Simple Pivot Question

have a query (select  [AcctNo], [shares], [symbol] from MyTable) that returns:

[AcctNo], [shares], [symbol]
acct01,    100 ,  msft
acct02,    150,  msft
acct02,    200,  aapl
acct02,    250 ,  aapl
acct03,    300 ,  intl
.
..

I'd like to pivot the data so it displays as:
[ ] ,    [acct01] , [acct02], [acct03], .....
msft,        100,         150,      0
aapl,             0,         450,     0
intl ,              0,             0,     300
.
..
Number of [AcctNo] and [symbol] are undetermined.

Any help on the SQL here would be appreciated.

try this
DECLARE @accounts VARCHAR(max)
;with accounts as (Select distinct AcctNo From MyTable)
Select @accounts = COALESCE( '[' + AcctNo + '],' + @accounts,'[' + AcctNo + ']') from accounts 

Exec('Select symbol,' + @accounts + ' From  MyTable PIVOT (Sum(shares) for AcctNo in (' + @accounts + ')) as PVT ')
