Can't import csv fields starting with double quotes but lack ending ones

Question

Hi all,
When I'm trying to used external table to import a csv file, specified as using comma as delimiter optionally enclosed by double quotes, some records are rejected because a field in the record has starting double quotes, but without ending ones.
Assume the customer really want these starting double quotes, how do I change my external table specification such that these starting double quotes are treated as part of the field data and can be successfully inserted into db?
Many thanks.

I have no access to Oracle during weekends, so nothing can be tested. So here it goes:
Suggestion: DELIMITED BY '","' and of course omitt ENCLOSED BY '"'
You will have to update each row of the rows just loaded setting the first_field to substr(first_field,2) and the last_field to substr(last_field,-2)
If all the fields are not enclosed in double quotes (TRUE for strings and FALSE for numbers and dates) the situation (syntax diagrams allow two delimiters only) is somehow more complicated, anyway you can specify DELIMITED BY ',' and update all varchar2 fields in each row of the rows just loaded setting the varchar2_field to substr(varchar2_field,2,length(varchar2_field) - 2).

After posting I noticed it's difficult to distinguish between single and double quotes:
the first DELIMITED BY should read {single quote){double quote}{comma}{double quote}{single quote)
the ENCLOSED BY should read {single quote){double quote}{single quote)
