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(",") where ip = line.split(",");"
connection = MySQLdb.connect(db=self.todatabase, host=self.host,
user=self.user, passwd=self.passwd, port=int(self.port))
cursor = connection.cursor()
queryresults = cursor.fetchall()
But this means making a connection and query for every line of results, which is a lot. Any ideas on optimization?
