Hello everyone,
 My developers at our shop have issues with learning new stuff. When i say "new", i really mean old... Implicit cursors haven't even been discovered by them yet. Anyways, what would be a good way of having a cursor, trying to find out if there's anything in it, doing one specific thing if there is, then loop and doing same thing over and over?  Here's current code/way of doing it:
 OPEN inv_data;
 FETCH inv_data INTO inv_rec;
 IF inv_data%FOUND
 v_file :=
 sys.utl_file.fopen(location => 'SPEMETALS_OUT_DIR'
,filename => v_inv_import_file
,open_mode => 'w');

 sys.utl_file.put_line(v_file, 'wt' || ',' || 'pcs' <snip, just writing a "header" line in the file>
 || 'a_item'
 || ','
 || 'a_type');


 sys.utl_file.put_line(v_file, inv_rec.wt || ',' || inv_rec.pcs <snip, writing out all the rows from the cursor to the file>

 || inv_rec.a_item
 || ','
 || inv_rec.a_type);

 FETCH inv_data INTO inv_rec;
 END LOOP;  sys.utl_file.fclose(v_file);
 CLOSE inv_data;

 Can I use an EXCEPTION Clause? Is the above the best way to do it, with Explicit cursors?
