本文主要向大家介紹了MySQL數據庫之在mysql中給查詢的結果添加序號列 ，通過具體的內容向大家展現，希望對大家學習MySQL數據庫有所幫助。

一：第一種：

select???(@i:=@i+1)???as???i,table_name.*???from???table_name,(select???@i:=0)???as???it

例如：

(1)簡單實例：select??(@i:=@i+1)??i,user_id?from??spcp_user_20170803?,(select???@i:=0)???as???it?ORDER?BY?t.user_id?desc;

(2)復雜實例：

SELECT

(@i:=@i+1)?as?i,hs_cd,hs_owner_persons,hs_owner_certy_num,hs_full_addr,t5.value_name?as?hs_type,t6.value_name?as?hs_owner_type,hs_use_size,hs_build_size,t2.cj_num,t2.db_num,t2.high_age_num,t2.ls_person_num,t7.value_name?as?person_type,t4.org_name

FROM

house_info_20170803?t1,house_person_info_20170803?t2,person_info_20170803?t3,cmp_org?t4,cfg_value?t5,cfg_value?t6,cfg_value?t7,(select?@i:=0)?as?it

WHERE

t1.hs_owner_certy_num?IN?(

SELECT

hs_owner_certy_num

FROM

house_info_20170803

GROUP?BY

hs_owner_certy_num

HAVING

COUNT(*)?>?1

)

and?t1.hs_id=t2.hs_id

and?t2.hs_id=t3.old_hs_id

and?t1.tt_org_id=t4.org_id

and?(t1.hs_type=t5.value_cd?and?t5.item_cd=‘HS_TYPE‘)

and?(t1.hs_owner_type=t6.value_cd?and?t6.item_cd=‘HS_OWNER_TYPE‘)

and?(t3.person_type=t7.value_cd?and?t7.item_cd=‘PERSON_TYPE‘);

二、第二種：

set?@rownum=0;

select?@rownum:=@rownum+1?as?rownum,?t.*?from?table_name?t?order?by?t.id?desc?limit?10

(1)簡單實例

set?@rownum=0;

select?@rownum:=@rownum+1?as?rownum,?t.hs_id?from?house_info_20170803?t?order?by?t.hs_id?desc?limit?10
