I have joined select columns from 3 tables into a new table using the following:
SELECT A.ExternalID, A.UserDefinedXml.value('(Skin_Sheet/#Label)[1]', 'varchar(3)') AS SS, A.ServiceSiteUid, A.LastModifiedDate, A.PersonUid,
B.FirstName, B.LastName, B.PersonUid,
C.Name
FROM Patient A
INNER JOIN Person B ON B.PersonUid = A.PersonUid
INNER JOIN ListServiceSite C ON C.ServiceSiteUid = A.ServiceSiteUid
WHERE SS IS NOT NULL
ORDER By LastModifiedDate;
This all works but I'm not sure how to reference the column SS created from data extracted from the XML so I can only select the observations in which the value is "Yes" or "No". In R I would have created a new object but I'm not sure how SQL stores this new table if I don't specify what the table name is.
Side note, I did try to insert this into a new table but SQL wasn't letting me because, for some reason, the join resulted in PersonUid being duplicated.
Thank you in advance, I'm very, very new to SQL and trying to learn on the fly.
Conceptually WHERE comes before SELECT, so you need to push the query into a derived table subquery or Common Table Expression (CTE) to reference SS in a WHERE clause. EG
with q as
(
SELECT A.ExternalID, A.UserDefinedXml.value('(Skin_Sheet/#Label)[1]', 'varchar(3)') AS SS, A.ServiceSiteUid, A.LastModifiedDate, A.PersonUid,
B.FirstName, B.LastName, B.PersonUid,
C.Name
FROM Patient A
INNER JOIN Person B ON B.PersonUid = A.PersonUid
INNER JOIN ListServiceSite C ON C.ServiceSiteUid = A.ServiceSiteUid
)
SELECT *
FROM q
WHERE SS IS NOT NULL
ORDER By LastModifiedDate;
This will put your results into a temp table, and avoids the problem of having two columns with the same name:
SELECT
A.ExternalID
,SS = A.UserDefinedXml.value('(Skin_Sheet/#Label)[1]', 'varchar(3)')
,A.ServiceSiteUid
,A.LastModifiedDate
,PersonUid_A = A.PersonUid
,B.FirstName
,B.LastName
,PersonUid_B = B.PersonUid
,C.Name
INTO #TempResults
FROM Patient A
INNER JOIN Person B ON B.PersonUid = A.PersonUid
INNER JOIN ListServiceSite C ON C.ServiceSiteUid = A.ServiceSiteUid
WHERE SS IS NOT NULL
ORDER BY LastModifiedDate;

I have 3 tables in that 2 tables are master table and 3rd is transaction table. i need to get count from transaction table for each value in other two table without loosing rows in mater table
i need result like below
Table layout for understanding
This is the code i have tried,
select s.status_name, e.machine_group_name, qty = COALESCE(COUNT(e.id),0)
from tbl_status s
left outer JOIN tbl_transaction as e ON e.status_name = s.status_name
group by e.machine_group_name, s.status_name
This is solution i have figured:
select m.machine_group_name, s.status_name, qty = COUNT(e.id) from
tbl_machine_group as m
cross join tbl_status as s
left outer join tbl_transaction as e on e.status_name = s.status_name
and e.machine_group_name = m.machine_group_name
group by m.machine_group_name, s.status_name
order by machine_group_name
select
MC_Group_Name
,Status_Name
,count(1) as [Count of Transaction]
from
tbl_Transaction tbl_3
left join tbl_Machine_Group tbl_1
on tbl_3.MC_Group_Name = tbl_1.MC_Group_Name
left join tbl_Status tbl_2
on tbl_3.Status_Name = tbl_2.Status_Name
group by
MC_Group_Name
,Status_Name
I wrote the below query to pull the data from different databases. I have created two temp tables to pull the data from two different databases and finally a select statement from the original database to join all the tables. My query is getting executed but not getting any data.(Report is blank). I tried executing the two temp tables separately. it is giving the correct data. But when I execute the whole query, the result is blank. Below is the query. Please help.

IF the data in each temp table is verified, then:
Try a smaller, less complex, query to test your temp tables with. Also try them using a LEFT join as well e.g.:
select
c.RtlrContractIdentifier as ContractID
, c.SigningDate
, datediff(day, getdate(), c.RenewalDate) as RemainingDays
, c.RenewalDate
, l.ContractCallLogStatusIdentifier as CallLogType
, Substring (l.Description, 1, 20) as CallPurpose
, l.db_insertDate as CallLogDate
, cms.CampaignOfferOID as OfferID
, cms.CampaignContractStatusIdentifier as OfferStatus
, cms.CampaignContractStatusUpdateDate as StatusChangeDate
, cms.DeclineDate
from Contract c
LEFT join #CISIS_Call_Log l on convert(varchar(15), l.ContractOID) = c.RtlrContractIdentifier
LEFT join #CMS_Campaign cms on convert(varchar(15), cms.ContractOID) = c.RtlrContractIdentifier
Does this return data? Does it return data from both joined tables?
