我知道Zend提供了一个having()方法,但我想要的是一个类似的查询:
SELECT a.*, `as`.* FROM `fruit_db`.`apples` AS `a`
INNER JOIN `fruit_db`.`apple_seeds` AS `as` ON a.id = as.apple_id
WHERE (a.id = 1) AND as.seed_name HAVING 'johnny'
不是“HAVING(as.seed_name ='johnny')”
回溯一下,我们有表格:
fruit_db.apples
| id | name |
--------------
| 1 | red |
| 2 | green|
fruit_db.apple_seeds
| apple_id | seed_name |
------------------------
| 1 | johnny |
| 1 | judy |
| 2 | granny |
我想要的结果如下:
| id | name | apple_id | seed_name |
-------------------------------------
| 1 | red | 1 | johnny |
| 1 | red | 1 | judy |
上面提供的查询给出了这个结果,但是使用Zend_Db_Select将括号括在having和where语句的每个部分周围,这些部分使我的查询无效。所以
$zend_db_table->select()
->setIntegrityCheck(false)
->from(array("a" => "apples"), array("*"))
->join(array("as"=>"apple_seeds"),
"a.id = as.apple_id",
array("*"))
->where('a.id = 1')
->where('as.seed_name HAVING "johnny"');
产生
SELECT a.*, `as`.* FROM `fruit_db`.`apples` AS `a`
INNER JOIN `fruit_db`.`apple_seeds` AS `as` ON a.id = as.apple_id
WHERE (a.id = 1) AND (as.seed_name HAVING 'johnny')
哪个是无效的SQL。简而言之:
SELECT a.*, `as`.* FROM `fruit_db`.`apples` AS `a`
INNER JOIN `fruit_db`.`apple_seeds` AS `as` ON a.id = as.apple_id
WHERE (a.id = 1) AND as.seed_name HAVING 'johnny'
有效,但是:
SELECT a.*, `as`.* FROM `fruit_db`.`apples` AS `a`
INNER JOIN `fruit_db`.`apple_seeds` AS `as` ON a.id = as.apple_id
WHERE (a.id = 1) AND (as.seed_name HAVING 'johnny')
Zend生成的是无效的SQL。我不希望只有一行看到了'johnny',我想要所有行,其中apple id = 1 AND seed_name'johnny'就在这些结果的某个地方。我可以通过Zend_Db_Select得到我需要的东西,还是需要去原始查询()路线?
编辑:我已将问题修改为更接近我想要的内容并试图澄清一下。
答案 0 :(得分:1)
变化
- > where('as.apple_id HAVING 1');
到
- >有('as.apple_id = 1');
