Erratic MySQL results using php

Question

My PHP and MySQL query returns wrong information.

for the purpose of this Query - $PortalAdvertiserOne and $PortalAdvertiserTwo is INT

$sql = "
SELECT * 
  FROM 
     ( SELECT * 
         FROM 100_advertisers_campaigns 
        WHERE vendor_owner IN($PortalAdvertiserOne,$PortalAdvertiserTwo)
          AND ad_section_news = 'Y' 
          AND ad_position = 2 
        ORDER 
           BY RAND() 
        LIMIT 1
     ) x 
 ORDER 
    BY ad_id";

The Query returns everything perfect except where "ad_position" is supposed to return only records with 2, this query returns records from my table with 1, 2, 3 and 4. It does not seem to filter that part of the query.

What am i missing ?

Answer 1

尝试用（）将或四舍五入

$sql = "SELECT * FROM (SELECT * FROM 100_advertisers_campaigns WHERE (vendor_owner = $PortalAdvertiserOne or vendor_owner = $PortalAdvertiserTwo and ad_section_news = 'Y') and ad_position = '2' ORDER BY RAND() LIMIT 1) x ORDER BY ad_id";
