Using report builder 3.0 for sql server 08 R2. Trying to get the most recent dates from 2 different columns in 2 different tables but I'm getting 4 rows instead of 1. In the picture below, there should be one row per patient.
Script I'm using is this:
SELECT "Patient"."PatientID", "PatientLastName", "PatientFirstName", "DischargeDate", "PatVisitPayable"."ContactDate"
FROM "BTI"."Patient"
JOIN "BTI"."PatAdmissions" ON "Patient"."PatientID" = "PatAdmissions"."PatientID"
JOIN "BTI"."PatVisitPayable" ON "PatAdmissions"."PatientID" = "PatVisitPayable"."PatientID"
JOIN "BTI"."PatAdmissionDivision" ON "PatAdmissions"."AdmissionID" = "PatAdmissionDivision"."AdmissionID"
GROUP BY "Patient"."PatientID", "PatientLastName", "PatientFirstName", "DischargeDate", "ContactDate"
I've tried putting max(contactdate) and max(dischargedate) in the select statement but still get 4 rows. Wasn't sure if this is something I should include in the initial query or something I can add to the report afterwards.
4 rows for one patient
Try to remove ContactDate from GROUP BY clause and use max() function in SELECT :
SELECT pt.PatientID,
pt.PatientLastName, pt.PatientFirstName, pt.DischargeDate,
MAX(ContactDate) as ContactDate
FROM BTI.Patient pt
JOIN BTI.PatAdmissions pa ON pt.PatientID = pa.PatientID
JOIN BTI.PatVisitPayable py ON pa.PatientID = py.PatientID
JOIN BTI.PatAdmissionDivision pd ON pa.AdmissionID = pd.AdmissionID
GROUP BY pt.PatientID, pt.PatientLastName,
pt.PatientFirstName, pt.DischargeDate;
Always define table alise that could be easy to follow/read and write.
This assumes ContactDate in resonbale format.

SELECT sc.TAAC_SHARE_CLASS_ID,

INNER JOIN SHARE_CLASS_SNAPSHOT SCS ON

WHERE SCS.REPORTING_DT = '24-JUL-17' AND P.PORTFOLIO_ID = 638;
I ran this query and got the following output : image
Here, instead of getting separate rows for the same TAAC_SHARE_CLASS_ID, I want to merge the outputs of same TAAC_SHARE_CLASS_ID.
For example, the first row with TAAC_SHARE_CLASS_ID = 000648 should have values for all the 4 columns :
SCS.DIST_UNMOD_30_DAY_YIELD_PCT,
SCS.DER_DIST_12_MO_YIELD_PCT,
SCS.DER_SEC_30_DAY_YIELD_PCT,
SCS.DER_SEC_RESTATED_YIELD_PCT.
Hence the first row should have values for those columns as 2.96,3.2972596, 7541.085263433, 7550.
The last 4 rows of my output are not really required, as we have now merged those data into first 4 rows correspondingly.
How can I alter this query to achieve the same? Please help.
I suggest you group your results by TAAC_SHARE_CLASS_ID column, and MAX() the remaining columns, something like this:
SELECT sc.TAAC_SHARE_CLASS_ID,
max(SCS.SHARE_CLASS_SID) as SHARE_CLASS_SID,
max(SCS.REPORTING_DT) as REPORTING_DT,
max(SCS.SHARE_CLASS_SNAPSHOT_SID) as SHARE_CLASS_SNAPSHOT_SID,
max(SCS.DIST_UNMOD_30_DAY_YIELD_PCT) as DIST_UNMOD_30_DAY_YIELD_PCT,
max(SCS.DER_DIST_12_MO_YIELD_PCT) as DER_DIST_12_MO_YIELD_PCT,
max(SCS.DER_SEC_30_DAY_YIELD_PCT) AS SCS_DER_SEC_30_DAY_YIELD_PCT,
max(SCS.DER_SEC_RESTATED_YIELD_PCT) AS SCS_DER_SEC_RESTATED_YIELD_PCT
FROM SHARE_CLASS sc
INNER JOIN PORTFOLIO P ON (P.PORTFOLIO_SID=SC.PORTFOLIO_SID)
INNER JOIN SHARE_CLASS_SNAPSHOT SCS ON (SCS.SHARE_CLASS_SID=sc.SHARE_CLASS_SID)
WHERE SCS.REPORTING_DT = '24-JUL-17' AND P.PORTFOLIO_ID = 638
GROUP BY sc.TAAC_SHARE_CLASS_ID;
I pop into a problem recently, and Im sure its because of how I Join them.
