EMPTY_BLOB() doesn't work
I have a table in schema with a BLOB field. I store employee's picture in this field. Fields in this table are emp_id (number) emp_name (varchar2) and emp_photo (BLOB). I want to ask if there is a way in pl / sql that i could empty this BLOB field to null or reset this field so that user can change the saved photo graph and save another one.
what i am looking for is something like
alter table employee set emp_photo = empty_blob() or alter table employee set emp_photo = null
how to insert into a BLOB column. I have stored procedure with an input parameter of type BLOB now how do I insert this BLOB into a table.
View 2 Replies View RelatedI have a table with a column of type blob. Now i want to create a procedure which will insert into that table. But I don't like to create a directory. How can i solve this.
I want to insert a row like this:
insert into table x(image)
values('d:photo est.jpg');
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 using Forms 6i,From my Form, user selects "sno" and upload BLOB image through OAF Upload utility.

View 2 Replies View Relatedwhen 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 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

- I created a table with 2 columns id (datatype as number) and file_content datatype as BLOB.
- My question is under desc filetable; query why does it not show me a data type as BLOB.
- create table query does not return any error to me. How do I verify that FILE_CONTENT column has datatype as blob.
I use the oracle 10g database.I am trying to insert and retrive the image.Inserting an image is done.but while retrieving an image iam getting an run time exception in java "java.sql.sqlexception:general error".i am not able to understand this.
The code to insert the image is
FileInputStream fi=new FileInputStream(f);
int size = fi.available();
System.out.println("j"+size);
byte b1[] = new byte[size];
i=fi.read(b1,0,size);
System.out.println("i"+i);
st.executeUpdate("insert into image1 values('b1',"+k+")");
when i am retrieving the image i tried like this
ResultSet rs=st.executeQuery("select imagecolumn from tablename");
here iam getting an exception as i named above.
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 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.

we received a design advise to add columns to track the update and delete done on each row in our tables:
- DELETED_DATE_TIME
- DELETED_BY
- UPDATE_DATE_TIME
- UPDATED_BY
In our architecture, the application can only access functions/procedures to access/modify data. Each function logs the action, the executed sql statement, oracle error, user terminal, and the user into a unified log table by using v$ tables to create a general log function that is called after execution or error.
The only advantage is that it will be easier to know the delete and last update information faster versus space and design modification.
I have to write a procedure that accepts schema name, table name and column value as parameters....I knew that i need to use metadata to do that deleting manually.
