View 8 Replies View Relatedi 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

PIC = image
I want to read all the files present in a directory of client's machine.
However I have achieved this by creating java class in database but the problem is it accesses the directory of machine on which database is installed not the client's machine.
I have oracle client and I tried to access local directory of client's machine to read all the files in that directory but it didn't work.
However, I achieved this by creating one java class for ex. test.class and I run it locally through command prompt but I want to achieve it using Pl-sql.
i have one directory in this directory contains 100 file these files are related to table structured creation with dependence
so how to read file names from directory and executed in scheme with logs also
procedure or script
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 created a standby database yesterday and everything is working correctly. I need to make some tweaks, however, and one of those is the directory that the standby database expects the archivelogs to be.
I found that the archivelogs were being shipped to $ORACLE_HOME/dbs and named arch*.arc. Interestingly a log switch ships the archivelog minus the "arch" at the front and all archivelogs now do not have that format. I moved the archivelogs to the correct location and renamed them. I have been able to set the correct location using standby_archive_dest and can see that the archivelogs are shipped to there.
Also, v$archived_log shows the correct path and filename. The problem I have is that when I come to apply the archivelogs it still seems to think that they should be in $ORACLE_HOME/dbs and named with "arch" at the front. what parameter I need to change to tell oracle the correct path and filename to use when applying the archivelogs?
we have a created primary and physical standby databases. Before the switchover the application connected to dataguard allows updates on the database. However after the switchover, it allows read-only access and we are unable to update. Any comments prima-facie ?

I have a table containing BLOB column which stores scanned images. Due to an application error, few extra data was padded with BLOB data and now we want to remove it.
The table count will be near to 10 million rows.
We need to remove data from 161byte to 167byte of the blob data. I tried to do with DBMS_LOB.ERASE.But it will create blank spaces for the removed data. Here we need to reduce the size of BLOB data by 6 bytes by removing data from 161bytes to 167 bytes.
I have one question. Is there any way to get some users data from active directory? I already have authentication scheme wich interact with AD, but now I need to get e-mail address from user who will login into application. Our Apex version is 4.1.

I have oracle 10g up and running on Solaris 10, from windows I would like to connect to sql plus through windows authentication, for that I have already made sure that remote_auth = true and have created user in oracle with OPS$. But still I cannot connect.
I have the same setup but with oracle on windows server, the os authentication from windows clients works just fine.
does oracle 10g on solaris 10 supports windows os authentication?
