Thank you kindly, Tlaukkan (Tommil) for a patch that:

Cleaned up schema creation scripts of MySQL to compliant form and created 
SQLite scripts from them. In future it would be optimal if scripts from 
different databases could be generated from MySQL scripts to ensure optimal 
consistency between schemas of different databases. Did not yet review 
column names. ID columns seem to have variety in naming which can be confusing.
