Dissolve second select statement - mysql

I got following query which is as well working.
SELECT date, duration, educationDepartment, yearOfTraining, completedtasks
FROM programm_completedtask
WHERE date BETWEEN '2014-08-05' AND '2014-08-08'
AND trainee_id =
(SELECT id FROM programm_trainee WHERE username = 'Markus');
Is it possible to do anything else instead of the second select statement ? I would love to just select once.

Use an INNER JOIN ...
SELECT p.date, p.duration, p.educationDepartment, p.yearOfTraining, p.completedtasks
FROM programm_completedtask as p
INNER JOIN programm_trainee as pt on p.trainee_id = pt.id AND pt.username = 'Markus'
WHERE p.date BETWEEN '2014-08-05' AND '2014-08-08'
or
SELECT p.date, p.duration, p.educationDepartment, p.yearOfTraining, p.completedtasks
FROM programm_completedtask as p
INNER JOIN programm_trainee as pt on p.trainee_id = pt.id
WHERE p.date BETWEEN '2014-08-05' AND '2014-08-08'
AND pt.username = 'Markus'

References Outer Query MySQL

i tried use "Total" in outer where, and i got error "Unknown "AL.Total", how to fix it ?
here my query :
SELECT

AL.NAME,
SUM(AL.BEGINING+AL.MUTATION) AS TOTAL
from
(SELECT

Try HAVING TOTAL >0 instead of WHERE AL.TOTAL >0,because TOTAL
is not in AL temp table

How to order a SQL statemnet according to alias name

I have the next SQL statement:
SELECT
p.ID,
p.TheName0,
(SELECT IFNULL(SUM(att.S_FinalAmount),0) From tbl_groups_classes_att att
INNER JOIN tbl_students st
ON st.ID = att.StudentID
INNER JOIN tbl_groups_classes cls
ON cls.ID = att.ClassID
WHERE st.ParentID = p.ID
and cls.TheDate BETWEEN #Date1 and #Date2
and att.TheStatus <> 'absent'
) as CurrMost,
(SELECT IFNULL(SUM(att.S_FinalAmount),0) From tbl_groups_classes_att att
INNER JOIN tbl_students st
ON st.ID = att.StudentID
INNER JOIN tbl_groups_classes cls
ON cls.ID = att.ClassID
WHERE st.ParentID = p.ID and cls.TheDate< #Date1 and att.TheStatus <> 'absent'
) as PrevMost,
(SELECT IFNULL(SUM(pay.TheAmount),0) From tbl_parents_payments pay Where p.ID = pay.ParentID
AND pay.TheDate BETWEEN #Date1 and #Date2
) as CurrMadf,
(SELECT IFNULL(SUM(pay.TheAmount),0) From tbl_parents_payments pay Where p.ID = pay.ParentID
AND pay.TheDate < #Date1
) as PrevMadf,
(SELECT CurrMost + PrevMost) as AllMost,
(SELECT CurrMadf + PrevMadf) as AllMadf,
(SELECT AllMost - AllMadf) AS FinalTotal
from tbl_parents p
I want to order it by FinalTotal, I tried to put :
from tbl_parents p order by FinalTotal
but it doesn't be affected.
how I can sort it? and please note that I tried many solutions on the internet but without result.
thanks advanced
The fail-safe solution is to place the whole query as a table expression to produce the column name, and then sorting is trivial.
For example:
select *
from (
-- your query here
) x
order by FinalTotal

Getting the latest date from a id

I run the above sql statement and i got this.[IMG]http://i1093.photobucket.com/albums/i422/walkgirl_1993/asd-1_zps5506632e.jpg[/IMG] i'm trying display the latest date which you can see the 3 and 4. For caseid 3, it should display the latest row which is the 2012-12-20 16:12:36.000. I tried using group by, order by. Google some website said to use rank but i'm not sure about the rank as i dont really get rank. Some suggestions?
select [Case].CaseID, Agent.AgentName, Assignment.Description, A.AgentName as EditedBy, A.DateEdited from Agent inner join [Case-Agent] on [Case-Agent].AgentID = Agent.AgentID inner join [Assignment] on Assignment.AssignmentID = [Case-Agent].AssignmentID inner join [Case] on [Case].CaseID = [Case-Agent].CaseID inner join (select EditedCase.CaseID, [EditedCase].DateEdited, [Agent].AgentName from EditedCase inner join [Agent] on [Agent].AgentID = [EditedCase].AgentID) A on A.CaseID = [Case].CaseID where [Assignment].AssignmentID = 0
To do it using RANK you just need to add the RANK to the subquery and get to rank the DateEdited for each CaseID and Agent and then in the main query put a WHERE clause to only select rows where the rank is 1. I think I have got the partition clause right - its a bit hard without seeing your data.
Like this:
SELECT
[Case].CaseID
,Agent.AgentName
,Assignment.Description
,A.AgentName AS EditedBy
,A.DateEdited
FROM Agent
INNER JOIN [Case-Agent] ON [Case-Agent].AgentID = Agent.AgentID
INNER JOIN [Assignment] ON Assignment.AssignmentID = [Case-Agent].AssignmentID
INNER JOIN [Case] ON [Case].CaseID = [Case-Agent].CaseID
INNER JOIN (SELECT
EditedCase.CaseID
,[EditedCase].DateEdited
,[Agent].AgentName
,RANK ( ) OVER (PARTITION BY EditedCase.CaseID, [Agent].AgentName
ORDER BY [EditedCase].DateEdited DESC ) AS pos
FROM EditedCase
INNER JOIN [Agent] on [Agent].AgentID = [EditedCase].AgentID) A on A.CaseID = [Case].CaseID
WHERE [Assignment].AssignmentID = 0
AND pos = 1
You could also change the sub query into an aggregate query that brings back the MAX date like this:
SELECT
[Case].CaseID
,Agent.AgentName
,Assignment.Description
,A.AgentName AS EditedBy
,A.DateEdited
FROM Agent
INNER JOIN [Case-Agent] ON [Case-Agent].AgentID = Agent.AgentID
INNER JOIN [Assignment] ON Assignment.AssignmentID = [Case-Agent].AssignmentID
INNER JOIN [Case] ON [Case].CaseID = [Case-Agent].CaseID
INNER JOIN (SELECT
EditedCase.CaseID
,MAX([EditedCase].DateEdited) AS DateEdited
,[Agent].AgentName
FROM EditedCase
INNER JOIN [Agent] on [Agent].AgentID = [EditedCase].AgentID
GROUP BY
EditedCase.CaseID
,[Agent].AgentName) A on A.CaseID = [Case].CaseID
WHERE [Assignment].AssignmentID = 0
AND pos = 1
You were on the right track; you need to use a ranking function here, for example row_number():
with LatestCase as
(
select [Case].CaseID
, Agent.AgentName
, Assignment.Description
, A.AgentName as EditedBy
, A.DateEdited
, caseRank = row_number() over (partition by [Case].CaseID order by A.DateEdited desc)
from Agent
inner join [Case-Agent] on [Case-Agent].AgentID = Agent.AgentID
inner join [Assignment] on Assignment.AssignmentID = [Case-Agent].AssignmentID
inner join [Case] on [Case].CaseID = [Case-Agent].CaseID
inner join
(
select EditedCase.CaseID
, [EditedCase].DateEdited
, [Agent].AgentName
from EditedCase
inner join [Agent] on [Agent].AgentID = [EditedCase].AgentID
) A on A.CaseID = [Case].CaseID where [Assignment].AssignmentID = 0
)
select *
from LatestCase
where caseRank = 1

