Mysql 根據身份證號碼操作

前言

主要是針對一些針對身份證號碼進行數據分析的場景，進行一些SQL的備忘記錄。

年齡

(YEAR(CURDATE()) - SUBSTRING(身份證字段項,7,4)) AS 年齡,

性別

-- 1 男 2 女 
IF (MOD(SUBSTRING(身份證字段項,17,1),2),1,2) AS 性別
-- 漢字
IF (MOD(SUBSTRING(身份證字段項,17,1),2),'男','女') AS 性別

出生日期

substring(身份證字段項,7,8) as 出生日期

歸屬地

CASE LEFT(身份證字段項,2) WHEN 11 THEN '北京' WHEN 12 THEN '天津' 
WHEN 13 THEN '河北' WHEN 14 THEN '山西' WHEN 15 THEN '內蒙古' 
WHEN 21 THEN '遼寧'WHEN 22 THEN '吉林' WHEN 23 THEN '黑龍江' 
WHEN 31 THEN '上海' WHEN 32 THEN '江蘇' WHEN 33 THEN '浙江' 
WHEN 34 THEN '安徽' WHEN 35 THEN '福建' WHEN 36 THEN '江西' 
WHEN 37 THEN '山東' WHEN 41 THEN '河南' WHEN 42 THEN '湖北' 
WHEN 43 THEN '湖南' WHEN 44 THEN '廣東' WHEN 45 THEN '廣西' 
WHEN 46 THEN '海南' WHEN 50 THEN '重慶' WHEN 51 THEN '四川' 
WHEN 52 THEN '貴州' WHEN 53 THEN '雲南' WHEN 54 THEN '西藏' 
WHEN 61 THEN '陝西' WHEN 62 THEN '甘肅' WHEN 63 THEN '青海' 
WHEN 64 THEN '寧夏' WHEN 65 THEN '新疆' END AS 所屬省份

脫敏

INSERT(身份證字段項,7,6,'****') as 身份證號碼脫敏
