• Insert/update the column with the clob data type

  Hi all

  ORCL Version: 11g.

  I have a table with the clob data type.

  Test12

  (col1 clob);

  I'm trying to insert/update to update the column with more than 4000 characters.

  But due to the limitation of tank 4000, I could not Insert/Update.

  Need your help in resolving this issue.

  THX

  Rod.

  The limit of 4000 characters is incorrect.  That pertains only to the varchar2 data type.  A clob can hold more than 4 G.

  Here is an example that shows how to insert it, I found...

  Otherwise, here is a way 'dirty' to do.

  insert into your_table (COLA, COLB)

  values

  (PRIMARY_KEY, PART 1 OF DATA)

  ;

  Update your_table

  Define COLB = COLB | PART 2 OF BIG DATA

  where COLA = PRIMARY_KEY;

  Update your_table

  Define COLB = COLB | PART 3 OF BIG DATA

  where COLA = PRIMARY_KEY;

  .. and so on...

  I don't know that I personally recommend the second style...  But he could do the job.

• Problem with the CLOB data type.

  Greetings,
  
  I am facing a problem with the CLOB data type. I know that the CLOB data type is 4 GB (I use Oracle 9i). But in the Pl Sql procedure, I can only store 34305 size for a CLOB variable character data.
  
  This is the test script that I am trying to run.
  
  DECLARE
  -Local variables here*.
  I have INTEGER;
  C_1 CLOB.
  BEGIN
  FOR Rec IN (SELECT
  *
  ACCORDING TO THE TABLE)
  LOOP
  C_1: = c_1 | Rec.Clo_1;
  END LOOP;
  EXCEPTION
  WHILE OTHERS THEN
  Dbms_Output.put_line (SQLERRM);
  END;
  
  
  Here variable C_1 range value 34305 good character regardless of type CLOB. Now the above script fails if query my buckle - huge number of return values. It is throwing the exception "error during transfer of files ORA-06502: PL/SQL: digital error or value."
  
  He would be grateful if someone can help me on this.
  
  Thank you.

  You are probably better off using DBMS_LOB.append, instead of the concatenation of varchar2 (|).

• DLL for LabWindows/CVI 8.0 with the bool data type

  Hello

  I want to use a new SWIR camera in LabWindows/CVI 8.0 (Windows XP 32bits).

  The company delivered with the camera produced a 32-bit dll by using Microsoft Visual C++ 2010. The .dll and .lib and .h files include a working SDK/API (some functions with the bool data type)

  Compilation-online syntax error, variable Boolean is not a data type in LabWindows/CVI 8.0

  Generate the import of DLL-online syntax error library

  I tried to convert bool char (typedef unsigned char bool => no more syntax error but the functions does not work.)

  What can I do?

  Martin

  Hello again, Naumann!

  Microsoft Visual C++ 2010 represents Boolean using 1 byte, as stated by MSDN: https://msdn.microsoft.com/en-us/library/tf4dy80a(v=vs.100).aspx

  I guess that you import C++ functions using the syntax for extern "C". Otherwise, because of the C++ name mangling wouldn't you able to bind C++ library against your code CVI.

  You can also specify how you import C++ functions?

  In addition, because you have not described the problem as a corruption of heads or runtime error, I guess the C++ library function is called correctly the CVI. That said, I tend to believe that the problem is not really in the mechanism of interaction of C/C++, but in the C++ library. If you would start calling a dummy C++ function returning an integer from a simple CVI application that should work, because redefine bool in CVI 1 byte must ensure that settings are correctly transferred onto the stack.

  If you need to create a wrapper function of C++ that is not using bool and calls the C++ function, I expect to return the same result.

  Maybe you are missing a few prior initialization steps required? The provider of the camera also comes all example code?

  Best regards!

• How the parameter of the procedure with the default table type?

  Hello!
  
