#### Find the total value of all transactions for each day.

Given a table of transactions, this SQL query will find the total value of all transactions for each day.

#### Problem

```Given a table of transactions, write a SQL query to find the total value of all transactions for each day.
Example input:
| id | date       | value |
|----|------------|-------|
| 1  | 2019-01-01 | 100   |
| 2  | 2019-01-02 | 200   |
| 3  | 2019-01-03 | 300   |
Example output:
| date       | total_value |
|------------|-------------|
| 2019-01-01 | 100         |
| 2019-01-02 | 200         |
| 2019-01-03 | 300         |```

#### Solution

This solution is in SQL. Our A.I. can create solutions in multiple languages.
```SELECT date, SUM(value) AS total_value
FROM transactions
GROUP BY date;

/*

The solution above is optimal because it uses the GROUP BY clause to group the transactions by date.
The SUM function is used to sum the values of each group.

*/```

A.I. Evaluation of the Solution

The solution above is optimal because it uses the GROUP BY clause to group the transactions by date. The SUM function is used to sum the values of each group.
