You are working with a database table that contains employee data. The table includes columns about employee location such as city, state, country, and postal_code. You want to retrieve the first 3 characters of each postal code. You decide to use the SUBSTR function to retrieve the first 3 characters of each postal code, and use the AS command to store the result in a new column called new_postal_code.  You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 characters of each postal code and store the result in a new column as new_postal_code.  NOTE: The three dots (...) indicate where to add the statement.     1 2 3 4 5 6 7                   SELECT employee_id, ... FROM employee ORDER BY postal_code                       RunReset What employee ID number appears in row 5 of your query result?