If neither temp table is returning data then those join conditions need to be changed.
If both temp tables do return data from that query, then try INNER joins. If that still works, then add back more joins (one at a time) until you identify the join that causes the overall fault.
Without data for every table it just isn't possible for us to pinpoint the exact reason for a NULL result. Only you can, so you need to trouble-shoot the problem one step at a time.

ON KPI.kpilib_code = Z.kpilib_code
LEFT JOIN TPMDPERIODKPI PK

This is my code.
I could run it in SQL Server,
But now i have to use Mariadb,
and Mariadb doesn't use "WITH AS".
So is there any other way to change this code for the same result?
As we can see, there's "INNER JOIN KPILibHier" too inside the CTE,
So I couldn't make ordinary subquery as usual.
Just moving the contents of the CTE to a derived table should provide something usable. Something like;
SELECT DISTINCT Z.kpi_name AS libname, Z.kpilib_code AS libcode,
Z.parent_code AS pcode, Z.depth, Z.iscategory, PK.target
FROM
( SELECT K.kpilib_code, K.parent_code, K.kpi_name_en AS kpi_name, K.kpi_depth AS depth, K.iscategory
FROM TPMDPERIODKPILIB K
INNER JOIN TPMDPERIODKPI PK ON PK.period_code = K.period_code
UNION ALL
SELECT A.kpilib_code, A.parent_code, A.kpi_name_en, A.kpi_depth, A.iscategory
FROM TPMDPERIODKPILIB A
) z
INNER JOIN z AS B ON A.kpilib_code = B.parent_code
LEFT JOIN TPMDPERIODKPILIB KPI
ON KPI.kpilib_code = Z.kpilib_code
LEFT JOIN TPMDPERIODKPI PK
ON PK.period_code = KPI.period_code
ORDER BY Z.depth, Z.kpi_name
I have an existing proc which I have chopped up for brevity's sake
SELECT col1, col2
FROM (
col1, col2
SELECT col3--aggregate columns
FROM iep i
INNER JOIN student s ON s.studentID = i.studentID
INNER JOIN dbo.IDuration id ON i.IepID = id.iepID
INNER JOIN AppointmentStudent as ON s.studentID = as.studentID
INNER JOIN Appointment a ON as.appointmentID = a.appointmentID
INNER JOIN AppointmentTherapist at ON a.appointmentID = at.appointmentID
WHERE s.studentID = #studentID
GROUP BY col1, col2
) t
The aggregate columns summarizes appointments into the weeks of the year, but it only does sos for the weeks the student had appointments. I have an additional table called SchoolWeekYear that is populated with all of the weeks of the year that I am trying to integrate to this proc so I get 52 records back and not just the handful I am currently getting.
SELECT col1, col2
FROM (
col1, col2
SELECT col3--aggregate columns
FROM iep i
INNER JOIN student s ON s.studentID = i.studentID
INNER JOIN dbo.IDuration id ON i.IepID = id.iepID
INNER JOIN AppointmentStudent as ON s.studentID = as.studentID
INNER JOIN Appointment a ON as.appointmentID = a.appointmentID
LEFT OUTER JOIN SchoolWeekYear swy on a.calWeekNumber = swy.calWeekNumber
INNER JOIN AppointmentTherapist at ON a.appointmentID = at.appointmentID
WHERE s.studentID = #studentID
GROUP BY col1, col2
) t
Is this possible?
You need to integrate SchoolWeekYear into the existing table set at an earlier stage.
To show you the principle, let us simplify the problem even further. Let there be a table called WeeklyData with columns WeekNumber and SomeData. Some weeks might have multiple entries, some others none. So this query
SELECT
WeekNumber,
AGG(SomeData)
FROM
WeeklyData
GROUP BY
WeekNumber
;
would return only weeks present in WeeklyData. If you want to return data for all weeks, use a corresponding reference table (let it be called AllWeeks) like this:
SELECT
aw.WeekNumber,
AGG(wd.SomeData)
FROM
AllWeeks AS aw
LEFT JOIN
WeeklyData AS wd ON aw.WeekNumber = wd.WeekNumber
GROUP BY
aw.WeekNumber
;
So, you take the reference table (AllWeeks) and join the data table (WeeklyData) to it, not the other round.
