I think the issue is whether the version of the sqlite drivers in
LiveCode are up to date enough to include foreign key support at
all. According to http://www.sqlite.org/foreignkeys.html, foreign

to find out what version of sqlite is included with LiveCode. If
foreign key support is included, it's off by default so you do have
to enable it as detailed by Trevor.
4.5 comes with 3.6.22. You can check the version of SQLite included
with the IDE by placing the following in a card script of a stack in
your plugin folder. Just make sure the card has a single field on it.
on preopenCard
put specialfolderpath("temporary") into theFolder
put theFolder & "/" & the milliseconds & ".db" into theFile
put revOpenDatabase("sqlite",theFile,,,,) into theConn
put revDataFromQuery(tab, cr, theConn, "SELECT sqlite_version()")
into theData
revCloseDatabase theConn
put "Installed SQLite version:" && theData into fld 1
delete file theFile
end preopenCard
