Question

I have a database structure like this:

• Insured table

+-----------+--------------+-----+
| InsuredID |         Name | ... |
+-----------+--------------+-----+
|         1 |     John Doe | ... |
|         2 |   Bill Gates | ... |
|         3 |   Steve Jobs | ... |
+-----------+--------------+-----+

• Accompany table

+-------------+-----------+---------------+-----+
| AccompanyID | InsuredID |          Name | ... |
+-------------+-----------+---------------+-----+
|           1 |         1 |    Joanna Doe | ... |
|           2 |         1 |    Johnny Doe | ... |
|           3 |         3 | Steve Ballmer | ... |
+-------------+-----------+---------------+-----+

How can I have this result:

+----------------+-----+
|           Name | ... |
+----------------+-----+
|       John Doe | ... |
|     Joanna Doe | ... |
|     Johnny Doe | ... |
|     Bill Gates | ... |
|     Steve Jobs | ... |
|  Steve Ballmer | ... |
+----------------+-----+

How can I make the order of the query to be – Insured then Accompany‘s where the Accompany.InsuredID is equivalent to the Insured.InsuredID before the Accompany. It should be ordered like this:

1. John Doe (Insured) InsuredID = 1
2. Joanna Doe (Accompany) InsuredID = 1
3. Johnny Doe (Accompany) InsuredID = 1
4. Bill Gates (Insured) InsuredID = 2
5. Steve Jobs (Insured) InsuredID = 3
6. Steve Balmer (Accompany) InsuredID = 3

Answer 1

Something like this should work:

select name
from (
 select insuredid, name, 0 ins
 from insured
 union all
 select insuredid, name, 1 ins
 from  accompany) isq
order by insuredid, ins

Basically insert a fake column to identify what table the lines are coming from, then sort by insuredid, then by our arbitrary table number.
