Error description

  • After installing the the DB2 v. 9.7 FP5 the DB2DataAdapter will
    throw DB2Exception when updating a DataTable which contains an
    updated row with assigned new values the same as the original
    values (DataRowVersion.Original).
    
    Example .NET:
    
    Assume:  table T_TEST has column TESTVAL and only 1 row with
    value "test1"
    
                DB2DataAdapter adapter = new DB2DataAdapter();
                adapter.SelectCommand = new DB2Command("select *
    from t_test",db2Conn);
                DataSet ds = new DataSet();
                adapter.Fill(ds);
    
                DB2CommandBuilder db2cb = new
    DB2CommandBuilder(adapter);
                DataRow row = ds.Tables[0].Rows[0];
                row["TESTVAL"] = "test1";
    
                adapter.Update(ds);
    
    The eecution of adapter.Update(ds) will result in DB2Exception
    with message:
    
    ERROR [22540] [IBM][DB2/NT] SQL20434N  An update operation
    hasset all of its target columns to unassigned
