oracle sql string split

Hi - I have a string like "LNAME, FNAME MNAME SURNAME"
I am trying to write query in oracle to get just the FNAME and LNAME excluding others.

1) data is comma seperated
2) the data before comma is LNAME and first word after comma is FNAME.

How can I get that.

Thanks

your sample data is not completely comma separated, but this should handle it regardless of using commas, spaces or both

select regexp_substr(yourstring,'[^, ]+',1,1) lname,
       regexp_substr(yourstring,'[^, ]+',1,2) fname
from yourtable

assuming the data is formatted as you have shown then try this...


SELECT SUBSTR(yourstring, 1, INSTR(yourstring, ',') - 1) lname,
       SUBSTR(
           yourstring,
           INSTR(yourstring, ', ') + 2,
             INSTR(
                 yourstring,
                 ' ',
                 1,
                 2
             )
           - INSTR(yourstring, ', ')
           - 2
       )
           fname
  FROM yourtable

if the data is formatted as you described  - that is, actually comma separated, not commas and spaces

so something like "LNAME,FNAME,MNAME,SURNAME"

then try this...


SELECT SUBSTR(yourstring, 1, INSTR(yourstring, ',') - 1) lname,
       SUBSTR(
           yourstring,
           INSTR(yourstring, ',') + 1,
             INSTR(
                 yourstring,
                 ',',
                 1,
                 2
             )
           - INSTR(yourstring, ',')
           - 1
       )
           fname
  FROM yourtable

The question that needs to be answered is, "Are there commas and/or spaces between each word and are there possible combinations of one or the other or both?
