To combine city and state into a single field prior to extraction, which SQL statement should be used?

Combining two text fields into one is done through string concatenation. The CONCAT function takes multiple strings and joins them into a single value, so you can create a single field like city and state together with a separator. For example, you’d write SELECT CONCAT(city, ', ', state) AS city_state FROM your_table, which yields entries like “Chicago, IL” in one field before you do any extraction or further processing. The other options serve different purposes: MERGE updates or inserts data into a target table from a source, JOIN brings rows from two tables together horizontally, and UNION stacks result sets vertically. None of those produce a single concatenated field from the two columns within one row.
