[sql] How do you manually execute SQL commands in Ruby On Rails using NuoDB

I'm trying to manually execute SQL commands so I can access procedures in NuoDB.

I'm using Ruby on Rails and I'm using the following command:

ActiveRecord::Base.connection.execute("SQL query")

The "SQL query" could be any SQL command.

Like for example I have a table called "Feedback" and when I execute the command:

ActiveRecord::Base.connection.execute("SELECT `feedbacks`.* FROM `feedbacks`")

This would only return a "true" response instead of sending me all the data requested.

This is the output on the Rails Console is:

SQL (0.4ms)  SELECT `feedbacks`.* FROM `feedbacks`
 => true

I would like to use this to call stored procedures in NuoDB but upon calling the procedures, this would also return a "true" response.

Is there anyway I can execute SQL commands and get the data requested instead of getting a "true" response?

res = ActiveRecord::Base.connection_pool.with_connection { |con| con.exec_query( "SELECT 1;" ) }

The above code is an example for

1. executing arbitrary SQL on your database-connection
2. returning the connection back to the connection pool afterwards

Reposting the answer from our forum to help others with a similar issue:

@connection = ActiveRecord::Base.connection
result = @connection.exec_query('select tablename from system.tables')
result.each do |row|
puts row
end

For me, I couldn't get this to return a hash.

results = ActiveRecord::Base.connection.execute(sql)

But using the exec_query method worked.

results = ActiveRecord::Base.connection.exec_query(sql)
