You're just missing few single quotes
make it like below and it will work
set
@strSQL = 'SELECT a.Id,dbo.GetCategoryName(a.Category) as Category,dbo.GetSubCategoryName(a.SubCategory) as SubCategory,dbo.GetSubSubCategoryName(a.SubSubCategory) as SubSubCategory,a.Product,a.Description,a.Thumbnail,a.Image1,a.Image2,a.Image3,a.Image4,a.Image5,a.Image6,a.Image7,a.Image8,a.Publish,a.New from tbl_product a inner join tbl_category b on a.Category=b.id inner join tbl_subcategory c on a.SubCategory=c.id inner join tbl_sub_subcategory d on a.SubSubCategory=d.id WHERE a.Publish = 1 and b.CategoryName like ''%'' + @Category1 + ''%'' and c.SubCategoryName like ''%'' + @SubCategory1 + ''%'' and d.SubSubCategory like ''%'' + @SubSubCategory1 + ''%'' ORDER BY ' + @Sort + ' ' + @SortDirection
