A stored procedure is a compiled, optimized set of SQL statements placed on the database server, which can be called directly by the application. There are several advantages to using stored procedures:1. Faster execution speed than normal SQL statements2, easy to centralized control3, can reduce the network traffic4,

Paging of database data on the UI is a common issue. It is easy to find various "General stored procedure" codes on the Internet, and some custom query conditions make it easy to use. I plan to use this article to briefly discuss the paging stored procedures based on SQL server 2000 and the evolution of paging stored procedur

Recently, because of a bit of free time, I thought about how to use the paging of stored procedures on the SQL Server platform, now listed below.
In the actual test, the performance of the two is roughly equal in the case
Question:
Data is frequently queried in applications. When the data size of the query results is large, it takes a lot of time to retrieve the results and display the interface. To avoid this problem, only part of the data should be retrieved at a time, that is, the common paging method should be used for processing. The paging problem seems very simple in Asp.net. You only need to enable paging in the gridview. After pagination is enabled, the gridview associated data source control still loads
