+ extended COPY TO ... DELIMITED ... / APPEND FROM ... DELIMITED ...
to support some other common formats.
COPY TO ... DELIMITED WITH TAB
APPEND FROM ... DELIMITED WITH TAB
uses chr(9) as field separator and without string delimiters
COPY TO ... DELIMITED WITH PIPE
APPEND FROM ... DELIMITED WITH PIPE
uses '|' as field separator and without string delimiters
COPY TO ... DELIMITED WITH ( { cStrDelim, cFldSeparator } )
APPEND FROM ... DELIMITED WITH ( { cStrDelim, cFldSeparator } )
allows users to set and any character field delimiters and fields
