I have a csv file which is in this format -

Can I create an external table for loading this file based on selection of fields driven by the record identifier which is the first field of each record, except for the firt two?
For e.g In the above file, for records which say 'abc' in it's first field, I want to load the 2,3,6,8 fields delimited by a comma (the values may as well be null in those fields) and for records which say 'Product' in their first fields, I want to load 5,8,9 and 10 fields from the same file. Basically, I want to know if we can use instr function while choosing the fields line by line based on a search criteria in the file. There will be less columns in my table than the number of fields in the csv file, so I guess I got to mention 'MISSING FIELD VALUES ARE NULL' option. There is another challenge too - I have to skip loading the first two lines from the file to the table.
I have written a big pl/sql proc for doing the same, using utl_file.get_line option, but it is still untested and I would be extremely happy to believe that this can be achieved by creating an external table too.

I'm trying to create a external table column validation.
I have data like this
First column is Numeric, second is Non-Numeric
1,X
2,Y
3,Z
There are chances that I may have data as following
1,X
2A,Y
3,Z
My requirement is whenever I get non-numeric data in first column I want to pass 0 or NULL. So, I have created a external table with following script.
CREATE TABLE EXT_test
(
SL NUMBER (4),
BRANCH_NAME VARCHAR2 (100)
)
ORGANIZATION EXTERNAL
(
[code]........
Following is the code for function is numeric
function isnumeric( p_string in varchar2) return boolean as
l_number number;
begin
l_number := p_string;
return TRUE;
exception
when others then
return FALSE;
end;
It is not recognizing function IS NUMERIC. Is there any way, I can do this through External Table.
I'm getting error like
The following error has occurred:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-00554: error encountered while parsing access parameters
KUP-01005: syntax error: found "identifier": expecting one of: "comma, date_format, defaultif, enclosed,
(, ltrim, lrtrim, ldrtrim, notrim, nullif, optionally, ), rtrim, terminated"
KUP-01008: the bad identifier was: isnumeric
KUP-01007: at line 9 column 16
ORA-06512: at "SYS.ORACLE_LOADER", line 14
ORA-06512: at line 1
