Hello Access experts,
I try using query below to find the unique items in a Field but it doesnt work. Can someone help me with this query?
Thanks very much in advance.
In (SELECT [project_item] FROM [Table1] As Tmp GROUP BY [project_item] HAVING Count(*)=1 )
I have been working on a simple data base for some time now (beginner level) and am still trying to improve it. I would like to do something but before that I would like to have your opinion to know if it is even possible?I have a query QryMainReport:
Start Date/Time
End Date/Time
Employee
At the moment this is what the format of my report looks like (I removed other unnecessary fields):
StartTime----------EndTime---------------Employee
12/06/2014 01:00--12/06/2014 03:00------John Smith
12/06/2014 04:00--12/06/2014 06:00------Jane Doe
13/06/2014 02:00--13/06/2014 05:00------John Smith
13/06/2014 08:00--13/06/2014 08:00------Jane Doe
I would like to do as a report. (Dates would always be from Sunday to Saturday). I am not sure it is possible to do that. I suppose first it would mean:I would have to do a query to separate the times from the dates?I would have to find a way for Access to find the unique dates and unique names?Does it mean I have to use cross tab queries?
Hi all,
I'm fairly amateurish on Access so be gentle.
I need to ask Access to calculate a total number of records but only includes duplicate entries once.
For example: If the field entries were A, A, A, B, B, C, C, D
It would return a total of 4 (counting A, B, C & D only once).
Can anyone advise on how I can do this? My only alternative is to print the database out and cross out duplicates. Not the most interesting way to spend my afternoon.
Thanks!

I have a task of managing hardware assets like desktop, monitor, HDD, routers etc. Each item is marked with a unique ID.
These items could be transferred from one city to another city; so need to track that too.
1. There will be two tables
One (say AssetDetail) will have the following fields
RecordID
City
AssetID
Description of the asset (desktop/monitor etc)
ProductSerialNumber of the asset
Second (say AssetTransfer) will have the additional fields
NewCity
AssetTransferredDate
2. I only want to open a single form :
a) where on the basis of either AssetID or the ProductSerialNumber, I could open a particular record and edit it.
i) if the asset is transferred from city A to city B; then the "City" field value in AssetDetail table should change to "city B"(New City field value).
ii) At the same time, each asset transfer record should get appended to the AssetTransfer table even if the table has an existing record with the same AssetID or ProductSerialNumber.
3. Also need an option to make a new entry to the AssetDetail table from the above mentioned single form.
Feeling stupid today...how can I query a table to find the last five unique records?
Table1:
PrimaryKey
Field1
Field1 may contain duplicates. I need the five latest entered unique records in Field1, and am struggling to write a query for this.
Many thanks to anyone who can help out.

