TypeError: unsupported operand type(s) for %: 'long' and 'str'

Question

With this code:

current_time=time.localtime()
time_now=time.strftime('%H:%M:%S',current_time)

cursor.execute("Select * from SUBSCRIPTION_DETAILS where Alert_time='%s'") % time_now

I get the error:

unsupported operand type(s) for %:long and str

type of Alert_time is varchar

Answer 1

You misplaced your %

What you're doing now is:

cursor.execute("[snip]") % time_now

So you're applying time_now on the result of cursor.execute

What you want is use the % with the string, like so:

cursor.execute("[snip]" % time_now)

BUT don't do this, you should use:

cursor.execute("Select * from SUBSCRIPTION_DETAILS where Alert_time=%s", (time_now,))

Note that here, we're passing time_now as a second parameter, instead of using the % operator. This will make sure the query is properly sanitized, to prevent SQL injection attacks.

The (somewhat ugly) trailing , is needed to make sure the second argument is a tuple.
