  How to insert a pdf or jpeg image into a column of type blob of a table

  Hello
  Try this

  Loading an image into a BLOB column and showing through OAS
  -------------------------------------------------------------

  The steps are:

  Step 1.
  -------

  Create a table to store BLOBs:

  create BLOB table objects
  (id VARCHAR2 (255),)
  blob_col blob
  );

  Step 2.
  -------

  Create a logical directory in the database to the physical file system:

  create or replace the MY_FILES directory as "c:\images";

  Step 3.
  -------

  Create a procedure to load the BLOB from the file system by using the logic
  Directory. Gif 'aria.gif' must exist in c:\images.

  create or replace procedure insert_img as
  f_lob bfile.
  b_lob blob.
  Start
  insert into BLOB ("MyGif", empty_blob()) values
  return blob_col in b_lob;

  f_lob: = bfilename ("MY_FILES', 'aria.gif');
  DBMS_LOB. FileOpen (f_lob, dbms_lob.file_readonly);
  DBMS_LOB. LoadFromFile (b_lob, f_lob, dbms_lob.getlength (f_lob));
  DBMS_LOB. FileClose (f_lob);
  commit;
  end;
  /

  Step 4.
  -------

  Create a procedure that is called via Oracle Application Server to display the
  image.

  create or replace procedure get_img as
  vblob blob.
  raw buffer (32000);
  buffer_size integer: = 32000;
  offset of an integer: = 1;
  length of number;
  Start
  owa_util.mime_header('image/gif');
  Select blob_col from vblob of blobs where id = 'MyGif. "
  Length: = dbms_lob.getlength (vblob);
  While offset< length="">
  DBMS_LOB. Read (vblob, buffer_size, offset, buffer);
  HTP. PRN (utl_raw.cast_to_varchar2 (buffer));
  offset: = offset + buffer_size;
  end loop;
  exception
  while others then
  HTP.p (SQLERRM);
  end;
  /

  Step 5.
  -------

  Use the PL/SQL cartridge to call the get_img procedure

  OR

  Create this procedure in function and call it your PL/SQL code for
  correctly place the images on your HTML page through the PL/SQL Toolbox.

  from a html form

  1. create an HTML form where the image will be. You too
  need the file MIME type.
  2. create a procedure receives the form parameters. The file field will be a Varchar2
  parameter, because you receive the path of the image is not the image itself.
  3 insert the image file into the table by using 'Create a directory NAME as chemin_image' and
  Then use ' insert into the TABLE (row, BLOB_OBJECT, MIME_OBJECT) values (sequence.nextval, '.
  EMPTY_BLOB() 'GIF' or 'JPEG') BLOB_OBJECT, in the variable_blob, back
  variable_consecutive.
  4 load the file into the table using:
  DBMS_LOB. LoadFromFile (variable_blob, variable_file_name, dbms_lob.getlength (variable_file_name));
  DBMS_LOB. FileClose (variable_file_name);
  engage.

  Hi a cold sore.

  In addition to above solution to pass like a Flash of using PL/SQL blob that follows is solutions to compress blobs using Java and PL/SQL:

• Browse file... Column of type BLOB specified in the attribute of the Source element

  Hello world

  I'm trying to insert images as blobs in a database table. I followed the tutorial in the following link, but I'm always redirected to the de.../wwv_flow.accept/ page, which is the page that follows an insertion in the file Explorer WWV_FLOW_FILES table method. The file inserted into the APEX_APPLICATION_FILES table instead of the new table that I created.

  http://oraexplorer.com/2011/03/file-browser-in-Apex-4-with-BLOB-column-specified-in-item-source-attribute/

  FILE BROWSER:

  

  
  

  LINE (DML) AUTOMATIC PROCESSING:

  

  P100_A4 is simply the maximum ATTACH_ID (PK) + 1

  I just want to insert my files from the file Explorer in this table with the name of file, mime_type and 2 fields of my choice. I use apex 4.2.5. Any help is very appreciated.

  Look in the thread below. The issue I described here has been resolved in this link through other means.

• Column of type BLOB in own tablespace in partition in the table, tablespace to move

  Hi all

  First off I use Oracle Database 11.2.0.2 on AIX 5.3.

  We have a table is partitioned on a monthly basis.

  In this table, there is a partition (BOTTOM), this lower score is 1.5 TB in size thanks to a BLOB column called (ATTACHMENT).

  The rest of the table is not large, about 30 GB, it's the BLOB column that uses all the space.

  The lower part is in its own default tablespace (DefaultTablespace), the BLOB column in the lower score is also in its own tablespace (TABLESPACE_LOB) - 1.5 to

  I was invited in order to free up space by moving the TABELSPACE_LOB (from the low partition) to a data archive, confirming the data is there and then remove the lower score of the production.

  I do not have enough free space (or time) make an expdp, I think not only its doable with data so much.

  CREATE TABLE tablename
  (
    xx                          VARCHAR2(14 BYTE),          
    xx                          NUMBER(8),    
    xx         NUMBER,
    ATTACHMENT   BLOB,
    xx             DATE,
    xx             VARCHAR2(100 BYTE),
    xx                     INTEGER,
  )
  LOB (ATTACHMENT) STORE AS (
    TABLESPACE  DefaultTablespace
    ENABLE      STORAGE IN ROW
  NOCOMPRESS
  TABLESPACE DefaultTablespace
  RESULT_CACHE (MODE DEFAULT)
  
  
  PARTITION BY RANGE (xx)
  ( 
    PARTITION LOWER VALUES LESS THAN ('xx')
      LOGGING
      COMPRESS BASIC
      TABLESPACE DefaultTablespace
      LOB (ATTACHMENT) STORE AS (
        TABLESPACE  TABLESPACE_LOB
        ENABLE      STORAGE IN ROW
  )
  
  ...>>
  
  

  My idea was to take a table, excluding the attachment column datapump, export using external tables.

