Forms :: Updating BLOB Column
Mar 11, 2012
I am using Forms 6i,From my Form, user selects "sno" and upload BLOB image through OAF Upload utility. It stores the rowid of "SNO" and image...into Table "t1"...Now, i want to update the BLOB image into the original table"t2" using rowid..For this , i wrote the rowlevel trigger on Table "t1", in the trigger, i called a Procedure...In that procedure .. i am trying to update the BLOB column..It is not updating the BLOB column..But it is updating the Other values.. except BLOB column.

I have a blob column in one table. I need to show it in my form (6i). If i put an image file in the column, it works (because i show it in a Image item type) but if i put a text file in the blob column, it does n´t work.

I have a table named PRODUCT (ID Number , ProductImage BLOB). I have inserted some records in. I want to create a form for user to view this table.
When I create Data Block, in Data Block Wizard, if I select option 'Table or View' to retrieve data, it's ok (Data type of item ProductImage is Image, when I run form and query, it display image normally).BUT, I want to retrieve data from stored procedure in a package. This is my package
PACKAGE my_pkg IS
TYPE my_rec IS RECORD
(
myID PRODUCT.ID%TYPE,
myImage PRODUCT.ProductImage%TYPE
);
[code].....
I select option 'Stored Procedure' in Data Block Wizard, then select my stored procedure (my_pkg.Do_Query). Next I choose 2 columns from my stored procedure (ID, ProductImage). The wizard still applys data type of ProductImage as Image. I finish Data Block Wizard and Layout Wizard... run form, query and an error message display:
FRM-40364: The data type of item 'ProductImage' does not match the corresponding column in the stored procedure.
I try to change 'myImage PRODUCT.ProductImage%TYPE' -> 'myImage BLOB' in my package but still get that error.

I have a non-base-table item which I want to update in the pre-update trigger of the current block.
If the content of the field exceeds 4000 characters, i get the error message
ORA-01461: can bind a LONG value only for insert into a LONG column.
The code is
update tab set long_col = :formsblock.long_col
where tab.tabpk = :formsblock.foreign_tabpk;
Workarounds would be,
1.) to delete the old dataset and insert the new one:
delete from tab
where tab.tabpk = :formsblock.tabpk;
insert into tab (tabpk, long_col) values
(:formsblock.foreign_tabpk, :formsblock.long_col);
or 2.) to change the Item from a non-database item to a database item and use the internal update of the forms-module, but both workarounds are not very satisfying.
Do you know another way to update the LONG-column within the pre-update trigger (or any other PL/SQL part of forms)?

I have little code that's don't really works.
InputStream is = null;
OutputStream os = null;
Connection conn = null;
Blob value = null;
[code]......
I know that there is 90% of Java code. But I have few questions:
I know that I can insert date using INSERT. But is it possible that I can use SELECT and JAVA will know that it need to update the SELECTED column ?

on this query. I need to get a particular value from a column which is a BLOB datatype. Here is the sample
data ID TESTDATA1 Best Buy
00001234 12222 30 00 2
Lowes 00001234 12222 100 00 3
Walmart 00001234 12222 129 00 4
abc 00001234 12222 5000 00 5
Toshiba 00001234 12222 21 00 6
abcdefghij 00001234 12222 49 00
Where '00001234' is the Invoice , '12222' is Netamount field and highlighted in red is the $ amount for that invoice.
The only data i need query to return 12222 (netamount)= $amount. I tried using substr select substr((TESTDATA),19,26)test from TABLEA; But this gives me the only the first row but not other amount which have different positions.
Here is the desired output
OutputID TESTDATA 1
12222 30 2 12222 100 3
12222 129 4 12222 5000 5
12222 21 6 12222 49

I am trying to extract the BLOB column in Oracle Apex and show the contents of it as a popup message.
The files which are stored in the blob column are being zipped using windows zip function in Perl and being inserted in the dataabse using some perl program as follows,
my $zip = Archive::Zip->new();
my $zipfile = $zip->addFile( @$_->[1] ,basename(@$_->[0]));
While extracting the blob column we are using the utl_compress.lz_uncompress_extract() to extract the uncompressed version of file, but we are getting the following error as
"ORA-29294: A data error occurred during compression or uncompression".
I even tried the solution as mentioned in oracle forum

