What I'm trying to do is making Cascade update and delete between two tables. For example in my case I have Field called Full name in table1 and I want the same field in table2 that will update when something is added in table1 and vice versa. I have tried relationship but I got an error that those fields does not have any unique value.
View RepliesHello 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.
How do I delete duplicated records without having to make a new table? I would like the records deleted from the original table.

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.
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".
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 :)
(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.
I am accessing an oracle database that has several thousand records in it. I am quering for specific requirements, but would like to save my query results in a local access database for faster searching capabilities. Is there a way for me to set up a query that will go out to my oracle table files, select the records that pertain to my search criteria, and add records to locally stored tables without duplicating itself each time that I run the query? I would appreciate any assistance in this matter. Thanks for your help!
View 1 Replies View RelatedHi guys,
I was wondering if someone could help? I am using Access 2002 and I am struggling to find out out how you can insert/update/delete records through a form using the design view. Is this possible or do you need to do this another way?
Could some one point me in the direction of a comprehensive tutorial or outline some instructions for what I need to do?
I need to create a form that inserts people's details into a table
When user types in a surname as a parameter query, up pops the form with the details of the person stored in the database, and the user can update the details through the form and the details are saved to the table they came from.
Thanks in advance!
I'm a newb to Access and SQL and database management. I have a main table and a dependent table with a 1 to 1 relationship, relationship integrity and cascade update and delete. I used an append query after I had modified several records, and after the append deleted one of the records from the main table. It remained in the dependent table. Access didn't catch the disparity even after a restart. I broke the link and tried to reestablish it, and of course Access wouldn't let me. I deleted the record manually from the dependent table and all was well.
Why would referential integrity/cascade delete not be recognized after an append query?Access 2010.
This is the second time in two days that cascade delete has been broken in two days after using a query on the main table. Yesterday, after referential integrity was broken, deleting the records from the dependent table allowed me to restore Cascade Delete functionality and it worked for the rest of the day.
I have a database that needs data to be reentered every school term, at the moment i am having to delete selected data fields manually. im looking to create a query so that the data is deleted by running it. The data would be returned to a blank field. I have tried using a delete query but it is asking for the selected table, even though a selected table exists. Using the update query i am faced with updating the query to a typed word however i just want it blank.
View 1 Replies View RelatedOK,
I know what records I need to delete, just not sure how to do this.
I have 2 tables.
My main table, and a child table that hold some additional info for that record.
What I've been asked to do is, delete all records where in the child table the records meet a certain criteria.
So first I created a select query, added my main table, and then my child table.
Added my criteria to filter out and found the records they want removed.
So I thought I could just convert it to a delete query and be done. Nope because of the relationship between the tables it would not let me do it this way.
So the select query shows me all the ID#s that need to be removed (194k worth of them). How do I use the data from the select query, to create a delete query to remove all the files from the maintable (which should delete the data from the child table because of the relationship?)?
Here is the select query, that found the records that need to be deleted
SELECT tbl_Edit_Type_IRR.Information, tbl_Edit_Type_IRR.Issue, tbl_Edit_Type_IRR.Review, tbl_Edit_Type_IRR.Main_ID, T_tbl_main.Main_ID
FROM T_tbl_main INNER JOIN tbl_Edit_Type_IRR ON T_tbl_main.Main_ID = tbl_Edit_Type_IRR.Main_ID
WHERE (((tbl_Edit_Type_IRR.Information) Is Null) AND ((tbl_Edit_Type_IRR.Issue) Is Null) AND ((tbl_Edit_Type_IRR.Review) Is Null));
Humm, been going over this and can't figure where I am going wrong.
Linked SQL server table.
SQL permissions are correct (cause every thing works via QA using pass through security).
Form with a CBO to select Item1, once selected list box populates with Items tied to it.
Select item from list box click button to break the tie between the two.
3 tables, Item1 Table, Item2 table and cross reference table that ties them together. The Break Tie basically (should) remove the entry from the cross ref. table. Form allows me to insert a new tie (same premis as break only allows you to select items not tied currently) and will insert a row into the cross ref. table. But it will not allow me to delete, or as a backup plan I tried to zero out the FK values. Delete says not allowed (bad permissions, table read only, etc.) and Update says must use an updatable query.
NOW the queries I have used are basically DELETE FROM CrossRef Where PK = nnnn OR UPDATE CrossRef SET FK1 = 0, FK2 = 0 WHERE PK = nnnn
I mean it does not get any easier than that.
So what am I missing on this? Why won't it let me delete/update that stupid table?
This stuff can sure be stressful. :)
Anyway!
This is all linked to a form, but it's queries I'm sure I'm having the problem with. I'm hoping someone can help me out here.
I have fields in a subform which I've got an update query running after the focus is lost on a field, and it puts these values in a table I created. I'll call this table A. This is so that I may run another update query on the form when this is done, and have it take the values from this table created and add them to a total in another. I'll call this second table B.
I know this design behind this is flawed because in theory I don't need the 'temporary store' (A), but it's in the design of the thing to show that the values are infact being stored. As I'm sure you can understand, in order to keep doing this each time I open the form, I need to clear A. Preferably on a button press on the same form so that I may have the totals all calculated on B and then clear A right after.
The problem I'm having is that I'm using a delete query on a button press, and instead of just clearing the fields I need it to, it's deleting everything in A. I should mention that in A I have an ID field which should be telling the update/delete query which records to update/delete from in the criteria. This is a problem because it's deleting all the records on the form as I have them linked to A.
Any suggestions?
Thanks.
I have two tables. PreOrder and Order Tables. When our customer actually order a product, I want all information of that product to move from PreOrder table and append it to Order table. Currently, my user has to run an append query to add the record from PreOrder and add it to Order table. After that, she has to run a delete query to delete the record from PreOrder table. Since our query is setup to run by date, and order number..My user has to type the same thing twice. Is there anyone out there know the easy way? Thanks in advance..
View 1 Replies View RelatedI need help with an update query. I download several data tables from SAP that I would like to join again in Access.

I am trying to create a table to show the parent/child relationships between assemblies, sub-assemblies and detail parts. The table I start with has 2 fields a "Part Number" and an "Indenture".
Please forgive all the periods, couldnt think of how else to seperate the values to depict the tables.
Example:
IND..PN
00....A
01....B
01....C
02....D
03....E
03....F
01....G
00....H
01....I
02....J
I can get the first step to completeing the new table of parent/child relationship like this:
PN....00....01....02....03
.A.....A
.B....."".....B
C......"".....C
D......"".....""......D
E......"".....""......"".....E
F......"".....""......"".....F
G......"".....""......""....G
H......H
I......""......I
J......"".....""......J
Where "" are null values
My problem is making it so that every part number has its own array, aka [family tree], so that for part "F" the table would hold "A,C,D,F"
I though an update query where for example:
*"Zero" is a single field string.
IIF([00]<>null(), Save [00] to Zero, Write Zero to [00])
Would work but have been unable to find any information about passing a field value to a variable for later use or comparison. I would have already done this in excel if the table had less that 65000 records.
Example of final table:
PN....00....01....02....03
.A.....A
.B.....A.....B
C......A.....C
D......A.....C......D
E......A.....C......D.....E
F......A.....C......D.....F
G......A.....C......D....G
H......H
I.......H......I
J.......H......I......J
Any help is greatly appreciated.

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.
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
Hello,

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.

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.
