SQL query with different plans
Hi,
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
I cannot paste the query plan due to company policies. I can see issue with the query plan, where it is doing partition range scan (with hash join) on one environment due to which it has full table scan, on and nested loop on the second environment with Index range which is fast as compared to partition range scan.
I have checked the stats,looks updated.
Any thoughts,...
How, exactly, did you check the statistics? Did you just check when they were generated? Or did you check whether they were actually (more or less) the same?
Is it an issue with bind variable peeking?
Are there optimizer-related parameters that are different either for the databases or for different systems?
Have you looked at a 10053 trace to see how the slower system is evaluating the faster plan?
Unfortunately, without more information, it's going to be nearly impossible for us to help you narrow down the problem. We can speculate about things that might cause one environment to generate a different plan but we're blind to the details that would help us figure out which factors are actually influencing your particular systems.

Single SQl Query with different where conditions
Experts,
I have a requirement to design a report. Here are the details
I have Report table layout
Profit center Gross sales (This Year) Gross Sales (Last Year) % change Year of Year
The Report has a selection of entering the Start Date.
I have a single table in oracle which has profit center and Gross Sales Values on daily basis.
I want to write a single sql query to calculate both Gross Sales current year and Gross Sales Last Year. I can calculate Gross Sales Current Year by putting the where condition for start date = Current Year Date which i pass through report. I want to calculate the Gross Sales Last Year in the Same query by putting the different where condition i.e start date = Last Year date based on the date input.
I dont know how to put two where conditions in single query for two different columns.
Any help will be appreciated.
Thanks in advance
Regards
Santoshinstead of changing your where clause couldn't you just determine the yearly totals from your table and then use the lag statement to get last years total?
something like this?
I just made up 10,000 days worth of sales and called it fake table it is supposed to represent a variant of the table you were describing as your base table.
with fake_table as
( select trunc(sysdate + level) the_day,
level daily_gross_sales
from dual
connect by level < 10001
select yr, year_gross_sale, lag(year_gross_sale) over (order by yr) prev_year_gross_sale,
(year_gross_sale - lag(year_gross_sale) over (order by yr))/year_gross_sale * 100 percent_change
from
(select distinct yr, year_gross_sale from
select the_day,
daily_gross_sales,
extract(year from the_day) yr,
extract(year from add_months(the_day,12)) next_yr,
sum(daily_gross_sales) over (partition by extract(year from the_day)) year_gross_sale
from fake_table
order by yr

SQL query with Bind variable with slower execution plan
I have a 'normal' sql select-insert statement (not using bind variable) and it yields the following execution plan:-
Execution Plan

1 0 HASH JOIN (Cost=7 Card=1 Bytes=148)
2 1 TABLE ACCESS (BY INDEX ROWID) OF 'TABLEA' (Cost=4 Card=1 Bytes=100)
3 2 INDEX (RANGE SCAN) OF 'TABLEA_IDX_2' (NON-UNIQUE) (Cost=3 Card=1)
4 1 INDEX (FAST FULL SCAN) OF 'TABLEB_IDX_003' (NON-UNIQUE)
(Cost=2 Card=135 Bytes=6480)

I have the same query but instead running using bind variable (I test it with both oracle form and SQL*plus), it takes considerably longer with a different execution plan:-
Execution Plan
0 INSERT STATEMENT Optimizer=CHOOSE (Cost=407 Card=1 Bytes=148)
1 0 TABLE ACCESS (BY INDEX ROWID) OF 'TABLEA' (Cost=3 Card=1 Bytes=100)
2 1 NESTED LOOPS (Cost=407 Card=1 Bytes=148)
3 2 INDEX (FAST FULL SCAN) OF TABLEB_IDX_003' (NON-UNIQUE) (Cost=2 Card=135 Bytes=6480)
4 2 INDEX (RANGE SCAN) OF 'TABLEA_IDX_2' (NON-UNIQUE) (Cost=2 Card=1)

3 SQL*Net roundtrips to/from client
1 sorts (memory)
0 sorts (disk)
55 rows processed
TABLEA has around 3million record while TABLEB has 300 records. Is there anyway I can improve the speed of the sql query with bind variable? I have DBA Access to the database
Regards
IvanMany thanks for your reply.
I have run the statistic already for the both tableA and tableB as well all the indexes associated with both table (using dbms_stats, I am on 9i db ) but not the indexed columns.
for table I use:-
begin
dbms_stats.gather_table_stats(ownname=> 'IVAN', tabname=> 'TABLEA', partname=> NULL);
end;
for index I use:-
begin
dbms_stats.gather_index_stats(ownname=> 'IVAN', indname=> 'TABLEB_IDX_003', partname=> NULL);
end;
Is it possible to show me a sample of how to collect statisc for INDEX columns stats?

