MS Access Subquery - sql

The sql queries below need to be combined so that it further reduces the results. One of these will need to be a subquery. I am newbie with Access and am only getting errors. The end result should further filter the results to only show the encounters meeting all criteria in both of the querys. Both of these result in the correct result individually...any help you could provide would be greatly appreciated.
SELECT encounters.encounter_id, medications.encounter_id,
medications.medication_id, medication_types.medication_id,
medication_types.name, medication_types.class
FROM medication_types
INNER JOIN (encounters
INNER JOIN medications ON encounters.encounter_id = medications.encounter_id)
ON medication_types.medication_id = medications.medication_id
WHERE medication_types.class LIKE '*Antibiotic*';
SELECT encounters.encounter_id, encounters.admit_year,
diseases.encounter_id, diseases.disease_id,
disease_types.disease_id, disease_types.icd9cm
FROM encounters
INNER JOIN (disease_types
INNER JOIN diseases ON disease_types.disease_id = diseases.disease_id)
ON encounters.encounter_iD = diseases.encounter_id
WHERE disease_types.icd9cm IN ('041.3','480.0','480.1','480.2','480.3','480.8','480.9','481','482.1','482.2','482.9','486','V03.82','V12.61')
AND admit_week BETWEEN 5 and 9
AND encounters.admit_year = 2014
ORDER BY encounters.admit_week;

If you don't need to display the medications and diseases, just return the encounter info, consider:
SELECT DISTINCT encounters.encounter_id, admit_year FROM Query2 WHERE encounters.encounter_id IN (SELECT encounters.encounter_id FROM Query1);

Oracle SQL query that deals with inner Joins and values

SELECT sc.TAAC_SHARE_CLASS_ID,
SCS.SHARE_CLASS_SID,
SCS.REPORTING_DT,
SCS.SHARE_CLASS_SNAPSHOT_SID,
SCS.DIST_UNMOD_30_DAY_YIELD_PCT,
SCS.DER_DIST_12_MO_YIELD_PCT,
SCS.DER_SEC_30_DAY_YIELD_PCT AS SCS_DER_SEC_30_DAY_YIELD_PCT,
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;
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;

Access SQL query without duplicate results

I made a query and wanted to not have any duplicates but i got some times 3 duplicates and when i used DISTINCT or DISTINCTROW i got only 2 duplicates.
SELECT f.flight_code,
f.status,
a.airport_name,
a1.airport_name,
f.departing_date+f.departing_time AS SupposedDepartingTime,
f.landing_date+f.landing_time AS SupposedLandingTime,
de.actual_takeoff_date+de.actual_takeoff_time AS ActualDepartingTime,
SupposedLandingTime+(ActualDepartingTime-SupposedDepartingTime) AS ActualLandingTime
FROM
(((Flights AS f
LEFT JOIN Aireports AS a
ON a.airport_code = f.depart_ap)
LEFT JOIN Aireports AS a1
ON f.target_ap = a1.airport_code)
LEFT JOIN Irregular_Events AS ie
ON f.flight_code = ie.flight_code)
LEFT JOIN Delay_Event AS de
ON ie.IE_code = de.delay_code;
had to use LEFT JOIN because when i used INNER JOIN i missed some of the things i wanted to show because i wanted to see all the flights and not only the flights that got delayed or canceled.
This is the results when i used INNER JOIN, you can see only the flights that have the status "ביטול" or "עיכוב" and that is not what i wanted.
[the results with LEFT JOIN][2]
[2]: https://i.stack.imgur.com/cgE2G.png
and when i used DISTINCT where you see the rows with the NUMBER 6 on the first column it appear only two times
IMPORTANT!
I just checked my query and all the tables i use there and i saw my problem but dont know how to fix it!
in the table Irregular_Events i have more the one event for flights 3,6 and 8 and that is why when i use LEFT JOIN i see more even thou i use distinct, please give me some help!
Not entirely sure without seeing the table structure, but this might work:
SELECT f.flight_code,
f.status,
a.airport_name,
a1.airport_name,
f.departing_date+f.departing_time AS SupposedDepartingTime,
f.landing_date+f.landing_time AS SupposedLandingTime,
de.actual_takeoff_date+de.actual_takeoff_time AS ActualDepartingTime,
SupposedLandingTime+(ActualDepartingTime-SupposedDepartingTime) AS ActualLandingTime
FROM
((Flights AS f
LEFT JOIN Aireports AS a
ON a.airport_code = f.depart_ap)
LEFT JOIN Aireports AS a1
ON f.target_ap = a1.airport_code)
LEFT JOIN
(
SELECT
ie.flight_code,
de1.actual_takeoff_date,
de1.actual_takeoff_time
FROM
Irregular_Events ie
INNER JOIN Event AS de1
ON ie.IE_code = de1.delay_code
) AS de
ON f.flight_code = de.flight_code
It is hard to tell what is the problem with your query without any sample of the output, and without any description of the structure of your tables.
But your problem is that your are querying from the flights table, which [I assume] can be linked to multiple irregular_events, which can possibly also be linked to multiple delay_event.
If you want to get only one row per flight, you need to make sure your joins return only one row too. Maybe you can do it by adding one more condition to the join, or by adding a condition in a sub-query.
EDIT
You could try to add a GROUP BY to the query:
GROUP BY
f.flight_code,
f.status,
a.airport_name,
a1.airport_name;

