• query using the JOIN

  Hello
  
  
  my appearance of the table structure:
  
  Column names:
  
  Road
  BU
  sub_bu
  report_order
  sub_bu_order
  q1py
  
  My query is:
  
  Select road, bu, Sub_bu, report_order, sub_bu_order, q1py, case
  When sub_bu = 'ISS' then (select q1py from STG where 'a.sub_bu =' ESS and a.rhead = b.rhead)
  When sub_bu = "TS" then (select q1py from STG where 'a.sub_bu =' Services and a.rhead = b.rhead)
  When sub_bu = "SW" then (select q1py from STG where a.sub_bu = 'SW' and a.rhead = b.rhead)
  otherwise NULL end as q1py_bu,
  case
  When sub_bu = 'ISS' then (select q1py from STG where a.sub_bu = 'TSG' and a.rhead = b.rhead)
  When sub_bu as 'R & D' and road in ('Region owned opex', '% of income', "opex Région", "Région opex %") then
  (select q1py from STG where a.sub_bu like 'STG' and a.rhead = b.rhead)
  ANY other purpose like STG q1py_tot b where report_order = 1
  
  Result:
  
  Bu road report_order sub_bu_order q1py q1py_bu q1py_tot sub_bu
  order ESS ISS 1162 1 1 1778,4 2953.9
  
  Here I use the sub query to produce the result. I need to give the same result by using JOINS.
  
  If someone help me, by using JOINS instead of QUERY SUB and produce the same result
  
  
  
  Thanks in advance

  Maybe you can use SQL as below. (B-)

  select Rhead,bu,Sub_bu,report_order,sub_bu_order,q1py,
  case
  when sub_bu='ISS'
  then max(case when sub_bu='ESS' then q1py end)
  over(partition by rhead)
  when sub_bu='TS'
  then max(case when sub_bu='Services' then q1py end)
  over(partition by rhead)
  when sub_bu='SW'
  then max(case when sub_bu='SW' then q1py end)
  over(partition by rhead)
  end as q1py_bu
  from tsg
   where report_order=1;
  

• Internal XML to the query with join

  I have a CF page that reads an XML file in a query using < cffile > XMLParse and QueryAddrow.

  I then do a QoQ on the result and voila! I have my page.  I hide the query for 8 hours and the XML file is only reread this cache expires.  It works well.

  My problem now is that the file contains data from three tables of database instead of one, so I need to make an inner join on the tables.  But I can't do a t/t with an inner join.

  Does anyone know a way for me to do this?

  Oh, didn't know that.  How about interweaving of QofQ?  Join Query1 and Query2 requests in a new query, then join for 3 statement?

  Employee no. 100 has no manager_id, so you need an outer join:

  select first_name|| ' '||last_name Name,
  Manager,Department from employees e,
  (select first_name||' '||last_name Manager,employee_id,first_name first from employees) m ,
  (select department_name Department,department_id from departments) d where
  e.manager_id=m.employee_id (+)
  and e.department_id=d.department_id (+)
  start with e.employee_id=100 connect by e.manager_id=prior e.employee_id;
  

  Hope this helps,

• XPath query using DONKEY with AIR3.9 for iOS app

  We build an app for iOS using AIR 3.9 where we load and parse the xml document so that we can read the path of images and download stuff on iOS device. To resolve this issue, we found a solution using XCode via DONKEY where query using XPath such as 'PerformXPathQuery', 'PerformXMLXPathQuery', 'xmlReadMemory"etc.. The code runs and when build Simulator itself on mac computer. But when we're packing DONKEY with AIR 3.9, it gives the error that says that: -.

• Query using progressive relaxation take more time for execution

  HI gurus,
  
  I'm creating a query using the context and the progressive relaxation index
  
  I had started using progressive relaxation after obtaining the forum entries {: identifier of the thread = 2333942}. With the help of progressive relaxation takes more than 7 seconds for each request. Is there a way we can improve the query performance?

  Progressive relaxation works best when you select only a limited number of lines. If you retrieve ALL the rows that satisfy the query, then every step of easing should run without worrying.

  If you collect - say - the first 10 results, then if the first step in the relaxation gives 10 results so there is no need to execute the next step (actually, due to the internal buffering, which won't be exactly true but he is theoretically correct).

  The easiest way to proceed is to reformulate the query in the form

  SELECT * FROM)
  (Score select (1) SCORE, t.* FROM test_sh4 t WHERE CONTAINS (Text3, '))
  
  
  ...
  
  
  (1) > 0 ORDER BY score (1) DESC
  )
  WHERE ROWNUM<=>

  You have discovered that wildcards don't work too well, unless you use SUBSTRING_INDEX. I encourage you to avoid completely if possible, or push down much lower in the progressive relaxation. Usually, GIFT % is a useful term (matches GIFTS, GIFTED, etc.), DON % is generally more effective.

