Solution 1

SQL

CREATE FUNCTION fn_FunctionName (@NO INT)
RETURNS TABLE
AS
RETURN
    (Select No,Name from TAB1 where No=@NO
    UNION
    Select No,Name,Class from TAB2 where No=@NO
    UNION
    Select Dept,Place   from TAB3 where No=@NO)
Go

Use it this way

SQL

SELECT * FROM fn_FunctionName(10)

The example is taken from here
MSDN: Create View[^]

This example uses the @@ROWCOUNT function as part of the view definition.
USE pubs
IF EXISTS (SELECT TABLE_NAME FROM INFORMATION_SCHEMA.VIEWS
      WHERE TABLE_NAME = 'myview')
   DROP VIEW myview
GO
CREATE VIEW myview
AS
   SELECT au_lname, au_fname, @@ROWCOUNT AS bar
   FROM authors
   WHERE state = 'UT'
GO
SELECT * 
FROM myview

As a view creates a virtual table you can then do most SQL operations on that view such as the simple example below

SQL

SELECT *
FROM myview
WHERE bar >= 10
