Need Help With A Calculated Expression/data Table.
Mar 30, 2007
I am very inexperinced with Access, please be kind.
My problem is that from the form view the simple division of 2 #'s are placed in the correct text box I selected, but I am unable to get the value to enter into the data table. Please help.
I have two email addresses in a table one personal and one work and a question asking which to use, I have a query running from the table and have an IIF expression creating a field which looks to see which one to use (that all works fine !) anyway my client has now asked for an extra field in the query which combines the two email addresses, as in aaa@homedomain.com;bbb@workdomain.com so that I can run an email to both addresses at the same time. fraid I just can't figure it out ! I'm sure it's obvious, I can't find a similar question posted either, I've tried the expression builder using AND for the two email addressses but just end up getting -1 in field when I run the query, not the two email addresses separated by a ;
Hi all ... been awhile since I have had to create a database so I have gotten a little rusty. :eek: I have a form where some of the fields I have formulated to calculate an amount. Example... =[GrossAmt]*[FeePercent] This is calculating into the form correctly but not writing to my table for that field. What am I doing wrong or missing here?
I have a textbox on a form that displays a calculated number with regards to input from other text boxes.
I need this calculated number to update to a corresponding field within a table.
I have a button that updates the information, but the calculated field will not update.
I have an "=" expression written that does all of the calculating. When I put this in the 'control source' it calculates and displays on the form perfectly, but will not update the table. If I change the control source to the field within the table and then move the "=" statement/expression someplace else....the field is blank on the form, but I can manually input a number and it will update to the table.
Hi Guys, I don't know Access very well but I know enough to generate a 2 dimensional database. The problem I have is that I have been asked to look at a travel agents database to create some additional letters. The problem is that they use a form which has an underlying data table called customers. When they create a record in the form all fields in the customers table are filled in except those on the form which derive their data by calculating two or more fields i.e Date Due is [Date of Travel]-70 (days), Balance Owing is [Cost]-[Deposit]. None of these derived fields fill in their corresponding fields in the customers data sheet.
I would welcome any ideas please. Thanks in anticipation
Hello all, I'm quite new to Access. I've read many Access tutorials and site but I have yet to found the solution for my problem. So here it is (pardon my english):
Field AmountTotal is =(Nz([AmountSubTotal])+Nz([AmountSH])-Nz([Discounts]))
I manually input AmountSubTotal, AmountSH and Discounts. I expected an automatic calculation for AmountTotal.
In "Form view" I get the result of AmountTotal that I wanted. But the calculation result doesn't get recorded in my field data table AmountTotal. It just shows blank.
How do I record this automated results into my original table?
I've got a Table with a string of data delimited by an "*". The first part of the string before the "*" can be variable in length, so if I use a LEFT expression to break apart the 2 parts of the string on each side of the "*", my results are incorrect. In MS Excel, I can use the following formula to solve the problem:
=LEFT(B6,(FIND("*",B6)))
You are just substituting the number of positions with a Find command that looks for the "*", and returns anything left of the "*". Unfortunately, the brilliant programmers at Microsoft, once again, don't have an Excel function in Access. how to recreate that functionality in a table in Access?
I having a problem with the expression builder in a table.I got a lot of fields with dates and I what a calculated field so I can see if any of the dates are newer than 7 days.I have been trying this formula:
I've now since moved everything into one table but i need formatting of my calculated field (I'm new to all this).
Below are the 3 expressions working independently of one another, I just need them combined in to one if possible. As I am getting an "invalid syntax" error or "too many arguments" when I try to get it working
PHP Code:
0.5*IIf([Type]="Offlist" And [APP_LINE_OFFA]>3,1,0)+0.2*IIf([Type]="Offlist" And [APP_LINE_OFFB]>2,1,0)+ IIf([Type]="Offlist",Abs([EP_DETAILS_OFF]*0.15+[REF_DETAILS_OFF]*0.15),0)
i have a total in an invoice with is a tabulated form with totals in the detail footer I want to post the calculated total (control) to a table. How ia this done.
