Alias querySequence
Execute a one-off SQL SELECT command where you want to deal with the result set one row at a time.
If you need random access to the resulting Row elements,
simply call std
on the result.
If the SQL command does not produce a result set (such as INSERT/CREATE/etc),
then mysql will be thrown. Use
exec instead for such commands.
Use this method when you are not going to be using the same command
repeatedly and you are CERTAIN all the data you're sending is properly
escaped. Otherwise consider using mysql.
If there are long data items among the expected result columns you can use the csa param to specify that they are to be subject to chunked transfer via a delegate.
