ora-00997

this is my firt question here I have a problem trying to convert a table column (long raw) to a base 64 string, this column contains some of the employees pictures. This is the query, the field that i'm trying to convert is f.fot_empl : SELECT e.NOM_EMPL First_name, APE_EMPL Last_name, e.NOM_EMPL || ' ' || e.APE_EMPL Full_name, car.NOM_CARG position, COS.NOM_CCOS Area, f.fot_empl Picture, E.FEC_NACI Birth_date FROM EMPLE e INNER JOIN CONTR c ON E.COD_EMPL = C.COD_EMPL INNER JOIN cargo car ON C.COD_CARG = CAR.COD_CARG INNER JOIN CCOST cos on COS.COD_CCOS = C.COD_CCOS LEFT JOIN FOEMP f --

Here is a java procedure that returns the length of a LONG RAW. First,
