Python mySQL 更新，工作但不更新表

Python mySQL Update, Working but not updating table(Python mySQL 更新，工作但不更新表)

问题描述

我有一个需要更新 mysql 数据库的 python 脚本，目前为止:

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  

脚本打印 Row(s) were updated : 具有正确的行数，其中 RadioID 为 11.如果我更改 RadioID 到表中不存在的另一个数字，它会说 Row(s) were updated :0.但是数据库实际上并没有更新.CurrentState 字段保持不变.如果我将 SQL 语句复制并粘贴到 PHPMyAdmin 中，它可以正常工作.

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.

推荐答案

使用

dbb.commit()

之后

curb.execute ("UPDATE RadioGroups SET CurrentState=1 WHERE RadioID=11")

提交您加载"到 mysql 服务器的所有更改

to commit all the changes that you 'loaded' into the mysql server
