  Hello Nri,

  What value does P18_SCHOOL_ID?
  If you look at the State of Session (toolbar) developer. If that does not have a value, it's your problem.

  You can create a calculation before the process that gives the correct value. (In one case more often, you have a report and when you click on the link change that id is activated and you see the recording in your form)

  Top query runs too slowly on the real data set. Is there an effective way to rewrite the query which can perform the dough?

  Any help or suggestion would be appreciated

  Thanks in advance

  At the time where the application may not throw anything until after he has retrieved and grouped all the ranks of zone_view. His estimate of 7.5 minutes to scan millions 639 lines really fast enough - it's 85 million lines per minute.

  This seems to be where the time went. The only way that the query can be accelerated is to recover some of the conditions that must be applied before the grouping. The only obvious possibilities for this are

  (a) filter values of zone_num

  (b) move the audit only

  NOT EXISTS (SELECT null from warehouse w WHERE w.zoneid = zrn.zoneid AND w.zone_createdate = zrn.zone_createdate AND w.dt_warehouse IS NULL)

  within the group, because this condition is applied regardless of the values in calculated fields. The AREA ID, ZONE_CREATEDATE are not null, so I suggest to try:

  SELECT ID area, zone_createdate

  Of

  (

  SELECT ID area, zone_createdate,

  MAX (CASE WHEN zone_num = 18 AND tranx_date 'n' IS NOT NULL, THEN 1 TIME zone_num = 18 AND tranx_date IS NULL THEN 0 ELSE-1 END) region_18,.

  MAX (CASE WHEN zone_num = 110 AND not IS NOT NULL, THEN 1 TIME = 110 zone_num tranx_date AND tranx_date IS NULL THEN 0 ELSE-1 END) region_110,.

  MAX (CASE WHEN zone_num = 135 AND tranx_date no IS NOT NULL, THEN 1 TIMES zone_num = 135 AND tranx_date IS NULL THEN 0 ELSE-1 END) region_135,.

  MAX (CASE WHEN zone_num = 140 AND tranx_date 'n' IS NOT NULL, THEN 1 TIME zone_num = 140 AND tranx_date IS NULL THEN 0 ELSE-1 END) region_140

  OF zone_view

  where (IDZone, zone_createdate) NOT IN (select the zone ID, w warehouse zone_createdate WHERE w.dt_warehouse IS NULL)

  and zone_num (18, 110, 135, 140)

  GROUP BY IDZone, zone_createdate

  ) zrn

  WHERE zrn.region_18 <> 0

  AND ((zrn.region_110 = 1) OR (zrn.region_110 = - 1))

  AND (((zrn.region_135 = 1) AND (there IS NOT (SELECT null from warehouse w WHERE w.zoneid = zrn.zoneid AND w.zone_createdate = zrn.zone_createdate AND w.dt_posting IS NULL))) OR (zrn.region_140 = 1))

  OR ((zrn.region_18 >-1) AND (zrn.region_135 = - 1) AND (zrn.region_140)<>

  OR ((zrn.region_110 = 1) AND (zrn.region_135 = - 1) AND (zrn.region_140 <> 0))

  )

  Unfortunately, if the plan of the query time estimates are correct, most of the duration of the query is spent doing a reading zone_view in a full analysis, and which will not be changed by this query.

  If there are many rows for each (IDZone, zone_createdate) zone_view pair, then it is possible that an index on (area ID, zone_num, zone_createdate) would contribute to this request, especially if most (IDZone, zone_createdate) pairs are filtered with the NOT IN (select the zone ID, zone_createdate w warehouse WHERE w.dt_warehouse IS NULL). More radical but probably effective measure would be a functional on index

  zone_view (zone_num, IDZone, zone_createdate, case when tranx_date is null then 0 otherwise 1 end)

  and using the expression in the query box:

  SELECT ID area, zone_createdate

  Of

  (

  SELECT ID area, zone_createdate,

  NVL (MAX (CASE WHEN zone_num = 18 then case when tranx_date is null, then 0 or 1 end end),-1) region_18,.

  NVL (MAX (CASE WHEN zone_num = 110 then case when tranx_date is null, then 0 or 1 end end),-1) region_110,.

  NVL (MAX (CASE WHEN zone_num = 135 then case when tranx_date is null, then 0 or 1 end end),-1) region_135,.

