Stream Class
You use a Stream to read or write streamed data (usually LONG).
Stream Class
■ A read-able stream is used to obtain streamed data from a result set or OUT
bind variable from a stored procedure call. A read-able stream must be read
completely until the end of data is reached or it should be closed to discard any
unwanted data.
■ A write-able stream is used to provide streamed data (usually LONG) to
parameterized statements including callable statements.
