  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.

• Rewrite the query with joins, and group by

  Hello
  
  It's an interview question.
  
  Table names: bookshelf_checkout
  virtual library
  
  And the join condition between these two tables is title
  
  We need to rewrite under request without using the join condition and group by clause?
  
  

  SELECT b.title,max(bc.returned_date - bc.checkout_date) "Most Days Out"
             FROM bookshelf_checkout bc,bookshelf b
             WHERE bc.title(+)=b.title
             GROUP BY b.title;

  When I was in College, I read most of SELECT statements can be replaced by operations base SQL (DEFINE the OPERATORS). Now, I am rewriting the query with SET operators, but not able to get the exact result.

  QUERY = (columnname scott.test: "where between 5 May 12 02:57:00.000 h ' and ' 6 May 12 AM 02:59:59.999'")

  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.

  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)

  Thank you

  DV63

  Hi DV63,

  Welcome to the Forums EITHER!

  If you downloaded an evaluation version of LabVIEW your 30 day trial must begin immediately after being invited to enter a serial number. You can choose not to enter a serial number and this will begin your trial period. I recommend that you install OR-DAQmx device drivers; It is a software that allows you to communicate with the hardware from National Instruments DAQ. However, this facility will be particularly useful because it allows you to simulate an Instrument with the measurement and Automation Explorer (MAX); This means that you can immediately start the signals in LabVIEW.

  Most of the games do not work in safe mode, because safe mode loads only the system drivers and not the games so it is really moot to wonder if he would run faster.