Now, what if the original query was slightly more complex? Let us now suppose the data table is called StudentWeeklyData and has a column called StudentID which is a reference to a Students table. Let us also imagine the query is similar to yours in that it logically includes the Students table before the data table is joined and filters the results on the primary key of Students:
SELECT
s.StudentID,
s.StudentName,
swd.WeekNumber,
AGG(swd.SomeData)
FROM
Students AS s
INNER JOIN
StudentWeeklyData AS swd ON s.StudentID = swd.StudentID
WHERE
s.StudentID = #StudentID
GROUP BY
s.StudentID,
s.StudentName,
swd.WeekNumber
;
(Not every detail matters here, I just wanted to use a more similar example for you that would still be simple enough to understand.) Again, this would return only weeks where the specified student has data in StudentWeeklyTable. If you wanted to return all weeks for the student (some of them potentially empty, of course), this is how you could go about it:
SELECT
s.StudentID,
s.StudentName,
aw.WeekNumber,
AGG(swd.SomeData)
FROM
Students AS s
CROSS JOIN
AllWeeks AS aw
LEFT JOIN
StudentWeeklyData AS swd ON s.StudentID = swd.StudentID
AND aw.WeekNumber = swd.WeekNumber
WHERE
s.StudentID = #StudentID
GROUP BY
s.StudentID,
s.StudentName,
aw.WeekNumber
;
Here you can see again that the AllWeeks table is included before the data table. The difference to the previous case is we are not left-joining the result of the join between Students and StudentWeekly to AllWeeks, nor are we left-joining the data table itself specifically to AllWeeks. Instead, the data table is joined to the result of a cross join, Students × AllWeeks.
Returning to your specific situation, I realise that in your case even more tables are involved. Since you are not specifying how all those tables are related to one another, I can only guess that SchoolWeekYear should be cross-joined somewhere after FROM and before this line:
INNER JOIN Appointment a ON as.appointmentID = a.appointmentID
and that the said line should be modified like this:
LEFT JOIN Appointment a ON as.appointmentID = a.appointmentID
AND swy.calWeekNumber = a.calWeekNumber
the swy being an alias assigned to SchoolWeekYear.
It is also worth noting that there is a subsequent inner join with AppointmentTherapist. That join would eliminate the effect of the above left join if it remained unchanged, because its condition references the Appointment table. Perhaps, the syntactically easiest way to fix the issue would be to change that inner join to a left one too, although there is another way: instead of
LEFT JOIN Appointment a ON as.appointmentID = a.appointmentID
AND swy.calWeekNumber = a.calWeekNumber
LEFT JOIN AppointmentTherapist at ON a.appointmentID = at.appointmentID
you could use this syntax:
LEFT JOIN
Appointment a
INNER JOIN AppointmentTherapist at ON a.appointmentID = at.appointmentID
ON as.appointmentID = a.appointmentID
AND swy.calWeekNumber = a.calWeekNumber
That way the logical order of joining would be changed: Appointment and AppointmentTherapist would be first inner-joined with each other, then the result set would be outer-joined to the result of the previously specified joins.
It is possible. But if you have multiple row with some calWeekNumber on the SchoolWeekYear table, your aggregate function return wrong result.
If you want all lines in SchoolWeekYear shown, regardless of a match, you should use RIGHT OUTER JOIN instead of LEFT.
I need to select a random record from 3 tables and ensure I am ordering by photoOrder
Select TOP 1(a.id), a.mls_number, a.parcel_name, a.property_type, a.ownership_type, b.filename, b.photoOrder, c.county_Name
From property as a
Inner JOIN
listingPhotos as b on a.id = b.ListingID
LEFT JOIN
counties as C on a.county_name = c.id
WHERE a.isCommercial = 'True'
Order By NEWID()
So this query works, but I need to ensure that the b.filename record is ordered by b.photoOrder and thus the b.photoOrder should always be 1.
The b table (listing photos) has multiple photo files per property and I need to only select the photo that is 1st in the photo order.
Thanks
You could subquery your listingPhotos table and limit to WHERE PhotoOrder = 1:
Select TOP 1(a.id), a.mls_number, a.parcel_name, a.property_type, a.ownership_type, b.filename, b.photoOrder, c.county_Name
From property as a
Inner JOIN
(SELECT ListingID , filename, PhotoOrder FROM listingPhotos WHERE PhotoORder = 1
) as b on a.id = b.ListingID
LEFT JOIN
counties as C on a.county_name = c.id
WHERE a.isCommercial = 'True'
Order By NEWID()
