Have Query Results Display In Different Columns - sql-server-2008

I am trying to avoid the creation of a table to have these results display (if possible). What I want to do is to essentially have the look of a table with my query results and have a column for fullitemlist, a column for 'has been ordered' and a column for 'has not been ordered'. Essentially I am trying to have a result set like such returned from my query:
> Zip = 55555
> fullitemlist ----- Has Been Ordered ---- Has Not Been Ordered
> Knife Set 1 0
> Butcher Block 0 1
> Dishwasher 0 1
> Hair Dryer 1 0
so on and so forth for all items in my tbl_itemlist. This is the 3 CTE queries I was trying to work with, but it returns everything in one giant list, not what I was after :)
Declare #zip varchar(5)
Set #zip = '55555'
;With CTE As
(
Select fullitemlist from tbl_ItemList
Where zip = #zip
)
,CTE2 As
(
Select case when hasbeenordered = 1 then 1 else 0 end as 'Has Been Ordered' from tbl_purchasehistory
WHERE itemid IN (Select itemid from tbl_ItemList where hasbeenordered = 1 and zip = #zip)
)
,CTE3 As
(
Select case when hasbeenordered = 0 then 1 else 0 end as as 'Has NEVER Been Ordered' from tbl_purchasehistory
WHERE itemid IN (Select itemid from tbl_ItemList where hasbeenordered = 0 and zip = #zip)
)
SELECT * from CTE
UNION ALL
SELECT * FROM CTE2
UNION ALL
SELECT * FROM CTE3

-- you may write your query like this according to your question instead of CTE ,union all,SubQuery this is the simplest way .
SELECT fullitemlist
,CASE
WHEN tp.hasbeenordered = 1
AND tI.hasbeenordered = 1
THEN 1
ELSE 0
END AS 'Has Been Ordered'
,CASE
WHEN tp.hasbeenordered = 0
AND ti.tp.hasbeenordered = 0
THEN 1
ELSE 0
END AS 'Has NEVER Been Ordered'
FROM tbl_ItemList ti
INNER JOIN tbl_purchasehistory tp ON ti.itemid = tp.ItemId
WHERE zip = #zip

Return 1 or 0 in SQL depending on the multiple statements

If I find that some of the user exists with such a parameters, I want to get 1 otherwise 0. In the future I'll have to add more blocks. But it doesn't seem to work now. What am I doing wrong?
SELECT CAST(CASE WHEN EXISTS(SELECT 1
FROM Customers
WHERE Country = 'France' AND PostalCode%2 = 0)
OR (WHERE Country = 'Germany' AND PostalCode%2 = 0))
)
THEN 1
ELSE 0
END AS BIT)
You need two separate exists:
SELECT CAST(CASE WHEN EXISTS (SELECT 1
FROM Customers
WHERE Country = 'France' AND PostalCode%2 = 0
)
THEN 1
WHEN EXISTS (SELECT 1
FROM Customers
WHERE Country = 'Germany' AND PostalCode%2 = 0
)
THEN 1
ELSE 0
END AS BIT)
Actually, I broke this into two separate THEN clauses. This is almost equivalent to using OR, but because the logic is inside a CASE, THEN seems more natural. (The difference is that the optimizer could choose to re-arrange the OR conditions, but the THEN conditions are executed in lexical order.)
If your statements are actually this simple, you can combine them as:
SELECT CAST(CASE WHEN EXISTS (SELECT 1
FROM Customers
WHERE Country IN ('France', 'Germany') AND PostalCode%2 = 0
)
THEN 1
ELSE 0
END AS BIT)
It looks to me like you're just having issues with your bracketing:
SELECT CAST(
CASE WHEN EXISTS(
SELECT 1
FROM Customers
WHERE (Country = 'France' AND PostalCode%2 = 0)
OR (Country = 'Germany' AND PostalCode%2 = 0)
) THEN 1 ELSE 0 END AS BIT)
Building on Gordon's assumption that PostalCode%2 = 0 for all tested 'sets' of conditionals (you haven't said as much yet), you could likewise shorten this to:
SELECT CAST(
CASE WHEN EXISTS(
SELECT 1
FROM Customers
WHERE PostalCode%2 = 0
AND Country IN ('France', 'Germany')
) THEN 1 ELSE 0 END AS BIT)

Excluding email lists while selecting specific values at once

I am trying to do 2 things here within 1 SELECT query (I know I could do this in 2 steps but I want to avoid intermediary tables):
Select specific values (M and W only — there are other values possible but I just want these 2 and not other) from a TABLE 'anothertable'.
While avoiding selecting opt-outs and bounced emails (11k rows, <5 columns).
I am not sure if the syntax is correct since the query is loading for ever. Size should not be an issue though (27k rows, <5 columns and 2 core processors).
BEGIN
CREATE TABLE `mytable` AS (
SELECT * FROM `anothertable` A
WHERE NOT EXISTS (SELECT Email FROM `optout` B WHERE B.Email = A.Email)
AND NOT EXISTS (SELECT Email FROM `allbounced` C WHERE C.emailbounced = A.Email)
GROUP BY Email
HAVING
(SUM(CASE WHEN target = 'M' THEN 1 ELSE 0 END) > 0 OR -- MAN is present
SUM(CASE WHEN target = 'W' THEN 1 ELSE 0 END) > 0 AND -- WOMAN is present
SUM(CASE WHEN target NOT IN ('M', 'W') THEN 1 ELSE 0 END) = 0) -- only MAN or WOMAN
);
END
When possible you should use NOT IN instead of NOT EXISTS. This should be faster:
BEGIN
CREATE TABLE `mytable` AS (
SELECT Email FROM `anothertable` A
WHERE Email NOT IN (SELECT Email FROM `optout`)
AND Email NOT IN (SELECT emailbounced FROM `allbounced`)
GROUP BY Email
HAVING
(SUM(CASE WHEN target = 'M' THEN 1 ELSE 0 END) > 0 OR -- MAN is present
SUM(CASE WHEN target = 'W' THEN 1 ELSE 0 END) > 0 AND -- WOMAN is present
SUM(CASE WHEN target NOT IN ('M', 'W') THEN 1 ELSE 0 END) = 0) -- only MAN or WOMAN
);
END

