SQL Union Query - sql

SELECT pv.PropertyID, COUNT(pv.VisitID) AS InitialVisit
FROM tblPAppointments pa INNER JOIN tblPropertyVisit pv ON pv.AppID = pa.AppID
WHERE pv.Status = 0
GROUP BY pv.PropertyID
UNION ALL
SELECT jv.PropertyID, COUNT(jv.JobVistID) AS JobVisit
FROM tblPAppointments pa INNER JOIN tblJobVisits jv ON jv.AppID = pa.AppID
WHERE jv.VisitStatus = 1
GROUP BY jv.PropertyID
I need to get InitialVisit count and JobVisit count in two separate columns.above query returns just two columns (PropertyID,InitialVisit).

Use a NULL as a placeholder for the column that there won't be any output for:
SELECT pv.PropertyID,
COUNT(pv.VisitID) AS InitialVisit,
NULL AS jobvisit
FROM tblPAppointments pa
JOIN tblPropertyVisit pv ON pv.AppID = pa.AppID
WHERE pv.Status = 0
GROUP BY pv.PropertyID
UNION ALL
SELECT jv.PropertyID,
NULL AS initialvisit,
COUNT(jv.JobVistID) AS JobVisit
FROM tblPAppointments pa
JOIN tblJobVisits jv ON jv.AppID = pa.AppID
WHERE jv.VisitStatus = 1
GROUP BY jv.PropertyID
This will return three columns. The column alias is necessary in the first query, but not in the second -- I aliased both to make it clear what is happening.
Be aware that using NULL like this in SQL Server will require you to use CAST/CONVERT on the NULL for data types other than INT because SQL Server defaults the NULL to an INT data type (as odd as that is).
An alternate query that doesn't use UNION:
SELECT x.propertyid,
COUNT(y.visitid) AS initialvisit,
COUNT(z.jobvisitid) AS jobvisit
FROM (SELECT pv.propertyid
FROM TBLPROPERTYVISIT pv
WHERE EXISTS (SELECT NULL
FROM TBLAPPOINTMENTS a
WHERE a.appid = pv.appid)
UNION
SELECT jv.propertyid
FROM TBLJOBVISIT jv
WHERE EXISTS (SELECT NULL
FROM TBLAPPOINTMENTS a
WHERE a.appid = jv.appid)) x
LEFT JOIN TBLPROPERTYVISIT y ON y.propertyid = x.propertyid
LEFT JOIN TBLJOBVISIT z ON z.propertyid = x.propertyid
GROUP BY x.propertyid

No need for a UNION at all. And you don't use tblPAppointments either
Edited to allow for no rows in one of the tables. Still one row output though
SELECT
ISNULL(pv2.PropertyID, jv2.PropertyID),
ISNULL(pv2.InitialVisit, 0),
ISNULL(jv2.JobVisit, 0)
FROM
(
SELECT pv.PropertyID, COUNT(pv.VisitID) AS InitialVisit
FROM tblPropertyVisit pv
WHERE pv.Status = 0
GROUP BY pv.PropertyID
) pv2
FULL OUTER JOIN
(
SELECT jv.PropertyID, COUNT(jv.JobVistID) AS JobVisit
FROM tblJobVisits jv
WHERE jv.VisitStatus = 1
GROUP BY jv.PropertyID
) jv2 ON pv2.PropertyID = jv2.PropertyID

T-SQL Full Outer Join (sample provided)

