I am trying to solve the question on HackerRank named Weather Observation Station 20, which you can find here which states:
A median is defined as a number separating the higher half of a data set from the lower half. Query the median of the Northern Latitudes (LAT_N) from STATION and round your answer to decimal places.
The STATION table is described as follows:
I am trying to submit this query as an answer:
SELECT ROUND(LAT_N, 4)
FROM STATION
ORDER BY LAT_N
LIMIT 1
OFFSET FLOOR((SELECT COUNT(LAT_N) FROM STATION)/2);`
where I am trying to locate the centre value. And for this query I am facing this error:
ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(SELECT FLOOR((SELECT COUNT(LAT_N) FROM STATION)/2))' at line 5
I am not sure what is the cause of error here.
