Forms :: How To Ensure Unique Data Across 2 Fields
Dec 17, 2014
What is considered the right approach to ensure a record entered in a form is unique. For example if i have a field:
Brands. Flavour
Walker. Ready salted
Smiths. Cheese and onion
Doritos. Ready salted
Walker. Ready salted
So what is the best way to ensure the third entry is fine as whilst ready salted already exists it doesnt exist for doritos but the fourth entry would pull up a msgbox refusing the entry as it is a repeat of entry one.

Can someone please help me?
I have a combo box on a form that the user can select a player name.
Under the combo box I have a label called "Show me information about selected Player: that once clicked takes the user to another form which has all information about the player that was previously selected in the combo box.
Everything works fine UNLESS the user forgets to select a playername from the combo box and clicks on the label anyway. Obviously no player name was selected so a blank form opens which is a problem!
How can I ensure that a player name is selected and prevent the user from clicking on the label below without having previously selecting from the combo box?
If anyone can please help I would appreciate it so much.

I am designing a Web Database with a bound form to a submit table.
On the form, I have a combo box with selections that should influence the value to be displayed in a textbox also on same form.
For instance the combo box for Staff Name contains list of all Staff and I want the textbox to automatically display the level of the staff that was just selected in the combobox.
I know how to get this done using a combobox but my boss insists that the level should be automatically displayed in the textbox once combobox selection is done.
Using the combobox for level, I used the select statement in the RowSource property :
SELECT Staff_List.Level, Staff_List.Staff_Name FROM Staff_List WHERE (((Staff_List.Staff_Name)=[forms]![frmtest]![cboStaffName]));
I am in a dilemma of how to replicate this for the textbox because textbox only has control source and no RowSource where I can put this select statement.
Also, I will still need to bind this textbox to the submit table with the column name "TxtLevel" in the control source
Please see attached sample access db.
Also note that I cannot use action queries or VBA because it is a Web database and not a client database.

Is there a way to format a memo field to ensure that sentences begin with capital letters. There might have been something in the strConv function, but it seems my hopes are dashed?

I tried and failed to get this to work using a multiselect listbox..I have a list of departments in tblFunctionalArea...My main table is tblStatic..I want to be able to for each record select multiple departments affected by a record and store them in the tblStatic.After looking around i couldn't find many people successfully maanging to store listbox values in a table...
I decided to create 5 fields in tblStatic and in my form create multiple combo boxes cboFunctionalArea1, cboFunctionalArea2 etc etc which are bound to these fields.I want to be able to ensure the list for any combo box requeries and takes out any selection in the other boxes.
I have this working in a strict cascade fashion i.e. in cbo1 all dept's visible, in cbo2 it takes off whatever was selected in cbo1 etc. But if someone then jumps back and deletes the content of cbo3 then the whole thing breaks or if they amend in the wrong order it breaks

I have a query that creates counts of fields based on the data in other fields, basically it tells me that in a table there are two entries with value ABC????? and three of DEF????? , the query works perfectly.
When I create a form to display this data and base the form on the Query I keep getting a message box asking for the ID (key field) from the base table.
If I type * in the box (to denote all values) and press enter I get the results expected.

I'm working on a database that has to be done in Access and in coming up with a unique ID for each worker I want to take the first letter of the first and last name and the last 4 digits of their social to create the UID for the table. So for FIRST_NAME:Homer LAST_NAME:Simpson with SOCIAL:123-45-6789 his UID would be HS6789. Is there a function within Access that would allow me to do that, or is that something that's just too advanced?

I am working on a database of biological samples and test data. A problem is that many times the same subject has multiple ID's. For example, one subject may have the ID "ID234" but they previously had the ID "Sub84" or something like that. I want to be able to have 3 or 4 fields that have ID's for a subject, and I don't want a single one of them to be repeated. So I have column a, b, c, and d, and I don't want to have one record to have the same ID in column a as another record has in column d and so on. All I have been seeing is a way to make sure all of a, b, c, and d are unique combinations, but I want none of the fields to be repeated.

