什麼是在MySQL

Question

我要如何使這個sqsl查詢工作連接表的正確方法：

SELECT student.LASTNAME, 
     student.FIRSTNAME, 
     student.IDNO, 
     student.YEAR, 
     parents.P_ADDRESS 
FROM student 
WHERE P_ADDRESS="Ambagat, Santol, LU" 
RIGHT JOIN parents ON student.IDNO = parents.IDNO 

我只想補充WHERE語句的聯接。因爲w3schools中的常用示例不包含where語句。請幫忙。

Answer 1

像這樣

SELECT student.LASTNAME, 
     student.FIRSTNAME, 
     student.IDNO, 
     student.YEAR, 
     parents.P_ADDRESS 
FROM student RIGHT JOIN parents ON student.IDNO=parents.IDNO 
            AND P_ADDRESS="Ambagat, Santol, LU"
