General :: Records Being Deleted In A Related Table When Not Supposed To
Jun 13, 2014
I am losing records in one table when I delete from another, i.e., I do want to delete records in one, but the related records in the other are also being deleted. This was not happening until I did a recent up date.I created a database in Access 2002 about 8 years ago and my client has been using it successfully ever since. I have occasionally made updates and enhancements. They have over the years upgraded and are now on Office 2010. I'm still using Access 2002.
I recently (3 weeks ago) added a new feature and installed the new code. The database is split, code and data. The new feature was working well, but suddenly they were losing records and they cannot operate until I have it resolved. I spent 2 hours today in their office and could not work out why it was happening.
I have a straight forward client table with names and addresses and some other information. I have another table which links together Clients, Counsellors and Supervisors and works out a room allocation for Therapy sessions. Once the Therapy sessions have been completed, we need to delete the Client, Counsellor, Supervisor + room allocation, but we do not want to delete the Client record in the Client table. The User is offered the opportunity to either archive the client record or not archive it, that's all. The Archive procedure is simply to put a tick in the "Archive" field, not delete the record.
However, when the Client, Counsellor, Supervisor + room allocation is deleted, it is also removing the Client record. I do have a relationship between Clients, Counsellor, Supervisor, but it doesn't have "enforce referential integrity", it is just a one-to-one relationship. The odd thing is that when I delete the allocation here at home on my Access 2002 system, it does not delete the Client Record, but it does in their office, using exactly the same code and data.
The Allocation is on a sub form and the way they delete is by highlighting the Allocation and then clicking on the X - Delete button on the Access menu (the program is not very sophisticated, but has worked until now). I have some code in the "on delete" event, but even if I take out all the code and just allow the deletion with the usual Access message "you are about to delete 1 record... " I have seen that the related Client record gets deleted at the same time. it does not happen on my system, only in their office.
Many sessions can have many employees - thus the joining table has been included.
When trying to delete an employee from the database using a form, I encounter the error:
The record cannot be deleted or changed because table 'tblEmployeeSessions' includes related records
Is there a problem with my table relationship structure? Or is it 'correct' that as the employee is supervising a session he/she cannot be deleted as this would interfere and maybe mess up the session record?
I have a report that when displayed should show information from various forms. On my report design I have 3 subforms, which the report is pulling data from. The strange part is that each record displayed in the report shows the same information over and over 16 total times. I was thinking it was some kind of grouping error.
I'm getting an import error that records are being 3 records being deleted and one lost due to violations. However when I go back to check the data that was imported I can't find anything missing. Any clues on what could cause the error but still import the data.
I created a simple database with a single table and a form so I can track patients enrolled in a study. I added a few test records to make sure everything was working properly. Now I'm ready to use the database for real. Only trouble is, when I erased the test records I find that I can't add new ones.
I've always used an audit trail for tracking changes of records that already exist but I have had a situation come up where I now need to track records that have been deleted. For example, if I delete a record in the datasheet view.
I've seen several examples how to do this, with the most common seeming to store the data into a temporary table while waiting for the delete confirmation. If I am reading the notes correctly, it's done this way to capture occurrences when multiple records are selected to be deleted. Is this the best approach for this type of task?
I am looking for a query that will return records from a table that have related records in another table. Opposite to the Unmatched Query Wizard.I have two tables: tblSupplier and tblSupplierProducts.The two tables are related by the field "SupplierId".I need the query to only return Suppliers that have Products.
I have a table that I am importing from FOXPRO DATABASE. When someone goes into the system and deletes a record, Foxpro does not really delete the records but marks it for deletion. There is no field to query on that I can see in the table, but when I go to Foxpro the record is "marked" for deletion.
Anyway to exclude these records when doing a query or importing the table?
I have a table called tblCompanies. When a company acquires another company, I need a method by which the acquired company's CompanyID (PK) can be updated to the new company's CompanyID (PK). I also need to be able to update all related CompanyIDs (FKs) to the new value in related tables.
In cases in which the new company does not have an existing record, there is no problem: the company name simply gets changed to the new company and the existing CompanyID is maintained. I then use an audit table and Track Changes function to keep track of the company name data and a union query to keep the old names in the selection lists.
The problem is when both companies already have existing records in the table.
So, let's say I have records for Company A and Company B. Company A merges with Company B and Company B is now the main record. What is the best, simplest and easiest way to update the CompanyID (PK) from A to B and change the CompanyID (FK) to the new value in all related tables?
