C++
virtual EUpdateError* __fastcall PSGetUpdateException(System::Sysutils::Exception* E, EUpdateError* Prev);
Description
Generates an EUpdateError object based on another exception object.
The provider component calls PSGetUpdateException when the exception E occurs while applying updates. This method allows the provider to create a single EUpdateError object that encapsulates all the exceptions that occur in an update operation.
PSGetUpdateException determines the error message, context string, and error code from the exception specified by E and creates a new EUpdateError exception that includes that information as well as the information about a previous error, as specified by Prev. The context string and error code for E may be specific to the Exception class associated with the dataset. By default, TDataSet generates an EUpdateError with an error code of 1 and an empty context string.
This method is an implementation of IProviderSupport.PSGetUpdateException.
