要在MySQL数据库中插入日期,您的表中必须有一个类型为date或datetime的列。一旦有了它,就需要将日期转换为字符串格式,然后再将其插入数据库。为此,您可以使用datetime模块的strftime格式化功能。
from datetime import datetime now = datetime.now() id = 1 formatted_date = now.strftime('%Y-%m-%d %H:%M:%S') # Assuming you have a cursor named cursor you want to execute this query on: cursor.execute('insert into table(id, date_created) values(%s, %s)', (id, formatted_date))
运行此命令将尝试在表中插入元组(id,日期)。
当您使用选择查询从数据库中获取日期时,您需要使用诸如strptime之类的函数将其解析回datetime对象。
from datetime import datetime # Assuming you have a cursor named cursor you want to execute this query on: cursor.execute('select id, date_created from table where id=1') # if you inserted the row above, you can get it back like this id, date_str = cursor.fetchone() # date is returned as a string in format we sent it as. So parse it using strptime created_date = datetime.strptime(date_created, '%Y-%m-%d %H:%M:%S')
这将获取创建的日期并将其解析为datetime对象。
