Table 1
Date
Measurement A
Measurement B
Measurement C
Table 2
Table 1 ID Link
Data 1
Tables are linked 1-to-many from table 1 to table 2 by ID.
I would like to average the Data1 data per Table1 ID and report it with the Table 1 Measurements.
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.
WaterSourceType | Crop | ProfitPerBushel
Irrigated | Soybeans | ProfitPerBushel
Non-Irrigated | Soybeans | ProfitPerBushel
Irrigated | Corn | ProfitPerBushel
Non-Irrigated | Corn | ProfitPerBushel
how to return all values in a query when a form critieria is left blank. I have made some progress, the combo box criteria queries were fairly simple, but i'm getting stuck with my date criteria. My query doesn't return null values when I want it to.
I want it to return all records (including null values) if the form OpenFrom and OpenTo dates are blank, and just the values between the selected dates (excluding null values) if the form is completed.
Code:
SELECT qryReportSelector2_Authority.*, qryReportSelector2_Authority.ApplicationDate AS ApplicationDateFilter
FROM qryReportSelector2_Authority
WHERE (((qryReportSelector2_Authority.ApplicationDate) Between Nz([Forms]![frmReportSelector]![OpenFromDate],DMin("[ApplicationDate]","[qryAllCases]")) And Nz([Forms]![frmReportSelector]![OpenToDate],DMax("[ApplicationDate]","[qryAllCases]"))));
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?
I'm using Access 2010. I need to calculate a score based on values selected in a table by looking up corresponding values in other tables. I have a "Project" form to create new entries into the Project table (see Table 1). When I create a new project record, I will select values for the Payback and Need fields by selecting options from a list. The Payback list is pointed at Table 2 and the Need list is pointed at Table 3. In the below example, I created the "ABC" project and selected "1 year" for the Payback field and "Repair" for the Need field. Pretty simple.
Now that I have the "ABC" project loaded to my Project table, I'd like to create a report that will show a "score" for this project. The score should be calculated as follows: Payback Impact + Need Impact. In this example, the score should be 30 (Payback Impact of 20 + Need Impact of 10).
I am reviewing some old database methods and trying to achieve a text box containing the sum of values for items between two dates. At present it is done using a sub-form based on a query of a query.
At first a query collects the values between dates:
Code:
SELECT tblDespatch.Invoiced, tblOrders.Value
FROM tblOrders INNER JOIN tblDespatch ON tblOrders.ID = tblDespatch.JobDespatchID
WHERE (((tblDespatch.Invoiced) Between (DateAdd("m",-3,Date())) And Date()));
and then a secondary query generates the sum of the values:
Code:
SELECT Sum(qrySWBI03.Value) AS SumOfValue
FROM qrySWBI03;
This actually works perfectly but needs two queries and a sub-form for each bit of information and there twelve of them (quotes, orders and invoices for last 3, 6, 9 and 12 months).
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;
Is there a way to make this work?
I have a price table:
Code:
tblPrice
PosNr PriceDate Company Price

8 04.01.2014 Firma XY 7
9 05.01.2014 Firma XY 8
10 06.01.2014 Firma XY 10
And I have a table with the dates, for which I need a price.
Code:
tblDates
PosNr PriceDate Company
1 01.01.2014 Firma A
2 02.01.2014 Firma A
3 03.01.2014 Firma A
4 04.01.2014 Firma A

9 04.01.2014 Firma XY
10 05.01.2014 Firma XY
11 06.01.2014 Firma XY
And now I want to combine this tables, and for the dates which have no price, the last price should be taken.
Code:
tblResult
PosNr PriceDate Company Price
1 01.01.2014 Firma A 5
2 02.01.2014 Firma A 7
3 03.01.2014 Firma A 9
4 04.01.2014 Firma A 8
5 05.01.2014 Firma A 8 (actualy no priceavailable, so take last price)
6 06.01.2014 Firma A 6
7 02.01.2014 Firma XY 11
8 03.01.2014 Firma XY 9
9 04.01.2014 Firma XY 7
10 05.01.2014 Firma XY 8
11 06.01.2014 Firma XY 10
how I can get this?
I have this code, but it need hours.

FROM tblPrices RIGHT JOIN tblDates ON (tblPrices.PriceDate = tblDates.PriceDates) AND (tblPrices.Company = tblDates.Company);
I have a table called StockTable with the following fields Location, Status, Serial, Make, Model, LastDate, DotNumber
I also have a table called FCDateRange with three fields
DateStart DateEnd and DotNumber
For example
3/7/13 - 3/13/13 - 1
3/14/13 - 3/20/13 - 2
Im trying to figure how to write a query that if the lastdate from the StockTable falls during the DateStart and DateEnd fields it will assign it the number in the DotNumber field
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 ...

