内部从多个表加入sqlite

Question

按照代码给我一个模糊的列DRIVER.driv_id错误,任何帮助？

SELECT DRIVER.driv_id, DRIVER.firstName, DRIVER.surName, DRIVER.nationality,   TEAMSTANDING.teamName, RESULTS.points
FROM TEAMSTANDING INNER JOIN DRIVER ON TEAMSTANDING.driv_id=DRIVER.driv_id,
RESULTS INNER JOIN DRIVER ON RESULTS.driv_id=DRIVER.drv_id
WHERE TEAMSTANDING.comp_id=2
GROUP BY DRIVER.driv_id;

Answer 1

您必须尝试多次添加驱动程序表以便创建它

SELECT 
    DRIVER.driv_id, DRIVER.firstName, DRIVER.surName, DRIVER.nationality,   TEAMSTANDING.teamName, RESULTS.points   
FROM 
    TEAMSTANDING
    INNER JOIN 
        DRIVER
ON 
        TEAMSTANDING.driv_id=DRIVER.driv_id
    INNER JOIN 
        RESULTS 
    ON 
        RESULTS.driv_id=DRIVER.drv_id
WHERE 
    TEAMSTANDING.comp_id=2
GROUP BY 
    DRIVER.driv_id;
