Hello all,
I have a script which takes data from a file or MySQL DB, looks up some stuff,
then can print results to console or file. I would also like it to be able to
update a MySQL database with the results. Does anyone have any ideas on how to
do this? I can update records just fine, but what is the best way to do LOTS of
updates aside from running an update statement per record? Using that method,
for example, assuming I have a list of results, each line of the form "ip,fqdn":
for line in inputlist:
updatequery = "update resultstable set fqdn = line.split(",")[1] where
ip = line.split(",")[0];"
connection = MySQLdb.connect(db=self.todatabase, host=self.host,
user=self.user, passwd=self.passwd, port=int(self.port))
cursor = connection.cursor()
cursor.execute(updatequery)
queryresults = cursor.fetchall()
cursor.close()
connection.close()
But this means making a connection and query for every line of results, which
is a lot. Any ideas on optimization?
Thanks,
Sam