Use plan from stored_outlines from query with different syntax?
Hello,
I'd like to know is there any ability to use via stored_outlines plan from query with different syntax?
Database version - 11.1.06
If yes, maybe you'll take a look at steps (based on Metalink 726802.1), what I tried to do to make it work (with no success):
alter session set create_stored_outlines=good;
run good query
create private outline good from SYS_OUTLINE_0... -< GOOD
alter session set create_stored_outlines=bad;
run bad query
create private outline good from SYS_OUTLINE_0... -< BAD
update ol$ set sql_text, textlen, signature, hash_value, hash_value2 from BAD to GOOD records
leave ol$hintcount for GOOD untouched
delete ol$ where ol_name='BAD';
delete ol$hints where ol_name='BAD';
delete ol$nodes where ol_name='BAD';
execute dbms_outln_edit.refresh_private_outline('GOOD');
alter session set sql_trace=true;
alter session set use_private_outlines=true;
run bad query
examine trace file and find that it use execution plan different from both bad and good queries
PS: Originally bad query is posted already Re: Poor performance while join of 2 comprehensive large views and small table
PPS: Also I review thread CBO not picking correct indexes or doing Full Scans
Thanks,
Sergiy
Edited by: kiberpress on Sep 30, 2009 6:59 AMA query with different syntax would result in a different hash value.
Stored outlines work based on hash value.
Your question is probably answered now.

Same query with different explain plans
Hi All,
I have one of the select query with different explain plans on two separate env, the query fetches the correct index on test env whereas on prod it's not fetching the same index.
The structure, indices, no. of rows are similar in CRMINFO table with up-to-date statistics.
Env Details :
OS - Sun Solaris 5.10
DB - 10.2.0.4
Init param:
Optimizer_mode = ALL_ROWS
optimizer_dynamic_sampling integer 5
optimizer_features_enable string 10.2.0.4
optimizer_index_caching integer 90
optimizer_index_cost_adj integer 30
Query :*
SELECT COUNT (*)
FROM CRMINFO
WHERE RETAILER = :1
AND STATUS = 20
AND EXC = :1
AND SUBNO IS NULL
Expain Plan (TST):
SELECT STATEMENT ALL_ROWSCost: 916 Bytes: 19 Cardinality: 1
3 SORT AGGREGATE Bytes: 19 Cardinality: 1
2 TABLE ACCESS BY INDEX ROWID TABLE TST.CRMINFO Cost: 916 Bytes: 16,663 Cardinality: 877
1 INDEX RANGE SCAN INDEX TST.CRMINFO_X1 Cost: 42 Cardinality: 12,549
Index (TST):
CRMINFO_X1(EXC, RETAILER, STATUS)
Explain Plan (PROD):
SELECT STATEMENT ALL_ROWSCost: 1,832 Bytes: 19 Cardinality: 1
3 SORT AGGREGATE Bytes: 19 Cardinality: 1
2 TABLE ACCESS BY INDEX ROWID TABLE PROD.CRMINFO Cost: 1,832 Bytes: 2,052 Cardinality: 108
1 INDEX RANGE SCAN INDEX PROD.CRMINFO_X2 Cost: 117 Cardinality: 42,519
Index (PROD):
CRMINFO_X2 (RETAILER)
How does Oracle calculates the cost and decides which index it should fetch ? Why it didn't choose the same index as of test env? How should i approach and which domains i need to dig-in to find the cause?
I did try playing with the above mentioned init parameters but it didn't help at all.
Thanks.

