• Select only records where the column values are not all equal to zero

  Hi everyone, it seems so easy, but it has left me speechless on the research in a way that is clean, easy to achieve. I know when someone replies, I'm going to kick me. So, let's assume this is what I have:
  

  with mytable as (
  select 'Type 1' as itemtype, 'JAN' as monthname, 0 as theval from dual union all
  select 'Type 1' as itemtype, 'FEB' as monthname, 1 as theval from dual union all
  select 'Type 1' as itemtype, 'MAR' as monthname, 5 as theval from dual union all
  select 'Type 1' as itemtype, 'APR' as monthname, 1 as theval from dual union all
  select 'Type 1' as itemtype, 'MAY' as monthname, 4 as theval from dual union all
  select 'Type 1' as itemtype, 'JUL' as monthname, 0 as theval from dual union all
  select 'Type 1' as itemtype, 'AUG' as monthname, 0 as theval from dual union all
  select 'Type 1' as itemtype, 'SEP' as monthname, 1 as theval from dual union all
  select 'Type 1' as itemtype, 'OCT' as monthname, 7 as theval from dual union all
  select 'Type 1' as itemtype, 'NOV' as monthname, 1 as theval from dual union all
  select 'Type 1' as itemtype, 'DEC' as monthname, 2 as theval from dual union all
  
  select 'Type 2' as itemtype, 'JAN' as monthname, 0 as theval from dual union all
  select 'Type 2' as itemtype, 'FEB' as monthname, 0 as theval from dual union all
  select 'Type 2' as itemtype, 'MAR' as monthname, 0 as theval from dual union all
  select 'Type 2' as itemtype, 'APR' as monthname, 0 as theval from dual union all
  select 'Type 2' as itemtype, 'MAY' as monthname, 0 as theval from dual union all
  select 'Type 2' as itemtype, 'OCT' as monthname, 0 as theval from dual union all
  select 'Type 2' as itemtype, 'NOV' as monthname, 0 as theval from dual union all
  select 'Type 2' as itemtype, 'DEC' as monthname, 0 as theval from dual
  )
  select
    itemtype,
    sum (case monthname when 'JAN' then theval else 0 end) as JAN,
    sum (case monthname when 'FEB' then theval else 0 end) as FEB,
    sum (case monthname when 'MAR' then theval else 0 end) as MAR,
    sum (case monthname when 'APR' then theval else 0 end) as APR,
    sum (case monthname when 'MAY' then theval else 0 end) as MAY,
    sum (case monthname when 'JUN' then theval else 0 end) as JUN,
    sum (case monthname when 'JUL' then theval else 0 end) as JUL,
    sum (case monthname when 'AUG' then theval else 0 end) as AUG,
    sum (case monthname when 'SEP' then theval else 0 end) as SEP,
    sum (case monthname when 'OCT' then theval else 0 end) as OCT,
    sum (case monthname when 'NOV' then theval else 0 end) as NOV,
    sum (case monthname when 'DEC' then theval else 0 end) as DEC
  from mytable
  group by itemtype
  order by itemtype

  I need an external application around it or something which will select only 'Type 1'... that is, if all months are each equal to zero, do not include the record in the result set.
  
  In summary to get a total of zero is not an option, because I could have-15 and + 15 in different columns, in which case, the recording should be displayed.
  
  Something as simple as... 'not the case (oct = 0 and 0 nov and dec = 0...) at the end is all it seems to me necessary. I thought to add a case for each column clause, but that seems not very effective. Ideas?
  
  Thanks in advance!

  )
  order of itemtype
  {code}
  
  Change again... OK, I guess that I am answering my own question here, but I think that by using a WITH to write the main request once clause and then selecting * twice using the MINUS operator between where the second query is where (oct = 0, etc.) is what I need. If anyone has better suggestions, please let me know! Here's the logic of nickname for what I come up with to date...
  
  {code}
  WITH mainquery as (select all)
  Select * from mainquery
  less
  Select * from mainquery where (oct = 0, nov = 0, etc...)
  {code}
  
  Thanks again!

