如何编写选择查询集合匹配

Question

请帮我解决问题的想法。 我不能去想子查询

SELECT名称从客户那里assest_id IN（？子查询？）

Answer 1

对于第一问题

select name from client where asset_id in(
select asset_id from client_asset where 
asset_desc='2' 
intersect 
select asset_id from client_asset where 
asset_id not in (select asset_id from client_asset where 
       asset_name not in ('apartment','byke'))); 

对于第一个问题首先我已经用2room提取了asset_id，用intersected提取了只有byke and apartmenta的asset_id他们的资产。这是作为子查询中被围堵的语句来获取asset_id

对于第二个问题

select name from client where asset_id in 
(select asset_id from client_asset where 
asset_desc>='2' and asset_name='apartment' 
intersect 
select asset_id from client_asset where 
asset_name='car'); 

这个查询是自explainatory和作品以类似理由