  How the parameter of the procedure with the default table type?
  For example:

  type varchar2lType is table of varchar2(50) index by binary_integer;

  create or replace procedure test1

  Published by: bullbil on 16.01.2012 06:35

  If he should really be an associative array for some reason any (can't think why, but just for fun...) you could declare a dummy array in the packet header and specify as the default:

  create or replace package wr_test
  as
     type varchar2ltype is table of varchar2(50) index by pls_integer;
     g_dflt_varchar2l_tab varchar2ltype;
  
     procedure testit
        ( p_testarray varchar2ltype default g_dflt_varchar2l_tab );
  end wr_test;
  
  create or replace package body wr_test
  as
     procedure testit
        ( p_testarray varchar2ltype default g_dflt_varchar2l_tab )
     is
     begin
        dbms_output.put_line('p_testarray contains ' || p_testarray.count || ' elements');
     end testit;
  
  end wr_test;
  

  It is a bit of a hack, because it relies on a global variable that is exposed. A more orderly approach would overload the procedure so that a version does not have the table and another argument:

  create or replace package wr_test
  as
     type varchar2ltype is table of varchar2(50) index by pls_integer;
  
     procedure testit;
  
     procedure testit
        ( p_testarray varchar2ltype );
  
  end wr_test;
  
  create or replace package body wr_test
  as
  
     procedure testit
     is
        v_default_array varchar2ltype;
     begin
        testit(v_default_array);
     end testit;
  
     procedure testit
        ( p_testarray varchar2ltype )
     is
     begin
        dbms_output.put_line('p_testarray contains ' || p_testarray.count || ' elements');
     end testit;
  
  end wr_test;
  

• Using DBMS_DATAPUMP with the LONG data type

  I have a procedure below that calls the DBMS_DATAPUMP procedure using a REMOTE_LINK move a schema of one database to another. However, some tables in this schema have columns with the data type of LONG. And when I run it I get an error saying that you cannot move the data with the LONG data type using a REMOTE CONNECTION. So no data in these specific tables gets flying over.

• How to use the node function call library for a function in the dll with the data SUB type

  Hi all

  I would ask for your kind help

  I am facing a problem with the call library node.

  I have a C++ (stdcall) function, which has Sub as data type

  XXXX error code (hwnd, lid, getValue, * Sub data1, * Sub data2)

  data1 and data2 types are constantly changing based on the value of 'getValue '.

  Mainly I can use the call library node several times and adapt each node according to the types of data data1, data2 and extract the values and use in the code. Here is no question. Real question is:

  My question:

  How can I use a node of library time call and make a case according to the 'getvalue', who will control the data1, data2 data type. Here I really seeking solutions.

  My tests:

  I used varaints as entry to the libray call node of the data1, data2 and selected parameters in the call libraby node as "Adapt to type. Here labview just crashed.

  I appreciate your suggestions to feedbackand.

  Thank you

  Karine

  You must allocate enough space for data1 and data2, and then pass a pointer to this space. An easy way to do this is the function to initialize table. Set the U8 type and size for the number of bytes required. Pass this array to the function as a pointer of table data.

  After the function call returns, you need to extract the data in the table. You can do it manually, but a simple approach is to use the array of bytes to a string. Then, in a housing structure, use Unflatten chain to convert the string to the correct data type. This method also converts the "endianness" which will be probably necessary; Be sure to only set all entries for unflatten correctly.

  It does not make sense to try to build a literal string that represents the binary data in a GIF file and that insert a BLOB using an INSERT... Statement of VALUES.

  You can use the first approach (dbms_lob.loadfromfile) to load a GIF file (or any file) into a BLOB.
  If the image you are trying to load is not a file on the filesystem of database, you can use SQL * Loader on the client machine to load the data, or you can write an application in any language you want that reads the data from the file and inserts it into the BLOB by using the API in your language / framework. You have not told us what language and framework you use, but it shouldn't be too hard to find a suitable example. For example, if you use Java and JDBC, here is an example of loading a GIF in a table.

• Problems with the Long data type conversion

  With the help of Oracle 11 G.
  
  I have a vision where one of the name of the column is of type long, I need to convert in varchar2. I tried using the to_Lob() function, but this error:
  
  ORA-00932: inconsistent data types: expected - got LONG
  
  I followed this article (step 1), which suggests to use to_lob()
  
  My query is:
  

  select
  item1, -- this is of type LONG
  item_vat, 
  price_pc_tot,
  from xd_item_price_view 

  I tried to convert it into:
  

  select
  to_lob(item1) as item1_x, -- this is of type LONG
  item_vat, 
  price_pc_tot,
  from xd_item_price_view 

  I am confused about the "-", why he would expect that? Thanks for watching it.

• Cannot save the types of collection with the correct data type (structure type)

  Hi all!
  
