I'm trying to execute a basic INSERT statement on a MySQL table from a Python script using MySQLdb. My table looks like this:
CREATE TABLE `testtable` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`testfield` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
)
Running this query from the MySQL command line works fine:
INSERT INTO `testtable` (`id`, `testfield`) VALUES (NULL, 'testvalue');
But when I try to execute the query from a Python script, no rows get inserted. Here's my code:
conn = MySQLdb.connect(host=db_host, port=db_port, user=db_user, passwd=db_password, db=db_database)
cursor = conn.cursor ()
cursor.execute ("INSERT INTO `testtable` (`id`, `testfield`) VALUES (NULL, 'testvalue')")
print "Number of rows inserted: %d" % cursor.rowcount
cursor.close()
conn.close()
Oddly, this will print "Number of rows inserted: 1." I can also confirm that this query increments the ID field, because when I add another row via the command line, the value of its ID is the same as if the Python script had successfully inserted its rows. However, running a SELECT query returns none of the rows from the script.
Any idea what's going wrong?
