General :: Unique Values For Two Column Combobox

Jul 18, 2013

Here's my dilemma: I have a table that keeps track of job postings and how many people applied for each posting. So, for instance, I can have 20 people apply for a job posting say....on July 18. On another column I have the shift name for that posting such as DAY Shift. So, I have 20 people that have applied for the Day Shift on July 18.

What I'd like my combobox to show me in just one instance of July 18 in column 1 and one instance of Day Shift in column two. I have tried using the wizard and then going to the properties of the combobox and attempted to edit the SQL statement to use the DISTINCT value to no avail.

Unique Values To ComboBox

Oct 25, 2006

Hi guys,

I've tried searching all the threads for an answer to my problem and I can't seem to find it....

Ok I know this should be simple...

I know to use Distinct and DistinctRow to only show unique records in a combobox but all I want to do is that once a selection is chosen in the combobox to add a record to a subform, it can't be selected again.

I know in some cases you do, e.g. items on an invoice sometimes need to be entered more than once, but I'm listing Skills for Employees and I only want a user to enter a Skill once per Employee (although Employees can have many Skills, I just don't want a User to accidentally put the same Skill in twice or more per Employee...)...

What's the best optimized way of achieving this?

Sorry for my newbiness.

SELECT DISTINCT Areas.ID, Areas.Area FROM Areas ORDER BY Areas.Area;

Forms :: Single Column Combobox To List Values From Multiple Fields

Apr 8, 2013

I have a data base with names, email IDs, phone numbers of 5 types(example quality, security, IT,finance etc) of person from ten different project teams. I created a basic form for the end user to enter values and created fields for each of the person's name, email ID etc based on the personal type( liek quality, IT, finance etc) on each team. The background table contains records of almost 200 people now.

All of these people will be trained for one task and some will be trained for multiple tasks. I know how to make the combo box allow multiple values/selections but, i cannot list out all 200 personal names in the combobox's rowsource/value list. Is it possible to combine all different name fields and list out all personal(of one team), so that the end user can just select multiple names for that team who have been trained and so on. i need to set the rowsource of the combobox to the values of all personal from one team so the team leader can just go select who has been trained and who has not.

Modules & VBA :: Wildcard Search Of Combobox - Lookup Values In Table Column

Nov 19, 2014

I have a form which has a combobox called Task_Ref which looks up values in a table column.

I would like to be able to set the tickbox value of tickbox called P1 to True if the combobox contains the word "test", each entry on the combobox selection may vary such as:-

Test number 1
Yesterdays Test

As long as the word "Test" appears I would like the above to happen?

I was thinking of something along the lines of:-

If InStr(Task_Ref.Value, "Test") > 0 Then
P1.Value = True
Else
P1.Value = False
End If
End Sub

But this hasn't worked

General :: Creating Unique Ordered Number Field With Auto Shifting Values

May 31, 2013

I'm creating a database using existing data from an excel file full of contact details. What I need to add is a queue type system where each contact in the database has a "Place in Queue" number which is unique obviously.

Lets say Alan is number 1, Bob is 2 and Chris is 3. They have these corresponding numbers in the queue field for their entries.

Now what I need to have, through use of a form, is a way of changing Chris from number 3 in the queue to number 1 and thus have Alan automatically shift down to number 2 and Bob to 3.

General :: Inserting Values From Combobox In Table

Mar 6, 2013

I am a newbie to ACCESS. I am stuck with inserting values of combobox directly into a record in table.

I have five different tables(each has only one cloumn) and a complete full_details table(contains 5 cloumns).

I have a simple form with five comoboxes and a save button on it. The five comboboxes are populated from five different comboxes at the time of form load. Now, I want to add values selected from these comboxes in fulll_details table.

