I have the following data in table VehiclesAccSummary:
I am not sure how to do this but what I want is a query that would return all rows where there where only two car in the accident and it was a head on crash so in both cars PointOfImpact was 'Front' i know in need to do some inner join on the same table but i don' want to join same car with it self. Any idea ?
The end result should be something like this
You can use a subquery to count the number of "Front' records for each AccRef.
SELECT *
FROM VehiclesAccSummary INNER JOIN
(SELECT VehiclesAccSummary.AccRef, Count(VehiclesAccSummary.PointOfImpact) AS CountOfPointOfImpact FROM VehiclesAccSummary GROUP BY VehiclesAccSummary.AccRef, VehiclesAccSummary.PointOfImpact HAVING VehiclesAccSummary.PointOfImpact="Front") AS FrontCount
ON VehiclesAccSummary.AccRef = FrontCount.AccRef
WHERE VehiclesAccSummary.NumCars = 2 AND CountOfPointOfImpact = 2;
This will limit the records to AccRefs with NumCar = 2 and the count of Front records = 2.
Edit: Since the same car can be listed in multiple records, we need a new approach. Try this:
SELECT VehiclesAccSummary.*, Subquery.CountOfPointOfImpact
FROM VehiclesAccSummary LEFT JOIN (SELECT VehiclesAccSummary.AccRef, Count(VehiclesAccSummary.PointOfImpact) AS CountOfPointOfImpact
FROM VehiclesAccSummary
WHERE (((VehiclesAccSummary.PointOfImpact)<>"Front"))
GROUP BY VehiclesAccSummary.AccRef) AS Subquery ON VehiclesAccSummary.AccRef = Subquery.AccRef
WHERE (((Subquery.CountOfPointOfImpact) Is Null));
Instead of confirming that the count of front accidents is 2, this confirms that the count of non-front accidents is 0.

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'
I have one SQL statement as:
SELECT ARTICLES.NEWS_ARTCL_ID, ARTICLES.NEWS_ARTCL_TTL_DES,
ARTICLES.NEWS_ARTCL_CNTNT_T, ARTICLES.NEWS_ARTCL_PUB_DT,
ARTICLES.NEWS_ARTCL_AUTH_NM, ARTICLES.NEWS_ARTCL_URL, ARTICLES.MEDIA_URL,
ARTICLES.ARTCL_SRC_ID, SOURCES.ARTCL_SRC_NM, MEDIA.MEDIA_TYPE_DESCRIP
FROM
RSKLMOBILEB2E.NEWS_ARTICLE ARTICLES,
RSKLMOBILEB2E.MEDIA_TYPE MEDIA,
RSKLMOBILEB2E.ARTICLE_SOURCE SOURCES
WHERE ARTICLES.MEDIA_TYPE_IDENTIF = MEDIA.MEDIA_TYPE_IDENTIF
AND ARTICLES.ARTCL_SRC_ID = SOURCES.ARTCL_SRC_ID
AND ARTICLES.ARTCL_SRC_ID = 1
ORDER BY ARTICLES.NEWS_ARTCL_PUB_DT
Now I need to combine another SQL statement into one which is:
SELECT COUNT ( * )
FROM RSKLMOBILEB2E.NEWS_LIKES LIKES, RSKLMOBILEB2E.NEWS_ARTICLE ARTICLES
WHERE LIKES.NEWS_ARTCL_ID = ARTICLES.NEWS_ARTCL_ID
Basically I have one table which contains articles and I need to include the user likes which is in another table.
Use a subquery to add the likescount in your first query like this:
SELECT ARTICLES.NEWS_ARTCL_ID
,ARTICLES.NEWS_ARTCL_TTL_DES
,ARTICLES.NEWS_ARTCL_CNTNT_T
,ARTICLES.NEWS_ARTCL_PUB_DT
,ARTICLES.NEWS_ARTCL_AUTH_NM
,ARTICLES.NEWS_ARTCL_URL
,ARTICLES.MEDIA_URL
,ARTICLES.ARTCL_SRC_ID
,SOURCES.ARTCL_SRC_NM
,MEDIA.MEDIA_TYPE_DESCRIP
,(
SELECT COUNT(*)
FROM RSKLMOBILEB2E.NEWS_LIKES LIKES
WHERE LIKES.NEWS_ARTCL_ID = ARTICLES.NEWS_ARTCL_ID
) AS LikesCount
FROM RSKLMOBILEB2E.NEWS_ARTICLE ARTICLES
,RSKLMOBILEB2E.MEDIA_TYPE MEDIA
,RSKLMOBILEB2E.ARTICLE_SOURCE SOURCES
WHERE ARTICLES.MEDIA_TYPE_IDENTIF = MEDIA.MEDIA_TYPE_IDENTIF
AND ARTICLES.ARTCL_SRC_ID = SOURCES.ARTCL_SRC_ID
AND ARTICLES.ARTCL_SRC_ID = 1
ORDER BY ARTICLES.NEWS_ARTCL_PUB_DT;
I'm not sure what you are trying to achieve but it seems you want to count all the data from 2 tables. You can edit your query to something like this.
