The " {} "BINARY" {bold} " keyword will force all data to be stored/read as binary objects rather than as text. It is somewhat faster than the normal copy command, but is not generally portable, and the files \

generated are somewhat larger, although this factor is highly dependent on the data itself. By default, a text copy uses a tab \

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 \