this is my code:
select LP_Pending_Info.Service_Order,
LP_Pending_Info.Pending_Days,
LP_Pending_Info.Service_Type,
LP_Pending_Info.ASC_Code,
LP_Pending_Info.Model,
LP_Pending_Info.IN_OUT_WTY,
LP_Part_Codes.PartCode,
LP_PS_Codes.PS,
LP_Confirmation_Codes.SO_NO,
LP_Pending_Info.Engineer_Code
from LP_Pending_Info
join LP_Part_Codes
on LP_Pending_Info.Service_order = LP_Part_Codes.Service_order
join LP_PS_Codes
on LP_Pending_Info.Service_Order = LP_PS_Codes.Service_Order
join LP_Confirmation_Codes
on LP_Pending_Info.Service_Order = LP_Confirmation_Codes.Service_Order
order by LP_Pending_Info.Service_order, LP_Part_Codes.PartCode;
For every service order I have 5 part code maximum.
If the service order have only one value it show the result correctly but when it have more than one Part code the problem begin.
for example: this service order"4182134076" has only 2 part code, first'GH81-13601A' and second 'GH96-09938A' so it should show the data 2 time but it repeat it for 8 time. what seems to be the problem?
If your records were exactly the same the distinct keyword would have solved it.
However in rows 2 and 3 which have the same Service_Order and Part_Code if you check the SO_NO you see it is different - that is why distinct won't work here - the rows are not identical.
I say you have some problem in one of the conditions in your joins. The different data is in the SO_NO column so check the raw data in the LP_Confirmation_Codes table for that Service_Order:
select * from LP_Confirmation_Codes where Service_Order = 4182134076
I assume you are missing an and with the value from the LP_Part_Codes or LP_PS_Codes (but can't be sure without seeing those tables and data myself).
By this sentence If the service order have only one value it show the result correctly but when it have more than one Part code the problem begin. - probably you are missing and and with the LP_Part_Codes table
Based on your output result, here are the following data that caused multiple output.
Service Order: 4182134076 has :
2 PartCode which are GH81-13601A and GH96-09938A
2 PS which are U and P
2 SO_NO which are 1.00024e+09 and 1.00022e+09
Therefore 2^3 returns 8 rows. I believe that you need to check where you should join your tables.
Use DINTINCT
select distinct LP_Pending_Info.Service_Order,LP_Pending_Info.Pending_Days,
LP_Pending_Info.Service_Type,LP_Pending_Info.ASC_Code,LP_Pending_Info.Model,
LP_Pending_Info.IN_OUT_WTY, LP_Part_Codes.PartCode,LP_PS_Codes.PS,
LP_Confirmation_Codes.SO_NO,LP_Pending_Info.Engineer_Code
from LP_Pending_Info
join LP_Part_Codes on LP_Pending_Info.Service_order = LP_Part_Codes.Service_order
join LP_PS_Codes on LP_Part_Codes.Service_Order = LP_PS_Codes.Service_Order
join LP_Confirmation_Codes on LP_PS_Codes.Service_Order = LP_Confirmation_Codes.Service_Order
order by LP_Pending_Info.Service_order, LP_Part_Codes.PartCode;
distinct will not return duplicates based on your select. So if a row is same, it will only return once.
My title is probably not very clear, so I made a little schema to explain what I'm trying to achieve. The xxxx_uid labels are foreign keys linking two tables.
Goal: Retrieve a column from the grids table by giving a proj_uid value.
I'm not very good with SQL joins and I don't know how to build a single query that will achieve that.
Actually, I'm doing 3 queries to perform the operation:
1) This gives me a res_uid to work with:
select res_uid from results where results.proj_uid = VALUE order by res_uid asc limit 1"
2) This gives me a rec_uid to work with:
select rec_uid from receptor_results
inner join results on results.res_uid = receptor_results.res_uid
where receptor_results.res_uid = res_uid_VALUE order by rec_uid asc limit 1
3) Get the grid column I want from the grids table:
select grid_name from grids
inner join receptors on receptors.grid_uid = grids.grid_uid
where receptors.rec_uid = rec_uid_VALUE;
Is it possible to perform a single SQL that will give me the same results the 3 I'm actually doing ?
