# Project Euler in PL/SQL: Problem 13

Problem 13 of Project Euler is a bit different than the others we’ve done; we don’t even need to us PL/SQL to solve it!

## Problem 13:

### Large Sum

Work out the first ten digits of the sum of the following one-hundred 50-digit numbers.

……

To solve this problem, I simple imported the 100 numbers into a table in SQL, then ran a SUM function on the first 11 digits to find what the first 10 would be.

```
SELECT SUM(SUBSTR(num,1,11)) FROM num_input;

--output: 5537376230
```
