Simply activate your expression.

not tested

SELECT to_date('30/03/2010 11:48:29','dd/mm/yyyy HH24:mi:ss')-TO_DATE('01011900','DDMMYYYY') FROM dual;

  • How to convert datetime in a JSF page or within the object entity of seconds since 1970

    Please HELP I have a column of type bigdecimal seconds since 1970 representing datetime.

    for example

    DateTimeCol

    1333382669.06

    expected output for the datetime type is 2012-04-02 16:04:29

    I build JSF form that display the column DateTimeCol. DateTimeCol type and Date format

    YYYY-MM-DD hh: mm: but the output of the column DateTimeCol is 9616-11-09 03:09:06 and it won't.

    I do not know how to convert (1333382669.06 seconds since 1970) in datetime (2012-04-02 16:04:29)

    I'd appreciate your help.

    Your problem is that the date data type coming milliseconds and not in seconds. You should be abel to do the math and use a

    java.util.Date(your_sec*1000).tostring ();

    Google for a timestamp converter (e.g. Epoch Converter - Unix Timestamp converter) and enter your number

    Entry 1333382669.06 * 10 = 1333382669060 lets you get: (here I use only * 10 that you already have 1/100th of a second!)

    Assuming that this timestamp is in milliseconds:

    GMT: Sunday, March 24, 1974 06:24:26 GMT

  • How to convert a large number to the spell without truncate to 32-bit.

    I'm trying to convert a hexadecimal number (string). The number is truncated to 32 bits, which is not what I want. For example, the number 28037546508295 (double) must be 0 x 198000000007. LabVIEW truncates and the resulting string is 0x7FFFFFFF, using number of Hex String.vi. I'm stuck. Thank you.

    'Number of hexadecimal string' accepts only data of I32. So, you should see a red dot of coercion when you connect your floating point number.

    You must use "Format of value" (also in the String > number of rope/coercion-pallet) and use '%x' as a format string.

    hope this helps,

  • How to convert DateTime xml in xdp (Designer)?

    You can do this way...

    Bind the date field in your XML tag.

    Set the model display to the date field.

    Place the following code in the initialize event of the date field.

    The value JavaScript as a language.

    var dtStr = this.rawValue;
    var pos1 = dtStr.indexOf ("-");
    var pos2 = dtStr.indexOf ("-", pos1 + 1);
    var strMonth = dtStr.substring (0, pos1);
    strDay = dtStr.substring var (+ 1 pos1, pos2);

    Assign the value to put in shape to the Date field.

    this.rawValue = strYear + '-' + strMonth + '-' + strDay.

    Hi wendellw,

    If you have received the redemption code, then you should go online at http://adobe.com/go/getserial to redeem your serial key

    However, if it's a 24-digit code, then that must be the serial key that you can use to update the licensed software.

  • How to convert Date floating number

    Hi everyone, I want to make a time measure of the hall sensor and use that value to set a frequency, and also to use as the value of process in a PID controller. the problem is that I get a result of dynamic data and I would like to have this in a floating number, is that possible? or another way is also good... hereby a jpeg to make it more clear.

    I also have more problems with that, when I change the throttle (0-100%) is does nothing and my time loop also doesn't stop more. This is just a small part of the full program, it's may be heavy for my computer? (core 1, 6 GHz, 1, 5gig of ram)

    hope it's a bit clearer what I mean

    Thanks in advance!

    PS: I know that the fracture by one is useless because you can directly measure the frequency, which has already changed.

    the program is intended to push a PMSM motor

    You can change the type of dynamic data for the meter using the function of Double-precision float in the digital - Conversion scheme.  For your other question, you are not showing your loop together so I can't help you there.  What stops the loop?

    Hi everoyne, I need to make a program simple calculation of the GPA in 5 classes. Where A, B, C, D, F are the entries for each other...

    Here's what I've done so far.

    But it seems that it is not recognized when I assigns numeric values to each letter. So I would appreciate any help. I tested for the release of "GP" and input A (4) = CT. The answer for GP should be 4 x 3 = 12. But I get a number beyond that.

    I'm relatively new to Labview so sorry if this is a stupid question.

    I would like to make a table of the clusters.  Each element of the array corresponds to a single course.  Inside of the bunch, I would have a string for the name of the course, an enum for the grade and a digital for the number of credit hours.  Use an enum for the grade, so you can make sure that the user space only in the values that you no longer the enum is actually a number.  No actual conversion.  Then you just use a loop FOR (autoindexing) including some shift registers to keep your totals, then divide the totals of the year by the credit hours.

    Acrobat Pro has 'actions', but they are designed for the automation of the light trucks. I recommend you do not more than 200 at a time, leaving Acrobat between each of them.

    However, I must comment on the premise. Conversion to Excel is a very uncertain task, based on conjecture and rarely is exactly what is needed. Individual inspection of each file Excel with adjustment, rejection or leisure is usually considered a must.

    If you have a large number of identically to the PDF format, you must look or an application that is designed to extract based on this provision, rather than leaving to the conjecture of the commission.
