To answer this question, you need to understand the concept of set operators in Oracle SQL and their precedence.
Set operators in Oracle SQL are used to combine the result sets of two or more SELECT statements. These set operators include UNION, UNION ALL, INTERSECT, and MINUS.
In Oracle SQL, all set operators have equal precedence. This means that when multiple set operators are used in a single query, they are evaluated from left to right, regardless of the specific operator.
Therefore, the correct answer is:
A. True - This option is correct because all set operators in Oracle SQL have equal precedence.
