• 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

• How to print dynamically added columns in Flex

  Hello

  I use a component AdvancedDataGrid in Flex 3.6 application. My ADG displays a variable number of columns, so some columns are hardcoded (declared in MXML) and some are added dynamically (ActionScript). It works well. But when I try to print my ADG, only hard-coded columns are printed.

  Any idea?

  I found the problem.

  I used groupedColumns for hard-coded columns statement and I used new AdvanceDatagridColumn("columns") for the added dynamically. Fixed it using columns for both.

  Hope I could help somedy.

• How to map the csv (not columns) cells in the columns of table, import with sql loader

  Given «example.csv» csv file

  Oracle table "exampletable" and so on. The csv file has not ordered rows and columns, so I can't just load the csv file into a new table itself. So what I'm asking is how to map to the columns in table cells load this file into Oracle (XE). Can someone point me to a tutorial?

  I know it's quite elementary, please let me know if I am sous-prescrit anything in the question.

  I ended up doing in Excel, through a very laborious process that will probably be repeated by others.

  What a pity that there is no functionality in Oracle for this kind of data import more flexible. Analysts of data often throw himself spreadsheets that look like this (or 485 of them) who must enter data one way or another.

  

• How to call a query of the support bean?

  Hi all
  
  Another question for you guys:
  
  I did a page jspx with an entry form and a "submit" button.
  When I click the button submit, the action in my grain of support my_action is executed.
  This is the code:
  
  
  public BindingContainer {} getBindings()
  Return BindingContext.getCurrent () .getCurrentBindingsEntry ();
  }
  
  public String my_action() {}
  BindingContainer links = getBindings();
  OperationBinding operationBinding = bindings.getOperationBinding("EmployeesView");
  Object result = operationBinding.execute ();
  If (! operationBinding.getErrors () .isEmpty ()) {}
  Returns a null value.
  }
  }
  
  I was hoping that the "EmployeesView" query has been run in this way, but I get the following exception:
  
  java.lang.ClassCastException: oracle.adfinternal.view.faces.model.binding.FacesCtrlHierBinding cannot be cast to oracle.binding.OperationBinding
  
  
  So how should I run query EmployeesView?

  In this case use example 9-13, access to the Interface of Client Application Module in a JSF Backing Bean using a link of Action named:
  http://download.Oracle.com/docs/CD/E15523_01/Web.1111/b31974/bcservices.htm#sthref918

  So rather than get an operation binding - get you the pointer to the AM across the link - line 4.
  Then on the AM you can call the service method, or instead, use the findViewObject method to locate your specific VO, change and then run the query on the matter. Then, wrap everything in the VO.hasNext () and use the following method on your VO for the data lines.
  And then you are iterating over the lines of the VO and add them to any list/collection you pass to the BPEL.

  This video could help in terms of interaction with a VO and get the lines:

• Tabular: how dynamically toggle columns and rows

  Hello
  
  I am very new to ApEx sorry if this has been addressed before, but I can't find a solution in forums or with Google, so here I am.
  
  I have an table based on a view, with two elements as the primary key and instead - of trigger for update (only the updates made, not of insertions/deletions) and the form works fine (I can update and refresh, etc.) The form was created with the wizard, not manually.
  
  My problem is, I need to turn off (disable - not hide) of columns in the report to prevent changes according to the value of one of its own columns - for example, a value of + 'q' + in the column period is going to turn some columns, while value of + 'h' + will toggle other columns. (The 'q' / 'h' value is the same for all the lines in the form.)
  
  Similarly, I also need to toggle all lines according to the value of the column one another .
  
  To sum up, displaying the form of tables and according to the value of a column, I need to turn some of the columns. Thenfor each line that I sail and, according to the value of another of the column, I need to enable/disable one or more items on this line.
  
  Any detailed help on how to proceed would be greatly appreciated (and if you need more information please ask.)
  