You're not limited to one JOIN in a query:
select grids.grid_name
from grids
inner join receptors
on receptors.grid_uid = grids.grid_uid
inner join receptor_results
on receptor_results.rec_uid = receptors.rec_uid
inner join results
on results.res_uid = receptor_results.res_uid
where results.proj_uid = VALUE;
select g.grid_name
from results r
join resceptor_results rr on r.res_uid = rr.res_uid
join receptors rec on rec.rec_uid = rr.rec_uid
join grids g on g.grid_uid = rec.grid_uid
where r.proj_uid = VALUE
a small note about names, typically in sql the table is named for a single item not the group. thus "result" not "results" and "receptor" not "receptors" etc. As you work with sql this will make sense and names like you have will seem strange. Also, one less character to type!
I am querying two tables:
tblPurhcaseOrders - holds purchase orders with various columns, one of which is a foreign key called OrderTypeID
tblOrderTypes - holds 4 types of purchase orders
One of the order types in tblOrderTypes was added later than the first 3 basic ones. Thus, instances of purchase orders with this newer order type appear only from a certain point of time (Feb. 2012).
I'm writing an aggregated query which should ultimately bring me the sum of all purchase orders, grouped by their type.
I do want the results to me 0 or NULL, even if I query a point of time in which the newer order type had not existed yet.
Here's how my query looks like:
SELECT
MONTH(tblPurchaseOrders.DeliveryDate) AS sMonth,
YEAR(tblPurchaseOrders.DeliveryDate) AS sYear,
tblOrderType.OrderTypeName,
SUM(ISNULL(TotalPrice,0)) AS sValue
FROM
tblPurchaseOrders
RIGHT OUTER JOIN
tblOrderTypes ON tblPurchaseOrders.OrderTypeID = tblOrderTypes.OrderTypeID
WHERE
MONTH(DeliveryDate) = 1
AND YEAR(DeliveryDate) = 2012
GROUP BY
MONTH(DeliveryDate), YEAR(DeliveryDate), tblOrderType.OrderTypeName
Now, the query above works just fine and provides me with correct aggregation, only it leaves out the newer order type (reminder, it didn't exist in JAN-2012 yet).
If I change the query condition to MONTH(DeliveryDate) = 2 AND YEAR(DeliveryDate) = 2012 it appears.
I've tried full join and also tried switching between the order of the two tables and toggled to LEFT OUTER JOIN, no luck.
Change
WHERE
MONTH(DeliveryDate) = 1
AND YEAR(DeliveryDate) = 2012
into
AND
MONTH(DeliveryDate) = 1
AND YEAR(DeliveryDate) = 2012
Need help on a query using sql server 2005
I am having two tables
code
chargecode
chargeid
orgid
entry
chargeid
itemNo
rate
I need to list all the chargeids in entry table if it contains multiple entries having different chargeids
which got listed in code table having the same charge code.
data :
code
100,1,100
100,2,100
100,3,100
101,11,100
101,12,100
entry
1,x1,1
1,x2,2
2,x3,2
11,x4,1
11,x5,1
using the above data , it query should list chargeids 1 and 2 and not 11.
I got the way to know how many rows in entry satisfies the criteria, but m failing to get the chargeids
select count (distinct chargeId)
from entry where chargeid in (select chargeid from code where chargecode = (SELECT A.chargecode
from code as A join code as B
ON A.chargecode = B.chargeCode and A.chargetype = B.chargetype and A.orgId = B.orgId AND A.CHARGEID = b.CHARGEid
group by A.chargecode,A.orgid
having count(A.chargecode) > 1)
)
First off: I apologise for my completely inaccurate original answer.
The solution to your problem is a self-join. Self-joins are used when you want to select more than one row from the same table. In our case we want to select two charge IDs that have the same charge code:
SELECT DISTINCT c1.chargeid, c2.chargeid FROM code c1
JOIN code c2 ON c1.chargeid != c2.chargeid AND c1.chargecode = c2.chargecode
JOIN entry e1 ON e1.chargeid = c1.chargeid
JOIN entry e2 ON e2.chargeid = c2.chargeid
WHERE c1.chargeid < c2.chargeid
Explanation of this:
First we pick any two charge IDs from 'code'. The DISTINCT avoids duplicates. We make sure they're two different IDs and that they map to the same chargecode.
Then we join on 'entry' (twice) to make sure they both appear in the entry table.
This approach gives (for your example) the pairs (1,2) and (2,1). So we also insist on an ordering; this cuts to result set down to just (1,2), as you described.
