For example, I can define one resource reference to a data source with a specific isolation level for a table, while defining another reference to the same database with a different isolation level. 例如对表格来说,能够使用特定的分离级别在数据源中定义一个资源应用,同时使用不同的分离级别在相同数据库中定义另一个引用。
REFERENCE, in turn, is a system type that is the data type of the object identifier column of any typed table. 反过来,REFERENCE是一个系统类型,它是任何类型化表的对象标识符的数据类型。
The reference include the directly quote or the reference historical data and table of contents. 参考文献包括直接引用或参考的史料及论著目录。
