• Retrieves the name of the variable

  Hello

  I'm trying to change the OpenG changed? Subvi (see below) so that he will write the new value of the variable sent to 'Variant' if changed on the disk (using the following config VI). To do this, I need to somehow extract the variable name of the variable (any type) which was connected to the entrance of variant of the changed? Sub - VI by VI calling so that I can use it as a key name. Is this possible? This information is still transmitted to the Subvi?

  

  If you use openg, there is a "Get the name of data" function that retrieves the name of the data passed in the Variant.

  SQL language reference

  Nonquoted identifiers are not case sensitive. Oracle interprets them as letters.

  Quoted identifiers are case sensitive.

  By enclosing the names in quotes, you can give the following names to different objects in the same namespace:

  'employees '.

  'Employees '.

  'EMPLOYEES '.

  Note that Oracle interprets the following names the same, so they cannot be used for different objects in the same namespace:

• the variable name of database query to SQL Server using the Oracle database link

  Hi all
  
  I have an ApEx 4.1 application running on x 64 (11.2.0.1) 11g on Windows Server 2008 x 64, and I have a few points of data integration with SQL (2005 and 2008) server that I need to create. I have configured the database with dg4odbc link and it works perfectly... I can run queries on the SQL Server database without any problem using the database link.
  
  However, there is a scenario where the SQL Server database name is dynamic, and I need to generate on the fly in a PL/SQL block and then use it in a query dynamic SQL (all this in the ApEx). It of wherever I meet problems... when I asked the default database that is based on the ODBC connection and I don't have to specify the name of the database, no problem. But when I need access to one of the several other databases by default, I received the error "invalid table.
  
  It works well:* (note that 'fv' is the name of my database link)
  
  v_query1: = "select 'Release Date' from dbo." Schedules@FV where dbo. Annexes. "" SchedID "=: calendar";
  EXECUTE IMMEDIATE v_query1 in rel_date using the grid.
  
  
  
  
  I then take this rel_date variable, convert a varchar2 (rel_date_char), then use it as the name of the database in the following query...
  
  
  _ It returns an error(error ORA-00903: invalid table name)
  
  v_query2: = "select"PARTNO": rel_date_char.dbo.ProdDetails@fv where 'SchedID' =: calendar and"UnitID"=: unit"

  EXECUTE IMMEDIATE v_query2 in part_number using planning, master, parent unit;
  
  
  
  I also tried using all of the following conditions without result:
  
  "select"PARTNO"of" | : rel_date_char | '.dbo. ProdDetails@fv where 'SchedID '...

• Store the variable names in a database

  Salvation;

  I am storing calculations in a table of data and the need to recover them and run them in a query, one of them needs to access the value of an argument passed to the function to run the query/calculation. Problem is that I'm not sure how evaluate the variable when it is retrieved - it is not treating.

  Any ideas?

  Here's the function:

  <cffunction
   name="fnShowliveSurcharge" access="public" output="true" 
  returntype="any" hint="makes a calculation based on a formulae" >
  
          <cfargument name="avgCost" required="true" />
  
      
  
          <cfquery name="qryGetAlloys" datasource="#variables.dsn#" result="qryGetAlloys_results" >
  
              select * from nas_alloys;
  
          </cfquery>
  
          
  
          <cfquery name="qryGetGrades" datasource="#variables.dsn#" result="qryGetGrades_results" >
  
              select * from nas_grades order by id;
  
          </cfquery>
  
          
  
          <cfloop query="qryGetGrades">
  
              <cfloop query="qryGetAlloys">
  
                  <cfquery name="qryGetSurcharge" datasource="#variables.dsn#" result="qryGetSurcharge_results">    
  
                      select 
  
                          #qryGetAlloys.formulae# as myValue
  
                      from nas_alloys a left join nas_triggers t on t.alloyid = a.id
  
                      left join nas_astm astm on astm.alloyid = a.id
  
                      left join nas_estimatedprice ep on ep.alloyid = a.id
  
                      where astm.gradeid = '#qryGetGrades.Id#'
  
                      and a.id = '#qryGetAlloys.Id#';
  
                  </cfquery>
  
              </cfloop>
  
          </cfloop>
  
          
  
      </cffunction>
  

  the second line of the query is the insertion

  ((#arguments.avgCost#-t.value) * (astm.astm/100) * 1.2)

  the nas_alloys table, however the query ends up looking like;

  Select ((#arguments.avgCost#-t.value) * (astm.astm/100) * 1.2) as myValue nas_alloys a left join nas_triggers t on t.alloyid = a.id left join nas_astm on astm.alloyid astm = a.id left join nas_estimatedprice ep on ep.alloyid = a.id where astm.gradeid = '1' and a.id = '1';

  Instead of:

  Select ((2.2289-t.value) * (astm.astm/100) * 1.2) as myValue nas_alloys a left join nas_triggers t on t.alloyid = a.id left join nas_astm on astm.alloyid astm = a.id left join nas_estimatedprice ep on ep.alloyid = a.id where astm.gradeid = '1' and a.id = '1';

  Any thoughts on how to solve this problem?

