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.
