Invalid number (01722) in Oracle 10g

Hello, everyone,

I have an Oracle 10g database, and in it is a table where the first column is a VARCHAR 36 and contains Oracle generated UIDs.

I am trying to run a SELECT query that gets a corresponding (date 19)  where the UID = '{ a 36 character long UID}'.  I am getting the  ORA-01722 invalid number error message.

SELECT s.ENTERED_DATEFROM dsp.status sWHERE s.UID = '4a29d12025012995c231f18eb7704009'

I've tried using TO_CHAR() and CAST() to no avail.  What am I missing?

V/r,

^_^
