• ORA-1866 when you try to change the precision of the timestamp column

  Hello
  
  I use Oracle XE. I have a table that contains a Timestamp column. "Fractional precision" is 6 and "Time zone" has the value of HOURS LOCAL time ZONE.
  If I try to change the precision of the timestamp column (set to 2 for example), I get the following error:
  
  Error ORA-1866: the dattime class is not valid.
  The following SQL statement failed:
  ALTER TABLE CLIENTS
  CHANGE ("TIME_STAMP" TIMESTAMP (2) WITH THE LOCAL TIME ZONE)
  
  Please notify.
  Thank you
  MR. R.

  The column is empty? It should be just by reducing the precision.
  Try to run the command in the SQL Plus tool if you have not already done.

  The following should do the job

  ALTER TABLE CLIENTS ADD TEMPCOL TIMESTAMP (2);
  UPDATE CUSTOMER SET TEMPCOL = "TIME_STAMP";
  ALTER TABLE CLIENTS REMOVE THE COLUMN "TIME_STAMP";
  ALTER TABLE CLIENTS RENAME COLUMN TEMPCOL TO "TIME_STAMP";

• by comparing the timestamp

  Hi I need to compare in timestamp with microseconds in other words precition:
  
  Select * from any_table where
  TO_TIMESTAMP (DT_INSERIMENTO, ' dd/mm/yyyy HH24:MI:SS, FF6') = to_timestamp (October 27, 2011 16:18:36, 346560 ', ' dd/mm/aaaa HH24:MI:SSxFF9')
  
  
  and the game has just the line that fulfills the condition,
  so I don't want in the line with in the dt_inserimento column result set a different value
  2011-10-27 16:18:36, 346560
  for example line with
  2011-10-27 16:18:36, 444450
  
  How can I accomplish this?
  
  Thank you
  Francesco

  If this is the case, what about something like that?

  SELECT *
  FROM   any_table
  WHERE  dt_inserimento = TO_TIMESTAMP('27/10/2011 16:18:36.346560','dd/mm/yyyy HH24:MI:SSxFF9')
  

  If dt_inserimento is already a TIMESTAMP, you need not use the TO_TIMESTAMP function.

• reading the timestamp column in the txt file

  Hi pros labview

  I work with labview 8.6 for about 1 week and I need help in reading txt files.

  the textfiles that I read have 2-11 columns.

  the first column shows the time and others show different channels where I measured the voltages.

  It is therefore no problem with reading of the voltage-columns and put it on the y - axis to a chart of the vi but I can't the time on the x-axis column.

  I took the basic "read file.vi" and it has changed a little according to my needs.

  hope you can help me, getting time on the x-axis column. (perhaps with a xy chart?)

  the vi and I have to read txt file are attached...

  Here is an example. The formatting of the x axis relative time will now do something.

• Transpose the timestamp, columns of values in row

  Hello
  
  I have a table with the values of newspaper of some measures. This table Gets an entry each day, with the date time and only one value for each hour. The table model is something like that,
  
  Name_EST | Date | VALH1 | VALH2 | .... | VALH24
  Test | 09/01/2011 00:00:00 | 10.8. 5.4 | .... | 14.2
  
  Where the VALH24 VALH1 represents the value of a measure for each hour (09/01/2011 01:00 to 02/09/2011 00:00:00).
  
  I would like to know if it is possible to transpose this table so that I can have a diferent entry (row) for each hour, like this:
  
  Name_EST (Sami). Date | value
  Test | 09/01/2011 01:00 | 10.8
  Test | 09/01/2011 02:00 | 5.4
  Test | 09/02/2011 00:00:00 | 14.2
  
  I think it's simple to do using a stored procedure, but I would have preferred to make no. using a.

• By comparing the two columns in a datagrid.

  I have a datagrid that has a data provider for some users. Users have a name, address, balance and amount of the payment. For the amount of the payment, I use a custom MXDataItemRenderer like my TextEditor (no text rendering). I want to do is validate that the amount that they are entered in the payment amount does not exceed the balance.

  I tried to do it on an itemEditEndHandler, but the problem is that for some reason that I don't have the amount of payment at this time here. I wonder what I am doing wrong or if I go about it completely the wrong way.

  Any help would be greatly appreciated.

  Thank you

  Here's my editHandler function

  var point: Object = ((event.currentTarget as DataGrid) .dataProvider as ArrayCollection) [event.rowIndex];
  var paymentValidator:PaymentAmountValidator = new PaymentAmountValidator (item.balance);
  paymentValidator.source = this.dataProvider;
  paymentValidator.property = "paymentAmount;
  paymentValidator.validate (item.paymentAmount);

  Here is my custom validator.

