Jack,

  It used to be DELETE ANY TABLE. I'm not sure if that has changed in recent versions. Long ago, I setup the following procedure to allow a specific table to be truncated, without out the DELETE ANY TABLE privilege. It must be owned by the owner of the table. I haven't dealt with this issue in years, so if things have changed since Oracle 7, somebody else can chime in.

CREATE OR REPLACE PROCEDURE TRUNC_TAB
(TAB_IN IN USER_TABLES.TABLE_NAME%TYPE)
-- Author : Tony Ziemba Sheck Cho 4/18/95

• Modified :
• 10/14/97 JMH
• 08/06/99 JMH Allow only certain tables to be truncated.
• 08/08/99 JMH Added more tables.
• Description:
• This procedure was developed to truncate a table using the table name that is
• passed in as an input parameter. This procedure illustrates the use of the
• dbms_sql package to execute SQL DDL statements within PL/SQL. As of v7.1
• TRUNCATE cannot be executed on a table unless the user owns the table or
• the user has DELETE ANY TABLE privelege. This procedure is a workaround to
• those limitations.
  --
  AS cursor_id integer; -- holds cursor id return_value integer; -- holds call return value str varchar2(150); -- string to hold DDL statement e_wrongtable exception; -- exception when truncate is done on other tables. BEGIN IF tab_in in ('TS_SECURITY_ACCESS','GL_CODE_COMBINATIONS') THEN str := 'truncate table '||tab_in; cursor_id := dbms_sql.open_cursor; dbms_sql.parse ( cursor_id,str,dbms_sql.native);
• DDL statements are executed immediately. This may change
• in future releases, in which case the following statement will
• be needed.
• return_value := dbms_sql.execute(cursor_id); dbms_sql.close_cursor(cursor_id); ELSE RAISE e_wrongtable; END IF; EXCEPTION WHEN e_wrongtable THEN RAISE_APPLICATION_ERROR(-20000,'Procedure restricts tables that can be truncated.'); WHEN OTHERS THEN dbms_sql.close_cursor(cursor_id); END; /

Hi

I need to create a user/role that among other stuff must be able to truncate a table. I can't figure out which privileges are needed (DBA is a bit OTT :-))
Try them one by one does not sound appealing at all

TIA Jack
