• SQL-MIN() don't not returns the minimum value

  This is my code;

  $SQLx = "SELECT MIN (price_from) AS minimumprice FROM AN_pricetable WHERE accomm_id =". "." $db_field ["accomm_id"];

  $resultx = mysql_query ($SQLx);

  $pricefrom = mysql_result ($resultx, $i, 'minimumprice');

  If ($pricefrom == 0) {}

  $pricefrom = 'TBC' ;}

  But for some reason, it is not the minimum value "price_from". For example, several rows in the table have the same "accomm_id", and their values in the field 'price_from' are: 8, 12, 50-7, but the SQL code returns the MIN 12. What I'm doing wrong here?

  Thank you

  What is the data type of price_from?  If it is a type of string (char), then 12 would be the lowest value.

• PL/SQL loop to find the minimum value

  I want to find the minimum value from a table using the pl/sql loop

  I have data format below.

  Thanks in advance

  Why PL/SQL? SELECT MIN (SAL) OF TEST will be more rapid and much less coding. In any case:

  declare

  number of v_min_sal;

  Start

  for v_rec in a loop (select sal from emp)

  If nvl (v_min_sal, v_rec.sal + 1) > v_rec.sal

  then

  v_min_sal: = v_rec.sal;

  end if;

  end loop;

  dbms_output.put_line (' lowest salaray is "' |") v_min_sal | '"');

  end;

  /

  The lowest Salaray is "800".

  Hello

  Aggregate functions reduce the result set with one row per group.
  Almost all of the aggregate functions are homologous analytics that can give the same results without restricting the result set. Since you want the output to contain several lines per group, then the analytic functions are probably better for you.

  Here's one way:

  WITH      got_analytics     AS
  (
       SELECT     name, org, desig, salary, year
       ,     MAX (salary)  OVER ( PARTITION BY  name, org, desig)          AS max_salARY
       ,     ROW_NUMBER () OVER ( PARTITION BY  name, org, desig, salary
                                  ORDER BY        year  DESC
                         )                              AS year_num
       FROM    emp
  )
  SELECT     name, org, desig, salary, year
  FROM     got_analytics
  WHERE     salary          = max_salary
  AND     year_num     > 1

• Return multiple values from a table

  Hi there I'm working on a bit of sql that returns values when they exist in a table.
  The code I have returns the correct value when there is an entry in the tbl_studentmodules table, as soon as there is more than one entry in this table it does display no line at all: (.)
  
  Can someone tell how to return multiple values?
  
  

               select modulename from tbl_modulefeedback
  where 1 = (select count(*) from tbl_studentmodules
         where upper(:APP_USER) = upper(student_id))
  and 1 = (select count(*) from tbl_modulefeedback, tbl_studentmodules
        where tbl_modulefeedback.modulecode = tbl_studentmodules.modulecode)

  Thanks in advance!

  Try this:

  select modulename
  from tbl_modulefeedback
  where 1 <= (select count(*) from tbl_studentmodules
         where upper(:APP_USER) = upper(student_id))
  and 1 <= (select count(*) from tbl_modulefeedback, tbl_studentmodules

• PARTITION OF? Returns an identifier based on the minimum value of another column

    select dst_id
    from t
    where dst_title = 'abc' 
    and edition_from = 1
    and media_item = minimum value of media item using above where clause

  Return dst_id = 1 because it has the value point minimum media 1 where dst_title = abc and edition_from = 1
  
  Is this possible in 1 query? I tried using partition and on dst_title, edition_from, but it does not work.
  
  I am currently using a query sub or 2 queries, but think that there must be a way to do it in a?

• Take the minimum value for table data

  I'm storing test data in a table, with the hope that I can output the minimum value of the data. So far, I have used the table of max/min but can't make it work how I want. The test runs continuously in a loop of the holder. I get the minimum values in the table, but I would like to change the number of samples that the table contains, before it generates a minimum. The other option is that I run the test for a period of time (e.g. 3 seconds) and the table stores the data for this time then output 1 minimum value for the entire period.

  My current configuration VI is attached.

  Very appreciated

  Chris

  The size of the array in your VI is determined by the number of samples that you collect in your DAQ assistant, who is now 100 samples.  Never more, never less.

  How many samples do you want before you determine the minimum?

  Maybe what you really want to do is to build the table in the while loop and store it in a shift register, and when the loop has repeated enough times, then you take the minimum of built table.

• Error when setting the minimum value of entry number Spin Box...

  Hai
  I drag and drop a VO and created a table. In this table, I cast a column that contains an InputText field to entry number Spin Box. During loading of the page, the table retrieves data from the database and display of numerical values in the SpinBox.After who, when I scroll the table through vertical scroll bar, the table * "data extract" * and error began as * "the value must be the number" *... In the original Version, this attribute is a number.
  THIS ERROR will PRODUCT ONLY when I put the minimum value of the counter... The purpose of minimum value, I want only the user to select the value of ve only... How can I prevent the user to select only values of ve... ? (IE, * how to set the minimum value of counter?) *

  Try changing the data type of your attribute in the EO to be Double instead of number.

• Returns the lowest value of two fields

  Hello

  I have two domains that users manually enter in a form.  Value1 and Value2.

  Someone at - it suggestions on the best way to use JavaScript to return the lowest value of the two fields?

