I'm using $wpdb to connect to a different database than my wordpress one like this:
$newdb = new wpdb(DB_NEW_USER, DB_NEW_PASSWORD, DB_NEW_NAME, DB_NEW_HOST);
I need to insert multiple rows into the database.
I used the code from this answer: Wordpress $wpdb. Insert Multiple Records.
To run the query, I use this line:
$newdb->query( $newdb->prepare("$query", $values));
When I do echo $query, this is the result: (there are more than 3 columns, but I shortened if for times sake)
INSERT INTO table (column1, column2, column3) VALUES ('%s', '%s', '%s')
When I var_dump($values), it returns an array with the same amout of strings as I have columns.
When I run the query, I get the following error:
WordPress database error: [Query was empty]
I tried selecting from the database in a similar fashion and it did work, so my connected to the db is working.
What am I doing wrong?
If anyone can help me I would really appreciate it.
Are you sure your query look like this?
$metakey = "Harriet's Adages";
$metavalue = "WordPress' database interface is like Sunday Morning: Easy.";
$wpdb->query( $wpdb->prepare(
"
INSERT INTO $wpdb->postmeta
( post_id, meta_key, meta_value )
VALUES ( %d, %s, %s )
",
array(
10,
$metakey,
$metavalue
)
) );

I've been trying to use product search in the admin area, it used to work fine, now i get this errors:
SELECT DISTINCT posts.ID as product_id, posts.post_parent as parent_id FROM mu05iq_posts posts
LEFT JOIN mu05iq_wc_product_meta_lookup wc_product_meta_lookup ON posts.ID = wc_product_meta_lookup.product_id
LEFT JOIN mu05iq_wc_product_meta_lookup parent_wc_product_meta_lookup
ON posts.post_type = 'product_variation' AND parent_wc_product_meta_lookup.product_id = posts.post_parent
WHERE posts.post_type IN ('product','product_variation')
AND ( ( ( posts.post_title LIKE '%fiber%') OR ( posts.post_excerpt LIKE '%fiber%') OR ( posts.post_content LIKE '%fiber%' ) OR ( wc_product_meta_lookup.sku LIKE '%fiber%' ) OR ( wc_product_meta_lookup.sku = "" AND parent_wc_product_meta_lookup.sku LIKE '%fiber%' ) ))
ORDER BY posts.post_parent ASC, posts.post_title ASC
WordPress database error: [Unknown column '1' in 'where clause']
SELECT COUNT( 1 ) FROM mu05iq_postmeta WHERE post_id IN( SELECT ID FROM mu05iq_posts WHERE post_type = 'product' ) && meta_value = "1" AND meta_key = '_yoast_wpseo_is_cornerstone'
If anyone has any ideas i would appreciate it.
Thanks and regards.
If someone is experiencing this issue, it's a digital ocean managed database setting, when you create a database cluster it sets up some settings in Global SQL Mode, just remove ANSI_QUOTES. That fixed my issue.
What I want to achieve is display the number of posts which have particular meta key or value I am getting a list of posts and meta key and value but don't know how to display them I'm storing data using repeatable fields. Storing work properly.
Now, for example, I have age meta value in two posts so how can I count no of a post with age. Age = No of post 2.
My Code :
global $wpdb;
$query = $wpdb->get_results("SELECT * FROM {$wpdb->prefix}postmeta WHERE (meta_key = 'repeatable_fields') ");
$array = wp_json_encode($query);
print_r($array);
Outout :
[{"meta_id":"312","post_id":"108","meta_key":"repeatable_fields","meta_value":"a:2:{i:0;a:2:{s:4:\"name\";s:6:\"Zaheer\";s:5:\"phone\";s:3:\"123\";}i:1;a:2:{s:4:\"name\";s:6:\"Sageer\";s:5:\"phone\";s:11:\"09190219218\";}}"},{"meta_id":"323","post_id":"121","meta_key":"repeatable_fields","meta_value":"a:2:{i:0;a:2:{s:9:\"iif_label\";s:4:\"City\";s:11:\"iif_details\";s:7:\"karachi\";}i:1;a:2:{s:9:\"iif_label\";s:3:\"Age\";s:11:\"iif_details\";s:2:\"12\";}}"},{"meta_id":"329","post_id":"126","meta_key":"repeatable_fields","meta_value":"a:1:{i:0;a:2:{s:9:\"iif_label\";s:3:\"Age\";s:11:\"iif_details\";s:2:\"12\";}}"},{"meta_id":"332","post_id":"128","meta_key":"repeatable_fields","meta_value":"a:3:{i:0;a:2:{s:9:\"iif_label\";s:7:\"Country\";s:11:\"iif_details\";s:8:\"Pakistan\";}i:1;a:2:{s:9:\"iif_label\";s:4:\"City\";s:11:\"iif_details\";s:9:\"Islamabad\";}i:2;a:2:{s:9:\"iif_label\";s:3:\"Age\";s:11:\"iif_details\";s:2:\"12\";}}"}]
You could try something like this:
$count_age = $wpdb->get_col( $wpdb->prepare(
"
SELECT count(meta_id)
FROM {$wpdb->prefix}postmeta
WHERE meta_value LIKE '%%%s%%'
",
'Age'
));

