Question

What is the purpose of the given SQL query?

1) To select data from the Person and Oscar tables
2) To count the number of Oscars for each person
3) To join the Person and Oscar tables
4) To order the results by the number of Oscars in descending order

Answer 1

The SQL query likely involves a SELECT statement with the possibility of JOIN, COUNT, GROUP BY, and ORDER BY clauses, each serving to combine data, count Oscars per person, and sort results respectively.

Step-by-step explanation:

The SQL query in question appears to serve multiple purposes. Without the actual query, I can only speculate based on the options provided. Typically, in SQL:

• To select data from the Person and Oscar tables would mean extracting data from these two tables, likely involving a SELECT statement.
• To count the number of Oscars for each person would involve the COUNT function, often used with GROUP BY to aggregate the results per person.
• To join the Person and Oscar tables usually implies the presence of JOIN clauses, which are used to combine the rows from the two tables based on a related column.
• To order the results by the number of Oscars in descending order would generally use the ORDER BY clause together with DESC to ensure that the data is sorted from the highest number to the lowest.

Without seeing the actual query, I cannot definitively say which purpose it serves. It could potentially meet all four objectives if it includes a SELECT statement with a JOIN clause, a COUNT function, GROUP BY, and an ORDER BY clause.
