• The search for Clob columns in interactive report

  I use APEX 3.2 with 10g. I have an interactive report with a query that takes several recordings of 'comments' and the concatenates using a function that returns a Clob. In the report, there are several of these comments columns mixed with some small varchar2 columns.
  
  Using the search bar, if I type in a Word and click OK, it does not seek my Clob columns. On the other hand, I can use the drop-down list in the search bar to indicate I want to only search one of these Clob columns, then the research works.
  
  Is there a reason that my filters 'Text line contains' do not include my Clob columns? I have defined, as the "Standard report column" and they all "filter" checked as a permitted operation.

  I found a work around for this problem. IR reports do not seem to automatically search for CLOB columns as a search ROWTEXT (unless you are specifically targeting this column). So, I wrapped the CLOB column with:

  DBMS_LOB.substr(clob_column_name,4000,1)

  This converts the CLOB Varchar2 column, which made the report «see» IR Of course, this only works if you want to search for the first 4000 bytes, but the data in my CLOB columns are never more than a few sentences long.

• How Index on a CLOB column?

  I have a need index on a CLOB column. The first attempts to index will result in ORA-02373.
  In research, I was able to find one that a LOB column could be moved to a different tablespace then indexed.
  
  So I intend to use these statements (see below), to create a text index on column CLOB STATEMENT_TEXT.

• Insertion in textarea CLOB column

  Hello people,
  
  I'm trying to find out if it is possible to insert data greater than 4000 characters in a text box in a clob column. Although CLOB supports larger data size, the page generates an error when the content in the text box exceeds 4000 characters for obvious reasons. The insertion in the clob column goes through a submit after pl/sql block.
  
  We have an option for users to download files, but users are more interested in the ability to copy paste data in the text box so that they can be searched on through the search screen that we have provided for this clob column.
  
  Including search through dbms_lob.instr is an alternative before us, but just curious to know if there is a solution for the insertion of text box in a clob data column greater than 4000 characters.
  
  Appreciate your help.
  
  Concerning
  Krishna

  APEX knows not what is a clob. Thus, in the first variant of SQL
  I'm writing a process this filling instead of SQL query textarea

  In the second variant your function returns a clob. Apex doen't know what what is it and raise the exception. I rewrite your PL/SQL function

  declare
   t varchar2(32000);
   c clob;
  begin
   SELECT txt into c FROM clob_test WHERE ID = :P3_ID;
   t:= dbms_lob.substr(c,32000,1);
   return t;
  end;
  

  It will ensure the correct data type conversion.

• Using the TRIM output as a parameter for IN

  I have a CLOB containing column (for example):
  

  ,1074,1075,1076,1077,1078,1050,

  The idea is to use values of this field in another query as a parameter for IN selection (basically something like this:)

   SELECT columns FROM table WHERE column IN (values from previous field);

  If I run:

   SELECT columns FROM table WHERE column IN (1074,1075,1076,1077,1078,1050);

  (values entered in the statement) everything is ok. But the problem is that this original area also contains comas at the beginning and at the end.
  
  In order to deal with them, I tried:

  TRIM(',' FROM column)

  but I received:

  ORA-00932: inconsistent datatypes: expected - got CLOB
  00932. 00000 -  "inconsistent datatypes: expected %s got %s"

  I also tried many TO_ functions as well as CAST funtion - does not work.
  
  In addition, I tried

  SELECT DBMS_LOB.SUBSTR(TS_FAULT_REPORTS,DBMS_LOB.GETLENGTH(column)-2,2)  FROM table;

  but received error

  ORA-01722: invalid number
  01722. 00000 -  "invalid number"

  No idea how to solve this problem?

  Hello

  Welcome to the forum!

  So, you have a subquery which produces a string separated by commas, like ', 1074,1075,1076,1077,1078,1050,': is that correct?

  The best solution might be to change the subquery so that produce a result set with each item on a separate line. Who can actually do the subquery simpler and more effective.

  If you don't really have to use the comma-separated string, see the following links for dynamic IN-lists:
  http://tkyte.blogspot.com/2006/06/varying-in-lists.html
  http://www.Oracle-base.com/articles/Misc/DynamicInLists.php

  You coul also convert your string table number and use INSTR to see if it exists in the list:

  WHERE     INSTR ( comma_delimited_string
             , ',' || column_x || ','
             ) > 0
  

  Extra commas are to avoid the problem of 'the mother's in chemotherapy If column_x is 1 (or 0, 107, or 7, or 74 or 4) you don't want that corresponding to '1074'.
  This assumes that comma_delimited_list already begins and ends with the delimiter, as in your example. If this isn't the case, you can add them manually.

