Final answer:
The statement is True; the OR operator in SQL means that at least one of the listed conditions must be met for the result to be included.
Step-by-step explanation:
The OR operator in an SQL statement means that at least one of the listed conditions must be met for the query to return a result. This logic is in line with the general definition of an OR event in Boolean operators, where an outcome is considered part of the event A OR B if it is in A, in B, or in both A and B. Therefore, the statement that 'the use of OR operator means that only one of the conditions in an SQL statement must be met' is True. This operator is particularly useful when you want to broaden your search results by allowing any of the search terms to appear in the outcomes.
SUMUP of the final answer:
- The OR operator in SQL is a Boolean operator that returns true if any of the conditions are met.
- It is used to broaden search results in a database query.
- The statement that only one condition must be met when using the OR operator is True.
The use of the OR operator in an SQL statement means that only one of the conditions must be met. It returns true if either of the conditions is true, and false if both conditions are false. For example, consider an SQL statement like SELECT * FROM students WHERE grade = 'A' OR grade = 'B'; This statement will retrieve all rows where the grade is either 'A' or 'B', or both.