My form is unbound. I tried with VBA code, on the save button click, I have written ,

Private Sub save_Click()
CurrentDb.Execute "Insert into Full_Details(Col1,col2,col3,col4,col5) Values ('" & Combo0 & "','" & Combo1 & "','" & Combo2 & "','" & Combo3 & "','" & Combo4 & "');"
MsgBox "Record Saved !!!", vbInformation, "Success"
End Sub

It gives me some error : "You can't reference a property or method for a control unless the control has the focus property set"....

See, above query works fine , if I set focus of one combobox,but it adds only 1 combobox value in full_details table as only 1 column value.

General :: Put Combobox / Listbox Values In A Separate Table Or Not?

Jan 29, 2015

Whenever I create a combobox, Access asks me if I want to grab the values from another table, or if I just want to manually input the possible values.

My question is: is one of the two solutions "better" than the other?

Let's imagine I am creating a Form where I can create a new Contact, and in a listbox (with multiple selections allowed) I want to list the possible character traits, so I have

- Funny
- Annoying
- Smart
- Interesting
- Good-looking
- ...

I think that if I need to store in the Contact records these possible traits, I will have to create a Many-to-Many relationship (therefor creating a junction table) between Contact and Traits.

On the other hand, could I do everything without grabbing values from an extra table and directly inputting the values in the listbox? How would these elements be stored in the Contact record if I allow multiple values in one single field?

General :: Match Sum Of Column Values To Another Table

Jun 12, 2015

I am using access 2010. I have "classlevel" table with 2 columns-Class and Value1 .Value1 column has numeric values that i ll input from webpage (webpage to ms access connectivity).

I want to sum the values of column "Value1" and i have another table-"Volume" which has 2 columns "VolumeLevel" and "Value2". So i want to match the sum that i calculated from first table-"ClassLevel" with the "value2" column in "Volume" table and get the corresponding "volumelevel" column value from that table and there is a third table that will get this volumelevel value.

There is no common column to join these tables.

Classlevel-

Class Value1
Class 0 3000
Class 1 2000
Class 2 300
Class 3 400
Class 4 500

Volume-

Volumnlevel Value2
Vo 0
V1 5000
V2 10000
V3 30000
....upto V10

Answer that i am looking for is V1 as sum=6200 lies between 5000 and 10000 so its V1.

Table 3-

Volume-
V1

Modules & VBA :: Get Number Of Unique Values Without Separating Values That Belong To Same Block?

Dec 5, 2014

I have the following dataset in a table called NR_PVO_120. How do i pick out a number (which can change but let's say, 6) of UNIQUE OtherIDs without excluding any OtherIDs under any fax numbers?

So, if you pick OtherID from Row7 you then also must pick OtherIDs from rows 8 and 9 because they have the same fax number. Basically, once you pick an OtherID you're then obligated to pick all OtherIDs that have the same fax number as the one you picked.

If the number requested (6 for this example) isn't possible then "the closest number possible but not exceeding" would be the rule.

For example, if you take OtherIDs from rows 1-10 you will get 6 unique OtherIDs but row 10 shares a fax with rows 11 and 12. You either need to take all 3 (but that will raise the unique count to 8, which isn't acceptable) or skip this OtherID and find one with a fax that has no other OtherIDs and that isn't on the result set already. My result of 6 UNIQUE OtherIDs will need to contain ALL OtherIDs under any fax the existing OtherIDs are connected to.

So one solution is to take rows 1-6, 26. Another is to take rows 1-4,10-14.

There will be many possibilities (the real dataset has tens of thousands of rows and the number of people requested will be around 10K), as long all OtherIDs connected to all faxes on the result set are part of the requested number (6 in this case) any combination would do.

A few notes.

1.Getting as close as possible to the requested number is a requirement.

2.Some OtherIDs will have a blank fax, they should only be included as a last resort (not enough OtherIDs for the requested number).

my table (NR_PVO_120)
Row OtherID Fax
1 11098554 2063504752
2 56200936 2080906666
3 11098554 7182160901
4 25138850 7182160901
5 56148974 7182232046
6 56530104 7182234134

[code]....