COUNT is outputting more than one row

I am having a problem with my SQL query using the count function.
When I don't have an inner join, it counts 55 rows. When I add the inner join into my query, it adds a lot to it. It suddenly became 102 rows.
Here is my SQL Query:
SELECT COUNT([fmsStage].[dbo].[File].[FILENUMBER])
FROM [fmsStage].[dbo].[File]
INNER JOIN [fmsStage].[dbo].[Container]
ON [fmsStage].[dbo].[File].[FILENUMBER] = [fmsStage].[dbo].[Container].[FILENUMBER]
WHERE [fmsStage].[dbo].[File].[RELATIONCODE] = 'SHIP02'
AND [fmsStage].[dbo].[Container].DELIVERYDATE BETWEEN '2016-10-06' AND '2016-10-08'
GROUP BY [fmsStage].[dbo].[File].[FILENUMBER]
Also, I have to do TOP 1 at the SELECT statement because it returns 51 rows with random numbers inside of them. (They are probably not random, but I can't figure out what they are.)
What do I have to do to make it just count the rows from [fmsStage].[dbo].[file].[FILENUMBER]?
First, your query would be much clearer like this:
SELECT COUNT(f.[FILENUMBER])
FROM [fmsStage].[dbo].[File] f INNER JOIN
[fmsStage].[dbo].[Container] c
ON v.[FILENUMBER] = c.[FILENUMBER]
WHERE f.[RELATIONCODE] = 'SHIP02' AND
c.DELIVERYDATE BETWEEN '2016-10-06' AND '2016-10-08';
No GROUP BY is necessary. Otherwise you'll just one row per file number, which doesn't seem as useful as the overall count.
Note: You might want COUNT(DISTINCT f.[FILENUMBER]). Your question doesn't provide enough information to make a judgement.
Just remove GROUP BY Clause
SELECT COUNT([fmsStage].[dbo].[File].[FILENUMBER])
FROM [fmsStage].[dbo].[File]
INNER JOIN [fmsStage].[dbo].[Container]
ON [fmsStage].[dbo].[File].[FILENUMBER] = [fmsStage].[dbo].[Container].[FILENUMBER]
WHERE [fmsStage].[dbo].[File].[RELATIONCODE] = 'SHIP02'
AND [fmsStage].[dbo].[Container].DELIVERYDATE BETWEEN '2016-10-06' AND '2016-10-08'

