I have to delete on a monthly schedule from a few Tables a lot of Data (> 20.000.000 Rows). So I was thinking instead of "just" delete the items, I would like to run the delete Statement Asynchron. I already wrote a little function with help from the "F1" Button ;-). But so far no luck. So can somebody point me in the right direction or point out, what I'm doing wrong here? [Code]
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
