement. Prior to getting my results, I get the error message. Can I suppress it and how?
Thank you.

I am writing a stored procedure that loads transaction logs to a database and I am having trouble trapping meaningful error messages. When ever the load fails, it gives me two error messages, the first one is meaningful and the second one just states that the load ended abnormally. Unforunately, when I capture the error using @@error after the load statement, it is the second error message that I am getting.
Is there anyway to trap the first error message as well?
Thanks

I currently have defined a source server, a transformation, and a destination server using DTS. How and where do I create an error routine that would capture any and all errors that would occur. This would include connection error, transformation errors etc. I know the errors can be written out to a text file but I would like them written to a table on my destination server.
The DTS package will be called from an external program using the xp_cmdshell extended stored procedure. We are using it this way as a flag so if one transformation fails it will return a 1. If all are successful it will return a O. These will be our flags to check the errors table in the destination server.
Could someone tell me where this code is to go and what the code will look like. Samples would be the most help.
Thanks
Tom

I have a composite unique key on the audit_hub table that includes TimeStamp, UID, Type, Mailbox all as part of the unique key.
I’m trying to do inserts, and know that in some cases I will violate unique index.
I’m using stored procedure, and want to handle the error gracefully there – just move on.
Reading from text-based log files via .vbs and get back the nasty popup window.
Looks like I have it right but obviously I don’t considering how it’s (not) working.
I thought error handling would be the simplest way to avoid dupe records. Might be necessary to run the same log in more than once, and only want to add the new records since the last insert session.
Here’s what I have. It obviously simply halts and complains immediately after the insert attempt.
ALTER procedure eml_HubInsert
@TimeStamp bigint
,@UID varchar(255)
,@Type varchar(255)
,@MailBox varchar(255)
,@ServerID varchar(50)
as
insert into audit_hub (TimeStamp,UID,Type,Mailbox,ServerID)
values (@TimeStamp,@UID,@Type,@MailBox,@ServerID)
if @@ERROR = 2601
begin
return 0
end

I have some stored procedures that insert information from a third party plugin that hooks into our database (so I can't do any client side validiation). The problem I am encountering is that some of the fields I use need to be in DateTime format. In order for SQL SERVER 2000 to be able to insert this field, the Date has to be in the correct syntax or an error is thrown.
Is there any way to do something like this in SQL SERVER 2000
Code:
DELCARE @SomeDate DateTime
Try
Set @SomeDate = CONVERT(DateTime, Parameter1, 101)
Catch
return custom error describing what field is formatted
wrong and exit stored procedure
END

ppl,
i wrote this sql, seems v.straightforward to me.
It works first time round, sets the foreigh key, but second time round should error out to the handler - but it just reports the errors to the message out and dosn't seem to fire the errhandler.
Its gotta be a simple mistake - perhaps you could show me.
DECLARE @ErrorMsg int
BEGIN TRANSACTION
ALTER TABLE TPH_GlobalProductHierarchy
ADD CONSTRAINT SalesSubGrp_fk FOREIGN KEY (SalesSubGroupingID)
REFERENCES TPH_SalesSubGrouping (ID)
SET @ErrorMsg =@@ERROR
IF @ErrorMsg <>0 GOTO ErrorHandler
PRINT 'Success'
COMMIT TRANSACTION
ErrorHandler:
IF @ErrorMsg <> 0
BEGIN
PRINT 'Rollback'
ROLLBACK TRANSACTION

Hi all,
I am calling some stored procedures from ASP. These strored procedures have to deal with lots of deletes and updates. So i have thought of implementing transaction commits and rollbacks. But if a rollback occurs in these stored procedures, i want to get a value back to asp page, based on this value i will run the next stored procedure.
Can anybody give me some examples for doing this.
Somebody please help me with this!!!!!!!!!
Thanks a lot in advance,

hello. below is a very simple SP i have coded to insert a user into my database. i have created a unique index for the username column on my database table. if the username already i want to convey this to my C# code which is attempting the insert. i am using a combination of TRY/CATCH, RAISERROR and @@ERROR here to achieve my aim. could somebody please look at my code and tell me if the error handling code is OK, or is it overly complicated?

I have a stored procedure that inserts a new record into a table. The table it inserts into has a unique constraint that utilizes an identity column. Occassionally, this constraint gets violated due to the fact that the app running my stored procedure isn't the only application inserting into the table. Ideally, we would want to change the design to avoid this scenario but these are legacy applications that will eventually be sunsetted. My question is this; is there a way to handle the unique key constraint violation and prevent an exception being thrown in the app calling the stored proc? I know I can check for the error code and handle it within the stored proc but my app still gets an exception caught by the calling method. Can I prevent this from happening? I want for the insert to attempt again and if successful continue processing and not produce the exception. Any help would be greatly appreciated.

