General :: 2 Fields From Separate Tables Needed To Create Calculated Field?
Aug 19, 2013
The interface being used is a main form with various tabs and a subform on each of these tabs.
There is one field ('max power density') in my database that is calculated using 'Max Rated Power' and 'Cylinder Capacity' however these are in different tables and subforms. The 'max power density' and 'max rated power' are in table and subform 1 but 'cylinder capacity' is in table and subform 2. Is it possible to keep them in separate tables/subforms and still calculate the field?

I have a notes field in the customer table that is a memo field. An example of one customer's notes field data :
<div>20.3.14 Ordered 2 cartons</div>
<div>4.3.14 Ordered 2 cartons</div>
<div>18.2.14 ordered 1 carton</div>
<div>30.1.14 ordered 3 cartons SCENTED wipes</div>
[Code] ....
I want to extract the date to append to a date field in a "Calls" table and the comment into a text field in the "Calls" table. Is there a way I can do this via query or code?

Access 2010 database.
I am trying to get an average from several numbered fields, which some may occasionally be blank.
=Nz([JanUS],0)+Nz([FebUs],0)+Nz([MarUS],0)
I get an error message that says "The expression =Nz([JanUS],0)+Nz([FebUs],0)+Nz([MarUS],0) cannot be used in a calculated column. This is a hypothetical expression being used.
The real expression is ...
([GC A1 - 2]+[GC B1 - 2]+[GC C1 - 2]+[GC D1 - 2]+[GC E1 - 2]+[GC A2 - 2]+[GC B2 - 2]+[GC C2 - 2]+[GC D2 - 2]+[GC E2 - 2])/10
This expression works great until a field is left blank, and then the average box is left blank.
The fields I am trying to add are Long Integer. Would that affect it?

All,
I have a quick question that could lead into a longer one.
First off, I am trying to associate tests with a course a student is enrolled in. Would it be better to add a column in the courses table and have a comma separated list of all tests associated with each course or would it be better to create a separate table that has a column for the course and another column for the associated test with that course?
If comma separated fields would be better, how would I handle that in forms? How does one parse that field?
Thanks!

I think what I want is:
1 table(1): record of people & contact details
1 table(2): list of events with check box's with the names of people from the other table
1 report: listing how many events people have attended.
When I add a new person to table 1 I want a field to be added to table 2 in the form of a checkbox, also when I delete this person I want this field to be deleted in table 2.how to make this an automated process.

I have 1 table that I duplicated to make 3 tables total. I did this b/c I am trying to create separate columns from the same field and table. The field is Workorder. Each workorder list the workorder number followed by a dash and then code. I am wanting to put all of the workorders with the same code in it's own column.
I have 5 codes that i am searching for. The first column list the workorder and a code (123456789-AD). The second column (123456789-BC). I'm good to this point but my problem occurs next.
The third column i am trying to put 3 types of workorder and it's code in the same column. As follows, (123456789-CD, 123456789-TC, and 123456789-PTC. However, when I do this it takes the results from the 3rd column and applies it to the 3rd column but also the 1st and 2nd column. I tried a UNION query and unless I am doing it incorrectly it does not work.

Hi,
I have two tables:
Table A provides total sales volume of the UK shoe market from 2000-2007.
Table B provides the sales volume of different shoe manufacturers from 2000-07.
I want a third table created, called Table C. This should look exactly like Table B but instead of sales volume it shows percentage sales that are calculated by using the figures in Table A and B (i.e. [sales volume from Table B/total sales volume from Table A] * 100).
Could someone point me in the right direction please (assuming that such a table can be created, based on a calculation of figures in other existing tables).
Thank you.

I am new to Access and was wondering if there was a way to parse the data from a field into two fields.
I have a field named tName which contains both the first name and last name of a person.
How can I get the corrosponding last name into a new adjacent field called tLastName (this field doesn't exist yet)?
Thanks so much in advance,
Paul
P.S. What if the the person doesn't have a last name? or if they included a middle initial?
I know, it's messed up. This DB has a bad setup.

I am trying to create four tables: Company, Contact, Activities, and Opportunities.
I want them to relate hierarchically. A Company can have many contacts, contacts can have multiple Activities and Opportunities. But you can't have contacts without a company and you can't have Activities and Opportunities without having a contact. I want all PK's in all tables to link to one another, that you cannot create one without the other.
How I can do this in Access 2010?
YYMM00000-000000-A0000
CompanyID-ContactID-ActivityID
or
YYMM00000-000000-O0000
CompanyID-ContactID-OpportunityID

I am using calculated field as a data type in access 2010.
They are working fine.
However, I added a new field and now the final calc won't work.
I have Subtotal adding loads of fields together. Works fine.
Then I have a VATunit field which is a double integer, so enter 20 and my next field is VATTotal calculates the SubTotal + the VATunit by doing (Subtotal/100)*VATunit. This calculation is fine and gives me the correct amount.
The next field is a Total field. Which adds Subtotal and the VATTotal together. Howver, the Total is the same as Subtotal. It is not adding the VATTotal to it?

I have two tables of data, each relating to three business branches (branches A, B and C).
Table 1 shows the expenditure of each branch (by fuel, premises and wages).
Table 2 shows a number of units for each branch (mileage, floorspace and sales).
What I would like to do is calculate unit costs, based on the expenditure in Table 1, divided by a relevant unit in Table 2. The catch is that I want to have a third table which allows the user to specify which expenditure (from Table 1) is combined with which unit (from Table 2) to generate the calculated unit costs. I've been able to do this in Excel, and have attached an example. I've also attached an incomplete Access version with the first two tables. Given the complexity of my actual data, I feel this could be better handled in Access than Excel.