I know that similar question was asked 3 years ago (Doctrine2 Order By before Group By) but maybe from that time something changed.
i have 2 entity propertes:
orderId
orderUpdateDate
both as a pair are set to be unique, but for listing I need last update date so sorting should be
order by orderUpdateDate DESC
and then grouped by orderId so I have orders only once.
group by orderId
problem is such that when I paste both in one query in query builder I got random listing of orders
To achieve such a result you'd have to end up with following SQL query:
SELECT n.id, n.update_date
FROM (
SELECT o.id, o.update_date
FROM orders o
ORDER BY o.update_date DESC
) n
GROUP BY n.id;
Unfortunately Doctrine's DQL doesn't support nested queries in FROM clause. However, it allows you to create a custom, native SQL query that can be mapped by ORM:
$rsm = new ResultSetMappingBuilder($em);
$rsm->addRootEntityFromClassMetadata('MyProject\\Order', 'o');
$sql = sprintf('SELECT %s FROM (SELECT ...) GROUP BY ...', $rsm->generateSelectClause());
$query = $em->createNativeQuery($sql, $rsm);
$result = $query->getResult();
---- Done with Symfony2.3.1 and Doctrine2 ----
Sorry, i hope i was not too stupid to find a suitable solution for my problem. I try to build a Query for hours.
SELECT * FROM product
WHERE product_id in
(
SELECT product_id from (
SELECT count(*) as result_amount, product_id FROM product_x_attribut
JOIN productattribut on productattribut_id = productattribut.id
WHERE (
productkey = "price" and
stringType = "premium"
) or (
productkey = "size" and
stringType = "S"
)
GROUP BY product_id
HAVING result_amount = 2
) as temp
)
GROUP BY product_id
ORDER BY p0_.name ASC
This is the SQL which works fine in phpmyAdmin.
This can be seen like
Select * from abc where abc.x in ( Select * from ( select * from ) as abcd )
So there is one core query, i call it subSubQuery, the second query around the core will be called subQuery and the outer Query is just the outer Query, no a Subquery.
I could build the subSubQuery with Doctrine2.
But i cannot built the subQuery like this
Select product_id from ( $subSubQuery->getQuery()->getDQL() )
I want to do the subQuery like this
$subQuery = $repositoryProduct->createQueryBuilder('product');
$subQuery->add('select', 'product_id');
$subQuery->add('from',$subSubQuery->getDQL() );
// However to set an alias is a miracle for me, this didnt work off course
$subQuery->add('as','tmp' );
This is the subQuery.
I also cannot build the outer Query
Select * from abc where abc.x in ( $subQuery->getQuery()->getDQL() )
I want to do this like this
$query->where(
$query->expr()->in('product.id', $subQuery->getDQL() )
);
But i try to build this with Doctrine2 like this:
I am so down, i tried ->getSQL(), ->getDQL(), i tried as much as i was able to detect as a suitable tiny step to a solution for this problem and i has tried as much keyword in google as my finger were able to write... I hope someone could help me to find a solution...
Thanks a lot to each helpful advise.
I know that statements like this work:
$qbGames->andWhere($qbGames->expr()->in('game.id',$qbGameId->getDQL()));
Your question is kind of hard to follow. Consider using pastebin to show all your mappings as they currently exist. And then maybe presenting a simplieid query?
My $qbGameId query was built with:
$qbGameId = $em->createQueryBuilder();
$qbGameId->addSelect('distinct gameGameId.id');
$qbGameId->from('ZaysoCoreBundle:Event','gameGameId');
// Assorted joins and where conditions
I am doing the following:
$type = 'attachment';
$images = $wpdb->get_results($wpdb->prepare('
SELECT p.*
FROM wp_%d_posts p
WHERE p.post_parent =%d
AND p.post_type = "%s"
', $blog_id, $page->ID, $type),OBJECT);
var_dump($images);
If I remove the line 'AND p.post_type = "%s"' then I get results returned, otherwise I get an empty array returned. If I run the query direct against the DB in a mysql client, I get results.
There is no error, just an empty result set. I am doing similar queries throughout my file and they are working so I'm not looking for "don't do it like that" style replies. I just need to understand why this isn't working and fix it.

Do not Quote "%s". From the WordPress site, "Notice that you do not have to worry about quoting strings. Instead of passing the variables directly into the SQL query, use a %s placeholder for strings and a %d placedolder for integers."
Example:
$wpdb->query( $wpdb->prepare( "UPDATE $wpdb->posts SET post_title = %s WHERE ID = %d", $var, $id ) );
