Delete Queries: Two Questions
Oct 3, 2005
Hey guys, I got two questions about delete queries,
Question 1: Is it possible to use the delete query to delete records from two different tables? What I'm looking at is deleting a customer from a customer list, and customer records from a distribution list, which are in two different tables. If not, is there an alternative way to accomplish this....ie write two queries but use macros somehow?
Question 2: I would like to add an "Are you sure?" message-box type feature into the delete query so that the user has the ability to think and back out if neccessary. Any suggestions for accomplishing that?
Thanks,
Chris

I have two tables containing (let's say for simplicity) questions and attachments (pictures). I am trying to perform a union query to join all the questions and pictures into one report, but it won't let me union the attachment because 'the multi-valued field 'TableA.Pictures' cannot be used in a union query'.
I have searched and searched for a solution (and got kind of close) but i still can't get it to work. The best I can do is union everything like below, which gives all the questions as desired, but says #Error in the pictures column:
SELECT TableA.*
FROM TableA
Union
SELECT TableB.*
FROM TableB;
(Note tables A and B have the same structure, several yes/no and open text questions as well as one attachment field. )

I have two queries, both delete from the same table and both have joins..This one works:
Code:
DELETE RequestCheck.*
FROM(
SELECT TOP 3 PayRequest.RequestID, PayRequest.GBPAmount, PayRequest.Currency, PayRequest.RequestDate
FROM PayRequest
WHERE (((PayRequest.Currency)="EUR Euro") AND ((PayRequest.RequestDate)>#11/16/2014#))
ORDER BY PayRequest.GBPAmount
) AS TOP3 INNER JOIN RequestCheck ON TOP3.RequestID = RequestCheck.RequestID
WHERE (((RequestCheck.CheckID)=8));
This one does not:
Code:
DELETE RequestCheck.*
FROM 300_tblDeleteRequestCheck INNER JOIN RequestCheck ON [300_tblDeleteRequestCheck].RCID = RequestCheck.RCID;

Is it possible to delete records in a table if it has no matching records in another related table by using a delete querie. I can find plenty of info on deleting matched records but nothing on unmatched.

Im pretty new to database structure, terms and whatnots. Im developing a database for my organization solely based off of my limited knowledge of coding structures and languages. The question may seem a little novice, and just wanted to preface it with that 8)
Delete Queries seem to delete records based off of certain criteria. The question is this: Is there any way to use a delete query to delete a COLUMN in an entire table rather than a record? I dont even need criteria to be there, im basically importing information from an excel spreadsheet that is a common format for our organization and trying to remove info that isnt pertinent to our portion of the business. So basically theres a few columns that really just dont make a difference to us.
Any help would be much appreciated. Thank you!

I got these two append and delete queries in my database that i want to run on startup. I was wondering if there is a way to not have the msg that pops up to ask if you are sure you want to append/delete 0 record to table if there isn't any record that matches the condition set. I'm sure there is a way because if there isn't any record that matches the condition set in the queries then i don't want to have to click "No" everytime the database starts.
thanks,
Vincent

When this query runs I want the popup parameter to open and ask for an ChID number. User enters that number and it deletes that record. I cant figure out what to enter on the criteria line. I have [ChID] and that wipes all records. I tried = [ChID] and it does not run.

I need to delete duplicate rows (or create new table without them) but the duplicate is not the entire row of data.
Date Time LeagueMatchingId League HomeMatchingId HomeName AwayMatchingId AwayName
HomeScore AwayScore HomeRedCardCount AwayRedCardCount FTOU FTOverOdds FTUnderOdds
20121202 10/02/2014 20:34:02 17 FRANCE LIGUE 1 147 Lorient 154 Toulouse 0 0 0 0 1.5 0.88 -0.98
20121202 10/02/2014 20:34:02 17 FRANCE LIGUE 1 147 Lorient 154 Toulouse 0 0 0 0 1.5 0.88 -0.98
[Code] .....
In this example I am only interested in the first and last rows, since the ones in between have the same data in the last few columns. They are not true duplicates since the time stamp for each is different.
Currently thinking I need to compare each and every row to the prior row in VBA and delete if criteria match.

