mysql表的底层存储是以b+树的形式存储的吗-CFANZ编程社区

一、正式环境查询

SELECT * from tb_village_city as a where a.create_date in （select min(b.编号) from 表A as b where a.编号= b.编号）

1、查询时间最晚的sql

select t.id from tb_village_city as t ,

(select MAX(create_date) as "createDate" from tb_village_city GROUP BY adm_id) as tmp

where t.create_date = tmp. "createDate" and t.adm_id in (

'84c46033-b816-4155-9cd2-fba4e2378e4d',

) and "length"(t."year" )=0 and "length"(t."turns" )=0

2、2019年6月14日镇级数据处理如下

（1）查询单位重复的数据

SELECT "count"(1),adm_id FROM "public"."tb_village_town" group by adm_id having "count"(1)>1;

village-taian

（2）查询是重复数据的且添加数据最晚且年份和轮次是空的数据

select t.id from tb_village_town as t,

(select "max"(create_date) as "createDate" from tb_village_town group by adm_id) as tmp

where t.create_date=tmp."createDate" and t.adm_id in('214bd025-16a3-47da-b02e-ada383e3b817',
