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 pivot table with week number (columns) versus product (rows). I want to see the top 10 products, based on sales, per week, a value of 1 would indicate the product is in the top 10. I'm using the expression below and I'm getting the Top 10 sales over all weeks. How do I get a weekly top 10 (each column would have ten values)?
=if(Aggr(Rank(sum([SALES])),PRODUCT)< 11,1,0)
I would say you are almost there, but you need to add another parameter to the Aggr function (like you've said you want the rank by Product and Week, and currently you are only taking Product into account).
Without knowing the details of your model, the expression would be something like :
=if(Aggr(Rank(sum([SALES])),PRODUCT,WEEK)< 11,1,0)
I am new to SQL and Stack overflow and have a question about SQL Server syntax. i have searched online but I am not finding what I need and I would appreciate your assistance in this matter.
I have data in a source table for meal orders (each with a specific ID (e.g. 12345C) and items of each order (e.g. sandwich, drink, chips), each with an associated number starting with 1. For instance, the sandwich would have an item number of 1, the chips would be item # 2, and the drink would be item # 3 for the same orderID 12345C. The prior example would therefore have 3 rows of data in the source table for orderID 12345C.
My questions are these:
how do I use a SQL expression to determine the number of items per each order (e.g. 3 for the above example, which is also the maximum value for item number for each orderID)
and then add all of these items per order across hundreds of orders per day to determine the daily total number of items ordered.
So, if I had 3 orders in one day - one with 2 items, the second with 3 items, and the third with 4 items, I would like my final number to be 9.
This number is for use in a Sisense dashboard that allows SQL syntax in the field definition. Thank you for your help!
It is a bit difficult to explain but I am not able to use a query from a table because I am working with a dashboard in Sisense so I am adding fields in a pivot display and one of the fields I would like to include is the total count of order items per day (across several dozen orderIDs).
Here is an example of the data in the table: from the example I would like the final answer for orderID 1787588 to be 3 (there are 3 items within the order).
I am able to calculate how many employees are working using DAX measures:
Number of employees started := CALCULATE(COUNTA([Emp from]);FILTER(ALL(tDate[Date]);tDate[Date]<=MAX(tDate[Date]))) -
Number of employees quit := CALCULATE(COUNTA([Emp unitl]);FILTER(ALL(tDate[Date]);tDate[Date]<=MAX(tDate[Date])))
Number of employees working := [Number of employees started] - [Number of employees quit]
But I have not managed to calculate how many full time equivalent employees are working. Each employ has a workload from 0% to 100%.
How can I calculate the number of full time equivalent employees?
I have tried the following for number of full time equivalent employees started, but in contrast to the measures above it doesn't accumulate over time. It just shows the results for each individual month:
Number of full time equivalent employees started:=CALCULATE(SUMX(tEmployees;tEmployees[Workload]*Not(ISBLANK(tEmployees[Emp from])));FILTER(ALL(tDate[Date]);tDate[Date]<=MAX(tDate[date])))
Do you have any suggestion for how I can solve this?
You might try something like this. In your Emp table have the start date and end date for the employee. In your measure you would use the calculatetable function to create an in memory table that has one row for each date in your date table and each employee id. This same in memory table would take the work percentage and create a column that that represents the number of hours worked by that employee on that day. Then you just need to express number of 'equivalent' employees as: sum of number of hours worked/(number of hours in a 'full time work day' * count of days in period). This should give you a measure you can use along with your dates to find the number of full time equivalent employees in on any given day or over any given period.
See my sample table structure in this TechNet forum post. This is a modelling problem first, and a DAX problem second.
Once you've created your headcount fact, all of this becomes trivial.
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.
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

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.
Modified
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;

Convert to same format and compare. There may be a time component in the dates stored in database. Previous answer was wrong.
