public final class BlobIOException

extends IOException

An exception has occurred while operating on a blob stream.

The driver maintains the stream by requesting network segments when needed, managing blob requests against other JDBC requests, converting stream data encodings, and flushing the blob stream when necessary.

A variety of SQLExceptions, or IOExceptions could occur within the driver during a user-requested operation on a blob stream, but all exceptions are surfaced to the user of the stream as a java IOException, because the user is operating on a java.io.InputStream which is not distinguished as a blob stream as part of the JDBC API.

Here are some typical reasons for a BlobIOException

• Any SQLException, such as a RemoteProtocolException or CommunicationException thrown during a close(), read(), or skip() on the stream would result in a BlobIOException being thrown for that operation.
• An attempt was made to read() or skip() on a stream which is closed.
• A call made to reset will result in a BlobIOException because mark() is not supported on blob streams.
• An improper blob data encoding was detected while reading from stream.
