這篇文章主要介紹了Oracle按身份證號得到省市、性別、年齡,本文通過示例代碼給大家介紹的非常詳細，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值，需要的朋友可以參考下

1、通過身份證號查詢所在省市

SELECT
count(*) as total,
 case substr(t.CERTNO,0,2)
  when '11' then '北京市'
  when '12' then '天津市'
  when '13' then '河北省'
  when '14' then '山西省'
  when '15' then '內(nèi)蒙古自治區(qū)'
  when '21' then '遼寧省'
  when '22' then '吉林省'
  when '23' then '黑龍江省'
  when '31' then '上海市'
  when '32' then '江蘇省'
  when '33' then '浙江省'
  when '34' then '安徽省'
  when '35' then '福建省'
  when '36' then '江西省'
  when '37' then '山東省'
  when '41' then '河南省'
  when '42' then '湖北省'
  when '43' then '湖南省'
  when '44' then '廣東省'
  when '45' then '廣西壯族自治區(qū)'
  when '46' then '海南省'
  when '50' then '重慶市'
  when '51' then '四川省'
  when '52' then '貴州省'
  when '53' then '云南省'
  when '54' then '西藏自治區(qū)'
  when '61' then '陜西省'
  when '62' then '甘肅省'
  when '63' then '青海省'
  when '64' then '寧夏回族自治區(qū)'
  when '65' then '新疆維吾爾自治區(qū)'
  when '71' then '臺灣省'
  when '81' then '香港特別行政區(qū)'
  when '82' then '澳門特別行政區(qū)'
  else '未知'
  end AS province
 FROM uip_bjt_userinfo t 
 group by case substr(t.CERTNO,0,2)
    when '11' then '北京市'
    when '12' then '天津市'
    when '13' then '河北省'
    when '14' then '山西省'
    when '15' then '內(nèi)蒙古自治區(qū)'
    when '21' then '遼寧省'
    when '22' then '吉林省'
    when '23' then '黑龍江省'
    when '31' then '上海市'
    when '32' then '江蘇省'
    when '33' then '浙江省'
    when '34' then '安徽省'
    when '35' then '福建省'
    when '36' then '江西省'
    when '37' then '山東省'
    when '41' then '河南省'
    when '42' then '湖北省'
    when '43' then '湖南省'
    when '44' then '廣東省'
    when '45' then '廣西壯族自治區(qū)'
    when '46' then '海南省'
    when '50' then '重慶市'
    when '51' then '四川省'
    when '52' then '貴州省'
    when '53' then '云南省'
    when '54' then '西藏自治區(qū)'
    when '61' then '陜西省'
    when '62' then '甘肅省'
    when '63' then '青海省'
    when '64' then '寧夏回族自治區(qū)'
    when '65' then '新疆維吾爾自治區(qū)'
    when '71' then '臺灣省'
    when '81' then '香港特別行政區(qū)'
    when '82' then '澳門特別行政區(qū)'
    else '未知'end order by province desc

2、通過身份證號得到性別（第17位為奇數(shù)為男，偶數(shù)為女）

select 
  decode(mod(to_number(substr(t.useridcardnum, 17, 1)), 2),0,'女','男') as sex
 from uip_ca_userinfo t

3、通過身份證號得到年齡

select to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) as age from uip_ca_userinfo t

4、通過身份證號統(tǒng)計所在年齡段的人數(shù)

select count(t.id),
  case
   when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 1 and 20 then
   '1-20歲'
   when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 21 and 30 then
   '21-30歲'
   when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 31 and 40 then
   '31-40歲'
   when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 41 and 50 then
   '41-50歲'
   else
   '50歲以上'
  end as 年齡段
 from uip_ca_userinfo t
 group by case
   when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 1 and 20 then
    '1-20歲'
   when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 21 and 30 then
    '21-30歲'
   when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 31 and 40 then
    '31-40歲'
   when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 41 and 50 then
    '41-50歲'
   else
    '50歲以上'
   end
 order by 年齡段 asc

5、通過身份證號統(tǒng)計男女?dāng)?shù)量

select count(t.id),
  decode(mod(to_number(substr(t.useridcardnum, 17, 1)), 2),0,'女','男') as sex
 from uip_ca_userinfo t
 where to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 1 and 26
 group by decode(mod(to_number(substr(t.useridcardnum, 17, 1)), 2),0,'女','男')