  NVL (MAX (CASE WHEN zone_num = 140 then case when tranx_date is null, then 0 or 1 end end),-1) region_140

  OF zone_view

  where (IDZone, zone_createdate) NOT IN (select the zone ID, w warehouse zone_createdate WHERE w.dt_warehouse IS NULL)

  and zone_num (18, 110, 135, 140)

  GROUP BY IDZone, zone_createdate

  ) zrn

  WHERE zrn.region_18 <> 0

  AND ((zrn.region_110 = 1) OR (zrn.region_110 = - 1))

  AND (((zrn.region_135 = 1) AND (there IS NOT (SELECT null from warehouse w WHERE w.zoneid = zrn.zoneid AND w.zone_createdate = zrn.zone_createdate AND w.dt_posting IS NULL))) OR (zrn.region_140 = 1))

  OR ((zrn.region_18 >-1) AND (zrn.region_135 = - 1) AND (zrn.region_140)<>

  OR ((zrn.region_110 = 1) AND (zrn.region_135 = - 1) AND (zrn.region_140 <> 0))

  )

  This gives a very different plan on my database, by performing an iteration on relevant areas of performance status:

  ---------------------------------------------------------

  | ID | Operation | Name |

  ---------------------------------------------------------

  |   0 | SELECT STATEMENT |              |

  |*  1 |  FILTER                          |              |

  |   2.   VIEW                           |              |

  |*  3 |    FILTER                        |              |

  |   4.     HASH GROUP BY.              |

  |   5.      ANTI NESTED LOOPS.              |

  |   6.       INLIST ITERATOR.              |

  |*  7 |        INDEX RANGE SCAN | ZV_F1 |

  |*  8 |       TABLE ACCESS BY INDEX ROWID | WAREHOUSE |

  |*  9 |        INDEX UNIQUE SCAN | WAREHOUSE_PK |

  | * 10 |   TABLE ACCESS BY INDEX ROWID | WAREHOUSE |

  | * 11 |    INDEX UNIQUE SCAN | WAREHOUSE_PK |

  ---------------------------------------------------------

  Your plan will be different because you have data volumes (I didn't create millions of lines of test data)

  It would be useful to know how many rows there are in the WAREHOUSE, how many distinct (IDZone, zone_createdate) pairs there are in zone_view and the number of rows actually returns the query, and how much is NOT IN (select the zone ID, w zone_createdate warehouse WHERE w.dt_warehouse IS NULL) because these relative numbers determine how these approaches are.

  If there is a table containing all of the (area ID, zone_createdate) pairs which could take place in zone_view, which would have may another possible approach:

  First filter possible pairs against NOT IN (select the zone ID, w warehouse zone_createdate WHERE w.dt_warehouse IS NULL)

  Then attach them to the zone_view to retrieve only the rows in the filtered (IDZone, zone_createdate) pairs.

  Good luck.

  Who will fail in databases, because you assume nls_date_format. How it is difficult to put to_date() surround channels? Rather than play with quotation marks, using one parfile thusly.

  query=table_owner.table_1:"where business_date between to_date('20120505025700 am','yyyymmddhhmiss am') and to_date('20120505025959 am','yyyymmddhhmiss am')"
  query=table_owner.table_2:"where business_date between to_date('20120505025700 am','yyyymmddhhmiss am') and to_date('20120505025959 am','yyyymmddhhmiss am')"
  query=table_owner.table_3:"where business_date between to_date('20120505025700 am','yyyymmddhhmiss am') and to_date('20120505025959 am','yyyymmddhhmiss am')"
  

  You do not have to have all the clauses in a single line, as they are side by side parfile, which would be enough. For this reason parfile is better than the command line in order to avoid all the back-citing dance.

• I don't know how to change the size and quality of the text on the screen on Windows 7

  I just installed a new Windows 7 but I don't know how to change the size and quality of the text on the screen.  I tried all the things normal, resolution, size of icons, dpi etc but nothing gives me what I want.  The text in clear 'wonderful' thing is just terrible.  When I go through the 4 steps I see no text boxes which make the text nothing better.  All options are terrible, so the result on screen is too terrible.  When I do any huge I do not get a full screen of things - view the Start button disappears or I did not closing small cross at the top - of the suggestions to inprove the situation?  I must mention that my screen/monitor is 2006 - I need to buy a new one?  How much is this Windows 7 is going to cost me, or maybe I should go back to XP!

  I sincerely thank all you smart "technicians" for all the answers you always gave myself and all others who ask questions.  I'm not too smart with all this new technology as I fell into it very late.  I am now in my 60s and only started using a pc when I was over 50 years so...  In any case, I asked a question about the size of screen resolution and text and received much good advice from all that you guys.  I had recently changed in XP to Windows 7.  However, the bit of advice that I was given in 'Cyberking' here at the Portugal had set the resolution of the screen, the advanced settings, 75 to 60 Hertz Monitor tab.  Very basic, and the first question asked the technician (Lady) was "what size is your screen?  Naturally as a smaller screen that any 'techno' would be considered dead aid, solving the problem was simple and straightforward without me having to stretch my knowledge and my skills by downloading all programes weird (to me) or do the funny stuff in the bios or something else.  I send this comment to you for you to realize that the simple solution is not always bad and maybe we should go for the easiest first and then work up to the more difficult ones.

