I have a native query in Doctrine, which generate the right SQL, which runs in PostgreSQL. However the Doctrine returns null/empty results.
public count unReadedNotifications(User $user) {
$rsm = new ResultSetMapping();
$sql =
"SELECT count(ele->'status') FROM notification CROSS JOIN LATERAL jsonb_array_elements(items) status(ele) WHERE notification.id = ? and (ele->'status')::jsonb #> '1'";
$query = $this->getEntityManager()->createNativeQuery($sql,$rsm)->setParameter('1', $user->getNotification()->getId());
return $query->getSingleScalarResult();
}
This Doctrine native query returns null.
If I check the profiler I see the generated query is:
SELECT count(ele->'status') FROM notification CROSS JOIN LATERAL jsonb_array_elements(items) status(ele) WHERE notification.id = 21 and (ele->'status')::jsonb #> '1';
If I copy-paste this into pgAdmin it runs and it retrieve the desired "2".
So pgAdmin can gives me the right result, but Doctrine not.
Can somebody see, where and what went wrong?
Doctrine version: 2.6.3, Postgres is 10.

SphinxSearch: 3.3.1
Ubuntu 22.04
PHP 8.1.12
I am trying to use SphinxQL with PHP to find rows where two different categories match, such as:
$db = new PDO('mysql:host=127.0.0.1;port=9306', '', '');
$sql = "SELECT id FROM index,delta,rtindex WHERE category2 > 0 AND category2 = category1 LIMIT 1000 OPTION max_matches=1000";
$stmt = $db->query($sql);
However, I am receiving a syntax error whenever I do this. I thought this query had worked in the past, but I'm just now noticing it in the logs. Is this the correct way to do it, or is there some other way dictated by sphinx's rules?
I'm trying to use UPDATE SELF JOIN and could not seem to get the correct SQL query.
Before the query, I execute this SQL query to get the values:
SELECT DISTINCT ON (purpose) purpose FROM user_assigned_customer
sales_manager
main_contact
representative
administrator
By the time I run this query, it overwrites all the purpose columns:
UPDATE user_assigned_customer SET purpose = (
SELECT 'main_supervisor' AS purpose FROM user_assigned_customer AS assigned_user
LEFT JOIN app_user ON app_user.id = assigned_user.app_user_id
WHERE app_user.role = 'supervisor'
AND user_assigned_customer.purpose IS NULL
AND assigned_user.id = user_assigned_customer.id
)
The purpose column is now only showing when running the first query:
main_supervisor
Wondering if there is a way to query to update SQL Self JOIN with a custom value.
I think I got it with a help of a friend.
UPDATE user_assigned_customer SET purpose = 'main_supervisor'
FROM user_assigned_customer AS assigned_user
LEFT JOIN app_user ON app_user.id = assigned_user.app_user_id
WHERE app_user.role = 'supervisor'
AND user_assigned_customer.purpose IS NULL
AND assigned_user.id = user_assigned_customer.id
I would like to do a subselect in order to do the following postgresql query with the querybuilder:
SELECT i.* FROM internship i
WHERE EXISTS (SELECT iw.*
FROM internship_weeks iw
WHERE i.id = iw.internship)
Does anyone have an idea how to get the same result with queryBuilder? or maybe with DQL?
Thanks for the help !
As example, only for demonstrate HOW-TO use a subquery select statement inside a select statement, suppose we what to find all user that not yet have compile the address (no records exists in the address table):
// get an ExpressionBuilder instance, so that you
$expr = $this->_em->getExpressionBuilder();
// create a subquery
$sub = $this->_em->createQueryBuilder()
->select('iw')
->from(IntershipWeek::class, 'iw')
->where('i.id = iw.intership');
$qb = $this->_em->createQueryBuilder()
->select('i')
->from(Intership::class, 'u')
->where($expr->exists($sub->getDQL()));
return $qb->getQuery()->getResult();
Hope this help
I need help to build a Laravel query from my raw SQL Query. I tried many way and did not find my Luck. Can anybody help me? My Raw SQL code is given bellow.