What I'm trying to do: I have created an unbound field within a subform's footer to calculate the average of the displayed record values. The subform is in datasheet view. The records are returned based on a query with a relationship between two tables. I need the calculated data (which I currently have displayed on the main form) to populate within the master table.
I can't figure out how to automatically do this. I created a simple command to get it there, but I'd like the user not to need a button to display a calculation.
Main form based on TableA; subform based on TableB.
Here's how I have it set up (Btw, I suck at SQL I just figure this is easiest to read):
Query SQL looks like this: SELECT tblB.Field1, tblB.Field2 FROM tblB.Field1 INNER JOIN tblA ON tblB.Field1 = tblA.Field1
Main form: unbound txtbox = [Forms]![frmA]![subfrmA].Form.[txtAvg]
The field that is averaged is tblB.Field2. There are potentially a bunch of records displayed in the subform.
I need that [txtAvg] field to save to TableA. My command button is simply Me.tblA.FieldName = Me.unboundtxtbox. I'd like to do away with that.
I tried to use the on current or on load event for the main form; but the calculated field value is 0 until it calculates it. It seems like there is a short delay before the value shows up on the form at which point the on current or on load events don't pick up the calculated value; just the 0 that is initially there.
I've read over and over that calculated data is bad, that's fine with me... but here is my dillema...
I have four fields that interact with my calculation in a single form. There is only one table in the database.
AmountF (The stored data in the table) (amount financed) FC (calculated by =[amountf]*.25) (finance charge) Amount Paid (used in calculation of total due) total due (calculated by =[amountf]+[fc]-[amount paid])
The math already works, everything works. I can choose to print the form and it looks great. However, I would like for it to (when I'm done printing the form) somehow save the total due data to the AmountF column in the table. AmountF is in the same line as all the other information, so I would like it to not create a new record just update the old one.
All four of these fields have a text box in the form for themselves.
I am trying to change the data type of a field in a table from calculated to something else. It gives me the error "this data type cannot be changed once the field has been saved"
Currently I have a calculated field in my table; however, under certain circumstances I need to change the value to another value which is not related to the calculation. I understand that the calculated fields are read only (why is that?), so I was wondering if there was any way to change values within a calculated column without actually changing the expression itself.
I've can do this on excel but don't know how in Access. I'm calculating bonuses. My table has salaries, and my query simply multiples each salary amount by a % to get the bonus amount. But I need to calculate adjustments to the bonuses using the sum total of the bonuses my query calculated:
Salary (from table) Bonus (calc'd by query) Adjustment (to be calced)
100,000 1,000 Sum of total bonuses/salary*4% 90,000 900
How do I capture the total of my calculated bonus column to use to calculate the adjustments in my right-most column?
I tend to work with large amounts of data (extracts from company systems) and I create a lot of Access/VBA based tools to automate processes.
I have an annoying error which has always appeared but I don't understand the root cause of it.
When viewing a query, if I filter, I get an error message pop up (though after clicking through the error I can still use the filter function):
"syntax error missing operator in expression 'name of field'".
This seems to happen when I add several calculated fields. Here are some examples of the conditions and calculated field formulas I'm using in this current one:
Conditions: <>"CINEMATIC" And <>"SFX" Not Like "*_ZZ*" And Not Like "*test*" And Not Like "EP_*" [Forms]![FRMscriptPrintReview]![selectLangCombo]
I get the impression that its more of a bug with Access as the formulas aren't complicated really but need confirmation on this and if there is a way I can avoid it.
I have what is probably a stupid question but I've been struggling with this one for a while. I have an ordering database which has an Orders table (containing Order ID, Date, Supplier etc) and an Order Line table within which I have a combo box for Product name, supplier, price, VAT rate, Line price etc. At the moment, I have the order line table as a subform within the Order form (run from the Orders table). The problem I'm having is the subtotal and total fields. At the moment these are in the Order Line table as I cannot figure out how to get these in the Orders table. In summary, can I make a calculated field in one table that calculates values from another table (linked by Order ID)?