I'm trying to delete data (no archiving required) from 5 tables that all have a one-to-many relationship between them and keep getting the following error: "Could not delete from specified tables".
I've tried everything I can think of including the following:
* Set unique records property to 'Yes'
* Enable referential integrity and cascade delete records in the relationship diagram
* Checked the DB isn't read only
* Have correct permissions to delete records
I'm the only person in the database but I'm at a loss and short of me actually deleting the 23891 records manually I can't think of what else to do!

Okay I have 2 tables and I used queries to filter and delete the info off those tables. Now I combined the 2 tables by using a query which is query 1. What I found was a few cells that are blank cells.
I tried creating another query based on query 1 from the 2 tables to try and delete it but it won't work. I tried everything and nothing seems to work. I can't filter the data since I am creating another query called query 3 to display the final results.

I have a delete query where i want to delete only the row that contains the max value of the IDnum field from the table STM, where it links two tables on CellTell
I currently have this:
DELETE DISTINCTROW STM.*, STM.IDNum
FROM dpl_00c_tbl_StmCellDups
INNER JOIN STM ON dpl_00c_tbl_StmCellDups.STM_CellTel = STM.CellTel
WHERE (((STM.IDNum)=(select max(IDNum) from `STM`)));
It doesn't want to throw out any values when i run it, or view it.

I have two tables as follows;
Master file:Vessel_master
Vessel_code
Vessel_name
main data table:Main
Vessel_code
container_no
size
Voyage
weight
by using above two table have made a query as follows;
Vessel_name:Vessel_master
Vessel_code:Main
container_no:Main
size:Main
Voyage:Main
weight:Main
Have joined "vessel_code" fields of the both tables by join type 2.
by using the query as data source made a form to edit/update/delete data. the problem is, when delete a record by using the form, it will delete the related data in the master file as well, which i do not want.

I have a cancelled service that gives a -1 to an ISCANNED field for each EventDate after the date the services are cancelled. Now I am permitted to Delete all of the cancelled records except the Min() date that =-1.
I built a query to find the value for the First Event date that =-1. I then built a delete query to delete all records after the First Event date that =-1 but it had to Join the "Find the value of the First query" to get the table records to show the records that were going to be deleted.It cannot delete.
Is there a module or VB that can be used to make the delete query work without using the joined "Find the value of the First query"?Something that will say "delete all the records after the first cancelled record"

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!

Hi 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 have a Unmatched query that displays what I need but I want to clean up my database and remove them but its not letting me. See sql below.
Code:
DELETE Warranty
FROM Warranty LEFT JOIN Serials_Repair ON Warranty.[Serial] = Serials_Repair.[Serials_Repair]
WHERE (((Serials_Repair.Serials_Repair) Is Null));
I changed "Delete" it was "Select" thinking that would work but it does not.

Access 2010
I created 3 find unmatched queries from the query wizard. The first one works great. I can delete a record in the query and it deletes the record in the main table.
The second one allows me to delete a record and gives me the pop up box that says " you are about to delete 1 record". I click yes, but when I check the table or reopen the query the same record reappears.
The third query does not even give me the option to delete.
I can create a regular select query and delete the records form 2nd and 3rd but not from the queries made from the unmatched wizard.
I am using the same fields in all 3 queries.
I do not have enforce referential integrity or the other 2 options checked in the relationship properties. (not sure if this makes a difference.)
I even tried to redo the unmatched queries but I get the same result for all 3.
I want to be able to delete the records in the other 2 queries.

I am trying to create a query to find duplicates and delete the duplicates. The result will eventually be used in another query (append query) to update a table.I have a table with 4 columns lets say for simplicity they are A, B, C, D
I want my query to find duplicates within B and deleting them. The catch is before deleting them I need to look into column A to ebsure they are actually duplicates. Example below
Example
A B
John Doe Tires
John Doe Wipers
Allison Doe Tires
Allison Doe Tires
As you can see from the above Tires is a duplicate and need to be deleted.
A B
John Doe Tires
John Doe Wipers
Allison Doe Tires
