[Tutor] Help with a SQL Statement
Hi All,
The SQL statement below doesn't return anything.. and I don't know why...
I've used the parans but still no luck. Any Suggestions?
cur.execute("""select badge, name, stage, tc, major, package, subject,
course, sb_as from records where
sb_as = 0 and (subject like 'Workshop&' or subject like
'Basic%' or subject like 'Introduction%') and
(major not like 'Customer%' or major not like
'Warehouse%') order by tc""")
Thanks

Re: [Tutor] Help with a SQL Statement
Hi, I found one typo in 'Workshop&' which should be 'Workshop%' but it
still gives results containing majors with 'Customer%' and 'Warehouse%' in
them...

This is not a python issue, but shouldn't the last part of your where
clause be "major not like 'Customer%' and major not like 'Warehouse%'"
?

I'll restructure it to how I think you want it...
cur.execute("""
select badge, name, stage, tc, major, package, subject, course, sb_as
from records
where
sb_as = 0 and
(subject like 'Workshop&') or
(subject like 'Basic%') or
(subject like 'Introduction%') and
(major not like 'Customer%') or
(major not like 'Warehouse%')
order by tc""")
See if that helps... I think your parens were grouping the wrong things.

Occasionally, it'll happen to be right. Rather than returning the first value that's equal, you'd have to return the lowest value that's equal. -- DaveA ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Usually email providers have particular ports and types of encryption that
must be specified to authenticate before you can DL an entire inbox or send
a message from the address.

Re: [Tutor] sending email via smtplib
I don't think using SSL works with hotmail. I tried using:
smtplib.*SMTP_SSL*("smtp.live.com", 587)
smtplib.login(user, passwd)
...
That gave this error:
Traceback (most recent call last):
