I have the following two queries that build/feed into the third query. My goal is to have a crosstab query of [MCOs] down the left and possible responses/values for [DrpDown] across the top with the values shown as percentages of the total for each [MCO] (so % of row total).
What I have works, but I want to know if I can do it all in one query.
SELECT tblMCOs.MCOs, tblMCOs.DrpDwn, Count(tblMCOs.ID) AS CountOfID
FROM tblMCOs
GROUP BY tblMCOs.MCOs, tblMCOs.DrpDwn;
SELECT tblMCOs.MCOs, Count(tblMCOs.DrpDwn) AS CountOfDrpDwn
FROM tblMCOs
GROUP BY tblMCOs.MCOs;
TRANSFORM Sum(Round([qryMCODrpDwnCt]![CountOfID]/[qryMCOCtDrpDwn]!
[CountOfDrpDwn],4)*100) AS PCT
SELECT qryMCODrpDwnCt.MCOs
FROM qryMCODrpDwnCt INNER JOIN qryMCOCtDrpDwn ON qryMCODrpDwnCt.MCOs =
qryMCOCtDrpDwn.MCOs
GROUP BY qryMCODrpDwnCt.MCOs
PIVOT qryMCODrpDwnCt.DrpDwn;
Thanks in advance for your help.
What I have works, but I want to know if I can do it all in one query.
Crosstab queries can be a bit fussy, but simply inserting the SQL code as subqueries should work:
TRANSFORM Sum(Round([sqMCODrpDwnCt]![CountOfID]/[sqMCOCtDrpDwn]![CountOfDrpDwn],4)*100) AS PCT
SELECT sqMCODrpDwnCt.MCOs
FROM
(
SELECT tblMCOs.MCOs, tblMCOs.DrpDwn, Count(tblMCOs.ID) AS CountOfID
FROM tblMCOs
GROUP BY tblMCOs.MCOs, tblMCOs.DrpDwn
) AS sqMCODrpDwnCt
INNER JOIN
(
SELECT tblMCOs.MCOs, Count(tblMCOs.DrpDwn) AS CountOfDrpDwn
FROM tblMCOs
GROUP BY tblMCOs.MCOs
) AS sqMCOCtDrpDwn
ON sqMCODrpDwnCt.MCOs = sqMCOCtDrpDwn.MCOs
GROUP BY sqMCODrpDwnCt.MCOs
PIVOT sqMCODrpDwnCt.DrpDwn

I am trying to subquery and aggregate in SQL after doing an initial query with multiple joins. My ultimate goal is to get a count (or a sum) of specimens tested based on a grouping of multiple columns. This is slightly different from SQL Server query - Selecting COUNT(*) with DISTINCT and SQL Server: aggregate error on grouping.
The three tables that I use (PERSON, SPECIMEN, TEST), have 1-many relationships. So PERSON has many SPECIMENS and those SPECIMENS have many TESTS. I did three inner joins to combine these tables plus an additional table (ANALYSIS).
WITH TALLY as (
SELECT PERSON.NAME, PERSON.PHASE, TEST.DATE_STARTED, TEST.ANALYSIS, SPECIMEN.GROUP, TEST.STATUS,
ANALYSIS.ANALYSIS_TYPE, SPECIMEN.SPECIMEN_NUMBER
FROM DB.TEST
INNER JOIN
DB.SAMPLE ON
TEST.SPECIMEN_NUMBER = SPECIMEN.SPECIMEN_NUMBER
INNER JOIN
DB.PRODUCT ON
SPECIMEN.PERSON = PERSON.NAME
INNER JOIN
DB.ANALYSIS ON
TEST.ANALYSIS = ANALYSIS.NAME
WHERE PERSON.NAME = 'Joe'
AND TEST.DATE_STARTED >= '20-DEC-16' AND TEST.DATE_STARTED <='01-APR-18'
AND PERSON.PHASE = 'PHASE1'
ORDER BY TEST.DATE_STARTED)
SELECT COUNT(DISTINCT ANALYSIS) as SPECIMEN_COUNT, DATE_STARTED, ANALYSIS, STATUS, GROUP, ANALYSIS_TYPE
FROM TALLY
GROUP BY DATE_STARTED, ANALYSIS, STATUS, GROUP, ANALYSIS_TYPE
ORDER BY DATE_STARTED;
This gives me the repeated columns: first grouping repeated 4 times
What I am trying to see is: aggregated first grouping with total count
Any thoughts as to what is missing? SUM instead of COUNT or in addition to COUNT creates an error. Thanks in advance!