I am envisioning a pop-up form that directs the user to select the new company and then an update query happens behind the scenes... but exactly how does the criteria for the update query get selected and how do all the related tables get updated? My vba skills are pretty basic, will I need extensive coding to do something like this?
Hello I need to add daily records to a related table using a form, from a button or subform displayed on a form updating the master table. This would enter the related key to the new form ready for insertion etc. Can this be done?
Hi, I've been trying to get this for ages now - both in the design view and in sql:
I have 2 tables - one called DrawingsRegister and a related one called DrawingRevisions. Each drawing has one or more drawing revisions. I want a query that will show each drawing (just once) that has more than one revision:
I have two tables to track our engineer visits, one tracks the visit as a whole and the other tracks the individual instruments the engineer worked on during that visit. This way I can track visits to customer sites separately to the visits made to an individual instrument.
Right now, I create a visit and then add Visit Lines (containing the details of the instrument visited). These instruments, or 'Visit Lines', are being displayed in the Visits Table via a related items box. Visit lines are associated with Instruments in the Instrument Table via a serial number lookup. All this works great...
However, I want to display both the serial number and the instrument description in the related items control in the Visits Table. Since the Visit Lines table only has the instrument ID lookup and not the instrument description I can't display it in the control.
I need to either:
a) Create an instrument description in the Visit Lines table as a lookup and have this automatically pull in the description based on the serial number the user selects.... which I can't figure out how to do - it's just an autocomplete.
b) Create an instrument description in Visit Lines and have a macro grab the corresponding description from the Instruments table based on the serial number input - but just for this record...
I have a table that has the list of "Project design" choices, and I enter in there the choices that a project can be. I then have that table related to a junction table that has the "Project design choices" linked to the "project code." Anyway, I THOUGHT that one of the bonuses to using Access was that if you see something spelled wrong, you could fix it in one table and it would fix it everywhere. However, when I see that I spelled something wrong in "TBLProjectDesignChoices" and I want to fix it, it tells me that I can't because it contains related records.... ok so, if this is bad design.. I may have to leave it because I have spent countless hours doing data entry for this..
I have 2 tables. 1- customers table with 2 fields : customername,customerno 2-conversationstable with 4 fields: date,customername,customerno,details
The conversations table is for keeping memo of telephone conversations with the customers.
I built a simple form deriving from the conversations table. And added to it a combobox with 2 columns from customers table to select the customername an customerno for the form.
While deleting the record in the conversations table,through the form, I saw that the customername and customerno in the customers table of that particular customer record are deleted also. I made no links between both tables.
this works fine and i can search using a requery button
however as deptartments are stored in tbldepts
when i change the query to retrieve the dept name instead of number directly from the table and i try to change this on the datasheet subform it changes it in tbldepts instead?
how can i change what dept the employee is in (as in change the number in tblemployee - but display the actual name?)
OK, your gonna have to bare with me a little bit as its hard to explain and if any VB is given please add a few annotations as I have to explain everything i do in a report (doest have to be too detailed, just to make the code understandable :) ) and if it needs better clarification feel free to ask :), but basically, I have the following relationship set up:
At the moment, because of the way it is set up, I cannot create a record in the transactions table unless an income record is given for it (because tb_income (one) to tbl_transactions (many)) but the way I want to work is as follows:
If you have a look at the tables tbl_transactions and tbl_income and their link. The way I want the system to work is when a new transaction is made, a new income record in the "tbl_income" table would be made with the date (in tbl_income) being the date at that particular time and all transactions created on the same date would all go in the subdatasheet for that one record created for that date; and if another transaction is made on an alternate date (say 00:00am of the next day) another income record would be created automatically with the date being of that particular day etc.
My other problem im facing is that everytime there is a transaction created, I want the stock level(s) field of products in that particular transaction to be decreased by the quantity purchased of that product but i have no idea how to do so
I enter records into MS Access and then when I close it and reopen it, every once in awhile records that I entered previously are deleted. I am new to Access so it may be a simple problem such as saving the database but it is extremely frusturating when I enter customers into a database and then reopen it to find out voila half the customers I entered are not there. If anyone can help me it would be really appreciated. Thank you.
Hi everyone I have a problem that I have deleted some records from a table in my database and now after one week I need these records again. Can someone tell me how to get them?
