Oracle 11.2.0.3 on Linux.

I need to execute this insert as select:

INSERT INTO TAB1 (SQL_ID,SQL_FULLTEXT)

      SELECT DISTINCT t.sql_id, t.sql_text FROM DBA_HIST_SQLTEXT;

But I get this error:

ORA-00932: inconsistent datatypes: expected - got clob

This is TAB1:

SQL_ID          VARCHAR2(13)                          

SQL_FULLTEXT    CLOB         Y                        

SQL_CUSTOM_HASH VARCHAR2(60) Y         

Should I user dbms_lob package? Is so, I do not understand how.

Thanks

M.
