mySQL加入where条件

Question

我的数据库中有两个表，它与其他表有一对多连接，如下所示

在kvves_units表中，我会得到＆＃39; name＆＃39;来自GET方法

现在我希望根据kvves_units

的名称获得kvves_members和kvves_units的所有价值

我正在使用类似的代码

$kvvesDetails = $conn->prepare( "SELECT u.id, u.name, u.phone, u.email, u.address, m.name,    m.designantion, m.phone, m.email, m.imageFROM kvves_units AS u JOIN kvves_members AS m ON m.unit_id = u.id WHERE `name` = $committee");

Answer 1

这是标准联接：

$kvvesDetails = $conn->prepare( "SELECT u.id, u.name, u.phone, u.email, u.address, m.name, m.designantion, m.phone, m.email, m.image FROM kvves_units AS u JOIN kvves_members AS m ON m.unit_id = u.id WHERE name = '$committee'"

Answer 2

  

使用此SQL

select kvves_units.*,kvves_members.* from kvves_units a join kvves_members b where a.name = b.name and a.name = '".$_GET['name']."'

Answer 3

尝试：

$name = $_GET['name'];
$sql = "Select *from kvves_units as u INNER JOIN kvves_members as m where u.id = m.unit_id and u.name = '".$name."'";

您将获得解决方案。
