SQL查詢來提取基於兩個條件

Question

我在這個結構

cars - id | brand | type | license 
equipments - id | name | description 
distances - id_car | date | distance 
cars_equipments - id_car | id_equipment 

四個表，我必須提取有裝備「滅火器」那個開車昨天所有的車......

我已成功地創建此到目前爲止

SELECT cars.id, cars.brand, cars.type, cars.license, cars_equipments.id_car 
FROM equipments 
INNER JOIN cars_equipments ON equipments.id = cars_equipments.id_equipment 
INNER JOIN cars ON cars.id = cars_equipments.id_car 
INNER JOIN distances ON distances.id_car = cars.id 
WHERE equipments.name LIKE 'fire extinguisher' 

這個只返回有「滅火器」，所以它不能正常工作一輛車，如果我添加

AND distances.date = DATE_SUB(NOW(), INTERVAL 1 DAY) 

將其與最後一天不起作用。

Answer 1

它適合你嗎？

SELECT cars.id, cars.brand, cars.type, cars.license, cars_equipments.id_car 
FROM cars 
    INNER JOIN cars_equipments ON cars.id = cars_equipments.id_car 
    INNER JOIN equipments ON equipments.id = cars_equipments.id_equipment 
    INNER JOIN distances ON distances.id_car = cars.id 
WHERE equipments.name LIKE 'fire extinguisher' 
AND distances.date >= dateadd(day,datediff(day,0,GETDATE()),-1) 
AND distances.date < dateadd(day,datediff(day,0,GETDATE()),0)
