This setBinaryStream method is specified by the setBinaryStream method in the java.sql.Blob interface.
Data in the BLOB is overwritten by the output stream starting at the specified position and can over-run the initial length of the BLOB. Specifying a position+1 value will append bytes. Passing a position+2 or greater (or zero or less) value will cause a position error to be thrown.