  Hello

  You can do it with a HAVING clause:

  select
    itemtype,
    sum (case monthname when 'JAN' then theval else 0 end) as JAN,
    sum (case monthname when 'FEB' then theval else 0 end) as FEB,
    sum (case monthname when 'MAR' then theval else 0 end) as MAR,
    sum (case monthname when 'APR' then theval else 0 end) as APR,
    sum (case monthname when 'MAY' then theval else 0 end) as MAY,
    sum (case monthname when 'JUN' then theval else 0 end) as JUN,
    sum (case monthname when 'JUL' then theval else 0 end) as JUL,
    sum (case monthname when 'AUG' then theval else 0 end) as AUG,
    sum (case monthname when 'SEP' then theval else 0 end) as SEP,
    sum (case monthname when 'OCT' then theval else 0 end) as OCT,
    sum (case monthname when 'NOV' then theval else 0 end) as NOV,
    sum (case monthname when 'DEC' then theval else 0 end) as DEC
  from mytable
  group by itemtype
  HAVING      MIN (theval)     != 0
  OR      MAX (theval)     != 0
  order by itemtype
  ;
  

  If the values are all 0, then the MIN and MAX will be 0.
  If the MIN or MAX is not 0, the values are all 0.

  This assumes that the combination (itemtype, monthname) is unique, because it is in your sample data.
  If this is not the case, start with a subquery that GROUPs BY itemtype, monthname, so that when you get to the main request, this combination will be unique.

  I want this (area 1) to be nulled out when it is equal to zero. can someone please help?

  Also, when I divide 2 field by field 1, it calculates, but I always get an error message when you open the PDF file. Is it because the field 1 is equal to zero (and you cannot divide by zero)?

  

  I want to zero in the intermediate zone to not appear. Any help is appreciated. I can't understand.
  

  To get rid of the zero you just put an if statement into something like (in formcalc):

  If ($ == 0) then

  $ = ""

  endif

  You do the same thing for the calculation with the error:

  If (Field1 <> 0 and Field1.isNull == 0) then

  $ = Field2 / Field1

  endif

• Select the value equal to the table

  I use Dreamweaver CS5 with PHP and a MySQL database.  I'm reading from a table (states []) in the database that list all States an entrepreneur might work to, that is, WA, ID, OR... my record of the insert is savaing my table with the abriviations of State with the coma in the meantime without space, which is fine with me.  My code for the insert recording is:

  If (isset($_POST['states'])) {}

  $_POST ['States'] = implode (',', $_POST ['states']);

  } else {}

  $_POST ['States'] = null;

  }

  To test what must be my result, I tried to hard-code the value for area WA selection that selects the WA (Washington) very well in the dynamic list/Menu. The checkbox allow multiple selections is selected for this list/menu.  When I try to hardcode several States like WA, ID, nothing is selected.  I also tried selecting WA ID and WAID.  What is the correct format of the select value equal to in order to select multiple items.

  Once the coding is figured out I was going to try to understand how to navigate in PHP and do select dynamically recording and echo (or otherwise print) in the right format for several States in the table would be selected.  However, if anyone out there has a sample, that would be great.

  Thank you in advance for your help!

  First and perhaps that I read it wrong, but 'implode' in your example should not "explode" because you have the array, but you want to get the values out of it?

  Now I know that my next suggestion is not what you want to hear, but I used to think like you and store things in a table, a table in a loop and then try to check the loop if some values exist.  However, as time has taught me it is not necessarily the best way to store values you need for this type of proceeding.  Most of the time in cases like this, your username will seek entrepreneurs in a specific State.  So what I recommend is to create another table with 2 columns:

  contractor_id (a way to identify the contractor, it will be a primary key, which will connect a key for the "contractor_id" in your original table)

  contractor_state (this allows to link an id to a State)

  A single loop would be to query the status of the contractor, the contractor ID is filled and you can run a join to remove the door contractor while the ID condition is met.  The flip side is to get all the contractor IDs meet the criteria of the State.  You must perform a JOIN on the request to combine the original with this new table table if you want to remove the name of the contractor as well as the State didn't give one example.

  Perhaps a good article that you want to read is the first response of this StackOverflow question and the link in the response are talking about standardization and serialization of data:

• values of temperature at high fixed values

  I have two 1102/1302 with 6363 which worked well in the past.  After some downtime, I ran the vi and does not have the correct values.  I studied the virtual channels in MAX and the table has high values fixed for all channels (218-219 C) at room temperature and they are static values.  It would seem that these values are not be played from any connected TCs.  No idea as to what might cause this behavior?

  I found the question late yesterday and it turned out to be a hardware problem.  The problem is now resolved.

• Regulator PID very slow to reach the value Point and zeros process Variable when it should not

  Hello

  I am using a PID controller to regulate the emission of a filament current in an ion gauge, but I'm running into several problems.

  The first and less important, are the controller of PID VI takes at least 5 minutes to get the current where it needs to be.  Is it possible to speed this up?

