# Weather Observation Station 15 in SQL | HackerRank Solution

Hello coders, today we are going to solve Weather Observation Station 15 HackerRank Solution in SQL.

## Problem

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.

1. select substr(round(long_w, 4),1,8) from station
where lat_n = (select max(lat_n)
from station where lat_n < 137.2345);

2. select substr(round(long_w, 4),1,8) from station
where lat_n = (select max(lat_n)
from station where lat_n < 137.2345);

3. correct query:

select cast(round(long_w,4) as decimal(10,4)) from station
where lat_n = (select max(lat_n) from station where lat_n < 137.2345);

4. FOR MS SQL SERVER:
SELECT TOP 1 CONVERT(DECIMAL(15,4),LONG_W) FROM STATION WHERE LAT_N<137.2345 ORDER BY LAT_N DESC
