Re: one column reference multiple values in another table

[Peter Brawley]

Presumably, each referenced language can also be spoken by multiple, the relationship you're trying to model is many:many. That's done with a bridge table ...

table tbl( tid PK, ..., lang, ... )
table languages( lid PK, name, ...)
table tbl_languages( tid, lid )

... where each tbl_languages row documents one instance of one speaker of one language.
