Return One Unique Instant Of A Field From A Query

Oct 16, 2007

Hi,

I've been given a flat-file database to 'improve'. One field is simply titled 'Room' and refers to a room number in a school. I want to create a MakeTable query that will run through all the records and make a table containing one instance of each room number (for normalizing). Hope that makes sense!

Any help much appreciated,

Steve

Queries :: Return Unique ID For Any Client Who Attended Any Event

May 2, 2013

I have a query to find only the unique clients that have attended an event during a time period

I can only get the event and client for each event

So I want a query that returns the clientID for any client that attended any event.

I have tried using the return unique values in the property sheet but that still gives me multiple clientIDs with each event they attended.

Unique Query Based On Single Field?

Apr 11, 2008

Hi Guys, I'm new here and fairly new to anything indepth with Access.

I'm using Access 2003 and have a table which has a number of customer records. The two relevant fields are the CustomerID which is a simple integer and OrderDate obviously this is a date field!

What I need (to link in with the other forms) is a query that will return one record for each CustomerID it should be the most recent OrderDate.

I've had a few attempts and done a couple of searches but can't seem to find exactly what I'm looking for. If someone could point me in the right direction I'm happy to play with sample code and read up on bits other people have done (I tend to learn better that way) rather than just being given some code!

Thanks for any help you could can provide.

Query To Return A Field To Determine Value For Report

Apr 14, 2008

I have a field on a report which I am struggling to produce the right query for.

I have a table - tblTillDept which consists of a 4 fields. The first is the PK, which is the number of a till department. The second - fourth fields are names of 3 different branches of the small garden centre I am writing the database for. The values in these fields are the names of the corresponding departments. Not every branch has exactly the same name for each field.

Prior to the report being is run, a small form, frmCentre pops up asking the user to select the Centre they are printing the labels for. They select the name of the branch from a combo box (cboCentre) bound to a field list of tblTillDept. When the report is formatted, the intention is that the value of this combo box selects the field from which the value for the department is taken. I can see that I need to set the control source of this property to some sort of query, but I can't quite work out how to do it.

I've uploaded the database, written in Access 2000, here (http://www.moppy.co.uk/plants.mdb) as it's too big to post as an attachment.

Query To Return Records Containing 2 Characters In A Field

Sep 5, 2013

I have a field in Access 2010 called Section Number which generally holds two characters. The characters can be numbers, letters, or a combination. Examples are:

01
X1
KA
40

Sometimes this field holds three characters, such as:

01a
02b

I want to write a query that returns only the Section Numbers that contain two characters. The instances where the field holds three characters are too numerous and changeable to use a parameter that says, for example: not "01a" and not "02b"

Is there a way to write a parameter that means "not Section Numbers of three characters" or "not Section Numbers of more than 2 characters"?

Unable To Return Query If A Field Is Left Blank

Dec 27, 2007

Hi all,

I am having a problem getting my query to work properly. I have read through this query section but it just got me more confused. I know some have used IIF function but it didn't work for me.

here's my code:

SELECT tblEmployee.UserName, tblODF.ODFNumber, tblQueue.Queue, tblStatus.Status, tblODF.ODFScanDate
FROM tblStatus INNER JOIN (tblQueue INNER JOIN (tblEmployee INNER JOIN tblODF ON tblEmployee.EmployeeID = tblODF.EmployeeID) ON tblQueue.QueueID = tblODF.QueueID) ON tblStatus.StatusID = tblODF.StatusID
ORDER BY tblEmployee.UserName, tblStatus.Status, tblODF.ODFScanDate;


I want everything to show even if one of the fields is blank.

Thank you

Queries :: DLookup To Return Value Of Field In Query Expression

Oct 30, 2013

I have a field created in a query expression

BirthMon: Format([DOB],"mmmm")

I would like to create another field in the query using DLookup to return the value of the BrithMon.

BrithMonthID=DLookUp("MonID","tblListMons","BirthM on = Mon")

This works good if used with an unbound text box on a form, but when entered into a query expressions, an error is returned: cannot find the name 'BirthMon'

Can I used DLookUp in a Query expression to refer to another Query created field?

Modules & VBA :: Return Rows In Query From Variant Array Return From UDF

Sep 16, 2014

I have a simple UDF that takes a string and returns a variant, which is an array of strings Example Input "Brick Wall" Return value would be a variant array with first element "Brick" and and second element "Wall" Now I have a table with a field of strings, and I want to make a query that returns all the results from the function, one per line.

So if my input table looks like this

[strField]
"kick the ball"
"return the pass"

my query result should looks like this

[Orig] [new]
"kick the ball" "kick"
"kick the ball" "the"
"kick the ball" "ball"
"return the pass" "return"
"return the pass" "the"
"return the pass" "pass"

Last time I had to do something like this I used VBA exclusively, with ADO objects, but I thought a query based solution would be easier.

With my current data the largest return array size my function returns is 27 elements but I wouldn't want to rely on that number being fixed.

