Is this what you are looking for:

TO_LOB 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.

Before using this function, you must create a LOB column to receive the converted LONG values. To convert LONGs, create a CLOB column. To convert LONG RAWs, create a BLOB column.

See Also: INSERT for information on the subquery of an INSERT statement  
 
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;
