Ms Access Odbc Error Trapping

from ODBC. Some of them are cryptic even to developers, let alone end users. They are also notoriously difficult to handle. ms access vba error handling For bound forms the Form_Error event gives very little information. For unbound vba error handling examples scenarios the Errors collection is better, but you are still stuck with cryptic messages. In this blog post we vba error handling best practices will present an integrated way to deal with ODBC errors: how to intercept them and how to transform them into user-friendly messages. The details are interesting and somewhat complex, but
Ms Access Error Handling Best Practice
abstracted away for those developers who just want to get things done. 2 lines of code are all that it takes. Example Here is an example of such message. Using the database and Access client application in the download package I copied the "Row Guid" value from the first record into the second record and saved it: The text on microsoft access #error this message is: ODBC--call failed. [Microsoft][SQL Server Native Client 11.0][SQL Server]Violation of UNIQUE KEY constraint 'AK_SalesOrderHeader_rowguid'. Cannot insert duplicate key in object 'SalesLT.SalesOrderHeader'. The duplicate key value is (b3339719-1b0f-4ad0-a2e4-d1d6e5e6e22b). (#2627) [Microsoft][SQL Server Native Client 11.0][SQL Server]The statement has been terminated. (#3621) The error occurs because saving the record violates a database rule that says that the values in the rowguid field must be unique. Of course we should use best practices to ensure that we minimize errors like this from occurring. In this case the rowguid field would probably not even be on our form. In many cases we can check for upcoming violations before the record is saved, for example in the Form_BeforeUpdate event. But that still leaves the errors that fall between the cracks or that we simply did not want to check for because it would be too expensive. We typically don't want to repeat all database logic in our application. Often it is better to let the error happen and handle it gracefully.

I'm getting an error and popup windows, presumably from the ODBC Driver? I want to suppress these and handle vba error handling the error myself. I know about the DAO.errors and ADO.errors collections but these don't help if I can't get the error to call my error handler! The code below will give the error (unless you happen to have a table called myTable in a database called myDatabase on a server called myServer). I've tried to use ADODB rather than DAO but could not get this to work at all. Any ideas? Public Function main() Dim myDB As DAO.Database Dim myTabledef As DAO.TableDef On Error GoTo Err_handler Set myDB = CurrentDb Set myTabledef = myDB.CreateTableDef("l_table") DoCmd.SetWarnings False myTabledef.Connect = "odbc;driver=SqLServer;" & _ "DATABASE=myDB;SERVER=myServer;Trusted_Connection=Yes;" myTabledef.SourceTableName = "MyTable" myDB.TableDefs.Append myTabledef DoCmd.SetWarnings True Exit Function Err_handler: MsgBox Err.Number & " - " & Err.Description End Function I made a mistake in the posted code {Sql Server} became SqLServer when I posted it. So the full code that gives the error is below: Public Function main() Dim myDB As DAO.Database Dim myTabledef As DAO.TableDef On Error GoTo Err_handler Set myDB = CurrentDb Set myTabledef = myDB.CreateTableDef("l_table") DoCmd.SetWarnings False myTabledef.Connect = "odbc;driver={Sql Serv
