Question

Write a single join to get a table of results containing the name of each clown and the name of that clown's boss from identical tables called clown_info1 and clown_info.

Answer 1

To join two identical tables, clown_info1 and clown_info, to get a table of results containing the name of each clown and their boss, you can use a single JOIN statement in SQL.

Step-by-step explanation:

To get a table of results containing the name of each clown and the name of that clown's boss from identical tables called clown_info1 and clown_info, you can use a single JOIN statement in SQL. The JOIN statement combines rows from two or more tables based on a related column between them. In this case, you would join the two tables on a common column, such as the clown's ID or the boss's ID.

Here is an example of how the JOIN statement could be written:

SELECT clown_info1.name AS Clown, clown_info.name AS Boss
FROM clown_info1
JOIN clown_info ON clown_info1.boss_id = clown_info.id;

In this example, clown_info1 is the table containing the clown's information, and clown_info is the table containing the boss's information. The JOIN is based on the condition that the boss_id in clown_info1 matches the id in clown_info.
