Hi All,
From: James Cloos
The E'' syntax eats your backslashes. For that version, try just:
SELECT REGEXP_REPLACE(LOWER('300 North 126th Street'),'(\d)(st|nd|rd|th)',
'\1', 'g');
Actually, I found that the double backslashes are required whether the E is
used or not:
development=# select regexp_replace('300 North 126th Street',
'(\d+)(?:st|nd|rd|th)', '\1', 'gi');
WARNING: nonstandard use of escape in a string literal
LINE 1: select regexp_replace('300 North 126th Street', '(\d+)(?:st|...
^
HINT: Use the escape string syntax for escapes, e.g., E'\r\n'.
WARNING: nonstandard use of escape in a string literal
LINE 1: ...'300 North 126th Street', '(\d+)(?:st|nd|rd|th)', '\1', 'gi'...
^
HINT: Use the escape string syntax for escapes, e.g., E'\r\n'.