SQL Server Row totals in pivot query

I am trying to make a row in the end of the result set that shows the totals.
My query is this:
SELECT
[ ] = ISNULL(CAST(GEN_idPaciente AS VARCHAR)+'-'+nombrePaciente, 'TOTAL'),
[2016-11-01] = MAX([2016-11-01]),
[2016-11-02] = MAX([2016-11-02]),
[2016-11-03] = MAX([2016-11-03]),
[2016-11-04] = MAX([2016-11-04]),
TOTAL = COUNT([2016-11-01]) + COUNT([2016-11-02]) + COUNT([2016-11-03]) + COUNT([2016-11-04])
FROM
(
SELECT GEN_Paciente.GEN_idPaciente,COALESCE(GEN_ape_paternoPaciente, '')+' '+COALESCE(GEN_ape_maternoPaciente, '')+' '+COALESCE(GEN_nombrePaciente, '') AS nombrePaciente,HOS_fechaCategorizacion,HOS_nivel_riesgoCategorizacion+CAST(HOS_nivel_dependenciaCategorizacion AS VARCHAR) as riesgoDependencia
FROM HOS_Categorizacion
INNER JOIN HOS_Hospitalizacion
ON HOS_Hospitalizacion.HOS_idHospitalizacion = HOS_Categorizacion.HOS_idHospitalizacion
INNER JOIN GEN_Paciente
ON GEN_Paciente.GEN_idPaciente = HOS_Hospitalizacion.GEN_idPaciente
WHERE HOS_nivel_riesgoCategorizacion IS NOT NULL
) src
PIVOT
(
MAX(riesgoDependencia)
for HOS_fechaCategorizacion in ([2016-11-01],[2016-11-02],[2016-11-03],[2016-11-04])
) p
GROUP BY
ROLLUP(CAST(GEN_idPaciente AS VARCHAR)+'-'+nombrePaciente)
This gives me this result:
But as you can see the totals for the rows are right but the totals for the columns are wrong because I am using MAX instead of COUNT, but I only need COUNT in the TOTAL row, the others have to be MAX, so I wrote this query:
SELECT
[ ] = ISNULL(CAST(GEN_idPaciente AS VARCHAR)+'-'+nombrePaciente, 'TOTAL'),
[2016-11-01] = CASE WHEN CAST(GEN_idPaciente AS VARCHAR)+'-'+nombrePaciente IS NOT NULL THEN MAX([2016-11-01]) ELSE COUNT([2016-11-01]) END,
[2016-11-02] = CASE WHEN CAST(GEN_idPaciente AS VARCHAR)+'-'+nombrePaciente IS NOT NULL THEN MAX([2016-11-02]) ELSE COUNT([2016-11-02]) END,
[2016-11-03] = CASE WHEN CAST(GEN_idPaciente AS VARCHAR)+'-'+nombrePaciente IS NOT NULL THEN MAX([2016-11-03]) ELSE COUNT([2016-11-03]) END,
[2016-11-04] = CASE WHEN CAST(GEN_idPaciente AS VARCHAR)+'-'+nombrePaciente IS NOT NULL THEN MAX([2016-11-04]) ELSE COUNT([2016-11-04]) END,
TOTAL = COUNT([2016-11-01]) + COUNT([2016-11-02]) + COUNT([2016-11-03]) + COUNT([2016-11-04])
FROM
(
SELECT GEN_Paciente.GEN_idPaciente,COALESCE(GEN_ape_paternoPaciente, '')+' '+COALESCE(GEN_ape_maternoPaciente, '')+' '+COALESCE(GEN_nombrePaciente, '') AS nombrePaciente,HOS_fechaCategorizacion,HOS_nivel_riesgoCategorizacion+CAST(HOS_nivel_dependenciaCategorizacion AS VARCHAR) as riesgoDependencia
FROM HOS_Categorizacion
INNER JOIN HOS_Hospitalizacion
ON HOS_Hospitalizacion.HOS_idHospitalizacion = HOS_Categorizacion.HOS_idHospitalizacion
INNER JOIN GEN_Paciente
ON GEN_Paciente.GEN_idPaciente = HOS_Hospitalizacion.GEN_idPaciente
WHERE HOS_nivel_riesgoCategorizacion IS NOT NULL
) src
PIVOT
(
MAX(riesgoDependencia)
for HOS_fechaCategorizacion in ([2016-11-01],[2016-11-02],[2016-11-03],[2016-11-04])
) p
GROUP BY
ROLLUP(CAST(GEN_idPaciente AS VARCHAR)+'-'+nombrePaciente)
But that is not working
Thanks for your help!!
If I understand this correctly you want to count all columns which are not null. In this case you should just look at the condition IS NULL and not at the actual value at all. Try this:
DECLARE #tbl TABLE(ID INT IDENTITY, val1 VARCHAR(100),val2 VARCHAR(100),val3 VARCHAR(100));
INSERT INTO #tbl VALUES
('row1_val1','row1_val2',NULL)
,('row2_val1','row2_val2','row2_val3')
,(NULL,'row2_val2',NULL)
,(NULL,NULL,'row2_val3')
,(NULL,NULL,NULL);
SELECT *
,CASE WHEN val1 IS NULL THEN 0 ELSE 1 END
+CASE WHEN val2 IS NULL THEN 0 ELSE 1 END
+CASE WHEN val3 IS NULL THEN 0 ELSE 1 END AS CountOfValNotNull
FROM #tbl
UPDATE: Add a final Totals Row
You'd need ugly fiddling with a CTE, an additional sort column, UNION ALL to add another row and a sub_select.
Use the outer-most ORDER BY to get the artificial Totals-Row to the end
hint: Use the #tbl variable from above!
WITH SortedRows AS
(
SELECT ROW_NUMBER() OVER(ORDER BY ID) AS SortColumn
,*
,CASE WHEN val1 IS NULL THEN 0 ELSE 1 END
+CASE WHEN val2 IS NULL THEN 0 ELSE 1 END
+CASE WHEN val3 IS NULL THEN 0 ELSE 1 END AS CountOfValNotNull
FROM #tbl
)
SELECT tbl1.*
FROM
(
SELECT * FROM SortedRows
UNION ALL
SELECT 999999,0,'','','',(SELECT SUM(CountOfValNotNull) FROM SortedRows)
) AS tbl1
ORDER BY tbl1.SortColumn

How to split SQL query results into columns based on two WHERE conditions and two calculated COUNT fields?

