Question

I want to sorting my ArticleID down to up(DESC). How can i edit this code to do that?
thank you so much

ORDER  BY CASE 
        WHEN @order = 'AddArticleType.ArticleID' THEN CONVERT(nvarchar,AddArticleType.ArticleID) 
        WHEN @order = 'Title' THEN CONVERT(nvarchar, Title) 
        WHEN @order = 'family' THEN CONVERT(nvarchar, family)
        WHEN @order = 'AddArticleType.ArticleType' THEN 
         CONVERT(nvarchar, AddArticleType.ArticleType ) 
      END

Going back to @Gordon’s good answer from your previous post, this should work:

ORDER  BY 
   CASE WHEN @order = 'AddArticleType.ArticleID' THEN AddArticleType.ArticleID END DESC,
   CASE WHEN @order = 'Title' THEN Title END,
   CASE WHEN @order = 'family' THEN family END,
   CASE WHEN @order = 'AddArticleType.ArticleType' THEN AddArticleType.ArticleType END

I’ve simplified your code for testing:

Good luck.