I know it is said that you should not store calculated data in tables so I need some input on how to go about a problem I am having.
I am creating a DBase with some aircraft info in it. The DBase will be around for awhile so I plan to implement so sort of archiving later on.
The problem is one piece of info I am tracking is flight hours for the aircraft along with hours on certain components. I have a table with info pertaining to each aircraft by number (1 record per aircraft) one of the fields is total current flying hours. I have another table that has individual flight info including number of hours per flight. I want to add the individual flight hours with the total flight hours to get a new total flight hours. Easy with a query but if I get rid of old flights then how will you add them in the query. The only thing I can think of now is to save the newly summed number in the table which is supposedly taboo. Same with the components if it is on the aircraft during the flight it needs to get the new flight hours on it also .
Sorry if this is trivial but any ideas on how this should be done would be great.
I need to make a calculated field show up on my table. My database is for technicians at work to log their hourly health checks. I have a field on form "Health Check" called "HC_ID" that I automatically bring over to the next form called "Channel_Scan_Form" with the control source property. I would like the data from this field to copy to the accompanying table called "ChannelScan_Table" from this "Channel_Scan_Form". I have tried to place the code in several different events on the property sheet but haven't had any luck bringing the data over to the table. I'm just starting to play with databases, plan on being here for a while and hopefully contributing in the future.
I generally use Cognos for my queries, so the overly user friendlyness of access is confusing me and im not proficient enough in sql to just go in and edit the code...
How do i generate a query that groups data in unique ways in the result, but does not change the data in the originating table.
For example:
I have the column tbemployment.dept . In a crosstab query i want everybody that isnt tbvoter.dept='BELLS' to be counted as 'other'.
In Cognos i would do this in the 'data definition' window for that field and use 'if (tbvoter.dept<> 'BELLS') then ('other') else (tbvoter.dept)'
My employer is using Windows XP Pro and Office 2003 (a few machines have Office 2010, but not mine). Furthermore, the machines are running the Japanese language OS, which has caused some comparability issues with my English XP/Office 2003 at home.
I have a form containing an unbound textbox, with the name MIS. The form's Current event has the following code:
If IsNull([[ResignationDate]) Then MIS = DateDiff("m", [NichiiGakkanStart], Date) + Int(Format(Date, "mmdd") < Format([NichiiGakkanStart], "mmdd")) ElseIf [ResignationDate] > Date Then MIS = DateDiff("m", [NichiiGakkanStart], Date) + Int(Format(Date, "mmdd") < Format([NichiiGakkanStart], "mmdd"))
[Code] .....
The calculates (correctly) the Months in Service of the employee who's information is being viewed.
Now, I am trying to create a report which lists the employees by work locations. The above , and other calculated information, is to be displayed in the report.
I used the wizard to create the report, using data from two different tables (employee & location).
I need to display the calculated information above for every employee at every location.
I am just learning how to use Access and have created a basic form. I am stuck though on getting my form to calculate the Age (from Date of Birth) in Years and Months.
The info on this forum I have tried the following Expression:
=DateDiff("yyyy",[DoB],Date()) & " years and " & DateDiff("m",[DoB],Date())-(DateDiff("yyyy",[DoB],Date())+Int(Format(Date(),"mmdd") & lt;Format([DoB],"mmdd")))*12 & " months "
But my problem is that it tells me:
''The expression you entered contains invalid syntax You omitted an operand or operator, you entered an invalid character or comma, or you entered text without surrounung it in quotation marks''
Can anyone let me know what error I've made and how to fix it? It would be much appreciated. Thanks

I'm facing an issue when I'm creating a Data Macro After Insert in Access 2010. In the value for the SetField, I use the expression builder. I wanted to use the DateAdd function but it not showing, also I cannot see my user define function (Module).
This behaviour seem to occur only in the instance of Expression Builder while in the Data Macro, everything is fine anywhere else including macro.
