1. Is there any reason why you are using "DCOracle2.execute(dbCursor..."
rather than "dbCursor.execute(..."? You should really be calling teh
cursor's method (assuming the DCOracle2 module follows the DB API
recommendations).

2. Is there any reason why you are using '"2222222222222222",dt)' rather
than '("2222222222222222",dt))' - teh DB PAI suggests execute() should take
two arguments, the first a SQL statement and the second an (optional) tuple
of substitutions.
