Hello, i'm trying to make my program change a value in a database.
I've got a database called Account, and a Table called Accounts. I have 4 columns in this table. Id(Key column), UserName, Password and Adminpower.
What I am trying to do is to make a button change a value in that table. What I do not know is how to make the program know which row i want to change the value in.
Private Sub btnAdmin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdmin.Click
Dim cmd As SqlCommand
Dim reader As SqlDataReader
con = New SqlConnection(_connectionString)
cmd = con.CreateCommand()
cmd.CommandText = "ALTER Accounts ('Adminpower') VALUES('1')"
reader = cmd.ExecuteReader()
If Not reader.HasRows Then
MessageBox.Show("Something is wrong.")
That's the code so far for the button. So what I want it to do is to change the Adminpower column from 0 to 1 when pressing that button. Yes I have already connected it to the database.
When I try to press the button I get an error saying that the table doesn't exist.
Any help is appreciated.
Problem solved. I got it working, I'll keep all the text here if anyone else has a similar problem. And this is what I used:
UPDATE Accounts SET Adminpower = 1 WHERE '" & TextBox1.Text & "' = ""UserName"" AND '" & TextBox2.Text & "' = ""Password"""
