• Oracle DW and necessity of date type.

  Vast majority of designing data warehouses use the granularity of the fact to the date level table. In oracle, you can use only the data type of date (which is not really date rather datatime) to represent the date in truncating the time part of it.
  But it allocates even 7 bytes for headaches from it. One of the competitions of this Oracle the true DATE type that takes just 3 bytes to store the value of type date. You can imagine how much storage space you can save using 3 bytes instead of 7 paintings done great. I think that Oracle needs to come with a similar option soon. It will help a lot in performance and the use of disk space.

  Not really relevant to this forum. The title of the forum clearly States ' * + don't post Product - Related Questions here + * ".

  As to the question that you raised - RDBMS Oracle supports advance user-defined data types. You can easily implement a data byte 3 type date personalized if you wish.

• VLD-2550 and 2551: CLOB data type errors

  Hi all
  
  I tried to solve thi sproblem, but have not been able to find a solution.
  Basically I have a Col1 (of A table) of the clob data type that is to be mapped to Col2 (table B).
  But when I validate the card I get the error:
  
  VLD-2550: BLOB, CLOB or NBLOB of the remote source data cannot be transformations (control Details: If you have any CLOB, BLOB as a remote data source, it must be directly mapped to a target feature)
  and
  VLD-2551: BLOB LCOB or NBLOB remote data source must be set based ON a SET of generation mode.
  
  My card has a mapping one between the passes of the tables A and B. Col1 is directly related to Col2 (if that is what is meant by any of the transformations of type CLOb)
  
  Thank you very much

  Hello

  If your source table (which the CLOB) is in the remote computer then you must set the mapping mode basic SET and you need to connect directly the source column of the target column.

  If you still get this kind of validation waring and simple not then ignore them.
  This is a defect of OWB. See Bug 5989066 : card VALIDATION WITH BLOB OBJECTS JETTÉ VLD-2550 AND VLD-2551 WARNINGS, which has yet to be fixed.

• 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.

• XQuery and relational queries with the RAW data

  Is it possible to leave the XQuery to use the RAW data type (16) without casting?

  KnightOfBlueArmor wrote:

  You are overloading the things, no need to XQuery Update in this case.
  As far as I understand it, all you need is XMLAgg:

  SELECT e.book_id
       , e.title_txt
       , e.subj_txt
       , XMLElement("inventory"
         , XMLAttributes('http://www.mrbook.com/InventoryData' as "xmlns")
         , XMLAgg( b.book_data )
         ) as inv_data
  FROM entity e
       LEFT OUTER JOIN book_frag b
                    ON b.book_id = e.book_id
  WHERE e.title_txt = 'Finite Variable Analysis'
     OR e.subj_txt = 'Finite Mathematics'
  GROUP BY e.book_id
         , e.title_txt
         , e.subj_txt
  ;
  

  (the OUTER JOIN may or may not be necessary, depending on the relationship between the two tables)

• Simulink Inport/Outport data types

  I searched for a while and I am unable to find documentation about what types of data I need to use the inports, outport, settings and in my Simulink models.

  Is there some specific types of data that are, or are not supported?  How VeriStand to determine how to coerce data to send the model?  Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  Any clarification would be much appreciated.

  VeriStand 2013 SP1 (probably upgraded to 2016 in next year if it's relevant)

  MATLAB 2010 b and MATLAB 2012 b (currently)

  > Are there types of specific data that are, or are not supported?

  I don't remember there being any limitation of types beyond what is stated in the considerations help document.

  Considerations relating to the integration of The MathWorks, Inc. Simulink® software models (model Interface T...

  The big hiccup I remember wasn't mainly with types of configurations and data bus.

  IIRC, you can choose any numeric type desired in Simulink. The structure of the model interface that uses VeriStand will handle any type and convert it to double so that it can be consumed by the VeriStand engine.

  > How VeriStand to determine how to coerce data to send the model?

  I think the way it works is that when VeriStand interacts with the Simulink model, it gets a list and information (pointer, data type) of inports, remote villages and settings. Thus, it can capture data from the model (because it has the pointer), and it can cast its data type (because he knows the type) duplicate. If you look at the example model model interface on line 212 it might help to make things more clear on how this could work.

