Performance after inserting image in a table

Hi all,
I have two tables in Oracle10gR1 database.
One contains personal info and other their images with primary key foriegn key relation.
Performance is ok.
Now our requirment is that we have to incorporate the images in the personal info table itself.
Is there any performance issue is there?
Please help
Thanks in advance.

The answer for this question depends on some required information you didn't voluntarily share.
If the datatype of the image is a BLOB and the BLOB is stored in a LOBSEGMENT, there will be no issue.
If the datatype of the image is a LONG, you will be replacing an optimal solution for a less than optimal solution, and you will likely hit a performance issue. LONGs (a deprecated datatype) are always stored 'inline' in the record.
Doing so, the record might not fit in a block anymore, and you will get row-chaining.
Many years ago, I resolved performance problems in a puzzlegenerator, by removing the graphical representation of the puzzle, stored as a LONG, and by putting it in a separate table.

Inserting Images in a Table

When I insert images in a table and align them right, for
example, there are still a few pixels between the edge of the table
and the image on the top and right.
How do I make an image go to the absolute edge of a table?
Thanks,
Chris

By managing the table's default cellpadding and cellspacing.
Are you
setting them to zero?
If that's not happening then we would need to see your code.

How to insert images in a table

Hi all,
Iam working On Oracle10g
can any one explain how to insert images in a table.
Any help will be much appreciated!!
Thanks.

Hi,
Try like this
step1: Create a folder & place the image in it.
for eg: place the image 'Sunset.jpg' in 'IMAGEFILE' folder of D drive
Step2: Create a Directory in sql*plus as
CREATE DIRECTORY IMAGEDIR AS 'D:\IMAGEFILE';
Step3: Grant previlage to user
GRANT READ ON DIRECTORY IMAGEDIR TO PUBLIC;
Step4: Create the table in which you want to insert the image
create table loadalbum
(name varchar2(100),
image blob)
Step5: Create the procedure as
declare
l_blob blob;
l_bfile bfile;
begin
insert into loadalbum values ( 'Sunset', EMPTY_BLOB() )
returning image into l_blob;
l_bfile := bfilename( 'IMAGEDIR', 'Sunset.jpg');
dbms_lob.fileopen( l_bfile );
dbms_lob.loadfromfile( l_blob, l_bfile, dbms_lob.getlength( l_bfile ) );
dbms_lob.fileclose( l_bfile );
end;
Now you can know whether the image is inserted or not by
SELECT COUNT(*) FROM LOADALBUM;
COUNT(*)
1
which means image is inserted.
Hope this may help you.

Refresh LOV after inserting data in correspondent table

Hi all,
I am using Jdeveloper 11.1.1.2 and ADFBC.
I have a page with a table (tableA) with some fields. One of them has a LOV associated to another table(tableB). I have a button (button1) that shows a popup(popup1) and opens a new task flow with a fragment to insert data in the tableB.
After inserting/modifying rows in tableB and after pressing commit (property: end-transaction) or rollback buttons (property: end-transaction and restore save point), LOV does not refresh.
I have tried to set the property partial triggers of the LOV to button1 or popup1 and it does not work.
How can I solve it?
Thank you.
Andrea

How about VO for table B ? Did you refresh that ? I didn't use the same VO for table & LOV.
so in "List data Source" -- VO -- I am using "SQL statement" and statement includes fields from Table B and Table A.
VO for LDS using "Rows populated by a SQL query with read-only access". I didn't use "Updateable Access through Entity Objects".
Sample of VO of LDS:
select A.model_number modelNumber, a.part_number partNumber, b.MODEM_TYPE ModemType
from table A a,Table B b
where a.PART_NUMBER_ID = b.PART_NUMBER_ID
and a.part_number_id =:partID

