Sequence curval

Sequence vs. identity

   In the Sybase, you can use 'select _at__at_identity' to get the identity value used without requiring the transaction. When using a sequence we can do

     'select sequence.curval from dual' (Does this require a transaction?, dual is a system table) to get the value used. Assume I have two processes;

    	Process 1			Process 2
	---------			---------
	insert record
					insert record
	select seq.curval from dual
					select seq.curval from dual

If the second record is inserted before the first process 'select'. What curval I will get from procees 1?