9/17/2020 Update: I have tried adding a subquery because I also need to use a new column of metadata (ANALYSIS_TYPE_ALIAS) which is created in the first query through a CASE STATEMENT(...). I have also tried using another subquery with inner join to count based on those conditions to a temp table, but still cannot seem to aggregate to flatten the table. Here is my current attempt:
WITH TALLY as (
SELECT PERSON.NAME, PERSON.PHASE, TEST.DATE_STARTED, TEST.ANALYSIS, SPECIMEN.GROUP, TEST.STATUS,
ANALYSIS.ANALYSIS_TYPE...
FROM DB.TEST
INNER JOIN
DB.SAMPLE ON
TEST.SPECIMEN_NUMBER = SPECIMEN.SPECIMEN_NUMBER
INNER JOIN
DB.PRODUCT ON
SPECIMEN.PERSON = PERSON.NAME
INNER JOIN
DB.ANALYSIS ON
TEST.ANALYSIS = ANALYSIS.NAME
WHERE PERSON.NAME = 'Joe'
AND TEST.DATE_STARTED >= '20-DEC-16' AND TEST.DATE_STARTED <='01-APR-18'
AND PERSON.PHASE = 'PHASE1'
ORDER BY TEST.DATE_STARTED),
SUMMARY_COMBO AS (SELECT DISTINCT(CONCAT(CONCAT(CONCAT(CONCAT(ANALYSIS, DATE_STARTED),STATUS), GROUP), ANALYSIS_TYPE_ALIAS))AS UUID,
TALLY.NAME, TALLY.PHASE, TALLY.DATE_STARTED, TALLY.ANALYSIS, TALLY.GROUP, TALLY.STATUS, TALLY.ANALYSIS_TYPE_ALIAS
FROM TALLY)
SELECT SUMMARY_COMBO.NAME, SUMMARY_COMBO.PHASE, SUMMARY_COMBO.DATE_STARTED, SUMMARY_COMBO.ANALYSIS,SUMMARY_COMBO.GROUP, SUMMARY_COMBO.STATUS, SUMMARY_COMBO.ANALYSIS_TYPE_ALIAS,
COUNT(SUMMARY_COMBO.ANALYSIS) OVER (PARTITION BY SUMMARY_COMBO.UUID) AS SPECIMEN_COUNT
FROM SUMMARY_COMBO
ORDER BY SUMMARY_COMBO.DATE_STARTED;
This gave me the following table Shows aggregated counts, but doesn't aggregate based on unique UUID. Is there a way to take the sum of the count? I've tried to do this by storing count to a subquery and then referencing that count variable, but I am missing something in how to group the 8 columns of data that I want to show + the count of that combination of columns.
Thanks!
Just remove analysis from the group by clause, since that's the column whose distinct values you want to count. Otherwise, the query generates more groups than what you need (and the count of distinct analysis values in each group is always 1).
WITH TALLY as ( ...)
SELECT COUNT(DISTINCT ANALYSIS) as SPECIMEN_COUNT, DATE_STARTED, ANALYSIS, STATUS, GROUP, ANALYSIS_TYPE
FROM TALLY
GROUP BY DATE_STARTED, STATUS, GROUP, ANALYSIS_TYPE
ORDER BY DATE_STARTED;
I got help with a function yesterday to correctly get the count of multiple items in a column based on multiple criteria/columns. However, if there is a way to get the DISTINCT count of all the entries in the table based on aggregated GROUP BY statement.
SELECT TIME = ap.day,
acms.tenantId,
acms.CallingService,
policyList = ltrim(sp.value),
policyInstanceList = ltrim(dp.value),
COUNT(*) AS DISTINCTCount
FROM dbo.acms_data acms
CROSS APPLY string_split(acms.policyList, ',') sp
CROSS APPLY string_split(acms.policyInstanceList, ',') dp
CROSS APPLY (select day = convert(date, acms.[Time])) ap
GROUP BY ap.day, acms.tenantId, sp.value, dp.value, acms.CallingService
I would just like to know if there would be a way to see if there is a workaround for using DISTINCT and Count(*) together and whether or not it would affect my results to make this algorithm potentially invulnerable to duplicate entries.
The reason why I have to use COUNT(*) is because I am aggregating based on every column in the table not just a specific column or multiple.
We can use DISTINCT with COUNT together like this example.
USE AdventureWorks2012
GO
-- This query shows 290 JobTitle
SELECT COUNT(JobTitle) Total_JobTitle
FROM [HumanResources].[Employee]
GO
-- This query shows only 67 JobTitle
SELECT COUNT( DISTINCT JobTitle) Total_Distinct_JobTitle
FROM [HumanResources].[Employee]
GO
select COUNT(analysed) from Results where analysed="True"
I want to display count of rows in which analysed value is true.
However, my query gives the error: "The multi-part identifier "Results.runId" could not be bound.".
