Merge or Union Multiple Tables to one big table

Question

Hi All,
I am new to SQL and learning great. I have a use to merge multiple tables. Every table has different kind of data but BP ID is same in every table (but some table have more BP IDs and some are less). The below is sample…
Table A
BPID -  Cost – Profit
0001 – 10 -4
0002 -11 - 3
Table B
BPID - Name – Address
0003 – John - Dallas
0002 –Mark - Huston
Table C
BPID – Zip code – State
0004- 74001 – TX
0002-75008 – TX
Output (after merging in Table A+B+C) would be like this…
BPID – Cost – Profit – Name – Address- Zip Code – State
0001 -10-      4      -    NULL      -- NULL – NULL – NULL
0002 – 11 – 3      -     Mark -   Huston ---75008 – TX
0003 – NULL – NULL – John – Dallas – NULL – NULL
0004 – NULL – NULL – NULL – NULL – 75008 – TX
Thanks for your help in this.

I am including you a full example:
create table TableA (BPID VARCHAR(4), Cost INT, Profit INT)
create table TableB (BPID VARCHAR(4), Name VARCHAR(MAX), Address VARCHAR(MAX))
create table TableC (BPID VARCHAR(4), ZipCode VARCHAR(5), State VARCHAR(2))
INSERT INTO TableA VALUES('0001',10,4),('0002',11,3)
INSERT INTO TableB VALUES('0003','John','Dallas'),('0002','Mark','Huston')
INSERT INTO TableC VALUES('0004','74001','TX'),('0002','75008','TX')
SELECT ISNULL(ISNULL(TableA.BPID, TableB.BPID), TableC.BPID) AS BPID,
TableA.Cost, TableA.Profit, TableB.Name, TableB.Address, TableC.ZipCode, TableC.State FROM TableA
FULL OUTER JOIN TableB ON (TableA.BPID = TableB.BPID)
FULL OUTER JOIN TableC ON (TableB.BPID = TableC.BPID)
And the results:
