• Count the number of records between two values of keys (BTREE)

  How can I count the number of keys between two values?

  I use python driver and BTREE access method.

  = >

  Ideally, what I want is a set of whole time series data (intervals may change) to a given number of points on average. The keys are timestamps and the values are the data that it takes on average. I need to count the number of records between two timestamps so that I can divide this figure by the number of points I need and data on average. What is the best way to do it?  Or should I keep the timestamp constant intervals and use the RECNO access method?

  Thank you
  (first post btw... and why is there not a lot of people at stackoverflow that answering the questions of Berkeley DB?)

  BDB is an integrated db and there no internal counters or statistics you might grap to use for this.    You will have to do it manually.

  You can create a cursor, grap the records you want, whenever you get the next card that you bump a counter.

  If you are using RECNO, you can use a slider to obtain the number of registration (DB_GET_RECNO), and if all that you data is in

  sequentail records with no missing documents, you can find the total number of take the last rec #-original rec # + 1 to get a count.

  If you pass the SQL API, you can issue a SQL query to give you a count.  Select count (*) where...

  As you enter the data anyway, so better perhaps to count records as you go along.

• Scripting: Count the number of selected pixels (non-quadrangle) or alternative approach

  Is it possible to count the number of pixels in a selection that is not a quadrilateral? For example, if I have cntl - click on the thumbnail of a text layer, I would like to know how many pixels is selected.

  This application, if anyone has another approach to try...

  

  My goal is the place the text at some point where it covers do not all lines (or, Alternatively, the place where it covers the smallest number of pixels line). My approach is to insert a text in red to the desired location, apply a BlendMode.Multiply to the text. The number of Red pixels always on the screen will show how many pixels line I'm concealing. Then I move the text into a region and check the histogram in 76 index (which is 255,0,0), find the point with the highest number of red (meaning concealing pixels less line) and finally move the text at that location. See the code snippet below:

  var bestCX = cX;

  var bestCY = cY;

  var bestPixelDensity = - 1;

  var pixelDensity = 0;

  var searchRegionWidth = 3000;

  var searchRegionHeight = 2000;

  loop through an area 3000 x 2000 around where you want

  for (var x = cX - searchRegionWidth/2; x < cX + searchRegionWidth/2; x ++)

  {

  for (var y = cY - searchRegionHeight/2; y < cY + (searchRegionHeight/2); y ++)

  {

  textItemRef.position = new Array (x, y);

  pixelDensity = myDocument.histogram [76]; index of 255,0,0 (red)

  If this point is greater than the previous highest density, use it instead.

  if(pixelDensity > bestPixelDensity)

  {

  bestCX = x;

  bestCY = y;

  bestPixelDensity = pixelDensity;

  }

  }

  }

  move text in the best location found

  textItemRef.position = new Array (bestCX, bestCY);

  The problem is that the images I use are very large ((7000x7000px) for each histogram control takes a few seconds and I really need to move in a fairly large region (3000 x 2000) to find the best place.) I think that it is perhaps faster if I'm not using the histogram at all, and instead each time that I move the text, I select the text and see how many points is in the selection. Any help or alternative approaches would be great!

  I don't know the answer, the only thing I can think is the whole of the histogram to the selection and treatment of the histogram of the selected area.

• SQL to count the number of days of January with a range of dates

  I have data like this, how to calculate the number of days with January in this date range.

  BEGINNING	END	DAYS OF JAN
  12/12/2013	20/01/2014	20
  21/01/2014	02/02/2014	11

  Hello

  So, you want to count the number of days between

  (a) either start_dt, or January 1, 2014 (prevailing later) and

  (b) or end_dt or January 31, 2014 (whichever comes first).

  However, if start_dt and end_dt are prior to January 2014 (or both are later) which will result in a number negative if you take the difference or 0, if it is higher.

  This looks like a job for the GREATER and LESS than functions.

  SELECT start_dt - START is not a column name good

  , end_dt - is neither END

  BIGGER (1 + LESS (end_dt, DATE ' 2014-01-31'))

  -Most GREAT (start_dt, DATE '' 2014-01-01)

  * v

  ) AS jan_days

  FROM table_x

  ;

  If you would care to post CREATE TABLE and INSERT instructions for some examples of data, then I could test it.

• Count the number of fields in a record of CSV file

  Hello
  
  Here's my problem. I need to open a CSV file on a directory and to count the number of fields in a record. I can easily read the first record using the package UTL_FILE, something like:
  
  UTL_FILE.fopen (s_remote_dir, s_csv_file, 'R', 32767);
  UTL_FILE.get_line (input_file, buffer_entree);
  
  then I count the number of commas in the buffer in order to get none. fields:
  
  IF buffer_entree IS NOT NULL THEN
  n: = < function that counts the number of commas in a string, buffer_entree >
  END IF;
  
  However, this method will not work If a comma is present within a field, that is to say:
  
  127763, account "TRA", 1001, 34, _ "1007 main St., apt. 798 "_"
  (last field contains a comma)
  
  Please notify.
  
  Kind regards
  M.R.

  Here is an example of regexp Etbins solution:

  SQL> declare
    2     line     varchar2(1000) := '127763, "TRA account", 1001, 34, "1007 main St., apt. 798", 42, "This, and that, and more"';
    3     fields   number;
    4  begin
    5     fields := regexp_count(regexp_replace(line,'".*?"'),',') + 1;
    6     dbms_output.put_line('Number of fields: '||to_char(fields,'TM9'));
    7  end;
    8  /
  Number of fields: 7
  

  Edit:
  Added the '+ 1', because the number of commas is a less number of fields ;-)

• How to count the number of data records?

  Hey guys, how to count the number of records, I had on a data object variable?

  Im having a result of sql query in a variable like this:

  oDB.resolveNode("#command").query.select.value = "SELECT * FROM Customers WHERE CliNombre LIKE ' % ' + input1 +" %' ";

  oDB.open ();

  oDB.first ();

  So I need to count the number of records retrieved by this SQL query at the moment. Help please

  Then move the cursor back to the first record after you have your account.

  There is a keyword count in SQL that will allow you to get the account of your request. You can run that first - get your account, and then run the actual query to get the Recordset. This would require a separate data connection. Some examples of code.

  var xfa.event.newText = inName;
  If (inName == "") {}
  App.Alert ("you must enter a name--try again!")
  }
  var nIndex = 0;
  While (xfa.sourceSet.nodes.item (nIndex) .name! = "DataConnection2")
  {
  nIndex ++;
  }

  oDB = xfa.sourceSet.nodes.item (nIndex) .racing var (1); pertaining to the specified data connection node
  App.Alert (ODB.saveXML ("Pretty"));

  var nIndex = 0;
  While (xfa.sourceSet.nodes.item (nIndex) .name! = "DataConnection3")
  {
  nIndex ++;
  }
  var oDBCount = xfa.sourceSet.nodes.item (nIndex) .racing (1); pertaining to the specified data connection node
  Configure sql call DB to get the number of records that match the criteria

  oDBCount.nodes.item (1).query.setAttribute ("text", "commandType");
  oDBCount.nodes.item (1).query.select.nodes.item (0) .value = "Select count (*) from table1 where AcctNumber = '" + inName + "'";
  oDBCount.open)
  oDBCount.close)

  Configure sql call DB to get the specified employee number

  oDB.nodes.item (1).query.setAttribute ("text", "commandType");
  oDB.nodes.item (1).query.select.nodes.item (0) .value = "Select * from table1 where AcctNumber = '" + inName + "'";
  App.Alert (ODB. Nodes.Item (1) .saveXML ("Pretty"));

  now connect to the DB and get a recording
  oDB.open)
  oDB.close ();

  Note the SQL command use the keyword count (take a look at the oDBCount section). This will return a number of return to the cllaer. When I set up the data connection, a node count (*) that appeared there. I dragged to the form and it has created a field called count that the onus at this node. When the query is executed, the number of resulting records returns to this field. You can have hidden it so that your users can not see it and also to change the binding votes to zero, so it is not included in the data file that is submitted when the form is complete.

• How to count the number of conditionally highlight cells in a column or row

  I'm working on a table to identify problems with my credit rating. So, I have a column that indicates the due date on the invoice and G that contains the date to which I made the payment.

  I'm trying to follow how many times I'm late with payments. I want to improve.

  So if the G column is later than column D, both with the Date formatting. So, now I've highlighted cells and I want to summarize for the year, how many times I was late payments.

  I thought a column G to count the number of days before or after that back I was with payments. But if the sum, it only gives me no useful information. I guess I could count the number of cells with values less than 0.

  I prefer to be able to put in the summary column for G something that said 0-12 years ago has highlighted cells in the column.

  Thank you

  You can not count based on sharing or formatting.  You can, however, be based on the same conditions.

  There are functions:

  COUNTIF() counties based on a condition is true

  and

  COUNTIFS() based on several conditions being true

  = NB. If

  Here is a way.  IT will take an additional column that calculates the "delay" in the days of a payment

  

  the first two lines are the lines of header

  H3 = IF (COUNTA (D3, G3) > 1, MAX ((G3−D3) DUR2DAYS, 0), "")

  It's shorthand dethrone select cell H3, and type (or copy and paste it here) the formula:

  = IF (COUNTA (D3, G3) > 1, MAX ((G3−D3) DUR2DAYS, 0), "")

  Now select cell H3, copy

  Select the H3 cells at the end of column H, dough

  H1 = "payments late =" & COUNTIF(H,">0")

• Count the number of 1 is present in digital waveforms obtained by converting the pulse signals.

  Hello

  I use Analogtodigital.Vi to convert the pulse of the sequences in digital.signals.I am able to get the representation of digital waveforms of impulses.

  But how to count the number of 1 is present in the converted digital waveform. I want to count the number of 1 is present in the digital waveform converted.

  Thanks in advance.

  Have you tried the block scheme of similar to the Digital.vi of opening?

  It creates an array 2D uncompressed 1 and 0, which is the binary 16 bits A/D conversion of each element in the array Y of the input waveform. You can use the DWDT digital Array.vi Boolean to convert a 2D Boolean table. Then convert Boolean values to 1.0 and summarize the array of integers. The sum must be the number of 1 bits in the digital waveforms.

  Note: The VI attached is saved in version 8.6. When I have it saved for the previous Version a warning was generated about the possible differences in the versions. Let me know if it doesn't work, and you are using which version of LV.

  But my requirement is: it must count the update only when it detects a different value from array. When it detects a different value in the table must be updated and count it and if the update of the table value is similar the TI should not count it.

  For example, if the V_PROCESS_RATE table have these 3 values (10,20,30) and we need to update these 3 values with (10,40,50), so no update, it should return is 2 not 3.

  Thank you

  And then don't update these lines, change your update statement

  UPDATE HOSPITAL_SUBSERVICE_PROCESS M
  SET M.PROCESS_CHARGE=V_PROCESS_RATE(i)
  WHERE M.HOSPITAL_ID=V_HOSPITAL_ID
  AND M.HOSPITAL_PROCESS_ID =V_PROCESS_ID(i)

  Hello world

  Warm greetings

  I'm using Oracle 11 g. I want to count the number of updates inside a loop. If updating not only one value in the table, then it should return 0 otherwise, it should count the number of updates and return it. I used SQL % ROWCOUNT, but returning an incorrect value.
