Continued with coding convention:

- added curly braces around conditional code blocks
- added space between if/foreach/... and brace
- rewrote a code block so if dbm::is_result() fails it will abort, else the id
  is fetched from INSERT statement
- made some SQL keywords upper-cased and added back-ticks to columns/table names
