SELECT DISTINCT ParamValue from (

SELECT 'ABC' AS Attri1,'Yes' AS ParamValue

UNION ALL

SELECT 'PQR' AS Attri1,'Yes' AS ParamValue

UNION ALL

SELECT 'XYZ' AS Attri1,'Yes' AS ParamValue

UNION ALL

SELECT 'ABC' AS Attri1,'No' AS ParamValue

UNION ALL

SELECT 'PQR' AS Attri1,'No' AS ParamValue

) X
