QUESTION: 27

Consider the following two statements:

Statement 1:

Statement 2:

How will the result sets differ for each statement when they are run in Databricks SQL?

The first statement will return all data from the customers table and matching data from the orders table.
The second statement will return all data from the orders table and matching data from the customers table. Any missing data will be filled in with NULL.
When the first statement is run, only rows from the customers table that have at least one match with the orders table on customer_id will be returned. When the second statement is run, only those rows in the customers table that do not have at least one match with the orders table on customer_id will be returned.
When the first statement is run, all rows from the customers table will be returned and only the customer_id from the orders table will be returned. When the second statement is run, only those rows in the customers table that do not have at least one match with the orders table on customer_id will be returned.
Both statements will fail because Databricks SQL does not support those join types.