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all tables and also post the results desired from these data.
  Always tell what version of Oracle you are using.

  You will find the answers better faster if you always provide this information whenever you post a question.

• 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.

• Audting CLOB column

  Hi all

  DB version: Oracle Database 11 g Enterprise Edition Release 11.2.0.4.0 - 64 bit Production (PL/SQL Release 11.2.0.4.0 - Production)

  Brief Description: column CLOB audit until anonymous PLSQL block but does not update an external application (such as a web application).

  More in detail, we have a base with a CLOB column table and an audit table that captures any change on the base table using a trigger of DB.

  Table audit this as below:

  ID	NOT NULL NUMBER (38)
  COMPONENT_KEY	THE NUMBER OF NON-NULL
  CHANGEDCOLUMNNAME	VARCHAR2 (30)
  CHANGEDBY	VARCHAR2 (20)
  CHANGEDDATE	DATE
  BEFORECHANGE	CLOB
  EVENT	CLO

  We observe that the audit works perfectly fine if we update the prompt SQL CLOB column. But when the column is updated. a web UI - the trigger retrieves the value of

  :OLD.CLOB_COLUMN 
  

  and reads an empty clob

  :NEW.CLOB_COLUMN
  

  .

  Possible explanation: read in-depth, including that CLOB actuallly stores the reference to memory location & database manages insertions/changes effectively CLOB columns by first introducing an EMPTY_CLOB and then subsequently using DBMS_LOB. Write() for transmitting the content of CLOB to the location of the DB. DB trigger seems to be pulled between the insert EMPTY_CLOB & the DBMS_LOB. Write() and accordingly, we find that: NEW. CLOB_COLUMN to be EMPTY_CLOB.

  The above explanation makes sense? If so, why does it work correctly from the SQL prompt? Can we not check a DB trigger CLOB columns at all?

  Thank you

  Srini

  On additional debugging, it seems not to be a problem with the database. She seems to be the implementation of JDBC for CLOB data types - where it is a 2-step process

  STEP 1 - Insert EMPTY_CLOB

  STEP 2 - lock the line & enter the stream to broadcast content to CLOB CLOB.

  Given that triggers executed immediately after STEP 1 - the NEW value is EMPTY. Here, the concepts of database are intact. In this case, the check must arrive at the JDBC layer.

  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.

• 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.

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

  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.)

• Insertion XMLAgg large output in a table with a CLOB column

  Hello
  
  I need to fill a CLOB column in a table with the output of a query select using XMLAgg which returns a string length exceeds the maximum length of the SQL 32767octets.
  
  The table I ask has 300,000 lines I need to create an XML file. When I apply the query below (without XMLAgg) I get 300 000 lines that each of the 134 characters each. However, when I add the XMLAgg I can't select the results as XMLAgg concatenates my 300,000 lines in a single line, where a length of string is too long for SQL.
  
  SELECT (XMLElement ("line", XMLELEMENT ('cell', XMLATTRIBUTES ('XML_TAG_1' "colName"), attribute1)
  XMLELEMENT ('cell', XMLATTRIBUTES ('XML_TAG_2' "colName"), attribut2)
  XMLELEMENT ('cell', XMLATTRIBUTES ('XML_TAG_3' "colName"), attribut3))
  )
  of XML_TAGS_TABLE
  -Produces 300,000 lines like below
  < row > < cell colName = "XML_TAG_1" > 12345 < / cell > < cell colName = "XML_TAG_2" > abcdef < / cell > < cell colName = "XML_TAG_3" > 123xyz < / cell > < / row >
  
  With this in mind, I created a temporary table (TEMP_TAB_TEST) with a column called XML_ROW that is a CLOB. Applying XMLAgg in the above query, I would get 300,000 lines concatenated into a string. I need to get the single string output in the XML_ROW (CLOB) column XMLAgg while I can then convert them to the XML file.
  
  I don't see how I can use XMLAgg due to the length of the output it produces? Is there a way I can fill the column clob using the XMLAgg is the result of a PL/SQL package / block Anon?
  
  Thank you very much