We have a massive db and on one of the screens the users can scroll through the records and view information they can also add new records. When the users enter the new record and go back to it it has been successfully stored in the relevant table even on exitin the form via the exit button (DoCmd.Close). However from time to time when the user enters the new record and closes the for via the close form button the new entry is not stored in the table and seems to have been deleted or not appended to the table.
We have no idea why this is happening as it doesnt happen all the time just from time to time.
Can anyone help please or has anyone come across this before !
I have an application (http://users.tpg.com.au/mr_mod/east.zip) i have been given but forsome reason one of the queries isnt doing what i expect it to do. One of the queries "Count Cams" is supposed to be able to look at a particular job number in the imported items table and count the number of cams, this is then reported in the job data screen on the main form coresponding to a particular customer. Eg customer number 4 has a parts list where there are x number of cams used, but what happens os it counts the total number of cams irrespective of the customer.
Can anyone see the porblem , i have spent several evenings playing and cant seem to fix it.
In my simple database (attached), I need to mass duplicate Tasks and their Notes.
I have three tables: tbTasks (PK: Task_ID), tbNotes (PK: Note_ID), jtbTaskNotes (FKs: Task_ID and Note_ID). jtbTaskNotes is my many-to-many junction table that ties Tasks to Notes.
The main form (fmTasks), bound to tbTasks, has a subform (sbfm_TaskNotes) that displays notes associated with each Task. On themain form,you select which Tasks you want duplicated via a checkbox. The append query (quCopyTasks) will duplicate all tasks that have the checkbox checked. All good there. However, I can't figure out how to also duplicate each task's Notes.
I found Allen Browne's solution [URL] ....., but that only handles duplication of one record at a time, whereas I need to duplicate many records at a time (sometimes 10+ records). How do I go about duplicating multiple Tasks and their associated Notes?
Before you ask "why are you duplicating records?": There are times when tasks need to be re-accomplished and therefore need to have a new record. It's easier to duplicate records than it is to hand-jam everything again.
How to track deleted records? I have a database that users login to and it tracks which records they make changes to but I do not have a way to track a deleted record. I read online about doing like an archive of the record to a table that will hold the deleted record and that made the most sense to me.
A team id can appear in either team1 or team2 (depends on how the algorithm to compute who plays who calculates it).
I want to know how many games a team plays, so I wrote 4 queries:
qryTeam1Games: SELECT tbl_Fixtures.team1_id AS team_id, Count(tbl_Fixtures.fixture_id) AS games FROM tbl_Fixtures GROUP BY tbl_Fixtures.team1_id;
qryTeams2Games: SELECT tbl_Fixtures.team2_id AS team_id, Count(tbl_Fixtures.fixture_id) AS games FROM tbl_Fixtures GROUP BY tbl_Fixtures.team1_id;
qryAllGames: SELECT * FROM qryTeam1Games UNION SELECT * FROM qryTeam2games;
qryNumGamesByTeam: SELECT qryAllGames.team_id, Sum(qryAllGames.games) AS SumOfgames FROM qryAllGames GROUP BY qryAllGames.team_id;
Unfortunately, if the same team_id and games combination appears in both qryTeams1Games and qryTeams2Games, it doesn't bring 2 records into qryAllGames and the summed number of games is only half of what it should be.
Is this a case where a union query shouldn't be used? Is that how it is supposed to work?
A work around isn't a problem but this did have me stumped for a bit.
I've designed a DB in access which has a BackEnd and 2 FrontEnds (one person insert all the records and the others just keep inserting infos till the process is finished.The DB has 12 tables and we used it for about 6 months without having any trouble but recently (2 weeks ago) i've add 3 new tables and then related them to one table that already exist.
The DB was running smoothly for a week after the changes but last monday (09/15) the "Record is deleted" appeared. I've compacted and repaired an the following errors descriptions appeared:
ErrorCode: -1017 ErrorDescription: Record is deleted. ErrorTable: tblFatura
ErrorCode: -1053 ErrorDescription: Index or primary key cannot contain a Null value. ErrorTable: tblFatura
ErrorCode: -1630 ErrorDescription: You cannot add or change a record because a related record is required in table 'TblExpense'. ErrorTable: tblFatura
I've restored the file via IT using the Backup2 days before the error occurred but after 30 minutes the same error appeared! I dont know if it is related to the new tables that i have add or no?
