pymysql.err.InternalError: (1054, "Unknown column ‘None‘ in ‘field list‘")
import pymysql # 创建连接 conn = pymysql.connect(host=‘192.168.72.135‘, port=3306, user=‘root‘, passwd=‘123456‘, db=‘test‘) # 创建游标 cursor = conn.cursor() # 执行SQL，并返回收影响行数 effect_row = cursor.execute("insert into `222` set c={}".format(None)) # 提交，不然无法保存新建或者修改的数据 conn.commit() # 关闭游标 cursor.close() # 关闭连接 conn.close()
解决办法：
把None 换成“Null”
effect_row = cursor.execute("insert into `222` set c={}".format("Null"))