This is the actual query:
select ((SELECT COUNT(*) AS 'Count'
FROM Results
WHERE Analysed = 'True')/failCount) as PercentAnalysed
from Runs
where Runs.runId=Analysed.runId
My table schema is:
The value I want for a particular runId is: (the number of entries where analysed=true)/failCount
EDIT : How to merge these two queries?
i) select runId,Runs.prodId,prodDate,prodName,buildNumber,totalCount as TotalTestCases,(passCount*100)/(passCount+failCount) as PassPercent,
passCount,failCount,runOwner from Runs,Product where Runs.prodId=Product.prodId
ii) select (cast(counts.Count as decimal(10,4)) / cast(failCount as decimal(10,4))) as PercentAnalysed
from Runs
inner join
(
SELECT COUNT(*) AS 'Count', runId
FROM Results
WHERE Analysed = 'True'
GROUP BY runId
) counts
on counts.runId = Runs.runId
I tried this :
select runId,Runs.prodId,prodDate,prodName,buildNumber,totalCount as TotalTestCases,(passCount*100)/(passCount+failCount) as PassPercent,
passCount,failCount,runOwner,counts.runId,(cast(counts.Count as decimal(10,4)) / cast(failCount as decimal(10,4))) as PercentAnalysed
from Runs,Product
inner join
(
SELECT COUNT(*) AS 'Count', runId
FROM Results
WHERE Analysed = 'True'
GROUP BY runId
) counts
on counts.runId = Runs.runId
where Runs.prodId=Product.prodId
but it gives error.
Your problems are arising from improper joining of tables. You need information from both Runs and Results, but they aren't combined properly in your query. You have the right idea with a nested subquery, but it's in the wrong spot. You're also referencing the Analysed table in the outer where clause, but it hasn't been included in the from clause.
Try this instead:
select (cast(counts.Count as decimal(10,4)) / cast(failCount as decimal(10,4))) as PercentAnalysed
from Runs
inner join
(
SELECT COUNT(*) AS 'Count', runId
FROM Results
WHERE Analysed = 'True'
GROUP BY runId
) counts
on counts.runId = Runs.runId
I've set this up as an inner join to eliminate any runs which don't have analysed results; you can change it to a left join if you want those rows, but will need to add code to handle the null case. I've also added casts to the two numbers, because otherwise the query will perform integer division and truncate any fractional amounts.
I'd try the following query:
SELECT COUNT(*) AS 'Count'
FROM Results
WHERE Analysed = 'True'
This will count all of your rows where Analysed is 'True'. This should work if the datatype of your Analysed column is either BIT (Boolean) or STRING(VARCHAR, NVARCHAR).
Use CASE in Count
SELECT COUNT(CASE WHEN analysed='True' THEN analysed END) [COUNT]
FROM Results

select COUNT(*) from Results where analysed="True"
Hi guys, I am stuck with a stubborn problem which I am unable to solve. Am trying to compile a report wherein all the dates coming from different tables would need to come into a single date field in the report. Ofcourse, the max or the most recent date from all these date columns needs to be added to the single date column for the report. I have multiple users of multiple branches/courses for whom the report would be generated.
There are multiple blogs and the latest date w.r.t to the blogtitle needs to be grouped, i.e. max(date_value) from the six date columns should give the greatest or latest date for that blogtitle.
Expected Result:
select u.batch_uid as ext_person_key, u.user_id, cm.batch_uid as ext_crs_key, cm.crs_id, ir.role_id as
insti_role, (CASE when b.JOURNAL_IND = 'N' then
'BLOG' else 'JOURNAL' end) as item_type, gm.title as item_name, gm.disp_title as ITEM_DISP_NAME, be.blog_pk1 as be_blogPk1, bc.blog_entry_pk1 as bc_blog_entry_pk1,bc.pk1,
b.ENTRY_mod_DATE as b_ENTRY_mod_DATE ,b.CMT_mod_DATE as BlogCmtModDate, be.CMT_mod_DATE as be_cmnt_mod_Date,

I am getting a resultset for the above query with multiple date columns which I want > > to input into a single columnn. The dates have to be the most recent, i.e. max of the dates in the date columns.
I have successfully done the Unpivot by using a view to store the above
resultset and put all the dates in one column. However, I do not
want to use a view or a table to store the resultset and then do
Unipivot simply because I cannot keep creating views for every user
one would query for.
The max(date_value) from the date columns need to be put in one single column. They are as follows:
* 1) b.entry_mod_date, 2) b.cmt_mod_date ,3) be.cmt_mod_date , 4) b.update_Date ,5) be.update_date, 6) bc.creation_date *
Apologies that I could not provide the desc of all the tables and the
fields being used.
