Need help. I am trying to automate error notifications to be sent in mailers. For that I am querying the sysssislog table. I have pasted an "Execute SQl task" on the package event handler "On error". For testing purpose, I am deliberately trying to load duplicate keys in a table which consists of a Primary key column(so as to get an error).

But instead of having just one error, "Violation of primary key constraint", SSIS records 3 in the table. PFA the screenshot as well. How can i restrict the tool to log only one error and not multiple ???

Package Structure.

Package ("On error Event handler") - > DFT -> Oledb Source - > Oledb Destination

 SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80004005.  An OLE DB record is available.  Source: "Microsoft SQL Server Native Client 10.0"  Hresult: 0x80004005  Description: "The statement has been terminated.".  An OLE DB record is available.  Source: "Microsoft SQL Server Native Client 10.0"  Hresult: 0x80004005  Description: "Violation of PRIMARY KEY constraint 'PK_SalesPerson_SalesPersonID'. Cannot insert duplicate key in object 'dbo.SalesPerson'.".  
  SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR.  The "input "OLE DB Destination Input" (56)" failed because error code 0xC020907B occurred, and the error row disposition on "input "OLE DB Destination Input" (56)" specifies failure on error. An error occurred on the specified object of the specified component.  There may be error messages posted before this with more information about the failure.  
  SSIS Error Code DTS_E_PROCESSINPUTFAILED.  The ProcessInput method on component "OLE DB Destination" (43) failed with error code 0xC0209029 while processing input "OLE DB Destination Input" (56). The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.  There may be error messages posted before this with more information about the failure.  

Please guide me. Your help is very much appreciated.

Thanks
