如何从SQL Server 2000中的多个表中获取不同的行

Question

I have 3 tables. I want to combine these three tables and I need distinct rows only in SQL Server 2000

For example:

Table A

id
--
1  
2  
3  

Table B

id
--
2  
3  
4  

Table C

id
--
2  
3  
5  
6  

The results I want is:

id
--
1  
2  
3  
4  
5  
6  

Any suggestion would be helpful ...

Answer 1

Use UNION (without ALL ), something like this:

SELECT id 
FROM Table1
UNION
SELECT id
FROM Table2
UNION
SELECT id
FROM Table3
