93. Extract the Email Domain

There is no SPLIT_PART in SQLite, so to grab the part of an email after the @ you combine instr and substr. instr(email,'@') returns the 1-based position of the @; everything after it starts one character later.

Task: for each user return id, email, and domain — the substring of email after the @ sign. Use substr(email, instr(email,'@') + 1) (the two-argument substr returns from a start position to the end of the string). Order by id.

Output columns, in order: id, email, domain.
