Example 3 with HsqlByteArrayOutputStream

use of org.hsqldb_voltpatches.lib.HsqlByteArrayOutputStream in project voltdb by VoltDB.

the class JDBCPreparedStatement method setBinaryStream.

     * Sets the designated parameter to the given input stream, which will have

     * stream as needed until end-of-file is reached.
     *
     * <P><B>Note:</B> This stream object can either be a standard
     * Java stream object or your own subclass that implements the
     * standard interface.
     *
     * @param parameterIndex the first parameter is 1, the second is 2, ...
     * @param x the java input stream which contains the binary parameter value
     * @param length the number of bytes in the stream
