Is it possible to give truncate rights to user A to truncate tables owned by user B?

But I should be able to truncate each table of B by A as per wish.

Some procedures would be needed I suppose? Kindly help!!

Platform - Oracle

You can give DROP ANY TABLE system privilege to A, then he will be able to truncate everything in any schema (not just in B's though) .

If you don't want to do that, a simple stored procedure created by B will do the job (procedure or function in Oracle are by default executed with definer rights) . Then you give need execute permission to A on this procedure. For instance,

create procedure truncate_my_table(tab_name varchar2)
as
begin
    execute immediate 'TRUNCATE TABLE ' || tab_name;
end;

You may also want to add parameter validation (for example, I'd do DBMS_ASSERT.ENQUOTE_NAME(DBMS_ASSERT.QUALIFIED_SQL_NAME(tab_name)) ) , error handling and logging to the procedure.

  • What is that tab name? Is it the table name? And why do we mention as varchar there? What if the user has 1000 tables? And user b needs to truncate only some tables of it? – tesla747 Sep 18 '15 at 18:06
  • user b calls this procedure to truncate table : execute a.truncate_my_table('table_1'); – a1ex07 Sep 18 '15 at 19:22
