Question

我目前正在使用高级搜索从数据库中搜索记录。我也为此创建了脚本，我使用OR运算符和BETWEEN查询，但我对如何使用从最小到最大的请求率感到困惑。如何将AND OR运算符与BETWEEN等MySQL搜索查询一起使用？

if ($result = mysqli_query($con, "SELECT * FROM meta WHERE title='$title' OR 
        discription='$discription' OR region='$region' OR city='$city' OR 
        sector='$sector' OR minimum='$minimum' OR mini='$mini' OR minni='$minni'"))

Answer 1

OR（'$ var'＆gt; minimum AND'$ var'＆lt; maximum）

Answer 2

OR ('$var' BETWEEN minimum AND maximum)

Answer 3

您可以在

之间使用

从meta中选择*，其中title =＆＃39; $ title＆＃39;和（在＆$ 39; $ start_date＆＃39;和$ 39; $ end_date＆＃39;）之间的日期。

Answer 4

SELECT * FROM meta WHERE  
        (
           title='$title' OR 
           discription='$discription' OR region='$region' OR city='$city' OR 
           sector='$sector' OR minimum='$minimum' OR mini='$mini' OR minni='$minni' 
        ) -- Atleast one of the above or conditions must be true
        AND  (date between '$start_date' and '$end_date');

OR

SELECT * FROM meta WHERE  
        (
           title='$title' OR 
           discription='$discription' OR region='$region' OR city='$city' OR 
           sector='$sector' OR minimum='$minimum' OR mini='$mini' OR minni='$minni' 
        ) -- Atleast one of the above or conditions must be true
        AND  (date > '$start_date' and date < '$end_date');

使用AND和OR运算符从数据库中搜索记录
