• How to find the value max and min for each column in a table 2d?

  How to find the value max and min for each column in a table 2d?

  For example, in the table max/min for the first three columns would be 45/23, 14/10, 80/67.

  Thank you

  Chuck,

  With color on your bars, you should have enough experience to understand this.

  You're a loop in the table already.  Now you just need a function like table Max and min. loop.  And you may need to transpose the table 2D.

• Not Null on the column of a primary key constraint

  I came across a table defined in the same way to...
  
  create table t (t_id int constraint nn_t_id not null constraint pk_t primary, data key number);
  
  Of course, the primary key is the is not null, then is there a reason to add the redundant constraint not null?

  There are two parts to your question, I think:

  (1) why add a NOT NULL if a primary key is also reported.
  (2) why is null is NOT a name defined by the user (in this case nn_t_id).

  1 > I think you are right: there is no difference in behavior in the way that Oracle is going to reject the creation of NULL in this column (whether through the direct insert or update with a NULL value). I personally always declares the NOT NULL for columns, I know to never have null, regardless of whether the column is (member of) a PK.

  It's pretty funny, btw, the SQL standard as chosen able to be the NULL default value. I think that we all type much less, if the SQL standard chose NOT NULL default value. But that's another story.

  2 > I don't see given nullability defined by the user of the explicit names now and then, because of some "coding guideline' which dictates that constraint names must never be generated System. This guideline is often presented as a result of the exception handling of "client-side", where the constraint name is filtered SQLERRM and then more personalized to be displayed to the end user. However for NOT NULL constraint violations, I think (does not fully to check) that you are always thrown an ORA-01400 is an ORA-01407. Who nowadays both will tell you exactly (in SQLERRM) which column of this table is currently in violation of a NOT NULL constraint.

• Apex 4.0.1; automatic fire validations not null for full items

  Hello
  
  I have a form with two elements (textarea and select list), where the fire automatic validations not null for these items, they were filled with values.
  Please, advise how to debug.

  Hi Edward,.

  No, they don't. Because the server does not actually know what happens in the browser. And because of security, which should also be separated, because otherwise someone could hide a page element and work around a not null not check on the server.
  So in your case you if the "not null" for a page element is conditional, you must set the indicator required for 'No' and create a regular validation "not null" with a similar condition your dynamic action.

• Can I allow an application for one person on my family share but does not allow for each other?

  Can I allow an application for one person on my family share but does not allow for each other?

  You can't delegate who has access and who doesn't have access to the applications. You can lock devices with age restrictions, so only items appropriate age are at their disposal. Or you can hide your list purchases. The purchased app can then be displayed when you want to share with someone else, then be hidden again once the application is downloaded on their device.

  I hope this helps.

  Replace the double quotes ("") by single quotes ('). If this does not work also, try a location without spaces in the directory name.

• Count of NOT NULL or NOT

  Hi all

  I am trying to run a query to count how many reports in my system have a valid "RunNumber" in a specified amount of time.  To do this, I need to eliminate some bad entries and null values that are entered in the column RunNumber

  My query looks like this:

  Select round (count (a.ReportNumber) / tot_reports * 100, 2) PERCENTAGE

  report a, b of EMS,

  (select count (ReportNumber) report tot_reports, ems WHERE report.id = emss.id and insertdate BETWEEN 1st January 13 'AND January 31, 13')

  where a.id = b.aid and a.insertdate BETWEEN January 1, 13 'AND 31 January 13'

  and (b.RunNumber not in ('0000000000', 'N/a', 'NA', 'NONE', 'NONE GEN"," NOT Available. ","NOT AVAILABLE","NOT PROVID","REFUSAL","DENIED", 'UNK', 'UNK',"UNK.", 'UNK000',

  ("UNKKNOWN", "UNKNOWN", "UNKNOWN", "UNKNOWN", "UU", "XX", "XXX", "XXXXX", "XXXXXX") or b.Runnumber is not null)

  Tot_reports group;

  When I run this query, I get 97.73%

  There are 44 total records and 1 card has a null value, and 3 contain a 'bad data' I'm trying to weed out.  So techincally the % should be 40 files with a 'good' runnumber.  And this percentage 40/44 * 100 = 90.9%

  I know that the null value is shaking the calculation but I don't how to work around it.  Any help will be greatly appreciated.  Thanks in advance.

