In 8i you can use ... (straight from SQL reference manual)

TO_LOB Purpose Converts LONG or LONG RAW values in the column long_column to LOB values. You can apply this function only to a LONG or LONG RAW column, and only in the SELECT list of a subquery in an INSERT statement (see "INSERT" on page 7-512).
Before using this function, you must create a LOB column to receive the converted LONG values. To convert LONGs, the LOB column must be of type CLOB or NCLOB. To convert LONG RAWs, the LOB column must be of type BLOB.

TO_LOB ( long_column )

Example Given the following tables:

CREATE TABLE long_table (n NUMBER, long_col LONG); CREATE TABLE lob_table (n NUMBER, lob_col CLOB);

use this function to convert LONG to LOB values as follows:

INSERT INTO lob_table
SELECT n, TO_LOB(long_col) FROM long_table;
