SELECT multiple rows where where matching four condition or more

-4

我遇到了我的php代码选择问题，我想从满足四个条件的表中选择一行。SELECT multiple rows where where matching four condition or more

$course = $_GET['Course']; 
$year_enrolled = $_GET['Year_Enrolled']; 
$month = $_GET['Month']; 
$year = $_GET['Year']; 

$sql=" SELECT * FROM dtr WHERE Course like '%$course%' OR Year_enrolled like '%$year_enrolled%' AND Month like '%$month%' OR Year like '%$year%'";

这是可能的。但是我们如何在没有看到您正在使用的SQL的情况下回答？ – samiles

您可能想编辑您的问题以包含您的代码。 – ollie

$ course = $ _GET ['Course']; $ year_enrolled = $ _GET ['Year_Enrolled']; \t $ month = $ _GET ['Month']; \t $ year = $ _GET ['Year']; \t $ sql =“SELECT * FROM dtr WHERE课程喜欢'％$ course％'或Year_enrolled喜欢'％$ year_enrolled％'以及月份喜欢'％$ month％'或者像'％$ year％'这样的年份”; –

这段代码给了我这种问题的准确结果。

$sql= " SELECT * FROM dtr WHERE Course like '%$course%' AND Year_enrolled like '%$year_enrolled%' AND (Month like '%$month%' AND Year like '%$year%')";
