Обсуждение: Entering a character code in a query
I would like to use the following query:
SELECT english || '\n' || english || '\x2028' || french AS output FROM vocab_words_translated;
where \x2028 is the hexadecimal code for a soft carriage return.
However, this does not work.
Can anyone help with this problem?
Thanking you,
John
Pertinent codes:
2028 LINE SEPARATOR * may be used to represent this semantic unambiguously
U+2028, character
, decimal 8232, hex 0x2028, octal \20050, binary 10000000101000UTF-8: 0xe2 0x80 0xa8 John Gage wrote: > I would like to use the following query: > > SELECT english || '\n' || english || '\x2028' || french AS > output FROM vocab_words_translated; > > where \x2028 is the hexadecimal code for a soft carriage return. > > However, this does not work. > > Can anyone help with this problem? If you have PostgreSQL 8.4 with standard_conforming_strings = on, you could write: english || E'\n' || english || U&'\2028' || french Otherwise, you have to resort to english || E'\n' || english || chr(8232) || french (provided your server_encoding is UTF8).

I would just like to thank Albe and Jasen for their responses. What an extraordinary environment Postgres is! Human and computing.

you could write:
