• How can I make sure that a CLOB column is unique

  I have a table with a CLOB column I want to ensure is unique. If the column is VARCHAR2 I could use a unique index.

  The maximum size of a column report CLOB value is 32 KB. However, the maximum size for the content of the line of the full report is also 32 KB (including the HTML markup), so you can be hitting this limit because of the size of your 10 K CLOB data + the rest of the line.

  According to the database character set and the characters which that contains data, the character encoding may use more than one byte to represent a character.

• Download file in/from DB Oracle Clob column

  Hello

  12.1.3 Jdev

  I have a database table that has a Clob column to store the file and a varchar2 column to store the file name.

  I want to have a screensaver to download files in this table.

  Would like to know the best way to achieve this functionality.

  See you soon

  AJ

  The files are usually stored in BLOB column (and not on the CLOB type)

  Here is an example that you can follow: https://tompeez.wordpress.com/2011/11/26/jdev11-1-2-1-0-handling-imagesfiles-in-adf-part-2/

• Ask the CLOB column (with XML content)

  1. how to extract a particular xml tag value for a column with the CLOB data type.

  Example:

  < REQUEST_DETAIL >

  PR < GROUP_TYPE > < / GROUP_TYPE >

  < GroupName > ASSET MANAGEMENT TECHNICAL DATA < / GroupName >

  < BUS_UNIT_ACRN > SCS-FCAT < / BUS_UNIT_ACRN >

  < PROJ_MGR_ID > < / PROJ_MGR_ID >

  < PROJ_MGR_NAME > Roland Roy < / PROJ_MGR_NAME >

  < / REQUEST_DETAIL >

  Select

  XmlType (provable). Extract('/REQUEST_DETAIL/GROUP_TYPE/text()').getStringVal)

  e t

  /

  example above works.

  If I do not know the order of xml tag to ask how can I get the value.

  (/ * * / / * * / REQUEST_DETAIL/GROUP_TYPE / * / *)

  2 using the DBMS_LOB. SUBSTR takes longer to run and it never returns results and session will wait status for access to LOB_INDEX content (at the same time the CLOB column is used by the application).

  Y at - it another option for faster results.

  SELECT DBMS_LOB. SUBSTR (xml_blob, 4, DBMS_LOB.) INSTR (xml_blob, "< name >", 1, 1) + 6) name.

  status,

  CNT to COUNT (*)

  OF LOG_TBL

  WHEN TRUNC (IO_DATE) = TRUNC (SYSDATE)

  GROUP OF DBMS_LOB. SUBSTR (xml_blob, 4, DBMS_LOB.) INSTR (xml_blob, "< name >", 1, 1) + 6),

• Getting string of a CLOB column

  Hi team,

  I have a problem. as if I had the table that contains a CLOB column. Since I need to extract exactly a word string. I'll give an example on how it will be below.

  Let T_OBJ of Table has a WORK_LOG column that is a CLOB.

  The CLOB data is huge, but since I need to extract a string, containing the name that falls exactly after a WORD

  Create table T_OBJ (SNO number, WORK_LOG clob);

  Insert into T_OBJ values (1, '1263636000 AR_ESCALATOR. amended by XXXXXXXXX XXXX ("This is Auto Closed.Change was closed")

  How is the sample data. But what I found most is there are the delimiters in the text. A delimiter is exactly after name i.e. XXXXXXXX XXXX (delimiter)

  My output should be one name i.e. XXXXXXXX XXXX, which falls immediately after the text "modified by".

  I tried like this

  Select dbms_lob.substr (WORK_LOG, 50, dbms_lob.instr (WORK_LOG, "modified by"))

  of T_OBJ;

  Can someone help me please. I'm using ORACLE 11 g.

  Hello

  Check if the query below matches your needs.

  SELECT dbms_lob.substr(WORK_LOG
                        ,((dbms_lob.instr(WORK_LOG,'.',dbms_lob.instr(WORK_LOG,'Modified By ')))-    --- get position of DELIMITER AFTER MODIFIED BY
                         (dbms_lob.instr(WORK_LOG,'Modified By ')+length('Modified By ')))           --- get position of MODIFIED BY

• Read CLOB column - by bursting

  I have two tables File_Master and File_Detail
  Primary key File_Master FILE_ID
  Primary key File_Detail FILE_ID, LINE_ID
  
  I have a CLOB FILE_CONTENT column table File_Master.
  For each record FILE_ID in File_Master, hundreds of lines are stored in the CLOB column.
  
