Stored procedure to achieve paging, sorting and filtering in SQL Server 2008 is given below.
CREATE PROCEDURE [dbo].[uspTableNameOperationName] @Query NVARCHAR(50) = NULL,
@Offset INT = 0,
@PageSize INT = 10,
@Sorting NVARCHAR(20) = 'ID DESC',
@TotalCount INT OUTPUT
AS
BEGIN
SET NOCOUNT ON;
SET @Query = LTRIM(RTRIM(@Query));
SELECT @TotalCount = COUNT([Id])
FROM [dbo].[TableName]
WHERE IsDeleted = 0
AND (@Query IS NULL
OR [ColumnOne] LIKE '%' + @Query + '%'
OR [ColumnTwo] LIKE '%' + @Query + '%');
WITH CTEResults
AS (SELECT Id,
[ColumnOne],
[ColumnTwo],
[ColumnThree],
ROW_NUMBER() OVER(
ORDER BY CASE
WHEN(@Sorting = 'ID DESC')
THEN [Id]
END DESC,
CASE
WHEN(@Sorting = 'ID ASC')
THEN [Id]
END ASC,
CASE
WHEN(@Sorting = 'COLUMNONE ASC')
THEN [ColumnOne]
END ASC,
CASE
WHEN(@Sorting = 'COLUMNONE DESC')
THEN [ColumnOne]
END DESC,
CASE
WHEN(@Sorting = 'COLUMNTWO ASC')
THEN [ColumnTwo]
END ASC,
CASE
WHEN(@Sorting = 'COLUMNTWO DESC')
THEN [ColumnTwo]
END DESC) AS RowNum
FROM [dbo].[TableName]
WHERE IsDeleted = 0
AND (@Query IS NULL
OR [ColumnOne] LIKE '%' + @Query + '%'
OR [ColumnTwo] LIKE '%' + @Query + '%');
SELECT *
FROM CTEResults
WHERE RowNum BETWEEN @Offset + 1 AND(@Offset + @PageSize);
END;
GOIn the above query, we are using CASE to do the conditional sorting. And with help of a common table expression (CTE), we do the paging. For filtering (here only string comparison), we are using LIKE.
If you are using SQL Server 2012 or later, then you have other options to do paging like by using OFFSET FETCH.
Story in short
During this post is written, I was working on an Angular 6 + ASP.NET Core 2.1 web app. The DB provided was a SQL Server 2008. Used Dapper to do the repository level coding.
