use
dbb.commit()
after
curb.execute ("UPDATE RadioGroups SET CurrentState=1 WHERE RadioID=11")
to commit all the changes that you 'loaded' into the mysql server
Pergunta
I have a python script which needs to update a mysql database, I have so far:
dbb = MySQLdb.connect(host="localhost",
user="user",
passwd="pass",
db="database")
try:
curb = dbb.cursor()
curb.execute ("UPDATE RadioGroups SET CurrentState=1 WHERE RadioID=11")
print "Row(s) were updated :" + str(curb.rowcount)
curb.close()
except MySQLdb.Error, e:
print "query failed<br/>"
print e
The script prints Row(s) were updated :
with the correct number of rows which have a RadioID
of 11. If I change the RadioID
to another number not present in the table it will say Row(s) were updated :0
. However the database doesn't actually update. The CurrentState
field just stays the same. If I copy and past the SQL statement in to PHPMyAdmin it works fine.

As the @Lazykiddy pointed out, you have to commit your changes after you load them into the mysql.
You could also use this approach to enable the auto commit setting, just after the MySQL connection initialization:
dbb.autocommit(True)
Then, it will automatically commit the changes you made during your code execution.
the two answers are correct. However, you can also do this:
dbb = MySQLdb.connect(host="localhost",
user="user",
passwd="pass",
db="database",
autocommit=True)
add autocommit=True