Hmm, my worry is how do i force oracle to grap the proper index on prod i.e (CRMINFO_X1). I certainly believe it's a bad approach on adding a hint in the select statement and to force oralce to fetch that index.Why do you believe that, the index you mention is the "proper" index versus what Oracle is choosing? Can you prove with hinting that the "proper" index results in a faster and more efficient execution plan? If it does, then the next place I would look at is the statistics for the tables and columns of interest. From here you could try and estimate why Oracle thinks the other index is better. Another option is to run a 10053 (CBO) trace and see why Oracle thinks it is better.
I would not support a hint in a production environment, except in the most extreme cases. Usually the CBO makes the right choice, but it only can if the statistics match the distribution of data.
Refreshing the data may help me simulating the issue on TST but it wouldn't help me to understand why on prod it uses CRMINFO_X2 instead of CRMINFO_X1 which has all the three columns in the Where clause of the query.It would help because it's a test environment and you wouldn't have to do any queries directly on your production system to achieve the same results.
>
A bad thought here :( , if i create a new index by changing the column positioning say like ( RETAILER, STATUS , EXC) instead of (EXC, RETAILER, STATUS) will oracle fetch it ? or would it help in reducing the cost and cardinatlity of the select query.It's not that easy. There is a lot that goes into the cost calculation, some of that is known (through the great work by Jonathan Lewis and Richard Foote), and some of that is purely internal to Oracle. If you are more interested in the internals Cost-Based Oracle Fundamentals by Jonathan Lewis is a great book.

Simple spatial query with different SRID
Can anyone help me with just a real simple spatial query with different SRID.
Here is the error i get when i perform the query:
AND SDO_RELATE(A.geometrie_point, B.GEOMETRIE_POLYGONE, 'mask=anyinteract querytype=WINDOW') = 'TRUE'
ERROR at line 4:
ORA-00604: error occurred at recursive SQL level 1

ORA-06512: at line 4Hi,
I am using 8.1.7.2 and i have the lattest spatial patch.
From the start i had different SRID. The only thing i changed was the bounds of the coordinate system.
I reset my bounds of the coordinate system with SRID 8307 to -180,
180 in X (longitude), and -90,90 in Y (latitude) to see if the query window geometry
(geom2) will be transformed to the coordinate system of the layer geometries (geom1)
Her is the content of the user_sdo_geom_metadata :
GIS_PCP GEOMETRIE_POINT
SDO_DIM_ARRAY(SDO_DIM_ELEMENT('X', -5800000, 3600000, .00000005), SDO_DIM_ELEMENT('Y', 3516000, 6000000, .00000005))

8307
Here is my query :
select /*+ ordered */ A.no_point
from gis_pcp A, gis_test B
WHERE SDO_RELATE(A.geometrie_POINT, B.GEOMETRIE_POLYGONE, 'mask=anyinteract querytype=WINDOW') = 'TRUE';
Here is my result :
WHERE SDO_RELATE(A.geometrie_POINT, B.GEOMETRIE_POLYGONE, 'mask=anyinteract querytype=WINDOW') = 'TRUE'

If i change the bounds of GIS_TEST to the exact bouns of GIS_PCP then i dont have the error message above and i have correct results. Do i have the adjust the bounds of every layer to fit the biggest bound? -
SQL query with JSP and WML-parameters
Hey,
Could you help me?
I'm trying to do the following. WML deck card 1 send parameter to same WML deck's card help. I try to read the parameter with JSP in card help by putting the parameter to SQL query, but it doesn't work. I can read the parameter with WML in card help. I can also print the value of the parameter with JSP if I generate WML with JSP.
/*parameter sending from card 1 to card help*/
out.println("<go href='#helpcard'>");
out.println("<setvar name='valittukurssi' value='$(valittukurssi)'/>");
/*parameter read with WML in card help */
<p>Valitse kurssi.
$valittukurssi</p>
/'parameter read with JSP by generating WML with JSP*/
out.println("<p>$valittukurssi</p>");
/* SQL query with JSP */
ResultSet uudettulokset = uusilause.executeQuery("select * from kurssi where lyhenne='$valittukurssi'");
Thanks,
RampeYou're problem is easy to fix. You're confusing WML variables with JSP variables. See below:
>
/*parameter sending from card 1 to card help*/
out.println("<go href='#helpcard'>");
out.println("<setvar name='valittukurssi'
value='$(valittukurssi)'/>");
Above you set a var that will work on the phone, not in JSP.
/*parameter read with WML in card help */
<p>Valitse kurssi.
$valittukurssi</p>
Yes the above does display the parameter, because it is a client side WML var, but you cannot use this variable in the JSP code (that's why your SWL fails).
/'parameter read with JSP by generating WML with
JSP*/
out.println("<p>$valittukurssi</p>");Here's you're problem, the above line is EXACTLY the same as the one before it. When the container parses through this JSP code it translates the above line to:
<p>$valittukurssi</p> on the WML page and the CLIENT uses it's local variable to display it.
What you need and want is to have a variable that can be used in JSP code and output to your WML page. Here's how it's done:
out.println("<go href='#helpcard'>");
String some_name = "valittukurssi";
out.println("<setvar name='"+some_name+"'
value='$("+some_name+")'/>");
//note that you may have to escape the ( and ) with a \
//so we displayed the variable above into the WML page, now we can use it in the SQL query:
/* SQL query with JSP */
ResultSet uudettulokset =
uusilause.executeQuery("select * from kurssi where
lyhenne='"+some_name+"'");//the end of the command is: " ' " ) ;

