Sql Except query to Display mismatched records along with Table names

Question

Hi
I am using below query to display mismatch records between two tables
SELECT * FROM table1
EXCEPT
SELECT * FROM table2
UNION
SELECT * FROM table2
EXCEPT
SELECT * FROM table1
This displays mismatched records like below
Sunil  1000  india
Sunil 1500  india
I would like to display even the table names in the result For ex;
Sunil  1000  india  Table1
Sunil 1500  india   Table2
Can you please help us in this regard.

cnk_gr's query should work for you. 
One change that I would make is to use UNION ALL, not UNION.  UNION eliminates duplicate rows, which means SQL has to do additional work (sort the result and then check for duplicates). 
So if you can have duplicates and don't want them in your result, then you would use UNION.  And if you can have duplicates and you want the duplicates in the result, you would use UNION ALL.  But in cases like this, where you know you cannot have
duplicates (because column 1 contains 'TABLE1' for every row in the first half and column 1 contains 'TABLE2' for every row returned from the second half of the query), you should always use UNION ALL.  It will be more efficient.
