Efficiently Paging Through Large Amounts of Data (PageIndex, Page Size) -SQL Server

In this article you learn how to fetch data according PageIndex and PageSize. In web application, it is much more important to increase webform performance, loadbalance.

In my development experience, some of table hold large amount of records (more than 2GB) and user need to shows records in GridView. But problem is when we select all records and loads in webforms, webform has crashed.

In that case, I will simply solved with Table Variable and using Grid Page Number and Page Size.

1. Create Procedure

CREATE PROCEDURE Load_Data_WithPaging    
      @PageIndex AS INT, /*Selected Row Index of selected grid*/
      @PageSize AS INT, /*Total page size of selected grid*/
      @TotalRecords AS INT OUT      /*used for display virtual page no*/
AS
BEGIN
      SET NOCOUNT ON;
      DECLARE @FromIndex AS INT = 0, @ToIndex AS INT = 0;
      
      
  SET @FromIndex = (@PageIndex * @PageSize) + 1; /*First row no selection*/
  SET @ToIndex = ((@PageIndex * @PageSize) + @PageSize);/*Last row no selection*/
      SET @TotalRecords = 0;
     
      /*Temp Table */
      DECLARE @TempTrans TABLE
      (
            SerialNumber INT,
            Id INT,
            AgentId INT,
            EntryDate DATETIME,
            TransactionCode VARCHAR(50),
            CustomerId INT,
            FromCurrencyId INT,
            SendAmount DECIMAL(20, 4),
            ToCurrencyId INT 
      );
     
      INSERT INTO @TempTrans 
         
      SELECT row_number() over (order by MT.EntryDate DESC) AS SerialNumber
             , MT.Id, MT.AgentId, MT.EntryDate
             , MT.TransactionCode, MT.CustomerId
             , MT.FromCurrencyId, MT.SendAmount
             , MT.ToCurrencyId
       FROM dbo.Mtr_MoneyTransfer MT
       ORDER BY MT.Id DESC
           
      SELECT * FROM @TempTrans
            WHERE SerialNumber BETWEEN @FromIndex AND @ToIndex   
           
      SELECT @TotalRecords = COUNT(*) FROM @TempTrans
     
END;

DECLARE @TotalRecords AS INT
EXEC Load_Data_WithPaging 1, 10, @TotalRecords out
SELECT @TotalRecords
