Query the Western Longitude (LONG_W) for the largest Northern Latitude (LAT_N) in STATION that is less than 137.2345 . Round your answer to 4 decimal places.

Input Format

The STATION table is described as follows:

where LAT_N is the northern latitude and LONG_W is the western longitude.

 

• query LONG_W ==> SELECT LONG_W
• round answer to 4 decimal places ==> SELECT ROUND(LONG_W, 4)
• in STATION table ==> FROM STATION
• LAT_N less than 137.2345 ==> WHERE LAT_N < 137.2345
• for the largest LAT_N ==> ORDER BY LAT_N DESC LIMIT 1

SELECT ROUND(LONG_W,4)
FROM STATION
WHERE LAT_N < 137.2345 
ORDER BY LAT_N DESC LIMIT 1;
