Almost certainly somewhere in your column you have at least
one value that fails to convert to a number. Offhand, one
way that comes to mind to find that one value is to write a
loop inside a PL/SQL block that goes through your table
row-by-row doing the TO_NUMBER conversion. Wrap that
conversion in its own block, with an exception handler, and
you should be able to trap on the specific row having the
non-numeric value.
