I have this SQL Query.
SELECT
c.id,
c.name,
c.slug,
sc.id,
sc.name,
sc.slug,
COUNT(bsc.id) AS business_count
FROM
fi_category c
LEFT JOIN
fi_subcategory sc ON c.id = sc.category_id AND (sc.deleted_at IS NULL)
LEFT JOIN (
fi_business b
INNER JOIN
fi_business_subcategory bsc ON b.id = bsc.business_id AND (bsc.deleted_at IS NULL)
INNER JOIN
fi_suburb su ON su.id = b.suburb_id AND su.city_id = 1
) ON sc.id = bsc.subcategory_id
WHERE
(c.deleted_at IS NULL)
GROUP BY
c.id, sc.id
as this type of query is not supported by DQL. i want to use it with Doctrine_RawSql
i tried using it this way.
$q = new Doctrine_RawSql();
$q->select('{c.name}, {c.slug}, {sc.name}, {sc.slug}, {COUNT(bsc.id) AS business_count}');
$q->from('fi_category c LEFT JOIN fi_subcategory sc ON c.id = sc.category_id AND (sc.deleted_at IS NULL) LEFT JOIN (fi_business b INNER JOIN fi_business_subcategory bsc ON b.id = bsc.business_id AND (bsc.deleted_at IS NULL) INNER JOIN fi_suburb su ON su.id = b.suburb_id AND su.city_id = 1) ON sc.id = bsc.subcategory_id');
$q->groupBy('GROUP BY c.id, sc.id');
$q->addComponent('c', 'Model_Category c');
$q->addComponent('sc', 'c.Subcategory sc');
$q->addComponent('bsc', 'sc.BusinessSubcategory bsc');
$q->addComponent('b', 'bsc.Business b');
$q->addComponent('su', 'b.Suburb su');
$q->execute();
this query is not working, which is the correct way of building Doctrine_Rawsql for the above SQL query?
if incase if someone wants to check the tables here is the link to fiddle http://sqlfiddle.com/#!2/5adaa
UPDATE: this is continuation of this question, select query and count based on condition if someone could help me build Doctrine_Rawsql by using any of the query from the solution provided by #MvG

I have problem that I hope someone can help me with.
SELECT a.country_name, s.state_name, c.city_id,
LEAST (c.next_1, c.next_2, c.next_3) AS next_visit,
MAX(v.visit_time) AS last_visit
FROM city c
INNER JOIN country a ON a.id = c.country
INNER JOIN state s ON s.id = c.state
INNER JOIN visit_log v ON CONCAT(c.country, c.state, c.city_id) = CONCAT(v.country, v.state, v.city_id)
GROUP BY CONCAT(v.country, v.state, v.city_id)
ORDER BY a.id ASC, s.id ASC, c.city_id
My main problem now is that I can't get the col_1 and col_2 from the visit_log corresponding with MAX(visit_log)
SQLfiddle
You can add the "latest" requirement to the join condition:
SELECT *
FROM city c
JOIN country a
ON a.id = c.country
JOIN state s
ON s.id = c.state
JOIN visit_log v
ON v.country = c.country
AND v.state = c.state
AND v.city_id = c.city_id
AND visit_time =
(
SELECT MAX(visit_time)
FROM visit_log v2
WHERE v2.country = c.country
AND v2.state = c.state
AND v2.city_id = c.city_id
)
You can find many other approaches in the greatest-n-per-group+mysql tag. For optimal speed you'd use an approach using variables.
You can try this:-
SELECT C.NAME, S.NAME, CN.ID, NV.Next_visit_1, VL.visited
FROM COUNTRY C INNER JOIN next_visit NV ON C.ID = NV.Country
INNER JOIN STATE S ON NV.State = S.ID
JOIN CITY
INNER JOIN visitor_log VL ON CONCAT(NV.country, NV.state, NV.city) = CONCAT(VL.country, VL.state, VL.city)
I have an mysql query for getting which user assigned to which course and if the course having certificate then only the results will be prints. for this i am using inner join with many table. Here is the code :
SELECT DISTINCT c.fullname,usr.id, usr.username, usr.email, c.enrolenddate
FROM m_tl_course AS c
INNER JOIN m_tl_context AS cx ON c.id = cx.instanceid AND cx.contextlevel = '50'
INNER JOIN m_tl_role_assignments AS ra ON cx.id = ra.contextid
INNER JOIN m_tl_role AS r ON ra.roleid = r.id
INNER JOIN m_tl_user AS usr ON ra.userid = usr.id
INNER JOIN m_tl_certificate AS ce ON ce.course = c.id
WHERE r.name = "Student" and ra.timeend = '0'
I have an another table to having data's like the user's who's download their certificate. The table name is m_tl_certification.
In this table having Columns like, user_id ( this the user id), Course_id (this is the course id), cert_date ( this is the certificate download date).
What i want is i want to get the user's who is not download their certicate.
How to get this. please can anyone help me ?