  It was very easily in forms with the triggers when-new-record and the elements of parameters as enabled. I am really so confused as to how to do this with ApEx - not to mention that I am helpless with JavaScript... Given that the page works well with the wizard-generated form, I want to keep it this way, but I'm ready to learn new tricks if the solution is building manually (as explained here: http://www.oracle.com/technology/products/database/application_express/howtos/tabular_form.html) or do it with a dynamic query (as explained here: http://www.oracle.com/technology/products/database/application_express/howtos/dynamic_report.html) although I'm not sure to understand things , explained here (and if she needs clean MRU treat...?)

  The old packed timesheet application has the tip for how to display the day of the week selected by the user in the form of columns in the tabular presentation.

  Reference: old packages of timesheet Application

  That's how I'd do:

  • Select the range of dates populate the days between the date columns range in a collection of the APEX.
  • Display the columns as editable using the APEX_ITEM API.

  NOTE: Application of time sheets there was select list for weeks, so always the number of dynamic columns would be 7 + column code time.

  Also, the maximum number of modifiable columns, you can use on your page APEX is 50.

  Thanks for your reply and I completely understand your frustration. The problem is sometimes it is very difficult to describe all of the problem due to several reasons. Please take a look at my last post to see if that makes sense.

  If you really need SQL dynamic - true dynamic SQL which includes dealing with dynamic number of bind variables - then DBMS_SQL are an excellent interface to use.

  You can generate the dynamic SQL statement based on the question of whether the filter criteria is null (do not use) or not null (use as a predicate). For example

  if someParam10 is not null then
    // someParam10 needs to be used as a filter predicate
    dynamicSQL := dynamicSQL || ' and some_col_10 = :someParam10 ';
  end if;
  

  This statement can then be analyzed using the DBMS_SQL interface. The binding of values uses the same logic that was used to create predicates. For example

  if someParam10 is not null then
    // someParam10 is used and needs to be bound
    DBMS_SQL.Bind( myCursor, 'someParam10', someParam10 );
  end if;
  

  So, with this approach simplistic, you can easily create a dynamic SQL with variable predicates, dynamically bind these and run the slider.

  Bind variables are used in the dynamic SQL statements, as there are very few threats of SQL injection. And the basic principles observed for shareable SQL creation - the same set of parameters not null to filter, will result in the same SQL statement, which allows the cursor within the Pool shared for this SQL statement to be reused.

  So, technically, dynamic SQL is not a major problem (if used correctly). The major problem is that if really necessary to address the requirements of the business at hand.

  The problem I have with many comments here want to use dynamic SQL statements, is that it is used as one would use a file i/o interface.

  For file IO you want standard Open(), Read(), Write() and Close() calls. And you, the appellant, simply pass the name of the file and the data to write or to receive the data read.

  Similarly, these posters want to use SQL to open a table and read and write the data column - and do it by calling simply (and dynamically) by specifying the name of the table and column. Approaches to dynamic SQL based on one such concept is wrong. And shows that much of the ignorance of what a RDBMS is and how to use an RDBMS.

• How to make dynamic form fields updated?

  This is going to be an ugly post, just be careful! :)
  
  I have a form that retrieves his labels and text input field names dynamically from a database. Rather than having the form hardcoded, we are able to add new columns to a table and the form automatically adds the new labels and fields via CFQUERY.
  
  When the form is completed and submitted (post method), the database is supposed to be updated. However, because our names of input fields are populated through query, we can not write a query to update static when we add new elements of form.
  
  So, I have a solution to this (in my head), but I'm stuck in a bit of logic and can't get it in the code. I'm looking for a way to write FORM #. # fieldname # (here is where it gets ugly). Because the form sent by the post method, I find myself with a bunch of FORM.fieldname on my action page (and fieldname is generic for what are real variables).
  
  So here's how I am update:
  I have a table (let's call it table1) that contains a column of all the column names in the data table (table2). This table is used for query purposes only, no data is updated here of the form.
  I have a table1 request to call all the column names in table2.
  < cquery datasource = "exdb" name = "exname" >
  SELECT ColumnName
  FROM table1
  < / cfquery >
  Then I write the update query that will update the elements they are loop using CFOUTPUT:
  < CFOUTPUT QUERY = "exname" >
  < cfquery datasource = "exdb" name = "exupdate" >
  UPDATE table2
  SET #columnName # = #FORM. < columnName > #.
  WHERE itemID = #FORM.itemID #.
  
