Tables :: Merging 2 Fields Together To Create Additional Field - Unique References
Jul 23, 2015
Is there a way of merging 2 fields together to create an additional field
my database consists of 4 main tables (in order of relationships)
*HeadOfficeDetails
*SiteDetails
*ContainersOnSite *Contracts2015-2016
For example;
Account Reference: TEST
Site Number: 001
and the field i would like to have;
Site Reference: TEST/001
I would also like that when i add a new site to that account i will have TEST/002....

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.

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.

I have a table - (Table A) that has 2 fields X and Y. I would like to write a query or script to make two new tables based on the unique values found in field X. In other words, all data where field X = 1 would be written to a new table called "1" and all data wehre field X =2 would be written to a new table called "2".I would like this done automatically.
Table A
Field X Field Y
1 a
1 b
1 c
1 d
2 a
2 b
2 c

The code pasted below creates a union query for a set of tables (J000171, J000174, J000178 etc) and stores the results of the query in a table called temp.
The first piece of code queries the ‘status’ field of a table rjobs for those records with a ‘status’ field of “Live”. Another field within this rjobs table, ‘JobID’, happens to be the name of a table where additional information relating to that job record is held eg. J000178 All of the tables selected in the query on rjobs are then included in the union query.
The second piece of code stores this information in a table called temp
I would like to be able to do 2 things with this;
1.add an additional field to the union query which holds the JobID field value from rjobs (or alternatively the table name from which the data originates eg J000178 etc as that is the same as the JobID file din rjobs)
2.create an option to clear the info in the temp table. Currently additional info is appended, so whenever the query is refreshed new data is simply added to old data. I would like to be able to clear that data where possible.
The union query is run from the on click of a command button on a simple form. Perhaps an additional button could be used to clear the records from the table temp.
Any ideas greatly appreciated.
Here is the existing code …
Option Compare Database
Option Explicit
Private Sub Command0_Click()
Dim db As Database
Dim rsRjobs As Recordset
Dim rsRapps As Recordset
Dim LengthofUnionSQL As Long
Dim sql As String
Dim UnionSQL As String
Set db = CurrentDb
Set rsRjobs = db.OpenRecordset("Select * from rjobs where Status = 'Live'", dbOpenSnapshot)
Do While Not rsRjobs.EOF
UnionSQL = UnionSQL & "Select ObjectID, SearchNo, DateSearched, Consultant, from " & rsRjobs!jobID & " Union "
rsRjobs.MoveNext
Loop
'following two lines are to remove the trailing word Union from the string unionsql
LengthofUnionSQL = Len(UnionSQL)
UnionSQL = Mid(UnionSQL, 1, LengthofUnionSQL - 7)
' Now variable Unionsql will hold the value something like
' Select ObjectID, SearchNo, DateSearched, Consultant from J000145
' Union Select ObjectID, SearchNo, DateSearched, Consultant from J000146
' Union Select ObjectID, SearchNo, DateSearched, Consultant from J000147
MsgBox UnionSQL
Set db = CurrentDb
Dim rsUnionquery As Recordset
Dim rstemp As Recordset
Set rstemp = db.OpenRecordset("temp", dbOpenDynaset, dbSeeChanges)
Set rsUnionquery = db.OpenRecordset(UnionSQL)
Do While Not rsUnionquery.EOF
rstemp.AddNew
rstemp!ObjectID = rsUnionquery!ObjectID
rstemp!SearchNo = rsUnionquery!SearchNo
rstemp!DateSearched = rsUnionquery!DateSearched
rstemp!Consultant = rsUnionquery!Consultant
rstemp!jobID = rsUnionquery!jobID
rstemp.Update
rsUnionquery.MoveNext
Loop
End Sub

I'm creating a database for a travel agency. There are 2 tables, one for customers and one for their bookings. I have established a relationship between the tables so the AutoNumber for customer ID links to a field on the add booking table.
In practice though, it would be easier to enter the customer NAME into the booking table and have it retrieve their ID that way to link them. This seems like I am missing something simple but can't fathom a way to do it.
The other factor is obviously more than one customer will have the same name so I may need to link first name as well to differentiate?

I have a database that will take lots of data entered by an employee and calculate some additional data and generate quotations. Within each quote there is a possibility for 15 different metals (5 Precious Metals, and 10 Base Metals). There is also 5 fields that need to be filled out about each Metal (What the metal is, the market being used, weight, whether it is included in a different price, and the price). I currently have 75 fields to address each Metal and their 5 fields respectively. Is there a better way to Normalize this data, and accomplish what I need accomplished? I want at the form level the employee to tell the database whether they want to add a Precious Metal, or Base Metal, or Move on to other data entry.
Here is a Screenshot of the design view of one of my tables with too many fields : table screenshot1.PNG

The main table for the database I am working on contains the following fields:
ID
Mfr Control Number
Initial or Follow-Up
Follow-up Number
Suspect
Date of Initial Email
Date Received
Date Submitted
Date of Report
Serious
Brief Description
Causality
Notes
With some additional qualifications I wanted to find records that had an intial report but no follow-up. Which translates too I want records that are unique in the Mfr Control Number field (no duplicates).
I am trying to build a query and keep getting hung up on the unique aspect of fields. I started by trying to query only "Mfr Control Number" fields that are unique (no duplicates). As best I can figure for some reason I can not add any additional fields to that query. My current query is set up in the query build table such that I have added "Mfr Control Number" in two columns. The first column in Total I have "Group By". In the next column I have set Total to "count" with a criteria of 1. If I try to add any other fields from my table than I seem to lose those unique results. But I need to further filter to get the exact information I need.
I want criteria on the "Initial or Follow-up" field to only bring "initial"
I want criteria on the "Serious" field to only bring "serious"
I want criteria on the "Date of This Report" field of "<Date()-"15""
Is there some way to take the results of that initial query to then build a another query based just on those records? I could then apply the further criteria and run my report. Or is there a way to do this in one step?
I've tried to make clear my intention but know it can be difficult to get this kind of stuff down in writing in a clear fashion. I have to be careful to keep information confidential also so some of the details are vague.

