Question

Good Morning.

Araçlardaki lastik değişimlerine ve denetimlere dayalı bir rapor yapmam istendi.

Yazının altındaki farklı parçaları iliştiriyorum.

Ama temelde konulmuştur ve başka lastik yerini vb

çekerken bir lastik varlık arasındaki fark esas belirli bir konumda ne kadar uzun öğrenmek yapmanız gereken ne hayır var Genel olarak sql sunucusuna yeni olduğum için bu sorgu ile başlayacağım fikri. sql

benim tablolar

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) 
); 

Ben sonraki adım sql

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; 

Bu sonuç ekli

sonucu tablo olarak bu tablolardan baz ayrıntıları çekin etmektir vardır ile ilişkili kayıt formları bir masale olarak teslim edilir tablo
