• How to get user defined Native Types is displayed

  I added a new user defined native Type using type Admin

  

  I saved, closed and then reopened the Data Modeler, but he does not appear in the Source Type drop-down list when I define a column in the relational model. I've defined the relational model to use 12 c as the Site of RDBMS. Am I missing a step in the installer?

  I use 4.1.3 on a Mac.

  Hello Kent,

  the native DB types never appear in the column definition. You need to create the new type of logical data and map it to the native type or change the mapping of logical type existing. The steps are confusing because it's like the problem or chicken (which is the first), you you will be defined first:

  (1) define the native type - save definitions - defined by the user of the native types had to be saved in order to be available for native types logic mapping

  (2) identify the type of logic - probably VARIANT in your case, define the mapping of native type logic

  (3) in native type definition define the mapping of native code to the logical type (it is mapped on the CLOB type on your photo - probably you will change it)

  (4) save the definitions

  MY QUESTION IS: type_name, record_type must be the same?

  It is not necessary to be the same. Once you create a record type, then it might be assigned to different variables, such as:

  SQL > DECLARE

  2 C_cr CURSOR IS

  3. Select ename, equality, esalary, eid, ecity emp;

  4 TYPE EMP_DETAILS IS RECORD

  5 (e_id emp.eid%TYPE,

  6 e_name emp.ename%TYPE,

  7 e_qual emp.equal%TYPE,

  8 e_salary emp.esalary%TYPE,

  e_city 9 emp.ecity%TYPE);

  10 emp_detail EMP_DETAILS;

  11 emp_detail_2 EMP_DETAILS;

  12 emp_detail_3 EMP_DETAILS;

  13 l_id NUMBER;

  
  

  Now, he becomes similar to a variable_type of variable_name in the declaration section. Emp_detail or emp_detail_2 is a variable of type EMP_DETAILS, like the variable l_id that can hold values of type numbers.

• Querying the user-defined types

  I have a chart in which one of the columns is a user-defined data type:

  SQL> describe my_table
  ...
  USER_DATA    MYTYPE

  The type 'MYTYPE' is a simple object that contains a field: a CLOB called MESSAGE:

  SQL> describe mytype
  Name       Null?    Type
  ------     -----    ----
  MESSAGE          CLOB

  When I do a "select *...» "in this table, the USER_DATA column appears as"MYTYPE (oracle.sql.CLOB@898c2d).
  
  I know that for CLOB and BLOB fields, Developer SQL let me double click on the value and display the content. But for type like this defined by the user that contains a field, I can't navigate the data members of type. I find myself wanting to do something like a 'select user_data.message from my_table", but this is not a valid syntax. Is there a way to query a given specific member of this type defined by the user with the rest of the columns in the table, I can display the CLOB member instead of a representation of the object? If not, is it possible to configure SQL Developer to allow me to browse the data members of types defined by the user? TOAD has a feature like that but I would only use SQL Developer and it is a table that I work with on a regular basis.

  csimons,

  Try this:

  select  t1.user_data.message
  from    eimgr.aq_rtv_docs_out_table t1
  where   rownum = 1;

• Use of user defined function in mathscript containing a structure

  Hi, I am a novice user of LabView MathScript module,

  I have the following problem when integrating my code MATLAB, LabView, for HMM: in my program, I tried to call a MATLAB called "mixgaussinit.m" user-defined function, it shows this error...

  "

  I just noticed that these files appear to be copyrighted. My first question is do you have author permissions to post them in a public forum? If this isn't the case, then you can remove them. That being said, I have reviewed the code and it seems easy enough to work around your problems (provided that you have the copyright permissions). How to bypass the problems is to replace the fields of the struct with variables. There is of course allows you to change some definitions of functions for input and output the necessary variables which I think was the best 5 variables. You will also need to redo the code that uses a table of error checking cell. In total, I estimated about 30 minutes of work. I would have given you work around these files had not been protected by copyright. So, unfortunately, you will need to implement the work around you.

• variables of user-defined data transfer

  Hello

  I use the etherCAT 9144 chassis and is only supported by this hardware FIFO range target. After a search, I realized that the only way to transfer data from FPGA to the host by using user-defined variables. But these variables do not support the notion of FIFO. So which is the best practice to transfer data after measures (provable 10 Hz measurement of 15 values) to host VI?

  Thank you

  As mentioned, the 9144 only supports the analytical engine.

  In regards to what you do, it really depends on the entire application. For example, what is the master? Are there other systems at issue here? Etc. It's a good read, in general, although it might not help this second right: http://www.ni.com/white-paper/14151/en/

  A high level, you need to decide what you need. If you have need for deterministic communication, low-latency over long distances from a RT controller, the 9144 is probably the right choice. If you need low latency + streaming over short distances to a RT controller, you should look into the RIO MXI chassis. If you need mainly not deterministic low speed (10 hz) data mixed with low flow continuous over long distances to a windows or host RT, then ethernet expansion rio (9146,7,8,9) is probably the right choice. If you need high speed continuous with low control latency over long distances to a windows or RT host, you need a full cRIO controller. Based on what you've posted so far, its uncertain is the right person.

