mssql 2012 feature is Sequence objects

create sequence MySeq as int
start with 1  -- Start with value 1
increment by 1-- Increment with value 1
minvalue 0 -- Minimum value to start is zero
maxvalue 100 -- Maximum it can go to 100
no cycle -- Do not go above 100
cache 50 -- Increment 50 values in memory rather than incrementing from IO

SELECT NEXT VALUE FOR dbo.MySeq AS seq_no;

SELECT current_value FROM sys.sequences WHERE name = 'MySeq';