I have some issues getting a full outer join to work in T-SQL. The left outer join part seems to be working okay, but the right outer join doesn't work as expected. Here's some sample data to test this on:
I have a table A with the following columns and data. The row marked with red is the row that cannot be found in table B.
And a second table B with the following columns and data. The rows marked with yellow are the rows that cannot be found in table A.
I am trying to join the tables using the following sql code:
select tableA.klientnr, tableA.uttakstype, tableA.uttaksnr, tableA.vareanr TableAItem,tableB.vareanr tableBitem, tableA.kvantum tableAquantity, tableB.totkvant tableBquantity
from tableA as tableA
full outer join tableB as tableB on tableA.klientnr=tableB.klientnr and tableA.uttakstype=tableB.uttakstype and tableA.uttaksnr=tableB.uttaksnr and tableA.vareanr=tableB.vareanr and tableB.IsDeleted=0
where tableA.UttaksNr=639779 and tableA.IsDeleted=0
The result of the sql is the following image. The row marked in red is the extra row from tableA that does show up, but I can't get the rows from table B to show up
Expected to have 2 extra rows
550 SA 639779 NULL 100059 NULL 0
550 SA 639779 NULL 103040 NULL 14
Later edit:
Would this be correct way to handle the full outer join where there's the header/line type of structure? Or can the query be optimized?

Filtering with full join is really tricky. Your where criteria are actually turning the full join into a left join.
You can do what you want by filtering before the join:
select a.klientnr, a.uttakstype, a.uttaksnr, a.vareanr a.tableAitem,
b.vareanr b.tableBitem, a.kvantum a.tableAquantity, b.totkvant b.tableBquantity
from (select a.*
from tableA a
where a.UttaksNr = 639779 and a.IsDeleted = 0
) a full join
(select b.*
from tableB b
where b.IsDeleted = 0
) b
on a.klientnr = b.klientnr and
a.uttakstype= b.uttakstype and
a.uttaksnr = b.uttaksnr and
a.vareanr = b.vareanr;

PIVOT on multiple columns SQL server (Aspen Relay Database)

I'm using a vendor supplied Relay Database (Aspen), which is running on MS SQL server). I'm attempting to write a pivot query that needs to pivot on 2 columns.
I created a temp table since the data is across multiple tables.
WITH TEMP_TABLE AS (
SELECT
R.LOCATIONID LLOCATIONID, R.ID RID, s.groupname SGROUPNAME,t.settingname TSETTINGNAME, s.setting SSETTING
from tsetting1 s
inner join tsettype1 t on t.relaytype=s.relaytype and t.groupname = s.groupname and t.rownumber = s.rownumber
INNER JOIN TREQUEST Q ON S.REQUESTID = Q.ID
INNER JOIN TRELAY R ON R.ID = Q.RELAYID
INNER JOIN TLOCATION L ON L.ID = R.LOCATIONID
where s.requestid=29117
)
select * from TEMP_TABLE
That select all from Temp returns 38 rows of data, a subset is shown here:
RID -----SGROUPNAME------TSETTINGNAME-------SSETTING
31297 LOAD1 ENABLE TRUE
31297 LOAD1 ANGLE 60
31297 LOAD2 CALCULATED_LOAD 12269
ETC....
I added this pivot, which gets me close:
PIVOT (MAX(SSETTING) FOR TSETTINGNAME IN (ENABLE, REACH, ANGLE, CALCULATED_LOADABILITY, ZLE, CTR, PTR, KVNOM, PICKUP, PERCENTAGE)) P
Returned result from Pivot:
RID-----SGROUPNAME-----ENABLE----REACH----ANGLE----CALCULATED_LOADABILITY
31297 LOAD1 TRUE 15 60 9444
31297 LOAD2 TRUE 10 30 12269
31297 LOAD3 TRUE 20 60 14167
ETC...
I would like to have the data as 1 record for RID 31297, where LOAD1-ENABLE, LOAD2-ENABLE, LOAD3-ENABLE, LOAD1-REACH, ETC. are all headers.
I've tried multiple pivots and cross apply, but I can't seem to get the data to display correctly.
Let me know if anything is unclear or if you need more information. Any help will be greatly appreciated.
Thanks,
Joe C.
It may be easier with a bunch of case statements and a group by RID. By the way this is the "original" method of pivoting before PIVOT was implemented.
select RID
, Load1_Enable = MAX(case when SGROUPNAME = 'Load1' then enable else null end)
, Load2_Enable = MAX(case when SGROUPNAME = 'Load2' then enable else null end)
from [YourTable]
group by RID
I would go all the way to the first cte though:
WITH TEMP_TABLE AS (
SELECT
R.LOCATIONID LLOCATIONID, R.ID RID, s.groupname SGROUPNAME,t.settingname TSETTINGNAME, s.setting SSETTING
from tsetting1 s
inner join tsettype1 t on t.relaytype=s.relaytype and t.groupname = s.groupname and t.rownumber = s.rownumber
INNER JOIN TREQUEST Q ON S.REQUESTID = Q.ID
INNER JOIN TRELAY R ON R.ID = Q.RELAYID
INNER JOIN TLOCATION L ON L.ID = R.LOCATIONID
where s.requestid=29117
)
select RID
,Load1_Enable = MAX(case when SGROUPNAME = 'Load1' and TSETTINGNAME = 'Enable' then SSETTING else null end)
from TEMP_TABLE
group by RID
Note MAX is only there for an aggregate -- you should be aggregating only one record.

