  correct syntax is
  ALTER TABLE.

  MOVE the LOB ()
  STORE AS (tablespace );

  Where is a name of the / columns LOB, not the name of the segment. Moving type LOB data will move its indexes as well.

• Impact on performance when you use the LONG data type

  Hi all
  
  
  Only I have a doubt about the use of LONG data type
  
  I use the data type LONG for some columns in a table and I created indexes on the columns separately, but these column values can be easily fit into the varchar data type.
  
  (Just to see the performance on this issue)
  
  Suppose that a common select query with WHERE condition on any of the column which has LONG data type will affect the performance of the query?
  
  Please explain.
  
  Thank you

  (1) the LONG (and LONG RAW) data types have been depricated for quite a while. Oracle has been strongly recommends that you move to 8.1.5 CLOB and BLOB data types. Why you use the LONG data type? You're still on Oracle 7?

  (2) have you tried to write a query that has a WHERE condition that refers to a LONG column? In general, you can not because it does not support the type of data LONG. For example

  SQL> ed
  Wrote file afiedt.buf
  
    1  create table a (
    2    col1 varchar2(30),
    3    col2 long
    4* )
  SQL> /
  
  Table created.
  
  SQL> select * from a where col2='abc';
  select * from a where col2='abc'
                        *
  ERROR at line 1:
  ORA-00997: illegal use of LONG datatype
  

  LONG data types are a royal pain to work with. They also have implications on the performance of wicked on the client.

• How to use the queue data Structures stack?

  Hi all, you can tell me how to use the queue, stack, the link in the list... Structures of data in the project of BlackBerry? Thanks for any suggestions!

  BlackBerry devices are not java desktop running. you are limited to the blackberry api, basically j2me + rim extensions, based on java 1.3/1.4 (no enums, no generic, many collections not impl etc.).

  Remove your JRE6 and change your code until there is no more error.

• How to use the tracking data?

  I created a Web page, add the tracking inside scripts. Based on the history tour of the visitor I want to perform certain actions or to put ads on the PURL page accordingly. But I can't find the data that has been the subject of a follow-up or where does the tracked data is stored?

  Hi assani

  Case of use which you are referring. Theoretically speaking, we could accomplish this type then:

  -Decision program rule evaluates the membership contact filter. Contact filter uses the comparison of capture all contacts who have visited the Web site activity-based x.

  -If the contact is rated as 'Yes', run an update rule to force a specific value in a field of contact (for example, if the contact has visited the site, then leave the field "has visited the website?" = "yes")

  -Insert the dynamic content on the PURL page that displays according to the value in this field of specific contact (for example, if 'yes' then display ad, if you see 'no' then ad Z)

  Note: the 'extra' step to push the value in a field of contact is necessary because the contained substitution works based on contact (or company or prospect) field values

  I don't know that too, there are other ideas out there. Would love to hear them.

• convert the varchar2 data type to the data number type

  How to convert the varchar2 data type to the data type number.
  
  
  It looks like my data
  
  create table one)
  col1 varchar2 (50)
  col2 varchar2 (500);
  
  Insert in a (col1, col2) values ('1234 ', ' 2345');
  
  Select Column1 of number (19)) cast (to_number (col1);

  I need to create a table with the same columns with data like number types (19)
  
  can someone help me
  
  Thank you

  You have changed your original post, so now I see that you get the invalid number.

  This is why you should always avoid the varchar columns to store numbers or dates...

  Since your table source contains a nonnumeric value, you can write a pl/sql to convert data and see what records are false:

  SQL> insert into a (col1,col2) values ('xxxx','2345');
  
  1 row created.
  
  SQL> select * from a;
  
  COL1     COL2
  -------- --------
  1234     2345
  xxxx     2345
  
  2 rows selected.
  
  SQL> create table b (col1 number(19), col2 number(19));
  
  Table created.
  
