ReCursive/While Loop - sql

Question

I am trying to build a view that looks at a table that has three columns; Building, Lane, Lot. I need to be able to loop through the table dynamically to display the Building, Lane and Lot all on one row.
Sample:
>Building Lane Lot
> 1 1001 56789
> 1 1002 12489
> 1 1002 37159
> 1 1002 71648
> 3 3001 27489
> 3 3001 67154
> 3 3002 47135
> 3 3003 84271
> 3 3003 96472
> 3 3003 94276
Results
> Building Lane Lots
> 1 1001 56789
> 1 1002 12489, 37159, 71648
> 3 3001 27489, 67154
> 3 3002 47135
> 3 3003 84271, 96472, 94276
I tried a recursion union but received a message that I had exceded the max amount of 100.
I also tried a loop but it just kept going and did not concantenate as I had hoped.
So far in the table there are over 300 lot numbers for one building in one lane with the potential of huders more.

It looks like you're looking for something similar to the below script (see this SQL Fiddle example):
DECLARE #row TABLE (
A VARCHAR(1),
AA VARCHAR(1),
B VARCHAR(4)
)
INSERT INTO #row VALUES(1,1,1001)
INSERT INTO #row VALUES(1,1,1002)
INSERT INTO #row VALUES(1,1,1003)
INSERT INTO #row VALUES(1,2,1001)
INSERT INTO #row VALUES(2,1,1001)
INSERT INTO #row VALUES(2,1,1002)
INSERT INTO #row VALUES(2,1,1003)
INSERT INTO #row VALUES(2,1,1004)
INSERT INTO #row VALUES(2,1,1005)
INSERT INTO #row VALUES(2,2,1001)
INSERT INTO #row VALUES(2,2,1002)
INSERT INTO #row VALUES(3,1,1001)
SELECT *
FROM #row
SELECT r1.A
, r1.AA
, STUFF((SELECT ', ' + r2.B AS [text()]
FROM #row r2
WHERE r1.A = r2.A AND r1.AA = r2.AA
ORDER BY r2.B
FOR XML PATH('')),1,1,'') AS "Row"
FROM #row r1
GROUP BY A, AA
So for your query, it will look something like this:
SELECT r1.Building
, r1.Lane
, STUFF((SELECT ', ' + r2.Lot AS [text()]
FROM YourTable r2
WHERE r1.Building = r2.Building AND r1.Lane = r2.Lane
ORDER BY r2.Lot
FOR XML PATH('')),1,1,'') AS "Row"
FROM YourTable r1
GROUP BY Building, Lane
