  PageNumber pages from the client  
 totalrecouds The total number of records in the table select COUNT (*) from table name  
 totalpages Total pages  
 totalpages=totalrecouds%pagesize==0?totalrecouds/pagesize:totalrecouds/pagesize+1 
  Pages calculates the previous pages data  
 pages= pagesize* (pageNumber-1)  
 sql statement:  
 select Top PageSize * FROM table name where id  not in (select top pages ID from table name ORDER by ID) Order by id 
  Second pagination method
& Nbsp;pagesize How many data   are displayed per page;
 pagenumber pages from client
 pages=pagesize* (pageNumber-1) +1
  Select Top PageSize * from table name where id>= (select Max (ID) from (select top pages ID from table name ORDER BY ID ASC) T)

MySQL paging  
  Required parameters:  
 pagesize shows how many data   per page;
 pagenumber pages   from the client;
Total number of records in  totalrecouds table select COUNT (*) from table name  
 totalpages total pages  
 totalpages= totalrecouds%pagesize==0?totalrecouds/pagesize:totalrecouds/pagesize+1 
 pages start position  
 pages= pagesize* (pageNumber-1)  
 sql statement:  
 select * from table name limit pages, pageSize;  
 mysql paging depends on the keyword limit it requires two parameters: start position and pagesize 
  Start position = page Size * (pages 1)  
  Start position = pagesize* (pageNumber-1)

Oracle Paging
PageSize How many data are displayed per page
PageNumber pages coming from the client
Total number of records in the Totalrecouds table select COUNT (*) from table name
TotalPages Total Pages
Totalpages=totalrecouds%pagesize==0?totalrecouds/pagesize:totalrecouds/pagesize+1
StartPage Start position
Startpage= pagesize* (pageNumber-1) +1
Endpage=startpage+pagesize
SQL statements
Select A.* from
(
Select RowNum num, t.* from table name t where column = some value order by ID ASC
) A
where A.num>=startpage and A.num<endpage

DB2 Sub-page
int startpage=1//Start Page
int endpage; End Page
int pagesize=5; Page size
int pagenumber=1//Request page

Startpage= (pageNumber-1) *pagesize+1
Endpage= (startpage+pagesize);


SQL statements
SELECT * FROM (select field 1, Field 2, Field 3, Field 4, Field 5,rownumber () over (Order by sort field ASC) as rowID from table name) as a where A.rowid >= StartPage and A.rowid <endpage