Any help to get the above mentioned max of the dates from these
multiple date columns into a single column without using a view or a
table would be greatly appreciated.*
It is not clear what results you want, but the easiest solution is to use greatest().
with t as (
YOURQUERYHERE
)
select t.*,
greatest(entry_mod_date, cmt_mod_date, cmt_mod_date, update_Date,
update_date, bc.creation_date
) as greatestdate
from t;
select <columns>,
case
when greatest (b_ENTRY_mod_DATE) >= greatest (BlogCmtModDate) and greatest(b_ENTRY_mod_DATE) >= greatest(BlogUpDate)
then greatest( b_ENTRY_mod_DATE )
--<same implementation to compare each time BlogCmtModDate and BlogUpDate separately to get the greatest then 'date'>
,<columns>
FROM table
<rest of the query>
UNION ALL
Select <columns>,
case
when greatest (be_cmnt_mod_Date) >= greatest (be_UPDATE_DATE)
then greatest( be_cmnt_mod_Date )
when greatest (be_UPDATE_DATE) >= greatest (be_cmnt_mod_Date)
then greatest( be_UPDATE_DATE )
,<columns>
FROM table
<rest of the query>
UNION ALL

I have this query in T-SQL 2008:
SELECT a.Amount / (
SELECT SUM(b.Amount) FROM Revenue b
WHERE YEAR(b.RevenueDate) = YEAR(a.ExpenseDate)
AND MONTH(b.RevenueDate) = MONTH(a.ExpenseDate)
AND b.HotelKey = a.HotelKey
)
FROM Expense a
The problem is it takes too long to finish the query. I think it's caused by the subquery "SELECT SUM(b.Amount) FROM Revenue b..." which is executed for each row in table Expense.
How to optimize that kind of query? Is there any better alternative for the query?
EDIT: I'm sorry I forget the "AND b.HotelKey = a.HotelKey" clause in the subquery. The above original query has been updated.
#damien:
Here is your query added with HotelKey join:
SELECT
a.Amount / b.Amount
FROM
Expense a
inner join
(SELECT
HotelKey,
DATEADD(month,DATEDIFF(month,0,RevenueDate),0) as MonthStart,
DATEADD(month,1+DATEDIFF(month,0,RevenueDate),0) as MonthEnd,
SUM(Amount) as Amount
FROM
Revenue
GROUP BY
HotelKey,
DATEADD(month,DATEDIFF(month,0,RevenueDate),0),
DATEADD(month,1+DATEDIFF(month,0,RevenueDate),0)
) b
ON
a.ExpenseDate >= b.MonthStart and
a.ExpenseDate < b.MonthEnd
and a.HotelKey = b.HotelKey
Try to change the where clause in your inner query to this:
where b.RevenueDate >= dateadd(month, datediff(month, 0, a.ExpenseDate), 0) and
b.RevenueDate < dateadd(month, 1+datediff(month, 0, a.ExpenseDate), 0)
It will give the query a chance to use an index on Revenue.RevenueDate if you have one.
If you're using a lot of the rows in Revenue to satisfy this query, you might do better to do a single subquery that computes all of the totals. (Also, using Mikael's suggestion for allowing some indexing to occur):
SELECT
a.Amount / b.Amount
FROM
Expense a
inner join
(SELECT
DATEADD(month,DATEDIFF(month,0,RevenueDate),0) as MonthStart,
DATEADD(month,1+DATEDIFF(month,0,RevenueDate),0) as MonthEnd
SUM(Amount) as Amount
FROM
Revenue
GROUP BY
DATEADD(month,DATEDIFF(month,0,RevenueDate),0),
DATEADD(month,1+DATEDIFF(month,0,RevenueDate),0)
) b
ON
a.ExpenseDate >= b.MonthStart and
a.ExpenseDate < b.MonthEnd
You don't specify how big the tables are. But you can get the query to be faster by creating a computed column (and indexing it) from year-month combination in table Revenue and in table Expense as well (if that table is not very small). So these computed columns (and the indexes) would be used in the query for joining the two tables.
See: Computed Columns
and: Creating Indexes on Computed Columns
You could try calculating the two sums first ant then joining the two together afterwards.
SELECT a.ExpenseAmount / b.RevenueAmount
FROM
(
SELECT SUM(Expense.Amount) As ExpenseAmount,
YEAR(Expense.ExpenseDate) AS ExpenseYear,
MONTH(Expense.ExpenseDate) AS ExpenseMonth
GROUP BY
YEAR(Expense.RevenueDate),
MONTH(Expense.RevenueDate)
) AS a INNER JOIN
(
SELECT SUM(Revenue.Amount) AS RevenueAmount,
YEAR(Revenue.RevenueDate) AS RevenueYear,
MONTH(Revenue.RevenueDate) AS RevenueMonth
FROM Revenue
GROUP BY YEAR(Revenue.RevenueDate), MONTH(Revenue.RevenueDate)
) as b ON a.ExpenseYear = b.RevenueYear AND a.ExpenseMonth = b.ExpenseMonth
