1. Create Stored Proc in Database for read Table for Page :
CREATE PROCEDURE dbo.GetListPatientsbyPage
@LimitC INT,
@PageC int,
@TotalC int output
AS
BEGIN
SELECT Birthday, UID, Surname,Name,MiddleName
,rowNum, (rowNum / @LimitC) + 1 as pageNum
FROM (
SELECT a.Birthday,UID, Surname,Name,MiddleName
, Row_Number() OVER (order by surname) as rowNum
FROM regPatients a
) x
WHERE (rowNum / @LimitC) + 1 = @pageC
set @TotalC=(Select count(*) FROM regPatients a with (nolock))
END
where 3 parameter:
@LimitC - Row Per Page
@PageC - number Page
@TotalC - count all rows in request
2.