  Then to create the table on the database archive 'with' the attachment column.

  Import data only, as I understand that if you use a dump file that has too many columns Oracle he will manage, I hope it will work the other way around.

  Then on the production, make the TABLESPACE_LOB read-only and move it to the new file system.

  It's a little more complicated that a normal gesture of tablespace because of how the table is split.

  Any advice would be much appreciated.

  I was thinking about an approach as:

  SWAP PARTITION allows to separate the partition of the table

  • Create a non-partitioned table which is otherwise identical in structure to tablename (nonpart_tablename)
  • ALTER TABLE TableName LOWER WITH nonpart_tablename SWAP PARTITION

  Move the segment of the table at TABLESPACE_LOB, or to a different tablespace on its own. It is, as you say, only 30 GB and I think (but not strongly enough to go forward without testing/validation on a smaller scale) that the displacement of the segment of the table in this way does not disrupt the LOB segment, as long as you don't say MOVE LOB.

  • ALTER TABLE nonpart_tablename MOVE TABLESPACE TABLESPACE_LOB

  Now the TABLESPACE_LOB tablespace is self-contained and you can make it transportable.

• How to download all the images in the folder to the column of type BLOB (problem of area to create BLOB)

  Hello

  I use JDeveloper 11.1.2.3 version, I need to download all the images in my local folder to the database at a time table. The problem I face is to create BLOBDomain for each of them?

  Best regards,

  Julien

  If you can access the files, that only works if they are on the server, you can read the file and create the domain of the BLOB in the file directly. The technique is the same as in the blob. Only difference is that you pass the file to the method and open the input stream of the file instead of the UploadedFile.

• Upload of file outside APEX call

  Hello
  
  I would like to upload documents to the apex of mass flows_files schema. Initially, I thought that I could 'just' inserts records in the WWV_FLOW_FILE_OBJECTS table $, but now I think that it is not a good idea, because I don't know how to generate all the columns (primary key, for example.)
  
  Is there a legal way to do this? Call a web service or something? Each index is much appreciated.
  
  Tamas

  Tamas,
  as you say, it comes to unstructured data, but these documents come from a single directory?
  I mean, how to find a particular document in a folder of 3000?
  There must be a rule, a method for recovery of a particular document, by name, date modified, by the owner, you cannot browse 3000 documents every time, you can?

  If this new application takes care of the entire Organization document concerns, so you can create your own table that contains a column of type BLOB and enjoy support declarative BLOB of Apex for downloading files.

  Said that probably the best way to make a download of mass would be to put all these files in a folder that put you at the disposal of the DB using the command CREATE a DIRECTORY, then you treat files using a utility built on top of DBMS_LOB. LOADBLOBFROMFILE.

  You need a way to store the names of files from the beginning, because you can not browse the contents of the directory, you need to know in advance the name of the file to load, but I guess that you can create a table containing the names of the files and then you can browse the rows of this table.
  Clearly, this method makes sense if this is a one-time operation, if you need to repeat this process over time, then it may be desirable to engineer this process a bit more.

• How to insert a column of type long raw

  Hi all
  
  I'm trying to copy a record with a column of type long raw.
  But it raises an error ORA-00997: illegal use of the long data type.
  
  For example, the HR employee table: PER_IMAGES
  
  INSERT INTO per_images (image_id, parent_id, table_name, image)
  SELECT 21,10, 'test', images OF per_images WHERE the image_id = 2
  
  It triggers ORA-00997: illegal use of the long data type.
  
  It cannot be resolved by the statement "copy of" ("copy of" only works for the LONG data type, not LONG RAW datatype)
  
  We try to export the data in long-raw format source to the BLOB data type.
  And then insert BLOB of long-crude recording of destination.
  (i.e. long-raw > > to_lob(long-raw) > > BLOB > > long-crude oil)
  It works without any error message, but there are empty picture in the destination folder.
  
  Is there a function of BOLB in LONGRAW data conversion system?
  
  Our version of the database is 9i.
  
  
  Any suggestion will be appreciated.

  By the way I couln t understand what were you thinking when you explain to no.

  I missed you NVARCHAR2 column and thought it was VARCHAR2. When you declare the semantics of VARCHAR2 column length is specified explicitly or implicitly. Explicitly suffixing length with BYTE or CHAR and implicitly when you specify the length of the right itself. Then length is based on the value NLS_LENGTH_SEMANTICS session. So let's assume you generate table create statement (and it seems that you is, based on column_name |) » '|| DATA_TYPE | » ('|| ( data_length|') ' ). Then it does not matter if use use data_length or char_col_decl_length. It will be regadless semantics implied length of what you use. Therefore, when you run create table instructions column length will be interpreted as bytes if current NLS_LENGTH_SEMANTICS byte value. But same length is interpreted as the characters if current NLS_LENGTH_SEMANTICS a char value. As you can see, in order to generate create table statement we use explicit semantic length column, otherwise create table statement can produce lengths of different column in the source table.
