Does franca support join query? how hard is it to implement this lib using ruby?

[ruichao-factual]

Sometimes, we need to fetch data that are stored in multi tables, especially for relational database. Does franca-js support this kind of query?

Another question, is it hard to implement a similar lib using ruby?

[chen-factual]

Yes, not but directly. We specify a table field that goes into the SQL query, i.e. SELECT * FROM table. So for the table field you can actually drop a join, like if you set table: "tabA INNER JOIN tabB ON tabA.id = tabB.id", your select query will beSELECT * FROM tabA INNER JOIN tabB ON tabA.id = tabB.id`.

Another question, is it hard to implement a similar lib using ruby?

All Franca does is translating a map to a string (Postgres, Solr) or another map (Mongo), so it's should be totally doable in Ruby. When Fanchen's done with re-architecting for writes, it shouldn't be difficult to do a Ruby port if that's desired (I'm guessing for rails?)
