once again I have a problem for which I am looking for some hints...
I still have one table, called tblTransactions, which contains security market transactions. For each buy and sell order, respectively it contains one data set with columns Date, Ticker (i.e. the unique identifier of each security), Quantity (positive for buy, negative for sell orders) and Price (at which the trade was executed).
The following code gives me all stocks, which are no longer part of the portfolio since they have been sold out completely for any arbitrarily chosen date (here 1/30/07) together with the date, on which the last position in a certain stock (identified by the ticker) were sold:
SELECT T.Ticker, max(T.Date) AS SellDate
FROM tblTransactions AS T
WHERE T.Date<=#1/30/2007#
GROUP BY T.Ticker
HAVING sum(T.Qty) =0
ORDER BY T.Ticker;
Now it becomes complicated: What I am looking for is a sub-query, which I want to add to the code above and which gives me the weighted average price at which the stocks were bought and sold, respectively if there have been more than one buy or sell transaction.
That is, for the following sample data of tblTransactions...
Now there will be many patterns, the above however only contains one (called 1). Now what i need is the average Depth, Subdrill, Burden, Spacing, bcm/h. In MS Excel I would have following:
Average BCM per hole = Sum of BCM / Sum of Holes
How to do this in Access? Then just to make it more difficult I want to have the average BCM for each different pattern.
In my database, I have clients and client hours. I need to calculate average client hours. My total client hours expression is: TTotals: Sum((Nz([SessionHoursCompleted])+Nz([OptionalHoursCompleted]))). I need to divide this number by the number of clients. Any suggestions ie sum of client number, sum of clients, count of clients. I've tried these and the results are incorrect.
I am trying to calculate the average patients age from 2671 records using this SQL:
SELECT tbl_Customer_Details.DOB, CalcAge([DOB]) AS Age, DAvg("[Age]","qryAvgAge") AS Average FROM tbl_Customer_Details GROUP BY tbl_Customer_Details.DOB, CalcAge([DOB]);
why am I getting the result:
68.1131066106
I would have thought that it would have been 68 a whole number, has anyone got any suggestions why this should be.
My database has 8 clients. During a sample date range, between 1/1/05 and 1/1/11, they worked a total of 348 hours. I need to query them for hours divided by client by date range. 3 clients, for instance, worked a total of 162 in the sample date range but the query is dividing the 162 hours worked by all 8 clients. I need it to divide the hours in this case by 3. Needless to say, these numbers will change when a different date range is inputted but if the expressions are correct... Currently, to calculate this number I am using this expression : Averages: Sum((Nz([SessionHoursCompleted])+Nz([OptionalHoursCompleted])))/DCount("IDOC","spise clients_OLD_OLD"). A copy of the query 'Current Average/Total' is attached.
Is there a way to calculate three different rolling averages in one query?
I just inherited a database where someone is using three queries to capture the same information only with different time frames. They were calculating a rolling three month average, six month average, and twelve month average. I would like to combine these queries into one to reduce time spent running reports from the database. All three queries are based on one table. One of the columns in that table is called "Month Start Date". That field shows the first day of the month when a call was entered. I can get the query to tell me the first month in the three month period and the first month in the six month period, but I can't get it to calculate the averages of the calls that fall in those time frames. Here is the SQL for the query I have now. When I try to run this, I get the error message that my formula is not part of an aggregate function.
Code: SELECT DISTINCT DateAdd('m','-2',(Max([Month Start Date]))) AS ThreeMonthStartDate, DateAdd('m','-5',(Max([Month Start Date]))) AS SixMonthStartDate, Max([Month Start Date]) AS MaxStartDate, IIf([Month Start Date] Between [ThreeMonthStartDate] And [MaxStartDate],Avg([All Call Rate]),' ') AS ThreeMonthAverageCallRate, LIST_WITH_TNC.Device, LIST_WITH_TNC.Model, LIST_WITH_TNC.[Item Num] FROM LIST_WITH_TNC;
I've searched hours on the forum but with no luck. If there's anyone out there who can help me would be very much appreciated.
