    rgalt
    rgalt Feb 27, 2006 12:08 PM

      Hallo,

      my entity has an BLOB (MSSQL Server TEXT datatype). After storing I will execute the refresh() Methode of the entity manager.

      I get the following error:
      INFO [STDOUT] org.hibernate.exception.GenericJDBCException: could not load an entity: [de.orgacard.ejb.entity.Participant#21662]

      In the mircorsoft knowledge base I found the following article
      http://support.microsoft.com/default.aspx?scid=kb;en-us;824106

      This error occurs with ResultSet objects that contain a BLOB column (for example, text, ntext, or image data types). The driver cannot return a BLOB column out of order because it does not cache all the content of BLOB data types because of size limitations.
      For any row in the ResultSet, you can read any column from left to right, and each column should be read only one time. If you try to read columns out of order, or if you re-read a column from the ResultSet, you may receive the error message that the "Symptoms" section describes.
      To prevent the problem, read the ResultSet columns in order.

      What can I do?

      Thanks
      Ralf
