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.

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?
Hi there, Can anyone help me in catching @@error value. I have a stored procedure which return @@error value, I need to read that in my dataaccesslayer and act according to it. how do I catch the return value from stored procedure in my dataaccesslayer. if I am not wrong @@error return a bool value
dear friends i am writng a store procedure to insert into a two table .table 1 data inserted but when i inserting into a table2 it have some error at that time table 1 data also want to delete.give suggestions
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?
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.
is there any way to do sometype of Error handling with in a Stored Proc? Example, If I have a deadlock, can I trap that error and execute other sql code or will always simply kill the stored proc?
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)
1 question: What Error-Handling msut i mplement in a trigger, who is updating permanently two tables in a database (with the follow commands: insert, delete and update) ???
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
I am running some bcp copies through a Sql job. I am copying 35 tables in individual steps. However, sometimes the bcp step fails to copy the data, and I want the step to fail if the data is not copied properly. Is that possible? If so, how? Any help is greatly appreciated.
I have this stored procedure that I need to add error handling to. How would I do that??
REATE PROCEDURE November2000 AS SELECT TM#, LASTNAME, FIRSTNAME, FINALSUITDONE FROM dbo.EmployeeGamingLicense WHERE (FINALSUITDONE BETWEEN CONVERT(DATETIME, '2000-11-01 00:00:00', 102) AND CONVERT(DATETIME, '2000-11-30 00:00:00', 102))
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.
Can i any one help regd error handling while executing stored procedure.
Sample Sequence of execution :
CREATE procedure RBI_Control_sp as begin set nocount on

insert into fin_wh..Status_report([object_name],row,[date]) select 'Data Tranfer','SUCCESS',getdate()
COMMIT TRANSACTION end try
begin catch <b> [i need to insert the type of error in status report table]</b> rollback transaction insert into fin_wh..Status_report([object_name],row,[date]) select 'Data Tranfer','FAILURE',getdate() end catch
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.
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, Password, FirstName, Surname, DateBirth, Email, Id_Country) VALUES( @Username, @Password, @FirstName, @Surname, @DateBirth, @Email, @Id_Country) END TRY BEGIN CATCH
need example on how to add event handling condetion in a package using ssis. my package runs in a loop. the loop creates a connection to diff servers and runs a dynamic query. i want to add a feature which would let the loop run in the event of connection failure for one server.
in analysis services when i proccess a cube i got an error that data from the fact table isnt exists in the dimenstion table for example fact table sales has column suplier that one of its row has data that doesnt match with the dimension table how can i handle this error ? can i insert instead someyhing else so that the proccess can continue and not failed ?
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
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??
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?
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)).
Hello to all I am having a SQLDataSource on my web page to connect with database. Now If it generates any error then where to capture that errors ?? Means at which place(which event or any other place) should i write code for handeling errors ???
I want to load a smallint field with values from a varchar field; e.g. CAST(field as SMALLINT). This is in a bulk copy insert so of course there are the few fields that have '1773A' for example and error out the CAST. Anyone know of a way to return 0 (or 1) if CAST errors on conversion ?
This is the test script that's trying to convert 3750 records (an unknown minority of records contain alpha characters):
create table alstest (field1 smallint) insert into alstest (field1) select CAST(conf_number AS SMALLINT) from conference
I am using dynamica SQL in one of my stored procs That performs BULKINSERT on few tables. If there is a PK constraint violation, I wanted to write an error routine. But once SP_EXECUTESQL gives an error, the stored proc just abends not allowing me to ado anything else. Can anyone help me with some information on how to perform error handling when I am using Dynamic SQL? I am also sending the the piece of code and the error message.
CODE: Assume that all variables are declared appropriately.
IF @error = 0 BEGIN PRINT 'NOW Tb_Manfg GOING TO BE INSERTED.......' EXEC SP_EXECUTESQL @string /* This is where the stored proce abends. The subsequent code is not executed at all. */ PRINT 'ERROR IS.........' PRINT @@ERROR IF @@ERROR = 2627 BEGIN PRINT 'AN ERROR OCCURED WHILE INSERTING INTO Tb_Cateory' SET @error = @@ERROR return END ELSE BEGIN SET @error = @@ERROR END
ERROR MESSAGE: Server: Msg 2627, Level 14, State 1, Line 1 Violation of PRIMARY KEY constraint 'PK__TB_Manfg__1FCDBCEB'. Cannot insert duplicate key in object 'TB_Manfg'. The statement has been terminated.
First Question: I have a script that can run successfully via the Query Analyzer even though it reports a few errors with error number 8152
"Server: Msg 8152, Level 16, State 2, Procedure IndexDensity, Line 85 String or binary data would be truncated. The statement has been terminated."
Why does the script continue to finish in the Query Analyzer but fail immediately when it encounters the same error as a scheduled Job?
Second Question: The serverity is 16 (user managed) so I would like to simply skip over the problem code/row and contiue with the next row to be modified.
How can I handle the error and yet have the script continue when it is scheduled as a job?
Additional Background: I would like to do something like this: If this line...
"SELECT @scan_dnsty = convert(decimal(5,2),RTRIM(substring(density_str, charindex('%',density_str) - 6, 6))) FROM #Density_Out_Tbl"
...generates the error, then simply (skip it and move on to the next row)Fetch the next row.
I have a stored procedure that loops through a customer list and email the customer via xp_sendmail. My problem is that if there is a bad email address, the sproc ends right there.
Is there a way to trap for xp_sendmail errors so my sproc won't fail? I didn't see anything in BOL.
Hi I think by virtue of not being able to find reference to this I have my answer however.... You trap an error, check it and know that you are happy with it - it isn't an issue. Is it possible to prevent that specific error (number, message - the lot) being passed to the client so developers don't need to handle the error a second time? Ta db chucks :D
