Expert Solution & Answer
Chapter 4, Problem 13RQ
Explanation of Solution
The reason named constants are used:
The lexical analyzers collect the characters of the input string and group them into logical groups according to the pattern matching rules. These logical groupings are called as lexemes.
Lexical analyzer assigns some internal (numeric) codes to the lexemes (logical groupings) according to their structure. Instead of assigning numeric codes, named constants are used for token codes due to the following reasons:
- Gives better readability to the code...

The table includes columns about customer location such as city, state, and country. You want to retrieve the first 3 letters of each country name. You decide to use the SUBSTR function to retrieve the first 3 letters of each country name, and use the AS command to store the result in a new column called new_country. You write the SQL query below. Add a statement to your SQL query that will retrieve the first 3 letters of each country name and store the result in a new column as new_country.arrow_forward