How to use alias of a subquery to get the running total?

I have a UNION of 3 tables for calculating some balance and I need to get the running SUM of that balance but I can't use PARTITION OVER, because I must do it with a sql query that can work in Access.
My problem is that I cannot use JOIN on an alias subquery, it won't work.
How can I use alias in a JOIN to get the running total?
Or any other way to get the SUM that is not with PARTITION OVER, because it does not exist in Access.
This is my code so far:
SELECT korisnik_id, imePrezime, datum, Dug, Pot, (Dug - Pot) AS Balance
FROM (
SELECT korisnik_id, k.imePrezime, r.datum, SUM(IIF(u.jedinstven = 1, r.cena, k.kvadratura * r.cena)) AS Dug, '0' AS Pot
FROM Racun r
INNER JOIN Usluge u ON r.usluga_id = u.ID
INNER JOIN Korisnik k ON r.korisnik_id = k.ID
WHERE korisnik_id = 1
AND r.zgrada_id = 1
AND r.mesec = 1
AND r.godina = 2017
GROUP BY korisnik_id, k.imePrezime, r.datum
UNION ALL
SELECT korisnik_id, k.imePrezime, rp.datum, SUM(IIF(u.jedinstven = 1, rp.cena, k.kvadratura * rp.cena)) AS Dug, '0' AS Pot
FROM RacunP rp
INNER JOIN Usluge u ON rp.usluga_id = u.ID
INNER JOIN Korisnik k ON rp.korisnik_id = k.ID
WHERE korisnik_id = 1
AND rp.zgrada_id = 1
AND rp.mesec = 1
AND rp.godina = 2017
GROUP BY korisnik_id, k.imePrezime, rp.datum
UNION ALL
SELECT uu.korisnik_id, k.imePrezime, uu.datum, '0' AS Dug, SUM(uu.iznos) AS Pot
FROM UnosUplata uu
INNER JOIN Korisnik k ON uu.korisnik_id = k.ID
WHERE korisnik_id = 1
GROUP BY uu.korisnik_id, k.imePrezime, uu.datum
) AS a
ORDER BY korisnik_id
You can save a query (let's name it Query1) for the UNION of the 3 tables and then create another query that returns each row in the first query and calculates the sum of the rows that are before it (optionally checking that they are in the same group).
It should be something like this:
SELECT *, (
SELECT SUM(Value) FROM Query1 AS b
WHERE b.GroupNumber=a.GroupNumber
AND b.Position<=a.Position
) AS RunningSum
FROM Query1 AS a
However, it's more efficient to do that in the report.

