※This sample exam is different from those that appear in the actual OSS-DB Exam.
By using the SQL COPY statement, you can copy the table contents to a file. If the output destination is STDOUT, it can be output to standard output instead of copying it to a file.
The syntax of the COPY statement is
COPY table name TO output destination [[WITH] (option)]
The default is tab-delimited in text format, but if you specify csv with the FORMAT option, it will be a comma separated CSV format. Alternatively, comma delimiting is also possible by setting the delimiter as a comma by the DELIMITER option.
Therefore, the correct answers are B and D.
Note that there are differences in the handling of special characters in the CSV format and the text format, so even if you set the delimiter as a comma with the DELIMITER option, it does not become a so-called CSV format.
