Add ORDER BY to make ANY query faster
Yes it’s SCBT day here in Perth!
SCBT = Silly Click Bait Title 
This post is just a cautionary tale that it is easy to get caught up judging SQL performance solely on a few metrics rather than taking a more common sense approach of assessing performance based on the true requirements of the relevant component of the application. I say “true requirements” because it may vary depending on what is important to the application for a particular component.
For the majority of the time, response time is most probably the thing you will care about most. Certainly for customer-facing components of an application, response time is likely to be the dominant factor in defining application “success”. But it does not necessarily always need to be response time. You might have a SQL statement that gets executed millions (or billions) of times, and hence perhaps parse time CPU or overall latching activity might be a critical factor.
My point is this: Not all SQL statements can be simply judged on a rule of “less consistent gets = a better SQL”. Here’s an example that came up on AskTOM recently, hence the click bait title. I’ll start with 100 copies of DBA_OBJECTS to be my source table.
SQL> create table t pctfree 0
2 as select owner, object_id, subobject_name
3 from dba_objects,
4 ( select 1 from dual connect by level <= 100 );
Table created.
SQL>
SQL> exec dbms_stats.gather_table_stats('','t');
PL/SQL procedure successfully completed.
We’ll connect to SQL Plus and just run a simple SELECT to retrieve all of the rows.
SQL> set autotrace traceonly statistics
SQL> select * from t;
8350600 rows selected.
Statistics
------------------------------------------------------
13 recursive calls
17 db block gets
849818 consistent gets
1 physical reads
3024 redo size
294152578 bytes sent via SQL*Net to client
9186257 bytes received via SQL*Net from client
835061 SQL*Net roundtrips to/from client
0 sorts (memory)
0 sorts (disk)
8350600 rows processed
Wow…that’s a lot of consistent gets. Here’s my simple solution to reduce that. We’ll just an ORDER BY clause!
SQL> select * from t order by object_id;
8350600 rows selected.
Statistics
-------------------------------------------------------
170 recursive calls
4 db block gets
16469 consistent gets
21597 physical reads
0 redo size
201757283 bytes sent via SQL*Net to client
9186257 bytes received via SQL*Net from client
835061 SQL*Net roundtrips to/from client
0 sorts (memory)
1 sorts (disk)
8350600 rows processed
Woo hoo! Look how much I’ve dropped the consistent gets. Time for me to scream from the roof tops “I am a SQL tuning genius!”
In reality, I don’t need an ORDER BY to improve the “consistent gets” number from the SELECT statement. One of the governing factors for how many consistent gets we will need to do is the fetch size, and my original execution was performed with a fetch size (arraysize in SQL Plus) of just 10. Let’s bump that up and re-run the query:
SQL> set arraysize 1000
SQL> select * from t;
8350600 rows selected.
Statistics
------------------------------------------------------
0 recursive calls
0 db block gets
24805 consistent gets
0 physical reads
0 redo size
133771032 bytes sent via SQL*Net to client
92458 bytes received via SQL*Net from client
8352 SQL*Net roundtrips to/from client
0 sorts (memory)
0 sorts (disk)
8350600 rows processed
Voila! An easy “fix” to consistent gets. In reality, don’t forget that consistent gets is just one piece of the performance performance puzzle. If I throw in some response time metrics for the above queries, then (as an application user) I know which query I would prefer to have running!
SQL> set autotrace off
SQL> set timing on
SQL> set feedback only
SQL> select * from t;
8350600 rows selected.
Elapsed: 00:00:02.08
SQL> select * from t order by object_id;
8350600 rows selected.
Elapsed: 00:00:09.70
SQL>
So, click bait titles aside, make sure you don’t get too carried away just focussing on particular metrics (eg consistent gets) when assessing and tuning the performance of your SQL statements.
Interval versus Range partitions
One of the nice things about partitioning in the database is that partition pruning can quickly eliminate the requirement to read large amounts of data when the partitioning key(s) are appropriately provided in your queries (and DML). This also extends to queries where the values provided do not map to any partitions.
Here’s a simple example of a range partitioned table which only cover the values from (less than) 1 to a ceiling of 6.
SQL> create table t
2 partition by range(x)
3 ( partition p0 values less than (1),
4 partition p1 values less than (2),
5 partition p2 values less than (3),
6 partition p3 values less than (4),
7 partition p4 values less than (5),
8 partition p5 values less than (6)
9 )
10 as
11 select rownum x from dual connect by level <= 5;
Table created.
Let’s see what happens when I run a query for a value that by definition cannot possibly exist in the table.
SQL> select * from t where x = 1235;
no rows selected
SQL> select * from table(dbms_xplan.display_cursor);
PLAN_TABLE_OUTPUT
-----------------------------------------------------------------------------------------------
SQL_ID auv890vfz95vu, child number 0
-------------------------------------
select * from t where x = 1235
Plan hash value: 4294331813
----------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop |
----------------------------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | | | 2 (100)| | | |
| 1 | PARTITION RANGE EMPTY| | 1 | 3 | 2 (0)| 00:00:01 |INVALID|INVALID|
|* 2 | TABLE ACCESS FULL | T | 1 | 3 | 2 (0)| 00:00:01 |INVALID|INVALID|
----------------------------------------------------------------------------------------------
Predicate Information (identified by operation id):
---------------------------------------------------
2 - filter("X"=1235)
That’s pretty cool. You can see that terms “EMPTY” and “INVALID” in the plan. The database knows from the dictionary definitions of the partitions that there is no possible data for X=1235 and hence the table partitions do not need to be accessed at all.
I’ll now repeat the example, but using an INTERVAL partitioned table. I only need to define the first partition, but since the interval size is 1, it will create partitions identical to the range example above.
SQL> create table t
2 partition by range(x) interval(1)
3 ( partition p0 values less than (1) )
4 as
5 select rownum x from dual connect by level <= 5;
Table created.
SQL>
SQL> select * from t where x = 1235;
no rows selected
SQL> select * from table(dbms_xplan.display_cursor);
PLAN_TABLE_OUTPUT
-----------------------------------------------------------------------------------------------
SQL_ID auv890vfz95vu, child number 0
-------------------------------------
select * from t where x = 1235
Plan hash value: 2931986080
-----------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Pstart| Pstop |
-----------------------------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | | | 6 (100)| | | |
| 1 | PARTITION RANGE SINGLE| | 1 | 3 | 6 (0)| 00:00:01 | 1236 | 1236 |
|* 2 | TABLE ACCESS FULL | T | 1 | 3 | 6 (0)| 00:00:01 | 1236 | 1236 |
-----------------------------------------------------------------------------------------------
Predicate Information (identified by operation id):
---------------------------------------------------
2 - filter("X"=1235)
Notice that the results here are slightly different. Even though no partition exists for X=1235, for an interval partitioned table the optimizer suggests that it will scan the (fictitious) partition 1236. Is this a bug?
To explain this, I like to think of interval partitioning as an extension of the deferred segment implementation we already have in the database. The database can defer creating a physical segment when a table (or table partition) is created. The segment only needs to come into existence when the first row is created for that table. The way I interpret interval partitioning, is that it takes deferring segments to another level, namely deferring the dictionary metadata as well until it is needed. You can think of interval partition table DDL as creating all of the partitions in the table immediately (ie, they all exist) but the dictionary metadata to support them is deferred until required. Hence partition 1236 in the example does indeed exist – it is just that we have not yet created the dictionary entries for it yet – we won’t do so until the first row is created.
Based on this concept, you can still see the concept of EMPTY/INVALID partitions for a query on an interval partitioned table if you nominate a value that would yield a non-existent partition. You may be thinking “How can we have a non-existent partition for an interval partitioned table?”. Don’t forget that there is an upper limit on the number of partitions you can have for any partitioned table, so all I need do is nominate a value for X that would yield a partition above that upper bound.

