There was a situation where I had to implement fast/effective Paging, Sorting and Filtering with Stored Procedure in MS SQL Server. There are a number of articles and blogs where you can find about to do Paging, Sorting and Filtering with Stored Procedure in MS SQL Server. Hence, I started and done some research on this to find out the best solution. I found it in “Pagination with OFFSET / FETCH : A better way”

Using OFFSET / FETCH into the CTE I have created a stored procedure that was at least faster twice in return time as the alternatives found on the internet.

Here, I have kept all the implementation details along with a complete example.

Prerequisites
You should have a basic knowledge of MS SQL Stored Procedure, queries and CTE.

How to do effective Paging, Sorting and Filtering with Stored Procedure

To implement and execute this let us follow three steps:

  • Create table.
  • Insert data into the table.
  • Create stored procedure.


Create table
CREATE TABLE Employee 

    Id INT NOT NULL IDENTITY(1,1) PRIMARY KEY, 
    Name varchar(25) NOT NULL, 
    City varchar(25) NOT NULL 


Insert data into the table
declare @i int = 1 
declare @total int = 500000 
 
while @i <= @total 
begin 
    insert into Employee2 (Name, City) values (RIGHT('000000'+convert(varchar, @i),6), convert(varchar, @i%4)) 
    set @i += 1; 
end

For testing purpose, I have added 5 lakh records into the Employee table.

Create stored procedure
--GetAllEmployeesWay4 '', '', 1, 25, 'Name', 'Asc' 
--GetAllEmployeesWay4 'Name', '1', 1, 25, 'Name', 'Asc' 
--GetAllEmployeesWay4 'City', '1', 1, 25, 'Name', 'Asc' 
CREATE PROCEDURE [dbo].[GetAllEmployeesWay4] 

    @SearchColumn NVARCHAR(50) = NULL, 
    @SearchValue NVARCHAR(50) = NULL, 
    @PageNo INT = 1, 
    @PageSize INT = 10, 
    @SortColumn NVARCHAR(20) = 'Name', 
    @SortOrder NVARCHAR(20) = 'ASC' 

AS BEGIN 
    SET NOCOUNT ON; 
 
    SET @SearchColumn = LTRIM(RTRIM(@SearchColumn)) 
    SET @SearchValue = LTRIM(RTRIM(@SearchValue)) 
 
    ; WITH CTE_Results AS  
    ( 
        SELECT Id, Name, City from Employee 
 
        WHERE @SearchColumn= '' OR  (  
                CASE @SearchColumn  
                    WHEN 'Name' THEN Name  
                    WHEN 'City' THEN City 
                END 
            ) LIKE '%' + @SearchValue + '%' 
 
            ORDER BY 
            CASE WHEN (@SortColumn = 'Name' AND @SortOrder='ASC') 
                        THEN Name 
            END ASC, 
            CASE WHEN (@SortColumn = 'Name' AND @SortOrder='DESC') 
                        THEN Name 
            END DESC, 
            CASE WHEN (@SortColumn = 'City' AND @SortOrder='ASC') 
                        THEN City 
            END ASC, 
            CASE WHEN (@SortColumn = 'City' AND @SortOrder='DESC') 
                        THEN City 
            END DESC  
            OFFSET @PageSize * (@PageNo - 1) ROWS 
            FETCH NEXT @PageSize ROWS ONLY 
    ), 
    CTE_TotalRows AS  
    ( 
        select count(ID) as TotalRows from Employee 
        WHERE @SearchColumn= '' OR  (  
                CASE @SearchColumn  
                    WHEN 'Name' THEN Name  
                    WHEN 'City' THEN City 
                END 
            ) LIKE '%' + @SearchValue + '%' 
    ) 
    Select TotalRows, t.Id, t.Name, t.City from dbo.Employee as t, CTE_TotalRows  
    WHERE EXISTS (SELECT 1 FROM CTE_Results WHERE CTE_Results.ID = t.ID) 
 
    OPTION (RECOMPILE) 
END


Execute stored procedure
Execute the above stored procedure with different parameters and you can get result accordingly:
GetAllEmployeesWay4 '', '', 1, 25, 'Name', 'Asc'
GetAllEmployeesWay4 'Name', '1', 1, 25, 'Name', 'Asc'
GetAllEmployeesWay4 'City', '1', 1, 25, 'Name', 'Asc'


Complete example

For your reference, I have kept complete example in a single folder and uploaded that with this article and it contains below script files:
Step1_Create_Table
Step2_Insert_Data_into_Table
Step3_Create_Stored_Procedure

Summary
Now, I believe you will be able to do Effective Paging, Sorting and Filtering with Stored Procedure in MS SQL Server using.