I have a table which includes a start date field and completion date field for housebuilding.
I am trying to extract all records that have either a started date or a completed date between 2 dates supplied by the user. I have tried to use Between on both fields but that doesn't return results between the fields.
It workd if I just do it on EITHER the start date field OR the completion date field so that implies to me that I need to break it into 2 queries, one returning start date recrods and the other returning completion date records but then I would need to have somthing that removes records that appear in both the start date and the completion date results.
If I want to sum the percentages from April, May and June only if a column is Not Null, how would I do that?
example
Tbl 1
PK, Month
Percent
Tbl 2
FK, Month Enrolled
Qty of Rx in the 1st month enrolled
Qty of Rx in 2nd qtr
Base (if Qty of Rx in 2nd Qtr is null then Qty of Rx in 1st month enrolled)
If Qty of Rx in 2nd QTR is NOT NULL then QTY of Rx in 2nd Qtr * Sum of April Percent+May Percent+June Percent, otherwise Qty of Rx in 1st month enrolled * Month Percent
Im getting stuck on how to sum the percents of April, May and June and then multiplying the result times the Qty ONLY IF the field is not null.
I only know how to create Query's using the design mode. I dont know how to write SQL statements.
For my study on academic research I need to match patents that refer to academic research as prior work with the actual prior work.
I have two tables (see attached images below).
One regarding AcademicPublications (AP), which is neatly organized with title, year, journal, volume, pages, first author, etc... 480,000 rows
One regarding Patentswhere all this information is hidden within one field, in the most messy way possible... for instance, a field could have:
Quote:
Sugita et al, "Nonsurgical Implantation of a Vascular Ring Prosthesis Using Thermal Shape Memory Ti/Ni Alloy (Nitionl Wire)," Trans. Amer. Soc. Artif. Intern. Organs, vol. 23, pp. 30-34.
or
Quote:
Willingham et al., Cell 13, 501-507 (1978).
Or many other ways.
I want to create a new table that is set up like this:
Patents.PatentNumber | AP.ID | Patents.Reference | AP.Title | AP.Year | AP.Volume | AP.PageStart
The question is: How do I match different fields from one table on one field of another and make it return another field (the ID)? Some references are too horrible to match, but I need as many as I can get.
I can imagine two queries would give me the bulk:
A match in [Title] AND [Year]
A match on ([SourceTitle] OR [AbbreviatedSourceTitle] ) AND [Volume] AND [Year] AND [PageStart]
I understand that I have to make use of the Like "*"&[value]&"*", but how do I make it return the matching ID?
I am trying to map certifications done by colleagues in my department.There are 4 certifications and I have which I have pulled out from the Certifications tables using individual query for each certification.Now, I want to add "Certification-Name_Certified" col which will have "yes" or "no" values for each certification to the master data of the department personnel as it only have unique records using a query.
View 4 Replies View RelatedI am trying to write a query that gets all the telephone hours from a worker done under supervision in a town (qry_svhoursbytown). I have a table that has the workers details, including town (Crisis_support_workers), then another table that has what hours each worker has done (Supervision_Hours). The town is selected from a combo box on the form (frmSearch), under the heading �total hours by location�.
I try and select Bathurst then press recalculate results and in the text box next to supervision hours, it says 66, but if you look in the Supervision_Hours table, there is only 11 hours for the workers that are in Bathurst.
In the query, I have the sum total of the hours field in the Supervision_Hours table, the Town field from the Crisis_support_workers table with the total selected as Where and in that criteria I have [forms]![frmSearch]![ComboTown], then I just have the town field displayed.
What do I need to change to get it to sum correctly?
I have attached the database below so people can take a look.
I have a question regarding counting of text values base on their status and using that result to a calculation.
Say, I have a table of Demand of Positions, wherein, I have a specific Job Title for a certain Department that have number of workers needed (demand quantity) and a table of candidates for that job title and their status, say, Arrived, Visa Processing, Visa Applied, Visa Issued, and With Ticket.
What I would want is to make a summary out of the two tables, where the query will count how many candidates are there in that specific job title and have a field of status say, field of Count of Arrived, Count of Visa Processing and etc., and a field where I can add all of the count of candidates per status and deduct the result to the demand quantity where that field would be named Balance.
The problem is that the status varies on every candidate on that specific job title because the status field is used to track the progress of each candidate and this scenario will make the query blank because there would be no such record due to their status.
I tried making a summary following my requirement and you will see that in the attached file together with the SQL code of that query that the balance field value is blank.
I have a field called density which needs to be updated to show either 10, 20, 30, 40, 50,60, 70 or 80 depending on a number of variables, for example: If market location is 'hot' and unit type is 'house' and discounted is 'no' then show '10' in the density box.
or perhaps:
If market location is 'cold' and unit type is 'apartment' and discounted is 'no' then show '20' in the density box.
I have tried all sorts of expressions and queries but have really reached the limit of my know how and can't solve it. Is it even possible to do this in Access?
I have a combo box which gets its values from sql server using a query which is called "get_query_reason", which works fine. Now I want to update combo box values based on a user selection, st string. Have written the code, but does not work:

I have 2 form controls one a combobox and the other a text box. The text box select the site (txtLocation) where the user can enter part of the name of the site and all sites with those characters are returned. I've done this by adding:
Code:
Like [Forms]![frmSearchDB2]![txtLocation] & "*"
into the criteria on the Site field in the query design editor.I also want the combobox to have an affect on the query. I want it to query on user status. However if the combobox reads "All Users" I want it to return all status's and all null values. In the criteria field I put:
Code:
iif([Forms]![frmSearchDB2]![cbxUserStatus] = "All Users",like "*",[Forms]![frmSearchDB2]![cbxUserStatus])
It kind of works but no null values are pulled back. Should it be an expression?Do I need to do it in VBA?
I have a table listing about 20 elements as field names eg FE, CR, NI, TI and so on.
I have built a form which has a combo box listing these elements by selecting "fields" in the property settings of the combo box & next to this combo box i have 2 text box's where the user can input Min & Max values to pass on to the query.
E.g., FE (chosen from the combo box) value between (Text box1) and Text box 2.
I can run the query to give me values between the 2 text box's by using the following formula in the criteria (Between textbox1 and textbox 2).
The issue i have is to be able to select the element from the listbox, input the min & max values identified and be able to pass this to a query so the query can filter based on the field and values passed?
I have a form (DropDown form) that has 3 drop down fields, you select your values from the drop downs and you would push a command button that runs an event procedure which runs a query (DropDown qry test). The user should have the option of picking any combination of fields to filter by. Or no combination, which would return all values in all fields. So I am basically using the form as parameter's for the query.
The problem I'm having is that my query is returning values for one field AND values for another field. Even if the other values selected are not in the same record. It's not combining the fields together to filter. For example: you pick a Project name and Supplier name, the query will return records that have the project name you selected but it will also return records with the supplier name you selected that have a different project name.
I've attached screen shots of the form and the design view of the query (the screen shot cut off the last column name. It is meant to say "Expr3: [Forms]![DropDown form]![Combo7]").

i'm creating a search form giving the end user a range of controls to use when filtering/searching data. See the image.But, i think my range search (using the textbox) to put in a lower and upper limit...is preventing this from working. In fact, when i put data into all the controls, no data pops up in my subform.
My query data source can also be seen...showing you how i've handled teh null entries. (i need to put in a null 'handler' for the two textboxes?)

View 1 Replies View RelatedI have a table of records, which has within it two date fields (effectively, a 'start' and 'end' date for that particular record)
I now need to create a query to perform a calculation for each date between the 'start' date and the 'end' date

(The *obvious* solution would be to create a separate table of dates, from which I could just SELECT DISTINCT <Date> Between #04/01/2015# And #04/09/2015# - but that seems like a dreadful waste of space, if that table is only required to generate the above? And it would have to cover all possible options; so it would either have to be massive, and contain every possible date - ever! - or maintained, adding new dates as necessary when they are required. Seems horribly inefficient!)
Is it possible to just select each date between the two reference dates? Or can you only query something which exists somewhere in a table?
I'd like to create a query which will consist of simple SELECT statements as follows:
SELECT [table1].[field1], [table2].[field1], [table2].[field2]
FROM table1 INNER JOIN table2 ON ([table1].[fieldX] = [table2].[fieldX]);
The challenge arises b/c instead of joining on equal values, such as the following:
[table1] INNER JOIN [table2] ON [table1].[field1] = [table2].[field1]
I would like to join based on equivalencies, such as:
[table1] INNER JOIN [table2] ON [table1].[field1] = 34 is equivalent to [table2].[field1] = 2;
I do not know the proper syntax, so this is where I need help. I tried to search online without any success.
I appreciate your help in advance.
I have two tables with dates. Between (!) every two following dates in table1, I want to know the number of dates in table2. How do I write an SQL query for this? The tables I have are up to a few hundred records in table 1 and a few thousand records in table2. So to prevent that this takes hours I need a fast query.
To explain the query I need, for example:
table1
01/01/2014
15/01/2014
17/01/2014
30/01/2014
table2
01/01/2014
02/01/2014
05/01/2014
17/01/2014
18/01/2014
20/01/2014
21/01/2014
25/01/2014
So the answer of the query would be 2,0,4.
Explanation:
Between 01/01/2014 and 15/01/2014 in table 1 there are 2 dates in table2 (01/01/2014 is not included between the dates)
Between 15/01/2014 and 17/01/2014 in table 1 there are 0 dates in table 2
Between 17/01/2014 and 30/01/2014 in table 1 there are 4 dates in table 2
