Hi, I have current yards table with Trailer number as the primary key and which cannot have duplicates. When this trailer leaves the yard we send this record to History table. Now if a trailer comes again and leaves History table is not accepting as it is duplicating. So can anyone help in designing table so that it accepts duplicate trailer numbers only in the history table.
Thank You,
Naveen
I have generated a combobox search for my form and I am able to select names that are different and the information is generated on the form. However, when I have two names that have the same last name my selection will default to the primary key instead of the name I selected in the combobox. Here is the code I am using:
Here is my RowSource: SELECT [Client Info].CltLname, [Client Info].CltFname, [Client Info].DOB, [Client Info].[Last 4 SSN] FROM [Client Info] ORDER BY [Client Info].CltLname, [Client Info].CltFname;
I have run a query to sort by CltLname and then by CltFname
Private Sub cboClientSearch_AfterUpdate()
'Moves to Customer Name text box and
'finds the record of whatever name is selected in the combo box
DoCmd.ShowAllRecords
Me!CltLname.SetFocus
DoCmd.FindRecord Me!cboClientSearch
'Set value of combo box equal to an empty string
Me!cboClientSearch.Value = ""
End Sub
how to get the combobox to display what I have selected instead of defaulting to the earliest primary key associated with the same last name?
I am designing a nomination form (web database so no vba macros can be used).
The form has 3 combo boxes: cboStaffName, cboLevel, cboNominee.
The form is bound to the tblSubmit table where the submissions are populated.
I used a select statement:SELECT Staff_List.Staff_Name FROM Staff_List; to populate the combo box for the Staff Name selection.
This is the select statement to populate the job level combobox:
SELECT Staff_List.Level, Staff_List.Staff_Name FROM Staff_List WHERE (((Staff_List.Staff_Name)=[forms]![frmtest]![cboStaffName]));
The select statement to populate the combobox for the nominee combobox:
SELECT Staff_List.Staff_Name FROM Staff_List WHERE (((Staff_List.Level)=[forms]![frmtest]![cboLevel]));
The problem is that the staff_name in the first combobox is still found in the nominee combobox which should not be because a staff cannot nominate self. There is a field in the Staff_List called YesNo that should be activated for each staff that is selected so that the select statement on the nominee combobox can be updated accordingly to remove items with the field "Active"
How to get the checkbox selected for each corresponding staff.
Sample of the database has been attached.
Porbably a stupid queston for most of you, but I am new to the game. Trying to get the selection of one combo box to filter the selections of a second combo box. Have one table called Sections with the colums SectionID and SectionName, a Second Table called SubSection with Colums SubSectionID, SubSectionName, and SectionID. Third Table called Points which has a column for Section, and SubSection, need to have the section combobox selection filter the SubSection combobox selections. Any help would be appreciated!
View 1 Replies View RelatedI have created a very simple Access database with a CompaniesTbl, ContactsTbl and CallsTbl. The database is used to record telesales contact with customers. The tables are set up like this:
The CompaniesTbl has an AutoNumber Primary Key field called CompanyID.
The ContactsTbl has an AutoNumber Primary Key field called ContactID and a foreign key called CompanyID.
The CallsTbl has an AutoNumber Primary Key field called CallID and foreign key called ContactID.
The relationships are set up in the relationships window and referential integrity imposed.
Twice now, while editing a contact record, an error has occured. Task Manager has had to be used to get out of it. The error is either a 'run-time error with a message that does not mean anything' or it says 'unrecognized database format' (!?).
If you open the database again the ContactID field in the Contacts Table is no longer a Primary Key field. If you look in the relationships window - the relationship between the Companies and Contacts tables no longer exists.
Any ideas much appreciated.
Hi,
May I know how do I go about getting the last value of the primary key that I get inserted? I need this PK to link the parent and child tables together.
Thanks for any valuable help!
Hello
I have a problem with a primary key. A table called relaties has a column relatienumber with date type: number, which is also the primary key. When a button is pressed, a function searches info from the table relaties.
The problem is the following: I figured out that when i remove the primary key constraint from the column relatienumber and save the table. the function doesn't work anymore, also when i remake the primary key for this column. How is this possible, because i changed nothing futher.
This is important because i want to change to access db to mssql db and in mssql the function also doesn't work.
It has something to do with this primary key constraint, i think :)
Who has the info???
Is it important that primary key would be a number for performance purposes?
How do I set 2 different fields as one primary key?
How do I set 2 different fields as two separate primary keys?
when defining tables, i normally set an autonumber as a primary key. However, i am working on a particular table, and i would like that no record will have identical values, in three particular fields
aaa bbb 123
aaa ccc 234
ddd fff 555
aaa bbb 123 <- i want to prevent this since a record with those three values already exists
Shall i set these three fields together as a primary key, or can i leave the autonumber as primary key and prevent such duplication in any manner ?
Thank You
Can a PK be a calculated field?
I want to be able create a PK that consists of three strings being added together. The first two would be collected from cascading combo boxes. The third field is a simple text field.
I would then run DLookup to make sure the final string is unique.
I have reasons for not using an autonumber field (there are compatibility issues with existing tables from a much older dbase database).
I have a database that I got up and running but one problem. I have as the primary key a social security number, but I can't seem to be able to add additional information to the same person. All I can seem to do is just replace or edit the one record. Is there a way that I can have more then one order for an individual instead of taking the primary key off of social security numbers?
Do I need a seperate form to enter information because I am currently workin with one form where I can enter and edit the information but no duplicates so lets say if my social was 099-999-9999 I can't add an additional order it seem unl.ess I make a whole new record and make a dummy number...
I have a tblState, every state can have multiple Counties, and every County can have multiple Municipalities
This should be a One to Many to Many, right????
However, several states might have the same County name
In order to resolve this, should I add 2 primary Keys in the tblCounty????
If so, I already tried and couldn’t configure it.
I have attached a sample DB
You can open the relationship view for a better explanation
I appreciate any kind of support
Thank you

I was wondering if anyone would be able to help me? I have two tables which can be linked together as they both contain a field called Company Name. However, in one of the tables I want Company Name to become my primary key but this field contains duplicates. How can Isolve this so that I can still link my two tables together?
View 2 Replies View RelatedHi all,
Ive written a program in .net and am currently using an access db as the backend.
In the db I had 200 test records which i deleted to get the db ready for deployment. When i add a new record now the primary key on my "booking" table carries on from the old test number so 201.
Can I resest this so it starts back at #1 as once the db gets updated, the program i wrote then takes the data and updates the accounting system and uses the primary key as the invoice number and so I would like to start at 1.
Thanks in advance

How would I go about changing the primary key to a different field in a table? :o Thanks for any help!
View 2 Replies View Relatedhey guys. i have a field by the name of ISSUE. i am using this afterupdate event procedure
which is as follow:
Private Sub ISSUE_AfterUpdate()
If Not IsNull(ISSUE) Then
ISSUE = Format(ISSUE, "000000")
End If
End Sub
if a user enter like (23) in my ISSUE field my procedure will run and it will replace
the number by (000023) to make it a six digit. i wanted to create a primary key so then a user cannot enter the same number again
or cannot duplicate a record but i cannot because primary key cannot take a null value. Can you all tell me anything to add in my procedure so that once the number is entered like (23)
another user cannot enter (23) again in the record.
Thanks

In the above the primary key would be the [Name] + [Date] but primary key only allows one field for key.
