/* *********************************************************** Stored procedure: tar_GetBooksBySearchWords Created: 2008-10-17 Author: Leszek Description: Retrieves books from the catalog taking into account page number. Books are ordered by publishing date (descending) and by title (ascending). Assumptions: Search words are separated by a single space. Input: @SearchWords - a list of search words separated by a single space (all words: max. 1000 chars, single word: max. 50 chars) @Separator - a search word list delimiter @PageSize - the number of items on a page (between 1 and 100) @PageNo - the current page number (must be greater than 0) @ShowNotReleased - determines if the books not yet released should be shown @SortOrder: Remarks: Sort orders greater than 100 are available only for Admins. 1 - Publication date [new to old] (the default sorting order) PubDate DESC 2 - Popularity [rating * number of ratings] [high to low] (compare to the Amazon’s Bestselling order) Rating*NumRatings DESC, PubDate DESC 3 - Rating [high to low], NumRatings [high to low], PubDate [new to old] Rating DESC, NumRatings DESC, PubDate DESC 4 - Rating [low to high], NumRatings [high to low], PubDate [new to old] Rating ASC, NumRatings DESC, PubDate DESC 5 - Price [high to low], PubDate [new to old] Price DESC, PubDate DESC 6 - Price [low to high], PubDate [new to old] Price ASC, PubDate DESC 100 - Date added [new to old] DateAdded DESC 101 - Date added [old to new] DateAdded ASC Output: @TotalItems - number of all books on all pages Example: - @SortOrder=3 represents sorting by Rating DESC, NumRatings DESC, PubDate DESC. - REPLICATE pads the numerical fields with 0s - All columns must be textual in order to concatenate them. ORDER BY CASE WHEN @SortOrder=3 THEN REPLICATE('0', 5-LEN(CONVERT(VARCHAR(5), Rating))) + (CONVERT(VARCHAR(5), Rating)) + REPLICATE('0', 5-LEN(CONVERT(VARCHAR(5), NumRatings))) + (CONVERT(VARCHAR(5), NumRatings)) + CONVERT(CHAR(30), PubDate, 121) END DESC, Remarks: "Filters imposed by sorting order" filter out books with no user rating (when the sorting order involves user ratings) and books with no price i.e. books available from sellers other than Amazon (when the sorting order involves the book price). ************************************************************** */ IF OBJECT_ID('tar_GetBooksBySearchWords', 'P') IS NOT NULL DROP PROC tar_GetBooksBySearchWords GO CREATE PROC tar_GetBooksBySearchWords @SearchWords NVARCHAR(1000), @PageSize INT, @PageNo INT, @ShowNotReleased BIT, @SortOrder TINYINT, @BookStatus INT = NULL, @TotalItems INT OUTPUT AS BEGIN SET NOCOUNT ON DECLARE @SearchWordTable TABLE (Word NVARCHAR(50)) INSERT INTO @SearchWordTable SELECT * FROM tar_SplitString(@SearchWords, ' ') DECLARE @StartRow INT, @EndRow INT SET @StartRow = (@PageNo-1) * @PageSize + 1 SET @EndRow = (@PageNo-1) * @PageSize + @PageSize -- count the total number of records on all pages SELECT @TotalItems = COUNT(*) FROM (SELECT sw.BookId FROM SearchWord sw JOIN @SearchWordTable st ON st.Word=sw.Word JOIN Book bk ON sw.BookId=bk.BookId -- Implementation of a dynamic filter "Show Books Not Yet Released".
