      'Declaring variables
     Dim conn As New MySqlConnection()
  Dim sqlCmd As MySqlCommand 
  'Connection string to MySQL
        conn.ConnectionString = "Persist Security Info=False;database=springboot;server=localhost;Connect Timeout=30;user id=springboot; pwd=springboot"
        Try
      'Connecting and executing the query
            conn.Open()
   sqlCmd = New MySqlCommand( query, conn)
   sqlCmd.ExecuteNonQuery()
   'Closing the query
   conn.Close()
        Catch myerror As MySqlException
  'Throwing exceptions
            Console.WriteLine("Error connecting to database!")
            Exit Sub
