When I add SUM around my case select, it returns the summed value without the GROUP BY.
The query I am using, without the SUM, is the following
SELECT CASE WHEN subscription_types.type = 'Succes lidmaatschap' THEN 7 ELSE 8 END FROM subscription_used
INNER JOIN training_sessions ON training_sessions.id = subscription_used.training_session_id
INNER JOIN training_series AS tserie ON tserie.id = training_sessions.training_serie_id
INNER JOIN user_training_session ON user_training_session.training_session_id = training_sessions.id
INNER JOIN subscriptions ON subscriptions.id = subscription_used.subscription_id
INNER JOIN subscription_types ON subscription_types.id = subscriptions.subscription_type_id
WHERE subscription_used.training_session_id = (SELECT training_sessions.id FROM training_sessions WHERE DATE(event_start_date) = #week_2_ago_date AND training_serie_id = 17) AND present=1
GROUP BY subscriptions.id
This query returns the values: 8,7. However, when I put a SUM around the case, it gives me the number 75. 75 is the SUM of the values that are getting returned without the GROUP BY.
Any ideas on how to fix this problem so that the query gives me the correct value (8+7 = 15, 1 row)? Thanks in advance
Group by is implying distinct values based on subscription.id so probably if you take the group by you you will get something like 8,8,8,8,8,7,7,7,7,7 due to the joins and such.
With the group by you only get the distinct values of 8 and 7. When you do sum with the group it will sum all of them though not the 2 distinct.
Most Simple fix that will give you 15:
SELECT SUM(SUBSCRIPTION_USED) FROM (
SELECT CASE WHEN subscription_types.type = 'Succes lidmaatschap' THEN 7 ELSE 8 END FROM subscription_used
INNER JOIN training_sessions ON training_sessions.id = subscription_used.training_session_id
INNER JOIN training_series AS tserie ON tserie.id = training_sessions.training_serie_id
INNER JOIN user_training_session ON user_training_session.training_session_id = training_sessions.id
INNER JOIN subscriptions ON subscriptions.id = subscription_used.subscription_id
INNER JOIN subscription_types ON subscription_types.id = subscriptions.subscription_type_id
WHERE subscription_used.training_session_id = (SELECT training_sessions.id FROM training_sessions WHERE DATE(event_start_date) = #week_2_ago_date AND training_serie_id = 17) AND present=1
GROUP BY subscriptions.id);
Probably a better way to write it in general though.
EDIT: You could also do SUM(DISTINCT CASE......) if you only want to sum distinct values.

I have a query in which I compare a rounded sum to an integer, and I'm receiving unexpected results.
SELECT assignments.*
FROM assignments
INNER JOIN time_entries
ON time_entries.assignment_id = assignments.id
WHERE assignments.organization_id = 2
AND assignments.allocation_mode = 'fixed'
AND (fixed_hours is not null)
HAVING round(sum(time_entries.scheduled_hours)) != round(assignments.fixed_hours);
It returns an assignment with fixed_hours of 20. The column is a float.
When I select the sum of the time_entries for that match that record, I get 20.000000298023224. When I call round on that, I get 20:
SELECT
round(sum(scheduled_hours))
FROM time_entries
WHERE assignment_id=112869;
And SELECT round(fixed_hours) from assignments where id=112869 also gives 20.
And of course select round(20.000000298023224) = round(20); returns 1.
So what's wrong with my query that that record is being returned?
Nice try at query summarization :), but you need a group by...
SELECT
assignments.*
FROM assignments
INNER JOIN (
SELECT
assignment_id
, ROUND(SUM(time_entries.scheduled_hours)) sum_hrs
FROM time_entries
GROUP BY
assignment_id
) te ON assignments.id = te.assignment_id
WHERE assignments.organization_id = 2
AND assignments.allocation_mode = 'fixed'
AND (fixed_hours IS NOT NULL)
AND te.sum_hrs <> ROUND(assignments.fixed_hours)
;
I've found a few posts in here that are similar, but doesn't work with what i'd like to do...
similar post: Trying to write a query that counts multiple things with different where cases
similar post: Query that Counts records with a WHERE clause
what I want to do is I have some... 200 groups, and within those groups are people with specific application dates. I want a count of how many people are in those groups that have a application date that falls within a specific range.
So this is the first method i've been using, but it only works for 1 group at a time
SELECT count(*) as count
FROM membersapplication ma
INNER JOIN members mb on mb.mbr_id = ma.mbr_id
WHERE (GPL_ID = 20179) and (ma.mpl_effectivedate >= '2/01/2015' and ma.mpl_effectivedate <= '4/30/2015') and (ma.mpl_cancellationdate is null)
This code takes the count of anyone that falls under GPL_ID 20179 (group placement id), i have 200 GPL_ID's that I would like this to run for, there is never a duplicate GPL_ID.
