1、postgresql 数据库update 去重sql
先按重复记录fk分组找最小的记录，然后更新id 不在子查询中的数据
update td_f_stop_history set del_flag='1' where "id" not in
(select "min"("id") from td_f_stop_history where allowed_recover='1' and del_flag='0'
group by fk HAVING "count"(fk)>1)
and allowed_recover='1' and del_flag='0';
2、从一个表查询数据添加到另外一个表中
insert into tf_admin_org2
(org_name,adm_id,org_parent_id,org_code,sort,level,adm_name,del_flag,org_id,unit_id,unit_name,unit_org_case,unit_org_id,is_creat_org,type,change_flag,adm_parent_id,adm_code)
select
d01001,id,parent_id,org_code,sort,level,name,del_flag,org_id,bid,b01001,b99011,d01014,b90007,b90006,change_flag,adm_parent_id,adm_code from tf_admin_org
3、从一张表更新同步到另外一张表
postgresql数据库，软弱涣散基层党组织将一个表中的数据同步到另外一个表
UPDATE tb_village_city_work_progress set org_code=b.org_code
from tf_admin_org b
where tb_village_city_work_progress.adm_id=b.adm_id and tb_village_city_work_progress.adm_id='e6a0755f-7053-45ab-be62-3c0cf6dc6012'
4、查询有多个书记的村庄
SELECT
*
FROM
tb_village_detail
WHERE
ID IN (
SELECT
fk
FROM
"public"."tb_village_lw_member"
WHERE
del_flag = '0'
AND (
duty LIKE '%党支部书记%'
OR duty LIKE '%党总支书记%'
)
AND duty NOT LIKE '%社区%'
GROUP BY
fk
HAVING
COUNT (1) > 1
);
5、统计每个城市软弱涣散村转化完成和未完成的数量
select
城市
sum(CASE WHEN org.weak_lax_status ='0' THEN 1 ELSE 0 END) as 未完成,
sum(CASE WHEN org.weak_lax_status ='1' THEN 1 ELSE 0 END) as 完成
from
info
group by
城市
order by 2
