  The following read/write methods are not supported for opaque types:

  • readString()

    Use the Informix extension readBytes(len).

  • readCharacterStream()
  • readAsciiStream()
  • readBinaryStream()
  • readObject()
  • readRef()
  • readArray()
• java.sql.SQLOutput

  The following read/write methods are not supported for opaque types:
