回答: 要将三个表连接起来,可以使用INNER JOIN或LEFT JOIN语句。根据提供的引用内容,可以使用以下SQL语句将表1、表2和表3连接起来:FROM ((表1 INNER JOIN 表2 ON 表1.字段号=表2.字段号) INNER JOIN 表3 ON 表1.字段号=表3.字段号)。\[1\]另外,如果还需要将表4连接到这个连接的结果中,可以使用以下SQL语句:FROM (((表1 INNER JOIN 表2 ON 表1.字段号=表2.字段号) INNER JOIN 表3 ON 表1.字段号=表3.字段号) INNER JOIN 表4 ON Member.字段号=表4.字段号)。\[2\]如果你想要查询特定的字段,可以使用SELECT语句,例如:SELECT s.Name, C.Cname FROM student_score AS sc LEFT JOIN student AS s ON s.Sno=sc.Sno LEFT JOIN score AS c ON c.Cno=sc.Cno。\[3\]
