使用 Zend 框架进行 UNION 和 NOT IN Mysql 操作

Question

我需要在 Zend 中执行以下 mysql 查询；我不是 Zend 框架的专家，

SELECT  `optionride`.`featureoption_id`,
`optionride`.`featureoptionride_id`,`foption`.`featureoptionblock_id`,

`foption`.`labelname`,`optionride`.`value` FROM 
`engine4_ride_featureoptionrides` AS `optionride` 
LEFT JOIN `engine4_ride_featureoptions` AS `foption` 
ON foption.featureoption_id = optionride.featureoption_id 
WHERE (optionride.ride_id = '1' ) AND (foption.featureoptiontab_id= '2' )

UNION

SELECT `foption`.`featureoption_id`,  null as    
`featureoptionride_id`,`foption`.`featureoptionblock_id`,
`foption`.`labelname`,null as `value` FROM `engine4_ride_featureoptions` AS `foption`
WHERE (foption.featureoptiontab_id= '2' ) AND `foption`.`featureoption_id` NOT IN
(
   SELECT `optionride`.`featureoptionride_id` FROM `engine4_ride_featureoptionrides`   
   AS `optionride` 
   LEFT JOIN `engine4_ride_featureoptions` AS `foption` ON 
   foption.featureoption_id   =      optionride.featureoption_id 
  WHERE (optionride.ride_id = '1' ) AND (foption.featureoptiontab_id= '2' )
 )

任何人都可以帮助我。

您可以将所有查询放在 $db->fetch() 中。

您也可以使用 $db->select()->union(array($sql1, $sql2))，其中 $sql1, $sql2 可以是 $db->select() 或字符串（"select..."）。

对于NOT IN，您可以使用$db->where('someField NOT IN (?)', array());
