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?

Normalization

Normalization is the process of eliminating redundancy in a database by organizing the data into several smaller tables. The large tables are normalized (converted) into smaller tables by using normalization rules, so that a database administrator can easily handle them. It also eliminates insertion, deletion, and update anomalies.