Hi all,
I thought this would be relatively simple task to complete but its proving tricky.
I have two tables with the same data: E1 and E2
E1 has two columns and is as follows
A 1
B 2
C 3
D 4
E2 is similar except for one record '5'
A 1
B 2
C 5
D 4
Now the task is to show those records that do not match...in this instance
E1.Field1 E1.Field2 E2.Field2
C 3 5
Now I've used the find unmatched wizard and this is the SQL:
SELECT E1.Field1, E1.Field2, E2.Field2
FROM E1 LEFT JOIN E2
ON E1.Field2 = E2.Field2
WHERE (((E2.Field2) Is Null));
this is giving me partially the right answer as in
E1.Field1 E1.Field2 E2.Field2
C 3
Anyone else think of some other way?
I have a table with 5 fields:
Build ID Process Product Product_De Operation_
What I am trying to accomplish is as follows:
Each Product can be in the table mulitiple times depending on how many Build ID's it has. So if Product 123456 has Build ID's G004, E818, N005, F813, D024, C879 it will show up one time each for each Build ID. What I want to query is unique Products that are for Build ID's D024 & C879 only and not for G004, E818, N005, & F813.
How can I accomplish this with a query. I am sure I am making this harder than it is but I sure need help.
I just want to know how to manage items in set and individual item. Suppose my product list are
individual items = A,B,C,D,E,F,G,H,I,J,K
and 5 pc set = A,B,C,D,F
and 3 pc set = G,H,K
How should I design the table. Previously I designed the table for individual items and whenever orders for set is placed user had to enter individual items with quantity.
E.g. order is for 5 pc set = 3000
A=3000
B=3000
C=3000
D=3000
F=3000
Now I need to just say 5 pc set and it should be automatically populated. And also if order have combination of individual and set items.
A customer's name is SZEE. Seek him through the SName textbox with Find, and Access can't find him. (Same in the table.) Seek him with a wildcard Sz* and there he is.
I've tried it on another machine - also with Access2k - and it's the same.
Is it an Access quirk? Is there an answer? (The client asks why. Be good to be able to say.) Cheers.
I am just about to start a new DB, but there are a few things I need to sort before i start.
I am working with a quotation system etc which will require the use of unique IDs...
eg 000123 then 000124 etc, this bit is not a problem.
The thing I would like to know how to do is when someone makes an order, I would like the quotation number to be changed slightly to add more detail.
For eg, If the quotation number that is allocated is 00123 and they then order a Conservatory, I would need to have this 00123 become 00123CNS, but this can be in a seperate field, Which I would need anyway.
The question is, How Would I go about this.
I have a table that describrives the product, TBL_PRODUCTS; ID, Product_Type, Product_ABBR
Product_Type = for e.g Conservatory
Product_ABBR = for e.g CNS
I would need the ref number and product abbr combined to create an order number.
[note] There will be a check box to say of ordered ot not, so I assume there will be an If statement somewhere?
I've made a button on my form which adds a booking ID into the listbox, but it doesn't seem to work. This is my code:
Private Sub Command18_Click()
Dim BoI As String
MsgBox "Booking successfully added!", vbInformation, "Booking"
If Month(Me.Date_1) = 1 Then
ListJ.AddItem Me.BoI
ElseIf Month(Me.Date_1) = 2 Then
ListF.AddItem Me.BoI
End If
End Sub
If someone could tell me the problem, I'd appreciate it. Thank you. :)
How can I increase the number of items on a Switchboard?
When I change the code, "conNumButtons = 8" to 20, an errors says only 8 items are allowed on a switchboard page.
When I select debug, the VB opens and the following line is highlighted yellow: "Me("Option" & intOption).Visible = False"
Do I need to change this line, or delete? to accommodate more items on a switchboard page, or am I stuck with only 8 items?
Thanks.
MsgBox "Booking successfully added!", vbInformation
'Depending on which month is booked, will determine which listbox is goes in on frmMain
If Month(Me.Date_1) = 1 Then
Forms!frmCurrentBookings!ListJ.AddItem = Me.BoI 'Add to ListJ on
frmCurrentBookings
ElseIf Month(Me.Date_1) = 2 Then
Forms!frmCurrentBookings!ListF.AddItem = Me.BoI 'Add to ListF on frmCurrentBookings
End If
End Sub
So basically... I have a date field in the form 'frmAddBooking'... if the month of the date is 1 (January), then the conntents of the date field is added to a listbox in a different form (frmCurrentBookings)... but this doesn't work...
If somebody could help me I'd appreciate it greatly.
I've been running into this problem in Access. I have records which have more than 255 fields. The easiest solution would have been to get a table with more than 255 fields, but I can't do this, so I've had to split up the tables. The next easiest solution would be if there is a way to link the tables--I have a data field "IntAccNum" identified as the primary key in each table--so that when a new row is formed in one, it is formed in the others. This wouldn't waste space, since any row in the first table would necessarily need a corresponding row in other tables. Is there a way to do this?
If not...
The problem I run into is when I populate a row in the demographic table and then try to fill a corresponding row in another table. I use a command button to for a macro to "OpenForm", and then try to "SetValue" of the appropriate field in the second table. This adds a new row in the second table. This does let me populate the correct row of the second table the first time I try for each row. However, after this initial population, when I switch back and forth between the first and second table, I get an error in access since obviously I can't keep adding a primary key with the same value in the second table.
Do I need to do some sort of query to see if that row exists in the second table already. Or is there some simple solution to what must be a very common situation that I am overlooking?
I've been on other forums with this problem but no one can solve my problem.
I've created a database with 3 tables that are linked:
- tbl_customer
- tbl_rates
- tbl_destination
They have the following fields:
tbl_customer
- cust_id
- customer_code
- first_name
- last_name
- company
tbl_rates
- rates_id
- cust_id
- rates_id
- currency
- pre_rate
- cur_rate
- fut_rate
- comment
- eff_from
tbl_destination
- dest_id
- destination
- destination_code
What I've done is created a form based on the tbl_customer table and used tbl_rates as a sub form. tbl_destination is used to populate a combo box that is situated in the sub form.
Each customer has their own rate sheet. Each rate sheet has different destinations and rates. Rates for the same destination are constantly changing. I need to use this spreadsheet to record the history of every change made to the rates of a particular destination. To do this I've just added the same destination with a new rate.
Now, what I want to do is to create a query that will only show the latest entry of a particular entry.
Eg. tbl_rate
Rate_id - Dest_id - currency - pre_rate - cur_rate - comment - eff_from
1 - 1 - £ - 0.01 - 0.03 - increase - 19 Sept 05
2 - 2 - £ - 0.12 - 0.14 - increase - 19 Sept 05
3 - 1 - £ - 0.03 - 0.02 - decrease - 23 Sept 05
I would want the query to show me the following from the above table:
Rate_id - Dest_id - currency - pre_rate - cur_rate - comment - eff_from
2 - 2 - £ - 0.12 - 0.14 - increase - 19 Sept 05
3 - 1 - £ - 0.03 - 0.02 - decrease - 23 Sept 05
Basically, the query should only show the latest entry which involves Dest_id '1' because there were two entries with the same id.
I've been given advice about this issue but none that actually work.
I would be grateful for any help on this matter.
So I've read a good 100 postings or so so far on the subject of how generating a unique identifier through any other means than an autonumber can be dangerous. But I can't resist the opportunity to simply ask if there is a way to make this possible, if only through a calculated field...
In my single user database, I have an employment table with an autonumber [EmploymentID] field as its primary key. The employment table exists in a one-to-many relationship with it's child, the income table where each form of income is recorded as it is recieved so that one form of employment (or employer) can produce many unique forms of income (like weekly paycheques).
I would like to be able to generate an identifier for the income table that is a combination of the parent [EmploymentID] field and an increasing number to produce something that looks like this:
1006789-001 -|
1006789-002 -|--> Same EmploymentID
1006789-003 -|
1006790-001 ----> New EmploymentID with a reset numeric
Any ideas?

