Remarks

In DbDataAdapter, this method throws NotSupportedException. Classes that inherit from DbDataAdapter override this method to provide support for batches.

Notes to Inheritors

This method is protected and is designed for use by a .NET Framework data provider.

If a class that inherits from DbDataAdapter supports batches, that class overrides this method to allow users to execute a batch. An implementation uses the commandIdentifier provided to locate the requested command, then uses the parameterIndex provided to locate the requested parameter. For example, a commandIdentifier of 0 and a parameterIndex of 0 returns the first parameter from the first command in the batch.