FIRST_ROWS_10 CBO Is Hopeless, It’s Using The Wrong Index !! (Weeping Wall)
There’s an organisation I had been dealing with on and off over the years who were having all sorts of issues with their Siebel System and who were totally convinced their performance issues were due directly to being forced to use the FIRST_ROWS_10 optimizer. I’ve attempted on a number of occasions to explain that their […]

The Openworld Mega-Download!
If you are sad and pathetic enthusiastic and interested in content like me, once a large conference like OpenWorld is over, I like to have the content (slides etc ) from not just the sessions I attended, but all of the sessions I could not attend. In fact, I typically would like to have any and all available content, because that is probably the next best thing to attending the conference.
In particular, now that many of the sessions are streamed and/or capture for on-demand replay, either on the OpenWorld site directly, or via the Oracle Developers Youtube channel, the slides can then be viewed along with the presentation that drove them.
Unfortunately, the session catalog does not really cater to that need. It is very much focussed along a mantra of “pick a single session”, and then you can download the content for just that session.
If you want lots of content, then no-one wants to click and expand and download, click and expand and download, click and expand and download, click and expand and download etc etc.
So the full stack developer is back with a vengeance 
to give you the full suite of content easily available at your fingertips!
I swept through the JSON and extracted all of the files I could find.
So here is a script that will use CURL to download all of the content, or you can pick and choose from the list below.
Enjoy!

