Define Cascade From SQL

Oct 12, 2004

Hi, all... :)
I need to create cascade relationship on fly.
I've succeeded to create the relationship by:
ALTER TABLE tName ADD CONSTRAINT fk_id FOREIGN KEY(ID) REFERENCES tPrimary(ID)
and even succeeded to check the referential integrity by:
ALTER TABLE tName ADD CONSTRAINT fk_id FOREIGN KEY(ID) REFERENCES tPrimary(ID) CASCADE

The real problem comes when i am trying to enforce the cascades. I do not find any expression doing it.

the standarts of sql: on update cascade
or
of sql server: on update cascade go
just don't work in access :(

Thankful ahead

Cascade Deletes

Jun 13, 2007

I want to use Cascade Delete on a main table that has relationships with a few tables. The type of these relationships are weak and the delete will work perfectly I think. But, I am concerned about how I can only delete the FK from one of the tables because it contains a non-prime FK.

For example: Customer buys House. So Customer PK is in House as FK.
If I delete customer, I don't want house deleted. Is there anyway that is native to access in how I can only delete the FK from tblHouse without deleting the house record.

Cascade Combo - 3 Tiers?

Oct 14, 2005

Hello,

I followed the Microsoft guide detailing how to set up two cascading combo boxes. I would like to add a third box to the cascade. I have tried making some assumptions based on the code in the example but I can't get it to work.

I have three queries set up; qryBusiness, qryBusinessUnit and qryLocation.

I am using one form; frmToolInfo.

I have three combo set up; cboBusiness, cboBusinessUnit and cboLocation.


I amended my code to the following:


Private Sub cboBusiness_AfterUpdate ()
Me!cboBusinessUnit.Requery
Me!cboBusinessUnit.SetFocus
End Sub

Private Sub cboBusinessUnit_AfterUpdate ()
Me!cboLocation.Requery
Me!cboLocation.SetFocus
End Sub

Private Sub Form Current ()
Me!cboBusinessUnit.Requery
Me!cboLocation.Requery
End Sub



I want to cascade down from Business, to Business Unit to Location.


Can anyone advise me as to what I've done wrong here.

Thanks.

Cascade Combo Problem

Oct 20, 2005

Hello,

I have a question on cascade combos.

I have a form named Welcome and would like to add two cascade combo boxes.

The first combo, named cbolist get's its data from a table named QUERIES which has three fields:

ID
QUERYNAME
QUERYDESCRIPTION

cbolist displays the records contained in the QUERYDESCRIPTION field which are basically the name of other tables of my database with different records (obviously).

I would like that after selecting a record in the cbolist, the second combo, which I will call cboresult, will populate with all the records of that specific table selected in the cbolist.

Any help with the correct code?
Thanks.

Cascade Delete Query

Dec 7, 2006

Hello Friends,

I need some help to crete a query that will delete data in multiple tables.

My database has 5 tables. I store data in a main table and then append the ID and SSN to the other 4 tables.

The main table has also a purge date field that I will use to delete old records.

I use a form with a textbox where I type the starting date from which remove these records.

Is there a way or example I can see on how to remove all records at the same time. I have heard of cascade delete queries but really don't know how to use them.

My idea was to remove from the maintable all records with a date older than the date in txtbox and at the same time remove all records with the same ssn in all the other tables.

Thank you.

Forms :: Cascade Combos With Union

Sep 19, 2014

I'm trying to filter a combo based on the selection in another combo.The twist is that I need the row source of both combos to include an "*", "(All)" selection, as I am using these combos to filter a listbox. When I add the Union query with "*", "(All)", the row source in the 2nd combo is ignoring the where clause.

After making a selection in the Comp combo, the Emp combo should be filtered. It works with no Union in the row source, but does not work with the Union in the row source.

Cyclic Cascade Update? DB Design Question

Jul 12, 2007

Is this scenario considered bad design form? (see attached image)

I'll never delete a Customer or Site for whom a a Job exists. I need historical data to remain intact. I'll just mark a Customer or Site as [InActive] so they can't be used, when appropriate.

If the relationships are considered good form, then what is considered good form when deciding upon which relationships to set to Cascade Update? Do I even need to update autonumber foreign keys?

On upsizing this database, SQL complains that this arrangement is a cyclic update and won't create the relationship unless I tell it to use Triggers. This leads me to question whether I'm correctly using Cascade Updates in my Access db's.

Thank you.

Tables :: Simple Cascade Update Not Working

Oct 29, 2013

I've done this tons of times, so I don't understand what's happening... The title says it all: when I update the ID of one record of the main table, the referenced records on related tables won't update even though they have a relationship between them with the option "Cascade update" clicked.

