this query is works for activity
$query1 = "select t.entity_id, t.parent_id, t.length,gu.measurement_unit_id
from tree t
left join units u
on t.parent_id = u.region_id
and u.activity_id IN (some activity_id)
left join product_grid_units gu
on u.id = gu.unit_id
WHERE t.entity_id IN (some region_id)";
and this query works for region
$query2 = "select t.entity_id, t.parent_id, t.length,gu.measurement_unit_id
from tree t
left join units u
on t.parent_id = u.activity_id
and u.region_id IN (some region_ids)
left join product_grid_units gu
on u.id = gu.unit_id
WHERE t.entity_id IN ("some activity_ids")";
so i want to combine this two querys...can anyone help?...
Use UNION(implicit distinct) or UNION ALL like this:
select t.entity_id, t.parent_id, t.length,gu.measurement_unit_id
from tree t
left join units u on t.parent_id = u.region_id
and u.activity_id IN (some activity_id)
left join product_grid_units gu on u.id = gu.unit_id
WHERE t.entity_id IN (some region_id)
UNION ALL
select t.entity_id, t.parent_id, t.length,gu.measurement_unit_id
from tree t
left join units u on t.parent_id = u.activity_id
and u.region_id IN (some region_ids)
left join product_grid_units gu on u.id = gu.unit_id
WHERE t.entity_id IN ("some activity_ids")

I'm writing a query with multiple joins where I want every user to show entries against all category Types. When I execute the query below only 1 record is returned because the employee u.employee_id = "0079-P" has only worked on 1 project but I want to get data for all the category_types with users workhours displayed as null for the categories he didn't work on.
Select u.employee_id As Employee_ID, u.user_name As UserName, COALESCE(primaryDept.ctd_name, primaryProj.ctd_name) As PrimaryDeptOrProj, region.region_name As Region, categoryType.ctd_id, categoryType.ctd_name, SUM(tsdd.workhours)
From users u
LEFT JOIN category_type_details primaryDept ON u.user_primary_department = primaryDept.ctd_id
LEFT JOIN category_type_details primaryProj ON u.user_primary_project = primaryProj.ctd_id
LEFT JOIN regions region ON u.region_id = region.region_id
LEFT JOIN timesheets ts ON u.user_id = ts.timesheet_user
INNER JOIN timesheet_mr tsmr ON ts.timesheet_caller = tsmr.tsmr_id
INNER JOIN timesheet_details tsd ON ts.timesheet_id = tsd.tsd_timesheet_id
INNER JOIN timesheet_day_details tsdd ON tsd.tsd_id = tsdd.tsd_id
RIGHT OUTER JOIN category_type_details categoryType ON tsd.tsd_category_type_id = categoryType.ctd_id
WHERE tsmr.tsmr_id = 14 and u.employee_id = "0079-P"
GROUP BY u.user_id, tsd.tsd_category_type_id;
I tried this query with variations and it returns 1 record in any case.
You could change your query to this:
SELECT u.employee_id AS Employee_ID, u.user_name AS UserName,
COALESCE(pd.ctd_name, pp.ctd_name) AS PrimaryDeptOrProj,
r.region_name AS Region, ct.ctd_id, ct.ctd_name, SUM(tsdd.workhours)
FROM users u
LEFT JOIN category_type_details pd ON u.user_primary_department = pd.ctd_id
LEFT JOIN category_type_details pp ON u.user_primary_project = pp.ctd_id
LEFT JOIN regions r ON u.region_id = r.region_id
LEFT JOIN timesheets ts ON u.user_id = ts.timesheet_user
INNER JOIN timesheet_mr tsmr ON ts.timesheet_caller = tsmr.tsmr_id AND tsmr.tsmr_id = 14
INNER JOIN timesheet_details tsd ON ts.timesheet_id = tsd.tsd_timesheet_id
INNER JOIN timesheet_day_details tsdd ON tsd.tsd_id = tsdd.tsd_id
RIGHT OUTER JOIN category_type_details ct ON tsd.tsd_category_type_id = ct.ctd_id AND u.employee_id = "0079-P"
GROUP BY ct.ctd_id, u.user_id, u.employee_id, u.user_name,
COALESCE(pd.ctd_name, pp.ctd_name), r.region_name, ct.ctd_name
ORDER BY ct.ctd_id, u.user_id, u.employee_id, u.user_name,
COALESCE(pd.ctd_name, pp.ctd_name), r.region_name, ct.ctd_name;
You only got 1 row because the condition in WHERE clause filter all the NULL user_id rows for other category.
For MySQL, you could omit other columns in GROUP BY clause:
SELECT u.employee_id AS Employee_ID, u.user_name AS UserName,
COALESCE(pd.ctd_name, pp.ctd_name) AS PrimaryDeptOrProj,
r.region_name AS Region, ct.ctd_id, ct.ctd_name, SUM(tsdd.workhours)
FROM users u
LEFT JOIN category_type_details pd ON u.user_primary_department = pd.ctd_id
LEFT JOIN category_type_details pp ON u.user_primary_project = pp.ctd_id
LEFT JOIN regions r ON u.region_id = r.region_id
LEFT JOIN timesheets ts ON u.user_id = ts.timesheet_user
INNER JOIN timesheet_mr tsmr ON ts.timesheet_caller = tsmr.tsmr_id AND tsmr.tsmr_id = 14
INNER JOIN timesheet_details tsd ON ts.timesheet_id = tsd.tsd_timesheet_id
INNER JOIN timesheet_day_details tsdd ON tsd.tsd_id = tsdd.tsd_id
RIGHT OUTER JOIN category_type_details ct ON tsd.tsd_category_type_id = ct.ctd_id AND u.employee_id = "0079-P"
GROUP BY ct.ctd_id, u.user_id
ORDER BY ct.ctd_id, u.user_id;
I want to convert this query in such a way so it does not have any 'exists' and uses only simple joins.
select t.Teacher_id, t.Teacher_name, a.marks, a.grade_ID
from Grades a
left join students s on a.student_ID = s.student_ID
left join Teachers t on t.Teacher_ID = s.Teacher_ID
where 1=1 and t.Teacher_id = 1807600
and exists(
select p.Payment_ID from payments p
inner join lookups l on (l.lookup_id = p.status_id and l.lookup_key in ('condition1','condition2'))
where p.student_ID = a.student_ID
)
I tried something like:
select t.Teacher_id, t.Teacher_name, a.marks, a.grade_ID
from Grades a
left join students s on a.student_ID = s.student_ID
left join Teachers t on t.Teacher_ID = s.Teacher_ID
inner join payments p on p.student_ID = a.student_ID
inner join lookups l on (l.lookup_id = p.status_id and l.lookup_key in ('condition1','condition2'))
where 1=1 and t.Teacher_id = 1807600
But I'm not getting the right results. Can you please help. Thanks.
I suppose you could use group by, but this restricts the maintainability of the script for the simple sake of not using EXISTS().
select t.Teacher_id, t.Teacher_name, a.marks, a.grade_ID
from Grades a
left join students s on a.student_ID = s.student_ID
left join Teachers t on t.Teacher_ID = s.Teacher_ID
inner join payments p on p.student_ID = a.student_ID
inner join lookups l on (l.lookup_id = p.status_id and l.lookup_key in ('condition1','condition2'))
where t.Teacher_id = 1807600
group by t.Teacher_id, t.Teacher_name, a.marks, a.grade_ID
We have a home grown document management system and our system is running very slow, particularly on the search. It worked fine at first, but it has gotten progressively slower over time. Its now taking anywhere from 30 to 150 seconds to return results depending upon criteria. This is our search query. We’ve been staring at this thing left and right and can’t see any place to tune this more. All of the joined fields are indexed on their respective tables.

