oracle regular expression sub string and regular expression replace












-1















I have Phone_number column in my table where multiple numbers inserted with character values(eg.(123).254,5674). I need to compare each values without character string and needs to remove duplicate values.
Column value= '(245)289.4321,(897)201-7210,(897)2017210,8964253712'
I need to remove duplicates and only need distinct values. Thanks In advance for your help

    You are learning firsthand the need for first normal form in data normalization! Also why not to store formatting characters along with the data. If you have the power, fix the database design to eliminate multiple values in one column, which is the root cause of your issues here.

This should work:



with tmp_tbl as

(select '(245)289.4321,(897)201-7210,(897)2017210,8964253712' phone_numbers  from dual)

select distinct

  regexp_replace((regexp_substr(tmp_tbl.phone_numbers,'[^,]+', 1, level)),'D','') phone_number

from 

  tmp_tbl

connect by

  regexp_substr(tmp_tbl.phone_numbers,'[^,]+', 1, level) is not null


Result:



PHONE_NUMBER



8964253712



2452894321



8972017210
