Exercise

Splitting house numbers with a delimiter

In the previous exercise, you used STRPOS(), LENGTH(), and SUBSTRING() to separate the actual house number for Queens addresses from the value representing a cross street. In the video exercise, you learned how strings can be split into parts based on a delimiter string value.

In this exercise, you will extract the house number for Queens addresses using the SPLIT_PART() function.

Instructions

100 XP
  • Write a query that returns the part of the house_number value after the dash character ('-') (if a dash character is present in the column value) as the column new_house_number.