  I want to read this 'File_Content' CLOB column and and break each line (1000 characters)
  by pieces to fill the columns in File_Detail.
  
  Since there will be thousands of lines in the process, what would be the best approach when writing PL/SQL code for better performance?

• How to view the report on one Clob column online?

  Hello
  
  In a set of columns in the report created with the wizard to create a Page, a Clob column is made that resembles a dozen lines high. The other elements are the high standard of a line. How can I load Apex to restore the Clob, the same height as the other columns (on one line)? Left like that, I'll only be able to see 2 or 3 lines at once, even if there is very little data in Clob columns.
  
  I would have attached a screenshot, but I do not see this feature on the forum site.
  
  BTW, I guess this is a common newbie question. I don't see an answer in the Forum or in the documentation. Your response is appreciated.
  
  Thank you

  Unfortunately, at this stage of my Apex maturity, it would be very difficult for me to reproduce the problem on apex.oracle.com (don't laugh, Jedi are not built in a day).

  It's very simple.

  1. sign up for an account on apex.oracle.com.
  2. in your local installation of the APEX, go to SQL Workshop > utilities > generate DDL. Click create a Script and use the wizard to generate a DDL script that contains the objects of database required by your application. (You can find out what they use Application Builder > Application > utilities > database object dependencies.)
  3. your local installation of APEX export demand.
  4. download and run the DDL file on apex.oracle.com using SQL Workshop > Scripts SQL.
  5 import the request to apex.oracle.com.

  So I resort to ad a page to SkyDrive. When you see the picture, the question will be very clear and I guess that there is a way to dusty solution tucked away in the vault. Note: I would like to limit the height of the text element, not the width of it. Here's the URL for the screenshot.

  Go to the Notes column attributes. Define the number of rows to 1 and the attributes of the element to

  style="height: 1.3em;"
  

  You may need to adjust the height to match other items. (Or according to browser [s], may not need any: in Firefox on Windows 7 14 "number of lines: 1" seems to mean "number of rows: 2". ") (Go figure.)

• Text is wrapped in the clob column

  I have a table with a clob column. I'm loading using PLSQL block:
  
  declare

  Start
  v_sql: = q'{text
  ....
  ....}';
  insert into values tb1 (v_sql);
  commit;

  However, if a line is long in my thong and then wraps the line and a single sentence is transformed into two. Please suggest how I can fix it. I use 11g.

  PS why are you eager to store SQL statements in a table? Looks like poor design to me.

• with package htp clob column

  All,
  I need assistance with data in clob column display dynamic content with any appropriate package but iam currently using htp.p, it seems to not work well. Some of my clob values are so big like length > = 18000 but when I use htp.p all the output text is collected without any line break, but I want to display the data IS STORED in the column to the table... any help is appreciated thank you.

  I think you can maximum diisplay 32 767 characters. You need to replace Chr (13) and Chr (10) with

• Line terminator of parameter for a CLOB column by script

  Hi all
  
  I have a CLOB column in my table that receives the external data (more than 400 sources).
  The GUI application it displays in multiple different ways due to the incoming line terminators.
  
  Here's the strange thing:
  In Developer SQL 3.1.06. I chose in preferences-> environment, as line terminator: carriage return and line Fe (Windows)
  Once I committed changes to the data has been properly displayed in the application (apparently was also recoding).
  
  My Question is:
  How can I configure this property to the column or table to solve the problem?
  (I'm looking for a DDL script or something like).
  
  Thanks in advance.

• Oracle Streams and CLOB column

  Hello
  
  We use "Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64 bit. My question is "Does Oracle Streams capture, spreads (source capture method) and applies the CLOB column changes?"
  
  If so, is this default behavior? Can we say Brooks to exclude all of the CLOB column (capture-spreading-request) process?

• Add information to the byte to clob column

  Hi all
  
  We need to change a CLOB column with 160 bytes of data that are added based on binary data, that is added before the actual binary data
  The information to be appended is Personid (NUMBER), (CHAR) type of the Image and Image Code (CHAR)
  
  160 bytes-
  1 - 0x00
  2-21: equivalent PersonID byte (length = 20). For personid, only 9 bytes to use remaining should be defined as 0x00
  22-24: Image type equivalent byte (length = 3). If the type of image length less than 3, as 0x00
  25-28: equivalent byte Image Code (length = 4). If the image length less than 4 code, set it as 0x00
  29-160 - 0x00
  
  Is it possible through PL/SQL or only application level we can achieve this?