Hello Everyone,
I've data already entered (access/tables) on two different computers, however for the clientid on one computer has a hypen (-) and on another - because of something they couldn't get the hypen to work - so they used the slash (/) my Q is: 1) can I search and convert these to one, 2) is it wise the have / or - in the id?
I am very new to db programing so please forgive for such a simple program.
Here is the deal. I have a db for about 500 students.
I would like the table [Students] to create a unique ID "number" for each student. I would like the number to be based on information from the same table. For example if the student's name is John Doe and his number is 555-1212 then I would like to the id to be JD1212. I plan on using more than name and phone number but this was just to show you, what i am trying to get done.
I can do this using a form and a calculated control, but I can't get the table and form to kiss and make up. I was also told you can't save data from a calculated control in a form to a table and it is gernerally not a good idea, so I was told.
Any help would be appreciated.
Sincerely,
Pastor Nick.
I have a beginner Question....How can I set an unique Index on a field in a table if all the four fields are using duplicate values?
View 3 Replies View RelatedI have thought about this for days now (and nights) and I have simplified my problem below. (I even bought a book)
I have three tables: 1, 2 and 3.
Table 1 = a, b and c
Table 2 = x, y and z
Table 3 combines table 1 and table 2; ax, ay, az, bx, by, bz, etc.
Table 1 and Table 2 are both One to Many with Table 3.
The Table 1 field and Table 2 field are a ‘unique’ index combination.
My Problem:
It would be very handy to produce a list of the ‘unique’ index combinations that are not in Table 3. That is, the ‘unique’ index combinations that aren’t used yet.
You could do this by trial and error, but is there a Query you can run that will give you a result that you could then Append?
An Unmatched Query on the Table 3 / Table 1 contents will point out a complete lack of either a, b or c as will the same Query on Table 2 for missing x, y or z.
A query with the two non-linked tables will give every combination, but is this the best way to do it? It works by default when you use it to append table 3, but is it the best way to do it?
Hi There,
I am setting up a basic Data Licence database. For each new record I enter I want a unique number to appear at the top of my form that can not be changed. I would like the number to be the date it is entered plus the auto number so, YYMMDD-(auto number) eg 071001-1. I'm sure it's something simple but I am only new to access.
Also while I'm here, on my form I have a Product field, how can I make it so I can enter in more then one product?
I would really appreciate any help!
Thank you,
Dane
Is there a way to format the random auto number to just be 4 digits long? Or does anyone know how I can programatically create an auto unique field? This number has to be stamped on a key so it can't be longer than 4 characters but it has to be unique. Any help would be greatly appreciated.

I have been discussing DB table design with a colleague and we have a difference of opinion with regards to primary key ID fields .
My argument is that they should not be actual data but separate, that is an unique record identifier typically an autonumber type. I'm sure I picked this up from reading Access manuals.
My colleague's argument is: if the data contains a unique field, e.g. a unique project number in a table of projects (no project should be listed twice) then use the project number as the primary key. Her second argument is the byte size of an autonumber is 8 bytes whereas you can use a smaller data type to hold the project number thus saving space.
My opinion is that her first reason is flawed as it assumes no change to how projects are identified and that her second argument is irrelevant in today's Gb and Tb systems.
Without trawling through my Access books and the internet for opinions, I would like to know what your opinions are on this subject. I would appreciate good reasons which ever side of the fence you are on. I'm quite willing to be proved wrong and change my ways.

I have a query which displays two fields: client ID and order type. I want to be able to display the client only once per order type. I tried to use GROUP BY order type but that gives me a missing expression message. I also thought of using UNIQUE as YES in qry properties but I'm not sure as to which row that property applies (all of them?). What is the best way to display a unique client in one row and order type in the other? So for example for order type "CASH" I wil then have a list of unique individualIDs.
thanks,

Hi,
I have been trying for the last couple of week or so to get a query working.
Basically the query is used to show Hours worked by Post Code. Everything works fine and the query returns 'Hours Worked By Postcode' and Number of Records that the data was created from. (See Report in Attached DB)
However I have now been asked also to show the number of unique Members who by PCode make up the records.
So the report would look like:
By Post Code (See Report)
Number Of Members - Number Of Records - TotalTime
I am having problems returning the number of Unique Members who make up the data, in the query you will see Test and Test1 where I have tried to implement a unique count with no success.
Any help would be appreciated.
Thanks

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,
