• component module (function) in the Toolbox of data base

  Hi, I have been using the Toolbox of data a lot, but I've never used a function of my Access database before.

  I have a function called "Work_Days" that takes two dates as Inparameters and calculate how many working days it is. This function is stored in the Modules section in Access.

  I have a working query I can run with access which looks like this:

  SELECT tblActiveCCU.ID, tblActiveCCU.DateReceived, tblActiveCCU.DateTransferred, Work_Days([DateReceived],[DateTransferred]) AS NetDays
  FROM tblActiveCCU
  WHERE (((tblActiveCCU.ID)=97));
  

  The output looks like this:

  ID   DateReceived    DateTransferred NetDays
  97  3/16/2016   3/30/2016   11
  

  Now to the question, how I implemented this request in LabView?

  In my attached code, I got a "syntax error" FROM clause

• Script to determine the days between dates

  I'm totally new to JavaScript.  I try to do a calculation with a custom calculation script field.  I tried to restore something with script I have checked in several forums, but not completely succeeded.  I have 4 form fields.  2 date fields, a body of numbers (formatted for currency) and the field of computing.  The calculation I'm trying is ((365-(jours entre les 2 champs de date)) divided by 365) times (currency field).  Any help would be greatly appreciated.

  Event.value = () ((365-(xdays)) / 365) * (this.getField("premium1").value) ) .toFixed (3)

• Can I perform calculations on the values of date?

  I'm trying to set a range of dates using two calendar features by entering a date "from" and a "to".

  This is done using a JavaScript that is bound to a textbox control for entering a date.  He is my date "from", if I can check this date against today to confirm that the date is later than today, that is in the future.  I have no experience with javascript, but know PASCAL.

  I then a second box with another calendar date, I want to automatically fill this box on the same date as the first area unless physically, the user wants to change the date of the last.

  Can anyone help?  I'd appreciate some tips so that I can try and learn a few Java along the way.

  GetField ("Text1") .value = s;

  There are two problems with that. The method is getField, not getfield. You must also pass the name of the field as a string. So it should be:

  s = getField("text1").value;

• Possible bug in DateTime in the Toolbox of data base

  Hello!

  I do not have the database Toolbox, and it seems that you can not download a 64-bit evaluation...

  Bug?  I wrote to the DateTime fields to a database through the appropriate use of clusters and Inserts, but it seems that I never get from fractions of a second. Datetime controls show and the fields of database should help (at least it's montrer.000 at the end) so I wonder: does somehow use locale at the moment so this is my comma decimal point and landing so fractions?

• Is there a difference in the opening between the lenses?

  Happy holidays.

  I thought too new.  I'll start with what is probably a false assumption.  Suppose I have a lens that uses a 58mm filter and another that uses a 77mm filter.  For the sake of the argument, I suppose that elements of lenses in order to filter 58mm are 58mm and 77mm lenses in the goal of 77mm filter elements.

  For the reasoning, suppose that both lenses have a focal length of 50mm.  The point being, all things are equal except for the diameter of the lenses in both lenses.  Assume that both lenses are both sides with an aperture of f/1.8.

  My question is this.  The larger lens let more light than the smaller goal when both lenses are set to the same aperture setting?

  The short answer is, no.  F1.8 or f2 or some f-stop, that's exactly right.  No matter what the lens is the size.  Since it is a ratio, the actual size of the aperture blades will be different but f1.8 will always be f1.8.  He will leave in exactly the same amount of light.

  Not even two 50mm lenses with items of different sizes will be identical, but the ratio f-stop will be.  Exactly the same amount of light going through it.

  If it was not so count in a camera would be impossible.  I hope this is clear for you.

  I have a query DBA_DATA_FILES show total space allocated.

  SELECT SUM (bytes) AS allocated_bytes FROM dba_data_files;

  And for 'used' space, I run the present:

  SELECT SUM (bytes) AS used_bytes FROM dba_segments;

  We don't need to digress into the discussion of what is truly used as everyone knows that there is unused space in DBA_SEGMENTS. But it works for management!

  I have a report automated that send me monthly. The same report even it breaks down by tablespace... allocated and used as I noted above. Then, I put it in Excel to generate the graph.

• Foreign key constraint, not recognized during the synchronization of data with the model dictionary

  Hello

  Data Modeler is a foreign key constraints do not recognize when synchronizing data with the model dictionary, although the foreign key is there (in the database that a data dictionary is read). I can't find any criterion when a foreign key is not recognized by the Data Modeler. Are there limits to the length of the attribute, or the number of columns in a foreign key, or other limitations which may lead to this behavior not to recognize a fk by Data Modeler? I have columns more than 32 characters. I compared with the fk is recognized by DM, but I can't find anything that indicates why it is not recognized.

  I wonder if someone also has constraints of foreign keys that are not recognized in the comparison of data bases and model?

  Thank you

  Then, you use the wrong cursor and you performance degradation because the cursor returns data that is not required.

  We can extract a particular of ref cursor column, please suggest me

  You can not.

