You need a dynamic cross tab query , If Pagecategory are finite and
constant , you can do some thing like this
Select b.docname,
MAX(case when PageCategoryID = 1 then c.pagecategory end ) as
Pagecategory01,
MAX(case when PageCategoryID = 2 then c.pagecategory end ) as
Pagecategory02,
MAX(case when PageCategoryID = 3 then c.pagecategory end ) as
Pagecategory03,
MAX(case when PageCategoryID = 4 then c.pagecategory end ) as
Pagecategory04
FROM
(select distinct docid,pagecategoryid from XREF_Doc_Page) a
inner join documents b where a.docid = b.docid
inner join pagecatefory c where a.pagecategoryid = c.pagecategoryid
group by b.docname
order by b.docname
