Question

我收到错误代码：1054。运行以下MySQL查询时，'on clause'错误列中的未知列'vehicle_details.batch_id'。

有人可以帮忙吗？

谢谢，

约翰

仅使用显式连接语法

SELECT 
    supplier,
    vehicle_details.status,
    vehicle_details.batch_id,
    veh_id,
    fund_type,
    suppliers.supplier_name,
    reg_no,
    car_make.car_make,
    car_model,
    creation_date,
    stock_plan,
    money_received,
    hpi_registered,
    invoice_checked,
    details_checked,
    confirmation_received,
    log_mot_check
FROM
    vehicle_details
INNER JOIN suppliers ON vehicle_details.supplier = suppliers.supplier_id
INNER JOIN car_make ON vehicle_details.car_make = car_make.car_id
LEFT JOIN batch ON vehicle_details.batch_id = batch.batch_id
WHERE   vehicle_details.status like 's'
        AND (vehicle_details.batch_id is null or vehicle_details.batch_id like '%')
        AND veh_id like '%'
        AND fund_type like '%'
        AND supplier like '%'
        AND reg_no like '%'
        AND car_id like '%'
        AND car_model like '%'
        AND creation_date like '%'
        AND stock_plan like '%'
        AND money_received like '%'
ORDER BY vehicle_details.batch_id DESC

你在这里隐含

FROM
vehicle_details,
suppliers,
car_make

并有明确的

LEFT JOIN batch ON vehicle_details.batch_id = batch.batch_id

错误代码：1054。未知栏＆＃39; vehicle_details.batch_id＆＃39;在＆＃39; on条款＆＃39;
