Question

我正在尝试替换下面的文字以填充问号

SELECT REGEXP_REPLACE('?????/ ??????  John
??? ????? ??????? ?? ????? Pediatric Clinic ?? ??? 10 MAY 15 ?????? 01:15 PM
 ?????? ?????? ??? 15 ????? ?? ?????? ??????
Thanks.',
 '^[?/ ]+([a-z0-9 ]+)[?\s]+([a-z0-9 ]+)[?\s]+([0-9a-z ]+)[?\s]+([0-9a-z: ]+).+$','Mr/Ms \1, We would like to remind you about your appointment in \2 on \3 at \4. Please come 15 minutes before your appointment time. Thanks ',1,1, 'm') msg
FROM DUAL

但我总是得到相同的纠正字符串，即使匹配工作正常：

SELECT 'Ok' Result FROM DUAL WHERE REGEXP_LIKE('?????/ ??????  John
??? ????? ??????? ?? ????? Pediatric Clinic ?? ??? 10 MAY 15 ?????? 01:15 PM
 ?????? ?????? ??? 15 ????? ?? ?????? ??????
Thanks.',
'^[?/ ]+([a-z0-9 ]+)[?\s]+([a-z0-9 ]+)[?\s]+([0-9a-z ]+)[?\s]+([0-9a-z: ]+).+$', 'm')

Answer 1

这样的事情怎么样：

SELECT REGEXP_REPLACE('?????/ ??????  John
??? ????? ??????? ?? ????? Pediatric Clinic ?? ??? 10 MAY 15 ?????? 01:15 PM
 ?????? ?????? ??? 15 ????? ?? ?????? ??????
Thanks.',
 '[?/ ]*([^?[:cntrl:] ]*)[[:cntrl:]?/ ]*([^?]*) [?/ ]*([^?]*) [?/ ]*([^?[:cntrl:]]*)[[:cntrl:]?/ ]*([^? ]*)[?/ ]*([^? ]*)(.*)'
 ,'Mr/Ms \1, We would like to remind you about your appointment in \2 on \3 at \4. Please come 15 minutes before your appointment time. Thanks',1,1, 'm') msg
FROM DUAL;

你的正则表达式与你的第二行匹配（“??? ?????????????????????????????????????????????????? ?? 01:15 PM“）并用替换表达式替换你的第二行。

rexexp_replace无法按预期工作
