DTS And Error Handling For Row Level Constraints
Aug 21, 2000
Please help with a problem - I need to execute the following process:
(1) Create about 200 empty tables in a database (this MUST be done prior to step 2)
(2) copy rows from a source database with identical tables into all of the empty tables,
(3) copy more rows from a third database source (with some duplicate rows) into the tables from step 2.
The problem is that the first copy goes OK since the tables are empty,
but the second copy fails as soon as a duplicate row triggers an error in the DTS tool.
At that point, the DTS tool goes on to the next table until the problem is repeated.
In Oracle, I can set a flag for import such as IGNORE=YES which will ignore object or row creation errors.
How can I get DTS to ignore row creation errors, due to expected duplicate row constraints,
and just carry on with the next row after each rejected row?
In other words, set DTS to simply reject duplicate rows without aborting the entire table copy.
Thanks in advance -

Hello all.
First of all, I've been a reader of swynk.com for quite sometime now, and I'd like to say 'thank you' to everyone who contributes.
Today, I'm the town moron.. haha I'm having issues with column level constraints. I have a varchar(50) where I want to keep *,=,#,/, .. etc, OUT OF the value input. I don't want to strip them. I simply want for sql to throw an error if the insert contains those (and other characters). The only characters that I want in the column are A-Z and 0-9. However, it's not a set number of characters per insert. It always varies... There has to be an easier way to do this than creating a constraint for every possibilty... Any help would be greatly appreciated.
tia,
Jeremy

Developing an application, which is handling encrypting for a SQL server 2005 DB at the application level, using symmetric AES encryption. After being encrypted the data is being sent to the SQL server 2005 DB to be inserted. This is what I want to accomplish. But I have one or two questions as I am going through the research for my project.
Encrypting the data shouldn€™t be that big a deal, but can SQL server 2005 handle to insert these data? If yes how? I am thinking just simple SQL INSERT statements?
When the data are inserted can SQL server, as it supports AES encryption, through the DBMS decrypt the data as they have been encrypted else where and then perform specific functions? (by specific function I just mean any function that may have to run, it could be any function one could think of)
How difficult would it be to take the encrypted data from SQL server to the application and then at the application level decrypt these?
Any help on the above questions is highly appreciated or if people have any comment on the subject I would be more than happy to receive these.
Thank you

Hi,
After reading this helpful blog entry:
http://blogs.msdn.com/sql_protocols/archive/2007/05/13/sql-network-interfaces-error-26-error-locating-server-instance-specified.aspx
I think this might be a good place to ask the following question.
I am writing the error handling code for my data access layer for a web application. I am using the Enterprise Library Data Access Application Block. Although this supports generic database connections, I realized that I need to handle errors specific to each database type. Microsoft SQL is the only database type I am using for now, so I am using a try...catch (SqlException e).
In testing my code, I intentionally changed the instance name in web.config to a name that does not exist. I get the very popular error 26 - Error Locating Server/Instance Specified. This is returned as a SqlException, but the SqlError.Number property is set to -1.
Am I getting "-1" because the provider hasn't actually connected to SQL yet, so it doesn't have an actual SQL error number?
Can I assume that (SqlError.Number == -1) is always a fatal, provider-level connection exception?
Will the provider ever use another SqlError.Number of its own? Or do all numbers besides -1 come from the SQL sysmessages table?.
Is there a comprehensive list of what exceptions might be raised by the SqlClient provider, including #26?
The reason for all the questions is that in a web application, I want to prevent the end-user from seeing the "real" exception if it has to do with configuration errors. However, maybe there are other errors that the user should see and handle? It's hard to know without a full list of SqlClient provider errors, along with the SqlError.Number that each error maps to.
Thanks and regards,
Mark

I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this?
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.

Hi,
I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error.
e.g
MOB 401.908.804 - Fails
0401.907.324 - okay
8239 9082 (pager) - fails
Anyone got an idea on how to fix this????
Regards..
Peter.

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?
AS
SET NOCOUNT ON
DECLARE @Error int;
BEGIN
BEGIN TRY
INSERT INTO Users(
Username,

SELECT @Error = @@ERROR;
IF @Error = 2601
RAISERROR('The username already exists.', 15, 1)
ELSE

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
