How to connect 2 MSSQL queriues with c#? - sql-server-2005

Question

I have following question - I need to build category list from unique department name and under each department list articles, which belongs to it.
I wrote 2 mssql queries:
1) Selecting unique department's name (table consists of id and string name):
select distinct (fs.ob_no), fs.c_name as fs_c_name from et_filials_suggest fs order by fs.ob_no
and getting something like this:
ob_no fs_c_name
244400 IT Department
244401 HR Department
2) Than I select articles:
select s.ob_no as s_ob_no,
s.c_name as s_c_name,
s.e_fio,
s.e_text_header,
s.e_datetime,
s.e_link_filial,
fs.c_name
from et_suggest s
inner join et_filials_suggest fs on fs.ob_no = s.e_link_filial
where s.c_visible=1
AND s.e_lean_flag=1
AND fs.c_visible=1
and getting something like this:
s.ob_no | s.c_name | s.e_fio | s.e_text_header | s.e_datetime |s.e_link_filial | fs.c_name
458713 | Article_sys_name | Me |Aricle_vis_name | 2013-11-12 00:00:00.000 |44410 | IT deparment
And here goes the problem, I don't understand how to make list, e.g.:
IT Department
Article 1
Article 2
HR Department
Article 3
....
Here I get list of departments:
<%#DataBinder.Eval(Container.DataItem, "fs_c_name")%>
But how can I connect it with articles? Seems to me that I should set variable in first query but how can I use it later?
Here is the full example of code I've made - article is limited to 1 and it displays under each department without connection to it:
<mso:Query ID="Query1" runat="server" CommandType="Text" CommandText="select distinct (fs.ob_no), fs.c_name as fs_c_name from et_filials_suggest fs order by fs.ob_no">
<ItemTemplate>
<b><%#DataBinder.Eval(Container.DataItem, "fs_c_name")%></b><br />
<mso:Query ID="Query1" runat="server" CommandType="Text" CommandText="
select top (1)
s.ob_no as s_ob_no,
s.c_name as s_c_name,
s.e_fio,
s.e_text_header,
s.e_datetime,
s.e_link_filial,
fs.c_name
from et_suggest s
inner join et_filials_suggest fs on fs.ob_no = s.e_link_filial
where s.c_visible=1
AND s.e_lean_flag=1
AND fs.c_visible=1">
<ItemTemplate>
<%#DataBinder.Eval(Container.DataItem, "s_c_name")%><br />
</ItemTemplate>
</mso:Query>
</ItemTemplate>
</mso:Query>
Thanks in advance for any kind of help.
UPDATE:
Well i have an idea - if i change in 2nd query inner join to left join and add where clause i can get list of articles for department:
select
s.ob_no as s_ob_no,
s.c_name as s_c_name,
s.e_fio,
s.e_text_header,
s.e_datetime,
s.e_link_filial,
fs.c_name
from et_suggest s
left join et_filials_suggest fs on fs.ob_no = s.e_link_filial
where s.c_visible=1
AND s.e_lean_flag=1
AND fs.c_visible=1
AND s.e_link_filial=244411
But i still don't know how to change number from:
AND s.e_link_filial=244411
to variable from the first query:
select distinct (fs.ob_no), fs.c_name as fs_c_name from et_filials_suggest fs order by fs.ob_no

Answer 1

Remove the line
AND s.e_link_filial=244411
and all records will be returned
you should instead add the following line
ORDER BY s.e_link_filial=244411
By the way, in web page development, while binding grid view with this type of information, I use a different approach.
Let me know if you are interested to know, I will update my answer.
