The column or columns serving as the unique row identifier for a table are the primary key of the table 作為表的唯一行標識符的列是表的主鍵。
Identity columns are commonly used in conjunction with primary key constraints to serve as the unique row identifier for the table 標識列通常與primary key約束一起用作表的唯一行標識符。

The fundamental rule of database design theory is that each table should have a unique row identifier , a column or set of columns used to distinguish any single record from every other record in the table 數(shù)據庫設計理論的基本原理是:每個表都應有一個唯一的行標識符,可以使用列或列集將任何單個記錄同表中的所有其他記錄區(qū)別開來。
