[英]how to get this query into Zend_db_select
我有以下查詢:
SELECT *
FROM
(SELECT products.uid, products.title, products.ean, products.description, products.price, products.date_publish, publishers.name, GROUP_CONCAT( CONCAT (authors.first_name, ' ', authors.last_name) SEPARATOR ', ') AS authors
FROM products
INNER JOIN publishers
ON products.uid_publisher = publishers.uid
INNER JOIN products_authors_mm
ON products.uid = products_authors_mm.uid_product
INNER JOIN authors
ON products_authors_mm.uid_author = authors.uid
GROUP BY products.uid) AS t
WHERE title LIKE '%jerzy%' OR name LIKE '%jerzy%' OR authors LIKE '%jerzy%'
當我嘗試將其放入zend_db_select
查詢中時:
$selectProducts = $db->select()
->from('products', array('products.uid AS id',
'products.title',
'products.ean',
'products.description',
'products.price',
'products.date_publish',
'publishers.name',
'GROUP_CONCAT( CONCAT (authors.first_name, \' \', authors.last_name) SEPARATOR \', \') AS authors'))
->join('publishers', 'products.uid_publisher = publishers.uid')
->join('products_authors_mm', 'products.uid = products_authors_mm.uid_product')
->join('authors', 'products_authors_mm.uid_author = authors.uid')
->group('products.uid');
$finalSelect = $db->select()
->from($selectProducts)
->where('t.title LIKE ?', '%' . $query . '%')
->orWhere('t.name LIKE ?', '%' . $query . '%')
->orWhere('t.authors LIKE ?', '%' . $query . '%');
MYSQL給我以下錯誤:
消息:SQLSTATE [42S21]:列已存在:1060重復的列名“名稱”
當我呼應$finalSelect
,得到以下查詢:
SELECT `t`.*
FROM
(SELECT `products`.`uid` AS `id`, `products`.`title`, `products`.`ean`, `products`.`description`, `products`.`price`, `products`.`date_publish`, `publishers`.`name`,
GROUP_CONCAT( CONCAT (authors.first_name, ' ', authors.last_name) SEPARATOR ', ') AS `authors`**, `publishers`.*, `products_authors_mm`.*, `authors`.***
FROM `products`
INNER JOIN `publishers` ON products.uid_publisher = publishers.uid
INNER JOIN `products_authors_mm` ON products.uid = products_authors_mm.uid_product
INNER JOIN `authors` ON products_authors_mm.uid_author = authors.uid
GROUP BY `products`.`uid`) AS `t`
WHERE (t.title LIKE '%Andrzej%') OR (t.name LIKE '%Andrzej%') OR (t.authors LIKE '%Andrzej%')
當我從那里刪除publishers.*, products_authors_mm.*, authors.*
時,它可以正常工作。
所以我的問題是,如何更改此查詢的PHP代碼才能正常工作?
我可以按照以下方式更改您的SQL嗎?
SELECT products.uid,
products.title,
products.ean,
products.description,
products.price,
products.date_publish,
publishers.name,
GROUP_CONCAT( CONCAT (authors.first_name, ' ', authors.last_name) SEPARATOR ', ') AS authors
FROM products
INNER JOIN publishers ON products.uid_publisher = publishers.uid
INNER JOIN products_authors_mm ON products.uid = products_authors_mm.uid_product
INNER JOIN authors ON products_authors_mm.uid_author = authors.uid
GROUP BY products.uid
WHERE title LIKE '%jerzy%' OR name LIKE '%jerzy%' OR authors LIKE '%jerzy%'
如果正確,則可以使用以下zend查詢。
$db->select()
->from(array('a' => 'products'), array('uid', 'title', 'ean', 'description', 'price', 'date_publish'))
->join(array('b' => 'publishers'), 'a.uid_publisher = b.uid', array('name'))
->join(array('c' => 'products_authors_mm'), 'a.uid = c.uid_product', '')
->join(array('d' => 'authors'), 'c.uid_author = d.uid', array('GROUP_CONCAT( CONCAT (authors.first_name, ' ', authors.last_name) SEPARATOR ', ') AS authors')
->where('title LIKE %jerzy%')
->orWhere('name LIKE %jerzy%')
->orWhere('authors LIKE %jerzy%')
->group('a.uid');
請檢查上面的代碼。 我不知道authors LIKE %jerzy%'
這樣的authors LIKE %jerzy%'
是否工作。 我的新查詢也是給你結果。 :P
當你的join
S,你需要告訴它不會從連接表中選擇列。
例如:
->join('publishers', 'products.uid_publisher = publishers.uid', **''**)
