I want something strange here. I've table names as EMP_INFO which contains few details of an employee (i.e. Name,Designation, JOIN_FROM, JOIN_TO). I am trying to figure out term for each employee on yearly basis. I've below types of data
EMP_ID EMP_DESIG JOIN_FROM JOIN_TO Query Result
1 Supervisor 01-05-11 30-04-13 Should Display
2 Supervisor 15-06-10 31-12-12 Should Display
3 Jobar 01-01-12 31-12-13 Should Display
4 SR Superior 01-12-11 31-12-15 Should Display
5 Supervisor 01-05-11 31-12-13 Should Display

Basically what i need is I have date range in my report and let's say From: "01-Jun-11" To "31-Dec-13". From above record set report should retrieve all records as all records contains this both dates.
I have tried by using BETWEEN syntax but i believe it will not work.
If anyone can help me in this than it would be appreciated.
Thanks in Advance.. And one more thing if this details is not enough to understand than let me know i will add more in details.

Query which I tried
SELECT EI.*
FROM EMP_INFO EI,
(SELECT
TO_DATE('01-JUN-2011','DD-MON-YYYY') A,
TO_DATE('31-DEC-2013','DD-MON-YYYY') B FROM DUAL) X
WHERE
(EI.JOIN_FROM IS NOT NULL AND EI.JOIN_TO IS NOT NULL)
AND (
X.A BETWEEN EI.JOIN_FROM AND EI.JOIN_TO
AND X.B BETWEEN EI.JOIN_FROM AND EI.JOIN_TO
OR (EI.JOIN_FROM >= X.B AND EI.JOIN_TO <=X.A) )
Modified Added column (Query Result) on above table which contains result for each record.
So you simply want all records where the join time is in the given time range? That would be:
SELECT *
FROM EMP_INFO
WHERE JOIN_FROM BETWEEN
TO_DATE('01-JUN-2011','DD-MON-YYYY', 'NLS_DATE_LANGUAGE=AMERICAN') AND
TO_DATE('31-DEC-2013','DD-MON-YYYY', 'NLS_DATE_LANGUAGE=AMERICAN')
AND JOIN_TO BETWEEN
TO_DATE('01-JUN-2011','DD-MON-YYYY', 'NLS_DATE_LANGUAGE=AMERICAN') AND
TO_DATE('31-DEC-2013','DD-MON-YYYY', 'NLS_DATE_LANGUAGE=AMERICAN');
EDIT: Sorry, I got it now. You are looking for all time ranges that overlap with the given range. That would be: ranges that start before and end within, ranges that start before and end after, ranges that start within and end within and ranges that start within and end after. Another way to express this is: Either the given time range start is within the other time range or the other time range start is within the given time range. Here is the according statement:
SELECT *
FROM EMP_INFO
WHERE JOIN_FROM BETWEEN
TO_DATE('01-JUN-2011','DD-MON-YYYY', 'NLS_DATE_LANGUAGE=AMERICAN') AND
TO_DATE('31-DEC-2013','DD-MON-YYYY', 'NLS_DATE_LANGUAGE=AMERICAN')
OR TO_DATE('01-JUN-2011','DD-MON-YYYY', 'NLS_DATE_LANGUAGE=AMERICAN')
BETWEEN JOIN_FROM AND JOIN_TO;
And here is the SQL fiddle: http://sqlfiddle.com/#!4/b58b3/3
Convert to same format and compare. There may be a time component in the dates stored in database. Previous answer was wrong.

