What SQL command is used to create a table using CSV format?

1. CREATE TABLE name USING excel

2. CREATE TABLE name USING json

3. CREATE TABLE name USING csv

4. CREATE TABLE name USING xml

The correct answer is: CREATE TABLE name USING csv

The command to create a table using the CSV format is indeed the one specifying "USING csv." This indicates that the table is being defined to directly read and interpret data formatted as CSV (Comma-Separated Values), which is a common and efficient format for storing tabular data. When you create a table in SQL, the "USING" clause specifies the data source format that will be utilized when reading data into the table. By using "csv," the system knows how to parse the incoming data files appropriately, recognizing the delimiter (comma) and any associated formatting that is standard for CSV files. The other options specify different formats—such as Excel, JSON, and XML—which each require their own specific parsing rules and structure. Therefore, they cannot be used to create a table intended for CSV data input. The clarity brought by using the correct format ensures efficient data management and retrieval in the Data Engineering context.