Join Cardinality – 5
So far in this series I’ve written about the way that the optimizer estimates cardinality for an equijoin where one end of the join has a frequency histogram and the other end has a histogram of type:
It’s now time to look at a join where the other end has a height-balanced histogram. Arguably it’s not sensible to spend time writing about this since you shouldn’t be creating them in 12c (depending, instead, on the hybrid histogram that goes with the auto_sample_size), and the arithmetic is different in 11g. However, there still seem to be plenty of people running 12c but not using the auto_sample_size and that means they could be generating some height-balanced histograms – so let’s generate some data and see what happens.

As in earlier examples I’ve created some empty tables, then inserted randomly generated data (after calling the dbms_random.seed(0) function to make the data reproducible). Then I’ve gathered stats, knowing that there will be 22 distinct values in t2 so forcing a height-balanced histogram of 20 buckets to appear.
When we try to calculate the join cardinality we’re going to need various details from the histogram information, such as bucket sizes, number of distinct values, and so on, so in the next few queries to display the histogram information I’ve captured a few values into SQL*Plus variables. Here’s the basic information about the histograms on the join columns t1.j1 and t2.j2:
column num_distinct new_value m_t2_distinct
column num_rows new_value m_t2_rows
column num_buckets new_value m_t2_buckets

As you can see, there is a frequency histogram on t1 reporting a cumulative total of 100 rows; and the histogram on t2 is a height-balanced histogram of 20 buckets, showing 21, 24, 25, 26, 27 and 28 as popular values with 2,2,2,2,3 and 2 endpoints (i.e. buckets) respectively. You’ll also note that the t2 histogram has 21 rows with row/bucket 0 showing us the minimum value in the column and letting us know that bucket 1 is not exclusively full of the value 14. (If 14 had been the minimum value for the column as well as an end point Oracle would not have created a bucket 0 – that may be a little detail that isn’t well-known – and will be the subject of a little follow-up blog note.)
Let’s modify the code to join the two sets of hisogram data on data value – using a full outer join so we don’t lose any data but restricting ourselves to values where the histograms overlap. We’re going to follow the idea we’ve developed in earlier postings and multiply frequencies together to derive a join frequency, so we’ll start with a simple full outer join and assume that when we find a real match value we should behave as if the height-balanced buckets (t2) where the bucket count is 2 or greater represent completely full buckets and are popular values..
I’ve also included in this query (because it had a convenient full outer join) a column selection that counts how many rows there are in t1 with values that fall inside the range of the t2 histogram but don’t match a popular value in t2.

We captured the bucket size (&m_bucket_size) for the t2 histogram as 40 in the earlier SQL, and we can see now that in the overlap range (which I’ve hard coded as 2 – 25) we have three buckets that identify popular values, but only one of them corresponds to a value in the frequency histogram on t1, so the Product column shows a value of 1 * 2 * 40 = 80. Unfortunately this is a long way off the prediction that the optimizer is going to make for the simple join. (Eventually we’ll see it’s 1,893 so we have a lot more rows to estimate for).
Our code so far only acounts for items that are popular in both tables. Previous experience tells us that when a popular value exists only at one end of the join predicate we need to derive a contribution to the total prediction through an “average selectivity” calculated for the other end of the join predicate. For frequency histograms we’ve seen that “half the number of the least frequently occuring value” seems to be the appropriate frequency estimate, and if we add that in we’ll get two more contributions to the total from the values 21 and 24 which appear in the height-balanced (t2) histogram as popular but don’t appear in the frequency (t1) histogram. Since the lowest frequency in t1 is 1 this would give us two contributions of 0.5 * 2 (buckets) * 40 (bucket size) viz: two contributions of 40 bringing our total to 160 – still a serious shortfall from Oracle’s prediction. So we need to work out how Oracle generates an “average frequency” for the non-popular values of t2 and then apply it to the 99 rows in t1 that haven’t yet been accounted for in the output above.
To calculate the “average selectivity” of a non-popular row in t2 I need a few numbers (some of which I’ve already acquired above). The total number of rows in the table (NR), the number of distinct values (NDV), and the number of popular values (NPV), from which we can derive the the number of distinct non-popular values and the number of rows for the non-popular values. The model that Oracle uses to derive these numbers is simply to assume that a value is popular if its frequency in the histogram is greater than one and the number of rows for that value is “frequency * bucket size”.
The first query we ran against the t2 histogram showed 6 popular values, accounting for 13 buckets of 40 rows each. We reported 22 distinct values for the column and 800 rows for the table so the optimizer assumes the non-popular values account for (22 – 6) = 16 distinct values and (800 – 13 * 40) = 280 rows. So the selectivity of non-popular values is (280/800) * (1/16) = 0.021875. This needs to be multiplied by the 99 rows in t1 which don’t match a popular value in t2 – so we now need to write some SQL to derive that number.
We could enhance our earlier full outer join and slot 0.5, 99, and 0.021875 into it as “magic” constants. Rather than do that though I’m going to write a couple of messy queries to derive the values (and the low/high range we’re interested in) so that I will be able to tweak the data later on and see if the formula still produces the right answer.