I want to do a forecast model in excel, which automatically calculates the expected monthly values of a certain variable.
Table A (Output table):
here, I want to show the expected end of month value for a patientF.ex. I want to forecast the total value of X for Person A for the whole month of October
enter image description here
Table B (Data table):
Here, I receive a daily import from an SQL database with the relevant Person Data for that day
F.ex. on the 15.10.2021 I would receive the following:
enter image description here
In short, I would like to do the following calculation in my output table B:
Return Value of "Number of X", given that "Patient" =Person A for the MM/YYYY match (if successful, this should show 13 for person A/October in the output table)
Secondly, I want the above value to be divided by the number of days of that particular date (so 15 days in this example)
Thirdly, I want to multiply it by the total number of days for that given month (as indicated in the Output table/Date section)
I have tried different sumifs/array formulas but I really struggle with one consolidated formula. Any help/tips much appreciated!
I have a long database of observations for individuals. There are multiple observations for each individual, all assigned different medcodeid's.
I want to extract all records of individuals with certain medcodeid's assigned, but only if they at some point have had a smaller list of specific codes assigned.
This is an example of what I start with:
long dataset, multiple observations
and this is the records I'd like to extract:
multiple observations, but patients 3 and 5 are not extracted, as they never had a medcode 12
Would this be an additional WHERE clause? I am struggling as this will then only extract the second AND medcodeid list. But I want it to extract all, if the individual has had one of these certain fewer codes at some point. I hope that makes some sense. I am unfamiliar with IF command? And cannot see how CASE WHEN would work either.
Thank you very much in advance!
You definitely don't want to filter out all the rows so you're right that an additional condition won't help with that. And where only lets you look at the current row and you're trying to make a decision based all the rows belonging to the patient.
This query just uses a table expression and an analytic count() that tags each row with the number of matches as it lets you look outside the current row just like you need.
-- my additions to your query are in lowercase
with data as (
SELECT obs.patid, yob, obsdate, medcodeid,
count(case when medcodeid IN (<list of mandatory codes>) then 1 end)
over (partition by obs.patid) as medcode_count
-- assuming the relationship looks something like this
from obs inner join medcode on medcode.patid = obs.patid
WHERE medcodeid IN (<list of codes>)
AND obsdate BETWEEN '2004-12-31' AND GETDATE()
AND patienttypeid = 3 AND acceptable = 1 AND gender = 2
AND YEAR(obsdate) - yob > 15 AND YEAR(obsdate) - yob < 45
)
select * from data where medcode_count > 0;
At first I thought you were requiring that at least five of the codes from the full set were found. Now that you've edited the question I believe that you want to require that at least one code from a smaller subset is present. Either way this approach will work.
If I'm understanding what you're asking, I think what you need is an additional WHERE clause with a subquery. This could be done with and EXIST or a join but I find an IN query to be easier to work with.
You left the FROM out of your query so I had to guess at it but try this:
SELECT
obs.patid,
yob,
obsdate,
medcodeid
FROM
obs
WHERE
medcodeid IN (list of 20 codes)
AND (obsdate BETWEEN '2004-12-31' AND GETDATE())
AND patienttypeid = 3
AND acceptable = 1
AND gender = 2
AND ((YEAR(obsdate))-yob) > 15
AND ((YEAR(obsdate)) - yob) < 45
AND obs.patid IN (
SELECT
obs.patid
FROM
obs
WHERE
medcodeid IN (5 of the 20 codes)
);
I have a SQL query which returns three columns Contact Id's, No of participations, Year of participation.
Based on this query result, I need to look for the pattern if anyone attended for certain (same number every year) number of times over the years.
For example, 2 times every year or 3 times every year for 2 years or more consecutively (and not different number of times in each year).
From the sample below, contacts I would be interested to be pulling are 1008637, 1009256, 1010306 & 1011263
Please let me know how to achieve this.
Please see image for sample data.
You would need an aggregation twice. Once to get the number of participations and then to check the number condition for each year.
select id
from (select id,year,count(*) as num_participations
from tbl
group by id,year
) t
group by id
having count(*) = count(distinct case when num_participations = 2 then year end)
I have a table that has an auto-incrementing identity "Reference" field and a pair of other fields that determine the sort order. What I need to do is find the 'next' item in the table when sorted based on the pair of fields based on the reference field of an initial item.
So my data looks like this when sorted by SortParent.SortChild:
Reference SortParent SortChild Data
------------------------------------------
9 1 2 Fred
7 1 3 Jim
11 1 4 Sheila
4 2 1 Micro
5 2 2 Archimedes
12 2 3 Electron
So in this example the "Jim" row (Reference=7) comes after "Fred" (Reference=9) even though it's reference is smaller.
So i want to be able to find which row comes after Fred by searching based on Jim's reference
At the moment in code I do a query to find the values for Fred's row:
SELECT SortParent,SortChild From MyTable WHERE Reference=9
Which returns 1,2. Then do a search for the first row that comes after 1,2:
SELECT * FROM MyTable
WHERE ((SortParent=1 and SortChild>2) OR (SortParent>2))
ORDER BY SortParent,SortChild
Which will therefore come back with the row having reference 7 and sort values 1,3
I'm pretty sure this can be done in a single query, but i'm stumped on the best way.
Incidentally, if anyone has any suggestions on alternate way of handling the two part sort columns that would make this easier, please feel free to help!
I believe You are looking at the LEAD or LAG windowed function:
https://msdn.microsoft.com/en-US/library/hh213125.aspx
SELECT
NextReference
FROM
(SELECT
reference
, LEAD(reference, 1,0) OVER (ORDER BY SortParent,SortChild) AS NextReference
, *
FROM
mytable
) newTable
WHERE
reference = 9
I used LEAD, but try it with LAG if you are looking in the other direction for the row
I havn't tested this particular query, so my not be syntactically sound, but let me know if you have any troubles with it and I'll go over it a bit more once I'm back at my desk
EDIT: Used the wrong sql from your question as my base
EDIT2: Put the lead into a subquery to allow us to query on it
Background
I have a database that hold records of all assets in an office. Each asset have a condition, a category name and an age.
A ConditionID can be;
In use
Spare
In Circulation
CategoryID are;
Phone
PC
Laptop
and Age is just a field called AquiredDate which holds records like;
2009-04-24 15:07:51.257
Example
I've created an example of the inputs of the query to explain better what I need if possible.
NB.
Inputs are in Orange in the above example.
I've split the example into two separate queries.
Count would be the output
Question
Is this type of query and result set possible using SQL alone? And if so where do I start? Would it be easier to use Ms Excel also?
Yes it is possible, for your orange fields you can just e.g.
where CategoryID ='Phone' and ConditionID in ('In use', 'In Circulation')
For the yellow one you could do a datediff of days of accuired date to now and divide it by 365 and floor that value, to get the last one (6+ years category) you need to take the minimum of 5 and the calculated value so you get 0 for all between 0-1 year old etc. until 5 which has everything above 6 years.
When you group by that calculated column and select the additional the count you get what you desire.
