[英]What's the proper way of joining tables in mysql
How do I get to make this sqsl query work: 我如何使这个sqsl查询工作:
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
I just want to add where statement on the joins. 我只想在联接上添加where语句。 Because the usual example in w3schools doesn't include a where statement.
因为在w3schools中,通常的示例不包含where语句。 Please help.
请帮忙。
Like this 像这样
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"
