Question
What is the issue with the below queryselect* from film_actor having actor_id=10a.None from the provided optionsb.Having will not with out where clausec.Produce result with Incorrect Valuesd.Produce Result with correct valuese.
Solution
The issue with the query is option b. "Having will not work without a where clause".
The HAVING clause is used in the SELECT statement to specify filter conditions for a group of rows or aggregates. The HAVING clause is often used with the GROUP BY clause to filter groups or aggregates based on a specified condition.
However, in the provided query, there is no GROUP BY clause, and the HAVING clause is being used like a WHERE clause. The WHERE clause is used to filter records before any groupings take place.
So, the correct way to write the query would be:
SELECT * FROM film_actor WHERE actor_id = 10
This will return all records from the film_actor table where the actor_id is 10.
