I am trying to get this inner join to show output the the title and date. Is only returning the sql object that gives details on object. this is result. I can access num_rows but just gives me int(11) for the number of records, don't know how to access the info in the fields.
This is the result.
object(mysqli_result)#6 (5) { ["current_field"]=> int(0) ["field_count"]=> int(2) ["lengths"]=> NULL ["num_rows"]=> int(11) ["type"]=> int(0) }
Thanks for help.
$sql = "SELECT title, artist_name";
$sql .= " FROM follows";
$sql .= " INNER JOIN artworks";
$sql .= " ON follows.user_id_followed = artworks.artist_id";
$sql .= " AND follows.user_id_follower='12'";
$result_set = $database->query($sql);
echo var_dump($result_set);
you need a WHERE
$sql = "SELECT title, artist_name";
$sql .= " FROM follows";
$sql .= " INNER JOIN artworks";
$sql .= " ON follows.user_id_followed = artworks.artist_id";
$sql .= " WHERE follows.user_id_follower='12'";
You also probably want LEFT JOIN not INNER JOIN`

I am curious as to how best achieve this.
wpdb query 1:
$results = $wpdb->get_results(
"SELECT *
FROM $table_name
WHERE user_id = '$userid';"
);
I then want to do another wpdb query on a separate table using $results->post_id in the WHERE part of the query such as:
$results2 = $wpdb->get_results(
"SELECT *
FROM $table_name2
WHERE user_id = '$results->post_id' && type = '$type';"
);
I am conscious that $results will be an array so I don't think the above will work directly and some sort of compound "for each" seems cumbersome.
What are my options please?
Update example based on Jarlh's comment
$userid = get_current_user_id();
global $wpdb;
$table_name = $wpdb->prefix . 'postmeta';
$table2_name = $wpdb->prefix . 'posts';
$rewards_results = $wpdb->get_results(
"SELECT *
FROM $table_name
WHERE post_id in ("SELECT user_id
FROM $table2_name
WHERE user_id = '$userid';")"
);
Update 2:
$userid = get_current_user_id();
global $wpdb;
$table_name = $wpdb->prefix . 'postmeta';
$table2_name = $wpdb->prefix . 'posts';
$results = $wpdb->get_results(
"SELECT *
FROM $table_name
WHERE ID in (SELECT user_id
FROM $table2_name
WHERE user_id = '$userid')"
);
//return $results;
foreach ($results as $row) {
echo "<td class='dash-2-td'>" . esc_html($row->logo_id) . "</td>";
echo "<td class='dash-2-td'>" . esc_html($row->belongs_to) . "</td>";
echo "</tr>";
}
This is producing no output.
I need to search $table_name->post_id for rows that match $table2_name->ID where user_id = $userid
Update 3: print_r is just showing array(), seems empty
$userid = get_current_user_id();
global $wpdb;
//$table_name = $wpdb->prefix . 'postmeta';
//$table2_name = $wpdb->prefix . 'posts';
$results = $wpdb->get_results(
"SELECT $wpdb->posts.*
FROM $wpdb->posts, $wpdb->postmeta
WHERE $wpdb->posts.ID = $wpdb->postmeta.post_id
AND $wpdb->posts.post_author = $userid
AND $wpdb->postmeta.plan = 3981
");
return $results;
I ended up using wp_query which I had not even considered as an option.
As a solution, you can use INNER JOIN. Also, I'd suggest you to use $wpdb->prepare for escaping values. Here is an example:
$sql = $wpdb->prepare( "SELECT a.*, b.col1, b.col2 FROM $table1 as a INNER JOIN $table2 as b ON a.user_id = b.user_id WHERE a.user_id = %d AND b.type = %s", $user_id, $type );
$entries = $wpdb->get_results( $sql, ARRAY_A );
Hope it helps.
I do search function In raw SQL like this
//test condition variable
if ($param_type != "") {
if($param_type =='SAS'){
$str .= " AND pos.type IN('SAS1','SAS2') ";
}
else if($param_type =='SME'){
$str .= " AND pos.type IN('SME1','SME2') ";
}
else if($param_type =='PT'){
$str .= " AND pos.type IN('PT','PT0') ";
}else{
$str .= " AND pos.type ='$param_type'";
}
}
//SQL
$query =" SELECT * FROM tbl_user AS u INNER JOIN tbl_position AS pos
ON u.user_id = pos.user_id where u.levels IN ('7','8','9') .$str ;" ;
How I can write SQL like this in laravel ?
You can use raw query.
$query = DB::select(SELECT * FROM tbl_user AS u INNER JOIN tbl_position AS pos
ON u.user_id = pos.user_id where u.levels IN ('7','8','9') .$str ;");
Of course then you need to add at the top in your controller use DB;
Anyway Raw queries may be dangerous and it's better to use query builder.
Simple example:
$query = DB::table('tbl_user')
->join('tbl_position','tbl_user.user_id','=','tbl_position.user_id')
->where('something','=','something')
->get();
Query builder: query builder
Reply to my question for who meet problem like me:
Example like this
$query = DB::table('user');
if ($param_type =='PT')
$query->where('pos.type', '=', 1);
}
$result = $query->get();
here is my query i want to execute it as
$query="select * from $post INNER JOIN $postmeta on $postmeta.post_id= $post.ID
where $post .post_status='publish'
and $post .post_type ='task
and $post .post_type='service'
ORDER BY $post .post_date DESC ";
how to execute
Previous a proper sanitize of the var $postmeta and $post you can do this way
Building dinamic query by string concantenation (because var in tabel and column name are not allowed in sql)
$query="select * from " . $post . " INNER JOIN " .
$postmeta . " on " . $postmeta . ".post_id= " . $post .".ID where " .
$post . ".post_status='publish' and " . $post .".post_type ='task' and " .
$post . "post_type='service' ORDER BY " . $post .".post_date DESC ";