  There are a lot of steps in your progressive relaxation. It you want to reduce the number of steps, you can change:

  ((GIFT and percent of the GRID and STAPLES % and CARD %)) in Text1
  ((GIFT and percent of the GRID and STAPLES % and CARD %)) in Text2

  TO

  ((CADEAU % et % de la GRILLE et AGRAFES % et CARTE %) * 2) within Text1 ACCUM ((GIFT and percent of the GRID and STAPLES % and CARD %)) in Text2

  I don't know if it would have performance benefits - but it is worth trying to see.

  You cannot use the SQL commands that did not exist in the 8.0 database.

  Oracle Forms (and reports) has a full PL/SQL engine and (only) the SQL parser.

  However, form (and reports) PL/SQL engine / SQL parser is at a level that was in the Oracle 8.0 database.

• Query with join optimization research and details of the extra column

  I have the following SQL used for a report that comes out some stats (with some research of names). There is a good chance it is probably possible to optimize with better SQL, but I also hope to add an additional column, which I'm not sure.

  I want the extra column at one percent, which is total % of the lines of the value of the units, for the combination of category/group.

  Oracle SQL is v11.2.0

  Here's the SQL code, as it is currently:

  select a.date_adjusted, 
         a.task_name,
         sum(case when a.units_adjusted is not null then a.units_adjusted else a.units_original end) Units, 
         b.group_name, 
         b.category_name
  from   actuals_intake a
  left join
  -- lookups to obtain group and category names from their ID's in the groupings table
         (select c.task_id, 
                 d.group_name, 
                 e.category_name, 
                 c.business_unit_id
          from   task_groupings c,
                 task_groups d,
                 task_categories e
          where  c.group_id = d.id
          and    c.business_unit_id = d.business_unit_id
          and    c.category_id = e.id
          and    c.business_unit_id = e.business_unit_id
  ) b
  on    a.task_id = b.task_id
  and   a.business_unit_id = b.business_unit_id
  where a.business_unit_id = :P10_SELECT_BUSINESS_UNIT
  and   a.date_adjusted between to_date(:P10_DATE_START, 'dd-mon-yyyy') and to_date(:P10_DATE_END, 'dd-mon-yyyy')
  group by a.date_adjusted, a.task_name, b.group_name, b.category_name
  order by a.date_adjusted, b.category_name, b.group_name
   

  This will set up the tables and data:

  15/03/2014	Task 6	40	Group three	Category B	73
  15/03/2014	Task 4	400	Group two	Category B	100

  Hope all that makes sense... Anyone able to help me do this effectively?

  Hello

  Use the analytical RATIO_TO_REPORT function to calculate the % of units column.

  If you're serious about performance, please refer to the Forum:

  Re: 3. how to improve the performance of my query? / My query is slow.

  Do you really need an outer join?  Inner joins are faster.  With the given sample data, they produce the same results.

  COALESCE may be a little faster than the CASE.

  Try this:

  WITH got_units AS

  (

  SELECT a.date_adjusted,

  a.Task_Name,

  sum of units (COALESCE (a.units_adjusted, a.units_original));

  b.group_name,

  b.category_name

  of actuals_intake one

  the left join - or just JOINED

  -research for the group names and category of their ID in the table of groupings

  (select c.task_id,

  d.group_name,

  e.category_name,

  c.business_unit_id

  of task_groupings c,.

  task_groups d,

  e task_categories

  where d.id = c.group_id

  and c.business_unit_id = d.business_unit_id

  and c.category_id = e.id

  and c.business_unit_id = e.business_unit_id

  Thanks for the display of the data of the sample; It is very useful.  Don't try to insert strings, for example, March 15, 2014", in DATE columns.  TO_DATE allows to convert strings to DATEs.

• How to write a query to join and right join

  Hello

  With the help of 10 gr 2:

  I have a scenario where generate us a report by joining a few tables.

  same goes for ex:

  Select col1, col2, col5, col10 col22...

  from tableA, tableB.

  where tableA.col1 = tableB.col1 etc.

  I have a requirement where choose a flag in the front-end server must be a right join.  so, if the flag is N, I need to return the data returned by the join; but, if the flag is there I need to make a right join and returns all the data corresponding to table A and table B, as well as the data in table B.

  (I did mention only two tables, as they are, they main engines, there are very many other tables joined in this request)

  It is possible to write a query, so that the two scenarios can be addressed based on the flag?

  Thanks in advance

  No, it does not matter.

  The optimizer evaluates what condition will be faster and/or more selective (that is, will eliminate the most lines) and make the first condition.

