how to get records into oracle database delete from db & update the records i have successfully connected my vb 2008 win form with oracle 10g.
View 1 RepliesHow would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

I'm trying to delete a number of records in a table from the last and forward. My idea is to use sql like this: delete top " & variable & " * from table where ID = something It gives me a general sytax error. Is it at all possible? Fuga. Edit: I also have the order by statement there. I just forgot to put it in the question.

View 3 RepliesI'm creating an application that adds and deletes records from a microsoft access database. The language I'm using is VB2008. I am importing the database through a wizard. I can add records and delete records, but I cannot delete a newly added record without closing the form first. When i reopen the form, I can delete the record. Here is how I have my database setup:
'Bind user info to the controls.
AUSERDataSet = New BulldogUsersDataSet
AUSERTableAdapter = New BulldogUsersDataSetTableAdapters.UsersTableAdapter
AUSERTableAdapter.Fill(AUSERDataSet.Users)
' Setup the binding source.
AUSERBindingSource = New BindingSource
how to do it, but the tutorial is not applicable on the program that I wish to do. The tutorial tells you to add 4 navigation buttons so that you can navigate the database(first, last, back, and forward). Then an update and delete button. But if this is what I will do, it would take 10 years to navigate the database and update a record. Now, what I want to do is just for the user to input a unique ID and click search button(which I have already done). Then the update would be easier. How can I update or delete a record using this method?
View 1 RepliesI 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?

View 1 RepliesI have a project that I am working on that requires me to delete records from the database if they are atleast 3 years old.I have something like this in DB2 SQL to get the date:
SELECT * FROM tableA
WHERE ADD_DATE < CHAR(CURRENT DATE-3 YEARS)
ADD_DATE is stored as Characters in my system, this is why I am converting I know it is also possible to get the date and format it in VB.net which is the language I am using to call the SQL statements.My question is whether it would be faster/better to get the date and perform the conversion inside the SELECT in SQL or would it be better to get the current date and convert it in VB.net and then use that date in the SQL statement. I'm thinking VB.net would be better because there are thousands of records that must be compared. I should be able to set it up in VB so that it only retrieves the date and converts it once but I am not sure what kind of performance hit each takes from these statements.
