Pagination query help needed for large table - force a different index
I'm using a slight modification of the pagination query from over at Ask Tom's: [http://www.oracle.com/technology/oramag/oracle/07-jan/o17asktom.html]
Mine looks like this when fetching the first 100 rows of all members with last name Smith, ordered by join date:
SELECT members.*
FROM members,
SELECT RID, rownum rnum
FROM
SELECT rowid as RID
FROM members
WHERE last_name = 'Smith'
ORDER BY joindate
WHERE rownum <= 100
WHERE rnum >= 1
and RID = members.rowidThe difference between this and the one at Ask Tom's is that my innermost query just returns the ROWID. Then in the outermost query we join the ROWIDs returned to the members table, after we have pruned the ROWIDs down to only the chunk of 100 we want. This makes it MUCH faster (verifiably) on our large tables, as it is able to use the index on the innermost query (well... read on).
The problem I have is this:
SELECT rowid as RID
FROM members
WHERE last_name = 'Smith'
ORDER BY joindateThis will use the index for the predicate column (last_name) instead of the unique index I have defined for the joindate column (joindate, sequence). (Verifiable with explain plan). It is much slower this way on a large table. So I can hint it using either of the following methods:
SELECT /*+ index(members, joindate_idx) */ rowid as RID
FROM members
WHERE last_name = 'Smith'
ORDER BY joindate
SELECT /*+ first_rows(100) */ rowid as RID
FROM members
WHERE last_name = 'Smith'
ORDER BY joindateEither way, it now uses the index of the ORDER BY column (joindate_idx), so now it is much faster as it does not have to do a sort (remember, VERY large table, millions of records). So that seems good. But now, on my outermost query, I join the rowid with the meaningful columns of data from the members table, as commented below:
SELECT members.* -- Select all data from members table
FROM members, -- members table added to FROM clause
SELECT RID, rownum rnum
FROM
SELECT /*+ index(members, joindate_idx) */ rowid as RID -- Hint is ignored now that I am joining in the outer query
FROM members
WHERE last_name = 'Smith'
ORDER BY joindate
WHERE rownum <= 100
WHERE rnum >= 1
and RID = members.rowid -- Merge the members table on the rowid we pulled from the inner queriesOnce I do this join, it goes back to using the predicate index (last_name) and has to perform the sort once it finds all matching values (which can be a lot in this table, there is high cardinality on some columns).
So my question is, in the full query above, is there any way I can get it to use the ORDER BY column for indexing to prevent it from having to do a sort? The join is what causes it to revert back to using the predicate index, even with hints. Remove the join and just return the ROWIDs for those 100 records and it flies, even on 10 million records.
It'd be great if there was some generic hint that could accomplish this, such that if we change the table/columns/indexes, we don't need to change the hint (the FIRST_ROWS hint is a good example of this, while the INDEX hint is the opposite), but any help would be appreciated. I can provide explain plans for any of the above if needed.

Lakmal (and OP),
Not sure what advantage you are trying to show here. But considering that we are talking about pagination query here and order of records is important, your 2 queries will not always generate output in same order. Here is the test case:

SQL> set autotrace off
SQL> spool offAs you will see, the join query here has to have an ORDER BY clause at the end to ensure that records are correctly sorted. You can not rely on optimizer choosing NESTED LOOP join method and, as above example shows, when optimizer chooses HASH JOIN, oracle is free to return rows in no particular order.
The query that does not involve join always returns rows in the desired order. Adding an ORDER BY does add a step in the plan for the query using join but does not affect the other query. -
Update sql help needed for hierarchy table

Hi ,
I have a function which returns nested table as result .The nested table can sometimes be null.So when i reference the first and last value for a loop, when table is null , then i am getting numeric value error .So i added a check on the nested table as below
if n_table is empty then
exit;
end if;
for i in n_table.first ..n_table.last
loop
select count(1) into_count