I have the following (simplified) database schema:
Persons:
[Id] [Name]
-------------------
1 'Peter'
2 'John'
3 'Anna'
Items:
[Id] [ItemName] [ItemStatus]
-------------------
10 'Cake' 1
20 'Dog' 2
ItemDocuments:
[Id] [ItemId] [DocumentName] [Date]
-------------------
101 10 'CakeDocument1' '2016-01-01 00:00:00'
201 20 'DogDocument1' '2016-02-02 00:00:00'
301 10 'CakeDocument2' '2016-03-03 00:00:00'
401 20 'DogDocument2' '2016-04-04 00:00:00'
DocumentProcessors:
[PersonId] [DocumentId]
-------------------
1 101
1 201
2 301
I have also set up an SQL fiddle to play with: http://www.sqlfiddle.com/#!3/e6082
The relation logic is the following: every Person can work on zero or infinite number of ItemDocuments (many-to-many); each ItemDocument belongs to exactly one Item (one-to-many). Item has status 1 - Active, 2 - Closed
What I need is a report that fulfills the following requirements:
for each person in Persons table, display count of Items that have ItemDocuments related to this person
the counts should be split in two columns by ItemStatus
the query should be filterable by two optional date periods (using two BETWEEN conditions on ItemDocuments.Date field) and the Item counts should also be split into two periods
if a Person does not have any ItemDocuments assigned, it still should be shown in the results with all count values set to 0
if a Person has more than one ItemDocument for an Item, the Item still should be counted only once
Essentially, here is how the results should look like if I use both periods to NULL (to read all the data):
[PersonName] [Active Items for period 1] [Closed Items for period 1] [Active Items for period 2] [Closed Items for period 2]
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
'Peter' 1 1 1 1
'John' 1 0 1 0
'Anna' 0 0 0 0
While I can create an SQL query for each requirement separately, I have a problem to understand how to combine all of them together into one.
For example, I can split ItemStatus counts in two columns using
COUNT(CASE WHEN t.ItemStatus = 1 THEN 1 ELSE NULL END) AS Active,
COUNT(CASE WHEN t.ItemStatus = 2 THEN 1 ELSE NULL END) AS Closed
and I can filter by two periods (with max/min date constants from MS SQL server specification to avoid NULLs for optional period dates) using
between coalesce(#start1, '1753-01-01') and coalesce(#end1, '9999-12-31')
between coalesce(#start2, '1753-01-01') and coalesce(#end2, '9999-12-31')
but how to combine all of this together, considering also JOINs between tables?
Is there any technique, join or MS SQL Server specific approach to do this in efficient way?
My first attempt seems to work as required but it looks like ugly subquery duplications multiple times:
DECLARE #start1 DATETIME, #start2 DATETIME, #end1 DATETIME, #end2 DATETIME
-- SET #start2 = '2017-01-01'
SELECT
p.Name,
(SELECT COUNT(1)
FROM Items i
WHERE i.ItemStatus = 1 AND EXISTS(
SELECT 1
FROM DocumentProcessors AS dcp
INNER JOIN ItemDocuments AS idc ON dcp.DocumentId = idc.Id
WHERE dcp.PersonId = p.Id AND idc.ItemId = i.Id
AND idc.Date BETWEEN COALESCE(#start1, '1753-01-01') AND COALESCE(#end1, '9999-12-31')
)
) AS Active1,
(SELECT COUNT(*)
FROM Items i
WHERE i.ItemStatus = 2 AND EXISTS(
SELECT 1
FROM DocumentProcessors AS dcp
INNER JOIN ItemDocuments AS idc ON dcp.DocumentId = idc.Id
WHERE dcp.PersonId = p.Id AND idc.ItemId = i.Id
AND idc.Date BETWEEN COALESCE(#start1, '1753-01-01') AND COALESCE(#end1, '9999-12-31')
)
) AS Closed1,
(SELECT COUNT(1)
FROM Items i
WHERE i.ItemStatus = 1 AND EXISTS(
SELECT 1
FROM DocumentProcessors AS dcp
INNER JOIN ItemDocuments AS idc ON dcp.DocumentId = idc.Id
WHERE dcp.PersonId = p.Id AND idc.ItemId = i.Id
AND idc.Date BETWEEN COALESCE(#start2, '1753-01-01') AND COALESCE(#end2, '9999-12-31')
)
) AS Active2,
(SELECT COUNT(*)
FROM Items i
WHERE i.ItemStatus = 2 AND EXISTS(
SELECT 1
FROM DocumentProcessors AS dcp
INNER JOIN ItemDocuments AS idc ON dcp.DocumentId = idc.Id
WHERE dcp.PersonId = p.Id AND idc.ItemId = i.Id
AND idc.Date BETWEEN COALESCE(#start2, '1753-01-01') AND COALESCE(#end2, '9999-12-31')
)
) AS Closed2
FROM Persons p
I'm not absolutely sure if I really got what you want, but you might try this
WITH AllData AS
(
SELECT p.Id AS PersonId
,p.Name AS Person
,id.Date AS DocDate
,id.DocumentName AS DocName
,i.ItemName AS ItemName
,i.ItemStatus AS ItemStatus
,CASE WHEN id.Date BETWEEN COALESCE(#start1, '1753-01-01') AND COALESCE(#end1, '9999-12-31') THEN 1 ELSE 0 END AS InPeriod1
,CASE WHEN id.Date BETWEEN COALESCE(#start2, '1753-01-01') AND COALESCE(#end2, '9999-12-31') THEN 1 ELSE 0 END AS InPeriod2
FROM Persons AS p
LEFT JOIN DocumentProcessors AS dp ON p.Id=dp.PersonId
LEFT JOIN ItemDocuments AS id ON dp.DocumentId=id.Id
LEFT JOIN Items AS i ON id.ItemId=i.Id
)
SELECT PersonID
,Person
,COUNT(CASE WHEN ItemStatus = 1 AND InPeriod1 = 1 THEN 1 ELSE NULL END) AS ActiveIn1
,COUNT(CASE WHEN ItemStatus = 2 AND InPeriod1 = 1 THEN 1 ELSE NULL END) AS ClosedIn1
,COUNT(CASE WHEN ItemStatus = 1 AND InPeriod2 = 1 THEN 1 ELSE NULL END) AS ActiveIn2
,COUNT(CASE WHEN ItemStatus = 2 AND InPeriod2 = 1 THEN 1 ELSE NULL END) AS ClosedIn2
FROM AllData
GROUP BY PersonID,Person

