I am doing like this sql into zend framework sql pattern.
SELECT
jobs . *,
c.id AS cid,
c.name AS name,
c.companyImage AS companyImage,
c.logo AS logo,
count(app.userId) AS t_app,
app.applyStatus AS applyStatus,
app.userId AS appUserId
FROM
jobs
LEFT JOIN
companies AS c ON jobs.companyName = c.id
LEFT JOIN
applicants AS app ON jobs.id = app.jobId AND app.applyStatus = 1
WHERE
jobs.ownerId = 16 AND jobs.draftId != 0
GROUP BY jobs.id
ORDER BY jobs.id DESC
LIMIT 3
For this sql I already write this code for zend framework 2
$adapter = $this->tableGateway->getAdapter();
$sql = new Sql($adapter);
$select = $sql->select();
$select->from('jobs')
->join(array('c' => 'companies'), 'jobs.companyName = c.id', array('cid' => 'id', 'name', 'companyImage', 'logo'), 'left')
->join(array('app' => 'applicants'), ' jobs.id = app.jobId AND app.applyStatus = 1', array('t_app' => new Expression('count(app.userId)'), 'applyStatus', 'appUserId' => 'userId'), 'left')
->where("jobs.ownerId ={$userId} AND jobs.draftId != 0")
->group('jobs.id')
->order('jobs.id DESC')
->limit(3);
$statement = $sql->getSqlStringForSqlObject($select);
$results = $adapter->query($statement, $adapter::QUERY_MODE_EXECUTE);
but does not work properly and its give a message like below.
SQLSTATE[42S22]: Column not found: 1054 Unknown column '1' in 'on clause'
The issue is this part:
app.applyStatus = 1
The framework is escaping 1 as if it were a column name, 1.
You need to enclose this part in an Expression too
new Expression('jobs.id = app.jobId AND app.applyStatus = 1')
I think the use of Expressions in the 'ON' parameter of the join method may depend on the version of ZF2 you are using, I think it was added 2.1+
Building on this answer. If you also want your table & column identifiers to be escaped, use this syntax:
use Zend\Db\Sql\Expression;
...
$onExpression = new Expression('? = ? AND ? = ?',
['jobs.id', 'app.jobId', 'app.applyStatus', 1],
[Expression::TYPE_IDENTIFIER, Expression::TYPE_IDENTIFIER,
Expression::TYPE_IDENTIFIER, Expression::TYPE_LITERAL]
);
$select->from('jobs')
->join(array('app' => 'applicants'), $onExpression, array('t_app' => new Expression('count(app.userId)'), 'applyStatus', 'appUserId' => 'userId'), 'left');
The Expression constructor accepts the string, then arguments, then argument types.
public function __construct($expression = '', $parameters = null, array $types = [])
This will create a security issue. Zf2 changes your query to this:
Select * from tableA inner join tableB
on `tableA`.`column` = `tableB`.`column`
AND `tableB`.`column` = `1`
It adds
`
to each part for security issues! By using new Expression you are bypassing it and if you get applyStatus from user entry, get sure about its filtering!

In Codeigniter3, I have the following select join model:
public function get_post()
{
$q = $this->db->select('posts.id, posts.active, posts.title, posts.close_date, users.name')
->from('posts')
->join('users', 'posts.user_id = users.id', 'left')
->where('posts.active','1')
->where(['posts.active' => '1', 'posts.close_date >=' => date('Y-m-d')])
->order_by('posts.updated_at', 'DESC')->get();
return $q;
}
How can I list all posts with count posts for each user (count only posts where posts.active = 1 and posts.close_date >= current date)?
If CI can't do the job, please give me the sql query.
Here you go:
With complex queries like this, the best way is to store the sql script in a string variable and use $this->db->query() to execute it.
This query is in MySQL:
public function get_posts() {
$sql = "
SELECT `posts`.`id`, `posts`.`active`, `posts`.`title`, `posts`.`close_date`, users.name, COUNT(`posts`.`user_id`) AS `active_post_count`
FROM `posts`
LEFT JOIN `users` ON `posts`.`user_id` = `users`.`id`
WHERE `posts`.`active` = ?
AND `posts.close_date` >= ?
ORDER BY `posts`.`updated_at` DESC;
";
$now = new DateTime('now');
$binds = [1, $now->format('Y-m-d H:i:s')];
return $this->db->query($sql, $binds)->result_array();
}
Here's a sample code on how to access the post count:
$this->Your_model->get_posts()[0]['active_post_count'];
See CodeIgniter's docs on Generating Query Results:
If you want the result as an object instead, use result_object() over result_array().
How to get value from custom profile field in moodle?
i want to include the profile field in user.php
If you want to load all the user profile fields, then you can start with a user object
$user = $DB->get_record('user', array('id' => $userid));
and then call
profile_load_custom_fields($user);
to fill in the $user->profile with an array of all the custom fields.
Alternatively, you can get the contents of a single profile field via:
$sql = "SELECT ud.data
FROM {user_info_data} ud
JOIN {user_info_field} uf ON uf.id = ud.fieldid
WHERE ud.userid = :userid AND uf.shortname = :fieldname";
$params = array('userid' => $userid, 'fieldname' => 'NameOfCustomField');
$fieldvalue = $DB->get_field_sql($sql, $params);
Note this code is written off the top of my head and untested, so it may have some typos in it.
