    stmt.SQL = "INSERT INTO Users (Username, Password, Role) VALUES (?, ?, ?)"

    stmt.AddParameter(username)

    stmt.AddParameter(password)

    stmt.AddParameter(role)

    If db.ExecuteStatement(stmt) Then

        Return True

    Else

        Return False

    End If

End Function

用户登录 Function LoginUser(username As String, password As String) As Boolean Dim db As New Database Dim stmt As New SQLStatement stmt.SQL = "SELECT FROM Users WHERE Username = ?
