Oracle數(shù)據(jù)庫也是眾多數(shù)據(jù)庫相對(duì)比較常見的數(shù)據(jù)庫。很多個(gè)人或者企業(yè)都在使用Oracle數(shù)據(jù)庫進(jìn)行處理一些數(shù)據(jù)。就好比Oracle數(shù)據(jù)庫如何識(shí)別個(gè)人信息的等的問題。本文主要介紹Oracle根據(jù)身份證號(hào)獲取人員城市，性別和年齡的信息。同時(shí)用示例代碼向您詳細(xì)展示，該示例代碼對(duì)每個(gè)人的學(xué)習(xí)或工作都有一定的參考價(jià)值，需要的朋友可以參考它。

　　1、通過身份證號(hào)查詢所在省市

　　2、通過身份證號(hào)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(hào)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(hào)統(tǒng)計(jì)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(hào)統(tǒng)計(jì)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')