Inserting image in a table using php +zend

Hy!
The table is
(products(picture_p blob,prod_id number)) when i try to insert the pictureusing a similar code with this from oracle .com:
// Insert the BLOB from PHP's tempory upload area
$lob = oci_new_descriptor($conn, OCI_D_LOB);
$stmt = oci_parse($conn, 'INSERT INTO BTAB (BLOBID, BLOBDATA) '
.'VALUES(:MYBLOBID, EMPTY_BLOB()) RETURNING BLOBDATA INTO :BLOBDATA');
oci_bind_by_name($stmt, ':MYBLOBID', $myblobid);
oci_bind_by_name($stmt, ':BLOBDATA', $lob, -1, OCI_B_BLOB);
oci_execute($stmt, OCI_DEFAULT);
// The function $lob->savefile(...) reads from the uploaded file.
// If the data was already in a PHP variable $myv, the
// $lob->save($myv) function could be used instead.
if ($lob->savefile($_FILES['lob_upload']['tmp_name'])) {
oci_commit($conn);
else {
echo "Couldn't upload Blob\n";
$lob->free();
oci_free_statement($stmt);
// Now query the uploaded BLOB and display it
$query = 'SELECT BLOBDATA FROM BTAB WHERE BLOBID = :MYBLOBID';
$stmt = oci_parse ($conn, $query);
oci_bind_by_name($stmt, ':MYBLOBID', $myblobid);
oci_execute($stmt, OCI_DEFAULT);
$arr = oci_fetch_assoc($stmt);
$result = $arr['BLOBDATA']->load();
// If any text (or whitespace!) is printed before this header is sent,
// the text won't be displayed and the image won't display properly.
// Comment out this line to see the text and debug such a problem.
header("Content-type: image/JPEG");
echo $result;
oci_free_statement($stmt);
oci_close($conn); // log off
?>
I get an error -can't open file htdocs/ phpA.tmp
please if you have an idea from where it could be the error reply

It looks like your webserver doesn't have read permissions on the directory and files within it. In Linux, set it to 755, in Windows, I'm not sure what needs doing sorry.

Performance issue - insert records from db2 tables

I have a table say emp in oracle database and i have the emp table in db2 database. My job is to pull all the records (million records) from db2 table to oracle emp table. My insert statement is like below. I am connecting to the db2 database using dblink.
insert into emp
select * from emp_db2, dept_db2
where emp_db2.dno = dept_db2.dno
and dept_db2.dno = 10;
The statement is still running. How to improve the performance ?
please suggest.

Inserting images into a table

Hi All,
Can any one tell me how to create a table(with which data type) to insert a jpg/gif files into that table and how to retrieve it using D2k.
Thanks in Advance
devender

Hi ,
You can use a BFILE to store a jpg/gif files
into a table.
About Retrieving it from D2K you can use :
READ_IMAGE_FILE.
( Look up in the Oracle doc. for something
similar ).

Inserting image to table...ORA-22288: file or LOB operation FILEOPEN failed

Good day!
I'm just new with using databases, and i'm enjoying it.
So I read that you can insert images to a table, and so i decided to try it... and here's where I'm at..
*I made a directory
CREATE directory image_dir as 'D:\Images';
--Directory Created.
*I created a table
CREATE TABLE animages
(aname VARCHAR2(40),
breedno NUMBER(10),
image_file BLOB,
image_name VARCHAR2(40),
CONSTRAINT aname_fk FOREIGN KEY (aname) REFERENCES clist(aname));
--Table Created.
*Then I made a procedure for inserting the images
CREATE OR REPLACE PROCEDURE insert_image_file (p_aname VARCHAR2, p_breedno NUMBER, p_image_name IN VARCHAR2)
IS
src_file BFILE;
dst_file BLOB;
lgh_file BINARY_INTEGER;
BEGIN
src_file := BFILENAME('IMAGE_DIR', p_image_name);
INSERT INTO animages
     (aname, breedno, image_file, image_name)
VALUES (p_aname, p_breedno, EMPTY_BLOB(), p_image_name)
RETURNING image_file
INTO dst_file;
SELECT image_file
INTO dst_file
FROM animages
WHERE aname = p_aname AND image_name = p_image_name
FOR UPDATE;
DBMS_LOB.fileopen(src_file, DBMS_LOB.file_readonly);
lgh_file := DBMS_LOB.getlength(src_file);
DBMS_LOB.loadfromfile(dst_file, src_file, lgh_file);
UPDATE animages
SET image_file = dst_file
WHERE aname = p_aname AND image_name = p_image_name;
DBMS_LOB.fileclose(src_file);
END;
--Procedure Created.
*So i was able to do those but when i was trying to execute the procedure i get this error..
execute insert_image_file('African Elephant', 60, 'African_Elephant');
ERROR at line 1:
ORA-22288: file or LOB operation FILEOPEN failed
The device is not ready.
ORA-06512: at "SYS.DBMS_LOB", line 523
ORA-06512: at "SCOTT.INSERT_IMAGE_FILE", line 18
ORA-06512: at line 1
I've been looking for a solution for a day now, hope someone could help me, thanks.
BTW, I got the code for the PROCEDURE from a user named Aparna16, just did some minor editing so it would fit my tables, thanks.
And sorry if the post is too long.

