public abstract InputStream getBinaryStream( String columnName ) throws SQLException
Parameters
- columnName
- is the SQL name of the column
Returns
a Java input stream that delivers the database column value
as a stream of uninterpreted bytes. If the value is SQL NULL
then the result is null.
Description
A column value can be retrieved as a stream of uninterpreted bytes
and then read in chunks from the stream. This method is particularly
suitable for retrieving large LONGVARBINARY values.
Note: All the data in the returned stream must
be read prior to getting the value of any other column. The
next call to a get method implicitly closes the stream.
Exceptions
SQLException
if a database-access error occurs.
