OdbcCommand.Cancel Method

Tries to cancel the execution of an OdbcCommand.

Namespace:  System.Data.Odbc
Assembly:  System.Data (in System.Data.dll)

public override void Cancel()

Implements

IDbCommand.Cancel()

If there is nothing to cancel, nothing occurs. However, if there is a command in process, and the cancellation try fails, no exception is generated.

To cancel a query on one thread, Cancel must be called from another thread. Because you cannot execute commands asynchronously with OdbcCommand, to cancel a command from another thread, one thread must be running synchronously. This means that the OdbcCommand object must be accessible from both threads.