  Workaround would be to copy the handle of the cursor ref to a handle to the cursor DBMS_SQL and then use cursor DBMS_SQL to treat the projection of SQL. But it would be an ugly hack.

  The right approach would be to correctly use the SQL cursors in PL/SQL. And no, ref Cursor in PL/SQL (created by code PL/SQL to PL/SQL code) is almost always the WRONG choice.

  There are better native cursor data types in PL/SQL in particular supported cursors created by PL/SQL and PL/SQL.

  REF CURSOR is provided mainly as the cursors created by PL/SQL for an external client. There are very few reasons to create Ref cursors to use PL/SQL code.

• Difference between the true Date of the Hijra with date Hijri Oracle

  Hi all
  
  I'd appreciate if someone please let me the solution for this problem. In my application, I displays the Hijri Date using the NLS parameter. but the question that "I'm dealing with a deference between the date of the real Hijra with the date of the Hijra oracle."
  
  
  Assume that the actual Hijri date 18-SEP-2012 was 02/11/1433 in hijri but in oracle was 03/11/1433
  
  When I run the following query it shows me "1433/11/03", but the actual date of the Hijra is "" 1433/11/02.
  
  Select to_char (to_date ('20120918', 'YYYYMMDD'), ' DD/MM/YYYY', ' NLS_calendar = "' |') Hegira ARABIC ') FROM DUAL;
  
  
  IFTIKHAR

  Check

  FAQ on the calendar of the Hijra (Hijri) [ID 121061.1] Arabic
  and
  Conversion algorithm to Date in the Gregorian calendar until then Arab (Hijra) [ID 130551.1]

  Support of Oracle.

  If you have a file called lxecal.nlt file

  for Oracle 8 to $9i ORACLE_HOME/ocommon/sln
  for Oracle 10 g and more $ORACLE_HOME/nls

  so maybe that's the difference you see originally.

• Groovy Script to find the difference between Dates

  I am trying to build a script that takes a date from a RequestField and calculates the number of days between this date and the current date (from session).

  So far, I have a problem, the analysis to-date from the RequestField chain. I found this code but it doesn't seem to work...

  date = new Date().parse('yyyy/MM/dd', '1973/07/09')
  

  I get the following error...

  Error Message: groovy.lang.MissingMethodException: No signature of method: java.util.Date.parse() is applicable for argument types: (java.lang.String, java.lang.String) values: {"yyyy/MM/dd", "1973/07/09"}
  

  Any help would be greatly appreciated.

  Hello

  What version of server? The extract you have here works fine on mine (563).

  This also works for me

  new java.text.SimpleDateFormat('yyyy/MM/dd').parse('1973/07/09')
  

  See you soon

• How to find the time between two channels of entry in the data acquisition card or pci 6036

  Hello

  I read a lot-related posts on the simultaneous measurement of two input voltage of similar channels in map data acquisition. I know that the best material is "simultaneous measurments of the Series DAQ cards" but I only pci data acquisition card 6036 and I try to understand what is the time between the reading of the two channels . This period is always constant? (must it rely on a voltage (amplitude, frequency, waveform..). I send the sine wave (s) to the two channels and read the values of V, if they read the same value, the difference should always be zero but I get-0,002 to 0.002 Volt difference (I must find a way to convert it in time). A screenshot of my VI is attached. I wonder how I can accurately measure the time delay between the channel.

  I am open to any suggestion, my final goal to read exactly two channels at the same time ((ou connaître le délai exact donc je peux correspondre les données correspondantes étant donné le temps de retard))

• Huge performance difference between stored proc and anonymous PL/SQL block.  Why?

  Hello!  I searched various online resources and have been unable to find those who have addressed this problem, so I hope that someone here may be able to offer advice.

  I have a stored procedure that is approximately 300 lines long, takes no parameters, and sets a record and a few types of internal tables.  When I run it on a particular data set, it takes about 50 seconds at the end of my environment.  Unfortunately, it will have to be performed as a block anonymous PL/SQL instead of a stored procedure, because of the policies that exist about the environment which I deployment.  However, when I converted it to an anonymous PL/SQL block, make no other code changes whatsoever and it connecting the same schema that belongs to the stored procedure, it takes about 6.5 minutes (nearly 8 times as long) to complete.  Aside from the burden of analysis and validation, which could add a fraction of a second, can someone please suggest some possible reasons for the large performance difference and offer advice on what I can do about it?  In which case it is important, the procedure uses in bulk binds (for example, in bulk collect, forall) where it makes sense and doesn't call other objects in PL/SQL.  Thanks in advance.

  Without seeing your code, it is difficult for me to contribute more.

  Note also that...

  1 roles are turned on in the anonymous blocks but not (at least not by default) in the stored procedures. This is why the anonymous block could have MORE rights (those granted through roles) probability that you can get more items through anonymous block.

  2. ensure that, in both cases, it does reference the same target tables.

  Debug by calculating the difference of time after certain steps in your code. Who should get an idea on this or activate the trace.
