so i wanna try to get a filtering tag method, but in the database part is where i get lost, well kind of, because i wrote a raw query that works, but i need the Eloquent result so i can play with the relationships from the model class.
So here is the raw query:
$peticion = DB::select(DB::Raw("SELECT P.id, P.titulo, P.deadline, P.created_at, P.respuesta_id, U.usuario, C.titulo as categoria, C.clase_css as css, TG.Etiqueta
FROM peticiones P
JOIN usuarios U ON U.id = P.usuario_id
JOIN categorias C ON C.id = P.categoria_id
LEFT JOIN (
SELECT PT.peticion_id, T.nombre as Etiqueta
FROM tags T
JOIN peticion_tag PT ON PT.tag_id = T.id
) AS TG ON TG.peticion_id = P.id
JOIN (
SELECT PP.peticion_id
FROM (
SELECT PT.peticion_id, count(PT.peticion_id) AS conteo
FROM peticion_tag PT
WHERE PT.tag_id IN ( $etiquetas )
GROUP BY PT.peticion_id
) PP
WHERE PP.conteo = $len ) AS PPP
ON P.id = PPP.peticion_id
WHERE P.categoria_id = $id ;"));
what it does is that retrieve all the peticiones who has as many tags in it something like this in SO when filtering by tags.
But as i said i need the eloquent so this is my attempt to recreate the raw query:
$pet = Peticion::whereHas('tags', function($q) use ($tags, $len){
$q->whereIn('tag_id', $tags);
})
->where('categoria_id', '=', $id)
->get();
But it returns me all the peticiones who has this tag OR this tag, OR as many has the $tags array this get achieved with the raw query in the
WHERE PP.conteo = $len
but i dont know how to translate to eloquent.
Hope someone can help me, thanks a lot.

I want to view data from mysql in codeigniter based on user who is logged in
but I got an error "A Database Error Occurred". I think I wrote the wrong code
t.USER = $this->session->userdata('user_id');
Here's the code:
function get_rekomen()
{
$query = $this->db->query("SELECT
c.*,
t.produk_id,
t.id_transdet,
t.kategori_id,
t.total_qty,
t.USER
FROM
transaksi_detail AS t
LEFT JOIN
(
SELECT
g.id_produk,
p.slug_produk,
p.foto,
p.foto_type,
p.harga_diskon,
p.diskon,
p.harga_normal,
p.judul_produk,
g.kat_id,
k.judul_kategori
FROM
(
SELECT
MAX(m.id_produk) AS id_produk,
m.kat_id
FROM
produk AS m
GROUP BY
m.kat_id
)
AS g
INNER JOIN
produk AS p
ON p.id_produk = g.id_produk
LEFT JOIN
kategori AS k
ON k.id_kategori = g.kat_id
)
AS c
ON c.kat_id = t.kategori_id
WHERE
t.USER = $ this -> session -> userdata('user_id');
<<// i think here's the problem
ORDER BY
total_qty DESC limit 1")->result();
return $query;
}
and the question is what is the correct code?
Here's one solution, but first make sure on your controller the $this->load->library('session'); is loaded or you can just add in on autoload.php.
Also you must add parameter to your model that will handle the user_id in session, so for example here's your model looks like:
function get_rekomen($user_id) { ...your query here... }
Then on condition using the user_id will be
t.USER = $user_id;
So on your controller, you can call your model like:
$user_id = $this->session->userdata('user_id');
$this->ModelClass->get_rekomen($user_id);
Additional: On your login phase, if the user success from logging in, the you must set the user data on session such as this $this->session->set_userdata('user_data', $session_data);
Hope this helps!
Maybe you can use this. You need to define $user_id first before adding them to WHERE statement...
$user_id = $this->session->userdata('user_id');
$sql = "SELECT c.*, t.produk_id, t.id_transdet, t.kategori_id, t.total_qty, t.USER
FROM transaksi_detail AS t
LEFT JOIN(SELECT g.id_produk, p.slug_produk, p.foto, p.foto_type, p.harga_diskon, p.diskon, p.harga_normal, p.judul_produk, g.kat_id, k.judul_kategori
FROM(SELECT MAX(m.id_produk) AS id_produk, m.kat_id
FROM produk AS m
GROUP BY m.kat_id)
AS g
INNER JOIN produk AS p ON p.id_produk = g.id_produk
LEFT JOIN kategori AS k ON k.id_kategori = g.kat_id)
AS c ON c.kat_id = t.kategori_id
WHERE t.USER = '$user_id'
ORDER BY total_qty DESC limit 1";
$query = $this->db->query($sql);
return $query->result();
Hope this can help you...
