• How to write this query in the hierarchy

  Hi gurus,

  Really need your help on this query.  Thank you very much in advance.

  SELECT
    t1.key as root_key ,
  (SELECT
        t2.unit_id AS unit_id 
        level-1 AS level ,
        t2.name,
        t2.creator
      FROM
        tab t2
        START WITH t2.unit_id       =   t1.unit_id            -----check each node as root
        CONNECT BY prior t2.unit_id = t2.parent_unit_id
  
    )
     t1.name as parent_unit_name
  FROM
    tab t1
  

  I'll write a query of the hierarchy as above, and that EACH line (node, totally more than 10200) is checked as root node to see how many sheets are accessible for her... It must be implemented in a single query.

  I know inline query should NOT return multiple rows or multiple columns, but the inline elements are necessary and can certainly be made in a correct solution.

  SELECT 8, 5, 'U8' FROM DUAL

• 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.

• How can I write a query to siolate the value after the decimal point

  This query

   
  select 
  spraddr_pidm,
  SPRADDR_CITY
   from spraddr 
  where 
   SPRADDR_NATN_CODE = 'CA'
  and SPRADDR_ATYP_CODE = 'AH'

  Returns the following output (just an example I like 1,000 records that I need to fix)
  

  140804     Toronto, Ontario
  140832     Quebec, Quebec
  140845     Halifax, NS
  140889     Mississauga, Ontario
  140902     Boucherville, Quebec
  140945     Westmount, Quebec
  136971     Montreal, Quebec
  180650     Granby, Quebec
  137007     Quispamsis, NB
  137037     Varennes, Quebec
  180746     Port Williams, NS

  As you can see that providence is inserted into the column city (SPRADDR_CITY)
  
  I want to break the column and isolated from providence, so I can insert into a custom table
  the city and providence, so I can fix the files...
  I guess the question is how do I write a query to isolate the providence...
  Thank you

  Hello

  Here's one way:

  WITH     got_comma_pos     AS
  (
       SELECT     spraddr_pidm
       ,     spraddr_city
       ,     INSTR ( spraddr_city || ','
                  , ','
                  )          AS comma_pos
       FROM     spraddr
       WHERE     spraddr_natn_code     = 'CA'
       AND     spraddr_atyp_code     = 'AH'
  )
  SELECT  spraddr_pidm
  ,     SUBSTR (spraddr_city, 1, comma_pos - 1)          AS city
  ,     LTRIM (SUBSTR (spraddr_city, 1 + comma_pos))     AS province
  FROM      got_comma_pos
  ;
  

  What do you do if there is no comma in spraddr_city? The above query assumes that the entire string is the name of the city in this case and the province with a NULL value.

  You can also use regular expressions, but this way is more effective and about as simple to code.

  It would be best to leave the desired projection.
  Probably you don't really want all columns form this query.
  However, these are your join criteria:

  t2.txnauthid = r1.txnauthid
              AND r1.rid = mk3.rid
              AND r1.regmobileno = mk1.mobileno
              AND mk1.mobileno = mk2.mobileno
              AND r1.rid = m1.rid(+)
  

  Maybe you can get rid of AND mk1.mobileno = mk2.mobileno
  with

  (SELECT mobileno
                        ,  LISTAGG(ACCOUNTNO, ',') WITHIN GROUP (ORDER BY ACCOUNTNO) AS ACCOUNTNO
                        ,  LISTAGG(ACCOUNTNO, ',') WITHIN GROUP (ORDER BY accounttype) AS ACCOUNTTYPE
                                  FROM   OMNIACCOUNT
                                         GROUP  BY mobileno)
  

  After the combination seems to be suspicious:

  AND r1.rid = mk3.rid
  AND r1.rid = m1.rid(+)
  

  The first limit the result on all lines with the same id in
  OMNIACCOUNT and UPGRADATION
  so, o see no gain from the outer join.

  Do you really need the listagg on all OMNIACCOUNT lines.
  If this isn't the case, it would be probably better to do the listagg in the final projection.

  Maybe one way could be to start with OMNIACCOUNT and join outer UPGRADATION to it.
  You can do the listagg at the end.