You can use:
$Data = $USER->profile['YourCustomField'];
I finally made it!!!
$sql = 'SELECT DISTINCT u.id AS userid, u.username, uif.shortname, uid.data FROM prefix_user u JOIN prefix_user_info_data as uid on uid.userid = u.id JOIN prefix_user_info_field as uif on uid.fieldid = uif.id JOIN prefix_user_enrolments ue ON ue.userid = u.id JOIN prefix_enrol e
ON e.id = ue.enrolid JOIN prefix_role_assignments ra ON ra.userid = u.id JOIN prefix_context ct ON ct.id = ra.contextid AND
ct.contextlevel = 50 JOIN prefix_course c ON c.id = ct.instanceid AND e.courseid = c.id JOIN prefix_role r ON r.id = ra.roleid
where uif.shortname = \'fieldname\' and u.id ='.$userid;
$records = $DB->get_recordset_sql($sql, array(), $params=null, $limitfrom=0, $limitnum=0);
foreach($records as $record){
$user['fieldname'] = $record->data;
}
custom fields are stored in 'user_info_field' table and data for each field and user are stored in 'user_info_data' table then you should know your fieldid in database and select data based on this id:
$field = $DB->get_record('user_info_field', array('shortname' => 'customfieldshortname'));
$fieldvalues = $DB->get_records('user_info_data',array('fieldid' => $field->id));
i hope my solutions help anybody:
need this lib
require_once($CFG->dirroot.'/user/profile/lib.php');
and now you can use:
profile_load_data($USER);
$USER->profile_field_%your_field_name%
example $USER->profile_field_HaveAnotherGradeBook;
SELECT A.FirstName, A.LastName, B.PatientId, B.RoomNumber, B.AdmissionDate, B.DischargeDate, B.MeasureCategory
FROM DimPatient A, DimPatientStay B
WHERE A.Id = B.PatientId AND A.FirstName = 'Anuj' AND B.MeasureCategory = 'ED'
hi some updation for this
i solved this prob by
MODELNAME.find_by_sql("your sql query")
You can try this to find the result from sql query in Rails
query_params = Hash.new
sql_query = "SELECT A.FirstName, A.LastName, B.PatientId, B.RoomNumber, B.AdmissionDate, B.DischargeDate, B.MeasureCategory
FROM DimPatient A, DimPatientStay B
WHERE A.Id = B.PatientId AND A.FirstName = :first_name AND B.MeasureCategory = :measure_category"
query_params[:first_name] = first_name
query_params[:measure_category] = measure_category
#query_results = ActiveRecord::Base.connection.select_all(
ActiveRecord::Base.send("sanitize_sql_array",[sql_query, query_params] )
)
I guess you could try:
ActiveRecord::Base.connection().execute(#your_sql_here)
Suppose A is one class and B is another, you should use includes as following:
A.includes(:b).where(...) # add you condition in where

I have follow query
notes = Note.where('notes.id IN
(
SELECT "notes"."id" FROM "notes"
WHERE "notes"."circle_id" = ?
)
OR notes.id IN
(
SELECT "notes"."id" FROM "notes"
INNER JOIN "circles_dreams"
ON "circles_dreams"."dream_id" = "notes"."dream_id"
WHERE "circles_dreams"."circle_id" = ?
)', #circle.id, #circle.id)
How to simplify this query?
Thanks.
First of all you can collect all needed notes id.
I supposed to think what you already have relations between Note and CirclesDream
note_ids = Note.where(circle_id: #circle.id).pluck(:id) # your first SELECT
dream_ids = CirclesDream.where(id: #circle.id).pluck(:note_id) # your second SELECT
notes_ids = note_ids | dreams_ids # combine them
notes = Note.where(id: notes_ids) # Now your
upd: I've just fixed typo. Changed id to note_id in second request
Try this
note_ids = Note.where('circle_id = ?', #circle.id).pluck(:id)
dream_note_ids = Note.joins(:circle_dreams).where('circle_dreams.circle_id = ?', #circle.id).plunk(:note_id)
notes_ids = note_ids | dream_note_ids
If your circle_dreams table can contain records having note_id = null, then you have to apply join. So i think this will work in your case....
How would you write this line in the "rails way"?
unique_attendees = CourseSessionsUser.count_by_sql(["SELECT count(DISTINCT csu.user_id) AS count_user_id FROM course_sessions_users csu, course_sessions cs WHERE cs.course_id = ? AND csu.course_session_id = cs.id"], #course.id)
The query itself is:
SELECT count(DISTINCT csu.user_id) AS count_user_id
FROM course_sessions_users csu,
course_sessions cs
WHERE cs.course_id = ?
AND csu.course_session_id = cs.id
Use count method of the rails
count = CourseSessionsUser.count('csu.user_id',
:distinct => true, :conditions => ["cs.course_id = ?", #course.id]
:joins => "cs LEFT JOIN course_sessions_users csu ON cs.id = csu.course_session_id")
This will return directly non zero integer if condition matches otherwise return zero