Modules & VBA :: Return A Value From A Separate Query / Have To Show Up In A Field On Main Form

Jun 28, 2013

I want to return a value from a separate query and have that show up in a field on my main form. The field name from the query is "Six Month Date" and the query name is "DT6Monthqry". I want to return the value displayed in the"Six Month Date" from the query, matching the CustomerID in the query result to the CustomerID that is being displayed on the main form. The CustomerID is a text field.This is the code I placed in the Control Source property for the field I want to be displayed on the main form:

=DLookUp("[Six Month Date]","DT6Monthqry","CustomerID=" & [CustomerID])

The result of this displays a flashing "Error" in the field, even when I go to a Customer that I know has a result in the "DT6Monthqry".

Queries :: Date Range Query - Return Lines Where Field Is Blank In Table

Aug 15, 2013

I have a single table with customer information, one of the fields is a date field "LastContacted".

I'm creating a search form with 2 date fields (txtDate1 & txtDate2) to search a date range of the LastContacted field, and I need to write this into the query that the search form uses.

I have written this using Nz so that it can still return results if the search boxes are left blank:

Between Nz([Forms]![frm_AdvancedSearch]![txtDate1],#01/01/1989#) And Nz([Forms]![frm_AdvancedSearch]![txtDate2],#01/01/2999#)

This seems to work and it returns lines from the table where there is a date entered. However some of the fields in the table have no entry in the LastContacted field. How to code this query so that it also returns lines where the LastContacted field is blank in the table?

I have tried:

like "*" & (Between Nz([Forms]![frm_AdvancedSearch]![txtDate1],#01/01/1989#) And Nz([Forms]![frm_AdvancedSearch]![txtDate2],#01/01/2999#)) & "*"

but this returns errors when I try to run it.

I'm using Access 2010.

Unique Field

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.

Unique ID Field

Apr 18, 2008

Hi all
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.
Cheers
Imperator

More Than One Unique Field - Simple One.

Oct 18, 2005

Wotcha, folks.

I'm in a right pickle at work at the moment.

For the life of me I can't make an Access table have more than 1 unique field.

For example, I want a company's name and postcode to be treated as unique ONLY when they appear together.

So I can have many companies with the same name and different postcodes, but no doubles of the same company name and same postcode.

Does this make sense? How do I trigger a unique property when two certain fields match a previous entry.

I've searched on the net and in these forums, but i can't find help. Maybe it's the way I'm wording it.

So, sorry if this is incredibly straight forward, and I'm being a noob, but this is rather urgent.

Many thanks.

Jake.

Multiple Field Unique Information Db?

Aug 14, 2006

Hi, I'm crating this db:

Two tables, in one there are Items and services, in the other purchases.

1st table: ID - autonumber primary key
Product Name - Text
Quantity - Number
Barcode - Text

2ndt table: ID - autonumber primary key
Product Name - Text
Quantity - Number
Barcode - Text
Client - Text
Puchase Date - Date

How can I enter data to my 2nd table using unique fields (barcode, Product name actually ID in 1st table?) Problem Is Access alows only 1 unique key field in table and that is undertandable. Is there any way out in my situation.

barcode will be entered using barcode scanner it can be only text field but information like product name must fill in automatically, Product name must be drop down box if one wan't to select it manually then barcode should fill in automatically.

Please Attach your DB if you have time to look into this issue.

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.

Show Records With Unique Field

Jun 8, 2006

Hi,
I have two tables:
tblOutTransmittals and tblTransmittedDocs. A document is sent with a transmittal document which the recipient signs to confirm that they received it. I've created a query that will show all the drawings/documents and the information about the associated transmittals.

What I want to do is show display records with a unique CCNum and preferably the one with the most recent TransmittalDate.

I've attached a screenshot and here is the sql:
SELECT tblOutTransmittals.CCNum, tblTransmittedDocs.DrawingNum, tblTransmittedDocs.RevisionNum,tblOutTransmittals. *
FROM tblOutTransmittals INNER JOIN tblTransmittedDocs ON tblOutTransmittals.DocID = tblTransmittedDocs.outTransmittalID
WHERE tblTransmittedDocs.DrawingNum="32-35554"

I've tried it using the DISTINCT keyword but that would only work if I'm returning one field. I tried Group By as well but couldn't get that to work.

Thank you,
RCurtin

Total Of Unique Items In A Field

Jan 18, 2005

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!
Stu.

Tables :: How To Create A (unique) Field

Nov 12, 2012

I have a table as followed;

EmployeeID: PK
FirstName
MInitial
LastName
Company:FK
Department:FK

What I want to do is create a new field that automatically populates based on what is entered into the above fields.

Essentially creating a single field with unique data generated by multiple fields.

For Example if I entered the following informaiton:
EmployeeID: 1 (AutoNumber)
FirstName: John
MInitial: P
LastName: Doe
Company: FederalGov
Department:Test

The new field can be generated as followed: JohnPDoeFederalgovTest

What i plan on doing with this is making this "generated" field an index so no new duplicated records can be added.
