How to use union all with manual value (not from another tabel)?

Question

I want to use union all with manual value, not from another table. And the values are:

|cSatuan1|cSatuan2|nkonversi|
=============================
|   LTR  |   PCS  |    1    |
|   PCS  |   LTR  |    1    |

I've made the query with my own way, but it gets error. here is the query:

SELECT csatuan2, csatuan1, nkonversi
FROM ms_metriks union all select 'LTR','PCS','1','PCS','LTR','1'

Can you tell me what's wrong with my query, and what is the right query?

Answer 1

Try this:

SELECT csatuan2,csatuan1,nkonversi FROM ms_metriks 
UNION ALL SELECT 'LTR','PCS','1'
UNION ALL SELECT 'PCS','LTR','1'

Answer 2

Here is one way you can do it:

SELECT 'LTR' as csatuan1,'PCS' as csatuan2,'1' as nkonversi
UNION
SELECT 'PCS','LTR','1';
