3 Ways to paging SQL Server are as follows: ---SQL Server 2005-page statement collection ----Disadvantages: Top: Complex SQL must be written by the user and no composite primary key is supported Max: Users must write complex SQL and do not support non-unique column sorting --row: sqlserver2000 not supported -------------------------------- Id,email,qq,wech

value is greater than the record of the maximum ID value for the first 40 records.This query has one condition, that is, the ID must be of type int.The third method:Select Top Ten * from ( Selectover (order by as RowNumber,* from test) Awhere>Principle: First sort all the data in the table according to a rownumber, then query rownuber more than 40 of the first 10 recordsThis approach is similar to a paging method in Oracle, but only supports ver

In SQL Server database operations, we often use stored procedures to implement the query data paging to facilitate the browsing of the viewer.

is, they have to take out of the database No. 0 to 1010th of the data so that the query out of the number of records, but the amount of data transmission network is very large! Therefore, a better paging approach should be: Retrieve data from a block of page size only from the database each time you page. In this way, although each page will need to query the database, but the number of records to query out a small amount of data transmission n

Killergo's Column 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 of 15,000 data, and the former is obviously better than the latter in the case of 20000-30000 data. The larger amount of data has not been tested. Note that there are key
