Python 如何在djnago的insert查询中动态使用列名

在上面的查询中，我希望动态地传递列名，并且%s在值中也不预定义它需要写入多少次

那么，如何根据来自2d数组中html表的数据编写sql查询？？？

我们需要在使用查询之前构建查询。如下

cursor.execute("insert into demoapp_site ('name','firstname','lastname') values (%s,%s,%s)",site_data)

field_string = ""
value_string = ""

# This will string in this format "'field1','field2'"
# Assuming array is in format [["field1", "value1"],..]
# Update the for loop statement based on your input, other lines remain same 
for field, value in my_field_array:
    temp_field_string = "'%s'" % field
    field_string = field_string + temp_field_string + ","
    temp_value_string = "'%s'" % value
    value_string = value_string + temp_value_string + ","

# Removing trailing comma's before passing the values
cmd = "insert into demoapp_site (%s) values (%s)" % (field_string[:-1], value_string[:-1])
cursor.execute(cmd)
