Low-Budget Pokémon
You begin your journey as a trainer with the goal of becoming champion.
Leon-Jason M.
Today is a big day.
You're setting off on your journey to become your region's Champion.
Of course, it won't be easy.
First, you have to beat all the Gyms and take on the Elite Four.
But you're not there yet. Get an overview of all the Pokémon in your region. Return all columns from `Pokedex`.
select * from Pokedex
Unfortunately, you can't start with just any Pokémon. Show all the starters in `Pokedex`, including every column.
Select * from Pokedex where IsStarter = 'Yes'
Now that you've met your future battlers, it's time to face your first challenge.
The first Gym Leader is Roark. Take a look at his team. Return all columns from `OpponentTeam` and `Pokedex`.
Hint: Use `JOIN` to connect `OpponentTeam` and `Pokedex` through `NatDex`. Then filter `OpponentTeam.Name` for the Gym Leader.
Select * from OpponentTeam join pokedex on pokedex.natdex = OpponentTeam.natdex where Name = 'Roark'
Now look for Pokémon that can hit his team super effectively (`Strong`). Find Pokémon whose type is super effective against Roark's Rock Pokémon. Return all columns from `Pokedex` and `TypeChart`.
In this game, only the type stored in `Pokedex.Type` counts for each Pokémon. `Strong` lists opposing types that this type hits super effectively; `Resists` and `Immune` refer to incoming attacks.
select * from pokedex join typechart on typechart.type = pokedex.type where strong like '%rock%'
Join `Pokedex` and `TypeChart` through `Type`. The fields contain lists; use `LIKE` to search `Strong`. Put `%` before and after the search text to find the type anywhere in a list.
Woohoo, you did it.
You're practically the Champion already.
Well, not quite.
Your next challenge is Maylene. You know the drill. Take a look at her team. Return all columns from `OpponentTeam` and `Pokedex`.
select * from OpponentTeam join pokedex on OpponentTeam.natdex = pokedex.natdex where name = 'Maylene'
Maylene's team is pretty strong. Luckily, some Pokémon are immune to Fighting moves. Find these Pokémon and return all columns from `Pokedex` and `TypeChart`.
Hint: Just like with Roark, use `LIKE` to search a field. This time, search `Immune`.
select * from Pokedex join TypeChart on pokedex.type = typechart.type where Immune like '%fighting%'
Wow. You're practically halfway there.
Oh, and someone has a crazy plan to reshape the universe, but luckily, that's not your problem.
While that's going on, you face the next Gym Leader: Candice.
Go on, take a look at her team. Return all columns from `OpponentTeam` and `Pokedex`.
select * from OpponentTeam join pokedex on OpponentTeam.natdex = pokedex.natdex where name = 'Candice'
Unluckily for her, Ice is a really weak type. Find out which Pokémon resist Ice moves. Return all columns from `Pokedex` and `TypeChart`.
Hint: Use `LIKE` to search `Resists`.
select * from pokedex join typechart on pokedex.type = typechart.type where resists like '%ice%'
After leaving the Gym, you notice something strange on Mount Colossus. A madman, a kid, and a Legendary Pokémon are standing on a mountain. Sounds like the start of a bad joke.
Luckily, it's still not your problem.
A few days later, you finally reach Victory Road. Just a few more battles before you can challenge the Champion.
Flint is the last obstacle between you and the Champion. But his team is a little... different this time. Look at his team with the details from `Pokedex`. Return all columns from `OpponentTeam` and `Pokedex`.
select * from OpponentTeam join pokedex on OpponentTeam.natdex = pokedex.natdex where name = 'Flint'
This time, no Pokémon has the perfect type. So let's see how strong his team is. `BST` is a Pokémon's base stat total: the sum of its base stats.
Calculate the average `BST` of Flint's team. Return only this average.
Hint: Use `AVG(BST)` to calculate the average `BST`.
select AVG(BST) from pokedex join OpponentTeam on OpponentTeam.natdex = pokedex.natdex where name = 'Flint'
Now look for stronger Pokémon. Their `BST` must be higher than the average `BST` of Flint's team. Return all columns from `Pokedex`.
(In case you didn't remember: `AVG(BST)` for Flint's team = 504.4.)
SELECT * FROM Pokedex WHERE BST > 504.4
So, here you are, facing the Champion. You've overcome plenty of challenges and learned a lot.
Like Flint's team, Cynthia's team has a mix of types. Once again, you can't rely on `TypeChart` alone. Calculate her team's average `BST` too. Return only this average.
select AVG(BST) from pokedex join OpponentTeam on OpponentTeam.natdex = pokedex.natdex where name = 'Cynthia'
There aren't many Pokémon with a `BST` above 535. Still, take a look at them. Return all columns from `Pokedex`.
select * from pokedex where BST > 535
Her strongest Pokémon is Garchomp. Perhaps there's a Pokémon with a `BST` above 535 that can hit Garchomp super effectively. Find Pokémon whose type is super effective against Dragon Pokémon. Return all columns from `Pokedex` and `TypeChart`.
Hint: Both conditions must hold: `BST` above 535 and Dragon in `Strong`. Combine them with `AND`.
select * from pokedex join typechart on pokedex.type = typechart.type where BST > 535 AND strong LIKE '%dragon%'
Garchomp is still very strong. Perhaps there's a Pokémon that's immune to its Dragon moves. Find such Pokémon with a `BST` above 535. Return all columns from `Pokedex` and `TypeChart`.
SELECT * FROM Pokedex JOIN TypeChart ON Pokedex.Type = TypeChart.Type WHERE BST > 535 AND Immune LIKE '%dragon%'
And sure enough, Garchomp goes down. You've won!
You're your region's Champion. But your journey doesn't have to end here. There's still plenty to discover.
This story, however, ends here.