What will be the column value if not downloaded and if downloaded. If the Download date is NULL then in where add Download_Date IS NULL
SELECT DISTINCT c.fullname,usr.id, usr.username, usr.email,c.enrolenddate
FROM m_tl_course AS c
INNER JOIN m_tl_context AS cx ON c.id = cx.instanceid AND cx.contextlevel = '50'
INNER JOIN m_tl_role_assignments AS ra ON cx.id = ra.contextid
INNER JOIN m_tl_role AS r ON ra.roleid = r.id
INNER JOIN m_tl_user AS usr ON ra.userid = usr.id
INNER JOIN m_tl_certificate AS ce ON ce.course = c.id INNER JOIN m_tl_certificate AS ce ON ce.course = c.id
INNER JOIN m_tl_certification As cee ON cee.user_id = usr.id
WHERE r.name = "Student" and ra.timeend = '0' and cee.downloadDate IS NULL
Modify your query with the following
SELECT DISTINCT c.fullname,usr.id, usr.username, usr.email, c.enrolenddate
FROM m_tl_course AS c
INNER JOIN m_tl_context AS cx ON c.id = cx.instanceid AND cx.contextlevel = '50'
INNER JOIN m_tl_role_assignments AS ra ON cx.id = ra.contextid
INNER JOIN m_tl_role AS r ON ra.roleid = r.id
INNER JOIN m_tl_user AS usr ON ra.userid = usr.id
LEFT JOIN m_tl_certificate AS ce ON ce.course = c.id
WHERE r.name = "Student" and ra.timeend = '0'
I want to select all categories, subcategories and count the number of business that belongs to subcategory. this is the SQl query i am using.
SELECT
c.id,
c.name,
c.slug,
sc.id,
sc.name,
sc.slug,
COUNT(bsc.id) AS business_count
FROM
fi_category c
LEFT JOIN
fi_subcategory sc ON c.id = sc.category_id AND (sc.deleted_at IS NULL)
LEFT JOIN
fi_business_subcategory bsc ON sc.id = bsc.subcategory_id AND (bsc.deleted_at IS NULL)
WHERE
(c.deleted_at IS NULL)
GROUP BY
c.id, sc.id
however there is more i want to do, business_count should be filtered according to the city they belong i.e in the end i want to select all category, subcategory but business_count should have a clause like WHERE city.id = 1, for this i guess i have to use count as subquery which i am not been able to figure out.
below is the relationship structure from fi_business_subcategory to fi_city.
1) fi_business_subcategory
+----+----------------+-------------+
| id | subcategory_id | business_id |
+----+----------------+-------------+
2) fi_business
+----+---------+-----------+
| id | name | suburb_id |
+----+---------+-----------+
3) fi_suburb
+-----+--------+---------+
| id | name | city_id |
+-----+--------+---------+
4) fi_city
+----+--------+
| id | name |
+----+--------+
i tried something like this, but this doesn't seem to work
SELECT
c.id,
c.name,
c.slug,
sc.id,
sc.name,
sc.slug,
bsc.business_count
FROM
fi_category c
LEFT JOIN
fi_subcategory sc ON c.id = sc.category_id AND (sc.deleted_at IS NULL)
LEFT JOIN (
SELECT
COUNT(business_id) t1.business_count, t1.subcategory_id
FROM
fi_business_subcategory t1
LEFT JOIN
fi_business t2 ON t2.id = t1.business_id
LEFT JOIN
fi_suburb t3 ON t3.id = t2.suburb_id
LEFT JOIN
fi_city t4 ON t4.id = t3.city_id
WHERE
t4.id = 1
GROUP BY
t1.subcategory_id
) bsc ON sc.id = bsc.subcategory_id AND (bsc.deleted_at IS NULL)
WHERE
(c.deleted_at IS NULL)
GROUP BY
c.id, sc.id
how should i build up the query to achieve what i want?
I see no reason why you should have to use a subquery. I believe that you can simply combine fi_business and fi_business_subcategory to a single parenthesized table factor.
SELECT
c.id,
c.name,
c.slug,
sc.id,
sc.name,
sc.slug,
COUNT(bsc.id) AS business_count
FROM
fi_category c
LEFT JOIN
fi_subcategory sc ON c.id = sc.category_id AND (sc.deleted_at IS NULL)
LEFT JOIN (
fi_business b
INNER JOIN
fi_business_subcategory bsc ON b.id = bsc.business_id AND (bsc.deleted_at IS NULL)
INNER JOIN
fi_suburb su ON su.id = b.suburb_id AND su.city_id = 1
) ON sc.id = bsc.subcategory_id
WHERE
(c.deleted_at IS NULL)
GROUP BY
c.id, sc.id
I've checked that this is valid SQL for your table structure. I guess chances are good that it will yield the desired result, even though your fiddle doesn't contain any data yet. See the manual on JOIN syntax for details on where you can use parentheses in a join.
You might also ask yourself if you really need all the joins to be left joins. Writing things using inner joins would be much easier.
