[DB-SIG] PEP 249

[Konjkov Vladimir]

in definition of
.execute(operation[,parameters])
.....
A reference to the operation will be retained by the
cursor. If the same operation object is passed in again,
then the cursor can optimize its behavior.

What meens "the same operation object is passed in again"?
There's no definition for Class Operation.

May by it meens

SameOperation = "something that just a constant!"
C = cnxn.cursor()
C.execute("select * from table where a=? and b=?",(1,2))
C.fetchall()
C.execute(SameOperation,(3,4))
C.fetchall()

or not?
