sql 具有偏移和限制的MS SQL分页1

Posted 2021-05-13

-- Offset starting from 1.
-- This kind of paging returns one extra row 
-- such that in mobile apps, 
-- we can automatically handle the scroll event 
-- in cases where the record contains extra rows

-- For example: If we asked for 10 records and 
-- the script returns 11, We can write code to fetch 
-- the next 10 records if the last returned list
-- has one extra data.

-- Note : We always need to hide the extra rows that 
-- the script returns. 
-- Example : If the script returns 11 when 10 was asked, 
-- hide the last 11th record.

-- That last row is applicable to trigger the next fetch 
-- when the user reaches the end of the page
-- and needs to scroll further
