Values keyword can be used as below.
select * from (values ('test-a1', 'test-a2'), ('test-b1', 'test-b2'), ('test-c1', 'test-c2')) x(col1, col2)
The following will work for SQL:
SELECT 'test-a1' AS name1, 'test-a2' AS name2 UNION ALL SELECT 'test-b1', 'test-b2'UNION ALL SELECT 'test-c1', 'test-c2'
UNION ALL is the best bet. It's faster than UNION and you will have mutually exclusive rows.
