Parameters

• obj - The OracleBlob object to which the data is copied.

• dst_offset - The offset (in bytes) at which the OracleBlob object is copied.

• cancellationToken - The input cancellation token which can be used by the application to cancel the task.

Return Value

Task<Int64> object representing the asynchronous operation immediately without blocking the calling thread for the whole duration of the query execution.