SELECT Gr.GPL_ID, Gr.GPL_Effectivedate, G.GRP_Enrolltype, G.GRP_Name, G.GRP_ID, G.GRP_Executive
FROM groupsreview gr
INNER JOIN groups g on gr.grp_ID = g.grp_ID
WHERE (GRP_ENROLLTYPE = 1) and (gp.gpl_effectivedate >= '4/30/2014' and gp.gpl_effectivedate <= '4/30/2015')
order by grp_name asc
This code gives me a list of every GPL_ID that I want (based off GRP_Enrolltype = 1) that falls within my desired date range
I basically would like to combine the two codes so that the 2nd set of code adds another column that has a count based off the fist code
Seems you really just need add GROUP BY to your query:
SELECT ma.GPL_ID, count(*) as count
FROM membersapplication ma
INNER JOIN members mb
ON mb.mbr_id = ma.mbr_id
where (ma.mpl_effectivedate >= '2/01/2015' and ma.mpl_effectivedate <= '4/30/2015')
AND (ma.mpl_cancellationdate is null)
GROUP BY ma.GPL_ID
This should do it. But I would double check the dates, I just used the ones you supplied; they don't match, and I am not sure if they should:
SELECT ma.GPL_ID, count(*) as count
FROM groups g
INNER JOIN groupsreview AS gr ON g.grp_ID = gr.grp_ID
INNER JOIN membersapplication AS ma ON gr.GPL_ID = ma.GPL_ID
INNER JOIN members AS mb ON mb.mbr_id = ma.mbr_id
WHERE g.GRP_ENROLLTYPE = 1
AND gr.gpl_effectivedate BETWEEN 20140430 AND 20150430
AND ma.mpl_effectivedate BETWEEN 20150201 and 20150430
AND ma.mpl_cancellationdate IS NULL
GROUP BY ma.GPL_ID
;
Judging from your question's wording, it feels a little odd to group by GPL_ID instead of grp_ID.
Not sure if this will work, but I can give it a try:
SELECT
*
FROM
(SELECT
count(*) as count, GPL_ID
FROM
membersapplication ma
inner join members mb ON mb.mbr_id = ma.mbr_id
where
(ma.mpl_effectivedate >= '2/01/2015'
and ma.mpl_effectivedate <= '4/30/2015')
and (ma.mpl_cancellationdate is null)
GROUP BY GPL_ID) T1
INNER JOIN
(SELECT
Gr.GPL_ID,
Gr.GPL_Effectivedate,
G.GRP_Enrolltype,
G.GRP_Name,
G.GRP_ID,
G.GRP_Executive
FROM
groupsreview gr
inner join groups g ON gr.grp_ID = g.grp_ID
WHERE
(GRP_ENROLLTYPE = 1)
and (gp.gpl_effectivedate >= '4/30/2014'
and gp.gpl_effectivedate <= '4/30/2015')) T2
ON T1.GPL_ID = T2.GPL_ID
Basically you should approach this by combining joins and then grouping on GPL_ID along with a having clause. Here's what came up with.
SELECT Gr.GPL_ID, Gr.GPL_Effectivedate, G.GRP_Enrolltype, G.GRP_Name, G.GRP_ID, G.GRP_Executive
count(*) as grp_count
FROM membersapplication ma
INNER JOIN members mb on mb.mbr_id = ma.mbr_id
INNER JOIN groupsreview gr on mb.GPL_ID = gr.GPL_ID
INNER JOIN groups g on gr.grp_ID = g.grp_ID
WHERE (GRP_ENROLLTYPE = 1) and (gp.gpl_effectivedate >= '4/30/2014' and gp.gpl_effectivedate <= '4/30/2015')
GROUP BY Gr.GPL_ID, Gr.GPL_Effectivedate, G.GRP_Enrolltype, G.GRP_Name, G.GRP_ID, G.GRP_Executive
HAVING (ma.mpl_effectivedate >= '2/01/2015' and ma.mpl_effectivedate <= '4/30/2015') and (ma.mpl_cancellationdate is null)
order by grp_name asc
Hopefully this helps
Some sql query gives me the following result:
As you can see, it already has GROUP BY.
So what I need? I need to group it again (by treatment_name) and count rows for each group. See more details on screenshot.
