I'm admittedly new to access so forgive me if there is a simple solution. I have had difficulty searching for an answer as I'm not sure how this needs to be worded...
I have a database containing hundreds of thousands of invoices. I have a query that searches for invoices of the same amount on the same day by the same vendor (with different invoice numbers).
I group by this criteria as well as a count > 1 to display possible duplicates. I'd like to see each record displayed, but it only shows the first invoice number since if I were to group by invoice, the count would be 1 and nothing would get pulled..
I'm sure there is a better way of doing this to achieve the results that I want,. But I am at a loss. If there is further information required to assist, I'll provide what I can.
Thank you.

I am doubting myself on how I should approach this problem.
My users are able to record many parts of their day, including activities, mood, health measurement (heart bpm, glucose), exercise, meals.
I originally thought that I should create one document per entry (i.e. one entry per day). However, when displaying data to the user it rarely occurs on a day by day basis but more on a month by month (charts).
Should I model my Firestore DB in relation to my views or would it be better to just save each entry for each day and then just query?
I am just thinking that it will be more efficient in many parts of the app to have the entries grouped by month than by day.
Am I thinking this right or is there really no benefit? (i.e. maybe the amount of data transferred offsets the costs of unnecessary queries).
If you plane to save each entry for each day and then just query and query to find the result. The more document you'll have, the more document you will query and it will increase you're read/day and so may be more expensive than in a month by month.
To answer your last question :
Let's take an example : if you have a collection with 100 documents.
And you want to query 20 of it.
It will only count as 20 read and not 100 as we might expect.
Just to remind that with firebase you can read up to 50k/day for free, after this limit is it 0.06$/100k read.
I hope it will help you.
Have a nice day !
I am struggling to come up with a formula that fits certain criteria and was hoping someone with a better math brain than me might be able to help. What I have is a Google Sheets based tool that determines how much a someone has purchased of a product and then calculates the amount of times a special additional offer will be redeemed based on the amount spent.
As an example, the offer has three tiers to it. Though the actual costs will be variable for different offers let's say the first tier is gained with a $10 purchase, the second with a $20 purchase and the third with a $35 purchase (the only real relationship between the prices is that they get higher for each tier but there is no specific pattern to the costing of different offers). So if the customer bought $35 worth of goods they would get three free gifts, if they bought $45 worth they would get 4 and then an additional spend of $5 (totaling $50) would then allow them to redeem 5 gifts in total. It can be considered like filling a bucket, each time you hit the red line you get a new gift, when the bucket is full it's emptied and the process begins again.
If each tier of the offer was the same cost (e.g. $5, $10 and $15) this would be a simple case of division by the total purchase amount but as there is no specific relationship between the cost of the tiers (they are based on the value of the contents) I am having trouble coming up with a simple 'bucket filling' formula or calculation method that will work for any price ranges given to it. My current solution involved taking the modulus, subtracting offer amounts from the purchase amount etc. but provides plenty of cases where it breaks . If anyone could give me a start or provide some information that might help in my quest I would be highly appreciative and let me know if my explanation is unclear.! Thanks in advance and all the best
EDIT:
The user has three tiers and then the offer wraps around to the start after the initial three are unlocked once, looping until the offer has been maxed out. Avoiding a long sheet with a dynamic column of prices would be preferable and a small, multicell formula would be ideal
What you need is a lookup table. Create a table with the tier value in the left column, and the corresponding number of gifts for that tier value in the right column. Then you can use Vlookup to match the amount spent to correct tier.
I am not quite sure about, everything into one entire formula(is there a formula for loop and building arrays?)
from my understanding the tier amounts are viable, so every time you add a new tier with a new price limit then it must be calculated with a new limit price number...wouldn't it be much easier to write such module in javascript than in a google sheet? :o
anyways here is my workaround, that may could help you to find an idea

my approach :
- enter purchases value
-> filter all items based by smaller than or equal "<=" (save all item somewhere as placeholder)
-> then decrease the purchases value by amount of existing number(max value) based on filtered items
-> save the new purchases value somewhere and begin from filtering again and decreasing the purchases value
(this needs to be done as many times again, till the purchases is empty)
after that, sums up all placeholder
I'm trying to get all unique visitors for a selected time period, but I want to filter them by date on the server. However, the sum of unique visitors for each day isn't the number of unique visitors for the time period.
