查询过滤器将子查询分配给一个字段值

Question

我从最近两天就陷入了这个问题。

请帮忙。

我想分配以下查询。

$qr = "(select subconfigcode.field_subconfigcode_value AS configcode FROM node node LEFT JOIN field_data_field_select_parent_configuratio select_parent_configuratio ON node.nid = select_parent_configuratio.entity_id AND (select_parent_configuratio.entity_type = node AND select_parent_configuratio.deleted = 0) LEFT JOIN node select_parent_configuratio_node ON select_parent_configuratio.field_select_parent_configuratio_nid = select_parent_configuratio_node.nid LEFT JOIN field_data_field_subconfigcode subconfigcode ON select_parent_configuratio_node.nid = subconfigcode.entity_id AND (subconfigcode.entity_type = 'node' AND subconfigcode.deleted = '0') WHERE (((select_parent_configuratio.field_select_parent_configuratio_nid = node_field_data_field_select_parent_configuratio.nid))AND(((node.status = '1') AND (node.type IN ('offering'))))) ORDER BY node.created DESC, configcode ASC LIMIT 1 OFFSET 0)"; 

到

一个视图的字段值。

我已经使用了下面的代码。

function general_views_query_alter(&$view, &$query) { 
     $qr = " (select subconfigcode.field_subconfigcode_value AS configcode FROM node node LEFT JOIN field_data_field_select_parent_configuratio select_parent_configuratio ON node.nid = select_parent_configuratio.entity_id AND (select_parent_configuratio.entity_type = node AND select_parent_configuratio.deleted = 0) LEFT JOIN node select_parent_configuratio_node ON select_parent_configuratio.field_select_parent_configuratio_nid = select_parent_configuratio_node.nid LEFT JOIN field_data_field_subconfigcode subconfigcode ON select_parent_configuratio_node.nid = subconfigcode.entity_id AND (subconfigcode.entity_type = 'node' AND subconfigcode.deleted = '0') WHERE (((select_parent_configuratio.field_select_parent_configuratio_nid = node_field_data_field_select_parent_configuratio.nid))AND(((node.status = '1') AND (node.type IN ('offering'))))) ORDER BY node.created DESC, configcode ASC LIMIT 1 OFFSET 0)"; 

     $query->add_where(1, "node_field_data_field_select_parent_configuratio__field_data_field_subconfigcode.field_subconfigcode_value", $qr); 

    } 

但是，它返回以下哪里查询。

where node_field_data_field_select_parent_configuratio__field_data_field_subconfigcode.field_subconfigcode_value = '(select subconfigcode.field_subconfigcode_value AS configcode FROM node node LEFT JOIN field_data_field_select_parent_configuratio select_parent_configuratio ON node.nid = select_parent_configuratio.entity_id AND (select_parent_configuratio.entity_type = node AND select_parent_configuratio.deleted = 0) LEFT JOIN node select_parent_configuratio_node ON select_parent_configuratio.field_select_parent_configuratio_nid = select_parent_configuratio_node.nid LEFT JOIN field_data_field_subconfigcode subconfigcode ON select_parent_configuratio_node.nid = subconfigcode.entity_id AND (subconfigcode.entity_type = \'node\' AND subconfigcode.deleted = \'0\') WHERE (((select_parent_configuratio.field_select_parent_configuratio_nid = node_field_data_field_select_parent_configuratio.nid))AND(((node.status = \'1\') AND (node.type IN (\'offering\'))))) ORDER BY node.created DESC, configcode ASC LIMIT 1 OFFSET 0) ') 

我想查询，而无需分配给子查询单引号和删除多余的削减添加到每个值。

请帮忙。

答：

直接查询不适用于在add_where条件分配的目的。

为此，我使用了生成的查询对象。

function general_views_query_alter(&$view, &$query) { 
        $subQuery = db_select('node', 'node'); $subQuery->leftJoin('field_data_field_select_parent_configuratio', 'select_parent_configuratio ', 'node.nid = select_parent_configuratio .entity_id'); 
        $subQuery->condition('select_parent_configuratio.entity_type', 'node', '='); 
        $subQuery->condition('select_parent_configuratio.deleted', '0', '='); 
        $subQuery->leftJoin('node', 'select_parent_configuratio_node', 'select_parent_configuratio.field_select_parent_configuratio_nid = select_parent_configuratio_node.nid'); 
        $subQuery->leftJoin('field_data_field_subconfigcode', 'subconfigcode', 'select_parent_configuratio_node.nid = subconfigcode.entity_id');  
        $subQuery->condition('subconfigcode.entity_type', 'node', '='); 
        $subQuery->condition('subconfigcode.deleted', '0', '='); 
        $subQuery->where("select_parent_configuratio.field_select_parent_configuratio_nid = node_field_data_field_select_parent_configuratio.nid"); 
        $subQuery->condition('node.status', "1", '='); 
        $subQuery->condition('node.type', array('offering'), 'IN'); 
        $subQuery->orderBy('configcode'); 
        $subQuery->addField('subconfigcode', 'field_subconfigcode_value', 'configcode'); 
        //$subQuery->range(0, 1); 
        $query->add_where($group,'node_field_data_field_select_parent_configuratio__field_data_field_subconfigcode.field_subconfigcode_value',$subQuery,'in'); 
} 

使用这个，我能够生成它的查询和赋值变量的值。