Hi;
ORA-22288:Error:     ORA-22288
Text:     file or LOB operation %s failed %s

Commit after insertion

I use Oracle 10G Rel2. I'm trying to improve the performance of my database insertions. Every two days I perform a process of inserting 10000 rows in a table. I call a PL/SQL procedure
for inserting every row, which checks data and perform the insert command on the table.
Should I commit after every call to the procedure ??
Is it better to perform a commit at the end of calling 10000 times to the insertion procedure?? So the question is : is "commit" a cheap operation ??
Any idea to improve performance with this operation ??

> So the question is : is "commit" a cheap operation ??
Yes. A commit for a billion rows is as fast as a commit for a single row.
So there are no commit overheads for doing a commit on a large transaction versus a commit on a small transaction. So is this the right question to ask? The commit itself does not impact performance.
But HOW you use the commit in your code, does. Which is why the points raised by Daniel is important.. how the commit is used. In Oracle, the "best place" is at the end of the business transaction. When the business transaction is done and dusted, commit. That is after all the very purpose of the commit command - protecting the integrity of the data and the business transaction.

How can I recover BFILE images from a table?

I`m a Spanish student, so excuse me for my poor english.
I have used LOB objects to insert images into some tables of a DataBase. However, I have tried to recover the inserted images to put those into a Developer 6 Form, and I haven4t done it.
?Have I need an specific procedure?
?Is There some option in Developer 6 to do it easily?
Please, help me.

If you have access to a PC I believe - if memory serves me correctly - that the free download SubRip can rip the highlight overlays back to graphics files from the Menu VOBs
There is a subtitle ripping program for Mac - D-Subtitler - which may do the same job but I have never found it to be as good at ripping stuff as SubRip.
I guess the only other way is if they are not too complex is to recreate the overlays in Photoshop using frame grabs for reference?

Inserting images in a collapsible panel

Can anybody help with a problem about inserting an image into
the tab of a collapsible panel as a visual clue to users that they
can open/close the panel? I'm trying to ensure that users don't
just see the tab of the panel as a kind of good looking heading but
that the images (two - one for open, one for closed) would give a
visual clue that the tab actually opens when clicked.
I'd be very grateful for any help, thanks, st44

Oracle 10g - Insert in to Temporary Table - Record count mismatch between s

We are trying insert records from a select query in to temporary table, some of the records is missing in the temporary table. The select statement is having multiple joins and union all which it little complex query. In simple terms the script contains 2 part 1st Part Insert in to temporary table 2nd part Select query with multiple joins, inline sub queries, unions and group by classes and conditions
Eg. If we execute select statement alone it returns some count for example => 60000 After inserting into the temp table, in temp table the count is around 42000 why is the difference?
It is simple bulk inserts... insert in to temp table select from xxx. also, there is no commit in between. The problem is all the records populated by the select statement are not inserted in to temp table. some records are not inserted.*
Also, we had some other observation. It only happens in its 2nd execution and not its first run. Hope there might be some cache problem
Even, we also did not believe that. We are wondering. In TOAD, we tested however at times it happens. In application jar file, after "insert in to temp select * from xxx" we take the i. record count of temp table and ii. record count of "select * from xxx" separately but both doesn't match. Match only at 1st time.
Thank you in advance for your efforts and help.
Shiva.

The code looks like
sql = "insert in to temptable select x,y,z,.... from xxx,abc,pqr..where...."; (logial but not real is very complex around 700 lines with multiple joins, inline sub queries, group by etc. )
stmt = conn.createStatement();
rCount= stmt.executeUpdate(sql);
Actual issue is
rCount = xxxx = Count(temptable) < count(select x,y,z,.... from xxx,abc,pqr..where....)
why this diffference ? some records populated in the select but not inserted in to temp table
Anyone can explain?

Send e-mail sing trigger after insert

Hi,
I need to intiate a trigger in oracle dB after inserting a
record to table I need to send a e-mail to specified person.
This trigger should be cnditional.
eg. Table emp
columns: name dep sal
on insert of every record to this table and when dep code is 3 I
should send e-mail to named person.
Please give me code examples.
thanks

Hi,
Maybe what you are looking for is the db package UTL_SMTP?
If you're using Forms, go to the Navigator, Database Objects,
choose SYS schema and open Stored Program Units. If it's not
there, contact your DBA. I'm not sure if it's available for
databases prior to 8.1.6
Hopefully, the package spec will have some examples that you can
use.
Good Luck,
