What will be the result of this slider?
Hi all
I'm learning step, find, following the example of the net and want to know what will be the output of type v_emp_data
DECLARE
CURSOR ABC_EMP
IS
SELECT EMPNO,
ENAME,
DEPTNO,
SAL
FROM EMP;

V_sal_type TYPE TABLE IS NUMBER

LPAD (V_EMP_REC. EMPNO, 4, ' ')
|| LPAD (V_EMP_REC. ENAME, 10, ' ')
|| LPAD (V_EMP_REC. DEPTNO, 2, ' ')): =.
V_EMP_REC. SAL;
DBMS_OUTPUT. Put_line (v_emp_data. (Count);
END LOOP;
END;
/
It shows 1 to 14, that is to say no. of recordings, but how do I see the data it contains. Help, please.
Kind regards.

Hello
I would like to know if I use the SSD drive for the operating system boot and a hard drive for data. What will be the benefit of this effect,
I know that SSDS starts much more quickly and reads and writes data faster.
When I use the SSD for OS then my only wil advantage so I have faster from the OS, not more than
but the reading and writing data wil either by the hard drive so I wil not use all the benefits of the SSD, data wil be read and written by hard drive!
Am I right or wrong?

SSD benefits for most of the time of loading, and it is for all software. If you install Windows on a SSD and return to a HARD drive after a few weeks you will certainly appreciate the value of an SSD, just for the
only the loading.
While startup in Windows is the most obvious, the Windows advantage is usually a bit snappier
on an SSD.
An SSD expected to also help in many programs such as Photoshop, video editing, the processing speeds
or CAD, due to data being created during the writing of these programs.
I think the reads and writes more visible with large files.
All my programs are on the SSD, but my games are on the HARD disk.
Games to load a large number of data and will load faster on an SSD, but it's still a few seconds.
and as games use a lot of Go, it is not really profitable to keep (150 +) on an SSD.
-J' I keep most of my data, except the music (to save space) in my user folder, but haven't really
noticed a difference in speed when opening a data file, such as a Word, PDF, images, or similar
'small' files from the HARD drive.
-I wouldn't take an SSD less 120 GB. Try to run Windows on a 60GB translate toostuffing autour with management of data between the SSD and HDD. In particular, as it should be
keep 20% an SSD free to allow the two "garbage collection" and deliver a load of
cells of extra memory to extend the life of the DSS (data gets moved to empty cells when the cells die).
There is also a noticeable difference between the speeds of SATA2 and SATA 3 controller, so if your motherboard uses the SATA2 more the advantage of an SSD is not as great as with SATA3.
In addition, the new SATA3 SSD controllers are faster than those of two years ago.
SSD is a big enough topic. There are many items in the wild that may be useful.

Hello
The problem is that you to act as a Cartesian product with all the tables (you will get: S01 * S02 * S08 * S09 lines!) Is it really what you want?
I don't think...Wharton, you can do (with no Cartesian product) is:
CURSOR c_sortest_SAT_scores(p_pidm IN saturn.sortest.sortest_pidm%TYPE, p_term in saradap.saradap_term_code_entry%TYPE) IS SELECT sortest_pidm pidm, sortest_tesc_code tesc_code, sortest_test_score score FROM sortest WHERE (sortest_tesc_code, sortest_test_score) IN ( SELECT sortest_tesc_code, MAX (sortest_test_score) FROM sortest WHERE sortest_tesc_code IN ('S01', 'S02', 'S07', 'S08', 'S09') AND sortest_pidm = :p_pidm AND sortest_term_code_entry = :p_term GROUP BY sortest_tesc_code) AND sortest_pidm = :p_pidm AND sortest_term_code_entry = :p_term
However you absolutely need a Cartesian product, you can do:
WITH allrows AS (SELECT sortest_pidm pidm, sortest_tesc_code tesc_code, sortest_test_score score FROM sortest WHERE (sortest_tesc_code, sortest_test_score) IN ( SELECT sortest_tesc_code, MAX (sortest_test_score) FROM sortest WHERE sortest_tesc_code IN ('S01', 'S02', 'S07', 'S08', 'S09') AND sortest_pidm = :p_pidm AND sortest_term_code_entry = :p_term GROUP BY sortest_tesc_code) AND sortest_pidm = :p_pidm AND sortest_term_code_entry = :p_term) SELECT s01.pidm pidm_s01, s01.tesc_code tesc_code_s01, s01.score score_s01, s02.pidm pidm_s02, s02.tesc_code tesc_code_s02, s02.score score_s02, s07.pidm pidm_s07, s07.tesc_code tesc_code_s07, s07.score score_s07, s08.pidm pidm_s08, s08.tesc_code tesc_code_s08, s08.score score_s08, s09.pidm pidm_s09, s09.tesc_code tesc_code_s09, s09.score score_s09 FROM allrows s01, allrows s02, allrows s07, allrows s08, allrows s09 WHERE s01.tesc_code = 'S01' AND s02.tesc_code = 'S02' AND s07.tesc_code = 'S07' AND s08.tesc_code = 'S08' AND s09.tesc_code = 'S09'
The lines will be stored in memory to a temporary table before that product happen (should be faster)...

Not the Win64 is not paused. Of course it was not a priority for work on Win64 since he was moved to the level 3 support in December 2012 as Mozilla putting the Win64 on channel every night on hold before then that is where the idea to be paused. There is a main bug report that must be treated with some potential closer to the occurrence of liberation there.

The ability to stage the generation as funds allow
A motherboard with integrated graphics card has just need to run memory, CPU, disk and enclosure (with power supply). You can add more memory, graphics cards, additional disks, card etc. of its funds allow, and they are all universally available.
A laptop computer has limited or no update from the outset and options are very limited.
While you can't reproduce the portability of a laptop with a desktop PC performance, you can get out the motherboards of small size means that even a game that PC doesn't have to be massive.

What will be the 10.1.4 Adobe Reader Chinese version published?
Hello
I would like to know what will be the 10.1.4 simplified version of the Chinese version of the Adobe Reader available. I work for a company that shipped the drive with our product. We ship the drive with six different languages, among them with the Chinese. For all languages, I need to have the same version. For most languages, we reached 10.1.4,, but for some, including the Chinese, the latest version is always 10.1. Our application deadline is October 15, so if there is not any new released versions until I use 10.1 for all languages.
Thank you,
Márton
10.1.4 is available as a patch for simplified Chinese. Assuming that you already have a contract for the redistribution of player with Adobe (http://www.adobe.com/products/reader/distribution.html?readstep), your should ship 10.1 and let your users update using the integrated update of the drive mechanism.
Alternatively, you can also consult the business guide (http://helpx.adobe.com/content/dam/kb/en/837/cpsid_83709/attachments/Acrobat_Enterprise_Ad ministration.pdf) admin on the bootstrapper section to see how to install the 10.1 and the patch only once.

I want to ask about script.mainly daily backup (archivelog from time ' SYSDATE-3'; "), he takes daily 3 days archivelog backup
What will be the exact command instead (archivelog from time ' SYSDATE-3' ;) ")OPTIMIZATION will ignore all files already saved, so ignore the archivelogs already backed up since a previous backup.
However, given that optimization will not work with THE syntax of the TIME, you must specify your backup as a block:
run { backup as compressed backupset device type disk tag "daily_archivelog" format '/sw/daily11_archivelog_%d_t%t_c%c_s%s_p%p' archivelog all; }