Here is full query:
SELECT
treatment_summaries.*
FROM `treatment_summaries`
INNER JOIN
`treatments`
ON
`treatments`.`treatment_summary_id` = `treatment_summaries`.`id`
AND
(treatment <> '' and treatment is not null)
INNER JOIN
`treatment_reviews`
ON
`treatment_reviews`.`treatment_id` = `treatments`.`id`
INNER JOIN
`conditions_treatment_reviews`
ON
`conditions_treatment_reviews`.`treatment_review_id` = `treatment_reviews`.`id`
INNER JOIN
`conditions` ON `conditions`.`id` = `conditions_treatment_reviews`.`condition_id`
INNER JOIN `conditions_treatment_summaries` `conditions_treatment_summaries_join`
ON
`conditions_treatment_summaries_join`.`treatment_summary_id` = `treatment_summaries`.`id`
INNER JOIN `conditions` `conditions_treatment_summaries`
ON `conditions_treatment_summaries`.`id` = `conditions_treatment_summaries_join`.`condition_id`
WHERE
`conditions`.`id` = 9
AND `conditions`.`id` IN (9)
AND (latest_review_id is not null)
GROUP BY
treatment_reviews.id
ORDER BY
treatment_summaries.reviews_count desc
LIMIT 20 OFFSET 0
Maybe there is another issue, cause GROUP BY should not leave same lines (for given column), but anyway you can wrap it like this:
SELECT * FROM ( YOUR_SQL_SELECT_WITH_EVERYTHING ) GROUP BY id
So the result you get will behave as another table and you can do all operations like GROUP BY again.
I am having trouble getting a MySQL query to work for me. Here is the setup.
A customer has asked me to compile a report from some accounting data. He wants to select a date (and possibly other criteria) and have it return all of the following (an OR statement):
1.) All invoices that were inserted on or after that date
2.) All invoices regardless of their insert date that have corresponding payments in a separate table whose insert dates are on or after the selected date.
The first clause is basic, but I am having trouble pairing it with the second.
I have assembled a comparable set of test data in an SQL Fiddle. The query that I currently have is provided.
http://www.sqlfiddle.com/#!2/d8d9c/3/2
As noted in the comments of the fiddle, I am working with July 1, 2013 as my selected date. For the test to work, I need invoices 1 through 5 to appear, but not invoice #6.
Try this: http://www.sqlfiddle.com/#!2/d8d9c/9
Here are the summarized changes
I got rid of your GROUP BY. You did not have any aggregate functions. I used DISTINCT instead to eliminate duplicate records
I removed your implicit joins and put explicit joins in their place for readability. Then I changed them to LEFT JOINs. I am not sure what your data looks like but at a minimum, I would assume you need the payments LEFT JOINed if you want to select an invoice that has no payments.
This will probably get you the records you want, but those subselects in the SELECT clause may perform better as LEFT JOINs then using the SUM function
Here is the query
SELECT DISTINCT
a.abbr landowner,
CONCAT(f.ForestLabel, '-', l.serial, '-', l.revision) leasenumber,
i.iid,
FROM_UNIXTIME(i.dateadded,'%M %d, %Y') InvoiceDate,
(SELECT IFNULL(SUM(ch.amount), 0.00) n FROM test_charges ch WHERE ch.invoiceid = i.iid) totalBilled,
(SELECT SUM(p1.amount) n FROM test_payments p1 WHERE p1.invoiceid = i.iid AND p1.transtype = 'check' AND p1.status = 2) checks,
(SELECT SUM(p1.amount) n FROM test_payments p1 WHERE p1.invoiceid = i.iid AND p1.transtype = 'ach' AND p1.status = 2) ach,
CASE WHEN i.totalbilled < 0 THEN i.totalbilled * -1 ELSE 0.00 END credits,
CASE WHEN i.balance >= 0 THEN i.balance ELSE 0.00 END balance,
t.typelabel, g.groupname
FROM test_invoices i
LEFT JOIN test_contracts c
ON i.contractid = c.cid
LEFT JOIN test_leases l
ON c.leaseid = l.bid
LEFT JOIN test_forest f
ON l.forest = f.ForestID
LEFT JOIN test_leasetypes t
ON l.leasetype = t.tid
LEFT JOIN test_accounts a
ON l.account = a.aid
LEFT JOIN test_groups g
ON c.groupid = g.gid
LEFT JOIN test_payments p
ON p.invoiceid = i.iid
WHERE (i.dateadded >= #startdate) OR (p.dateadded >= #startdate)
Try this.
http://www.sqlfiddle.com/#!2/d8d9c/11/2
TL;DR:
… AND (i.dateadded > #startdate
OR EXISTS (
SELECT * FROM test_payments
WHERE test_payments.invoiceid = i.iid
AND test_payments.dateadded >= #startdate))
Everything in the following query results in one line for each invBlueprintTypes row with the correct information. But I'm trying to add something to it. See below the codeblock.
