I am trying to get a date difference to determine cycle time of when something arrives to completion. However, I need the product to count towards cycle time average for all days it is here. So, something along the lines if arrivdate='8/16' but completiondate='8/24', I need for the cycle time for this product to be 1 on '8/17', 2 on '8/18', etc until it is 8 on '8/24' and then stops counting. I am willing to do it in either Excel or SQL, if there is a fast way to do it. Below is an example of the data in an Excel sheet
https://drive.google.com/open?id=0B4xYGwf8uS7ZdE5YRDYzXzNuOTQ is a link to the file, as I'm not sure how to insert a table in here.
Does this suit?
If I understand your question properly this simple formula should work. You can replace the 0 with "" to leave it blank

Recently I created an automated production scheduling tool through Excel that assigns a rank to items being produced in the same process, and then uses that rank in combination with the workload to create a schedule.
It functions exactly the way it is intended to, but due to the large amount of data and it being excel it has very slow performance, which is why I am looking to move the calculations over to SQL.
The general logic is like this:
-Always produce everything from the first day before the second day
-Always produce items from an earlier rank before items from a later rank
You can see how this plays out in the image below, where the line has 21.5 hours today, so items will be produced on day 1 until it equals 21.5, where the remainder is then carried over to day 2 and so on.
I was able to do this in excel using lengthy positional based formulas, but I am trying to think of a way to get the same result in SQL without having to rely on looking at the row above.
I am not sure how to convey something like 'Subtract from the available time production time of higher priority items produced on the same day'.
I apologize if the question is unclear, but any advice would be appreciated.

Thanks to shawnt00, that put me in the right direction. Ultimately I had to modify the case statements a bit to go off of the cumulative total instead, but I was able to get the desired results using a sum() Over (partition by order by ) statement.
I have a particular data set that consists of information for projects our company works on. Each project can go through five different statuses and we have a column that records each date the project is put into that particular status.
Now for the Excel part. We are trying to calculate the days in each status and find the total project time. The total is easy to do, because I can use network days between the project submitted date and the project go live date. The statuses, however, are giving me issues because sometimes a project will skip a status, leaving the date field empty. So what happens is a project goes from status B to status D, the formula for days in status "B" look for a date in column "C" to use as the second date in a NETWORKDAYS formula. When it is empty, the IF argument tells the formula to use TODAY() as the second date. What I need it to do is the search the columns to the right (within the given range of A:E for that row) and use that date if it exists. If not, then it can default to TODAY() because this would be an "active" project that has not moved on.
=IF(IF(OR([#STALLED]<>"",[#CANCELED]<>""),"",IF([#INTAKEDATE]="","",IF([#SCOPEATE]="",NETWORKDAYS([#INTAKEDATE],TODAY()),(NETWORKDAYS([#STATUSADATE],[#SCOPEATE])))))<0,"",(IF(OR([#STALLED]<>"",[#CANCELED]<>""),"",IF([#INTAKEDATE]="","",IF([#SCOPEATE]="",NETWORKDAYS([#INTAKEDATE],TODAY()),(NETWORKDAYS([#STATUSADATE],[#SCOPEATE])))))))
This is done for each of the statuses so the table looks something like this:
PROJECTID PROJECTNAME INTAKEDATE SCOPEATE BUILDDATE TESTDATE GOLIVEDATE INTAKEDAYS SCOPEDAYS BUILDDAYS TESTDAYS
If there is any Macro or better formula someone could help me figure out, I'd appreciate it. There is also another field that gives the current status or if the project is considered live if that helps at all. I have excel-block right now and cant think of anything that makes sense for this.
So I figured it out using MIN and by adjusting the IF formulas a bit. Whoever it was that posted about MAX earlier, really helped me out getting me down this path. Kudos to you sir/madam.
I had to add the check to see if SCOPEDATE=BUILDDATE because without that it was returning 1 if the dates matched, with was adding one more day when compared to running the networkdays from INTAKEDATE to GOLIVEDATE.
=IF(OR([#STALLED]<>"",[#CANCELED]<>""),"",
IF([#SCOPEDATE]="","",
IF([#SCOPEDATE]=[#BUILDDATE],0,
IF(NETWORKDAYS([#SCOPEDATE],(MIN([#BUILDDATE],[#TESTDATE],[#GOLIVEDATE])))<0,NETWORKDAYS([#SCOPEDATE],TODAY()),NETWORKDAYS([#SCOPEDATE],(MIN([#BUILDDATE],[#TESTDATE],[#GOLIVEDATE])))))))
I hope this is helpful for someone else.
A little background on the report:
This is a productivity report for our employees working at our business. We determine their productivity based on the duration of the visits with clients. Some of our employees offer group sessions. They charge each client within the group, even though they are only giving, for example, one hour of service, they can bill for 10 hours if there are 10 people in the group. We determine what service they gave by service codes.
So, I have two fields in this formula, a service code field and a duration field.
The duration field is initially a STRING field from the database, even though it only gives number data, so I change it to a numberVar. The service code field is also a string field, and it sometimes does contain characters and numbers.
What I need Crystal Reports to do is take the sum of the duration. However, if the service code is, say, "1000", it must first divide the duration by 3 before summing it. This is where I get caught up.
