The following example copies a table to standard output, using a vertical bar \(\"|\"\) as the field delimiter:
COPY country TO stdout USING DELIMITERS '|';
COPY country TO stdout WITH DELIMITER '|';

You must have select access on any table whose values are read by " {} "COPY" {bold} ", and either insert or update access to a table into which values are being inserted by \

The keyword phrase " {} "USING DELIMITERS" {bold} " specifies a single character to be used for all delimiters between columns. If multiple characters are specified in the delimiter string, only the first \
