Can someone share any function which can allow to insert BLOB data into
Varchar2 column? Most of the BLOB data is less than 32K but selecting the BLOB
using dbms_lob.substr( l_cur.mylob, 32000, 1 ) or utl_raw.cast_to_varchar2 gave
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
Can someone share an example to convert data from BLOB to varchar ?
