Dear folks,
I find yet again that I am confused by what I read in pep-0249.
This time it is the last line describing the attribute of cursor objects
named .arraysize (I quote here both paragraphs):
This read/write attribute specifies the number of rows to
fetch at a time with fetchmany(). It defaults to 1 meaning
to fetch a single row at a time.
Implementations must observe this value with respect to
the fetchmany() method, but are free to interact with the
database a single row at a time. It may also be used in
the implementation of executemany().
I fail to grasp how .arraysize could have any bearing on .executemany()
or for that matter any operation other than fetchmany(). Thus I find I
must request aid in understanding what the intent is here - HELP, please.
While I am bothering you good people with my silly questions, I
might just as well tack on another: if one invokes .executemany with a
seq_of_parameters that is empty (like
a_cursor.executemany(SQL, [])
) shouldn't the interface module execute the query zero times, ie, not
execute the query at all?
I think that is what I am going to do but I would like to hear your
comments either way.
Thank you all,
Arthur Protin
