Kill a session dynanically using execute immediate

Goal

Solution

References

Applies to:

PL/SQL – Version: 8.1.7.4 to 10.1.0.2

Information in this document applies to any platform.

Goal

This article presents one suggested way of killing a session using an “ALTER SYSTEM KILL SESSION ‘sid,serial#’ ” statement in PL/SQL dynamically where the sid and serial# are values being passed in determined at runtime via additional SQL commands.

Solution

The Sid and serial values can be obtained from associated queries against the V$SESSION view.

For example, if a single user SCOTT was logged in and that is the session to kill, the following SQL can be used to obtain the required information:

SQL> select sid, serial# from v$session where username = ‘SCOTT’;

SID SERIAL#

—- ———-

26 10654

The SID (26) and Serial# (10654) are used within the following anonymous block to kill SCOTT’s session.

declare

sid number := 26;

serial number := 10654;

str varchar2(1000);

killstr varchar2(20);

begin

killstr := sid||’,’||serial;

str:=’alter system kill session ”’||killstr||””;

dbms_output.put_line(‘Kill String is ‘||killstr);

execute immediate str;

end;
