Hi all,
sometimes I have problems in updating a CLOB field on table in my database, becasue the SQL command is too long. This depends on the fact that the value that I have to save can be very long.

    
private String createSQLUpdateOrder(String idComm, String commission, String xmlOrder) {
    return "UPDATE MyTable "
        + "SET CLOBField='" + xmlOrder + "' "
        + "WHERE OrderId='" + idComm + "' And Order='" + commission + "')";
  }

public boolean saveOrderInformation(String xmlOrder, String commission, String idComm) {
    int retval = 0;

    try {
      retval = SERVICES.getService(EDICCSqlService.class).update(createSQLUpdateOrder(idComm, commission, xmlOrder));
    }
    catch (ProcessingException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
      System.out.println(e.getMessage());
      retval = -1;
    }
  }


Probably I manage this kind of information in incorrectly way. Anyone has any suggestions?

Thanks in advance for your help

You should consider using binds in the SQL:

private String createSQLUpdateOrder() {
        return "UPDATE MyTable "
            + "SET CLOBField=:xmlOrderBind "
            + "WHERE OrderId=:idCommBind And Order=:commissionBind)";
      }

    public boolean saveOrderInformation(String xmlOrder, String commission, String idComm) {
        int retval = 0;

        try {
          retval = SERVICES.getService(EDICCSqlService.class).update(
                           createSQLUpdateOrder(),
                           new NVPair("xmlOrderBind", xmlOrder),
                           new NVPair("idCommBind", idComm),
                           new NVPair("commissionBind", commission)
                           );
        }
        catch (ProcessingException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
          System.out.println(e.getMessage());
          retval = -1;
        }
      }


It is possible that this good practice solve your problem. Let me know.

Hi Jeremie,

Used code is:

    int retval = 0;

    try {
      retval = SERVICES.getService(EDICCSqlService.class).update(
          createSQLUpdateOrder(),
          new NVPair("xmlOrderBind", xmlOrder1),

What are you import for NVPair?

It should be:
org.eclipse.scout.commons.holders.NVPair

Now it works. Thanks