I have a large query that has information from accounts sorted by date, account repeat but they are always associated with a different date. I'd like to create a report where each date has it's own column with an associated field displayed as the information in the column. However, as data is added to the table I'd prefer to do it without having to make a query to filter each date each time information is added.
The information is added in bulk with all the same dates, so ALL accounts (excluding newly opened accounts that may have no information with a certain date) should have information for each date - there will not be single accounts with their own date. For example: An account numbered 12345 with data of 57% on 1/2/13, 63% on 6/2/13, and 89% on 12/2/13. I'd like each of the dates to have their own column, with the account numbers as the row and the percent data to show under the date they are associated with. how to manage this in a report, or if it is possible.

I have this basic question (obviously not so basic for me): how to pull out only unique records from two fields.
More details - two fields with names of competitors in a tournament (Winner or Loser) and i need to build a query to have all players names participating in the tournament regardless if they have won or lost in one list.

How i would best combine values in a table to produce a 'primary key id number.'
For example: the first letter of a city in the ID and the next number available/auto number - Portsmouth -> P233
I know i can create this in a query however i want it as the unique ID for that record entry in a table. If that doesn't make sense i can try to elaborate some more.

Any way on a table that I can have a unique identifier over two fields? E.g.I have a login ID and a Domain field in a table with sample data below.
Login Domain
John Test
Jane Test
Fred Live
John Live
The login names need to be unique to the domain so the integrity cannot be breached. This has to fit into one table (although the domain is actually being pulled from a look up table so is in fact a numerical value) for ease of form creation.

I have a MS Access 2000 database with 136 data tables in it. What I would like to do is execute a piece of VBA code which will list for me in another table, (for example: Field1: TABLE NAME Field2: FIELD NAME 1 Field2: FIELD NAME2 etc), starting left to right, how many fields would have to be combined in each table to represent a unique record.
For instance:
TYPE ID TEXT
1 1 "Cats"
1 2 "Dogs"
2 1 "Rabbits"
In this example a combination of the fields TYPE and ID give a unique record.
Any help most appreciated.

I am undertaking an analysis of corporate mobile phone data based on data from the phone provider. The base data consists of a number of monthly text files at transaction level for voice calls, data usage, billing/tariff information, international calls/transfers etc. I have set up VBA code to import the text file data into a number of Access tables.I would like to have a way of joining these tables but the only common field is the phone number (a text field with the groups of numbers separated by hyphens).
I confirmed that joining the tables on the phone number text field does not work.My idea was to create an additional table with just one row for each phone number and link that to the other tables by the ID in the new table. I was able to create this table [PhoneNumbers] (by creating a totals query of the phone numbers from the main call transactions table, I then dumped it into Excel and then imported it into a new Access table with an auto-generated ID column).My problem / challenge is how to get the ID column from my [PhoneNumbers] table to appear in each of the other tables so that I can join them effectively. In the Excel-world, I would have used a vlookup function.I even thought of performing this as an interim step in Excel but there are too many records / rows in some of my tables. It seems that the dlookup function is not what Im looking for and even if the IIF function is suitable, I cannot get the syntax to work for me.

I have a client database that has recently had multiple duplicate entries. I need to reduce or negate this erroneous activity. I have a client table where I record amongst others, the following;
key
[christian_name]
[family_name]
[dob]
......
I believe that to prevent duplicate entrie via form I have created an additional field called "unique" given it as a unique index which I want to have populated with the joined fields first_name & last_name & dob (IE johndoe01/01/90), and then as user enters a new client it wont allow a duplicate.
However I need to fill all the existing customers (3600+) with the relevant joined existing data. If I create an expression I can cajoin the fields in a select query but when I try to make an update query the same syntax comes up with empty fields.
select query sql that worked to show field ...
SELECT divers.christian_name, divers.family_name, divers.dob, [christian_name] & [family_name] & [dob] AS Expr1
FROM divers;
update query that was empty ..
UPDATE divers SET divers.[unique] = [christian_name] & [family_name] & [dob];

