DB/Reporting :: Delete Duplicate Record In Table Without Key?

Dec 12, 2010

I am working with some DBF database files and have an interesting dilemma. I need to search through a table, find duplicates and delete them. Problem... Table doesnt contain a key.

So Table looks like this:

Name, BadgeNum

I need to be able to find instances like this:

John, 10
John, 10

and then delete just one iteration of John, 10.

Is this even possible? A "DELETE FROM TABLE WHERE BadgeNum=10" will delete both.....

DB/Reporting :: Adding The First Record In A Self Referenced Table?

Mar 2, 2008

I have a self referenced table it contains Employee information, an employee reports to another employee, I've done this by including a field named ReportsTo as a foreign key that would be filled with the primary key. My first question is when using a strongly typed dataset how would I insert the first record without raising an error. the only solution that I could come up with is to insert an employee with the name NoOne and reports to himself i.e the employee number is the same as ReportsTo, this solution would be hardcoded in my program and only works when there is no records in the table. This is ok as long as I don't delete every employee from the table and try to insert new employees, in this case my insert will fail because the NoOne employee number is "1" and this would violate the index. this case calls for reseting the index each time I delete all the employees.

Nov 22, 2010

I am working with SQL Server express 2008 And visual Basic 2008. Here's what I'm trying to do, if it is possible.

I am using an Insert query to create a new record in the table. A sequential ID number is inserted into the database when the query is run in Visual Basic.

Coping The Active Record In A Form To Another Table And Then Deleting The Record From The Original Table?

Aug 18, 2011

I am leaning VB and have created a basic inventory app for work that consist of 4 tables, CurrentInventory, Surplus, Staff and Category. Each of these tables have a corresponding form. My question is with the CurrentInventory and Surplus form/tables. I want a button on the CurrentInventory Form that when clicked the current record would be transferred to the Surplus table and deleted from the CurrentInventory table.I am assuming that I could somehow use the INSERT command to copy the current record to the surplus table but I am not sure how to accomplish this.

Delete Duplicate Records From Combobox?

Apr 28, 2010

I currently have a sql database linked to vb.net and I'm populating the comboboxes using SELECT statements. However, I'm getting duplicate records in the comboboxes.I have my database setup as 1 project to many submittals and 1 submittal to many items.

I have 3 projects in my sample dataset and I'll recieve 3 duplicate submittals and 3 duplicate items.

If I have 6 projects in my sample dataset than I'll get 6 duplicate submittals and 6 duplicate items.

I've tried adding distinct to my SQL statement, but that didn't do anything. Is there any reason why its showing as many duplicates as I have projects?

Delete Excel Columns And Duplicate Values

Jul 5, 2011

I am trying to create a .Net application to edit a excel file by deleting some columns and keeping the columns which we need and then removing the duplicate values based on the first column which is going to be the Serial no. which should have a check to have 6 digits by default like 2563 should be displayed as 002563.

Code:
Public Function GetAllFileContents(ByVal path As String, ByRef errorMessage As String) As IList(Of String)
Dim contents = New List(Of String)
Try
Dim files = Directory.GetFiles(path, "*.xls")
If (files.Length = 0) Then errorMessage = "Please select the files"
For Each file In files
[Code] .....

I am trying to create something different by not only letting me do it for excel files but for say txt and csv files along with it. Removing all the values which I dont want and removing the duplicates and then if possible putting a check on the first column of data that the serial number number should have minimum of 6 characters and then The output file should have all the details in Uppercase