SELECT COUNT (ARTICLES.*) FROM RSKLMOBILEB2E.NEWS_LIKES LIKES
JOIN RSKLMOBILEB2E.NEWS_ARTICLE ARTICLES
ON LIKES.NEWS_ARTCL_ID = ARTICLES.NEWS_ARTCL_ID
I think that solution is in using Analytic Functions. Please have a look on https://oracle-base.com/articles/misc/analytic-functions
Please check following query (keep in mind I have no idea about your table structures). Due to left join records might be duplicated, this is why grouping is added.
SELECT ARTICLES.NEWS_ARTCL_ID, ARTICLES.NEWS_ARTCL_TTL_DES,
ARTICLES.NEWS_ARTCL_CNTNT_T, ARTICLES.NEWS_ARTCL_PUB_DT,
ARTICLES.NEWS_ARTCL_AUTH_NM, ARTICLES.NEWS_ARTCL_URL, ARTICLES.MEDIA_URL,
ARTICLES.ARTCL_SRC_ID, SOURCES.ARTCL_SRC_NM, MEDIA.MEDIA_TYPE_DESCRIP,
count(LIKES.ID) over ( partition by ARTICLES.NEWS_ARTCL_ID ) as num_likes
FROM RSKLMOBILEB2E.NEWS_ARTICLE ARTICLES
join RSKLMOBILEB2E.MEDIA_TYPE MEDIA
on ARTICLES.MEDIA_TYPE_IDENTIF = MEDIA.MEDIA_TYPE_IDENTIF
join RSKLMOBILEB2E.ARTICLE_SOURCE SOURCES
on ARTICLES.ARTCL_SRC_ID = SOURCES.ARTCL_SRC_ID
LEFT JOIN RSKLMOBILEB2E.NEWS_LIKES LIKES
ON LIKES.NEWS_ARTCL_ID = ARTICLES.NEWS_ARTCL_ID
WHERE
ARTICLES.ARTCL_SRC_ID = 1
group by ARTICLES.NEWS_ARTCL_ID, ARTICLES.NEWS_ARTCL_TTL_DES,
ARTICLES.NEWS_ARTCL_CNTNT_T, ARTICLES.NEWS_ARTCL_PUB_DT,
ARTICLES.NEWS_ARTCL_AUTH_NM, ARTICLES.NEWS_ARTCL_URL, ARTICLES.MEDIA_URL,
ARTICLES.ARTCL_SRC_ID, SOURCES.ARTCL_SRC_NM, MEDIA.MEDIA_TYPE_DESCRIP
ORDER BY ARTICLES.NEWS_ARTCL_PUB_DT
I also changed coma-separated list of tables from where condition to joins. I think this is more readable since table join conditions are separated from result filtering in where clause.
I've got a query running that pulls out the records I need.
I want to run another query that pulls out all the other records (excluding the ones in the first query).
I've read up on NOT IN and NOT LIKE but can't seem to get them to work.
