How to select rows in this way ?????

Question

Hi All,
How to select tables from 2 table say client and vendor. Both have id, name. Now I want data of two tables using union but the data of one table come after another.
select id,name from vsg.client union select id,name from vsg.vendor
Eg.
Vendor Client
ID Name ID Name
1 ab 12 xyz
2 cd 13 wyx
3 ef 14 pqr
Now output should come like this
ID Name
1 ab (First rows from Vendor)
2 cd
3 ef
12 xyz (second rows from Client)
13 wyx
14 pqr
Thanks for your reply in advance......