Select
blueprintType.typeID,
blueprintType.typeName Blueprint,
productType.typeID,
productType.typeName Item,
productType.portionSize,
blueprintType.basePrice * 0.9 As bpoPrice,
productGroup.groupName ItemGroup,
productCategory.categoryName ItemCategory,
blueprints.productionTime,
blueprints.techLevel,
blueprints.researchProductivityTime,
blueprints.researchMaterialTime,
blueprints.researchCopyTime,
blueprints.researchTechTime,
blueprints.productivityModifier,
blueprints.materialModifier,
blueprints.wasteFactor,
blueprints.maxProductionLimit,
blueprints.blueprintTypeID
From
invBlueprintTypes As blueprints
Inner Join invTypes As blueprintType On blueprints.blueprintTypeID = blueprintType.typeID
Inner Join invTypes As productType On blueprints.productTypeID = productType.typeID
Inner Join invGroups As productGroup On productType.groupID = productGroup.groupID
Inner Join invCategories As productCategory On productGroup.categoryID = productCategory.categoryID
Where
blueprints.techLevel = 1 And
blueprintType.published = 1 And
productType.marketGroupID Is Not Null And
blueprintType.basePrice > 0
So what I need to get in here is the following table with the columns below it so I can use the values timestamp and sort the entire result by profitHour
tablename: invBlueprintTypesPrices
columns: blueprintTypeID, timestamp, profitHour
I need this information with the following select in mind. Using a select to show my intention of the JOIN/in-query select or whatever that can do this.
SELECT * FROM invBlueprintTypesPrices
WHERE blueprintTypeID = blueprintType.typeID
ORDER BY timestamp DESC LIMIT 1
And I need the main row from table invBlueprintTypes to still show even if there is no result from the invBlueprintTypesPrices. The LIMIT 1 is because I want the newest row possible, but deleting the older data is not a option since history is needed.
If I've understood correctly I think I need a subquery select, but how to do that? I've tired adding the exact query that is above with a AS blueprintPrices after the query's closing ), but did not work with a error with the
WHERE blueprintTypeID = blueprintType.typeID
part being the focus of the error. I have no idea why. Anyone who can solve this?
You'll need to use a LEFT JOIN to check for NULL values in invBlueprintTypesPrices. To mimic the LIMIT 1 per TypeId, you can use the MAX() or to truly make sure you only return a single record, use a row number -- this depends on whether you can have multiple max time stamps for each type id. Assuming not, then this should be close:
Select
...
From
invBlueprintTypes As blueprints
Inner Join invTypes As blueprintType On blueprints.blueprintTypeID = blueprintType.typeID
Inner Join invTypes As productType On blueprints.productTypeID = productType.typeID
Inner Join invGroups As productGroup On productType.groupID = productGroup.groupID
Inner Join invCategories As productCategory On productGroup.categoryID = productCategory.categoryID
Left Join (
SELECT MAX(TimeStamp) MaxTime, TypeId
FROM invBlueprintTypesPrices
GROUP BY TypeId
) blueprintTypePrice On blueprints.blueprintTypeID = blueprintTypePrice.typeID
Left Join invBlueprintTypesPrices blueprintTypePrices On
blueprintTypePrice.TypeId = blueprintTypePrices.TypeId AND
blueprintTypePrice.MaxTime = blueprintTypePrices.TimeStamp
Where
blueprints.techLevel = 1 And
blueprintType.published = 1 And
productType.marketGroupID Is Not Null And
blueprintType.basePrice > 0
Order By
blueprintTypePrices.profitHour
Assuming you might have the same max time stamp with 2 different records, replace the 2 left joins above with something similar to this getting the row number:
Left Join (
SELECT #rn:=IF(#prevTypeId=TypeId,#rn+1,1) rn,
TimeStamp,
TypeId,
profitHour,
#prevTypeId:=TypeId
FROM (SELECT *
FROM invBlueprintTypesPrices
ORDER BY TypeId, TimeStamp DESC) t
JOIN (SELECT #rn:=0) t2
) blueprintTypePrices On blueprints.blueprintTypeID = blueprintTypePrices.typeID AND blueprintTypePrices.rn=1
You don't say where you are putting the subquery. If in the select clause, then you have a problem because you are returning more than one value.
You can't put this into the from clause directly, because you have a correlated subquery (not allowed).
Instead, you can put it in like this:
from . . .
(select *
from invBLueprintTypesPrices ibptp
where ibtp.timestamp = (select ibptp2.timestamp
from invBLueprintTypesPrices ibptp2
where ibptp.blueprintTypeId = ibptp2.blueprintTypeId
order by timestamp desc
limit 1
)
) ibptp
on ibptp.blueprintTypeId = blueprintType.TypeID
This identifies the most recent records for all the blueprintTypeids in the subquery. It then joins in the one that matches.
