Which of these statements correctly satisfies the request: Display the message text where the message ID is greater than or equal to 4 and less than or equal to 8.

Question

BlackTom AI · Accepted Answer

The prompt is asking to display the message text for rows where message_id is between 4 and 8, inclusive.
Since the provided answer options are empty, there is only one candidate to evaluate: the single SQL statement given in the answer field.
Option evaluation will proceed as follows:

- The statement: SELECT message_text FROM message WHERE message_id BETWEEN 4 AND 8;
This correctly expresses the requested condition: message_id is greater than or equal to 4 and less than or equal to 8. The BETWEEN operator in SQL is inclusive, so it includes both endpoints 4 and 8, which matches the requirement.

- Clause analysis: The FROM clause specifies the table name as message, which is the appropriate source for message_text and message_id columns if those columns exist in that table. The SELECT clause chooses the message_text column, which is the data the query aims to display.

- Equivalence note: An equivalent but more verbose form could be: SELECT message_text FROM message WHERE message_id >= 4 AND message_id <= 8;
This is logically identical to the BETWEEN version and can be used in environments where BETWEEN is not preferred or supported.

- Potential edge cases: If the table or column names differ (for example, MESSAGE or MSG), the query would need to be adjusted to the actual schema. Also, if there are case sensitivity or quoting rules in the specific SQL dialect, identifiers might require different quoting.

- Absence of other options: Since no alternative answer choices were provided in the prompt, there is no comparative critique to perform. The analysis focuses on why the given statement satisfies the stated requirement and how it would behave in typical SQL databases.

In summary, the given SQL statement directly implements the requested condition (message_id between 4 and 8, inclusive) and selects the desired text column, making it correct under standard SQL semantics.
