Hi,
I need to remove all duplicate records in a table. These are records that have matching Contract and Order fields. I can't do a DISTINCT query, because that still leaves one record. Thanks.
Michael
Can anyone suggest a way to remove duplicate records.
I've come up with this:
SELECT *, count(*) cnt FROM tableName GROUP BY fieldname1, fieldname2, .... HAVING cnt > 1
But this does not fully resolve my problem.
Thanks.
I have a table which has duplicate records so I want to write down the code so that when the user click on a button then it should remove the duplicate records from the table.

View 1 Replies View RelatedI have this small database, I would like to have your support to setup this query "QryResults" in order to remove the duplicate records, I can't find a way to get shown only true records, for some reason I'm getting duplicate rows and fake values, the query is calculating operations from two different queries and a table.
View 3 Replies View RelatedI am using information pulled from a separate database to create a new database for mail merger purposes. I have created delete queries that go out and delete specific records from the new database to help us get the proper list before setting up the mail merge. However, now I am stuck. We have customers that have multiple accounts with us that are qualified for this mailing, yet each customer needs to receive only one mailing. The table looks like this essentially. Table 1id statCode acct custNumber* addy-etc. *This is the field in which we can find exact duplicates. What I need to do is remove the duplicate entries and leave at least one of the entries within the table. It does in fact need to remove the whole record, but as I said leave at least one of the records behind. Can someone please help me to find a solution to this. I guess I should add that I am not very good with Access and I use it very sparingly. I assume that the above can be accomplished using a SQL statement. Any help will be greatly appreciated. LR**EDIT** I also needed to add that I do need to exclude 000 00 0000 from being removed because of duplication.
View 6 Replies View RelatedHi all,
I have imported a table from Excel. The table contains a long list of names and there are quite a lot of duplicates.
How do I remove the duplicates so I can import the clean list into a value list in Access ?
Thanks in advance !
I am using Access 2007, and I mistakenly created a duplicate table in Relationships. And, I have not been able to removed it or delete it.
View 6 Replies View RelatedI am attempting to filter the data in query design such that it will not return anyone in the database has there name present more than one time.
For example, in the image below under the Owner_Name field there is "Abbot, Mark C Etux Wanda C". This name appears twice in the database. My criteria is the name can only appear once, therefore this record would not be returned after the query. In query design I would like it to return only name records that appear once in the entire database if there is a way to structure that.
I have a competition ranking contestants. A contestant can compete multiple times, each time with a unique registration number.
I am trying to sort by score to rank the contestants, however the contestants can only receive one rank - their highest score (not a sum of their scores, only one score). ? ?
Example:
Registration Name Score
2345 Sally 247
3456 George 230
4672 Sally 255
What I want to see:
4672 Sally 255
3456 George 230

I'm having difficulty with the syntax in this query to remove duplicate data for the field "StocktransID".
Code:

I have two tables in my Access database. Table 1 has three columns, First Name, Last Name and Phone Number. Table 2 has just 2 columns, First Name and Last Name. What I would like to do is write a VBA macro to consolidate Table 2 into Table 1 and insure any duplicate First Name-Last Name combination is removed.
Table1
Code:
F.Name L.Name Tel.N.
John Smith 12345
Larry Miller 12344
Tony Woods 12333
Table2
Code:
F.Name L.Name
Albert Black

