| 1. | Rid lock on a single row in a table identified by a row identifier
Rid =表中单个行的锁，由行标识符( rid )标识。 |
| 2. | The column or columns serving as the unique row identifier for a table are the primary key of the table
作为表的唯一行标识符的列是表的主键。 |
| 3. | Identity columns are commonly used in conjunction with primary key constraints to serve as the unique row identifier for the table
标识列通常与primary key约束一起用作表的唯一行标识符。 |
| 4. | Identity columns are typically used together with primary key constraints to serve as the unique row identifier for the table
标识列通常与primary key约束一起使用，作为表的唯一行标识符。 |
| 5. | Set if the column contains a persistent row identifier that cannot be written to , and has no meaningful value except to identity the row
如果列包含无法写入的不变的行标识符，并且除了标识行外没有其他有意义的值，则设置该值。 |
| 6. | Set if the column contains a persistent row identifier that cannot be written to , and has no meaningful value except to identify the row
如果列包含无法向其写入的持久性行标识符，并且除了标识行外没有其他有意义的值，则应设置该值。 |
| 7. | The provider sets dbcolumnflags isrowid if the column contains a persistent row identifier that cannot be written to , and has no meaningful value except to identity the row
如果列包含不能写入的持久性行标识符，并且该标识符除了标识行以外没有其他有意义的值，则提供程序设置dbcolumnflags _ isrowid 。 |
| 8. | 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
数据库设计理论的基本原理是：每个表都应有一个唯一的行标识符，可以使用列或列集将任何单个记录同表中的所有其他记录区别开来。 |
