python的pymysql如何插入date类型的字段

Question

用pymysql插入mysql数据库值，关于date字段，需要将str转换成date，变换了好几种写法，也查了很久，不是报语法错误，就是插入的日期不对
请教正确的写法
code=1
date='2016-03-01'
insertresult = cur.execute("insert into data values(%d,str_to_date(%s,'%%Y-%%m
-%%d'))" % (code,date))

Answer 1

Your sql is equivalent to:

insert into data values(1,str_to_date(2016-03-01,'%Y-%m-%d'))

What is needed is '2016-03-01' instead of 2016-03-01

Change

to cur.execute("insert into data values('%d',str_to_date(%s,'%%Y-%%m-%%d'))" % (code,date))
