如何使用单个查询如

Question

如何在单个查询中进行以下查询。

$result = db_query("SELECT replace(source, 'node/', '') as source FROM {url_alias} where source like 'node/%' limit 11"); 
foreach ($result as $record) { 
$result2 = db_query("SELECT fci.* FROM {node} AS fci LEFT JOIN {node_access} AS fdfp ON fci.nid = fdfp.nid where fci.nid = :item_id AND fdfp.nid IS NULL", array(':item_id' => $record->source)); 
    foreach ($result2 as $record2) { 
    echo '<pre>'; 
    print_r($record2); 
    } 
} 

Answer 1

SELECT fci.* 
    FROM {node} AS fci 
    INNER JOIN {url_alias} ON fci.nid = REPLACE(source, 'node/', '') 
    LEFT JOIN {node_access} AS fdfp ON fci.nid = fdfp.nid 
    WHERE source LIKE 'node/%' AND fdfp.nid IS NULL 
    LIMIT 11 

Answer 2

$result2 = db_query("SELECT fci.* FROM {node} AS fci LEFT JOIN {node_access} AS fdfp ON fci.nid = fdfp.nid where fci.nid IN(SELECT replace(source, 'node/', '') as source FROM {url_alias} where source like 'node/%') AND fdfp.nid IS NULL"); 
foreach ($result2 as $record2) { 
    echo '<pre>'; 
    print_r($record2); 
}
