주의
SQL Server allows the row identity property on a single column within a table. Identity, like a primary key, identifies a row uniquely. SQL Server implements row identification using a numeric value. As rows are inserted, SQL Server generates the row value for an identity column by adding an increment to the existing maximum value.
For example, the identity values for the first three rows inserted into a table containing a column defined with identity, an identity seed of 1, and an increment value of 3, are 1, 4, and 7.