MS Access SQL left join giving all 0

I am trying to make a summary table of all the items I have. I have a raw data table with 10 users who respectively have different items. There are maximum 3 different items and I want to do a count to see how many items each individual has. The following is my code.
Select b.Country,b.UserID,Num_including_fruits, Apple,Orange
from
(((SELECT o.Country,o.UserID, IIF(ISNULL(Count(o.UserID)),0,Count(o.UserID))
AS Num_including_fruits
FROM [SEA2_View] as o
GROUP BY o.UserID, o.Country
ORDER BY Country)as b
LEFT JOIN
(SELECT o.Country,o.UserID,IIF(ISNULL(Count(o.UserID)),0,Count(o.UserID)
AS Apple
FROM [APAC2_View] as o
WHERE o.fruit_status <>"fresh" AND o.HWType = "Apple"
GROUP BY o.Country,o.UserID)as d
ON (b.UserID = d.UserID))
LEFT JOIN
(SELECT o.Country,o.UserID,IIF(ISNULL(Count(o.UserID)),0,Count(o.UserID))
AS Orange
FROM [SEA2_View] as o
WHERE o.fruit_status <>"fresh" AND o.HWType = "Orange"
GROUP BY o.Country,o.UserID)as e
ON (d.UserID = e.UserID))
;
The first join returns the correct result but the second join somehow returns all 0, which is incorrect. Therefore please help! and I would appreciate any advice for best practice when it comes to joins in SQL. Thanks lot!
Are you sure you don't have a table naming error?
You're first joining [SEA2_View] with [APAC2_View]. The second join is joining with [SEA2_View] with itself.

SQL Query not working

I have these four tables:
SELECT [B_Key]
,[B_FiscalYear]
,[B_OrgCode]
,[B_SubObject]
,[B_Explanation]
,[B_CIPrefNo]
,[B_OrgBudgetAmt]
,[B_BudgetAmt]
,[B_Initials]
FROM [NAOLI].[dbo].[BudgetTbl]
SELECT [F_Fykey]
,[F_FiscalYear]
,[F_Year]
FROM [NAOLI].[dbo].[codeFiscalYearTbl]
SELECT [O_OrgKey]
,[O_OrgCode]
,[O_OrgDesc]
,[O_Divisions]
FROM [NAOLI].[dbo].[codeOrgCodeTbl]
SELECT [S_SubKey]
,[S_SubObject]
,[S_SubDescrip]
FROM [NAOLI].[dbo].[codeSubObjectTbl]
I need to combine different pieces of the information in these tables in order to make the table of information below:
[B_FiscalYear]
,[O_OrgCode]
,[O_OrgDesc]
,[S_SubObject]
,[S_SubDescrip]
,[B_BudgetAmt]
,[B_Initials]
,[B_CIPrefNo]
,[B_OrgBudgetAmt]
I tried the below query but it returns 0 of the 20750 records.. How do I accomplish this? thanks
SELECT [B_FiscalYear]
,[B_OrgCode]
,[O_OrgDesc]
,[B_SubObject]
,[S_SubDescrip]
,[B_BudgetAmt]
,[B_Initials]
,[B_CIPrefNo]
,[B_OrgBudgetAmt]
INTO dbo.BudgetsTbl
FROM [BudgetTbl] BT, [codeFiscalYearTbl] FY, [codeOrgCodeTbl] OC, [codeSubObjectTbl] SO
WHERE BT.B_FiscalYear = FY.F_Year and BT.B_OrgCode = OC.O_OrgCode and BT.B_SubObject = SO.S_SubObject
The join should be like this:
SELECT [B_FiscalYear]
,[B_OrgCode]
,[O_OrgDesc]
,[B_SubObject]
,[S_SubDescrip]
,[B_BudgetAmt]
,[B_Initials]
,[B_CIPrefNo]
,[B_OrgBudgetAmt]
FROM BudgetTbl BT
JOIN codeFiscalYearTbl FY ON BT.B_FiscalYear = FY.F_Year
JOIN codeOrgCodeTbl OC ON BT.B_OrgCode = OC.O_OrgCode
JOIN codeSubObjectTbl SO ON BT.B_SubObject = SO.S_SubObject
You can look at http://sqlfiddle.com/#!3/8ff6b/7 for more info.
Also you can add left joins if needed.
The proper join syntax is:
SELECT [B_FiscalYear], [B_OrgCode], [O_OrgDesc], [B_SubObject], [S_SubDescrip],
[B_BudgetAmt], [B_Initials], [B_CIPrefNo], [B_OrgBudgetAmt]
INTO dbo.BudgetsTbl
FROM BudgetTbl BT join
codeFiscalYearTbl FY
on BT.B_FiscalYear = FY.F_Year join
codeOrgCodeTbl OC
on BT.B_OrgCode = OC.O_OrgCode join
codeSubObjectTbl SO
on BT.B_SubObject = SO.S_SubObject
Presumably, one or more of your lookup tables are empty. If you want all rows, replace the "join" with "left outer join" in the above query.
