My Code: 

SELECT *
  FROM sqlite_master
  WHERE   
  LIMIT 5;
  
Replace this line with your code

What I expected to happen:

id code name area area_land area_water population population_growth birth_rate death_rate migration_rate
1 af Afghanistan 652230 652230 0 32564342 2.32 38.57 13.89 1.51
2 al Albania 28748 27398 1350 3029278 0.3 12.92 6.58 3.3
3 ag Algeria 2381741 2381741 0 39542166 1.84 23.67 4.31 0.92
4 an Andorra 468 468 0 85580 0.12 8.13 6.96 0.0
5 ao Angola 1246700 1246700 0 19625353 2.78 38.78 11.49 0.46

What actually happened:

type name tbl_name rootpage sql
table facts facts 47 CREATE TABLE “facts” (“id” INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, “code” varchar(255) NOT NULL, “name” varchar(255) NOT NULL, “area” integer, “area_land” integer, “area_water” integer, “population” integer, “population_growth” float, “birth_rate” float, “death_rate” float, “migration_rate” float) 
Replace this line with the output/error

You are not currently following the instructions exactly -

In a different code cell, write and run another query that returns the first 5 rows of the facts table in the database.

You need to return rows from the facts table.

Hi, Can anyone explain why do we have to run this query. I mean what does the output of this query is telling?

%%sql
SELECT ***
** FROM sqlite_master
** WHERE type=‘table’;**

Did you run

%%capture
%load_ext sql
%sql sqlite:///factbook.db

in the previous chunk?

Hi @midnight348 you can as well move to menu bar to restart and run the kernel, if that not working then confirm if you included the code below.

%%capture
%load_ext sql
%sql sqlite:///factbook.db
