How to get combined output from two or more than two queries?

Question

I have one table ABC . I am using queries

select count(*) from ABC where COLA=123; //output is 3

select count(*) from ABC WHERE COLA=321; //output is 6

I want both output combined like

| someColumnName |
|    3           |
|    6           |

Is there any way to frame query so that I can achieve this?

Answer 1

Use UNION between your two queries:

select count(*) as someColumnName  from ABC where COLA=123
union
select count(*) from ABC WHERE COLA=321;

Answer 2

use a group by and where clause.

SELECT count(*) as SomeColumnName
FROM ABC 
WHERE COLA in (123,321)
GROUP BY ColA

Answer 3

Just another option:

SELECT count(*) as SomeColumnName
FROM ABC 
WHERE COLA = 123 
   OR COLA = 321
GROUP BY COlA;