SELECT exams. * , count( question_details.exam_id ) AS qus_enter
FROM exams
INNER JOIN question_details ON exams.id = question_details.exam_id GROUP BY exams.id
This is what I've tried:
$examListsID = DB::table('exams')
->join('question_details', function($join) {
$join->on('exams.id', '=', 'question_details.exam_id as qus_enter');
})
->whereraw('count(qus_enter) = exams.total_question')
->select('exams.id as examID','qus_enter','exams.total_question')
->count('qus_enter')
->groupby('exams.id')
->get();
$examLists = Addexam::where('id','=',$examListsID->examID)
And I Get this Error:
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'as qus_enter where count(qus_enter) = exams.total_question' at line 1 (SQL: select count(qus_enter) as aggregate from exams inner join question_details on exams.id = question_details.exam_id as qus_enter where count(qus_enter) = exams.total_question)
$result = DB::table('exams')->join('question_details','exams.id','=','question_details.exam_id')->select([
exams.*,
DB::raw('count( question_details.exam_id ) AS qus_enter')
])->GroupBy('exams.id')->get()
Hope this helps

I have an Oracle query that I ported to PostgreSql:
UPDATE "SPD_PG"."TT_SPLDR_11A2F324_29"
SET "SECT_ORDER" = MAX("SECTIONS"."SECT_ORDER")+1 FROM "SPD_PG"."SECTIONS"
INNER JOIN "SPD_PG"."META_SECTIONS" ON ("SECTIONS"."META_SECT_ID"="META_SECTIONS"."META_SECT_ID")
WHERE ("META_SECTIONS"."META_SECT_ORDER"="TT_SPLDR_11A2F324_29"."META_SECT_ORDER"-1)
AND ("SECTIONS"."DOC_ID"="TT_SPLDR_11A2F324_29"."DOC_ID")
AND ("TT_SPLDR_11A2F324_29"."META_SECT_ORDER">0)
This give me: ERROR: cannot use aggregate function in UPDATE, seems PostgreSql doesn't support MAX in Update statements.
However if I rewrite the query as follows:
UPDATE "SPD_PG"."TT_SPLDR_11A2F324_29"
SET "SECT_ORDER" = "MAX_VALUE" FROM (
SELECT MAX("SECTIONS"."SECT_ORDER")+1 AS "MAX_VALUE" FROM "SPD_PG"."SECTIONS"
INNER JOIN "SPD_PG"."META_SECTIONS" ON ("SECTIONS"."META_SECT_ID"="META_SECTIONS"."META_SECT_ID")
WHERE ("META_SECTIONS"."META_SECT_ORDER"="TT_SPLDR_11A2F324_29"."META_SECT_ORDER"-1)
AND ("SECTIONS"."DOC_ID"="TT_SPLDR_11A2F324_29"."DOC_ID")
AND ("TT_SPLDR_11A2F324_29"."META_SECT_ORDER">0)
) "TBL_ALIAS"
it says ERROR: subquery in FROM cannot refer to other relations of same query level.
So I can't figure out how to write this query.
Try this:
UPDATE "SPD_PG"."TT_SPLDR_11A2F324_29"
SET "SECT_ORDER" = (SELECT MAX("SECTIONS"."SECT_ORDER")+1
FROM "SPD_PG"."SECTIONS"
INNER JOIN "SPD_PG"."META_SECTIONS" ON ("SECTIONS"."META_SECT_ID"="META_SECTIONS"."META_SECT_ID")
WHERE ("META_SECTIONS"."META_SECT_ORDER"="TT_SPLDR_11A2F324_29"."META_SECT_ORDER"-1)
AND ("SECTIONS"."DOC_ID"="TT_SPLDR_11A2F324_29"."DOC_ID")
AND ("TT_SPLDR_11A2F324_29"."META_SECT_ORDER">0)
)
