Ruby SQlite SELECT Returning an Unwanted Array - sql

Question

I am trying to grab a couple values from an sqlite database, but instead of returning the value I am SELECT-ing, it is returning that value in an array inside of another array.
My code:
def self.find(id, database_connection)
name = database_connection.execute("SELECT name FROM pokemon WHERE id = ?", id)
type = database_connection.execute("SELECT type FROM pokemon WHERE id = ?", id)
pokemon_inst = Pokemon.new(id: id, name: name, type: type, db: database_connection)
end
The Problem:
When I run pry.binding
name outputs [["Pikachu"]]
type outputs [["electric]]
Is this working correctly? I can't imagine I should I just be calling name[0][0] to access the data, right?

Answer 1

The execute() method wraps everything it is returning in an array, and each database row is placed in an array. So, for the single value being queried to be in two arrays is correct.
Since everything is working as it should I will be adjusting my code to this:
def self.find(id, database_connection)
pokemon = database_connection.execute("SELECT * FROM pokemon WHERE id = ?", id).flatten
name = pokemon[1]
type = pokemon[2]
pokemon_inst = Pokemon.new(id: id, name: name, type: type, db: database_connection)
end
The adjustments are to flatten the array when it is assigned the queried data and to assign the individual values from that array.
