Marcel, a fellow student was so kind to share his SQL code to add animals to our tables.
So if you would like to use that, just create an SQL File with the code below in Visual Studio and execute it.

This will delete (drop) the tables and refill them with the basic zoos and animals we had a the start.

drop table dbo.ZooAnimal
drop table dbo.Zoo
drop table dbo.Animal
 
CREATE TABLE [dbo].[Zoo] (
    [Id]       INT           IDENTITY (1, 1) NOT NULL,
    [Location] NVARCHAR (50) NOT NULL,
    PRIMARY KEY CLUSTERED ([Id] ASC)
);
 
CREATE TABLE [dbo].[Animal] (
    [Id]   INT           IDENTITY (1, 1) NOT NULL,
    [Name] NVARCHAR (50) NOT NULL,
    PRIMARY KEY CLUSTERED ([Id] ASC)
);
 
CREATE TABLE [dbo].[ZooAnimal] (
    [Id]       INT IDENTITY (1, 1) NOT NULL,
    [ZooID]    INT NOT NULL,
    [AnimalId] INT NOT NULL,
    PRIMARY KEY CLUSTERED ([Id] ASC),
    CONSTRAINT [AnimalFK] FOREIGN KEY ([AnimalId]) REFERENCES [dbo].[Animal] ([Id]) ON DELETE CASCADE,
    CONSTRAINT [ZooFK] FOREIGN KEY ([ZooID]) REFERENCES [dbo].[Zoo] ([Id]) ON DELETE CASCADE
);
 
insert into dbo.Zoo values ('New York')
insert into dbo.Zoo values ('Tokyo')
insert into dbo.Zoo values ('Berlin')
insert into dbo.Zoo values ('Kairo')
insert into dbo.Zoo values ('Milan')
 
insert into dbo.Animal values ('Shark')
insert into dbo.Animal values ('Clownfish')
insert into dbo.Animal values ('Monkey')
insert into dbo.Animal values ('Wolf')
insert into dbo.Animal values ('Gecko')
insert into dbo.Animal values ('Crocodile')
insert into dbo.Animal values ('Owl')
insert into dbo.Animal values ('Parrot')
 
insert into dbo.ZooAnimal values (1,1)
insert into dbo.ZooAnimal values (1,2)
insert into dbo.ZooAnimal values (2,3)
insert into dbo.ZooAnimal values (2,4)
insert into dbo.ZooAnimal values (3,5)
insert into dbo.ZooAnimal values (3,6)
insert into dbo.ZooAnimal values (4,7)
insert into dbo.ZooAnimal values (4,8)
insert into dbo.ZooAnimal values (5, 1)
insert into dbo.ZooAnimal values (5, 2)
insert into dbo.ZooAnimal values (5, 3)
insert into dbo.ZooAnimal values (5, 4)
insert into dbo.ZooAnimal values (5, 5)
insert into dbo.ZooAnimal values (5, 6)
insert into dbo.ZooAnimal values (5, 7)
insert into dbo.ZooAnimal values (5, 8)

Thanks to Marcel for sharing that. If you would like to see your code and examples added to the course, please let me know :)
