Creating A SUM Field

Aug 17, 2007

I feel like this is a stupid question but here goes:

I just created a large database of which a few fields are going to represent "total" fields as they are the sum of a few other fields.

I attempted to build an expression in the "update to" box in an update query but it does not seem to be working. I tried creating a simple addition expression and it tells me that I am about to update XXX number of fields but when I look at the data afterwards no changes have taken place. I am not familiar with how to use the Sum function so it was not working for me.

I'm not sure if I'm going about this the wrong way but if someone could push me in the right direction I'd appreciate it.

Thanks.

Creating A New Field

Jul 3, 2007

I have a first name, last name and a company name on the customer/contacts table. I would like to figure out some way to create another new field that contains either the company name or a joined first and last name if there is no company name. I am sure I have seen this ability somewhere, but I am not sure about how to go about doing it.
Any advice would be great.
Thanks,
James

Creating New Primary Key Field

Nov 24, 2004

I think that creating a new primary key is the only solution to this problem, but I would love to have other input, including potential pitfalls I might encounter in this process.

Here is the scenario: I have spent the past year creating a "survey based" database in my "spare" time at work. The database holds detailed information about nutrition questionnaires given to children over the years that they are in our program. I have based the structure on using ClientID as the primary key. ClientID = each individual's social security number.

We have another database that holds all the client's information. This is the database where any updates are done to their information. I export the client information (firstname, lastname, birthdate, socialsecurity, plus a few more) that I need into excel. Then I import that info into my database on a regular basis using an update/append query.

We started using the database in September and all was going well until a few weeks ago when I imported data and found a name that was entered twice. On looking closer, I found that the person had two different ClientID's. How could this happen...? Well, in our other database, if a child doesn't have a social security number yet, or we weren't given it, the program creates a fake social security number AAA-##-####. I knew this from the beginning, but wasn't aware of any problem. However, I was missing a significant piece of information. When the child finally does receive a SS#, we go in and change the number in the program!!!! At first I was told this rarely happens (I had about 6 duplicates the first time), but today I ran another import and found 90 instances of duplicated names!

There are just over 600 records in the database. Many of these have had information that is unique to this database entered in a related table, so I need to be sure I don't lose any of that data. There is data in other tables that I could import again if I have to.

Here are my options as I see them:

1. Leave the primary key alone and delete the duplicated values with every update.

2. Create a new unique autonumber primary key, knowing I will have to delete relationships and rebuild them. I would leave the clientID field in the system as it is the only way we have to determine the difference between two children with the same names and birthdates.

3. Run quietly away hoping they don't notice the problem until I am long gone. ;)

What would you do in these circumstances? If you agree with my assessment that I really should create a new primary key, what steps would you take to minimize problems both during the process and in the future?

And yes, I wish about 12 months ago, I had asked if the social security number was ever updated, but of course no one thought to bring that up when we were discussing the database design! :mad:

Thanks for your help!

Creating A New ID Field With Logic

Apr 24, 2008

I am looking for some direction on how to approach this.

I have a table that has a field call DocumentID and I don't like it. I would like to create my own.

In the same table I also have 10 fields of data called L1, L2, to L10.

I would like my new DocumentID to be the 10 fields concatenated together, with a period between them unless the value of the field is null.

If this is a query I need to then move the data back to a table in the same database.

Any suggestions on a good strategy/approach?

Thanks

Creating Time Field

Mar 6, 2006

I have a form that has two text fields "Time From" and "Time To".

I can get the current time to show up with either =Date() or = Time(). Althought when I use Date() the time shows up correctly in the field until I click on the field to edit it and then it shows the Date instead of the time until I tab out o the field. But I want the user to be able to pick another time without having to type it in. Kind of like a list box but with a scroll that with either increase or decrease the time.

Also I am trying to get the "Time To" field to be 30 minute higher than the "Time From"

I have tried different things like DateAdd("n", 30, [TimeFrom]) and although it does add 30 minutes when I click in the field it shows the Date and time (3/6/2006 12:30:00 AM) and not just the Medium Time (12:30 AM) even though I have the Conrol and the table field formated to Medium Time.

I'm at a loss.

Help Creating A Populating Field.

Jul 9, 2007

A fellow employee of mine who is self taught in Microsoft Access currently has a database with a form that contains fields labeled name and address. She is trying to set it up so that when she begin to type, it will automatically look up to see if that name and address was previously entered to cut down on having to repeat it every time. She has tried the look up function with no success. She is using a single table as a base. Any assistance anyone can give us will be fantastic!! If I have posted this in the wrong forum or if this question was already answered, I could not locate it and I'm sorry if I am not following proper forum protocol.
Thanks!!

Help Creating A Unique Numbering Field

Feb 20, 2007

Hi all,

I have been trying to incorporate an access DB in to our business for sometime, but keep coming up against the same issue. We have a numbering system for the jobs we do, which was invented many years ago and cannot be changed. It is in the format "month/Year/unique 3 digits" the 3 digits are sequential, i.e. 02/07/123 ... 02/07/124... etc. I will need this all in one field.
So far I have managed to get the month and year (easy enough) with the expression "=Month(Now()) & "/" & Right(Year(Now()),2) & "/"" Now I need to get the sequential 3 digits at the end, however, I am not sure of any way to do this and it has stumped many people. I have a field that is autonumbered, but don't seem to be able to add this to the end of the expression.