I am trying to use all columns for each row from one table (party), and some columns from another (customer).
Ok, here is my code
public function getParty($data = array()) {
$sql = "SELECT party.* , customer.customer_id AS customerID, customer.firstname AS customerFN, customer.lastname AS customerLN, customer.email AS customerEMAIL, customer.ip AS cutomerIP
FROM `" . DB_PREFIX . "party`
JOIN `" . DB_PREFIX . "cutomer`
ON party.cutomer_id = customer.customer_id
WHERE status=3";
$sort_data = array(
'date_added',
'order_id',
'customer_id',
'customerFN',
'customerLN',
'customerEMAIL',
'customerIP',
'description',
'status',
'amount'
);
if (isset($data['sort']) && in_array($data['sort'], $sort_data)) {
$sql .= " ORDER BY " . $data['sort'];
} else {
$sql .= " ORDER BY date_added";
}
if (isset($data['order']) && ($data['order'] == 'DESC')) {
$sql .= " DESC";
} else {
$sql .= " ASC";
}
if (isset($data['start']) || isset($data['limit'])) {
if ($data['start'] < 0) {
$data['start'] = 0;
}
if ($data['limit'] < 1) {
$data['limit'] = 20;
}
$sql .= " LIMIT " . (int)$data['start'] . "," . (int)$data['limit'];
}
$query = $this->db->query($sql);
return $query->rows;
}
And here is the error
Notice: Error: Table 'XXX.cutomer' doesn't exist
Error No: 1146
SELECT party.* , customer.customer_id AS customerID, customer.firstname AS customerFN, customer.lastname AS customerLN, customer.email AS customerEMAIL, customer.ip AS cutomerIP FROM `party` JOIN `cutomer` ON party.cutomer_id = customer.customer_id WHERE status=3 ORDER BY date_added ASC LIMIT 0,10 in /srv/www/htdocs/XXX/system/database/mysql.php on line 49
Maybe I am wrong somewhere, but do not see it

JOIN `" . DB_PREFIX . "cutomer`
Should be
JOIN `" . DB_PREFIX . "customer`
?
Also...
ON party.cutomer_id = customer.customer_id
Should be
ON party.customer_id = customer.customer_id
?
I would search for all instances of cutomer and replace them with customer.
I think it should be
ON party.customer_id = customer.customer_id
instead of
ON party.cutomer_id = customer.customer_id
Please change from
JOIN `" . DB_PREFIX . "cutomer`
To
JOIN `" . DB_PREFIX . "customer`
Ex:
FROM `" . DB_PREFIX . "party`
JOIN `" . DB_PREFIX . "customer`
ON party.cutomer_id = customer.customer_id
WHERE status=3";
Change your SQL stmt to this:
$sql = "SELECT party.* , customer.customer_id AS customerID, customer.firstname AS customerFN, customer.lastname AS customerLN, customer.email AS customerEMAIL, customer.ip AS customerIP
FROM `" . DB_PREFIX . "party`
JOIN `" . DB_PREFIX . "customer`
ON party.customer_id = customer.customer_id
WHERE status=3";
fI have what seems to be a relatively simple AND/OR clause that is giving me a bit of a headache.
$query = "SELECT stv.name,stc.tmplvarid,stc.contentid,stv.type,stv.display,stv.display_params,stc.value";
$query .= " FROM ".$tb1." stc LEFT JOIN ".$tb2." stv ON stv.id=stc.tmplvarid ";
$query .= " LEFT JOIN $tb_content tb_content ON stc.contentid=tb_content.id ";
$query .= " WHERE stv.name='".$region."' AND stc.contentid IN (".implode($cIDs,",").") ";
$query .= " OR stv.name='".$countries."' AND stc.contentid IN (".implode($cIDs,",").") ";
$query .= " AND tb_content.pub_date >= '$pub_date' ";
$query .= " AND tb_content.published = 1 ";
$query .= " ORDER BY stc.contentid ASC;";
I need it to retrieve the values from both $region and $countries. However, the way it is it only returns the value of $countries. If I remove the line with the OR it returns the value of $region, but it won't return both. What am I doing incorrectly?
Try putting brackets around the clauses on either side of the OR. See below:
$query = "SELECT stv.name,stc.tmplvarid,stc.contentid,stv.type,stv.display,stv.display_params,stc.value";
$query .= " FROM ".$tb1." stc LEFT JOIN ".$tb2." stv ON stv.id=stc.tmplvarid ";
$query .= " LEFT JOIN $tb_content tb_content ON stc.contentid=tb_content.id ";
$query .= " WHERE (stv.name='".$region."' AND stc.contentid IN (".implode($cIDs,",").")) ";
$query .= " OR (stv.name='".$countries."' AND stc.contentid IN (".implode($cIDs,",").")) ";
$query .= " AND tb_content.pub_date >= '$pub_date' ";
$query .= " AND tb_content.published = 1 ";
$query .= " ORDER BY stc.contentid ASC;";
Looks like you are missing parentheses, no?
A or B and C or D is ambiguous, you need to use parentheses to make it clear you mean (A or B) and (C or D)