I have three columns where A is a number, B is a number and I want to make C = to the greater of the two. i.e.
Col A = 10, Col B = 12 therefore Column C = Col B or Col A = 12, Col B = 10 therefore Col C = Col A

I know that it isn't usually best practise to store calculated fields in a table, but in my situation it is necessary, and I haven't really found a good answer for this after searching these and other forums.
Currently my database has one "Name" field (I didn't make it like this) which might look like this "Jonathan (John) Smith"
Now I also have reason to grab the name like this "Smith, John" for other purposes.
I've set up a form for inputting new people with separate fields for firstname, preferredname, and lastname. I have the calculated fields:
=[fname] & " (" & [pname] & ") " & [lname]
=[lname] & ", " & [pname]
(Later I will add in all the iif's for if there is no preferred name)
Upon finishing the form, the user hits Submit, and I would like to store the concatenated values into the table in their appropriate fields.
I can do this with a SQL INSERT INTO statement but I'd have to add all 25 or so fields from the form, and injecting user input directly into a SQL statement is not best practice either.

Access 2013
I've created a table for a college project and realised that one of my calculated fields isn't working. It doesn't produce an error message, it just doesn't calculate.
IIf([CycleSpeed]<10,[CycleTime]*236,IIf(10<=[CycleSpeed]<12,[CycleTime]*354,IIf(12<=[CycleSpeed]<14,[CycleTime]*472,IIf(14<=[CycleSpeed]<16,[CycleTime]*590,IIf(16<=[CycleSpeed]<=20,[CycleTime]*708,IIf([CycleSpeed]>20,[CycleTime]*944,0))))))

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.

is there any way to put into the calculated field (in expression builder) conditions? What I need is something like
Sum If (Table1.Field1="Y" And CurrentTable.Field2=Table1.Field3)
I means sum how many times there is "S" value in the field1 Table1, but only for records where the field3 in Table1 is equal to the value in the actual table in Field2 (in the actual row).

I am great with Excel but not soo much with Access 2010. I Excel, what I needed to do was very simple but duplicating what I did in Access is not soo easy.I am trying to calculate billings for FSA & HRA. I have set up one table with all the data. I want to add columns to the table to calculate:
1. Is there an account balance-excel formula:
2. If the account is still active
3. If the plan year run out is "active runout" or "runout over"
4. calculate each account type with a rate *count of FSA accounts = total to bill
Here are my excel formulas that for the life of me I can't get to work.
Account balance==IF(V2="HCRA",(IF(AB2-AD2>0,"Available Balance",IF(AB2-AD2=0,"Zero Balance","Negative Balance"))),((IF(AC2-AD2>0,"Available Balance",IF(AC2-AD2=0,"Zero Balance","Negative Balance")))))
Active runout/runout over=
=IF(AG2="YES","Active Runout",(IF(S2=W2,(IF(AF2>$AJ$1,(IF(AH2="Zero Balance","Runout Over","Active Runout")),"Runout Over")),(IF(AE2>$AJ$1,(IF(AH2="Zero Balance","Runout Over","Active Runout")),"Runout Over")))))
Active account=
=IF(D2<$AJ$1,"NO",IF(W2>$AJ$1,IF(S2=W2,"YES","NO") ,"NO"))
Can I have calculated fields that refer back to a calculated field?

I want to use an expression to compare 2 dates and calculate the date of the last set of accounts for a company. The user will enter(DD/MM) of the company year end e.g. 31/12. I then want to compare this with todays date (in another field) to ascertain if the month has already passed in the current year and hence calculate the last year end. i.e. If (current month>company month end), year end date is DD/MM/YYYY (where YYYY is taken from today's date), year end date is DD/MM/(YYYY-1). I am not a programmer and although I understand database theory (from the teaching perspective) I am not expert in developing databases.

I am new to Access and this is likely a very elementary question. I recently created a database to track status of projects including progress and funding. The table contains several fields that record various aspects of funding. These fields are added (very simply) and create a calculated field that is a summation of those fields. The table currently contains approx 60 records. The calculated field functions for 2 or 3 records and will not calculate further. I have tried this in a form as well as a query. The form will change the same number, 2 or 3 records. When the query is run the result shows only the 2 or 3 records. What I am doing that is only reading and modifying those records?

Is there anyway to turn off the rounding function in calculated fields - I need to divide a currency amount by a whole number to calculate the number of full coin bags that will be needed (bags contain different totals according to the coin value) - a whole number.
Then the result is used to calculate how much loose coin will remain.
But regardless of the field type and/or the format, the number rounds when I reduce the decimal places to zero. I need the result to be the whole number and to calculate as the whole number.

We have our access database with a bit of a messy structure?
We use our database to record sizes of our product. I am hoping to improve it by adding the items we have in stock to prevent manufacturing more.
Basically our main database called "Make & Model 1" has a list of various makes and model numbers, each model number lists various information needed to manufacture a replacement part.
Customers order the part and these part details are entered into a table called "Order Detail" What I would like to happen is that when the details are entered a calculated field adds the data entered to a text string. I need to match the text string to the same text string in a table called "stock" as there could be one part that matches hundreds of models.
Basically the "profile" "Colour" "height" and "width" make the string and this is what I need to match and tick a box / populate the number of items in stock. Eventually I would like this to reduce by the amount ordered but lets do one step at a time.
I am using Access 2010

Table1 contain Two fields (3Months) and (6Months)
Table2 contain Two fields (3Months) and (6Months)
the table 2 is the source of a form that will let the user change the numbers. table 1 should change Date1 and Date2 Fields based on the two fields (3months) and (6months) if i want to make a lookup wizard it should be changed manually and if i make a calculated field i can't find other tables in the expression builder