  The second and more important, are that the PID controller tends to zero the process variable before you start the process of getting the close process of the target value variable.  This can be seen in the attached VI: I write 5.8 volts voltage filament - something I did at the beginning to try to get the controller PID for the process close to the target faster - value variable but when the PID controller starts to do his thing, he kills the tension before anything, rather than rise of 5.8 V.

  The attached VI is a single which has these problems.  VI actual ion gauge controller I've written has the same problems, but in a form even more frustrating.  I have a while loop set up for the filament voltage to where it should be (using a PID controller) first and foremost, then a loop of data acquisition, which also includes a feedback loop in the form of a PID regulator to maintain the filament voltage.  When the second PID controller starts to run, it concentrates the tension that the earlier had set, taking another 5 + minutes to reach the point where we can take data and giving us 5 minutes of false data in the process!

  Does anyone know why PID controllers are behaving like this, and what can I do to fix/work with this behavior?

  Hello

  It seems that PID VI will always be 0 for the first iteration. You can, however, use the advanced PID VI and set up the first iteration in manual mode. After subsequent iterations, you could then define this automatic mode and there will be a transition smoothly. I think this will give you the desired behavior.

• empty value unless calc = zero?

  Hi all

  I'm stumped on a form to fill out PDF when I have a simple calculation, say for example, A + B = C, where A and B are fields to fill in, and C automatically calculates what the answer would be.

  I would like to know if there is a way to C empty unless a and B are zero - in other words, is it possible to do C empty if A and B have not yet been filled, but once they are filled, do show regardless of the answer, even if it is zero? I get a lot of "if (event.value == 0' whenever I google for an answer, and really I don't want an empty field when the other fields are not filled helps in... !

  Thank you!

  Of course it is. Just to get the field values of A and B as strings and see if once are empty and only set the value of the field if they are not. The barebones script would look something like:

  (function () {
  
      // Get the field values, as strings
      var v1 = getField("A").valueAsString;
      var v2 = getField("B").valueAsString;
  
      if (v1 && v2) {
          event.value = +v1 + +v2;
      } else {
          event.value = "";
      }
  
  })();
  

  This could be simplified to just:

  (function () {
  
      var v1 = getField("A").valueAsString;
      var v2 = getfield("B").valueAsString;
  
      event.value = v1 && v2 ? +v1 + +v2 : "";
  
  })();
  

  Replace 'A' and 'B' in the code with the actual names of the input fields.

  The v1 + and + v2 converts strings to numbers so that you get a digital addition instead of string concatenation

• ORA-01476: divisor is equal to zero

  Hello
  To avoid the error oracle ORA-01476 (in sql, pl/sql not) I check the divider first - so it don't not to zero - and then make the division.
  For example:

  with sample_data(n1, n2) as
  (select 6, 4 from dual union all
   select 8, 0 from dual)
   select case when n2<>0 then n1/n2 else 0 end
    from sample_data
  

  Is there another way to avoid division by zero error?

  
  I ask this question because, recently, I've been faced with a situation in which I got a part of the SQL like this:

  ...
  case when dxy+dey+kty+kay-kts<>0 then round(100*(ypol/ sum(case when eidos<>'1' then dxy+dey+kty+kay-kts  end) over(partition by ylik_cd)) 
  .....
  

  But if I had a requirement that multiple "when" conditions should be included - as the divider - writing which precedes
  solution would be complex and prone to errors (in which case I forgot a "when" clause). For example if I had:

  .....
  round(100*(ypol/ sum(case when eidos='1' then dxy+dey+kty+kay-kts when eidos<>'1' and dxy=0 then dxy+dey+kty+kay end) over(partition by ylik_cd))
  .......
  

  
  Note:
  I'm using OraDb 11 g v.2

  Hello

  Instead of

  CASE

  WHEN n2 <> 0

  THEN n1 / n2

  0 OTHERWISE

  END

  You can tell

  N1 / NULLIF (n2, 0)

  This returns NULL when n2 = 0, which is probably less misleading: return 0 in fact resemble the division could be made and n1 = 0.

  If you really want to return 0 if n2 is ZERO, then

  NVL (n1 / NULLIF (n2, 0))

  0

  )

  Unlike the CASE expression, this returns 0 when the n1 or n2 is NULL.

  If you really want the same results as the CASE expression gives you, then the CASE expression is the best way, i.e. repeat n2.  If n2 is a complicated expression, then you can calculate it in a subquery, so all you have to repeat in the expression BOX (in the Super-requete) is his name.
