The limited mode runs the fastest, and the number of scanned pages is the least. For an index, only

"Which of the following is more efficient for SQL Server insert operations in heap tables or clustered index tables? Why is it high ?" Some colleagues have asked me this question before. To ensure the record efficiency of the logstore, I did a simple test. I should first emphasize the following concepts: Heap table:For a table without clustered indexes, the iam page and PFS page are used to determine which page has free space. Clustered index

Pages in the hybrid zone can be allocated to multiple database objects. pages in the unified zone must be allocated to a database object.4. when applying for a space for a database object, SQL Server needs to use the GAM, SGAM, PFS system page information. After the space is allocated, it also maintains GAM, SGAM, information on the

The automatic increase in the space of the tempdb database should be allowed. If it is set to not allow automatic growth, when the query operation creates a temporary table that exceeds the tempdb database capacity, the operation cannot be completed. Appropriately set the growth margin of the tempdb database. A small growth margin will generate more external fr

SQL Server 2000 uses IAM pages to browse through the heap. The data pages and rows within a heap are not in any particular order, and are not linked together. The only logical connection between data pages is a connection that is recorded within an IAM page. For an insert operation, when SQL Server 2000 needs to insert a new row and the cu

short, if it appears, note: 1, SQL Server does not have significant memory and disk bottlenecks. 2, the application issued a large number of concurrent statements to modify the same table, and the modification operation is concentrated on the same page, or a few pages, a hot page. 3, this bottleneck can not be solved by improving the hardware configuration, only modify the table storage, so that the changes scattered on more page, improve the ability of concurrent modification.How to mitigate H