If any of you have any suggestions I would be greatful - bear in mind I am only a begginer at this.

Thanks in advance.

Creating An Expression From A Date Field (Help Please)

Apr 8, 2006

I one of my tables, I have a date field (DateCompleted) with the format: mm/dd/yyyy

Now, I want to create a query which would create another field (DateExpected) by using the date in the above table and adding 5 months to the date.

The only issue is that for the new field in the query I want it just to have mm/yyyy format.

For example, if the original date in the table is 04/05/2006, after running the query, I would have a new field 09/2006.

Does anyone know the exact expression I would put in the query? Thanks. The expression would be put in the "build" area.

Thanks for your help!!

Creating Field Names From The Data Within

Jul 6, 2007

Here is my problem. I have created a dbase that takes a download of financial data on a four weekly basis to produce an report for my users. The data always comes across with the same numer of columns but at each four weekly period the date moves on. To show this data in a meaningful way I need to change the field heading automatically, based on the date in the data to show the current Period and Year. The dates given in the download cannot be used as the field names as they are not in the correct format.

1/ Does my post make sense, probaly not.

2/ Can anybody help.

Creating Help Field Icon On Form

May 8, 2006

I would like to create a series of help fields for various text boxes on a form to free up space that is currently displayed in several labels.

Does anyone have an example that will allow me to create several help field icons on a form. Clicking on each individual icon will display a help message for that particular icon? I would prefer to store the data on a table. If I write this, I will probably use a recordset and display the data in a label.

I just wondered if anyone else has any other ideas.

Creating Multiple Records From One Field

Dec 17, 2004

Hi all,

I was wondering if anyone had code to split a field by semicolums, to create multiple records.The field has the first line of address for each property with a particular postcode.
For instance

field name:
PRMF
Craven House; Ample Mansion; WHSmith; Bulevard Terrace.

I want to be able to split fields like the one above with these properties by the semicolums so they become seperate records, but share the same other fields e.g. postcode, city...

Thanks in advance,

M-.

Creating Searchable Field Database

Nov 25, 2014

I've attempted to attach a Word Doc that shows fields I've labeled (customer, date, application & so on). Is there a way to put all this into an Access Document, and create a database that I could search by customer, or by serial #? I've got about 400 of these, but it's all in folders on paper now, would be much easier to do it in an Access database.

Help Creating A Multiple Field Search Form

Nov 2, 2007

Hello, i have a database that simply holds all the information on one table at the moment and what im trying to figure out is how to create a form that i can enter data onto that searches all the different fields at once, instead of one search for one thing and another for another. Some of the fileds are Headset number, gasket number, make, model, engine cc, etc.. so what i want to be able to do is have a form with a text box for each of these fields that then searches the table to narrow down the search results. at the moment i have a search for each, say for one i enter the headset number, it searches and pulls up all records with that headset number, then i have a search for engine cc, but what happens is it searches all records again for the engine cc not following on from the search for headset number so i end up back with a load of records with diferent headset numbers but with the searched engine cc. Basically the search form needs to take data entered into each text bow for each field then the combined results from each, narrowing down the results. can anyone help? in laymans terms!!
Thanks

I'm really not sure how to add this.Thanks in advance.

Creating An Input Field In An Update Query

Oct 29, 2007

My form contains the field Bill_Date, which may or may not be input during data entry. What I need is to run a query (I think) that allows me to input a specific date that will automatically populate all Bill_Date fields that are currently null with the date specified. Eventually this will end up on the front end where a biller will click on a link when they open the db, input the date into the field, and then process another report.

I have absolutely no idea how to even begin and was not able to locate any specific information in Help or here on the forum.

Many thanks.

I would like to know is there a way to create a mask on a form for a currency field? I don't want a user to be able to enter in like 125.145.

Many thanks.

Creating A Form To Search Field In Database

Nov 6, 2004

I have created a form to search a field in my database by running a query. i can only get it to search for direct matches as I am having no luck getting the "LIKE" Operator to work for me. the format should apparently be, like "A*" , this works but i woud like to replace "A" with a variable from a txt box in my form. which will be a combination of letters and numbers

followed what i think is the right instructions and pasted the appropriate bits in the expression builder to tell it where to look but doesnt work
cant fathom out why its not working, it just produces blank queries

Also in the query design page do i need to do anything with the optional "Total" row dropdown menu?

Creating SalesTax Field Based On Checkbox

In my checkbox named Taxable I have the following in the afterupdate

Private Sub Taxable_AfterUpdate()
If Me.[Taxable] = True Then
Me.[Tax] = 0.06
Else
Me.[Tax] = 0
End If
End Sub

This will only insert whole numbers in the Tax field as I have tried several
combinations of numbers. How can I get Tax = 0.06?
