Increment A Entry In A Sql Table Via Asp.net By 1?
Apr 1, 2011I have a database containing usernames and "points". I need to increment the "points" at will. I have the table connected to a sqldatasource.
Here is my current code:
With Users
.UpdateCommand = "UPDATE Users SET points = points + 1"
.Update()
End With
This works great, except, instead of just changing the entry with the username specified by a QueryString, it changes all of the entries and adds one.The sqldatasource has the following select command:
SelectCommand="SELECT * FROM [Users] WHERE ([username] = @username)"
This command makes it so that only entries with the querystring specified username are displayed. This is really my first attempt at SQL.

As you can see from the above code, that most of the textboxes are cleared so that a enduser can insert his or her values and information. Currently, I do have the OrderNumber which is the primary key cleared, however, I would rather have this field auto incremented to the next digit. For some reason, at the moment, I just do not know where to begin to set this field so that a digit canbe inserted and incremented rather than cleared.

Transferring Data From One Field In A Table In A Database To Another Field In A Different Table But Same Database In .NET?
Jul 22, 2010I am creating a database in VB.NET for a movie rental place. I currently have three forms;
Member Information
DVD Information
Borrow DVDs
What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;
INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb]
SELECT [Member Information].[Member ID]
FROM [Member Information]
but that has been coming up with error codes and completely not working.
Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?
DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?
Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?
The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.