I am trying to find a way to update all of the rows in a table for a column EXCEPT for the very first row. I am not sure if this can be done while I enter my SET parameter or not. I have also thought about using an EXCEPTION in a stored procedure. For example, say I have the table listed below:
SQL> select * from example1;
CODE1 I_ID CODE2 J_ID NAME1 DATE1
----- -------------------- ----- -------------------- -------------------------------- ---------------
A 100 A 200 John 20111225
A 100 A 300 John 20111225
A 100 A 500 John 20111225
A 100 A 400 John 20111225
A 100 A 250 John 20111225
A 100 A 700 John 20111225
A 100 A 800 John 20111225
A 100 A 900 John 20111225
A 100 A 1000 John 20111225
A 100 A 1150 John 20111225
A 100 A 1275 John 20111225
A 100 A 3000 John 20111225
12 rows selected
I am wanting to update the table so that if there were more than 3 J_id's on the table for the same I_id then it will set all of the code1's and code2's to a C except for the very first one. Such as:
SQL> select * from example2;
CODE1 I_ID CODE2 J_ID NAME1 DATE1
----- -------------------- ----- -------------------- -------------------------------- ----------------
A 100 A 200 John 20111225
C 100 C 300 John 20111225

C 100 C 400 John 20111225
C 100 C 250 John 20111225
C 100 C 700 John 20111225
C 100 C 800 John 20111225
C 100 C 900 John 20111225
C 100 C 1000 John 20111225

C 100 C 1275 John 20111225

I have done some searches and haven't seen any results.

when trying to calculate the occupied space for a table, I'm using DBA_SEGMENTS, which works fine as long as the table does not have a BLOB column.
As far as I can tell, the size of the BLOB data is stored with the SEGMENT_TYPE = 'LOBSEGMENT', but I cannot find a view that tells me which DBA_SEGMENT row belongs to the BLOB column in the table I'm checking.
To give you an example:
select sum(BYTES)
from DBA_SEGMENTS
where owner = user
and segment_name = 'MY_TABLE'
group by SEGMENT_NAME
returns 262144
running:
SELECT sum(length(blob_column))
FROM my_table
returns 821333
There are entries in DBA_SEGMENTS for my user with the type LOBSEGMENT, but I cannot find a way to map the correct DBA_SEGMENTS row to the table I am checking.
I'm using Oracle 10.2.0.3.0 on Redhat

i have to update the blob column in a table with new image.
we have a table with 10 columns in which one column is 'image' as BLOB data type, and one more column with "image_name " and has more than 1000 rows.
I have a 300 images which I need to update in "image" column .
I need to match the given images name with "image_name" column, if row is present in the table than update the "image" column with the given image.
I search and found almost same code to insert the image in new table with a procedure, I mean code is to call the procedure, ( by passing image name and image directory)
Is there any way that we will check all the image given in the directory, if that image_name is present in the table then update the image provide me a sample code for this

(1.) We have an Oracle 10g DB.
(2.) We want to store PDFs/MS Word docs inside BLOB column in a table.
(3.) We need to show PDF/MS Word content to the user, without opening the PDFs/MS World like we normally do (i.e. Using PDV reader/ MS Word).
(4.) i.e. We need to use SQL statements and
(a.) Get all contents of the PDF/MS WORD doc.
(b.) Search for specific strings inside these docs in the BLOB columns.

I have a table that has column with BLOB datatype. I am trying read only the inputted String from the BLOB datatype column. I have used the below query,
SELECT utl_raw.cast_to_varchar2(column1) FROM TAB1
and it gives the result as
<H2><FONT color=#cc0000><EM><U>test</U></EM></FONT></H2>
However I would like to extract only the string "test" which is inputted. Is there any build-in function in oracle which will satisfy this requirement?

I have learnt that indexes slow down the DML operations. My question is specific to an update statement. Is it going to be slower if Im trying to update an indexed column on my table or it is slower overall (even when a non-indexed column is getting updated in the table) How does it behave in case of inserts & delete operation.
