Query the smallest Northern Latitude (LAT_N) from STATION that is greater than 38.7780. 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 the smallest LAT_N ==> SELECT MIN(LAT_N)
• round answer to 4 deciaml places ==> SELECT ROUND(MIN(LAT_N), 4)
• from STATION table ==> FROM STATION
• greater than 38.7880 ==> WHERE LAT_N > 38.7780

SELECT ROUND(MIN(LAT_N), 4) 
FROM STATION 
WHERE LAT_N > 38.7780;

SELECT ROUND(LAT_N,4)
FROM STATION
WHERE LAT_N > 38.7780 
ORDER BY LAT_N LIMIT 1;