Using JOIN sql query

I would like to use JOIN instead of IN in the following SQL query. I can't figure out how to do it.
SELECT * FROM shop_orders WHERE
id IN (SELECT orders_id FROM shop_orders_data WHERE closed='1' /*AND backorder='0'*/ AND exhibition_id='389' AND
exhibition_id IN (SELECT id FROM shop_exhibitions WHERE
country_id IN (SELECT id FROM countries WHERE id='72')) AND in_country = '72' AND
exhibition_id IN (SELECT id FROM shop_exhibitions WHERE start<=1336946400 AND end>1336600800)) AND
id IN (SELECT orders_id FROM shop_orders_products WHERE
products_id IN (SELECT id FROM shop_products WHERE artno='120000' OR name LIKE '%120000%')) AND created>=1333231200 AND created<1333663200 ORDER BY created DESC
I tried this:
SELECT
s.*
FROM
shop_orders s
INNER JOIN shop_orders_data od ON s.id=od.orders_id
INNER JOIN shop_exhibitions se ON od.exhibition_id=se.id
INNER JOIN countries co ON se.country_id=co.id
INNER JOIN shop_orders_products sop ON s.id=sop.orders_id
INNER JOIN shop_products sp
ON sop.products_id=sp.id
WHERE od.closed=1
AND ( sp.artno='120000' or sp.name LIKE '%120000%' )
AND ( od.exhibition_id='389')
AND ( od.in_country = '72')
AND ( se.start <=1336946400)
AND ( se.end >1336600800)
AND ( se.created>=1333231200)
AND ( se.created<1333663200)
ORDER BY `s`.`created` DESC
I this correct??
See if this works (and study the code to learn how it works):
SELECT *
FROM shop_orders so
JOIN shop_orders_data sod ON (
(so.id = sod.orders_id)
AND (sod.closed = '1')
/*AND (sod.backorder = '0') */
AND (sod.exhibition_id = '389')
AND (sod.in_country = '72')
)
JOIN shop_exhibitions se ON (
(sod.exhibition_id = se.id)
AND (se.start <= 1336946400)
AND (se.end > 1336600800)
)
JOIN countries c ON (
(se.country_id = c.id)
AND (c.id = '72')
)
JOIN shop_orders_products sop ON (
(so.id = sop.orders_id)
)
JOIN shop_products sp ON (
(sop.products_id = sp.id)
AND ((sp.artno='120000') OR (sp.name LIKE '%120000%'))
)
WHERE (so.created >= 1333231200) AND (so.created < 1333663200)
ORDER BY so.created DESC;
The join syntax works like this:
SELECT field1,field2,field3
FROM FirstTable
JOIN SecondTable ON (FirstTable.PrimaryKey = SecondTable.ForeignKey)
JOIN ThirdTable ON (FirstTable.PrimaryKey = ThirdTable.ForeignKey)
Try applying this approach to your query.

SQL Query Problem

I've been at this for a bit now. Basically, I'm needing to add a derived column to count the hits to a weblog entry in the database. The problem is, the hits are being totaled and shown on only on the first record. Any Ideas? I've emboldened the parts of the query I'm talking about. The query is below:
SELECT DISTINCT(t.entry_id),
exp_categories.rank,
**exp_hits.hits,**
t.entry_id,
t.weblog_id,
t.forum_topic_id,
t.author_id,
t.ip_address,
t.title,
t.url_title,
t.status,
t.dst_enabled,
t.view_count_one,
t.view_count_two,
t.view_count_three,
t.view_count_four,
t.allow_comments,
t.comment_expiration_date,
t.allow_trackbacks,
t.sticky,
t.entry_date,
t.year,
t.month,
t.day,
t.entry_date,
t.edit_date,
t.expiration_date,
t.recent_comment_date,
t.comment_total,
t.trackback_total,
t.sent_trackbacks,
t.recent_trackback_date,
t.site_id as entry_site_id,
w.blog_title,
w.blog_name,
w.search_results_url,
w.search_excerpt,
w.blog_url,
w.comment_url,
w.tb_return_url,
w.comment_moderate,
w.weblog_html_formatting,
w.weblog_allow_img_urls,
w.weblog_auto_link_urls,
w.enable_trackbacks,
w.trackback_use_url_title,
w.trackback_field,
w.trackback_use_captcha,
w.trackback_system_enabled,

m.bio,
md.*,

FROM exp_weblog_titles AS t
LEFT JOIN exp_weblogs AS w ON t.weblog_id = w.weblog_id
LEFT JOIN exp_weblog_data AS wd ON t.entry_id = wd.entry_id
LEFT JOIN exp_members AS m ON m.member_id = t.author_id
LEFT JOIN exp_member_data AS md ON md.member_id = m.member_id
LEFT JOIN exp_category_posts ON wd.entry_id = exp_category_posts.entry_id
**LEFT JOIN
(
SELECT COUNT(*) AS hits, exp_hits.entry_id FROM exp_hits ORDER BY exp_hits.entry_id
) exp_hits ON t.entry_id = exp_hits.entry_id**
LEFT JOIN
(
SELECT exp_categories.cat_id, cat_name as rank
FROM exp_categories
WHERE exp_categories.group_id = '9'
) exp_categories ON exp_categories.cat_id = exp_category_posts.cat_id
WHERE t.entry_id IN (2,3,4) ORDER BY exp_categories.rank DESC, **exp_hits.hits DESC**, entry_date desc
Try changeing the subselect to
SELECT COUNT(*) AS hits,
exp_hits.entry_id
FROM exp_hits
GROUP BY exp_hits.entry_id
Out of curiosity, is your hits functionality something that can't be accomplished with the view_count_one/two/three/four fields already present in the database and supported by ExpressionEngine template tags?
