Working with recordsets

[chema.rey]

Hi.

I have one recorset that I would like to pass to 2 functions, one is
for create an CSV file and the other one is to create a HTML file. The
problem is that the recordset is totally read in the first function,
and then when I pass it to the second funtion the recordset is in the
last record.

I've read docs, but I think that one cursor doesn't have something
like movefirst() method. Anybody have an idea to solve this?

Thank's.

Try loading the whole recordset with the fetchall() method and use the
resulting sequence in your functions. It won't be memory-efficient but
it will be easy to do.

Or, if this doesn't suit, try creating two separate cursors from the
same connection and execute the same query on each. There's some chance
that your database driver/backend combination will optimize the queries
then.
