• 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!

• 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.
  
  Does anyone else have this problem? If so, do you have a work around? I tried to add a CLOB column in my table and affecting the new CLOB equal THROUGHOUT, but I couldn't get that to not work either... even when I tried to use a TO_LOB. If I could get that pass, then I could just slide ALONG, the schema, and then re-create the LONG column on the opposite side.

• 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.

• Syntex to create the table with the long data type

  I'm looking to create a table based on another table that having the column long data type. Throw the error ORA-00997: illegal use of the LONG data type

  How to get there?

  I'm looking to create a table based on another table that having the column long data type.

  You really don't want to do that.

  LONG data type has been deprecated for some time now, use CLOB.

  The TO_LOB() function will do the conversion on the fly:

  create table abc_long_dummy
  as
  select ag
       , to_lob(bgd) as bgd
  from abc_long ;
  

• 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 >
  false < isreference > < / isreference >
  < / dataTypeDescr >
  
  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

• match the number with the varchar data type

  Hi all
  
  I want to compare the number data type with string. Is this possible? I use the function to_char. The example below.
  

  SQL> select * from tab_a;
   
   PLOT_NUMBER
  ------------
             1
             2
             3
             4
             5
             6
   
  6 rows selected

  SQL> select * from tab_b;
   
  PLOT_NAME       PLOT_NUMBER
  --------------- ------------
  seawods         5
  bridge cros     2,4
  hill park       1
  bash hunk       3,6

   
  SQL> select a.*, b.* from tab_a a, tab_b b where to_char(a.plot_number)=b.plot_number;
   
   PLOT_NUMBER PLOT_NAME       PLOT_NUMBER
  ------------ --------------- ------------
             1 hill park       1
             5 seawods         5

  as you can see here this number of parcel 2, 4, and plot_number 3.6 not reported because they are string.
  
  Can anyone please suggest what can do us in this case.
  
  I can't do chane data type.
  
  Thanks in advance
  SAZ

  What you can do in the case?

  Drop table table_b purge

  as the 'design' of this table is obviously out of whack, and the content should have been

  PLOT_NAME       PLOT_NUMBER
  --------------- ------------
  seawods         5
  bridge cros     2
  bridge cros     4
  hill park       1
  bash hunk       3
  bash hunk       6
  

  You now have the instr function to the "join".
  I would recommend standardization of the design. NOW

  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.

  >
  Sorry mate, just realized that. Yep, this is the one I followed (step 1 using to_lob())

  It's a case of 'use' along in a query or search.

  But you can use to_lob as part of creating a new table.

  According to the 423858.1, it of the problem with the JDBC driver that reverse engineers and takes the default as 22. To work around the problem, you will need to use Oracle RKM to customize boning them

• Bad high and low value with the varchar2 data type

  Hello
  
  It is an application on e - biz on database 9205, with inventory module.
  
  In one of the mtl_txn_request_headers of the table, the data for the number of application type is varchar2 (30). When I checked the low_value & high_value in dab_tab_columns, I see that the low_value is 100001 (6 digits) and high_value is 99999 (5 digits).
  
  I used the utl_raw.cast_to_varchar2 (low_value) to convert the value.
  
  In our case, we save a large part of the value in incremental number and some of our query will be in the predicate of the range (between).
  
  How should I handle this kind of situation and which option do I?
  
  Appreciate any help. Thank you.

  Accepted this looks like a classic bad-data type problem, but as this picture seems be part of Oracle E-Business Suite the OP should probably talk first Oracle.

• Problem with the percentage data type

  Hello
  
  I understand that if a member account data type is percentage, then the corresponding value in the form of data is displayed as a percentage. For example, if I need to get 50% against the particular account member, then I can type either 0.5 or 50%. But is there the parameters by which if I hit 50, system will consider as 50%, not 5 000%.
  
  Thank you.

  You can type either 0.5 or 50%
