TO_NUMBER and ORA-01722 invalid number pls delete
542169Oct 26 2006 — edited Oct 26 2006I cannot see where to delete a post I made. I found out my problem. It was in my NLS settings. Decimals were set to be commas instead of periods.
please disregard this post, and delete if you are a moderator

I recently tried to bring in lat/long coordinates from a VARCHAR2 field (and even as a flat file) into a NUMBER field with a setup of NUMBER(20,13) to ensure I'd capture all of the signifigant digits.
I even ran this through a procedure to check if the data is a number first, and update only. I've found however that I keep getting the ORA-01722 invalid number error.
So I started testing out some points, and came across this:
select to_number('-79.662965387') from dual;
this query results in the invalid number error. I don't want to have to load these as an SDO GEOMETRY object, has anyone encountered this scenario before?
Or is my choice of 13 decimal places too high for Oracle?