The interface being used is a main form with various tabs and a subform on each of these tabs.
There is one field ('max power density') in my database that is calculated using 'Max Rated Power' and 'Cylinder Capacity' however these are in different tables and subforms. The 'max power density' and 'max rated power' are in table and subform 1 but 'cylinder capacity' is in table and subform 2. Is it possible to keep them in separate tables/subforms and still calculate the field?

Have 2 tables:
...TableA: 1 indexed field "Name" and many data fields in ~ 1000 records
...TableB: 1 indexed field "Name" and 2 data fields (DataB1 and DataB2) in about
~ 50 records
Tables currently have NO relationship set.
Want to add TableB data fields to TableA if Name are identical.
DataB1 and DataB2 fields are Not currently in TableA but could be added very easily.
Update (or whatever) will be done weekly where all previous data for DataB1 and DataB2 will be cleared from TableA before job is run.

I have a table which has each claim as a single record. A client wishes us to provide the data in a format that lists the each procedure on its own line. I have attached a highlevel example of what the data currently looks like and what the query results should look like.So I need to create a query that would repeat the Claim Number and place all the Procedure fields into one field.

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 want Access to automatically generate a reference number for a record based on the values in on two other fields for a given record using a form.
The first field is called Operation Number.
The second is Bag Number.
The reference number needs to be in this format: 19C.3.1
Where 19C is the Operation Number, 3 is the bag number, and 1 is automatically generated. Additionally I need the last number --the automatically generated one--to go back to 1 if with each new bag number.
This is kind of like library catalog numbers. Not sure how to do this.

Currently am trying to get together two separate Access Databases into one, which is the way it was always supposed to be.
Basically, this person accidentally created a duplicate of the database in question, and has been updating both independently at different times, meaning that whilst a lot of the database information is duplicate, there are some instances where each separate database copy has unique information on both existing contacts, and new unique contacts.
The database itself is about schools, and has tables concerning information such as calls made, contact details, school details, etc etc. Obviously all of this needs putting back together into one set of tables in one file.
I've been messing around with append and import functions, but am having issues with duplicate ID fields with append queries, and a general lack of direction on the best way to go about fixing this problem, if its even possible.
Here's an example of what i've been trying to do:
INSERT INTO Contacts ( ContactID, ContactTitle, Name, Surname, JobTitle, TelephoneSTD, Telephone, FaxSTD, Fax, Locale, SubjectKeyword, SchoolID, Reply received] )
SELECT [1Contacts].*, [1Contacts].ContactID, [1Contacts].ContactTitle, [1Contacts].Name, [1Contacts].Surname, [1Contacts].JobTitle, [1Contacts].TelephoneSTD, [1Contacts].Telephone, [1Contacts].FaxSTD, [1Contacts].Fax, [1Contacts].Locale, [1Contacts].SubjectKeyword, [1Contacts].SchoolID, [1Contacts].[Reply received]
FROM 1Contacts;

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.

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 have downloaded a contact template from the internet ready to go. There are few things I need to get rid off and make changes to.
One of the most improtant thing is making one of the field unique. For some reason, i can get to the design view. I open navigation panel and right click on the table, there is no such thing call design view on the menu.

I have 4 fields in a table that when combined must be unique.I know you can setup multiple fields as a combined key, but I don't really need these to be the key (I will auto number a unique key). I just need to make sure the same combination of codes is not entered twice.Do I set this up as multiple key fields anyway?

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];

To prevent duplicate records, I use multiple fields indexes, which worked fine until now. I learned that each "empty" fields are consider unique by Access, so not the best in an index to prevent duplicate records. I managed to have it worked using the default value property to give each "empty" records the same value.
Now my problem is that I have a date field which is optional, but I need to use it as a unique identifier in an index. I could again use a default value, but since it has to be a date, I find it confusing. I would rather have a default value of "No date specified" or "-" or even better, "". Unfortunately none of those works with date fields.

I am trying to return the MIN in a numeric field (single result) from my database and I have no issues doing this BUT the problem is that I also need to display additional fields in order to make the result useful. The additional field can't be grouped by b/c that changes the result of the MIN function.

[AllItems] is a listing of account activity where the [AccountNumber] repeats. I have every field set as the "Primary Key" on [AllItems] as that is the only way to avoid importing duplicate data. I am getting the error: "no unique index found for the referenced field of the primary table"

In the code below I am creating a record with the INSET INTO statement and then Updating with additional info in various fields. it is not working the way I thought it would, so I am trying to create the record in it's entirety.
Code:

DoCmd.RunSQL SQL
[Code] ...
I am running to syntax problems when I try to USE the INSERT INTO to create the record with all the info in one statement.
Code:
SQLM1_1_ELA = "INSERT INTO Grades ( GUSD_Student_ID, Subject, Type, Score, Nam ) " & _
"SELECT (" & Me.GUSD_Student_ID & ")"" AS GUSD_Student_ID, ""BM2(ELA)"" AS Subject, " & _