  Conditional logic is possible in sql in various ways.  One way that works with anything is a case construction.

  Select case when something, then this

  When something else while

  else no matter what

  end fieldname.

  Then there are features like ifnull, coalesce, decode, etc..  Here are the specific db.  I do not use MySql so I can't tell you what functions there.

• Get the name of the variable

  Hello

  May be a simple question, but I can't understand how in fact.

  When I do this

  //--------------------

  var obj:Object = new Object();
  obj.test = 'My Test';

  for (var i: * in obj)
  trace (I + ":" + obj [i]);

  //--------------------

  The output is-> test: test my

  My problem is when I put an object inside the object

  //--------------------

  var obj:Object = new Object();
  obj.test = new Object()

  obj.test.secondTest = 'My Test';

  for (var i: * in obj)
  trace (I + ":" + obj [i]);

  //--------------------

  The output is-> test: [object Object]

  So no idea how to get the name of the variable instead of [object Object], like the first release, but with the second code. I have an object inside an object.

  Thank you
  

  The following approach will dig its way.  I've added other variables to the main object just for the sake of the demo...

  var obj:Object = new Object();
  obj.Test1 = "test string";

  obj.test = new Object();
  obj.test.secondTest = 'My Test';

  obj.test2 = new Object();
  obj.test2.secondTest2 = new Object();
  obj.test2.secondTest2.val = "test deeper."

  function traceObjectVars(obj_arg:Object):void {}
  for {(var i: * dans obj_arg)}
  If (typeof (obj_arg [i]) is' objects ' ') {}
  traceObjectVars (obj_arg [i]);
  } else {}
  trace (I + ":" + obj_arg [i]);
  }
  }
  }

  traceObjectVars (obj);

• Getting the name of the variable?

  Hi, is it possible to get the name of the defined variable?

  You can retrieve the xmllist of the variables (string or otherwise), of any object (for example, the current timeline) using the following function.  each item in the list has a property of type with the name property:

  function variableF(o:Object):XMLList {}

  .variable describeType (o) return;

  }

• Bind the Variable Table name in the query of VO

  I have a VO that must have its clause defined dynamically at run time.  I have a string bind variable defined with a default value that is referenced in the query of the VO.  However, JDeveloper allow me to leave the definition of the query of the view object when the from clause is a variable binding, even if the binding variable has the default value.

  For example.

  Select

  « X »

  Of

  : TABLE

  where

  1 = 1

  The variable binding TABLE is defined as a string with a default value of the 'double '.  Did I miss something in the definition of the VO?

  Variables that start with an act of colon as global variables; they can be defined in a broader scope. The colon helps the compiler identify as being not necessarily defined in the unit being compiled.

  Why would you think that FORM_TRIGGER_FAILURE is triggered instead of ZERO_DIVIDE?

  In fact, I expect PLS-00103 encountered the symbol "DIVIDE" when waiting for the following..., because you have a space (DIVIDE ZERO) instead of a line of underscores (ZERO_DIVIDE). Cut and paste real code when posting here.
  If you fix that, then ZERO_DIVIDE is thrown in the procedure. An EXCEPTION handler keeps some errors that occur at the time reported to the caller. In this case, the EXCEPTION handler is not said "the ZERO_DIVIDE report as an error. Instead, cela... ». In this example, part of what he does on the contrary raises a different error, and it is the only error appearing on the appellant.

  Furthermore, "while some OTHER THEN NULL" is almost always a very bad thing to say.

  One thing that is oracle is often of short error messages, wave print-screen, but write long posts, detailed in trace files on the database server. Programmers are educated to search a trace file when they see some error messages. You could do something similar. Instead of (or in addition to) burn of trace files, you can insert rows in a table of logging of errors.

• retrieve the value column access via the variable name of the column

  I need to build a function of validation with this condition:

  The data model is like this:

  We have an array of items_general, with its id and data.

  Then we have specific tables, let's say... item_especific1, item_especific2 item_especificn. They have the same as the table of the item_general pk and fk against item_general

  Each element is in one of the tables item_specific and items_general.

  
  

  Now, the validation feature: I need to check for an element, if some special columns of the item_especificx table are null and will raise an error if this occurs.

  I got the name of especific_table and the list of names of particular column stored in another table.

  
  

  I guess I can browse this list of column table to build a clause concatening Dynamics 'and' | column_name | 'is nothing', but I'm not a big fan of the dynamic sql.

  
  

  Can you think of a better solution? Any way to access the value of the column by using the column name, as if it were a varchar2 key index?
  

  
  

  
  

  
  

  Nope, no filter.

  When you have a funky data like that model, you're destined to dynamic sql and other assortment of headaches.