Here's my code for the duration:
local numbervar num1;
If GroupName ({billing_tx_charge_detail.v_SERVICE_CODE})="1530" then
num1 := ToNumber({billing_tx_charge_detail.v_duration})/3
else num1 := ToNumber({billing_tx_charge_detail.v_duration})
Then I do a separate formula for the sum, named sumDuration:
Sum(#duration)
I get the error that this field cannot be summarized. After searching Google for two days I have found that Crystal cannot summarize fields or formulas involving constants. If I simply say:
local numbervar num1;
num1 := ToNumber({billing_tx_charge_detail.v_duration})
then I can summarize #duration. What am I missing? It has to be something simple, but I'm just not seeing it. Is there a way to create a custom function to accomplish what I am trying to get here? Or is it even simpler than that?
One person suggested creating a SQL command in order to do the calculations before the data gets to the report. I am a SQL newb so I had no idea where to even begin with that.
If you are grouping by Service Code and placing the above formula in the footer you will only be computing {billing_tx_charge_detail.v_duration} for the last record in the group. If you are intending to use the formula and sum the results and place the results in the Service Code footer try the following. (basically remove the reference to group name)
If {billing_tx_charge_detail.v_SERVICE_CODE}) = "1530" then
ToNumber({billing_tx_charge_detail.v_duration})/3 else
ToNumber({billing_tx_charge_detail.v_duration})
You can use variables (num1) if you want to but they are not needed.
You can still use the second formula you referred to and place in the group footer OR you can place the first formula in details section, right click and insert a summary to the group footer. You can also place in the report footer if you need it to total there as well.
I have a view that lists employee (EmpID), request number (ReqNo), date request was opened (OpenDate) and the date it was moved to the next step in the process (AssignDate). What I am trying to do is get an average of the daily queue size. If EmpID 001 has 20 requests on 1/1/13, then has 24 on 1/2/13, 21 on 1/3/13 the average over 3 days should be 21.66, rounded up to 22. I have the following view:
CREATE VIEW EmpReqs
AS
SELECT [EmpID], [OpenDate], [AssignDate], [ReqID]
FROM [Metrics].[dbo].[Assignments]
WHERE OpenDate BETWEEN '01/01/2013' AND '12/31/2013' AND
[EmpID] IS NOT NULL AND
[ReqNo] NOT LIKE 'M%'
I then wrote a query to pull individual employee's queues per day:
/* First attempt to generate daily queue #s */
SELECT * FROM BLReqs
WHERE [BusLiaison] LIKE 'PN' AND
[OpenDate] <= '11/15/2013' AND
[AssignDate] > '11/15/2013'
Because no one has attempted to pull this information before, I have no way of verifying how accurate the above is. I tried using current dates, since I can see those in our database to compare but the code doesn't work, nothing is returned when I change the dates to 2014 and run my query.
What is the easiest way to verify that my code is correct, short of manually counting a day's queue?
Can anyone see any issues with the above scripts?
Is there a way to get the above code to work with current dates?
This question is really hard to answer because it is kind of broad and has little information at the same time. I'll try anyway:
Because no one has attempted to pull this information before, I have
no way of verifying how accurate the above is.
Try checking the result of this query for a few sampled dates.
I tried using current dates, since I can see those in our database to
compare but the code doesn't work, nothing is returned when I change
the dates to 2014 and run my query.
So clearly, the query is not working. You should probably find out why. Run the query for a date of which you know that it should return results but doesn't. Remove conditions one by one to see which one is incorrectly removing all rows. This should be enough to identify the bug.
Can anyone see any issues with the above scripts?
No, looks fine. A very simple query. That's why I said that we have too little information. There is some key piece of information missing that allows us to find the bug.
Is there a way to get the above code to work with current dates?
Stop staring at the code and hoping for a revelation. Debug it. Experiment.
Im making a simple booking system for our projectors at work.
Here is the scenario. Each projectors can have its availability set to quarter hour segments throughout the entire day. i.e projector 1 is available between 8:15am - 1:45pm and 3pm-5:15pm each day (can also be changed to have different availabilities set for each day). A projector can be booked for anytime time segment during the day as long as it is available. So ive got that setup in my sql database (with my asp.net mvc front end).
The question i have is what is the best way to search on this scenario. i.e. UserA comes in and says find me the projectors that are available this friday between 12pm-3pm. Im struggling to write an efficient sql query that will filter this. My best option so far is to pull back all projectors and than programatically work out if they are available and not booked between this time. It works but it is incredibly inefficient. I stumbled an idea of using a temp table generated by a stored proc that can than be filtered but it isnt quite there.
Has anyone got any ideas how i could approach this?
Thanks in advance
I would probably have a table called ProjectorReservations which contained a start time and end time (amongst other fields you might care about i.e. who is renting the projector).
Searching a projector would look something like this:
SELECT projectorName
FROM Projectors
WHERE NOT EXISTS
(SELECT 1 FROM ProjectorReservations
WHERE Projectors.projectorName = ProjectorReservations.projectorName
AND (ProjectorReservations.startTime < {end_time}
OR ProjectorReservations.endTime > {start_time}))
That pretty much checks to make sure no reservations start before the one you are looking for ends and vice versa. Obviously you will need to swap in your fields accordingly but that should give you the general idea