Extract Sql Query with Actual Parameters from Report
Hi
I am able to extract query from Crystal Report using the following code :
ReportDocument.ReportClientDocument.RowSetController.GetSqlStatement(new GroupPath, out tmp);
But the sql query retrieve comes in the following format :
select name , trans_code, account_code from command_query.accounts
where account_code = {?Command_query_Prompt0} and effective_date < '{?Command_query_prompt1 }'
The parameters which I m using in the reports are :
Account_Code and Effective_Date .
Why does my extracted sql translates it into {?Command_query_Prompt0} and '{?Command_query_prompt1 }' .
Is there any way to map this to the actual parameter values ?
OR
Can we extract the query after assigning the values ?
Any help is appreciated ...
Thanks
Sanchethi,
You can create nested sql query with conditional parameters,
For example
Select Code From OITT Where Code IN (Select ItemCode From OITM
Where ItemName LIKE '[%0]' + '%%')

Hosting company does not support SQL query with OUTFILE clause
From my mysql database, I want to allow the user to run a query and produce a csv / text file of our membership database. Unfortunately, I just found out my hosting company does not support the SQL query with OUTFILE clause for MySQL database.
Are there any other options available to produce a file besides me running the query in phpadmin and making the file available to users.
Thanks. GeorgeMaybe this external Export Mysql data to CSV - PHP tutorial will be of help

Lync 2013 sql mirroring with different doamin sql server.
Hi,
can I create lync BE sql mirroring with different domain sql server with one AD forest?
Thanks.Hi,
You can note the sentence “Using Topology Builder or cmdlets to set up and remove SQL mirroring is supported only when the primary, mirror, and witness (if desired) servers all belong to the same domain. If you want to set up SQL mirroring among servers
in different domains, see your SQL Server documentation.” In the link below:
http://technet.microsoft.com/en-us/library/jj204992.aspx
So I think in Lync server if you use Topology Builder or cmdlets to set up and remove SQL mirroring only if when the primary, mirror, and witness (if desired) servers all belong to the same domain. If you want to set up SQL mirroring among servers in different
domains you may do some steps on SQL server and you can also post a case on SQL forum, thank you for your understanding.

Same query with different execution plan
Hello All,
I wonder why does sql server create different execution plan for these below queries ?
Thanks.You can look at the expected query plan. Either visually in SSMS, or alternatively, you can run the query after the instruction SET SHOWPLAN_TEXT ON.
The Optimizer is the component of SQL Server that determines how the query is executed. It is cost based. It will assess different execution plans, estimate the cost of each of them and then select the cheapest. In this context, cheapest means the one with
the shortest runtime.
In your particular case, the estimation for the second query is, that scanning just a small part of the nonclustered index and then looking up the table data of the qualifying rows is the cheapest approach, because the estimated number of qualifying rows
is low.
In the first query, it estimated that looking up the many qualifying rows there would be too expensive, and that it would be cheaper to simply scan the entire clustered index, and simply filter out all unwanted rows. Note that the clustered index includes
the actual table data.
