Database Query

Ruby
1

Hello.

Im trying to fetch a value from a field in our database, using this
code.

selected = @site.db.select(“select car from car_sale where id=402 AND
email=‘[email protected]’”)

But this throws the errormessage.
RemoteDatabase::Error: invalid environment

Does anybody knows how to get a value properly from the db?

Kind regards
-Erik

You’ll need to provide more info first.

(1) What database access library and version are you using? How did you
install it? Did you build any parts of it yourself? If so, what commands
did you use?
(2) What database and version are you talking to? Can you demonstrate
the same select query using a CLI client for that database?
(3) What code did you use to create @site.db?
(4) What version of Ruby are you running?
(5) What operating system are you running Ruby under?

(“ruby -v” gives a short answer to (4) and (5))

You specify here your table and fields, but no mention of the
database. How are you connecting to the database?
