I have a table with a column of varchar2(50) datatype. We are building a
new table and the values in this column should all be numbers. I need to
query the table to find all rows which have a value in this column which is
not a valid number.
Table:
circuit (circ_id (primary_key) number, circ_num varchar2(50))
Example: find all values in circ_num which are not numbers.
how do I do something like 'select circ_id, circ_num from circuit where
circ_num not valid to_number(circ_num)'
Is there a function to check this?
