Solution

To retrieve hours from the date field in the transactions table and name the resulting field hours, you would use the EXTRACT function in SQL. Here's how you can do it:

SELECT EXTRACT(HOUR FROM date) AS hours
FROM transactions;

In this SQL statement:

  • EXTRACT(HOUR FROM date) is used to get the hour from the date field.
  • AS hours is used to name the resulting field as hours.
  • FROM transactions specifies the table from which to retrieve the data.

Please replace date with your actual date column name. Also, note that the EXTRACT function might work differently in different SQL dialects.