Issue: We are trying to remove duplicate information for one fiscal year in an ODBC then import and append the correct information from an Excel spreadsheet. The process we have followed is
Copy Master Access file and paste new file (to test, so we do not loose original data)Rename new file TEST.accdbCreate a delete query for Fiscal Year dataDelete information for duplicated Fiscal yearImport correct Fiscal Year information to a new table from ExcelAppend table to master table (ODBC)
Questions:
After being granted permission to delete information, it worked once and now no longer works. When the permissions are reviewed it appears that everything is still granted but the following message is received:
Why does Access change all copies of SDA, even if filenames are different and in different folders?
When we append table, why does it duplicate information?
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.
:confused: I am importing a file from excel into access. The table has about 6300 records. Some records are duplicates or even triplicates. How do I write a querie to leave only 1 of of these records and rmove the duplicates.
Second, I will be importing new files weekly that after I do the above I will need to append to the first table and then remove duplicates. How dod I do this.
thanks
I have built a qry that initially shows the correct information. For example.
tblContent has 289 records with a Type = Class.
I built a Query to select from tblContent Type = Class and I get 289 records. I add additional criteria of Progress <>"Not Scheduled", I then get 206 records. I then add additional criteria Last Name <>"Demo" And <>"Care" And <>"Support". This brings up 200 records, but the query appears to duplicate each record 3 times. I do not have 3 of the same types of records.
The SQL Statement is below
SELECT tblProfile.LoginName, tblProfile.FirstName, tblProfile.LastName, tblProfile.Organization, tblProfile.CostCenter, tblContent.Title, tblContent.Type, tblContent.Code, tblContent.[Date Assigned], tblContent.[Date Started], tblContent.[Last Accessed], tblContent.Progress, tblContent.[Date Completed]
FROM tblProfile INNER JOIN tblContent ON tblProfile.LoginName = tblContent.LoginName
WHERE (((tblProfile.LastName)<>"Demo" And (tblProfile.LastName)<>"Care" And (tblProfile.LastName)<>"Support") AND ((tblContent.Type)="Class") AND ((tblContent.Progress)<>"Not Scheduled"));
The qry is named qryPhysical Class. I have provided the link to view the database. Can you help me?

(Been a while since I had a question.) I have a table that stores a list of paper forms. the fields are ID#, display name, doccument name, and a code to determine if its a Word or Excel doccument, or an access report. Works fine; the user can click a form name (on the Forms/Reports tab on the main menu form) in a list box, set the # of copies and print the form. There are cases when a group of forms is needed (client admission is one). I have made a group table containing: GrpID, Grp Name, formID. I would like my "Form Group Edit" form to have 2 list boxes; the left one containing the (short) list of available forms; the right one displaying what forms are already (if any) in the selected form group. My idea is to have add/remove controls to manage the right list. I know this "wheel" is already invented and would like to plagerize one that works. Thanks in advance for your help.

I have a Datasheet view of a form and it displays a "+" symbol. When expanded it returns a list of related records. How do I get rid of the "+" in my form?
View 8 Replies View RelatedI have two tables, one is of departments, and one is of people (with a FK denoting what department this person is in). Now consider the fact that there are duplicates in the departments table, and I would like to remove these duplicates. However, the duplicates have related records (in the people table). So, before removing the duplicates, I must update the FKs in the table of people (this is the step I'm having trouble with).
Here's an example:
As you can see, the "Sales" department is there twice. And both have a related record. What I want to do is:
Update all DepartmentIDs (in tblPeople) to not point to duplicate records. In this example, that would be PersonID 2; Joe. His DepartmentID should update to "1" (as both "1" and "2" are "Sales").Delete the duplicates in tblDepartments (in this case, DepartmentID 2, "Sales").
The second step is no problem, it is only the first I am struggling with.
Also, the example posted here is just an example, the data I actually need to do this for is significantly more complex and there are many more records! In the attached database:
qry1: Simple query to find all duplicates (just used the query wizard)
qry2: Just the first row of each duplicated departments (duplicates that shouldn't be deleted). In the example above, this would be the "2", "Sales" row in the tblDepartments table.
qry3: Basically all qry1 rows that don't appear in qry2
qry4: All qry3 values, and their respective qry2 value.
This is what each of the (soon to be deleted) duplicate values' related records' DepartmentID should be updated to... There's no simpler way to phrase that, so using the example above, qry4 would return "2","1". This indicates that all people with a DepartmentID of "2" should be changed to "1" (so we can subsequently erase the department with the ID of 2.
This is as far as I have gotten. My next step is: Update all FKs in tblPeople based on qry4 (You can't set an update query's criteria to pull from another query, nor can you use the second query for the update value... or maybe you can, but I don't know about it).
I have table call "empTable" and it has an Attachment field called "Attachment". Some of the records has empty Attachment field and some record has one attachment and some has two and the attachment types are jpeg and pdf.

pls can someone point me in the right direction