As joins are executed left to right, you might do the inner joins first, followed by a sequence of right joins. This avoids the parentheses:
SELECT
c.id cat_id,
c.name cat_name,
c.slug cat_slug,
sc.id sub_id,
sc.name sub_name,
sc.slug sub_slug,
COUNT(bsc.id) AS business_count
FROM
fi_business b
INNER JOIN
fi_business_subcategory bsc ON b.id = bsc.business_id
AND (b.deleted_at IS NULL) AND (bsc.deleted_at IS NULL)
INNER JOIN
fi_suburb su ON su.id = b.suburb_id AND su.city_id = 1
RIGHT JOIN
fi_subcategory sc ON sc.id = bsc.subcategory_id
RIGHT JOIN
fi_category c ON c.id = sc.category_id AND (sc.deleted_at IS NULL)
WHERE
(c.deleted_at IS NULL)
GROUP BY
c.id, sc.id
If you want to use a subquery, a correct way to phrase your second query with as litle change as possible would be this:
SELECT
c.id,
c.name,
c.slug,
sc.id,
sc.name,
sc.slug,
IFNULL(bsc.business_count, 0)
-- turn NULL from left join into 0
FROM
fi_category c
LEFT JOIN
fi_subcategory sc ON c.id = sc.category_id AND (sc.deleted_at IS NULL)
LEFT JOIN (
SELECT
COUNT(*) business_count, t1.subcategory_id
-- removed table name from alias name,
-- and improved performance by simply counting rows
FROM
fi_business_subcategory t1
LEFT JOIN
fi_business t2 ON t2.id = t1.business_id
LEFT JOIN
fi_suburb t3 ON t3.id = t2.suburb_id
LEFT JOIN
fi_city t4 ON t4.id = t3.city_id
WHERE
t4.id = 1 AND (t1.deleted_at IS NULL)
-- check deletion in subquery for performance
GROUP BY
t1.subcategory_id
) bsc ON sc.id = bsc.subcategory_id
-- no longer need to check deletion here
WHERE
(c.deleted_at IS NULL)
GROUP BY
c.id, sc.id
Fiddle here.
Try this
select
c.id,
c.name,
count(sc.name) as Count
from fi_category as c
left join fi_subcategory as sc on sc.category_id = c.id
left join fi_business_subcategory as fbs on fbs.subcategory_id = sc.id
inner join (
select
fb.name,
fs.id,
fs.city_id
from fi_business as fb
inner join fi_suburb as fs on fs.id = fb.suburb_id
where fs.city_id = 1
) as fb on fb.id = fbs.business_id
group by c.id
SELECT u.username,
r.position,
r.score,
r.winner,
t.team
FROM ".TBL_FOOT_TOUR_ROUNDS." r
LEFT JOIN ".TBL_USERS." u
ON u.id = r.winner
LEFT JOIN ".TBL_FOOT_TOUR_PLAYERS." pl
ON pl.userid = r.winner
LEFT JOIN ".TBL_FOOT_TEAMS." t
ON t.id = pl.team
WHERE pl.tourid = '$tour_id' && r.tourid = '$tour_id' && r.round = '$i'
ORDER BY r.position
I have one problem with this query. The WHERE pl.tourid = '$tour_id' is reliant on the LEFT JOIN ".TBL_FOOT_TOUR_PLAYERS." pl ON pl.userid = r.winner. As it's a left join, how can I make that WHERE only function if the LEFT JOIN does?
Can't think of a solution!
Thanks
I guess that you only want rows with no matching winner, or where the winner has the specified tourid. In this case, you would use:
WHERE (pl.tourid IS NULL OR pl.tourid = '$tour_id')
Alternatively, if you only want to link to the player if (s)he has the right tourid, then add it to the ON clause:
ON pl.userid = r.winner AND pl.tourid = '$tour_id'
The results will be different, either might be what you are looking for.
SELECT u.username,
r.position,
r.score,
r.winner,
t.team
FROM ".TBL_FOOT_TOUR_ROUNDS." r
LEFT JOIN ".TBL_USERS." u
ON u.id = r.winner
LEFT JOIN ".TBL_FOOT_TOUR_PLAYERS." pl
ON pl.userid = r.winner
AND pl.tourid = '$tour_id'
AND r.tourid = '$tour_id'
AND r.round = '$i'
LEFT JOIN ".TBL_FOOT_TEAMS." t
ON t.id = pl.team
ORDER BY r.position

This only returns records from the summary table that has a relating record in the uploads table (s.id = uploads.summary_id) that contain a value within the uploads.summary_id field
I want to return all records, whether or not it has a file associated with it.
Any help is appreciated.
Suggest refactoring this SQL query to use ANSI joins. To achive your goal, you'd want a LEFT JOIN instead:
SELECT /*your columns*/
from summary s
INNER JOIN year y1 ON s.current_year_id = y1.id
INNER JOIN year y2 ON s.previous_year_id = y2.id
INNER JOIN strategic_goal_entries sge ON s.id = sge.summary_id
INNER JOIN goal g ON sge.goal_id = g.id
INNER JOIN department d ON s.department_id = d.id
LEFT JOIN uploads u ON s.id = u.summary_id
WHERE s.department_id = '4'
group by s.id