Good morning -
This is my first post here, after many years using SO as a very useful resource.
I've run into a problem with a complex (for me) query I'm pulling together for a wordpress site running woocommerce to process orders. I'm trying to add a filter to the order list which filters orders which contain products in a particular product category.
I'm afraid I've gotten in over my head with this query which joins a variety of meta tables on inner queries in order to get at the information I need in order to determine the product's category.
The problem is that I can't get the scoping rules to work in order to access required outer table information in the inner queries.
The query is:
SELECT SQL_CALC_FOUND_ROWS
wp_ot6q6i_posts.ID
FROM
wp_ot6q6i_posts
WHERE
1 = 1 AND YEAR(wp_ot6q6i_posts.post_date) = 2015 AND MONTH(wp_ot6q6i_posts.post_date) = 12 AND wp_ot6q6i_posts.post_type = 'shop_order' AND(
(
wp_ot6q6i_posts.post_status = 'wc-pending' OR wp_ot6q6i_posts.post_status = 'wc-processing' OR wp_ot6q6i_posts.post_status = 'wc-on-hold' OR wp_ot6q6i_posts.post_status = 'wc-completed' OR wp_ot6q6i_posts.post_status = 'wc-cancelled' OR wp_ot6q6i_posts.post_status = 'wc-refunded' OR wp_ot6q6i_posts.post_status = 'wc-failed'
)
) AND EXISTS(
SELECT
t2.PROD_ID
FROM
(
SELECT
wp_ot6q6i_woocommerce_order_itemmeta.meta_value AS PROD_ID
FROM
wp_ot6q6i_woocommerce_order_items
LEFT JOIN
wp_ot6q6i_woocommerce_order_itemmeta
ON
wp_ot6q6i_woocommerce_order_itemmeta.order_item_id = wp_ot6q6i_woocommerce_order_items.order_item_id
WHERE
wp_ot6q6i_woocommerce_order_items.order_item_type = 'line_item' AND wp_ot6q6i_woocommerce_order_itemmeta.meta_key = '_product_id' AND wp_ot6q6i_posts.ID = wp_ot6q6i_woocommerce_order_items.order_id
) t1
INNER JOIN
(
SELECT DISTINCT
wposts.ID AS PROD_ID
FROM
wp_ot6q6i_posts wposts
LEFT JOIN
wp_ot6q6i_postmeta wpostmeta
ON
wposts.ID = wpostmeta.post_id
LEFT JOIN
wp_ot6q6i_term_relationships
ON
(
wposts.ID = wp_ot6q6i_term_relationships.object_id
)
LEFT JOIN
wp_ot6q6i_term_taxonomy
ON
(
wp_ot6q6i_term_relationships.term_taxonomy_id = wp_ot6q6i_term_taxonomy.term_taxonomy_id
)
WHERE
wp_ot6q6i_term_taxonomy.taxonomy = 'product_cat' AND wp_ot6q6i_term_taxonomy.term_id IN(
SELECT
term_id
FROM
`wp_ot6q6i_terms`
WHERE
slug = 'preorder'
)
ORDER BY
wpostmeta.meta_value
) t2
ON
t1.PROD_ID = t2.PROD_ID
)
ORDER BY
wp_ot6q6i_posts.post_date
DESC
LIMIT 0, 20
And the error I'm getting is:
1054 - Unknown column 'wp_ot6q6i_posts.ID' in 'where clause'
Thanks all for your help. I ended up going in a different direction to solve this problem, one I'm more comfortable with as a dev...I'm pulling the fixed list of items from the last join and building a query in code that has a series of more simple queries in the where clause, thereby avoiding the whole Exists approach.
Thanks again for your help.
In a catalog, I have products and articles. Articles are variants of products.
In a catalog, products are sorted in categories and a product can be one or many times in a catalog.
I'd like to get articles of a catalog, but my articles aren't assigned directly to the catalog, only products are.
