Call: execute pagination_basic 'userdetail', '*', ', 'id', '1', '5', '1', '1', '1', '1 ', '',''

The statement at the end is split as follows:

Select top column name per page from [Table name] where [sort field name] <-- 1 reverse output if the column is smaller than the minimum value of the previous page

(Select min ([sort field name]) from -- 2 get the minimum value of a specified column name and Output

(Select top (current page-1) * [sort field name] from [Table name] where [condition] [sort type]) per page-3 select the inverted output of the total number of pages

As Tmep_QC) -- 4 create a temporary table named Tmep_QC -- 2 get the minimum value in a specified column name and Output

And [condition] [sorting type] -- 1. If the inverted output column is smaller than the minimum value of the previous page number
