Write your own function (or use Oracle functions) that filters these characters before applying to_number.
For example: to_number(replace ('1234-123','-',''))

Hi,

I have a table with a column defined as varchar. This field will always have numbers but some of them have underscores in the data which is also valid
data. I want to be able to query the table using a to_number() in the where clause. Obviously I am getting ora-1722.

I cannot apply clause to try to filter the '_' data out as it will do a FTS and apply to_number to that field anyway.

Any suggestions?

Thanks
Rick

SELCT *
FROM <table>
WHERE TO_NUMBER(<field>) BETWEEN 10 AND 10000;
