Create Primary Key From Values Entered In The Field
Nov 28, 2014
I have two Tables, Table A and Table B...Table A and B have a one to many relationship with A (one) and B (many).I have a Master form that displays information for Table A. Also, I have a subform within this Master that displays information for Table B.
As I scroll through the records of A, you can see the 1-many relationship elucidated in the subform with many being displayed for Table B.I run into a dilemma, though, when I try to ADD a new record to Table A (and in turn Table B).When I add a new record, there is no Primary Key left to be displayed since this primary key is generated from a query.Hence, when I move to a new record, I can not save the record because there is no primary key. Since there is no primary key, there is nothing that i can input into the subform either. I want to create the primary key from values entered in the field. However, i CAN NOT create a relationship with an expression for field values.

Is there a way to create a relationship so when a new record is entered into the main table it automatically creates a new row/record in the related table with just the foreign key entered?

This is a real mind bender.
I am running a2k. I am merging two databases. table1 is in the backend database. table2 is linked to the second database.
I run an append query to add table2 entries to table1. The append fails for 96 recs saying key violation. Turns out I can rerun the append if I drop the zip code field.
I then try to manually change the zip code and receive the duplicate values in index, primary key, or relationship.
I ran a compact & repair the databases, still no go. I can't edit the value of the zip code. I import the table to a new database. Still can't change the zip code. I drop MANY of the indexes. Even the index on the zip code field. Run compact&repair. still getting the index message. I even re-imported to a new db again. Still same error message.
I may start again by importing JUST these two tables to a new blank db and see if I get the same issues. I'll keep you posted...but maybe there is someone out there who has seen this error before.
fyi-if I enter a new record, the autonumber field correctly increments to the next available autonumber field. (I say this because of another thread on this matter w/ autonumber fields and bug in A2003)

In table 1 fields Factor, Aggregations, Stat, and Days Back are fields that make up a multi-field primary key [URL].
I want to create a relationship between that multi-field primary key and another table, call it table 2, and make it a one-to-one relationship.
How do I do this in MS Access 2013?

Access 2010..One organization that we work with provides us with a block of numbers for each of the two types of contract products we order from them; we do order non-contract stuff from them also.The block of numbers are the same (i.e. 20000 to 30000 this year) for each of the two products. This means that each product can have the number 20000, for example. We call this the Tracking Number. If it is one of these products, we need to select the Contract Number.
For all other one off orders we have with them, we assign our own Tracking Number starting with 00001. This Tracking Number cannot duplicate unless it is one of the aforementioned two products.Both the Tracking Number and Contract Number are in the same table. The user selects the Contract Number from a form (connected to the Contract Number table that has all the details on the contract) and the Contract Number is populated in the same table that has the Tracking Number.Each order must have a Tracking Number (no null)..Not all orders need a Contract Number (null okay).The Tracking Number and Contract Number combination cannot duplicate.I tried setting the primary keys to more than one field in the table, but they cannot have null values.
If not... I have been working on Plan B.... an AfterUpdate on the form (either the form or a field... don't know yet) that looks at a query that only has results if there are duplicate values.

A have a query that selects a multivalue field. The query forms the record source for a subform. The text values in the multivalue field are displayed in the query, but when I save this and view the data in the subform datasheet view the values revert to the primary key values. They are 1,2,3,4 instead of the text values

How can I use different fields values to compose a paragraph? I want to make a shipment notification letter using different fields. For Example,
Hi [ShipToName],
Your order of book [BookName] has been shipped via [Shipping_Service]. The tracking No. is [TrackingNumber].
Your order has been shipped to following address,
[ShipToName]
[Street1]
[Street2]
[City], [State] [ZIP],
[Country]
Then I also want to email it using outlook 2010 but that might be a different thread.

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

I really need some help with this! I have a table with a field called [days.out]. It contains values from 1 to about 350, non sequencial with duplicates. I would like to run a query that would create a new field called [days.grouped]. This field would contain the word "1-15" if the value was between 1 and 15 in field [days.out] and "15-30" if value was between 15 and 30 in field [days.out], etc....
Hope someone can help me!!

create an expression in the Validation section to prevent duplicate entries in a field. Please view Powerpoint file on slide 1 on attachment for More detail instructions. Instructions are in simple Text and images which makes it easy to understand. I am using Access 2003.

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.

I have a form that collects a survey where the user selects between 1 to 9. I was wondering if the user selects a certain range, for example between 1 to 4 a yes/no dialog appears. If the user selects a range from 5 to 9 , they get no dialog box.

I have a rather interesting situation involving creating a primary key. Basically I have two tables.
Table 1
Date, Customer, Part Number, Work Order, Qty tested, qty failed, tech name
Table 2
Defect, reference, quantity(defect), defect cause, part number, work order
The ideal relationship I want to create is that for every Table 1 there are multiple table 2. Regular one to many relationship. The problem is that in the first table it is possible and probable that there will be duplicate records because of the process. The test parts by individual carts, but often they're exactly the same parts with same work orders and same everything else. How should I go about doing this. I don't want to just create an autonumber for each record if possible. Any suggestions?

