For a heap , a row locator is a pointer to the row 對于堆,行定位器是指向行的指針。
For a clustered table , the row locator is the clustered index key 對于聚集表,行定位器是聚集索引鍵。
The pointer from an index row in a nonclustered index to a data row is called a row locator 從非聚集索引中的索引行指向數(shù)據(jù)行的指針稱為行定位器。
The structure of the row locator depends on whether the data pages are stored in a heap or a clustered table 行定位器的結(jié)構(gòu)取決于數(shù)據(jù)頁是存儲在堆中還是聚集表中。