  I am beginner in using the Data Modeler (SQL Develeoper Version 3.0.04 build HAND - 04.34)
  
  I tried to define types of structured data type type collection.
  
  for example
  Types of structure: StruA (for example, Integer, Float) and StruB (e. g. whole, Timestamp, Double, Double)
  Types of collections: TabA should collect the types of StruA and TabB should collect the types of StruB.
  
  create or replace TYPE TabA IS TABLE OF StruA;
  create or replace TYPE TabB IS TABLE OF StruB;
  
  It is possible to select the correct data type in the 'Collection Type properties' dialog box.
  
  The data type is installed to unknown after the registration and the reopening of the design. I see that the correct type has been entered in the xml file associated with the type of collection:
  < dataTypeDescr class = "oracle.dbtools.crest.model.design.datatypes.CollectionType$ DataTypeWrapper" >
  65677BBB-FB68-963C-552D-3F98E528520B < type > < / type >

  File name of the structured type is 65677BBB-FB68-963C-552D-3F98E528520B.xml
  
  On the display of the design or generation DDL lose again this information.
  Is - this poor handling or a bug in the Data Modeler?
  Can anyone help? THX

• confusion with the categories and types of backups

  Hello
  
  I started studying the RMAN and I'm getting a little confused with the backups... ask someone to clarify the following queries:
  
  1. HOT times and COLD backup strategies perform BACKUPSET BACKUP and COPY of the IMAGE?
  
  2 about the HOT water and COLD backup, are they only associated with the FULL backup?
  
  3. incremental backup are also HOT or COLD backup?
  
  4. incremental has 2 types: Cumilative and differentiated?
  
  
  I'm a bit confused with the above...
  
  Help, please.
  
  Concerning
  KK

  Whether HOT or COLD:
  BACKUP DATABASE will create BACKUPSETs

  (this default value can be overridden if you have set up the TYPE of DEVICE...) BACKUP TYPE to... where the backup type can be changed by default for the COPY.

  Whether HOT or COLD:
  DATABASE BACKUP AS COPY will create Copies of the Image

  An incremental backup can be a HOT or a COLD backup.

  This makes large, however submit that it seems that the checksum of line used by MRU included the raw HTML generated by the APEX_ITEM package and not just the value of the column. I worked around this by including an element hidden checksum and creating a process that replaces the checksum generated automatically with my custom.
  
  Is there a better way to intercept this checksum, preferably before it is rendered on the page? I now hide the sum of hidden HTML control in the output HTML of another column, so it's a bit ugly. If not, is there an easier way to achieve what I'm looking for? I tried several combinations, and it seems to work better. It's just a shame there's no way to have a standard hidden column included in the SRM process.

  Hello

  I tried different possibilities and seems to run the following:

  Create a report questioning in NORMAL SQL function to help:

  SELECT
  APEX_ITEM.HIDDEN(1,EMPNO) || APEX_ITEM.TEXT(2,ENAME) ename,
  CASE WHEN DEPTNO = 10 THEN
   APEX_ITEM.HIDDEN(3, SAL) || SAL
  ELSE
   APEX_ITEM.TEXT(3, SAL)
  END SAL,
  EMPNO,
  DEPTNO || APEX_ITEM.MD5_CHECKSUM(ENAME, SAL) DETPNO
  FROM EMP
  

  Do not specify something special for column definitions.

  Create a button that submits the page.

  Create a PL/SQL process that runs "On submit - after calculations" and Validations, triggered by this button and using the following code:

  BEGIN
  APEX_ITEM.MULTI_ROW_UPDATE('#OWNER#:EMP:EMPNO,1:,|ENAME,2:SAL,3');
  END;
  

  I've done here: http://htmldb.oracle.com/pls/otn/f?p=55041:35

  Any element with the value of DEPTNO 10 has the value SAL, read-only, as otherwise it's editable. This is done by creating a hidden input field for the actual value, followed by the text version OR by creating a single entry field. This ensures that we have the correct number of SAL elements on the page.

  APEX_ITEM. MULTI_ROW_UPDATE is the "manual" version of the MRU that you would normally get with a form of table and works for above normal as sql based query reports. The format of this very strict is that you must always allow for two primary keys. See the text of presentation here: http://download.oracle.com/docs/cd/B28359_01/appdev.111/b32258/api.htm#CHDFDACC
