Rick,

If '_' is valid data, then why are you using to_number() to query the table
as it isn't actually numeric data?

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;
