Must've indeed. Try this:

My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.

Worthy of mention, if you do opt to add a Calendar table, either of the proposed FUNCTIONs will make short work of populating it.
Any way you choose to accept it,...

I'm not seeing the same results as you. Try this:
CREATE TABLE #Modules
(
ModuleIdint,
Captionvarchar(20),
SourceNamevarchar(20),
MenuLevelint,
ParentIdint
)
insert into #Modules
Select 1, 'Test 1', null, 1, 0
UNION Select 2, 'Test 2', 'Form2', 2, 1
UNION Select...

Dwain,Your solution is working fine with sample data, but when I applied it to large data giving wrong result.
Means provide the multiple parent row for the given child row.

Vijay - I think we can be a little more succinct and avoid any unnecessary temporary tables like this:
;WITH MyModules AS (
SELECT m.ModuleID, Caption, SourceName, MenuLevel,...

Another, albeit awkward but likely method to achieve this is to convert the column containing 6-8 to a computed column like this:
SELECT GradeRange='''' + GradeRange
When you paste that result into...

An alternative to a Calendar table, is to use a FUNCTION to generate the calendar.
Like the one Jeff Moden gifted me with here: http://www.sqlservercentral.com/Forums/Topic1320527-392-2.aspx#bm1322829

I guess now I'll need to check whether I'm using the right version of DelimitedSplit8K!

Apology accepted!
Still no joy on hitting the optimal solution though. It seems I'm short by one doublet and one triplet. My current results are:
1. 15 doublets (30 districts)
2....