  If the optimzer cannot decide on what terms will be faster or more selective, it can arbitrarily don't close at the end of the WHERE clause first, but, even if you already knew for sure, this is exactly the kind of thing that is likely to change from one version to the other, or platform to another.

  The optimizer (in recent versions, at least) is very good.  If the optimizer can not say what conditions should apply first, then, chances are, there is really no significant difference, so it would be not serious of which one was made first.

  If you read something that indicates the order is important, it is very outdated.  Long ago (version 6), there was no cost-based optimizer and the order of the conditions in the WHERE clause was important.  The cost-based optimizer was introduced in Oracle 7 (1992) and has been greatly improved by Oracle 8.1 (1998).  Also later Oracle 10, the older optimizer ("regulated") was available for those who really want to continue to use it.

• 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.
  
  Kindly help me on this.
  
  Thank you

• Query using link help?

  I'm quite new in the world of SQL and I'm having a problem with an application using binding. I use SQL Developer (3.1.07).
  If I run the query with no binding, everything works fine. Normal occasions I have run this query on the day I want my totals and I get my desired results:
  
  HIS SELECTION. CRAFTS, nvl (SUM (SA. (LABORHRS), 0) ' loaded hours. "
  SOL_SCHEDULEBASELINEWOASGMNT SA
  LEFT JOIN SOL_SCHEDULEBASELINE ON SB SB. BASELINEID = SA. BASELINEID
  WHERE SB. DATECODE = "DAILY".
  AND TO_CHAR (SB. FROMDATE, "MON-DD-YYYY") = TO_CHAR (SYSDATE, ' DD-MON-YYYY "")
  AND TO_CHAR (SB. TODATE, 'DD-MON-YYYY') = TO_CHAR (SYSDATE, ' DD-MON-YYYY "")
  AND TO_CHAR (SA. SCHEDULEDATE, "MON-DD-YYYY") = TO_CHAR (SYSDATE, ' DD-MON-YYYY "")
  Sa.craft group
  sa.craft asc order
  
  BOATS loaded hours
  ---------- -------------------
  CONTROL.     24
  12 MM
  MT 6
  
  
  BUT * I want to enter my own date rather than use sysdate. This will be for when I get bored of running this for a day, wonder for the values of an earlier date, etc...
  The value will always be the same for all three date fields (SB. FROMDATE, SB. TO DATE, SA. SCHEDULEDATE)
  I modified the request here and the query still works very well at this stage: (I use April 1, 2012 to my link...)
  
  HIS SELECTION. CRAFTS, nvl (SUM (SA. (LABORHRS), 0) ' loaded hours. "
  SOL_SCHEDULEBASELINEWOASGMNT SA
  LEFT JOIN SOL_SCHEDULEBASELINE ON SB SB. BASELINEID = SA. BASELINEID
  WHERE SB. DATECODE = "DAILY".
  AND SB. FROMDATE =: DDMONYYYY
  AND SB. TODATE =: DDMONYYYY
  AND TO_CHAR (SA. SCHEDULEDATE, "MON-DD-YYYY") = TO_CHAR (SYSDATE, ' DD-MON-YYYY "")
  Sa.craft group
  sa.craft asc order
  
  BOATS loaded hours
  ---------- -------------------
  CONTROL.     24
  12 MM
  MT 6
  
  Now I change my request to what follows, I get a different result:
  
  HIS SELECTION. CRAFTS, nvl (SUM (SA. (LABORHRS), 0) ' loaded hours. "
  SOL_SCHEDULEBASELINEWOASGMNT SA
  LEFT JOIN SOL_SCHEDULEBASELINE ON SB SB. BASELINEID = SA. BASELINEID
  WHERE SB. DATECODE = "DAILY".
  AND SB. FROMDATE =: DDMONYYYY
  AND SB. TODATE =: DDMONYYYY
  AND SA. SCHEDULEDATE =: DDMONYYYY
  Sa.craft group
  sa.craft asc order
  
  BOATS loaded hours
  ----------- ------------------
  CONTROL.     10
  
  All columns have a Date data_type.
  As soon as I change SA. SCHEDULEDATE of
  
  AND TO_CHAR (SA. SCHEDULEDATE, "MON-DD-YYYY") = TO_CHAR (SYSDATE, ' DD-MON-YYYY "")
  
  TO
  
  PAM SCHEDULEDATE =: DDMMYYYY
  
  He keeps the results I need back.
  
  Why is this? Does anyone have an idea of what's going on here? Any help would be GREATLY appreciated!
  Thank you

  Hello

  Welcome to the forum!

