[schema error] composite key

[leoeaton]

There are composite key sets in some tables according to the *.sql file. For example, in college_2 database, the 6th line in the file TextBookExample.sql says "primary key (building, room_number)", which indicate building and room_number are composite key of this table. However, in the tables.json, building is annotated as the only primary key of the table. I notice there are also some other databases where such issue exists.

Thanks for your report. We used a script to automatically extract schema info for each database. I am sure why this happens. I already recorded your findings [here(https://github.com//issues/24). We will correct the tables.json file in the next release. Please comment under that issue thread if you find more errors.
