Many tables within the database require unique numbers to be generated for use as the Primary key within the table, or just as sequences for other purposes. In Oracle this is achieved by use of Oracle Sequences. In SQL Server, these fields are identity columns.

In the below table all min/max values are 1 and 999999999, and cycle by 1, except where stated otherwise

Oracle Sequence Name	min/max values	SQL Server Identity Column Name	Table	Used to...
