Display Column as Rows (Transpose)

Hi,
I have a query like below which returns a single row and 5 columns. I would like to display it 5 rows in a single column. Basically switch columns to rows.
SELECT
round(sum(case when Column1 = ‘ABC’ then 1 0 end)) AS “CL1”,
round(sum(case when Column2 = ‘XYZ’ then 1 else 0 end)) AS “CL2”,
round(sum(case when Column3 = ‘PQR’ then 1 else 0 end)) AS “CL3”,
round(sum(case when Column4 = ‘EFG’ then 1 else 0 end)) AS “CL4”,
round(sum(case when Column5 = ‘HIJ’ then 1 else 0 end)) AS “CL5”,
FROM mytable
where {{Filter1}} and {{filter2}} and {{filter3}}
