A Better Way to Retrieve Row and Column Data

Instead of creating a GridControl to retrieve row and column data from a table into a hash table, use a variant, as shown:
variant = new Variant();
for (row2get=0;
     row2get < queryDataSet1.getColumnCount();
     row2get++) {
  for (column2get=0;
       column2get < queryDataSet1.getColumnCount();
       column2get++) {
         queryDataSet1.getVariant(int row2get, 
           int column2get,variant);
         String bean = (String)variant;
           new String(bean));
You can now cast the data from the variant object to the appropriate type to retrieve the information. This is particularly handy when serializing an object created from a database, since you can ask for the data by column name. You can also use "tiered hash tables" to capture master-detail relationships.