I have a calculated field which sums the quantity field for all transactions by the part#, lot# and location. (A part number could be in several different locations and lots and are treated sperately - if they are in the same location with the same lot number they are summed).
To add quantity the user enters the data using a form. To issue (subtract) the user uses a minus number (eg -20). The calculated field sums all these and outputs the current total.
How can I make sure this is always positive.
Ie. When the user does an issue the qty they specify will be less than or equal to the current total according to the sum calculation.
Thank you for any help

1. I have a database (see attached) with three tables all of them with the same fields. The first three are numbers (InCo_No, Proto_No, Year_No). Each of these fields (numbers) can be the same in the other table(eg. Year_No), but the combination of the three cannot be.
How can I prevent the entry of a duplicate combination of these three fields?
2. I want to have a form to fill the three tables separately, depending the values in the other fields.
How can I do this?

I am developing an Access database, and using the Access 2007 Developer Extensions to "compile" it into an installable program which includes the freely distributable Access 2007 RunTime, for users who don't have it already installed.
I am planning on charging a subscription fee to use my Access database. Are there any existing method for handling making sure the user's subscription is still active, and if not, either locking them our or preferably making everything read-only? If there aren't any existing methods anyone can point me to, does anyone have any ideas?
I plan on being the person who installs the application the first time, however I'm sure instances will come up where I instead mail the user a CD for them to install.
Regardless of whether I complete the first install, I'm not interested in going to each users' location periodically regarding the subscription.
I'm more interested in going the route of the user typing in some type of registration code, which is validated for read/write access for a period of time.
I don't want to rely on the user having an internet connection, but if they had one, I could certainly go the Microsoft model (try internet verification, if it goes wrong or there isn't a connection, have user call in.)

I have a form with two fields in the header meant for filtering the form data - SelectAtty and SelectClient. The query under the form is restricted based on the values selected. I also have a "button" that if clicked should filter the records (probably unnecessary but I thought it would be clearer for the user). I'm seeing two issues. Sometimes when I select a value - it doesn't appear to apply it to the query at all. When I add msgbox statements to try to see what is happening, the problem goes away (weird right). Also I run into a "no current record" error when it requeries. Mostly this seems to happen when I have two events that fire in a row and both requery. The event procedures are below and you can see where I put my debugging msgbox statements.
1. No current record fires consistently on the filter image click and (I think) always when it requeries twice (like I changed the value and then clicked on the filter).
2. The fact that sometimes the selections are picked up in the query and sometimes aren't I have no good pattern for other than msgboxes seem to actually fix it - as if it forces access to look at the values and they they show up.
Private Sub FilterImage_Click()
MsgBox "filter: " & Form.CurrentRecord
MsgBox Form.RecordSource
[code]....

I use Cognos to pull raw data from Oracle. I take this data and put it into Access 2010 tables to then run queries. Because the people creating the data in Oracle are often slow, I run back data to catch missed information, typically two months. For October, for example, I'll run October and also September and August.While I have new data, I also have a great deal of duplicate data. How can I ensure that I append only the new data and exclude the duplicate data?

However, if there is no data for the criteria I am entering, I get a blank form. Is there anyway to have the fields of the form show even when there is no data?

Hi
I have a table called SWAPS which contains information on each user and the different equipment he has been issued. Query at the moment contains 5 fields
Payroll, Surname, Firstname, Mobile No and Date sent.
SQL for this query is as follows
Select Swaps.PR, Swaps.surname,swaps.firstname,swaps.[mobile no],Max(Swaps,[Date Sent] as Lastdate
From Swaps
Group by swaps.pr, swaps.surname,swaps.firstname,swaps.[mobile no]
Order by swaps.pr;
Now when I run this I get the results I want by date so I get
123456 Smith Fred 0788411025 12/3/8
456789 West Bob 012555447854 13/1/8
So it correctly ids all the last dates for me as I want to see the latest issue date for that user. Now I want to add in another column to this query which contains the serial number of the equipment issued and heres where the problem lies. If a user has been issued more than 1 piece of kit, I get all the serial numbers irrespective of date. How do I get it to display the serial number for the latest date?
Thanks
