Esta versión es para SqlServer anterior, para una versión más nueva, pruebe con la otra.
Esta técnica utiliza el procedimiento almacenado con una mejor estructura para recuperar datos de forma eficiente Las características principales son
- procedimiento almacenado
- Inyección estructura libre y fácilmente adaptable sql
- Ajax
funcional y Muy útil

PASO: 2 (procedimiento almacenado)

@user_srno int=null,
@catSrno int=null,
@name varchar(200)=null,

@option varchar(20) = null,
@orderColumn int =null,
@orderDir varchar(20)=null,
@start int =null,

as
BEGIN
if @option='GetAllAdminCategory'
begin
select IDENTITY(int,1,1) as SnoID, null as abc,specialDiscount, additionalDiscount, baseDiscount, name,cast(srno as varchar(20)) as srno
--this method is userful for all sql server version (it can be made better by using fetch)
into #tempCategory
from categoryStd where [status] not in(4,14) and categoryStd.name like '%'[email protected]+'%'
declare @to as int = @[email protected]
select * from #tempCategory where SnoID>@start and SnoID<[email protected]
order by
CASE WHEN @orderColumn = 1 AND @orderdir = 'desc' THEN #tempCategory.[name] END DESC,
CASE WHEN @orderColumn = 1 AND @orderdir = 'asc' THEN #tempCategory.[name] END ASC,
CASE WHEN @orderColumn = 2 AND @orderdir = 'desc' THEN #tempCategory.[name] END DESC,
CASE WHEN @orderColumn = 2 AND @orderdir = 'asc' THEN #tempCategory.[name] END ASC
select count(*) from #tempCategory
