Write an SQL query to calculate the sum of all values in the columns LAT_N and LONG_W from the STATION table. Round the sums to a scale of 2 decimal places.

SQL Query

To calculate the sum of all values in the columns LAT_N and LONG_W from the STATION table and round the results to two decimal places, you can use the following SQL query:

SELECT 
    ROUND(SUM(LAT_N), 2) AS total_lat_n,
    ROUND(SUM(LONG_W), 2) AS total_long_w
FROM 
    STATION;

Explanation

1. SELECT: This statement retrieves specific columns or calculations.
2. ROUND: This function rounds the results to the specified number of decimal places (2 in this case).
3. SUM: This aggregate function calculates the total sum of the specified column values.
4. AS: This keyword gives a name (alias) to the resulting column in the output.
5. FROM STATION: Indicates the table from which to retrieve the data.

Final Answer

The query calculates the rounded sums of LAT_N and LONG_W from the STATION table as total_lat_n and total_long_w.
