問題文
A downstream system expects a comma-separated file whose first line lists the column names. Which part of the script controls whether that first line is written?
選択肢
- The body of the script, which must build the column names as the first element of the array, with the data rows following underneath them.
- A writer property on the output directive of the header, which can be turned off when the consumer does not want a column name row.
- The media type alone, because a comma-separated output always includes the column names and the only way to suppress them is to switch the output to plain text and assemble each line by hand in the body of the script.
- The connector that writes the file, not the script.