Selecting fields from second table in left join

The fields c.Mcc and c.Mnc in outer select are not getting populated eventhough I have those fields in bd:RawDebug.CarrierDetails.
Any help would be appreciated.
SELECT d.Id, d.DebugReason, d.DebugData, d.d1, d.d2, c.Mcc, c.Mnc
FROM
(SELECT
Id, DebugReason, DebugData,
INTEGER(SUBSTR(DebugData,0,3)) AS d1,
SUBSTR(REGEXP_REPLACE(DebugData,'[^a-zA-Z0-9]',' '),4,LENGTH(DebugData)-3) as d2
FROM TABLE_DATE_RANGE([bd:RawDebug.T],TIMESTAMP('2016-05-16'),TIMESTAMP('2016-05-16'))
WHERE DebugReason = 50013 and Id = 550661626 LIMIT 50) AS d
LEFT JOIN
(
SELECT Network, Mcc, STRING(Mnc) as Mnc from [bd:RawDebug.CarrierDetails]
) AS c
ON c.Mcc = d.d1 and c.Mnc = d.d2
LIMIT 50
If c.Mcc and c.Mnc are NULL in your results, yet that have a value in the [bd:RawDebug.CarrierDetails] table, then the only explanation is the LEFT JOIN criteria. You should look again at the condition ON c.Mcc = d.d1 and c.Mnc = d.d2 and ensure this really does match with your data in [bd:RawDebug.CarrierDetails]

How To Combine These 2 Queries into one Query without using union

SELECT b.KPCNO
,b.KPC_FULL_NAME
FROM xxkpc_hr_personnel_v2 b
WHERE b.type(+) = 'KPC Employee'
AND b.DESIGNATION is null
AND b.kpcno IS NOT NULL
AND b.ORGANIZATION_ID=(select g.ORGANIZATION_ID from xxkpc_fn_web_personnel_v g where g.kpcno = :kpcno)
GROUP BY b.KPCNO
,b.kpc_full_name
UNION
SELECT b.KPCNO
,b.KPC_FULL_NAME
FROM xxkpc_hr_pos_struct_code_comb a
,xxkpc_hr_personnel_v2 b
WHERE b.position_id(+) = a.child_position_id
AND b.type(+) = 'KPC Employee'
AND b.kpcno IS NOT NULL
AND a.PERANT_POSITION_ID = (select g.POSITION_ID from xxkpc_fn_web_personnel_v g where g.kpcno = :kpcno)
GROUP BY b.KPCNO
,b.kpc_full_name
Please I need to combine these 2 queries into one query without using UNION
I think you can write it like:
select distinct b.kpcno, b.kpc_full_name
from xxxkpc_hr_personnel_v2 b
where b.type(+) = 'KPC Employee'
and b.kpcno is not null
and (
(b.designation is null and
b.organization_id in (select g.organization_id
from xxkpc_fn_web_personnel_v g
where g.kpcno = :kpcno))
or
(b.position_id in (select a.child_position_id
from xxkpc_hr_pos_struct_code_comb a
where a.parent_position_id = (select g.position_id
from xxkpc_fn_web_personnel_v g
where g.kpcno = :kpcno)))
)
as far as I see you are using the group by to make the result distinct, so I used the proper key word. And a and b are not left joined, because in the next where anded clause you are saying a.parent_position_id = .....
SELECT
b.KPCNO,
b.KPC_FULL_NAME
FROM
xxkpc_hr_personnel_v2 b
LEFT OUTER JOIN xxkpc_hr_pos_struct_code_comb a ON b.position_id = a.child_position_id
INNER JOIN xxkpc_fn_web_personnel_v g ON g.kpcno = :kpcno
WHERE
b.type = 'KPC Employee'
AND b.kpcno IS NOT NULL
AND ((b.DESIGNATION IS NULL AND g.ORGANIZATION_ID = b.ORGANIZATION_ID)
OR (a.PERANT_POSITION_ID = g.POSITION_ID))
Do you have anyway to join the two tables? It looks like you can join on b.KPCNO or b.KPC_FULL_NAME.
