1、通过身份证号查询所在省市

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 '内蒙古自治区'

when '21' then '辽宁省'

when '22' then '吉林省'

when '23' then '黑龙江省'

when '31' then '上海市'

when '32' then '江苏省'

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 '山东省'

when '41' then '河南省'

when '42' then '湖北省'

when '43' then '湖南省'

when '44' then '广东省'

when '45' then '广西壮族自治区'

when '46' then '海南省'

when '50' then '重庆市'

when '51' then '四川省'

when '52' then '贵州省'

when '53' then '云南省'

when '54' then '西藏自治区'

when '61' then '陕西省'

when '62' then '甘肃省'

when '63' then '青海省'

when '64' then '宁夏回族自治区'

when '65' then '新疆维吾尔自治区'

when '71' then '台湾省'

when '81' then '香港特别行政区'

when '82' then '澳门特别行政区'

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 '内蒙古自治区'

when '21' then '辽宁省'

when '22' then '吉林省'

when '23' then '黑龙江省'

when '31' then '上海市'

when '32' then '江苏省'

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 '山东省'

when '41' then '河南省'

when '42' then '湖北省'

when '43' then '湖南省'

when '44' then '广东省'

when '45' then '广西壮族自治区'

when '46' then '海南省'

when '50' then '重庆市'

when '51' then '四川省'

when '52' then '贵州省'

when '53' then '云南省'

when '54' then '西藏自治区'

when '61' then '陕西省'

when '62' then '甘肃省'

when '63' then '青海省'

when '64' then '宁夏回族自治区'

when '65' then '新疆维吾尔自治区'

when '71' then '台湾省'

when '81' then '香港特别行政区'

when '82' then '澳门特别行政区'

else '未知'end order by province desc

2、通过身份证号得到性别(第17位为奇数为男，偶数为女)

select

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

from uip_ca_userinfo t

3、通过身份证号得到年龄

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

4、通过身份证号统计所在年龄段的人数

select count(t.id),

case

when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 1 and 20 then

'1-20岁'

when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 21 and 30 then

'21-30岁'

when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 31 and 40 then

'31-40岁'

when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 41 and 50 then

'41-50岁'

else

'50岁以上'

end as 年龄段

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岁'

when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 21 and 30 then

'21-30岁'

when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 31 and 40 then

'31-40岁'

when to_char(sysdate, 'yyyy') - substr(t.useridcardnum, 7, 4) between 41 and 50 then

'41-50岁'

else

'50岁以上'

end

order by 年龄段 asc

5、通过身份证号统计男女数量

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')