For example:
Monday: 2 unique visitors
Tuesday: 3 unique visitors
The unique visitors for the two days period isn't necessarily 5.
Is there a way to get the results I want using the Google Analytics API (v3)?
You're right that Users aren't additive, so you can't simply add them day by day. There are several ways around this.
The fist and most obvious is that if you've implemented the User-ID you should be able to straight up pull and interrogate the data about which users saw your site on which days.
Another way I've implemented before is to dynamically pull the number of Users from the Google Analytics API whenever you need it. Obviously this only works if you're populating a live web dashboard or similar, but since it's just the one figure you're asking for, it wouldn't slow down the load time by much. Eg. if you're using a dashboarding tool such as Klipfolio, you may be able to define a dynamic data source, and query Google whenever you needthe figure (https://support.klipfolio.com/hc/en-us/articles/216183237-BETA-Working-with-dynamic-data-sources)
You could also limit the number of ways that the data can be interrogated, and calculate all of them. For example, if you only allow users to look at data month-by-month or day-by-day, then you only need those figures.
Finally, you can estimate the figure with reasonable accuracy by splitting it into two parts. New Users are equal to New Sessions (you're only new on your first Session), which is additive, so that figure can be separated out and combined as required.
Then, you could take a rough ratio of new to returning Users (% New Users) from, say, 1 year of data, and use that with the New Users figure to generate an average on any level.
Here’s what I’ve done in a spreadsheet:
I’ve assigned people to one or more categories (ie. male, female, tall, short)
I’ve assigned weights to these people (ie. 200 lbs, 120 lbs, 300 lbs)
I’ve assigned names to these people (ie. John, Jane, Bill)
Here’s what I need to do in a plugin:
Find some way to get my data into it (maybe through an admin interface, or via my spreadsheet)
Filter results by one or more categories (ie. only male; only tall + female, etc)
From those filtered results, pull 2 or 3 people (as many as I can fit) whose combined weights equal X or less
Display the names of those 2 or 3 people as a list to front-end users
At the press of a button, randomly generate another 2 or 3 person team
I don’t mind getting my hands dirty, but I don't know where to begin. If you guys could give me any advice, best practices, code to get me started, or names of plugins that already do this, etc, I’d really appreciate it.
Also, if I’m biting off too much for a complete noob, feel free to let me know. Because if it comes down to it, I’ll just create the teams manually and throw them into a random text plugin, or something.
This depends heavily on what format it's in presently. If it's in a spreadsheet, you can import it pretty easily by saving as a CSV and processing it with fgetscsv
Assuming this is going into MySQL (as most WP plugins do), this is just a SQL query (ie WHERE wp_custom_person_record_weight > 100 AND wp_custom_person_record_name != 'Bill'
Same as #2 but with a JOIN and a SUM and a WHERE query against that sum.
This is the same SQL query, if you call it through mysqli_query you'll get an array back that you can output on the page
Random records can be gleaned a number of ways, either by going through a limit of X,2 where X is a randomly generated number between 0 and the # of records or through MySQL itself (although that is not recommended for performance reasons).
To further a personal project of mine, I have been pondering how to count the number of results for a user specified word on Twitter. I have used their API extensively, but have not been able to come up with an efficient or even halfway practical way to count the occurrences of a particular word. The actual results are not critical, just the overall count. I'll keep scratching my head. Any ideas or direction pointing would be most appreciated.
e.g. http://search.twitter.com/search?q=tomatoes
I'm able to go back about a week. I start my search with the parameters that Adam posted and then key off of the smallest id in the set of search results, like so,
http://search.twitter.com/search.atom?lang=en&q=iphone&rpp=100&max_id=
where max_id = the min(id) of the 100 results I just pulled.
net but I have made recursive function to call search query again and again until I don't find word "page=" in result.
