Sql server 基于早期结果获取Sql集中的下一个关联记录结果

早上好

我被要求做一份关于轮胎更换和车辆检查的报告

我把不同的部分贴在柱子的底部

但我基本上要做的是找出一个轮胎在资产上的特定位置有多长时间，以及它被安装的时间与另一个轮胎被替换的时间之间的差异等等

我甚至不知道从哪里开始这个查询，因为我对sql server一般都是新手

我的sql表是

    CREATE TABLE assets_tyre_change_header
( id INT NOT NULL IDENTITY(1,1),
  change_date date not null,
  asset_id varchar(50) not null,
  odometer_hour varchar(50),
  completed tinyint,
  comment text,
  CONSTRAINT assets_tyre_change_pk PRIMARY KEY (id)
);

CREATE TABLE assets_tyre_change_details
( id INT NOT NULL IDENTITY(1,1),
  tyre_change_id INT,
  tyre_id varchar(50) not null,
  wheel_position varchar(50) not null,
  tread_depth int not null,
  minimum_depth int not null
  CONSTRAINT assets_tyre_change_detail_pk PRIMARY KEY (id)
);

create table assets_tyre_inspection_header
( id INT NOT NULL IDENTITY(1,1),
  inspection_date date not null,
  asset_id varchar(50) not null,
  odometer_hour varchar(50),
  completed tinyint,
  comment text,
  CONSTRAINT assets_tyre_inspection_pk PRIMARY KEY (id)
);

CREATE TABLE assets_tyre_inspection_details
( id INT NOT NULL IDENTITY(1,1),
  tyre_inspection_id INT,
  tyre_id varchar(50) not null,
  wheel_position varchar(50) not null,
  tread_depth int not null
  CONSTRAINT assets_tyre_inspection_detail_pk PRIMARY KEY (id)
);

我的下一步是从这些表中提取基本细节作为结果表

sql附加

select * from (
(select 'change' as type,
    tyre_id,
    asset_id,
    wheel_position,
    min(convert(int,odometer_hour))as min_oh,
    max(convert(int,odometer_hour))as max_oh,
    min(tread_depth)as min_depth,
    min(change_date) as transdate 
    from assetsandfuel.dbo.assets_tyre_change_details as c_details
    join assetsandfuel.dbo.assets_tyre_change_header as c_header on c_header.id = c_details.tyre_change_id
    group by asset_id,tyre_id,wheel_position
)
union
(select 'inspect' as type,
tyre_id,
asset_id,
wheel_position,
min(convert(int,odometer_hour))as min_oh,
max(convert(int,odometer_hour))as max_oh,
min(tread_depth)as min_depth,
min(inspection_date) as transdate 
from assetsandfuel.dbo.assets_tyre_inspection_details as i_details
join assetsandfuel.dbo.assets_tyre_inspection_header as i_header on i_header.id = i_details.tyre_inspection_id
group by asset_id,tyre_id,wheel_position
)
)as report_table
order by transdate;

这将导致以下记录作为表格结果交付

非常感谢。我正在尝试编辑它以插入我的检查表。但到目前为止，前景看好。我会让你知道结果的