Hi all,
Please bear with me if I'm asking a dumb question. I've been tasked to create a database from scratch and I've not had much experience working with Access.
**My Question**
Using a form is it possible to have the form automatically enter a "value" in one field based on the information inputed by someone in a different field.
ie. When some one puts in a value between 0 and 20 in one field it automatically enters a 1 in the other, and when some one puts in a value between 21 and 30 you get a 2 and so on down the line.
Thanks for the help.
Cheers

I have two tables tblPatients (pkUMRN) and tblAdmissions (pkAdmissionID, fkUMRNAdmission). pkUMRN is not auto-number, but is an 8-digit alphanumeric code unique to each tblPatients record. I have set up a one-to-many relationship between tblPatients_pkUMRN and tblAdmissions_fkUMRNAdmissions (each patient can have multiple admissions).
Is it possible to allow the entry of a new tblAdmissions_fkUMRNAdmissions to create a new tblPatients_pkUMRN? IE can you create a new primary key from a new foreign key?
Along a similar line, if the primary key already exists, how would you autofill a form with data from tblPatients when the tblAdmissions_fkUMRNAdmissions is entered in to the table?

I'm attempting to build a simple database for a martial arts tournament registration. The weight division (Fin, Fly, Heavy, etc.) depends on the age, the sex and the weight. I've tried this several different ways, most recently by using one table called "competitors" with all the entrant's information, and several other tables based on the age class/sex (i.e. I have a table called Age 8-9 Male with the weights and divisions in it, and other tables for the other ages/sex).
So, basically, what I'd like to have happen is a report that will lookup in the correct table the division, based on the weight entered. In other words, for a record where the age is 8-9 and the sex is Male, the report compares the weight to the values in the 8-9 Male table, or if the record is a 12-13 Female, it looks in the 12-13 Female table for the weight, and places the correct division in the Division field of the report.
Probably going about this wrong.....but any help would be appreciated.

I have a textbox & button that when entered & pushed - run a query for the top values randomly depending on the value entered into the textbox.
My code is...
strSQL = "SELECT TOP " & Me.Text140.Value & " [CAN - NAME].Name, [CAN - CPT/VOUCHER].Voucher_Number, " & _
"[CAN - CPT/VOUCHER].Procedure_Code, [CAN - CPT/VOUCHER].Service_Date_From, [CAN - CPT/VOUCHER].Patient_ID, [CAN - CPT/VOUCHER].service_id, Rnd([service_id]) AS RandomNum " & _
"FROM [CAN - CPT/VOUCHER], [CAN - NAME] WHERE [CAN - CPT/VOUCHER].Service_Date_From Between " & Me.StartDate.Value & " And " & Me.EndDate.Value & " ORDER BY Rnd([service_id]) DESC "
It runs like it should but doesn't populate any records...that is until I go into the design view, deselect one of the fields and then reselect the same one - only then does it populate.
Do I need to open the query first and then update/append instead?

I have an append query that currently looks like this URL...This query automatically adds the machine parameters for a product code and lot number into the running condition log. This is so the user does not have to manually go in and tediously select each machine parameter.
The running condition log also has a date field to specify what day and record number the machine parameter's value was recorded on. When I run the query the appended rows look like this. The product and lot are defined by user parameter and there are actually about 36 machine parameters
Code:
Productstockcode LotNo Day Record Parameter ActualCond
PE-500 130816m71 StockTemp
PE-500 130816m71 Zone 1
PE-500 130816m71 Zone 2
My question is: how do I modify the query to automatically add the date and record number in one shot? It needs to be user defined at the time of the query because this data is not stored anywhere else in the database. For each 36 machine parameters the day and record would be the same.

Hi - it's been a while since I did much access and am trying to help someone out and have got into a pickle! A quick job has turned out to be a lot more complicated! Plus I'm having to use *spit* Acc 2k.
When I go into frmHighCostDrug (from the "add new drug episode" button on the frmPatient) I often get the message "The changes you requested were not successful because they would create duplicate values in the index, primary key, relationship etc etc."
Now, I didn't think I'd forgotten that much. I've got primary keys, values in the table set to Null, relationships set and ref integrity set and cannot for the life of me see why this is happening.
I know though, that one of you will say "oh it's that" and point it out and I'm going to feel completely stupid, but at the moment, I don't mind! I really can't figure it out.
I've attached db - it's in Acc2k and I tried to do a copy Acc'97 for those who don't have it but it caused no end of problems. Came up with messages that this form contains data that Access doesn't support!!!! ??? :confused: If I can sort it I will.
If anyone's got any ideas, I'd be v grateful!
Tnx
Ally

I need to create a query that strings data horizontally that corresponds to the primary key.
Example of what I am looking for
Fields:
Part_No,
Mfg_No,
Mfg_Name
Query Columns: Part_No, Mfg_Info (Mfg_No: Mfg_Name)
Also if the part_no (primary key) has multiple values I need the data to string horizontally like this:
Part_No, Mfg_Info (Mfg_No1: Mfg_Name1),
Mfg_Info (Mfg_No2: Mfg_Name2).......

I have a very basic three table structure.
Clients
ClientID (PK)
ClientName
Boats
BoatReg (pk)
ClientID (FK)
Description
Quotes
QuoteID (Pk)
ClientID (fk)
BoatReg (fk)
What I would like to do is for the BoatReg field in the Quotes Table to only display the boats that have been registered to the Client that has been selected, currently it displays all the BoatRegs.