A few sample outputs

one solution is taking rows 1-6 and 26.

OtherID
11098554
56200936
25138850
56148974
56530104
56148975

Another solution is taking rows 1-4 and 10-14.

OtherID
11098554
56200936
25138850
56024315
56115247
56148974

This is for a fax campaign, we need to make sure no fax number is faxed twice, that all people connected to that fax number are contacted under one fax sent.

Generating Unique ID From Combobox

Nov 2, 2007

I would like to create a unique ID number (currently the Primary Key) for a table in Access 2000.

I am using 4 elements for the current manual entry, and want to automate it after I make one selection on the Combo box.

The elements are:
1: The species of the wood I am entering into the inventory.
2: The last two digits of the current year.
3: A ":" as a separator.
4: A sequential number unique for each species of wood as purchased in the current year. This would reset when the year changes.

For example, I can use the Combo Box to select either Ash, Maple, Myrtle or Elm. When I make the selection, I want the system to automatically generate the rest of the ID code.

If I had the sixth piece of Maple for 2007 I would select Maple in the box, then the generated code would be Maple07:006. The next piece of wood might be the fiftieth piece of Myrtle, so it would be Myrtle07:050. On Jan 1, 2008 the sequence numbers would all reset to 001 - so the first piece of Maple that year would be Maple08:001.

Can this be done? It would help me to avoid the problem of skipping numbers when I loose track of the last piece of the same species I entered. Can I do this with a simply formula macro, or would it need VBA?

And can this code ten be used in the Primary Key for that table - and will I need to re-enter all the 300+ pieces I already have in the table?

I had thought this could be done with a 3 field key - but I'd like to keep it as simple as possible.

I have a table with about 700 records in it that I import. In my code I am using Alter table to add a column called BlID. I want to populate each record with a unique number.

My problem is that I cannot think of a ways to loop through this and insert a the date and time in each record.

I am using MS Access 2007.

and if DATE is 09/07/2006 I want PAY PERIOD END to be 22/07/2006 etc

How do I do this?

Kind Regards,

I've been able to get the textbox of the combobox to output the correct format using a custom format but it does not affect the combobox data. Also, I'm not sure how to separate this by two columns...

I have figured out how to reduce down the dataset to get a list of all unique combinations of Column A&B,what formula I can use in a query to sum column D on my table for every unique combination of column A&B. This is a simple SUMIF in excel, but my dataset is too large for excel.

Unique Values

Mar 1, 2007

I have a query that has an Item, ItemPrice, Allocation, and DatePurchased ordered by DatePurchased with only unique values.

I'm using it for a PO Database, when entering items purchased, I have the Item field populated with a items previously purchased, when the item is selected the Unit Price and Allocation Fields are autofilled in with the most recent values from the PO details table.

My problem is if I purchase 10 of the same Items on 10 different dates then the combo box will show 10 of the same Items, because they are not unique values because of the DatePurchased.

What I want is a query to show one unique Item entry with the most recent Purchase Price. I can get a list of unique Items, by only making a query of those and showing only unique values, but as soon as the date is introduced it no longer works, for obvious reasons.

Any help appreciated,

About Unique Values In Tables!!!

Oct 4, 2006

Hi,
I have a situation and i do not know how to handle it.
I am developing an application for a lawyer. In the data base i have the following tables: Files, the people table (that are involved in a lawsuit), and other tables. The problem is the following: in the people table, beside the primary key i have another unique element that is social security number.
In the files table beside the primary key another unique element exists: the number and date of the file (File 1 from 15.02.2006). A lawsuit file can have more law terms: today it has one law term and maybe next week another law term so i must have the same file many times in the table with the same code and another date, but i cannot add the same file many times in the data base because a file has data about one person and the social security number of the person is unique.

If anyone can offer me a solution it would be good.
Thank you!
