Hello experts,

we need a query to retrieve the employee location country name but below it extracts country code.

Is it possible to retrieve the entire country name?

SELECT L.COUNTRY FROM HR_LOCATIONS_ALL L,PER_ALL_ASSIGNMENTS_M ASG
WHERE
ASG.ASSIGNMENT_ID =:{PARAMETER.ASSIGNMENT_ID}
AND TRUNC(SYSDATE) BETWEEN TRUNC(ASG.EFFECTIVE_START_DATE) AND TRUNC(ASG.EFFECTIVE_END_DATE)
AND ASG.LOCATION_ID=L.LOCATION_ID
AND TRUNC(SYSDATE) BETWEEN TRUNC(L.EFFECTIVE_START_DATE) AND TRUNC(L.EFFECTIVE_END_DATE)

Thanks in advance for your time!
