Okay, it must be a slow brain week for me. After looking at some
driver code I see that I completely missed the point about what NUMBER,
DATETIME, etc are used for.
My basic question was if I had a real or numeric field in my database,
how do I tell the driver that it needs to send that. The answer is as
before, let the drive handle that:
cursor.execute("INSERT INTO mytable (my_id, my_real, my_date) VALUES
(%s, %s, %s)",
(2, 10.2, "now"))
cursor.execute("SELECT my_real, my_date) FROM mytable WHERE my_id = 2")
fetchedL = cursor.fetchone()
[10.199999999999999, '2004-02-13 10:05:57.343744']
if type(clist) == pgdb.FLOAT:
print "First argument is a pgdb FLOAT"
if type(clist) == float:
print "First argument is a python float"
Only print's that this is a python float.
When would one use something like pgdb.FLOAT?