  SerializableAttribute public class PaymentAmountValidator extends Validator
  {
  private var: table of results;
  private var scale: Number;
  public void PaymentAmountValidator (balance: Number = 0) {}
  Super();
  This.balance = balance;
  }
  
  Set the doValidation() method.
  override protected function doValidation(value:Object):Array {}
  
  Convert the value to a number.
  var inputValue:Number = Number (value);
  
  Table of clear results.
  results = [];
  
  Call the base doValidation() class.
  results = super.doValidation (value);
  Back if there are errors.
  If (results.length > 0)
  return results;
  
  If the input value is not a number, or contains no value,
  issue a validation error.
  If (isNaN (inputValue) |! value)
  {
  Results.push (new ValidationResult (true, null, 'NaN',
  "You must enter an amount."));
  return results;
  }
  
  If (inputValue > balance) {}
  Results.push (new ValidationResult (true, null, "moreThanBalance",
  "The payment amount must be less than or equal to the balance."));
  return results;
  }
  
  return results;
  }

• HELP Please: compare timestamps with excel and make the corresponding value in the next column

  Hello

  I have attached the program I did up to now and the txt file required by the program.

  I want to compare the timestamp given by me at the beginning of the program, and when it is true, I want to take the corresponding value of nearby and use for the calculation.

  I am able to compare the time but I do not know how to take the corresponding '0' or '1' value of the file.

  I'm a beginner to labview. It can be simple, but I couldn't understand it

  Kindly help.

  Thanks in advance

  This?  If you get a match, find a true Boolean 1 d array and use the index of the element to get the data of the next column.

  

• variable sharing, missing data, the timestamp even for two consecutively given

  Hello

  I have a problem with missing data when I read a published network shared variable.

  Host VI:

  In a host of VI on my laptop (HP with Windows XP Prof.) I write data to the shared Variable 'data '. Between two consecutively write operations is a minimum milliseconds of wait time. I use it because I want to make sure that the time stamp of each new value of data is different then a preview (variables shared the resolution is 1 ms)

  VI target:

  the VI target cRIO-9012 bed only of new data in the way that it compares the timestamp of a new value with the time stamp of the last value on a device in real time.

  Problem:

  rarely, I'm missing a data point (sometimes everything works fine for several hours, transfer thousands of data correctly above all of a sudden failure occurs). With a workaround, I'm able to catch the missing data. I discovered that the missing data have the timestamp exactly the same, then the last point of data read, is so ignored in my data 'legal '.

  To summarize, the missed value is written to the variable shared host, but ignores the target because its timestamp is wrong, respectively the same as the last value, despite the host waits for a minimum of 10 milliseconds each time before writing a new value.

  Note:

  The shared Variable is hosted on the laptop and configured using buffering.

  The example is simple only to display the function of principle, in real time, I also use a handshake and I guarantee that there is no sub - positive and negative.

  Simplified example:

  

  

  Question:

  Anyone has an idea why two consecutively data can have the same timestamp?

  Where timestamping (evil) Finally comes (System?)?

  What would be a possible solution (for the moment with shared Variables)?

  -> I tried to work around the problem with the clusters where each data gets a unique ID. It works but it is slower that comparing the timestamps and I could get performance problems.

  It would change anything when I animate the shared on the RT System Variable?

  Thanks for your help

• How to trace the greatness of the variables compared to the timestamp with evenly spaced samples in time?

  Hello world. I need to trace the variable amplitudes compared to the timestamp (date and time), but the time intervals between samples are not equidistant. In my area, this is called trend plot. I'm surprised that Labview does not a vi to do this. The only solution that I found so far is to save the data in an Excel file and open this chart in Excel because it has the ability to trace what that this is against what whatsoever is not limited to something as even spaced samples. How to achieve this is Labview? A graph of waveform vi would be perfect if it was not by the fact that it works with even spaced samples.

  Thank you.

  Paulo Siqueira

  Your requirement is directly possible with LabVIEW.

  You can spend time to understand the difference between 'Chart', 'Graph' and "Graph XY".

  VI attached is drawing samples of unequal time.

  Hint:-right click on the 'XY' graph-> properties-> display-> 'Axis of X' = absolute time Format

  Thank you

  You can create an array of timestamps and min/max table compares sets of stamps.

  Use the double conversion for seconds since...
