SQL Server與MySQL和PHP與ColdFusion

Question

這個查詢在ColdFusion中工作正常，但我無法讓它在PHP中工作。 PHP不喜歡我的連接。這兩個查詢有什麼不同？

<cfquery name="getArt" datasource="mssqlcf_PDartist1"> 
select * from artwork a 
join Categories b on (b.CID = a.CID) 
join SubCategories c on (c.CID = b.CID and c.SCID = a.SCID) 
where AID = #AID# 
order by DisplayOrder 
</cfquery> 


<?php 
$dbname = 'pdartist2'; 
$table = 'artwork'; 
$result = mysql_query("SELECT * from artwork") or die(mysql_error()); 
a join Categories b on (b.CID = a.CID) 
join SubCategories c on (c.CID = b.CID and c.SCID = a.SCID) 
where AID = $AID 
order by DisplayOrder 
mysql_free_result($result); 
?> 

Answer 1

您結束了PHP字符串太早。引號必須圍繞整個SQL查詢：

$result = mysql_query("SELECT * 
    FROM artwork a 
    JOIN Categories b ON b.CID = a.CID 
    JOIN SubCategories c ON c.CID = b.CID AND c.SCID = a.SCID 
    WHERE AID = $AID 
    ORDER BY DisplayOrder") or die(mysql_error());
