Answer 1

select name,
    Country,
    case NORMAL_STATE
        when 1 then 'OPEN'
        when 0 then 'CLOSED'
        else 'UNKNOWN'
    end as NORMAL_STATE,
    case CURRENT_STATE
        when 1 then 'OPEN'
        when 0 then 'CLOSED'
        else 'UNKNOWN'
    end as CURRENT_STATE
from SOMS_TABLE
where name like 'AR%'
    and NORMAL_STATE <> CURRENT_STATE
order by Country 

Answer 2

これを使って

CASE NORMAL_STATE
    WHEN 1 THEN 'OPEN'
    WHEN 2 THEN 'CLOSED'
END AS NORMAL_STATE

同様にCURRENT_STATE

Answer 3

IFステートメントを使用できます

SELECT NAME, Country, 
       IF(NORMAL_STATE > 0,'OPEN','CLOSED'), 
       IF(CURRENT_STATE > 0,'OPEN','CLOSED') 
FROM SOMS_TABLE 
WHERE SOMS_TABLE.NAME LIKE 'AR%' AND 
      NORMAL_STATE <> CURRENT_STATE 
ORDER BY SOMS_TABLE.Country ASC