The calculation in Excel is very simple but I am unable to replicate in Access. Please don't confuse this with FIFO calculation as it is purely Weighted Average Cost method based on Buy unit prices i.e Sale unit prices are not required as it will sell at the Average Cost of the Buys upto the point of Sale.
i.e. Buy 100 @2 = 200 Buy 100 @3 = 300 Total 200@ 2.50 =500 Sell 100 leftover will be Total 100 @ 2.50
I am attaching an Excel S/sheet which shows the Calculation of Stock ABC and the Average Prices (which is what I am trying to achieve). I have also attached an Access Dbase with same details but without any calcs as whatever I have done I am unable to achieve my result.
I'm having a problem getting a report textbox to display the average value that I want.
Background:I have a DB that tracks student grades. The course is organized into blocks, with several tests in each block. Students can take the same test multiple times, in cases of failure, or if they get rolled back in class. The DB tracks whether or not each test is a retest or audit.
The tests are also weighted. For example, the Geo Quiz could be worth 10% of the grade for a block, and the final exam 90%.
Goal:My report needs to display the class number, student name, block, test, and associated scores; it needs to show the total grade for each block; and it needs to display the student's average grade across all blocks. I need to be able to generate the report at any point in the course, not just after all blocks and tests have been completed.
Setup:Since I want to display the assigned grade, but calculate the weighted grade into the block grade, I set up a query (qryWeightedGrades) to calculate the weighted grade for each test (e.g. Score of 98%, weighted at 10% of block, results in a 9.8 for the weighted grade). When it comes to calculating the block grade, I just sum the weighted scores.
In the report (based on qryWeightedGrades) I have the grouping levels set up for Class#, Student name, then Block; the test name, score, weight, retake info, audit info, etc. appears together on a row.
How to do, get the average of all the block grades. I can't get the textbox in the Student Name group level footer to average the Block grades in the Block group level footer, without getting an error. I've thought of creating another query that averages the block grades for each student, but how to incorporate that into the footer of the Student Name group level.
Here's an example of what I want the report to look like:
I have a database containing values in 16 fields. the fields are filled in over a period of three years. I would like to be able to calculate the average of the last four values entered, regardless of when in the cycle the value is required. I have tryed to use quereies but connot find away to assign the four fields to the expression so that it is the last four values and if four don't exist, avearage what values there are.
I have a table containing about 120 records of 40 fields containing integer values. The values are 0 (for 'no experience'), 1 - 5 (for evaluation of experience) and 9 (for question not answered). I would like to generate a row of averages for the 40 columns.
Access includes the '0's when using the Avg function. (So 1,0,3,0,1,4 yields 1.5 (1+0+3+0+1+4 / 6) rather than the accurate 2.25 (1+0+3+1+4 / 4)). I can tackle this in two ways: I either convert all zero's to NULLs, as Access will not count NULL in an Avg function call, or I can do each column in a seperate query using a WHERE clause. I also have the problem of screening out the 9's. I'm reluctant to create 40 queries and then another to amalgamate the results as this seems a very silly way to solve this problem. I cannot convert both the zeroes AND the 9's to NULL as to do so would lose valuable data.
Can anyone suggest how I can obtain a full row of averages for the 40 fields, ignoring 0's and 9's?
Im in need of some help with a query that i am trying to set up. I have a table with data shown roughly below. And need to extract the average [call length] for each heading of [Call type] on a given date.
Ie. The query will be run and the date can be inputted. It would the display each category only once and the average of that category.
I need to create a query where in the end, I will have four rows of data based on based on two combinations of WaterSourceType and Crop.
I need the query to bring back the results of the average Top N (lets say Top 10%) for each combination.
I have tried this every which way and I can't seem to get it grouped like I want it. I NEED to have four distinct rows with the average of the ProfitPerBushel for each grouping.
Basically, what this does is show me the average profitablity of the top 10% in each grouping.
My database is set up to track call evaluations with 4 fields for number data (S, A/C, C/E and B) each of these have a possible point total. I also have a percentage field to track out of total possible points.When I run my query I get a list of each of the totals for each of the evaluations with the associates names (as expected).I take that query and try to run a report wizard to give me an average socre for each associate. and the system returns averages of 0 or an odd number that does not make sense.when I use the =Avg([fieldname]) process I get an accurate average of the total but can not get it to do a "subtotal" for each associate.
I am designing queries to return averages for quality test data.
I have this query that functions as I want it too [URL] .....
