Load Numerical Column with Variable Comma

I'm using sqlldr to load a file which has a numerical value as one of its fields.

The problem is that in some of the records the number has commas whereas in other, it doesn't.

So doing something like

num "to_number(:num, '999,999,999.99')",

loads the records with commas but not those without commas and doing

num "to_number(:num)",

loads only those without commas.

Is there a way to tell Oracle (sqlldr) that the comma is optional?

Here you go:

SQL> desc loadertst;
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 COL1                                               NUMBER

SQL> !cat loadertst.ctl
load data
infile *
into table loadertst
fields terminated by ',' enclosed by '"'
(
col1 "to_number(replace(:col1,',',''))"
)
begindata
"123456"
"1,2,3,4,5,6"

SQL> !sqlldr phil/phil control=loadertst.ctl

Obviously you may need to fiddle with the fields terminated by ',' enclosed by '"' part to suit your data.