I'd like to construct the following SQL using Doctrine's query builder:
SELECT a.code, a.productCode, a.name
FROM Article a
INNER JOIN (
SELECT p.code
FROM Product p
WHERE p.catalogCode = 'MYCODE'
GROUP BY p.code
ORDER BY p.code ASC
) AS results ON results.productCode = a.productCode
This query works in MySQL. I tried to do it in the Repository of my entity, but I have an error :
public function findArticlesByCatalog($catatlogCode)
{
return $this->getEntityManager()
->createQuery(
'SELECT a.code, a.productCode, a.name
FROM AppBundle:Article a
INNER JOIN (
SELECT p.code
FROM AppBundle:CatalogProduct p
WHERE p.catalogCode = :code
GROUP BY p.code
ORDER BY p.code ASC
) AS results ON results.productCode = a.productCode'
)
->setParameter('code', $catatlogCode)
->getResult();
}
Error (just after INNER JOIN) :
[Semantical Error] line 0, col 81 near '(
SELECT': Error: Class '(' is not defined.
So, I'd like to construct it using Doctrine's query builder in my Controller.
I started something but I don't know to finish it...
$repository = $em->getRepository('AppBundle:Article');
$qb = $repository->createQueryBuilder('a');
$qb->select(array('a.code', 'a.productCode', 'a.name'))
->innerJoin(
'AppBundle:CatalogProduct', 'p',
'WITH',
$qb->select('p.code')
->where(
$qb->expr()->eq('p.catalogCode', ':code')
)
->setParameter('code', $catCode)
->groupBy('p.code')
->orderBy('p.code', 'ASC')
)
// ...
How to specify the rest of the query ?
AS results ON results.productCode = a.productCode'
Thanks for your help !
I found the right way to do this.
I rewrote my SQL to do the same that my first one in order to do it easily with query builder.
So, my first SQL :
SELECT a.code, a.productCode, a.name
FROM Article a
INNER JOIN (
SELECT p.code
FROM Product p
WHERE p.catalogCode = 'MYCODE'
GROUP BY p.code
ORDER BY p.code ASC
) AS cat_art ON cat_art.productCode = a.productCode
...has the same results that this one :
SELECT DISTINCT a.code, a.productCode, a.name
FROM Article a
JOIN Product p ON a.productCode = p.code
WHERE p.code IN (
SELECT p.code
FROM Product p
WHERE p.catalogCode = 'MYCODE'
GROUP BY p.code
ORDER BY p.code ASC
)
With query builder, we should write 2 queries with 2 different query builders :
# It is very important here to name it "p2", not "p" because,
# in the main query, there is already "p"
$qb2 = $em->getRepository('AppBundle:CatalogProduct')->createQueryBuilder('p2');
$subQuery = $qb2->select('p2.code')
->where(
$qb2->expr()->eq('p2.catalogCode', ':code')
)
->groupBy('p2.code')
->orderBy('p2.code', 'ASC');
# main query
$qb = $em->getRepository('AppBundle:Article')->createQueryBuilder('a');
$query = $qb->select(array('DISTINCT a.code', 'a.productCode', 'a.name', 'p.code AS productCode'))
->join('AppBundle:CatalogProduct', 'p', 'WITH', 'a.productCode = p.code')
->where(
$qb->expr()->in(
'p.code',
$subQuery->getDQL()
)
)
// Parameter used in subquery must be set in main query.
->setParameter('code', $catCode)
->getQuery();
i have got over one milion record in my database table.
When I use like is very slowly, when i use match against they lost some records.
I create help table:
tag_list
tag_id
tag_name
tag_rel_message
tag_id
messag_id
messages
message_id
message_text
in tag_list i add all words of $message_text - explode(" ", $message_text);
My new query is:
SELECT m.*
FROM tag_rel_messages trm
INNER JOIN messages m ON (trm.message_id = m.message_id)
INNER JOIN tag_list tl ON (trm.tag_id=tl.tag_id
WHERE tl.tag_name REGEXP 'pionas' AND tl.tag_name REGEXP 'website'
GROUP By trm.message_id
But not display any records.
What's wrong with this query?
Maybe i should use something other than REGEXP?
Thanks for help
I'm not sure how one column could match two things at the same time! You can use OR in place of AND, or you can use a single call to REGEXP.