It returns the averages of all the values received for different tests for a lot number (the lot number criteria should be filled out as well)
When I want the query to be more specific and average only certain box numbers in the lot (that start with the prefix PB") the query does not return an average for box numbers starting with PB but splits them up, showing an average for PB1, PB2 instead of combining the data for those boxes into a single unified average ...
Let's say I have a table sort of like this one: [URL] .... (Table 1)
What I want to do is make another table that references the first table: [URL] ... (Table 2)
I want the cells in the Average field in Table 2 to calculate an average of all the values for records in Table 1 with Color fields that correspond to the Color field in Table 2 (this makes a little more sense if you look at the pictures). I could do this in Excel, but then problems would arise whenever I would add a new entry to the database, or re-alphabetized the data, since Excel math is depends entirely on the positions of cells, and I want these averages to be continually calculated correctly and to change whenever I add related records to the database.
What is the best way to impliment a query in a form so that the user can view the query records, and have the option to print or save the selected record using command buttons?
I tried subforms but I could not get the command buttons to work in the subform after it went into the form, it wanted to print the entire form instead of the selected record from the subform.
So in a nutshell I have 3-4 queries that are built, and I want to have them show up on my form in a format that the user can scroll through the results and select a single record of the results and then print or save that individual record from the form, if such a thing is possible.
In some cases I create pass-through queries and use these in an Append or Make-table query to bring data locally.
All is well and fine until source data changes and the pass-through query runs too long and times out.
If needed, I can extend the timeout value in the Parameters of the pass-through query no problem, but when I try to open the Append or Make-table query in Design view to do the same, the pass-through query is first triggered and then throws the timeout, and I cannot access the Design view of the Append or Make-table
Is there a way to open an Append or Make-table query in Design view without invoking the source query?
I'm trying to run a UNION query that joins five queries through a MS WorkSpace into a DAO.recordset in VB. I'm pulling the data from a SQL Server Database through VB in Access. I'm attempting to open a recordset with a query passed to it as a string. The query is below. For some reason, I'm receiving a message: "MS Jet database engine cannot find the input table or query. Runtime Error 3078".
Here's what's puzzling. When I run a single query without any UNION statement, the code finds the table and runs fine without error, but anytime I join two or more queries with a UNION statement in the VB, it gives me the error.
I've executed the same UNION query in both Access Query Builder and SQL Server's Query Analyzer and they work fine in both environments. It's only when I call the query from a DAO.Recodset with VB that it causes this problem. The following is a sample of the UNION query joining two of the five queries. Does anyone have any idea what could be the problem? The following query executes in about 5 seconds so I don't think there's a "time-out" issue. I'm thinking that the UNION statement may be the culprit. Maybe there's another way to approach joining these separate queries? Any help would be most appreciated. Thanks.

I am wondering if there is a quicker way to export a query to excel then have the data in that query removed from the original table. (effectively cutting the data from the table and exporting to excel)
I understand that this can be done by exporting the query to excel then running the same query as a delete query to remove the data but I just wondered if this is the most efficient way.
I have experience of VB in excel but currently only use the basic macro builder in Access though if Access VB is more efficient I can easily learn.
I run a physical therapy office and patients come in for treatment either 3, 4 or 5 times per week. My database is used to track these frequencies (among other things).
I have 3 queries which count how many patients come in 5, 4 and 3 times/week.
In my main table I have fields called "how many 5's", "how many 4's" and "how many 3's".
I have tried to design an update query which will update those fileds in my main table to reflect the counts in the 3 queries mentioned above.
(I'm not using SQL view, I'm using the query design view)
In the "update to:" row, I use the Build function and locate the count I'm looking for.
Problem: when I run the query I get the error: Operation must use an updateable query.
The ProjRevMRC field is an expression that reads:ProjRevMRC: IIf([ProjRevDate]>=DateSerial(Year(Date()),Month(Date()),1),[CurrentMRC]*[qry303a_ SFADetailMRC_ONLY]![Rev Flow Through],0)
When I run the query, it works perfectly, but when I created a crosstab query to show totals by month, I wanted the totals to be zero for the months less than the current month. Is there a way for the crosstab query to execute the expression and put zeroes for those months?
I have a field that is giving me the number of business days between a period of time and then I want to subtract that number - the person's PTO time to see the actual days they were available...when I simply type the number in (see below) it works great but I want to set up a prompt that will ask me how many PTO Days to calculate as it will be different for each person I am quering...is this possible?