  I'm not very familiar with SQL Developer. Should bind variables DATE? Other Oracle products; in them, you must use VARCHAR2 variables, like this (which works in SQL * more):

  VARIABLE  ddmonyyyy     VARCHAR2 (11)
  EXEC     :ddmonyyyy := '01-Apr-2012';
  
  SELECT        SA.CRAFT
  ,        NVL (SUM (SA.LABORHRS), 0)     as "Loaded Hours"
  FROM             SOL_SCHEDULEBASELINEWOASGMNT        SA
  LEFT JOIN      SOL_SCHEDULEBASELINE              SB   ON   SB.BASELINEID = SA.BASELINEID
  WHERE     SB.DATECODE                       = 'DAILY'
  AND        TO_CHAR (SB.FROMDATE,     'DD-MON-YYYY') = :ddmonyyyy
  AND        TO_CHAR (SB.TODATE,       'DD-MON-YYYY') = :ddmonyyyy
  AND        TO_CHAR (SA.SCHEDULEDATE, 'DD-MON-YYYY') = :ddmonyyyy
  GROUP BY  sa.craft
  ORDER BY  sa.craft     ASC
  ;
  

  It's very similar to your original query, where you have used TO_CHAR on all your DATE columns.

  Moreover, it would be more effective liaison conve\rt variable of a DATE, rather than convert the DATE on each row of a VARCHAR2. In other words, replace the comparisons as

  AND        TO_CHAR (SA.SCHEDULEDATE, 'DD-MON-YYYY') = :ddmonyyyy
  

  with

  AND        SA.SCHEDULEDATE >= TO_DATE (:ddmonyyyy, 'DD-MON-YYYY')
  AND        SA.SCHEDULEDATE <  TO_DATE (:ddmonyyyy, 'DD-MON-YYYY') + 1
  

  If is a coding more. It is up to you to decide if the efficiency improvement is worth.

• Alias a field name in a query to join

  I have a database with spaces in domain names (not my fault).

  I'm having a problem with the query because among the fields on that I join has a space in its name. See the text in bold.

  SELECT *.

  Of employee_passwords

  INNER JOIN employee_general_info

  ON employee_passwords. Employee_id = employees. [Ref used]

  WHERE username = ' #username # ' AND password = ' #password #

  So, I get this error message

  Run database query error.
  [Macromedia] [SQLServer JDBC Driver] [SQL Server] Invalid object name ' employees. ID of the employee.

  Is there a way to alias employees. [Field employee ID]?

  The error is probably from a SELECT *-try the list of all the fields individually, including the [employee ID] field.  You can give it a new name to appear in the results of the query by folding, it:

  SELECT [employee Ref] AS EmployeeID

  but within the query itself, you must use the syntax [employee Ref].

• problem with a query, inner join

  Hello;

  I am trying innerjoin these 2 tables in my request for a page that will allow you to add / modify records. Right now, it tells me that I have a lag of data. I do not see where I was wrong. Can someone help me?

  
  This is my code:

  < name cfparam = "url. CategoryID"type ="integer"default ="0">
  < name cfparam = 'subID' type = 'integer' default = '#url. CategoryID #">"
  < name cfparam = "subName" default = "" >
  < name cfparam = "CategoryID" default = "" >
  < name cfparam = "Name" default = "" >

  < cfif url. CategoryID GT 0 >
  < name cfquery = "categRec" dataSource = "#APPLICATION.dataSource #" >
  SELECT merchSubCat.subName, merchSubCat.subID, categories. CategoryID, Categories.Name
  OF merchSubCat
  JOIN INTERNAL categories
  ON merchSubCat.CategoryID = categories. CategoryID
  WHERE merchSubCat.subID = < cfqueryparam value = '#url. "CategoryID #" cfsqltype = "cf_sql_integer" >
  < / cfquery >

  <!-if the records were found, store the values->
  < cfif categRec.RecordCount EQ 1 >
  < cfset CategoryID = categRec.subID >
  < cfset subName = categRec.subName >
  < cfset CategoryID = categRec.CategoryID >
  < cfset Name = categRec.Name >
  < / cfif >
  < / cfif >

  It's my mistake:

  Run database query error.

  [Macromedia] [SequeLink JDBC Driver] [ODBC Socket] [Microsoft] [ODBC Microsoft Access driver] Type in an expression mismatch.

  The error occurred in C:\Websites\187914kg3\admin\cms\merchant\merchSub-edit.cfm: line 16

  
  

  14 : INNER JOIN Categories
  15 :     ON merchSubCat.CategoryID = Categories.CategoryID
  16 : WHERE merchSubCat.subID = <cfqueryparam value="#url.CategoryID#" cfsqltype="cf_sql_integer">
  17 : </cfquery>
  18 : 
  

  I don't see what I did wrong, another pair of eyes can see where I missed something?

  Thank you

  I think that you just want to use the URL. CategoryID parameter:

  
  --Choose a category--