The first query is named: qryHunnersPatients
Here's the code for the second query that I have so far:
Right now this is just pulling all the records - but I want to exclude those records in the qryHunnersPatients query
SELECT
tblPatientHistoryBaseline.ID,
tblPatientHistoryBaseline.Age,
[tblPatientHistoryBaseline].[Age]-[tblPatientHistoryBaseline].[UrinarySxBegan] AS Duration,
tblPatientHistoryBaseline.IBS,
tblQuestionnaires.UPOINTTotal,
tblQuestionnaires.U,
tblQuestionnaires.P,
tblQuestionnaires.O,
tblQuestionnaires.I,
tblQuestionnaires.N,
tblQuestionnaires.T,
tblQuestionnaires.ICSITotal,
tblQuestionnaires.ICPITotal
FROM
tblPatientHistoryBaseline
INNER JOIN
tblQuestionnaires
ON
(tblPatientHistoryBaseline.Visit = tblQuestionnaires.Visit)
AND
(tblPatientHistoryBaseline.ID = tblQuestionnaires.ID);
UPDATE:
I just tried the WHERE NOT EXISTS using the code below:
SELECT
tblPatientHistoryBaseline.ID,
tblPatientHistoryBaseline.Age,
[tblPatientHistoryBaseline].[Age]-[tblPatientHistoryBaseline].[UrinarySxBegan] AS Duration,
tblPatientHistoryBaseline.IBS,
tblQuestionnaires.UPOINTTotal,
tblQuestionnaires.U,
tblQuestionnaires.P,
tblQuestionnaires.O,
tblQuestionnaires.I,
tblQuestionnaires.N,
tblQuestionnaires.T,
tblQuestionnaires.ICSITotal,
tblQuestionnaires.ICPITotal
FROM
tblPatientHistoryBaseline
INNER JOIN
tblQuestionnaires
ON
(tblPatientHistoryBaseline.Visit = tblQuestionnaires.Visit)
AND
(tblPatientHistoryBaseline.ID = tblQuestionnaires.ID)
WHERE NOT EXISTS
(SELECT ID
FROM qryHunnersPatients AS hunners
WHERE hunners.ID = tblPatientHistoryBaseline.ID);
You need a SubQuery. As In understand that your Query qryHunnersPatients gives you the list of records that you do not wish to see, you need to include that in the NOT IN part of the Query.
SELECT
tblPatientHistoryBaseline.ID,
tblPatientHistoryBaseline.Age,
[tblPatientHistoryBaseline].[Age]-[tblPatientHistoryBaseline].[UrinarySxBegan] AS Duration,
tblPatientHistoryBaseline.IBS,
tblQuestionnaires.UPOINTTotal,
tblQuestionnaires.U,
tblQuestionnaires.P,
tblQuestionnaires.O,
tblQuestionnaires.I,
tblQuestionnaires.N,
tblQuestionnaires.T,
tblQuestionnaires.ICSITotal,
tblQuestionnaires.ICPITotal
FROM
tblPatientHistoryBaseline
INNER JOIN
tblQuestionnaires
ON
(tblPatientHistoryBaseline.Visit = tblQuestionnaires.Visit)
AND
(tblPatientHistoryBaseline.ID = tblQuestionnaires.ID)
WHERE
tblPatientHistoryBaseline.ID
NOT IN
(SELECT qryHunnersPatients.ID FROM qryHunnersPatients);
Assuming ID is unique, you can use WHERE NOT EXISTS:
SELECT {FieldList}
FROM tblPatientHistoryBaseline AS baseline
INNER JOIN tblQuestionnaires AS quest
ON (baseline.Visit = quest.Visit)
AND (baseline.ID = quest.ID);
WHERE NOT EXISTS (
SELECT ID
FROM qryHunnersPatients AS hunners
WHERE hunners.ID = baseline.ID
)
You don't need to bother using the aliases I've added to; I've just added them for readability.
A very simple issue as it appears but somehow not working for me on Oracle 10gXE.
Based on my SQLFiddle, I have to show all staff names and count if present or 0 if no record found having status = 2
How can I achieve it in a single query without calling Loop in my application side.
SELECT S.NAME,ISTATUS.STATUS,COUNT(ISTATUS.Q_ID) as TOTAL
FROM STAFF S
LEFT OUTER JOIN QUESTION_STATUS ISTATUS
ON S.ID = ISTATUS.DONE_BY
AND ISTATUS.STATUS = 2 <--- instead of WHERE
GROUP BY S.NAME,ISTATUS.STATUS
By filtering in the WHERE clause, you filter too late, and you remove STAFF rows that you do want to see. Moving the filter into the join condition means only QUESTION_STATUS rows get filtered out.
Note that STATUS is not really a useful column here, since you won't ever get any result other than 2 or NULL, so you could omit it:
SELECT S.NAME,COUNT(ISTATUS.Q_ID) as TOTAL
FROM STAFF S
LEFT OUTER JOIN QUESTION_STATUS ISTATUS
ON S.ID = ISTATUS.DONE_BY
AND ISTATUS.STATUS = 2
GROUP BY S.NAME
I corrected your sqlfiddle: http://sqlfiddle.com/#!4/90ba0/12
The rule of thumb is that the filters must appear in the ON condition of the table they depend on.
Move filter into the LEFT JOIN , also use COALESCE to have your results display 0 instead of null as you requested in your question
select S.NAME,COALESCE(ISTATUS.STATUS,0),COUNT(ISTATUS.Q_ID) as TOTAL
from STAFF S
LEFT OUTER JOIN QUESTION_STATUS ISTATUS
ON S.ID = ISTATUS.DONE_BY
AND ISTATUS.STATUS =2
GROUP BY S.NAME,ISTATUS.STATUS
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.
