Which SQL keyword is used to provide additional instructions for a CREATE TABLE command when working with JSON?

1. USING

2. OPTIONS

3. WITH

4. WHERE

The correct answer is: USING

The correct response is that the keyword used to provide additional instructions for a CREATE TABLE command when working with JSON is "OPTIONS." This keyword allows you to specify various configurations and settings that tailor how the table will handle the JSON data format. In SQL, particularly within environments like Spark SQL, "OPTIONS" is employed to pass specific parameters related to data input methods, formats, compression, and other settings that can control the behavior of the table with the data source. For example, when creating a table using JSON data, you might include options to define the encoding or compression type, enabling you to optimize data retrieval and storage. The "USING" keyword is typically used to define the data source format (like JSON) but does not provide additional instructions directly. The "WITH" keyword can also signify certain options, but it is not specifically associated with JSON in this context. The "WHERE" keyword is used for filtering records based on conditions, which is beyond the scope of table creation. Therefore, “OPTIONS” is essential for fine-tuning how the JSON data is managed within the SQL command.
