Using Access 2013 I have a calculated a column in a query that is the datediff from a clients intake date to now(), the formula is:
DateDiff("d",[table1]![intake_date],Now())
So the column will give the total number of days the client has been our client. This works great. Each client has a total number of days populated. Now what I want to do is add those numbers up to find the total number days from that column. What I can't figure out is how to get a sum of that column to populate in a textbox. I have a form with a textbox that I want to sum to show in. The formula I assumed would work is
=Sum([queryname]![columnname])
but that is not working.
=Sum([columnname])
can only be used if columnname is a field in the form's RecordSource.
Typically in the footer of a continuous form.
To show the sum of a query that is independent of the form, use the DSum function:
=DSum("columnname", "queryname")

I have a report. This reports returns a lot of rows. One of the columns is qty_req (quantity required). I need to AVG() this column and put the value of the average at the bottom of the report. The problem is that sometimes some rows have a zero in this column. I want the average to exclude any rows where there is a zero. How can I accomplish this?
What I've tried: I tried using DAvg in the query but it made the query time enormous.
Avg() ignores Null values. So you can use an IIf() expression to swap Null for your zero values, and then base the Avg() on that IIf() expression.
Here is the Control Source for a text box in my report's footer:
=Avg(IIf([gainOrLoss]=0, Null, [gainOrLoss]))
gainOrLoss is a field in the report's Record Source. And the text box displays the average of all those values which are neither zero nor Null.
Well then you can't use a calculated SUM() or AVG() field, simple as that.
These functions always use all rows in the report.
You need DSum() or DAvg() to calculate it separately.
If that's too slow, you need to tackle this problem.
I have a report that I built in SSRS that calculates a sum of numbers for every business day going back 10 business days. There is a column group for each business day, and there are row groups for each item being totaled. The function to calculate the sum is a simple:
=Sum(Fields!INCOME.Value)
This returns data for example as such:
Now I am creating a report to indicate the change in data from day-to-day. I figured this would be simple with the Previous() function in SSRS. So I took the same dataset and in a new tablix I replaced the original calculation with:
=Sum(Fields!INCOME.Value)-Previous(Sum(Fields!INCOME.Value),"ASOFDT2")
The Column group is called ASOFDT2. This seems to work for all but the very first column, I get the following as a result:
My question is, does anyone know why this calculation is not performing in the first group, but is for all the rest? How can I make it properly calculate the first iteration of this? For informational purposes, I'm using SQL Server 2014, and I am building the report in Visual Studio 2013.
I have also reviewed the SO question: Use of Previous() function in reverse date sorted data in SSRS? though I am not sure how to apply this to my problem. The first column is my most recent set of data and I cannot select one column newer and just hide it.
The Previous() function gets the data in the Previous column. It doesn't have any understanding of what that data is, so if your columns are in Descending order, the Previous column will be the Next day, not the Previous day
It shouldn't be too hard to include the differential data in your dataset instead of trying to calculate it in the report. Just join the table to itself on YourDateColumn = DATEADD(dd, -1, YourDateColumn), and the right side of the join will have the previous day's data, and you can subtract for the difference.
I have a table field in which I want to calculate the price of an order. In that table I have a field where you choose what dishes did the client order. And I need to get the prices of those exact dishes from another table and then sum them up. I want to calculate in field SASK and take prices from table VALGIARASTIS. So what should the formula be?
For example in field dish I choose Balandeliai,Bulviniai blynai, Cepelinai formula should take those names and get prices of it from table VALGIARASTIS and sum them up.
Here's a screenshot for you to understand.
The solution will not be a formula. It will be a VBA function that receive an array from the multi-value combo box, uses it to build a filter for the data in the VALGIARASTIS table, and uses an aggregate query to SUM() the price values.
For the first part, you can refer to these links:

Once you have the means to filter a recordset, you can run an SQL query on the results using the SUM() function to get your total. You can run a DAO cursor through the recordset and get your total that way, but SQL is better.
I swear this shouldn't be that hard, but it's been a real struggle.
I have a query that returns a site name, an event date, and the count of events. I use it in a very nice chart to show events by day.
I now want a Tablix to show the sum of those count of events by site. That is, ignore the date and just sum the counts.
I know I can write another query to accomplish this, but I'd rather minimize the number of queries in this report. How can I use the existing query to create the Tablix that I want?
in the tablix, create your group/groups that you want to sum by, then add the sum of the field you're summing. If you exlude the date in the groups then it'll just sum by whatever you group by.
I have a database to calculate my expenses. I record expenses with negative numbers, and salary with positive numbers. When I make the month report, and sum the values, it sums it all including salary. I want to code of Visual Basic to sum negative numbers only. I know about Filter property, but the Filter I put disappears when I close database. Can you help me, please?
You can build your report using a query or use the Where argument of the OpenReport method of the DoCmd object in versions of Access since 2003.
EDIT re comment
The easiest way to create a query is to use the query designer, viewed in SQL View, you should see something on the lines of:
SELECT Amount
FROM MyTable
WHERE Amount <=0
