select_all_horses(conn)5.8 LAB - Database programming with Python (SQLite)
Complete the Python program to create a Horse table, insert one row, and display the row. The main program calls four functions:
create_connection () creates a connection to the database.
create_table () creates the Horse table.
insert_horse () inserts one row into Horse.
select_all_horses () outputs all Horse rows.
Complete all four functions. Function parameters are described in the template. Do not modify the main program.
The Horse table should have five columns, with the following names, data types, constraints, and values:
\table[[Name,Data type,Constraints,Value],[Id,integer,primary key, not null,1],[Name,text,,'Babe'],[Breed,text,,'Quarter horse'],[Height,double,,15.3],[BirthDate,text,,2015-02-10'
