Hi everyone,

I'm doing a TPCH-H academic benchmark and I'm now runiing explain plans for my queries before doing dbms_stats.
The problem is that, no matter how I get the explain plans, they are always (but not all queries) lacking some information about CPU cost, time , etc.

Here is the ouput for the 12 queries I have:

EXPLAIN PLAN FOR SELECT l_orderkey, l_linenumber, l_extendedprice FROM lineitem WHERE l_extendedprice < 1000; 

Explained.

So, the info

is missing in some plans.

Is this normal? If not, what's the problem and how can I handle it?

Please, I'm freaking out!

I don't know you but me I am unable to read lines that I have to horizontally scroll 8 times
and I am unable to read plans with fold lines and break into 4 lines groups.

Repost in a readable way. Remove what is useless.
I don't understand that someone is able to post such a crap.

Michel

How did you find this? In fact, there are 12 EXPLAIN PLAN statements followed by 12 sections starting with
| Id  |
. Sometimes, 'Operation' column length differs, sometimes 'TempSpc' column is present.
Just curious, which tool did you use to get this?

Perhaps if you change the following sqlplus settings before generating the PLAN_TABLE report, it will help:

Those settings do solve my problem if I do it on sqlplus console.

But if I redirect the ouput of SQLPLUS, it gives me those same errors I've reported:

As you can see, in console it shows me this : (sorry, but I can't post links yet)

but doing redirect to an output file, it gets messy. It seems something is happening at the same time.

Any idea? I've been trying many possibilities.

Thank you for your answer, at least I can get some good results looking to sqpllus comand line.

I don't know if it was because of this privileges, but after doing this:

CONN / AS SYSDBA
GRANT SELECT ON v_$session TO my_schema;
GRANT SELECT ON v_$sql TO my_schema;
GRANT SELECT ON v_$sql_plan TO my_schema;
GRANT SELECT ON v_$sql_plan_statistics_all TO my_schema;

and then running sqpplus @explain_plans.sql >>out.txt

(explain plans.sql has something like this:
set lin 130 pages 999 trims on;
-- Queries C e D
EXPLAIN PLAN FOR SELECT l_orderkey, l_linenumber, l_extendedprice FROM lineitem WHERE l_extendedprice < 1000;
select * from table(dbms_xplan.display);
EXPLAIN PLAN FOR SELECT l_orderkey, l_linenumber, l_extendedprice FROM lineitem WHERE l_extendedprice < 100000;
select * from table(dbms_xplan.display);
-- .... and so on


it does write the plans in the correct way.

Thank you for the advice. I'll try to be more careful from now on.

Here is the requested output:

SELECT * from v$version;