help needed for writing query
i have the following tables(with data) as mentioned below
FK*-foregin key (SUBJECTS)
FK**-foregin key (COMBINATION)
1)SUBJECTS(table name)
SUB_ID(NUMBER) SUB_CODE(VARCHAR2) SUB_NAME (VARCHAR2)
2 02 Computer Science
3 03 Physics
4 04 Chemistry
5 05 Mathematics
7 07 Commerce
8 08 Computer Applications
9 09 Biology
2)COMBINATION
COMB_ID(NUMBER) COMB_NAME(VARCHAR2) SUB_ID1(NUMBER(FK*)) SUB_ID2(NUMBER(FK*)) SUB_ID3(NUMBER(FK*)) SUBJ_ID4(NUMBER(FK*))
383 S1 9 4 2 3
384 S2 4 2 5 3
---------I actually designed the ABOVE table also like this
3) a)COMBINATION
COMB_ID(NUMBER) COMB_NAME(VARCHAR2)
383 S1
384 S2
b)COMBINATION_DET
COMBDET_ID(NUMBER) COMB_ID(FK**) SUB_ID(FK*)
1 383 9
2 383 4
3 383 2
4 383 3
5 384 4
6 384 2
7 384 5
8 384 3
Business rule: a combination consists of a maximum of 4 subjects (must contain)
and the user is less relevant to a COMB_NAME(name of combinations) but user need
the subjects contained in combinations
i need the following output
COMB_ID COMB_NAME SUBJECT1 SUBJECT2 SUBJECT3 SUBJECT4
383 S1 Biology Chemistry Computer Science Physics
384 S2 Chemistry Computer Science Mathematics Physics
or even this is enough(what i actually needed)
COMB_ID subjects
383 Biology,Chemistry,Computer Science,Physics
384 Chemistry,Computer Science,Mathematics,Physics
you can use any of the COMBINATION table(either (2) or (3))
and i want to know
1)which design is good in this case
(i think SUB_ID1,SUB_ID2,SUB_ID3,SUB_ID4 is not a
good method to link with same table but if 4 subjects only(and must) comes
detail table is not neccessary )
now i am achieving the result by program-coding in C# after getting the rows from oracle
i am using oracle 9i (also ODP.NET)
i want to know how can i get the result in the stored procedure itsef.
2)how it could be designed in any other way.
any help/suggestion is welcome
thanks for your time --PradeeshWell I forgot the table-alias, here now with:
SELECT C.COMB_ID
, C.COMB_NAME
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID1) AS SUBJECT_NAME1
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID2) AS SUBJECT_NAME2
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID3) AS SUBJECT_NAME3
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID4) AS SUBJECT_NAME4
FROM COMBINATION C;
As you need exactly 4 subjects, the columns-solution is just fine I would say. -
Color management help needed for adobe CS5 and Epson printer 1400-Prints coming out too dark with re
Color management help needed for adobe CS5 and Epson printer 1400-Prints coming out too dark with reddish cast and loss of detail
System: Windows 7
Adobe CS5
Printer: Epson Stylus Photo 1400
Paper: Inkjet matte presentation paper with slight luster
Installed latest patch for Adobe CS5
Epson driver up to date
After reading solutions online and trying them for my settings for 2 days I am still unable to print what I am seeing on my screen in Adobe CS5. I calibrated my monitor, but am not sure once calibration is saved if I somehow use this setting in Photoshop’s color management.
The files I am printing are photographs of dogs with lots of detail I digitally painted with my Wacom tablet in Photoshop CS5 and then printed with Epson Stylus 1400 on inkjet paper 20lb with slight luster.
My Printed images lose a lot of the detail & come out way to dark with a reddish cast and loss of detail when I used these settings in the printing window:
Color Handling: Photoshop manages color, Color management -ICM, OFF no color adjustment.
When I change to these settings in printer window: Color Handling: Printer manages color. Color management- Color Controls, 1.8 Gamma and choose Epson Standard it prints lighter, but with reddish cast and very little detail and this is the best setting I have used so far.
Based on what I have read on line, I think the issue is mainly to do with what controls are set in the Photoshop Color Settings window and the Epson Printer preferences. I have screen images attached of these windows and would appreciate knowing what you recommend I enter for each choice.
Also I am confused as to what ICM color management system to use with this printer and CS5:
What is the best ICM to use with PS CS5 & the Epson 1400 printer? Should I use the same ICM for both?
Do I embed the ICM I choose into the new files I create?
Do I view all files in the CS5 workspace in this default ICM?
Do I set my monitor setting to the same ICM?
If new file opens in CS5 workspace and it has a different embedded profile than my workspace, do I convert it?
Do I set my printer, Monitor and PS CS5 color settings to the same ICM?
Is using the same ICM for all devices what is called a consistent workflow?
I appreciate any and all advice that can be sent my way on this complicated issue. Thank you in advance for your time and kind help.It may be possible to figure out by watching a Dr.Brown video on the subject of color printing. Adobe tv
I hope this may help............... -

How to use remote directory for external table
Hi Folks,
I have 2 Oracle 11GR2 64 bit database installed on Win 2008 server as prod1 and prod2.
I have one directory created on prod1 server as EXT_TAB_DIR using the path as D:\OrsDWtest_dir .
I want to use this directory in Prod2 server and use external table using this remote directory.
I am able to access the Prod1 directory from Prod2 machine and also i have created Network map drive as Z drive pointing to that prod1 D:\OrsDWtest_dir directory. Also i checked read and Write permissions are there . I am able to create the external table but when i try to fetch the data i m getting below error ..