Hi,
I'm trying to decide on the best method for dealing with errors in a DTS package. It is sufficient to retrieve Step failure information after package execution but I have tried both methods. Specifically, these methods are detailed in http://support.microsoft.com/kb/240221. Another article - http://support.microsoft.com/default.aspx?scid=kb;en-us;321525 - details the need to establish a single event sink to avoid "unexpected behaviour". I have used the code as described but noticed very little difference between post execution checking using GetExecutionErrorInfo and the PackageEventSink Interface. Using the Event Sink does retrieve one extra type of error, ie.
"Error at Destination for Row number 2. Errors encountered so far in this task: 1". This error will always give the row number as the last row in the file, in this case an excel file source. This is not really useful, but I don't want to detach the Event Sink because of the possibility of "unexpected behaviour". Could somebody advise? First is it possible to retrieve the line number, and secondly can anyone detail what an example of this unexpected behaviour might be? Finally, is there a way to retrieve a unique key constraint violation from a package if it occurs? It is only caught in the generalised way and produced as "Error at Destination...".
Thanks in advance

Hello,
I'm mainly a .net dev and now I want to create a TV function using the CLR inside SQL Server but I have some doubt about the error handling in the function itself and in t-sql.
I have a SP (that I suppose will have a BEGIN TRY ... END TRY BEGIN CATCH ...END CATCH) that call my TV function to get a table made of one row and 2 columns.
My TV function calls some private functions that uses .net classes so I want to handle the exception the potentially could happens.
But these expection shouldn't thrown the error to the caller SP because the SP must continue iven if there is a error but I would to inform somehow the SP that the fields in the table are null because something went wrong
What is the programming pattern to use?
If I write
<Microsoft.SqlServer.Server.SqlFunction(DataAccess:=DataAccessKind.None, FillRowMethodName:="FillDatesRow", isDeterministic:=True, Name:="GetDates", TableDefinition:="StartDate datetime,EndDate datetime")> _
Public Shared Function GetDates(ByVal UTCInputDate As Date) As IEnumerable
Dim StartDate As Date
Dim EndDate As Date
Dim rowArray As ArrayList = New ArrayList
Try
Dim GetDates (1) As Object
GetDates = Function1(UTCInputDate) 'Function that can cause exception directly or indirectly
GetDates (0) = StartDate
GetDates (0) = EndDate
rowArray.Add(GetDates)
Catch ex As Exception
????
End Try
Return rowArray
End Function
Private Shared Sub FillDatesRow(ByVal obj As Object, <Out()> ByRef StartDate As SqlDateTime, <Out()> ByRef EndDate As SqlDateTime)
Try
If obj IsNot Nothing Then
Dim row As Object() = CType(obj, Object())
If row(0) IsNot Nothing Then
StartDate = CType(row(0), DateTime)
Else
StartDate = SqlDateTime.Null
End If
If row(0) IsNot Nothing Then
EndDate = CType(row(1), DateTime)
Else
EndDate = SqlDateTime.Null
End If
Else
StartDate = SqlDateTime.Null
EndDate = SqlDateTime.Null
End If
Catch ex As Exception
Throw
End Try
End Sub
What I have to write in the GetDates' s catch block to avoid that the exception is thrown to the BEGIN CATCH END CATCH of the caller SP but inform anyway the caller??
Any tips and/or resources is welcome!
Thankx

Hey,
My flow is build with in the beginning an sql command in an OLE DB source, this command I use to create an incremental update which works faster than an SCD task.
Now when I debug the package runs but stops after a short time. One control flow with that sql statements rus perfectly but the other gives an error.
The errors I get are:
- [OLE DB Source 1 [2946]] Error: The attempt to add a row to the Data Flow task buffer failed with error code 0xC0047020.
- [DTS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. The PrimeOutput method on component "OLE DB Source 1" (2946) returned error code 0xC02020C4. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing. There may be error messages posted before this with more information about the failure.
The dataflow task starts with that sql statement where afterwords I do a data conversion and then I store it in with an OLE DB destination in a table.
Now i don't know why one statement works while the other isn't working...
Does anyone has an idea?
Thanx

Hey,Here's yet another question for you more knowledgeable than me Up to this point I have been using a try/catch statement when dealing with SQL, for exampleint result = 0;try{result = Int32.Parse(command.ExecuteScalar().ToString());}catch{result = 0;}But I read up one some error handling and I have no idea how to solve this anymore. Since I'll be using the catch block to catch exceptions, something like thiscatch (SqlException){throw;}So I was wondering what is the good, standard practice for dealing with this since I need the catch statement to set result to zero or I would end up with an error.Thanks in advance,Sixten

I am building a Bulk Insert statement dynamically passing in filename location, etc.
I have coded error handling via the @@ERROR. To test the error handling, I am forcing the file that is bulk inserted to be missing.
The statement is created in a declared variable, IE @SQL:
EXEC(@SQL)
IF @@ERROR <> 0
BEGIN
GOTO ErrorHandler
END
Since the file is missing it causes an error, and the Stored Procedure gives the
Server: Msg 4860, Level 16, State 1, Line 1 Could not find the file etc.
and aborts aborts the whole stored proc at that point. In other words the error handling IF @@ERROR doesn't trap the error and send the process to the error handler routine.
Is there anyway to get the error back from the EXEC, or maybe something has to be set to trap the error because it is fatal? Because of the way the Bulk Insert statement is created dynamically, it appears you have to EXEC the statement once it is built (EXEC(@SQL)).
Any help would be appreciated.