This query finds the overlap by querying the two histograms and reporting the lower high value and higher low value. It also reports the minimum frequency from the frequency histogram and divides by 2, and calculates the number of non-popular rows divided by the total number of rows and the number of distinct non-popular values. (Note that I’ve picked up the number of distinct values in t2.j2 as a substituion variable generated by one of my earlier queries.) In my full script this messy piece of code runs before the query that showed I showed earlier on that told us how well (or badly) the two histograms matched.
Finally we can use the various values we’ve picked up in a slightly more complex version of the full outer join – with a special row added through a union all to give us our the estimate:

The E-rows for the hash join operation reports 1893 – and a quick check of the 10053 trace file shows that this is 1892.500000 rounded – a perfect match for the result from my query. I’ve modified the data in various ways (notably updating the t1 table to change the value 25 (i.e. the current maximum value of j1) to other, lower, values) and the algorithm in the script seems to be sound – for 12c and 18c. I won’t be surprised, however, if someone comes up with a data pattern where the wrong estimate appears.
Don’t look back
Upgrades are a pain. With the same data set and same statistics on 11.2.0.4, running the same join query between t1 and t2, here’s the execution plan I got:

Notice that the E-rows value is different. The join cardinality algorithm seems to have changed in the upgrade from 11.2.0.4 to 12c. I haven’t quite figured out how to get to the 11g result, but I seem to get quite close most of the time by making a simple change to the final query that I used to predict the optimizer’s estimate. In the case expression that chooses between the actual t1.j1 frequency and the “average frequency” don’t choose, just use the latter:
case
when f2.frequency > 1 and f1.frequency is not null
-- then f1.frequency -- 12c
then &m_avg_t1_freq -- 11g
when f2.frequency > 1 and f1.frequency is null
then &m_avg_t1_freq
end *
As I modified the t1 row with the value 25 to hold other values this change kept producing results that were exactly 2, 2.5, or 3.0 different from the execution plan E-Rows – except in one case where the error was exactly 15.5 (which looks suspiciously like 17.5: the “average frequency in t2” minus 2). I’m not keen to spend time trying to work out exactly what’s going on but the takeaway from this change is that anyone upgrading from 11g to 12c may find that some of their queries change plans because they happen to match the type of example I’ve been working with in this post.
In some email I exchanged with Chinar Aliyev, he suggested three fix-controls that might be relevant. I’ve added these to an earlier posting I did when I first hit the anomaly a few days ago but I’ll repeat them here. I will be testing their effects at some point in the not too distant future:

But in a nutshell, it protects against of the concept of a low privileged account “asking” a higher privileged account to run something in order to get access to those higher privileges. In human terms, this is a me phoning the DBA and saying: “Hi, could you run my procedure for me?” when deep down inside the code of that procedure I’ve embedded something nasty.
The INHERIT PRIVILEGES is a new privilege that can be used to guard against such scenarios, but we had a question on AskTOM on where to find such grants. Interestingly, even though it is a privilege given on a user to a user, if you need to find where the privileges are granted, you need to look in DBA_TAB_PRIVS, and the user that is the subject of the privilege will be found in the TABLE_NAME column. Go figure
