Обсуждение: BUG #3278: PSQLException when using setBinaryStream via JDBC

The following bug has been logged online:

Bug reference:      3278
Logged by:          jeffrey zhao

Description:        PSQLException when using setBinaryStream via JDBC
Details:

When I run the following program, I got an exception as following:

File file = new File("myimage.gif");
FileInputStream fis = new FileInputStream(file);
PreparedStatement ps = conn.prepareStatement("INSERT INTO images VALUES (?,
?)");
ps.setString(1, file.getName());
ps.setBinaryStream(2, fis, file.length());
ps.executeUpdate();
ps.close();
fis.close();

Exception:

org.postgresql.util.PSQLException: Method
org.postgresql.jdbc4.Jdbc4PreparedStat
ement.setBinaryStream(int, InputStream, long) is not yet implemented.
        at org.postgresql.Driver.notImplemented(Driver.java:728)
        at
org.postgresql.jdbc4.AbstractJdbc4Statement.setBinaryStream(AbstractJ
dbc4Statement.java:70)

Is the method setBinaryStream really not yet implemented?

Thanks.

JDBC4 added a setBinaryStream(int, InputStream, long) method which has not
been implemented yet.  JDBC2 offers setBinaryStream(int, InputStream, int)
which is implmented.  So you'll need to cast the last parameter to an
integer to make it work with the current driver.
