Split FirstName and LastName in sqlite

Question

I have a table in sqlite db called [tblbook] with a column [authors]. What I am trying to do in the sql is to split the author values to firstname and the lastname and sort

Answer 1

Another way (a little shorter) to write this would be

SELECT 
  substr(BookAuthor, 1, instr(BookAuthor, ' ') - 1) AS first_name,
  substr(BookAuthor,    instr(BookAuthor, ' ') + 1) AS last_name
FROM tblBook where id=3
ORDER BY last_name

This would apply for version 3.7.15 and beyond.
