如何检查为什么我的INSERT查询不起作用？

Question

conn = MySQLdb.connect(host=IP,user='john',passwd='ab2nng',db='mydb')
cursor = conn.cursor()

#this works.
cursor.execute("select * from crawl_log")
res = cursor.fetchall()
print res

#this doesn't work.
cursor.execute("insert into crawl_log(k, v) values(%s, %s)", ('test','test'))

How do I know why it didn't work? No errors print, nothing.

Answer 1

The typical cause of an issue like this is a misspelling of the row/table/database name

please double check, this is always the main issue with me messing up

ANOTHER thing is that the row/table/db name might be TOO SHORT, to fix this add '' around the name for example, key would be 'key'

hopefully this will fix your issue

Answer 2

By default it will start a transaction which will need to be committed after any statement that affects change to the data. Have you tried conn.commit() after your insert?
