سؤال
Am trying to use backreference expression to take out three subexpressions from a search, and reposition each subexpression as follows:
SELECT REGEXP_REPLACE('AAA 123 ppp','(^[[:alpha:]]+) ([[:digit:]]) ([[:alpha:]]+)','\3 \1 \2') from dual
However am getting the result as AAA 123 ppp where expecting ppp AAA 123 Where am i getting it wrong?
المحلول
Missing +
after [[:digit:]]
select regexp_replace('AAA 123 ppp','(^[[:alpha:]]+) ([[:digit:]]+) ([[:alpha:]]+)','\3 \1 \2')
from dual
ppp AAA 123