This might be an obvious answer, but have you indexed your database? If you're new to indexing, here's a pretty good rule: just put a unique index on all the columns named "id", such as folders.id or projects.id, then put a standard index on all the columns that reference a foreign id, such as folder.belongs_to_folder_id or folder.record_type_id
Another thing I would change is to try and select only the columns you will actually use rather than your huge list of f.*, ts.*, fo.*, ft.*, p.*, u.*, c.*, co.*, ct.*, fs.*, etc...
You also have TONS of joins, which are very expensive in terms of processing time. Do you really need all those joined tables?
SELECT s.*,
u.username,
u.fullname,

COUNT(DISTINCT v.id) AS views

INNER JOIN users u ON u.id = s.user_id
INNER JOIN categories c ON c.id = s.cat_id
LEFT OUTER JOIN(

LEFT OUTER JOIN views v ON v.shot_id = s.id
**WHERE s.library = 1 AND sa.attention > 40
ORDER BY sa.attention DESC
LIMIT 0,50**
GROUP BY s.id
I can't use the sa.attention in a condition and for ordering. Why?
(I removed the marked part, and the query works!)
What do I have to change in my Query? And if you could give a explanation for it, that would be very nice!
You are negating your OUTER JOIN by putting that in your WHERE criteria. Move it to your JOIN and you'll get your NULL records back:
SELECT s.*,
u.username,
u.fullname,
c.title AS ctitle,
c.description AS cdescription,
sa.attention,
sp.popularity,
COUNT(DISTINCT f.id) AS favorites,
COUNT(DISTINCT st.id) AS stars,
COUNT(DISTINCT v.id) AS views
FROM shots s
INNER JOIN users u ON u.id = s.user_id
INNER JOIN categories c ON c.id = s.cat_id
LEFT OUTER JOIN(
SELECT shot_id, round(AVG(count),2) AS attention
FROM points
WHERE date > DATE_SUB(CURDATE(),INTERVAL 2 DAY)
GROUP BY shot_id
) sa ON sa.shot_id = s.id AND sa.attention > 40
LEFT OUTER JOIN(
SELECT shot_id, SUM(count) AS popularity
FROM points
GROUP BY shot_id
) sp ON sp.shot_id = s.id
LEFT OUTER JOIN favorites f ON f.shot_id = s.id
LEFT OUTER JOIN stars st ON st.shot_id = s.id
LEFT OUTER JOIN views v ON v.shot_id = s.id
WHERE s.library = 1
GROUP BY s.id
ORDER BY sa.attention DESC
LIMIT 0,50
A second note, GROUP BY cannot go at the end. I moved that to the correct spot as well.
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
