An application requires multiple numbers to be assigned at the same time. For example, an application needs to reserve five sequential numbers. Requesting identity values could result in gaps in the series if other processes were simultaneously issued numbers. Callingsp_sequence_get_rangecan retrieve...

按照网上搜索的资料来看,踪标志272让SQL Server使用以前的代码来实现标识列的功能。 That flag sets SQL 2012 back to the prior code for IDENTITY fields. However, unless you are actually running out of numbers, there is no reason to use that flag. IDENTITY fields are unique, not sequential. You ...
Under the full recovery model or bulk-logged recovery model, conventional backups also include sequential transaction log backups (or log backups), which are required. Each log backup covers the portion of the transaction log that was active when the backup was created, and it includes all log...

您可以設定指定索引的選項 ALLOW_ROW_LOCKS、 ALLOW_PAGE_LOCKS、 OPTIMIZE_FOR_SEQUENTIAL_KEY、 IGNORE_DUP_KEY和STATISTICS_NORECOMPUTE ,而不需重建或重新組織該索引。 修改的值會立即套用在索引上。 若要檢視這些設定,請使用 sys.indexes。 如需詳細資訊,請參閱 設定索引選項。

It specifies the maximum number of blocks read in one I/O operation during a sequential scan. The total number of I/Os needed to perform a full table scan depends on such factors as the size of the table, the multiblock read count, and whether parallel execution is being utilized for ...
