OK, I knew about the SHOW CREATE TABLE command, but thought perhaps MySQL had the equivalent of the SQLite sqlite_master table 'table' entries.

Out of interest, where does mySQL store the SQL statements to create tables? (still finding my way around mySQL!)

So if you are doing a line offset to find let's say "CREATE TABLE devices" and the person who created the table used quotes you will not find that line! Apparently, sqLite records the exact sequel used to create the table, not the sanitized SQL that would be used to do it, like in mySQL. (but I could be wrong about mySQL being sanitized).