How to use user variable as counter with inner join queries that contains GROUP BY statement?

I have 2 tables odds and matches :
matches : has match_id and match_date
odds : has id, timestamp, result, odd_value, user_id, match_id
I had a query that get the following information from those tables for each user:
winnings : the winning bets for each user. (when odds.result = 1)
loses : the lost bets for each user.(when odds.result != 1)
points : the points of each user.(the sum of the odds.odd_value) for each user.
bonus : for each continuous 5 winnings i want to add extra bonus to this variable. (for each user)
How to calculate bonus?
I tried to use this query and I faced a problem : (you can check it here SQL Fiddle)
the calculated bonus are not right for all the users :
first user:(winnings:13, bonus=2).
second user:(winnings:8, bonus=2)bonus here should be 1.
third user:(winnings:14, bonus=3)bonus here should be 2.
why does the query not calculate the bonus correctly?
select d.user_id,
sum(case when d.result = 1 then 1 else 0 end) as winnings,
sum(case when d.result = 2 then 1 else 0 end) as loses,
sum(case when d.result = 1 then d.odd_value else 0 end) as points,
f.bonus
FROM odds d
INNER JOIN
(
SELECT
user_id,SUM(CASE WHEN F1=5 THEN 1 ELSE 0 END) AS bonus
FROM
(
SELECT
user_id,
CASE WHEN result=1 and #counter<5 THEN #counter:=#counter+1 WHEN result=1 and #counter=5 THEN #counter:=1 ELSE #counter:=0 END AS F1
FROM odds o
cross join (SELECT #counter:=0) AS t
INNER JOIN matches mc on mc.match_id = o.match_id
WHERE MONTH(STR_TO_DATE(mc.match_date, '%Y-%m-%d')) = 2 AND
YEAR(STR_TO_DATE(mc.match_date, '%Y-%m-%d')) = 2015 AND
(YEAR(o.timestamp)=2015 AND MONTH(o.timestamp) = 02)
) Temp
group by user_id
)as f on f.user_id = d.user_id
group by d.user_id
I am not sure how your result related to matches table,
you can add back WHERE / INNER JOIN clause if you need.
Here is link to fiddle
and the last iteration according to your comments:
And here is a query:
SET #user:=0;
select d.user_id,
sum(case when d.result = 1 then 1 else 0 end) as winnings,
sum(case when d.result = 2 then 1 else 0 end) as loses,
sum(case when d.result = 1 then d.odd_value else 0 end) as points,
f.bonus
FROM odds d
INNER JOIN
(
SELECT
user_id,SUM(bonus) AS bonus
FROM
(
SELECT
user_id,
CASE WHEN result=1 and #counter<5 AND #user=user_id THEN #counter:=#counter+1
WHEN result=1 and #counter=5 AND #user=user_id THEN #counter:=1
WHEN result=1 and #user<>user_id THEN #counter:=1
ELSE
#counter:=0
END AS F1,
#user:=user_id,
CASE WHEN #counter=5 THEN 1 ELSE 0 END AS bonus
FROM odds o
ORDER BY user_id , match_id
) Temp
group by user_id
)as f on f.user_id = d.user_id
group by d.user_id
