PLPGSQL: How can I get the effected rows when use "execute" command in function

[Muiz <work.muiz@xxxxxxxxx>]

Dear all,

   Can I get the effected rows after executing sqls in function?
e.g.:

CREATE OR REPLACE FUNCTION execsqls(sqls character varying)
  RETURNS integer AS
$BODY$
DECLARE
BEGIN
           EXECUTE sqls;
           -- TODO-1: I want to know how many records the input sqls effects?
           RETURN effectedRows;
END; 
$BODY$
  LANGUAGE plpgsql;

test: select  execsqls('update mytable where name like ''%abc''')

Regards,

Muiz
