Okay so I need to find out if any of this is possible and the code needed.

I'm using MySQL and need to know how to create, delete, move entries, check if they exist, search / filter results with containing strings, link tables and updating results.
Any other functions would also be useful to me but the ones above are essential.

I'm using ADO.NET MySQL Connector in VB.NET.

Thank you for any help.

Everything is good, except one part: "I'm using MySQL". I think this is a huge exaggeration.

All of this is basic SQL, as far as I can tell. What do you mean 'the code needed' ? We can't write code based on these vague requests. Do you know SQL ?

Yeah sorry, I meant something like this for each:
Dim DatabaseConnection As New MySqlConnection("Server=;Database=antivuru_Rozzle;Uid=antivuru_Rozzle;Pwd=passwordexample")
Dim Query As String = String.Empty
Dim SQLCommand As MySqlCommand
Dim DataReader As MySqlDataReader

Query = "INSERT INTO users (Username,Password,Email_Address,Full_Name,Join_Date) " & _
"VALUES ('" + TextBox1.Text.ToLower + "','" + TextBox2.Text + "','" + TextBox3.Text + "','" + TextBox4.Text + "','" + Date.Today + "') "
SQLCommand = New MySqlCommand(Query, DatabaseConnection)

Well, that code is a disaster. you should read up on SQL injection attacks, and parameterised queries. Along the way, you'll see how to run any SQL you like.

Where can I read up on these?