  It's my dilemma. As you can see, the cfoutput is a loop... So we will take the first element in the loop, call him 'name1 '. So our query update said SET name1 = #FORM.name1 #, and it will update the table with what was presented in the entry for name1 field. The cfoutput to loop again, this time it's of name2. SET name2 = #FORM.name2 #. Now, the form includes a hidden itemID to specify where the table should be updated, as you can see above. So, now that you see how it works, my problem is to get #FORM. < columnName > # FORM.name1, FORM.name2, etc.
  In Coldfusion, you would write #FORM.variable # to call a FORM element. However, given that the variable is not defined, and allows us to fill a request, we make SHAPE #. #variable # where #variable # must be resolved before #FORM. ___ #
  
  You are with me on this? This is very complex in the explanation, but if you need more information, I can provide more clearly. I would like to know what you think. Really, I have the solution, but to FORM #. # columnName # to solve is another problem. I think what I need is to understand the order of operations for this statement, so #columnName # resolves first.

  You'll want to use the scope structure notation when dealing with your form variables. The Form.SomeVar variable can also be written as ['SomeVar']. Using this syntax, you can do something like this:

  UPDATE table2
  SET #columnName # = #FORM [columnName] #.
  WHERE itemID = #FORM.itemID #.

  You can also look on the following to help optimize your code:
  (1) learn how to use - it could speed up your code a bit.
  (2) according to the DB that you use, you may be able to combine all of your UPDATE within 1 SQL commands block. This will allow to do all your actions with 1 DB connection database, instead of a bunch (works in MSSQL, Oracle or MySQL, not sure)

  Hello

  as suggested, you can use jQuery selector.

  In your report the static id value we will say MYTABLE, and then in the same region in the page footer section established

  The 'tricky' part by their Summit, it is that when you set static id really put you it to the region (which is defined as a table) and not for the table that is in fact the data display. This table is part of the table for which you configure static id. That's why you use the selector "chart".

  Kind regards

• Sort on dynamic query problem!

  Hello
  
  I have a dynamic query written in pl/sql, when I check "Sort" for each field in the report attribute, error message resurrected as "ORA-01785: ORDER BY item must include the number of an expression in the SELECT list.
  If I do not check sort, it works very well. In my applications, I need all the fields sorted by user, how do I solve this problem?
  
  My query as below:
  
  declare
  Ask varchar2 (2000): = "select";
  s_class varchar2 (1000);
  cursor c1 is select * from demo_preference;
  Start
  for c1_val looping c1
  If c1_val.login is not null then
  query: query = | » ' || 'login ' | ',';
  end if;
  If c1_val.id is not null then
  query: query = | » ' || 'id ' | ',';
  end if;
  .......
  end loop;
  query: = SUBSTR (query, 1, length (query)-1);
  
  s_class: = ' (NVL (: P2_class, "%" |)) ''null%'') = ''%'' || "zero percent" OR
  EXISTS (SELECT 1 FROM apex_collections WHERE collection_name = "P2CLASSCOL" AND class = c001))';
  
  query: query = | » ' || ' from ming.reg_report_view1 where '.
  || ' ' || s_class;
  Return (Query);
  end;

  Maybe the internal column used when you clicked the sort is not indicated in the report. Try to use aliases when you build the query string, it might help apex internally to identify a column even if its order is changed to another user. After all, the order of the columns in the code is dynamic and I assume that even the number of displayed columns can vary that could sort on a column that is identified by a number not valid.

  How about somewhere, displaying the report query so that you know what is the exact query processing, it could give you the best information on the problem.

  If the problem persists, use a collection that is extracted these record using the same query string, then replace the report to view the collection and then set the sort column on. This way Summit could get confused about which columns are being sorted and it would just sort on a c001... C050 column as if it were a string (Yes problems with the number of sort columns when you do this).