SELECT m.*
FROM tag_rel_messages trm
INNER JOIN messages m ON (trm.message_id = m.message_id)
INNER JOIN tag_list tl ON (trm.tag_id=tl.tag_id
WHERE tl.tag_name REGEXP 'pionas|website'
GROUP By trm.message_id
You need to join with the tag_list and tag_rel_message tables twice to match two different tags.
SELECT m.*
FROM messages AS m
JOIN tag_rel_messages AS trm1 ON m.message_id = trm1.message_id
JOIN tag_list AS t1 ON t1.tag_id = trm1.tag_id
JOIN tag_rel_messages AS trm2 ON m.message_id = trm2.message_id
JOIN tag_list AS t2 on t2.tag_id = trm2.tag_id
WHERE t1.tag_name = 'pionas' AND t2.tag_name = 'website'
Another way to do it is to join with either tag, and count the number of results per message
SELECT m.*
FROM messages AS m
JOIN tag_rel_messages AS trm ON m.message_id = trm.message_id
JOIN tag_list AS t ON t1.tag_id = trm.tag_id
WHERE t.tag_name IN ('pionas', 'website')
GROUP BY m.message_id
HAVING COUNT(*) = 2
This second form is a little easier to generalize to any number of tags. Put all the tags in the IN clause, and change the HAVING clause to match the number of tags.
$words = array('pionas', 'website');
$tags_id = array();
foreach ($words as $key => $val) {
$sql = "SELECT tag_id FROM tag_list WHERE tag_name LIKE '%".$val."%'";
$records = $db->query($sql);
$tags_id[$key] = array_column($records, "tag_id");
}
$inner_array = array();
foreach ($tags_id as $k => $v) {
$short_name = "trm_".$k;
$inner_array[] = " INNER JOIN tag_rel_message as ".$short_name." ON ( ".$short_name.".message_id = m.message_id AND ".$short_name.".tag_id IN (".implode(", ", $v).")) ";
}
$sql = "SELECT DISTINCT m.* FROM messages m".implode(" ", $inner_array);
I think this is the same:
SELECT * FROM messages WHERE message_text like '%pionas%' AND message_text like '%website%'
SELECT * FROM wp_posts
INNER JOIN wp_term_relationships
ON ( wp_posts.ID = wp_term_relationships.object_id)
INNER JOIN wp_term_relationships
ON wp_term_taxonomy.term_taxonomy_id = wp_term_relationships.term_taxonomy_id
WHERE term_id = 1 AND taxonomy = 'category';
I want to get the list of posts through this query. Can anyone can solve this query?
Hi #steven spielberg:
Your error was that you specified wp_term_relationships twice instead of specifying wp_term_relationships once and wp_term_taxonomy once. Here is a working query:
SELECT * FROM wp_posts
INNER JOIN wp_term_relationships
ON wp_posts.ID = wp_term_relationships.object_id
INNER JOIN wp_term_taxonomy
ON wp_term_taxonomy.term_taxonomy_id =
wp_term_relationships.term_taxonomy_id
WHERE term_id = 1 AND taxonomy = 'category';
However, if you are planning to use that within a .php file for use with WordPress I would recommend you use a different approach, such as using WP_Query and starting with this:
$term = get_term_by('id',1);
$query = new WP_Query(array(
'taxonomy'=>'category',
'term'=>$term->slug,
));
print_r($query->posts);
You can find other arguments for WP_Query on the query_posts() Codex page (the arguments are the same.) There are several other arguments you'll probably want to use to fine-tune your query.
Of course if you must use direct SQL for some reason then at least use the $wpdb object so you don't have to worry about prefixes, like this:
global $wpdb;
$sql = <<<SQL
SELECT * FROM {$wpdb->posts}
INNER JOIN {$wpdb->term_relationships}
ON {$wpdb->posts}.ID = {$wpdb->term_relationships}.object_id
INNER JOIN {$wpdb->term_taxonomy}
ON {$wpdb->term_taxonomy}.term_taxonomy_id =
{$wpdb->term_relationships}.term_taxonomy_id
WHERE 1=1
AND {$wpdb->term_taxonomy}.term_id = 1
AND {$wpdb->term_taxonomy}.taxonomy = 'category'
SQL;
$posts = $wpdb->get_results($sql);
Hope this helps.