  Lets say you're stuck with the 9144 for now. As you can easily hit 1 kHz scanning cycles, it should be perfectly possible to data 'stream' to 10 Hz. If you run the scan at 1 kHz engine, then you are 100 x oversampling. Where it gets complicated is this requirement of sync. By default, acquisition input/output is synchronized to the clock of the scan (and you can see when the clock of scan is set by a knot of e/s FPGA). However, you can take complete control of a module in the FPGA and read inputs and outputs at any time if you please. In other words, you can set up so when DIO0 goes high you immediately enjoy all the values of AI 15. You can then transfer these values HAVE switched to the host using the user-defined variables.

  Your question is quite broad and fuzzy then I suggest the security catalog presentation to read documentation: http://docs.oracle.com/middleware/1221/biee/BIESC/mgrgrpsusers.htm#CIHIBJGD

  And I think that you mix you two things which are managed in different places:

  ) an object as read access permissions, write, delete... which control you through the object "Permissions" dialog box

  

  

  (b) functional privileges controlled through "Manage privileges" under "Administration".

  

• Extracts & user defined Variables

  After ~ 5 years not working not with any what HAT, I started a new post on 28/03/2016 and put back the trial HR 2015 a spin. I'm very excited by what I see and were able to do so far.

  I have 3 'entities' to write and I created 3 pages, one page per entity.

  Each of these presentation pages, I have this first line:

  |

  This section describes how to enter and manage [entity].

  |

  I set each [entity] as a user-defined variable. Each page with this sentence I hard-coded and added a reference to the user defined Variable and then produced output. Works great.

  Now, I'm going 'down' a level. What I want to know is how to

  |

  "This section describes how enter and manage."

  |

  be a code snippet. I want it to be an excerpt because when I write a sentence better, I don't have to make the same change on each of these presentation pages. Finally, there are 19 pages of presentation.

  
  

  Anyone who structure their content like this?

  
  

  What I want to avoid doing several manual changes. For example, if the following examples have been in a RoboHelp project, on https://support.assessment.pearson.com/x/N4Dy, there is this sentence:

  
  

  This section shows you how to manage user accounts.

  
  

  On this page - support to manage test paper - next to PearsonAccess online User Guide - Pearson Assessment - it is this sentence:

  
  

  This section covers all the unique aspects of the test paper.

  
  

  What I'm trying to do, is to have an extract which is defined as:

  
  

  This section tells you how to

  
  

  and refer to it on both pages.

  On the first page, it looks like

  from <>this section tells you how to< / endSnippet >

  user accounts < beginUserDefinedVariable >< / endUserDefinedVariable >.

  Then on the second page, I would say this:

  extract < code > This section tells you how to < / endSnippet >

  < beginUserDefinedVariable > manage paper test < / endUserDefinedVariable >.

  |

  The reason why I want it as a snippet of code is because I don't want to have to maintain "this section tells you how to" text hardcoded on each of these presentation pages. I would like to take advantage of the functionality of content reuse to avoid a bunch of copy / paste or even find / replace.

  Thanks for any help!

  RoboHelp MVP of looonnngggg a long time ago...

  But what you might want to consider, is another variable to contain the desired text in the code snippet. This could be inserted inline. Then update you only in the variable.

  Just thinking out loud a bit.

  See you soon... Rick

• registration of user-defined presets error

  Presets contours registration error

  I uninstalled and reinstalled but the error is still there.

  Thanks a lot for your suggestions

  Giroux,

  I think that the good order/way is to update the operating system, and then reinstall the applications. Which was how you did it?

  It may be best to reinstall using the way complete three steps (the otherwise strange things may persist):

  (1) uninstall (check the box to delete the preferences),

  (2) run the cleanup tool, see the link below,

  (3) reinstall.

• user-defined types

  Hi all

  I have a function that returns a type defined by the user in my sql environment. The type consists of 5 different columns. I pass a ref_id to my function, on the basis of which he does some calculations and returns me the type.

  create or replace type my_type

  (

  number of col1,

  col2 varchar2 (100),

  COL3 varchar2 (10),

  number of COL4,

  number of col5

  )

  create or replace function fun (number in_id) return my_type

  as

  Start

  -code1

  -code2

  Return (my_type)

  end;

  In my sql environment, I have a table which is the following structure

  create table tab1

  (

  number of emeline

  upgvc varchar2 (100),

  number of Ref_ID, - this ref_id when it is passed to the function above will return a populated user-defined type values.

  number of col1,

  col2 varchar2 (100),

  COL3 varchar2 (10),

  number of COL4,

  number of col5

  )

  I have a table tab2, using which i will be filling of the columns of the table tab1, tab2 table structure is as below

  create table tab2

  (

  number of emeline

  upgvc varchar2 (100),

  number of Ref_ID)

  now I have to fill each column in table tab1, tab2 table and my pleasure to feature.

  something like

  Insert into tab1

  Select emeline,

  upgvc,

  Ref_ID,

  Rest of the values must be completed by calling the function using the ref_id and fill in the values. What would be the best way to do it? I have millions of records with it. I tried to use this with the function of REGAL and tried fill lines, but its slow.  All of the suggestions.

