Need tool/utility to get list of tables from sql query

Question

Hi,
I often have to analyze huge queries without having access to database. Is there any tool where I can submit the a sql query and it gives me list of tables used in the query.  I also need similar thing for documentation.
Let me know if anybody uses anything like this.
Thanks.

You can find the size of each table, and thus list the tables in the process.
SET NOCOUNT ON
DBCC UPDATEUSAGE(0)
-- DB size.
EXEC sp_spaceused
-- Table row counts and sizes.
CREATE TABLE #t
[name] NVARCHAR(128),
[rows] CHAR(11),
reserved VARCHAR(18),
data VARCHAR(18),
index_size VARCHAR(18),
unused VARCHAR(18)
INSERT #t EXEC sp_msForEachTable 'EXEC sp_spaceused ''?'''
SELECT *
FROM #t
-- # of rows.
SELECT SUM(CAST([rows] AS int)) AS [rows]
FROM #t
SELECT
t.NAME AS TableName,
p.rows AS RowCounts,
SUM(a.total_pages) * 8 AS TotalSpaceKB,
SUM(a.used_pages) * 8 AS UsedSpaceKB,
(SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM
sys.tables t
INNER JOIN
sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN
sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN
sys.allocation_units a ON p.partition_id = a.container_id
WHERE
t.NAME NOT LIKE 'dt%'
AND t.is_ms_shipped = 0
AND i.OBJECT_ID > 255
GROUP BY
t.Name, p.Rows
ORDER BY
t.Name
--- SQL2005
select o.name
, reservedpages = sum(a.total_pages)
, usedpages = sum(a.used_pages)
, pages = sum(case when a.type <> 1 then a.used_pages
when p.index_id < 2 then a.data_pages else 0 end)
, SUM(a.used_pages)*8096 AS 'Size(B)'
, rows = sum(case when (p.index_id < 2) and (a.type = 1) then p.rows else 0 end)
from sys.objects o
join sys.partitions p on p.object_id = o.object_id
join sys.allocation_units a on p.partition_id = a.container_id
where o.type = 'U'
group by o.name
order by 3 desc --biggest tables first
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.