ORA-29400: data cartridge error
KUP-04040: file IOMM_20121213_060736.csv in EXT_TAB_DIR not found
now my doubt is this possible ? Can we use remote directory for External table ? or is there is there any alternative way to achieve same ?
Thanks & Regards,
Vikash Jain(DBA)could you confirm the name and the existence of this file "IOMM_20121213_060736.csv" ?

How can i avoid that kind of special symbols while creating the External Table.
I tried with the TRIM command also with External Table Scripts but it doesn't works.

Need help in Creating External Tables
Hi All,
I have a flat file containing numberic data, CLOB data, and also date columns data. I have to load this flat file data into staging server table using External tables. I have to write a stored procedure in such way creating exteranl tables dynamically. My question or need help from you people is that how to define the external table to load the CLOB data from flat file.
Thanks,
SankarThe LOCATION clause of an external table specifies the file or files to be read when the table is queried. You can change it to refer to different files without dropping and recreating the table and invalidating all dependent code.
Regarding DBMS_SQL, yes you can do it the hard way if you prefer.
Good point about CLOB columns in external tables. Quite possibly they are not supported, but I would have to check the manuals and try some examples. -

Unix permission problem for external table in oracle 10g, sun solaris
Hello All,
I'm facing a problem in accessing external table which has stumped me a bit.
What I'm looking for is to use a external table with restricted permission to Others(770) on unix.
Would appreciate if someone helps me out here.
Here are the steps:
1.create directory ext_tab_dir1 as '/home/ravi/test'
2.grant read,write on directory ext_tab_dir1 to scott
3.CREATE TABLE scott.emp_load1(employee_number CHAR(5))
ORGANIZATION EXTERNAL (
type oracle_loader
default directory ext_tab_dir1
access parameters (
records delimited by newline
fields terminated by ' '
optionally enclosed by '"'
missing field values are null
location ('info.dat')
Now I have added unix user oracle to unix group myDbGroup and provided myDbGroup read/write/exec permission on directory /home/ravi/test.
info.dat has been placed in /home/ravi/test.
#pwd
/home/ravi
#ls -l
drwxrwx--- 2 ravi myDbGroup 512 Mar 7 17:35 test
I have manually logged in as user oracle and successfully created a sample file in /home/ravi/test.
-rwxrwx--- 1 ravi myDbGroup 13 Mar 7 17:33 info.dat
-rw-r--r-- 1 oracle oinstall 0 Mar 7 18:05 sampleFile
I then connect to the db using sqlplus as ravi and do a
#select * from scott.emp_load1
I get the following error
ERROR at line 1:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-04063: unable to open log file emp_load1_18567.log
OS error Permission denied
ORA-06512: at "SYS.ORACLE_LOADER", line 19
After this, I gave full permission to /home/ravi/test
drwxrwxrwx 2 ravi myDbGroup 512 Mar 7 17:35 test
#select * from scott.emp_load1
And this was successful.
It created a log file in /home/ravi/test
-rwxrwx--- 1 ravi myDbGroup 13 Mar 7 17:33 info.dat
-rw-r--r-- 1 oracle oinstall 0 Mar 7 18:05 sampleFile
-rw-r--r-- 1 oracle oinstall 0 Mar 7 18:05 emp_load1_18567.log
Now what stumped me is the owner and group owner of the file emp_load1_18567.log.
It is same as the sampleFile which I created manually!!
From this it can be deducted oracle is not using user id oracle while reading/writing to the unix directory but somehow assigning user id oracle as owner to the log file at the end.
If someone has encountered this problem earlier or has some info about this...pls share.
Regards,
RavinandanThanks for the reply.
I have earlier checked this with NOLOGFILE option.
But no luck.
I would like to add one more detail(which I missed earlier) about the problem.
If I give 750 access to /home/ravi(That is read/exec to Group and none perm to Others),
I will get the same error(KUP-04063: unable to open log file emp_load1_18567.log).
This obviously means oracle is not even able to access the directory(Although unix user oracle has access via the group perms).
