Sequence feature which has been in Oracle for a number of years is now available in MS SQL 2012! A Sequence object is an object that provides functionality similar to Identity (Autonumber) column. The sequence object can be used with more than one table which is not possible in identity object. This is useful when you have parent-child tables and you want to know the value of the ID column before you insert records. We are including some examples here that you can use with SQL Server 2012.