In the attached database, the main table "Expedientes" is related to table "Actuaciones".

Forms :: Making Cascade Combobox With 4 Comboboxes?

Dec 2, 2013

I want to make a form where i have 4 comboboxes in a cscade combobox thing.

I already made 4 tables with info.

- My first table contains devices:

- ApparaatID (Primairy key)
- Apparaat(with 4 entries)

- My second table contains if it is hardware or software:

- TypeID (Primairy key)
- ApparaatID
- Type (where I entered hardware and software in 2 different entries)

- The thirt table contains operating systems:

- OSID (Primairy key)
- ApparaatID
- TypeID
- OS_versie (where I entered all the OS I want to enter)

Now I made a form I called problemen with 4 comboboxes.

- cboApparaat
- cboType
- cboOS
- cboProbleem

1) What I want is that when you select device 1 and 4 that cboType can select both hardware and software but with device 2 and 3 you can only select software.

2) If you have selected software is cboType I want you to be able to select 1 of the 11 OS I have pre-entered in the table.

3) That you get specific problems with the previous made choices. For example if you select Hardware in cboType, thta you only get problems with hardware to select from and the same with software and OS.

4) I want a textbox, that will contain the solution of the problem you selected and that if there and several solutions that you get all of them at once.

Referential Integrity: Cascade Update Not Working As Expected???

Nov 2, 2006

Hi,
I have a database with a couple of tables. The primary table has a primary key called "StaffNo". I checked the relationships between the primary table and each related table, if I have ticked on the boxes for referential integrity, cascade updates. All done. If I now create a query, which selects the primary table and one related table and enter a new StaffNo, I would expect to see the new StaffNo not only in the primary table but also in the related one. But there is nothing. Do I expect wrong? Have I missed sth.? I read a few posts in this and other forums reg. referential integrity, but I have no clue, what's wrong. :confused:
Any quick help is much appreciated.
Thanks :)

General :: Cascade Combo Boxes With Duplicate Values

Jan 18, 2013

I'm trying to Identify a particular entry in my table for editing via combo boxes. The same serial number will come in multiple times but a different job number each time it comes in. To identify a record for editing I need the user to identify the serial number in combo1 and then the job # in combo2 (cascaded combo boxes).

The issue I'm running into is that combo1 has dozens of serial number duplicates (combo2 is acting as it should). When I change some settings around I'm able to get combo1 to eliminate duplicates but now combo2 only shows 1 job # when there should be dozens for that serial #. I need all like serial numbers to show their job # in combo2 and I have not had any luck surfing around the net/forums/experimenting.

I'm pretty sure I have to use a Junction Table but I haven't messed with that and I'm not 100% sure that's the best/only way to do it.

Tables :: Invalid Field Definition - Not Able To Set Up Cascade Update

Jun 9, 2014

(named: Invalid Field Definition - Unable to set up cascade update but I have done what the moderator advised and have not been able to fix a very similar problem.

I have planned a database and must adhere to the plan or change it and basically I initially said that I would like to enforce referential integrity to synchronise my tables and I would also like to cascade update and delete to save input time because changes will be automated between table (where fields are connected.).

I have attached a plan I did if that makes the purpose of my database clearer.I have attached my database and have established the relationships* without referential integrity enforced I would like between my tables but don't know how to make them one-to-many relationships nor can I enable cascade update or cascade delete or enforce referential integrity.

I am new to databases (and to this forum) and have been promised by my line manager that I won't have to specialise, I don't think I have created the relationships but they are supposed to be between Vehicle ID and Hire Number, and Customer ID and Hire Number.

Can You Define 2 AutoNumbers In Access?

Dec 5, 2007

Hi,

I am trying to create a db for software change requests. I have defined 3 tables:

PCR - Change request table. This table contains all info on the software bug.
Release - Software release table. This table contains info about the release date, platform i.e. SAP
Sponsor - The person funding for the change to take place. This table contains info on the sponsor such as Name.

I have identified that I need a one-to-many relationship between the tables. For example, A release will have many PCR's. A sponsor will have many PCR's they are funding.

My Primary keys are: PCR Table - PCR_ID, Release Table - Release_ID, Sponsors Table - BPM_ID.

In order to get a one to many (the many being on the PCR table) I have put two foreign keys in the PCR Table (Release_ID and BPM_ID). Both of these keys in thier own tables are autonumbers. From my undertstanding to get MS Access to relate the data I need to set the foreign keys in the PCR Table to autonumbers. Or do I? I do not want to change the primary keys in the Release and Sponsors table to datatype number as this would mean user manual input which I am trying to avoid.

Thanks in advance for the help.
