Records from multiple tables

Question

Hi,
I have a method that has to access records from multiple tables and store them all in a file. It's something like this:
switch (tableId){
case 'A' : query="SELECT * FROM TABLE_A
WHERE ID = '" + tempId + "'";
ResultSet rs = stmt.executeQuery (query);
rs.close();
break;
case 'B' : query="SELECT * FROM TABLE_B
WHERE ID = '" + tempId + "'";
rs = stmt.executeQuery (query);
rs.close();
break;
case 'C' : query="SELECT * FROM TABLE_C
WHERE ID = '" + tempId + "'";
rs = stmt.executeQuery (query);
rs.close();
break;
My problem is that I get an "Invalid cursor" error the second time I enter the loop. I've been reading up on cursors but I still don't know what to do. Can I use ResultSet to return multiple rows from multiple tables? If not, what can I use? Please help!
Thanks in advance.

Answer 1

remove the "rs.close()" from the switch statement. use "rs.close()" after your loop ends.
