使用INNER JOIN重新创建查询？

Question

如何使用内加入我改变这个查询：

db_query("select max(field_date_and_time_value2) as last_time 
    from field_data_field_date_and_time 
    where (field_date_and_time_value2 > '".$today."') 
    AND (".$node->uid." = (select uid from node where nid = " . $node->nid ."))"); 

Answer 1

from field_data_field_date_and_time fdt 
JOIN node on fdt.<field> = node.uid 

没有看到您的模式，这是很难说的FK是在这里。
