What I have been doing in my custom tags could also apply to any query
output situation. The following is in lieu of declaring your query
TYPE_SCROLL_INSENSITIVE and then calling myquery.first() to reset the
cursor back to the first row.
//Create an ArrayList Of HashMaps
ArrayList rows = new ArrayList();
HashMap columns = null
//as you output the query the first time also add it to the above
structures.
while(myquery.next()){
columns = new HashMap();
colums.put("column_name1",myquery.getObject(1));
colums.put("column_name2",myquery.getObject(2));
//........... and so on.
// add the columns to a row
rows.add(columns)
}
// then loop through your structure like so.
rowIter = rows.iterator();
while(rowIter.hasNext()){
columns = rowIter.next();
thismap.get("column_name1");
thismap.get("column_name2");
}
//.......... and so on.
