Hello,
I have two related table: table_Company and table_contact. Now i have:
Table_Contact Table_Company
James Bolton -----------> MacDonalds
Hellen Kidman ----------> MacDonalds
Now, i wanna have one "MacDonalds" in my Company table, and delete the others "MacDonalds" and still have the relationship between my contacts and their company.
Good morning all!
I have a problem, I have a contact list table in my database such as name, addr, company, street, country etc. The problem is that I have multiple duplicates of the same data.
How do i delete the duplicates? Is there an SQL query that I can run to delete? How do I do it. Please help. Thanks a bunch!
I have two tables that have duplicate order numbers. I would like to compare the first table with the second and then delete the records from the second that match.Can I set this up in a macro and run it every day?
View 2 Replies View RelatedI'm wondering if it's possible to create a Query / Macro / VBA or whatever works, to detect the duplicate records in a table and delete them with the push of a command button. Or, even to do this automatically when the database opens using an AutoExec macro or something ?. I'd like for one copy of each record to be left intact in the table.
View 8 Replies View RelatedI am not too clear about why it happens. See following diagram:
My TBLItemID table is having several 1-to-1 related tables
I have enforced referential integrity and checked off Cascade delete related records
When I remove a record from TBLItemID the same row will be deleted from every one of the related tables
Yet when I go into any of the related tables and remove a row, via the 1-to-1 relationship I would expect that it will propagate through the whole web and remove the same row from every table. However that is not true. It will only remove its own record without touching any one else's.
How is cascading delete supposed to work? Does it work only when we remove records from parent table?

Have searched the forum but cannot find a suitable answer...
I have duplicates in my table that I need to delete but leave one existing record, e.g.:
ID Part Family Colour Cost
1 123456 HHH M98765 12.99
2 123456 HHH M64975 12.99
3 123456 HHH E79461 12.99
4 123456 HHH G13467 12.99
5 123456 HHH M98765 12.99
In the above example i would want to delete records 2-5 (based on Part and Family, even though the colours are different) leaving one there. If I run the find duplicates and then change that to a delete query then it deletes them all.
This needs to be done via a query as it is done in automation, so manually copying the table structure and applying primary keys to the fileds etc. is not an option.
Any bright ideas?

I have a list of projects and am creating a query that tells me their duration based on beginning and ending dates. These beginning and ending dates can be edited by the user, and frequently, there are multiple beginning dates. When I query the projects, instead of getting unique project numbers on the left hand side to create unique rows, I get many of the same projects with different start dates. I would like to use the FIRST start date only for every project and not have multiple rows with the same projects being counted multiple times.
Is there any way to delete the excess rows and keep the original row? I've read a lot about using DISTINCT and UNIQUE INDEX with SQL but it seems as though these are only available for tables and not queries. Bright ideas, anyone?

Help please!
I have a form (frmHalfTab) built on a table (tblHalfTab2) that has existing data in it. In the very near future, I will be uploading additional data to this table via excel cut and paste. What I want to do is search for and eliminate duplicate records that have duplicate data in TWO fields, (MemberNum) and (MBRDrug), so that if MemberNum is "10" and MBRDrug is "Zzz" for more than one record, the duplicated records need to be deleted, OR a check box needs to be checked automatically for all the identical records, the original and the duplicate(s). I wanted to put this behind a button, if possible.
Now, I have created a duplicate query that will find the duplicated records, but I'm not sure how to use it to get rid of the duplicated records or check the checkbox appropriately. Should I ditch this query and choose a different route, or am I on the right track? Thanks in advance for your help.:confused:

I have a table that has 1335 records in, and columns names, Title, First Name, Surname, Address, Address2, Town/City, County, Postcode.I want to know how to write a SQL code, which will locate all the duplicates that match the First Name, Surname and Postcode and delete them, but keeping 1 copy of the duplicate.I have created a query to locate the duplicate records, and I have put the SQL code there. I tried changing this, however it would delete all the records, so I am not to sure what to try...
SELECT SurnameSearch.Title, SurnameSearch.[First Name], SurnameSearch.Surname, SurnameSearch.Address, SurnameSearch.Address2, SurnameSearch.[Town/City], SurnameSearch.County, SurnameSearch.Postcode
FROM SurnameSearch
WHERE (((SurnameSearch.[First Name]) In (SELECT [First Name] FROM [SurnameSearch] As Tmp GROUP BY [First Name],[Surname],[Postcode] HAVING Count(*)>1 And [Surname] = [SurnameSearch].[Surname] And [Postcode] = [SurnameSearch].[Postcode])))
ORDER BY SurnameSearch.[First Name], SurnameSearch.Surname, SurnameSearch.Postcode;
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
The charity that I volunteer at has a web site through which they receive donations.
Most of the COMPANY names that they receive through their website are JUNK.
I would like to have a system to delete duplicate company names:
A = first programmatically delete all company names that are GOOGLE and this will remove about 60% of their spam
B = next group all Duplicate Company names, which will be removed manually
I know this probably has been asked a 1000 times but I don't seem to be able to edit the uncommented VBA-codes I found online to work on my database.
I already ran a query that shows me the duplicate records of my original table. Now I m looking for a way to
a) delete all duplicate records (not just specific ones by using a criteria) and
b) unite the unique records (result of a)) with the original ones that were not displayed with the "find-duplicates-query" ....
I need developing a new delete query criteria to add onto existing delete duplicate queries for deleting duplicate values. I need the new delete duplicate query to take precedent over the other two so that those values retained in the first query are kept retained after going through the second and third delete queries. Attached is a document laying out the request.
View 1 Replies View RelatedIn 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.
I have a table TO-det and another table DO-DET.The table DO-det will have details about all DO for each TOID record.Both have a common field name TOID The tables are related under ONE-MANY relationship.One TO-DET record can have many DO-DET record
Now I wanted to create a form where if i add a new record to TOID i must also be able to add data for DO-DET for that corresponding TOID.
I previously created 2 tables:
One lists all the stock symbols and company names = SYMBOL
The second table lists the purchase information for each stock = PURCHASE
I then created many queries, etc. using this data. Symbol is the key link between the various tables, queries, etc.
NOW that I understand the lookup wizard in the data type, I would like to change the symbol field in the purchase table to a Lookup field. I, of course, receive a message. I am told to delete the relationship with the other tables. If I remove the relationships and change the data type, can I then replace the relationship with out damaging all the queries and forms?
I created 2 table that are linked to a link table so to get a many to many relationship.I have a table for locations and a table for parts.One location can have many parts and One part can belong to many locations, that is way the many to many relationship.
how to get values from the parts table to the Location table using the linked Primary Key in the foreign key linked field.The values also have to be interactive, if I change the value in the part table it needs to update in the location table.
What can I put in the field of the location table to get a specific value from the parts table?
I tried setting the field to calculated field and put the Dlookup function but that didn't work. The lookup wizard seems to be the solution, but I can only create combobox or list box and I need to select the value manually. I just need a value to be put automatically by looking at the foreign key.
If I put the Dlookup function on the default value, those it update if a value is changed in the part table?
I want to find duplicate records based on FirstName and LastName and delete the duplicate. Also, I want to delete any records which have a blank FirstName and LastName.
How can I do this?
Thanks,

Hello
Could you help me ?
My problem is :
I'm developing a ms database for the a "repair service" .
I created a table witch contains basic data from customer, including its unique ID number (key field), name and contacts ...
Now I need to store the "repair service" data from each costumer ( its time consumption, replaced materials...) in a separate table but, If I'm thinking well, I must have a table for each costumer so, I will need to link each individual "repair service" data table from each costumer to each costumer itself.
Do you know how to do this ?
Lots of thanks in advance,
Miguel
I have two databases, one containing the tables and one containing the forms and queries. The forms/query database is built from linked tables from the tables database. I would like to expand one of the fields from 7 characters to 9 characters. I planned on doing the in the table database, then updating the linked table. However, the table I need to alter has relationships with about 10 other tables and I get the (you cannot make changes to a related table error message). Is there a way I can make this change without deleting all the relationships?
For future reference, should the relationships have been created in the form/query database?
Thanks, N
Greetings to everyone,
I'm building a database which will generate work orders, and those have a opening date and closing date, besides that it has a work order number that is of the following format:
YYYY/ NNN (being the NNN the work order number in that year)
to create the number of the work order I'm trying to fill the WOYear field
with the year of the WODate field...but I'm not being able to do it...
How should I do it?
Thanks.
