oracle/sql Creating a sequence without triggering -


I created a sequence with the beginning value as 2.

start sequence seq_ben with 2 increments by nocache noxile 1;

When I asked to show the next two numbers of that sequence 

  select seq_ben.nextval from double

And after running this code twice to give the next two values, I was asked to show the next sequence without triggering to move the next number and to add new rows in the above sequence Use the next three values. Is this possible? How can this generate a next sequence without triggering?

If you have provided a reference, you can use at least in the current session Once NXTVL .

However, I believe that if you really want to know the next number in order, then something fundamentally wrong about your design. Sequences are such designs as NexusVil is a nuclear operation, and two sessions can get the same number. Or in other words, the growing unique identifier is the guarantee that gives you. With this design, asking for the next potential value of the sequence is almost nonsensical.

You can try to use MAX () , which is often used as a poor man's solution for sequences.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