  SQL> set serverout on
  
  SQL> declare
    2  cursor c is
    3  select * from a;
    4  begin
    5    for r in c loop
    6     begin
    7       insert into b values (to_number(r.col1), to_number(r.col2));
    8     exception
    9       when invalid_number then
   10        dbms_output.put_line('Row rejected: col1='||r.col1||' col2='||r.col2);
   11     end;
   12    end loop;
   13  end;
   14  /
  Row rejected: col1=xxxx col2=2345
  
  PL/SQL procedure successfully completed.
  
  SQL> select * from b;
  
        COL1       COL2

• What the best data type for storing jpeg/gif images?

  Hello
  What the best data type for storing jpeg/gif images?
  Idon't want to use the blob data type
  Ordimage is the best?
  Thank you.

  VDH says:

  What the best data type for storing jpeg/gif images?

  Ordimage is the best?

  Don't be stupid.

  If you do not want to use BLOBs then, or you can use the ordimage.

  It uses ordsys.ordsource for the storage of the image data type. This is a user defined Type of data in advance and has a property called LocalData that stores the actual image. And what is its data type? BLOB OBJECT.

• 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.

• For the complex data type, how to generate the Dll with compatible interface to C/C++

  Hello

  I used the Labview FPGA module to develop test equipment. Now, I need to write a driver that is to be a Dll with compatible interface to C/C++ for this equipment. So that my client who is familiar with C/C++ can call the driver without any study on labview. But I had a few problem on how to convert labview for C/C++ data complex data type. To clearly explain to my question, I have attached a simple example. (see attachment) I try to generate a Dll for the attached example VI and get the the function prototype at the head of the files as below:

  ' void OpenFpgaReference (LStrHandle * RIODevice, TD1 * errorIn, LVRefNum * FPGAVIReferenceOut, TD1 * errorOut).

  As you have known, the type of data "LStrHandle * RIODevice" and "LVRefNum * FPGAVIReferenceOut" Labview data format are. C/C++ do not have this kind of data type and can not reconige it. As a result, I can't call the Dll of C/C++ programming language. How to convert these two data type of labview for the C/C++ compatible data format, and then build the Dll? Anyone know about this?

  The answer is really apprecaited! Thank you in advanced.

  As I found in the following article:

  http://digital.NI.com/public.nsf/WebSearch/FB001AA027C8998386256AAD006C142D?OpenDocument

  LVRefNum is the name of resource of LabVIEW VISA or refnum, and "it is impossible to convert LabVIEW VISA name of resource or refnum VISession valid ID."
  This means that external code modules can not access & control the session VISA which is open by labview. But for my purposes, I will not attempt to access this VISA extenal code(C/C++) session. I just hope that save this session VISA in the external code once I opened it in Labview dll; and pass it to the labview dll when needed. While I have not need to login again when I need to control the device. Is it possible to do?

  A LVRefNum is really just a single int32 value. Its meaning is useless for other environments than those who created it so that you Michael not any what in C/C++ caller but pass it back to other functions in your DLL, but this often isn't a problem at all.

  You can take the following statement of the LabVIEW extcode.h headers and add them to your delabviewed header files to make it work in such a way.

  #define Private (T) typedef struct T # _t {void * p ;} * T}

  Private (LVRefNum);

  The LStrHandle you must set a standard C string instead in your export DLL and document what is the size of the string buffer should have if it is an output parameter.

  TD1 error clusters should also be divided into their parameters (C compatible) separate for all items or just to the left of suite entirely.

  This is what happens when you copy a code without understanding.
  Take a look at the code here

  /* Writing the BLOB in chunks */
  WHILE l_pos < l_blob_len LOOP
  DBMS_LOB.READ(l_blob, l_amount, l_pos, l_buffer);
  UTL_SMTP.write_raw_data(v_connection_handle,
  UTL_ENCODE.BASE64_ENCODE(l_buffer));
  UTL_SMTP.WRITE_DATA(v_connection_handle, UTL_TCP.CRLF);
  l_buffer := NULL;
  l_pos := l_pos + l_amount;
  END LOOP;
  

  Discover the parameters of DBMS_LOB. READ.
  For the first time it's good reading but your position and the quantity is not initialized when you loop and read again and is not read correctly.
