Your application must be designed to handle any errors that occur, including ADO.NET errors. ADO.NET errors are handled within your code in the same way that you handle other errors in your application.
The SQL Anywhere .NET Data Provider creates an SAException object and throws an exception whenever errors occur during execution. Each SAException object consists of a list of SAError objects, and these error objects include the error message and code.
Errors are different from conflicts. Conflicts arise when changes are applied to the database. Your application should include a process to compute correct values or to log conflicts when they arise.