  Thank you very much.  This helped me wrap my head around what I was trying to accomplish and it worked perfectly.

• Results not updated for each row in BIpublisher

  Hi all I have a Bi publisher report that updates the results of the first line and in the second row to update the results is to choose the values of the first column itself and using the same values for all other lines.
  
  Here is my report format
  
  Months saving altogether, for 30,60,90,120
  Jan
  Feb
  Mar
  
  Total are registered by each month and days shows after 30,60,90,120 how much is still in operation. For example should give an idea of exactly what is happening
  
  For example:
  
  Total 30 days 60 days 90 days 150days 210days 180days 120days
  ------------------------------------------------------------------------------------------------------------------------------------------------------------ Jan saves 330 287 274 270 263 262 259 257
  
  Feb saves 298 255 242 238 231 230 227 225
  
  Mar saves 291 248 235 231 224 223 220 218
  
  
  So what happens is lets say for example there is a total of 330 enrolled in January and after 30days 287 are still active and after 60 days 274 are still in business after 90 270... etc.
  Get active January values correctly.
  
  But in the future when I see the values for February that the total for February is 298 and after 30 days, that do not operate gives me good.
  
  Is subtracting the same amount as jan. looking at the figures it is subtracting
  -43,-13,-4,-7,-1,-3,-2 for Jan who cancel after consecutive days
  It is subtracting the same amount for Feb also but my real cancelled for February is different we 45,12,8,9,2,2.
  It does the same thing for every month.
  There should be a change in the code. Here is the XSL code used in
  
  <? xdoxslt:set_variable($_XDOCTX,_'v_SavesCanceled',_SAVES_CANCELED_COUNT)? >
  
  <? xdoxslt:set_variable ($_XDOCTX, 'v_RtSaves', xdoxslt:get_variable($_XDOCTX,_'v_RtSaves') - xdoxslt:get_variable($_XDOCTX,_'v_SavesCanceled'))? >
  
  <? xdoxslt:get_variable($_XDOCTX,_'v_RtSaves')? >
  
  Effectively cancels it should be updated for each line but his picking cancels it even for each month.
  Hope it is clear let me know if you need any additional information
  Any help is appreciated.
  
  Thank you

  You can get these details by setting values for the following parameters (at the level of the session, preferably) before generating the 10046 trace.

• BlackBerry smartphone Email folders do not appear for each new account - available only generic messages folder

  I would like to know if it is possible to obtain new accounts I created to appear in a single folder for each account.

  With my first Blackberry Curve (new) work I managed to set up my personal account via the Web of BIS site and it automatically created a unique record for this account. I attended the Canada on the Rogers network.

  My new job, I have been give a BB used by a previous employee. I've set up two other accounts using the BIS Web site, rather than the BB, and this time no new files have been created. My email all comes in the main folder of Messages. I use a Verizon BB this time.

  
  

  Note, I tried to add another account via the BB Setup Wizard and when I chose to set up a new account I get the message: "Browser is disabled by the it strategy" - I guess that's my company policy not BB and Verizon. However, I was able to set up other accounts via the site of the BIS...

  Thanks for any help you can provide.

  BW

  As JSanders is offline, I'll jump in.

  All this information, I infer that your BB does not get purified of is political when gave you. And the it policy does things that prevent you to do as you wish (including possibly hide e-mail icons). If, as you say, you won't be on their BES, then I suggest go back you to these admins and let them clean the BB correctly to remove the it strategy. Then, you will want to clean totally and completely from the beginning.

  Good luck and let us know!