  Thank you

  Natalie

  I think I misunderstood what you mean by any, I thought you wanted the calculated value to be None. The two fields value digital formats and modify the script for:

  Custom calculate script

  (function () {}

  Initialize the array

  aNums var = [];

  Get the field values as strings

  var s1 = getField("Value1").valueAsString;

  var S2 = getField("Value2").valueAsString;

  Convert values to numbers if not empty and add to the table

  If aNums.push(+s1) (s1);

  If aNums.push(+s2) (s2);

  Set the value of this lesser field of entries

  If both are blank, this field blank

  Event.Value = aNums.length? Math.min.Apply (null, aNums);:

  })();

• Question of value Popup Lov key (description of the poster, returns the key value) by default

  Hello
  
  I have a Popup Lov key (description of the poster, returns the key value) and I want a default value. It is based on a list (user name, id).
  I tried to put the id of the user logged on as default, but what I see on the screen in the field is the value of the id, not the username.
  How can I pass the user id and see the user name?
  
  Thank you.

  Oh! My bad, I thought you are talking about regualt lOVs not popups.

  OK, so that's what you need to do, I tried it and it worked for me:

  your popup LOV > default > type: body of the PLSQL function > and enter a query like:

  declare
  UID number.
  Start
  Select user_id from the uid of the user
  where UPPER (username) = UPPER(:APP_USER);

  This should show username and retune userid.

  Hope this helps,

• : Nom_element and V ('ITEM_NAME') do not return the same value

  Hi all
  
  I'm developing a shared application process that is called by an AJAX request.
  
  For the pl/sql code, stored procedure validation e development support I moved the logic inside a database.
  So I have this situation:
  
  Application process
  
  ...
  : MYITEM: = wwv_flow.g_x01; -received setting of ajax call I want to put
  ...
  MY_FUNCTION();
  
  MyFunc
  
  ...
  v('MYITEM') - here I use value MyItem
  ...
  
  The problem is that when I call v ('MYITEM') the value I get is the previous and not one that I put with: MYITEM: = wwv_flow.g_x01;
  I have the same problem if I set the V ('MYITEM') inside the apex application process.
  
  I saw that it worked right if I use the following to set the value of the element in the application process:
  
  APEX_UTIL. SET_SESSION_STATE('P0_LST_DATA',:P0_LST_DATA);
  
  Is this a bug?
  I was expecting to get the value of the item: MONELEMENT and v ('MYITEM') are equivalent...
  
  Thank you
  Davide

  Davide,

  If you encode the block like that, you should get the results you expect:

  : P100_VAR1: = '1'. : P100_VAR1;
  : P100_TEST: =: P100_VAR1;

  The reason why this block does not give you what you expect:

  : P100_VAR1: = '1'. : P100_VAR1;
  : P100_TEST: = v ('P100_VAR1');

  ... is that v ('P100_VAR1') returns the current value of the item in the table of PL/SQL State session as it existed before the execution of the block. The assignment to the variable binding: P100_VAR1 has registered only a value in storage variable to bind the dynamic execution at this time and has not yet spread to session state, which is located at the end of the execution of the block. It's a little weird, we know.

  Andy,

  I figured that the: xxxx points have been settled during the loading of the page with what the source is...

  They contain the session state value and can be read or written in notation variable bind.

  However, they are updated only in the session when you send page...

  They are updated in session state when the particular block is completed and a commit is issued at this time there.

  In order to update a piece of code PL/SQL session state, you must use... apex_util.set_session_state.

  You must be careful to call it when scoring also bind variable to set the session state may cause one to deny the other. Using one method or the other should work very well.

  kindly tell how to use the unique value of a table with the index 0

  Hi
  
   
  
  Yep, use Index Array as Gerd says. Also, using the context help ( + h) and looking through the array palette will help you get an understanding of what each VI does.
  
   
  
  This is fundamental LabVIEW stuff, perhaps you'd be better spending some time going through the basics.

• What is the minimum value for the data type double?

  ... a more academic question: what is the minimum value of the data type double? I thought 'double', it is the 8-byte IEEE standard and what I remember, it's + - 1.7E + - 308.  The more different number of 0 should be 1.797E - 308.

  This is why I was a little surprised when I looked at the data output of my calculation of CVI, where I found the numbers with exponents of E-319 or E-324 as the smallest value...

  But I'm sure there's an explanation :-)

  Thank you for sharing with me,

  Wolfgang

  The largest number is indeed the order of + 1.7E + 308; There are a smaller number of - 1.7E + 308. Note that this is in fact the most negative number, which is the smallest by some reckoning. For the small beach of the Exhibitor, things get a little more complicated. 1E-308 can be represented with complete accuracy and resolution, but if you're willing to lose a few bits of precision, you can go down even further. For example:

  Double x, y, z:

  x = 1E-300;

  y = 1E7;

  z = x / y;               Give 1.000000000000000E - 307

  y = 1E8;

  z = x / y;               Give 9.999999999999999E - 309

  y = 1E18;

  z = x / y;               Give 9.999987484955998E - 319

  y = 1E23;

  z = x / y;               Give 9.881312916824931E - 324

  So, as you can see, values less than 1E-308 are possible, but they become increasingly more inaccurate and should not be relied upon.
