Python MySql 插入不起作用

问题描述

我正在使用 python MySQL API 从 python 程序连接到 Mysql 数据库.我从几天就面临一个问题.我无法将记录插入数据库，不知道是什么原因.这是我连接并将记录插入数据库的方式.

I am using python MySQL API to connect to Mysql database from python program. I am facing a problem from few days. I am unable to insert records into the database and dont know whats the reason. Here is the way i connect and insert records into the database.

db = MySQLdb.connect("localhost","root","padmaramulu","pdfsearch" )
cursor = db.cursor()
#cursor.execute("""CREATE TABLE IF NOT EXISTS documents (docid INT NOT NULL ,PRIMARY KEY(docid),docname CHAR(30)) engine=innodb""")
temp = "hello";number = 2;
cursor.execute( 'insert into documents(docid,docname) values("%d","%s")' % (number,temp) )
db.close()

为什么会这样?

推荐答案

在关闭连接之前，你应该添加db.commit().

Before closing the connection, you should add db.commit().
