Description copied from interface: SQLDataProvider

 Create an iterator over all objects that match the given SQLQuery.
 SQLQuery contains a string representation of SQL 'where' clause.
 The format matches the PreparedStatement format(field1 = ? and field2 > ? and ....).
 The prepared values are accessible by SQLQuery.getPreparedValues() method
 
 Example implementation with SQL PreparedStatement:
 
 
 PreparedStatement st = con.prepareStatement(query.getSelectAllQuery());
 
 int index = 0;
 
 if(query.hasPreparedValues())
 {
        for(Iterator iter = query.getPreparedValues().iterator();iter.hasNext())
        {
                st.setObject(++index,iter.next());
        }
 }
 
 ResultSet rs = st.executeQuery();
 
 return new ResultSetIterator(rs);
 
 

Specified by:

iterator in interface SQLDataProvider

Returns:

a DataIterator or null if no data was found that match the given template

Throws:

DataSourceException