  Just for you all to see - now my screen resolution is perfect, the text on the screen is clear and legible without difficulty, even though the size of text and icon is small.  Clarity is all!

  Thank you all once again!   Best regards, Blondie blue.

  Alexandre Gelin says:

  Thanks Karthick_Arp. I use the same method until now, but it's tricky. I don't know how to get the query statistics.

  You can define STATISTICS_LEVEL = ALL at the level of the session

  ALTER session set statistics_level = all;

  You can then run your package

  And then

  Select * from table (dbms_xplan.display_cursor (SQL_ID, null, 'ALLSTATS LAST'));

  This you will get estimated and actual statistics with buffer and reading.

• How to activate the filtering and sorting in a dynamic array

  Hello everyone,
  I'm going crazy with this problem, hope that someone could help me! I have a dynamic array based on a view that changes its application programmatically. For its dynamic nature, I did in my mainPageDef no reference to the attributes of the table:
  
  <>executables
  < variableIterator id = "variables" / >
  < iterator lie = "DLOV_1" RangeSize = "25".
  DataControl = "DLOV_AppModuleDataControl" id = "DLOV_1Iterator".
  R = "always" Sortable = "true" / >
  < / executables >
  < links >
  < Tree IterBinding = "DLOV_1Iterator" id = "DLOV_1" >
  < nodeDefinition Name = "DLOV_10" >
  < / nodeDefinition >
  < / tree >
  < / links >
  
  
  Jspx page I have:
  
  
  < af:table value = "#{bindings." DLOV_1.collectionModel}.
  var = "row".
  lines = ' #{bindings. " DLOV_1.rangeSize}.
  emptyText = "#{bindings." DLOV_1.viewable? "{'No data to display.': 'Access Denied.'}".
  fetchSize = "#{bindings." DLOV_1.rangeSize}.
  rowBandingInterval = '0 '.
  filterVisible = "true" varStatus = "vs."
  selectedRowKeys = ' #{bindings. " DLOV_1.collectionModel.selectedRow}.
  selectionListener = "#{bindings." DLOV_1.collectionModel.makeCurrent}.
  rowSelection = "single" id = "t1" >
  < af:forEach elements = "#{bindings." DLOV_1Iterator.attributeDefs}.
  var = 'def' >
  < af:column headerText = "#{def.name} '"
  sortable = "true" id = "c1".
  filterable = 'true '.
  filterFeatures = "caseInsensitive" >
  < af:outputText value = "#{row [def.name]}" "
  ID = "ot1" / >
  < / af:column >
  < / af:forEach >
  < / af:table >
  
  
  which works really well with the code of my bean (the one who changes the query and execute it):
  
  
  If (am.findViewObject ("DLOV_1")! = null) {}
  am.findViewObject("DLOV_1").remove ();
  System.out.println ("off");
  }
  ViewObjectImpl dLovView = (ViewObjectImpl) am.createViewObjectFromQueryStmt ("DLOV_1", (String) qryTxt.getValue ());
  dLovView.executeQuery ();
  AdfFacesContext.getCurrentInstance () .addPartialTarget (lovTable);
  
  
  Now the problem is I can't get the functionality of filtering and sorting of column. How can I achieve that? I noticed that you define the defName in the nodeDefinition to provide a 'model', but I can't do that because my table does not have a fixed structure.
  Is there a solution?
  Thanks in advance!

  You can pass me the sample, will take a look - use the same mail id that you will find my profile

• How to use the capture and the print button

  I tried to figure out how to use the capture and the "print" button, or add or what you call. I press it and the whole page of a different color changes, so I try to cut the section I want but I don't know how to send it to the printer. Can someone help me with this. I'm not at savvy with tech stuff, but when I find a recipe or something and it doesn't have an option to print a certain area, I can't understand how to use it?

  Thank you

  Andi Starbuck

  That happens to me is, I click and drag to make a rectangle of yellow selection, and as soon as I raise my finger on the mouse button, the part I've selected is captured as an image, a new tab opens and preview before printing, the image display. I can use the installation of the Page or simply print. But if I close the preview, this temporary image vanishes and I'm back on the page where I started. You see something different?