  C:\VeriStand\2016\ModelInterface\custom\examples\template.c

  Double USER_GetValueByDataType (void * ptr, int32_t subindex, int32_t type)
  
  {
  
  	switch (type)
  
  	{
  
  		case 0:
  
  		{
  
  			/ * double * /.
  
  			(double) return (((double *) ptr) [subindex]);
  
  		}
  
  		case 1:
  
  		{
  
  			/ * only * /.
  
  			(double) return (((float *) ptr) [subindex]);
  
  		}
  
    	}
  
  / * return NaN, ok for vxworks and pharlap * /.
  
  	uint32_t nan [2] = {0xFFFFFFFF, 0xFFFFFFFF};
  
  	return *(double*) nan;
  
  }

  I'm guessing that the full implementation of which uses VeriStand is much more complex, but I think that the idea is the same.

  > Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  VeriStand engine uses indeed of all double rooms.

  You happen to remember this post and you can share the link? I'd be curious to see where this is said and in what context.

• How can I dynamically select the shared Variable API programming data type?

  I am trying to create a configuration of open connections of variable shared using the programming API. It seems to me that the cleanest way to do would be to put one "open and check" routine in a loop, then call it for each variable in the library.

  The question that I am running is that I have different types of data in my library (to help a server Modbus i/o and data types 'boolean' and 'single' in my library.) How can I dynamically select the data type of the shared variable API?

  See the attached snipit.

  Thank you

  What I ended up doing was doing a Subvi to open, read, write, and close each data type, I use the packaged in 4 polymorphic SubVIs (polymorphic Open, read, etc...)

  Now all I have to do I drop in the polymorphic Subvi and it switches automatically to the appropriate data type

• Import SQL Developer data change column entire varchar data type

  Hi all
  
  May I ask, how do to change all the data type of columns using a single click? I want to import a csv file that has more columns then 200. When I use SQL Developer to impoprt it to the Oracle database, there is the possibility to change the data type of the columns, but it is posibble only on a column-by-column. How can I do this with just a click of mouse? In the csv file, there are only numbers, not alphabetic or other characters. But SQL Developer sets automaticully VarChar for all columns when importing the csv file. And if the data type of the columns is of type varChar, the data mining model produced only 10% of predictive confidence. If the columns integer (number), the trust is more than 80%. I use about 50 tables, and each table has more than 200 columns, so changing the data type of columns by a something inhuman is ::(((
  I saved the csv as xlsx file, but when I tried to import it with SQL Developer, I chose this xlsx and Developer SQL closed the import window. If I can't import xlsx...
  
  Can someone help me?
  
  Thank you!!!

  You can send the generated here script? I just want to see the DDL Create of the Table and some examples of INSERT statements.

  To remove the rows in the Table, you can run this in the worksheet:

  DELETE

  ;
  COMMIT;

  You can run the Create Table DDL (skip all INSERT queries) to create the table. Then, use the Import Wizard to import data in this table (column all should have correct data types). In the Import Wizard, you can specify the Table to import the data.

• How to insert a column of type long raw

  Hi all
  
  I'm trying to copy a record with a column of type long raw.
  But it raises an error ORA-00997: illegal use of the long data type.
  
  For example, the HR employee table: PER_IMAGES
  
  INSERT INTO per_images (image_id, parent_id, table_name, image)
  SELECT 21,10, 'test', images OF per_images WHERE the image_id = 2
  
  It triggers ORA-00997: illegal use of the long data type.
  
  It cannot be resolved by the statement "copy of" ("copy of" only works for the LONG data type, not LONG RAW datatype)
  
  We try to export the data in long-raw format source to the BLOB data type.
  And then insert BLOB of long-crude recording of destination.
  (i.e. long-raw > > to_lob(long-raw) > > BLOB > > long-crude oil)
  It works without any error message, but there are empty picture in the destination folder.
  
  Is there a function of BOLB in LONGRAW data conversion system?
  
  Our version of the database is 9i.
  
  
  Any suggestion will be appreciated.