  Note: apologies for not sticking scripts and the original code since it will take days

  Thank you

  To implement this in the database, I use the following script:
  
  CREATE OR REPLACE TYPE IMPROG. SECONDMAX_J as object
  
  (
  INTEGER key,
  
  public static function ODCIAggregateInitialize (sctx IN OUT SECONDMAX_J)
  
  Return number
  IN THE JAVA LANGUAGE

  ,

  Number return value)
  IN THE JAVA LANGUAGE

  ,

  IN THE JAVA LANGUAGE
  NAME "Java.Math.BigDecimal return of SecondMax_j.ODCIAggregateTerminate (double [], int).
  ,
  
  
  
  Member ODCIAggregateMerge (self IN OUT SECONDMAX_J function,
  
  CTX2 IN SECONDMAX_J) return number
  IN THE JAVA LANGUAGE
  NAME "Java.Math.BigDecimal SecondMax_j.ODCIAggregateMerge return (oracle.sql.STRUCT)".
  );
  /
  
  CREATE OR REPLACE FUNCTION F_SECONDMAX_J (NUMBER value) RETURN NUMBER
  
  PARALLEL_ENABLE
  
  AGGREGATION to the HELP of SecondMax_j;
  /
  
  
  
  When I now use the F_SECONDMAX_J function.
  
  "(Columnname) select F_SECONDMAX_J from Tablename t;
  
  It works perfectly and shows me the right result.
  
  Then I tried to implement the fusion part as follows:
  
  public BigDecimal ODCIAggregateMerge (oracle.sql.STRUCT ctx2) throws SQLException {}
  
  BigDecimal Key2 = null;
  
  BigDecimal ctx_max = null;
  BigDecimal ctx_secmax = null;
  
  BigDecimal ctx2_max = null;
  BigDecimal ctx2_secmax = null;
  
  retrieve the context stored with the key
  StoredCtx_SecMax ctx = null;
  try {}
  CTX = (StoredCtx_SecMax) ContextManager.GetContext (Key.intValue ());
  } catch (Exception e) {}
  
  }
  
  Object [] impAttr = ctx2.getAttributes ();
  
  Key2 = (BigDecimal) impAttr [0];
  
  retrieve the second context stored using the key2
  StoredCtx_SecMax ctx_sec = null;
  try {}
  ctx_sec = (StoredCtx_SecMax) ContextManager.GetContext (key2.intValue ());
  } catch (Exception e) {}
  
  }
  
  ctx_max = ctx. LeseMax();
  ctx_secmax = ctx. LeseSecMax();
  
  ctx2_max = ctx_sec. LeseMax();
  ctx2_secmax = ctx_sec. LeseSecMax();
  
  If (ctx2_max.compareTo (ctx_max) == 1)
  {
  If (ctx2_secmax.compareTo (ctx_secmax) == 1)
  {
  CTX. SchreibeSecMax (ctx2_secmax);
  }
  on the other
  {
  CTX. SchreibeSecMax (ctx_max);
  }
  CTX. SchreibeMax (ctx2_max);
  }
  on the other
  {
  If (ctx2_max.compareTo (ctx_secmax) == 1)
  {
  CTX. SchreibeSecMax (ctx2_max);
  }
  }
  
  return a SUCCESS;
  }
  
  When I now try the function
  
  "Select / * + parallel (t 4) * / F_SECONDMAX_J (Columnname) of Tablename t;
  
  I always get a pointer NULL-error because the variable key2 is always 0 and therefore the functions LeseMax() and LeseSecMax()
  in the second context 'ctx_sec' produce this error NULL pointer.
  
  To me it seems that each parallel process is the construction of an additional class for himself, which is not available are my main process.
  
  My question is now how it is possible to access the context of stored of the parallel process, so that I can combine the results.
  
  Thank you very much

  Hi Josef,

  just guess that I've never implemented with java user-defined aggregate functions or support parallel execution:

  Maybe you have to implement ODCIAggregateWrapContext?

  + Application of ODCIAggregateWrapContext is optional. It should be implemented only when the external memory is used to hold the aggregative, context and the user-defined aggregate is evaluated in parallel (which is, stated as PARALLEL_ENABLE). If the user-defined aggregate is not evaluated in parallel, ODCIAggregateWrapContext is not necessary. +
  [http://docs.oracle.com/cd/B12037_01/appdev.101/b10800/dciaggfns.htm#i1004974]

  Report it to progress and success.

  Good luck
