I 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.

My problem is with the tickets table, I have listed the user that created the ticket, the tech who will solve the ticket and a user that over sees the ticket. All three users reference the users table. So how do I can I query the tickets table and get all three users that reference the same table storing the users?
Table1: Tickets
1) Ticketnumber
2) EnteredBy User 100
3) Issue
[code]....
What I can do now is something like this:
Select Ticketnumber, EnteredBy, Issue, UserName FROM Tickets INNER JOIN Users
ON Tickets.EnteredBy = Users.UserID

How can I update local dataset with mysql database without making duplicates. Assuming I set some column in mysql as primary key, which has unique string.
adapter.fill will just add duplicates, but adapter.clear before that is not an option.
So I want to update if the key column is the same with mysql data and if there is option for ignore adding new row.

Im trying to push (for what of a better word) the output of a button which is in a text box to a field within mysql. I have followed the tutorial on here for connecting to a mysql database. And I have also followed and it works the tutorial for getting data from mysql to a form. But I cant find anything on how to achieve the reverse of this - populating a field with data/text from a textbox.

I am trying to update a field in my MySQL database using VB.NET.....
Basically, I can read the field's content, using this code:
SQL = "SELECT * FROM `boomtable` WHERE `Tab1` = 'CLOSED'"
However, I want to update the Tab1 field to have the value OPEN if it's currently closed, and make the value CLOSED if it's currently OPEN.. Right now, it's CLOSED, (I put the value in manually when making my table)
Here is the code I'm using that changes my label based on the Tab1 field's value that works fine... Except I want to actually make it update the field in the database in addition to changing the label text.[code]...

I got a Mysql sql database for my project. The id field is set as auto increment, which seems to function correctly. But on the form in my text field and datagrid i see a negative number, while in the database its a postitive number. I do not really plan to use the id field right now, but when i do it might cause some problems.
Anybody know why it would show as a negative number on the form(textbox/gridview) and as a positive in the actual database?

I'm having a problem with a MySQL query for returning the "last visit" field in a table.Originally I had:select fname, lname, last_visit from patient where isactive = 1 and uid = 1Which worked perfectly in MySQL, but as soon as the query is executed by my ASP.NET app, it adds in the time field also to the date area. So 2011-12-12 becomes 12/12/2011 12:00:00 AMI tried this also, with no improvement:

I have done plenty of VB programming using flat files etc... Now I am attempting to create a SQL database (I have my sql 2008 express box up and running) I can connect just fine, I made my database, made an account and made it data reader and data writer.

I have a problem inserting data into a table on a MySQL database using a VB.NET application. I have a simple form where when I set some data to the textboxes and I press a GO button, the code should execute a function called InsertCar() that takes all these values and insert them into the database and then return true if the transaction is done successfully or false otherwise. My problem is that nothing is being inserted into the table.
