Select table name

How can I select 'table name' in select clause if I use UNION ALL?
Example:
select * from table1
union all
select * from table2
union all
select * from table3

Now I want to see the tablename from where I'll get data.
Ex:
select x, * from table1 -- x - funtion/... that gives the table name
(table1)

Why don't you simply use string constants, like
SELECT 'table1' AS TableName, * FROM table1
UNION ...
