Stats gathering pl/sql syntax

Question

Hi All:
I'm trying to write PL/SQL to conditionally either run or delete table stats (I am on 10.2.0.3):
The table name is a variable, something like that:
exec dbms_stat.delete_table_stats('MYOWNER','v_table_name');
else
exec dbms_stat.gather_table_stats(ownname=>'MYOWNER',tabname=>'v_table_name',estimate_percent=>'20', method_opt=>'for all column size SKEWONLY');
Two questions:
- what is the syntax to include the variable into the parameter list?
- is there any way to include more than 1 method_opt: ALL INDEXED and SKEWONLY
Thanks!

Answer 1

As 10g is already automatically gathering statistics,.why doe this at all?
Apart from that you would only need
create or replace procedure foo(p_owner in varchar2, p_table_name in varchar2, p_percent in number, p_opt in varchar2) is
begin
-- dbms_stat.delete_table_stats(p_owner,p_table_name);
dbms_stat.gather_table_stats(ownname=>p_owner,tabname=>p_table_name,estimate_percent=>p_percent, method_opt=>p_opt);
end;
exec foo('MY_OWNER' etc..
Just standard PL/SQL!
You only don't need to delete statistics. gather stats will take care of it
