The stored procedure above set nocount off uses the latest SQL SERVER Technology-table variables. It should be said that this stored procedure is also a very good paging
SQL Server compact does not support top and row_number. the frequently used SQL pages cannot be used in SQL Server compact. How does SQL Server compact implement paging?
The answer is order by, offset, and fetch. However, SQL Server compact4.0 and later are required.
With t
fariqi descselect O. GID, O. mid, O. title, O. fadanwei, O. fariqi from tgongwen o, @ indextable twhere O. gid = T. NID and T. id> @ pagelowerboundand T. ID
The above stored procedures use the latest SQL server technology-Table variables. It should be said that this stored procedure is also a very good paging stored procedure. Of course, in this process, you can also write the table variables as temporary
----------------------------------------Why is that? Because subqueries are done on the index, and ordinary queries are done on a data file, the index file is generally much smaller than the data file, so it is more efficient to operate.You can actually use a similar strategy mode to deal with paging, such as judging if it is within 100 pages, using the most basic paging method, more than 100 pages, then us
hours, several 1100 or similar, the efficiency performance is not too obvious. However, if you imagine this by using the default paging method to display tens of millions and even hundreds of thousands of of books, it is not OK.
The way to replace the default paging is to customize pagination, and the job you have to do is to use code to judge and get the right paging

Database paging is a commonplace issue. If you use the ORM Framework and then use LINQ, a skip and take can be done. However, sometimes due to limitations, you need to use stored procedures to implement them. There are already many ways to implement paging using stored procedures in SQL Server. Before the interview encountered this problem, asked how to efficient