  Maybe something like

  select
  *
  from
  OMNIACCOUNT m1
  left outer join
  (Select
   projection goes here
  from
  log t2 join UPGRADATION r1
  on
  r1.txnauthid = t2.txnauthid

  Here's my query:
  
  SELECT c.deduction_code as deduction_code,
  d.emp_code as emp_code,
  Sum (d.employee_amt) as the amount
  Deduction_amount d, deduction_codes c
  WHERE d.year = p_year

  AND d.deduction_code = c.deduction_code
  C.deduction_code GROUP, d.emp_code

  I have a few problems:
  If the user is going to happen in the YEAR and the quarter, how do I change my query? Lets say that she entered the YEAR = 2009 and QTR = Q1, whats going to happen to my request? BTW, in the table of calendar for each year there are 26 pay periods. I can use the check_date field to determine if the pay period belongs to which quarter. I don't know how to do.
  
  Thanks in advance!

  So maybe you'd then

  ORDER BY DECODE(flag,'D',9,1) ASC...

  to get the Ds at the end of the list.

  or

  ORDER BY CASE WHAT flag = has ' (your other filters) AND then 9 or 1 end CSA,...

• How to write this query?

  Hi people,

  I need to get a query in which a set of records, I get ONLY those which previous registry has a field with a value to this topic. Other values, the field can contain are not necessary.

  I know that sounds easy but... I can't get it.

  So, for Oracle 10 g 2... Here's my query:

  SELECT a.person_id, a.person_status, a.message_id, a.order_id

  OF t_HR one

  WHERE a.person_status = "rejected".

  AND a.id >

  (SELECT max (b.id)

  OF t_HR b

  WHERE b.person_id = a.person_id

  and b.order_id = a.order_id

  AND b.person_status! "revised =".

  B.ID AND < a.id)

  ORDER BY desc a.id

  Let me explain:

  1 - HR table is a table of people. These people has serveral STATUS.

  2 - ID is a sequential (each www.voyages-sncf.com has a different identification number).

  3 - the application must get THAT all people "rejected".

  4. - However, (subquery) I need ONLY those that previous register (the second register) holds a status of "OK". If the person holds a "revised" status he's not, he should be the next register (the third)

  5.-L' ORDER ID DESC, so is the first register must have a STATUS = "rejected" and the second a 'OK '.  IF the second register = "revised", then the third register must be 'OK '. And I need this query.

  HOW DO?

  My problem: the subquery gives you previous register of the same guy, but... it does not give you the value of the State, I need, which is 'OK '.

  I tried to add to the subquery...

  SELECT max (b.id)

  OF mod_human_resource b

  WHERE b.person_id = a.person_id

  and b.order_id = a.order_id

  AND b.person_status = 'OK '.

  AND b.id < a.id

  ... but if I have 5 records of that person, the first is "rejected", the second is "accepted", the third is 'new' and the fourth is 'OK'... the subquery gives you the 4th register and which is not correct for me, it must be only the second one (prior to the first State registry).

  I need to be a query, because I need to use it on a MERGER for a DWH.

  If there is another way (function, or even a procedure) to make the MERGER rather than with a request, which would be ok too. I am poor DWH knowledge.

  Thanks in advance.

  Hello

  So, you need to know if a line is the 'first' line, and you should also know what is the 'next' status, (even the 'first' and 'next' are already defined).  This sounds like a job for analytical functions.  ROW_NUMBER can tell you if a line is first or not, and LEAD can tell you what a value on the next row.

  Since you post CREATE TABLE and INSERT statements for your own table, I'll use the table scott.emp to illustrate.

  Consider these data from scott.emp:

  SELECT DeptNo

  ename

  work

  FROM scott.emp

  ORDER BY deptno

  ename DESC

  ;

  Output:

  DEPTNO ENAME JOB

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

  10 MILLER CLERK

  PRESIDENT OF KING 10

  MANAGER 10 CLARK

  20 SMITH CLERK

  ANALYST SCOTT 20

  20 JONES MANAGER

  20 FORD ANALYST

  20 ADAMS CLERK

  30 WARD SALESMAN

  SELLER OF 30 TURNER

  30 MARTIN SALESMAN

  30 JAMES CLERK

  MANAGER BLAKE 30

  30 ALLEN SALESMAN

  Now, let's say we want only who know the departments where the forefront (in order descending ename) a job = 'CLERK', and the following line (also in descending by ename order) = "ANALYST" job, and we want to know the ename of the first row.  In other words, the correct output is:

  DEPTNO ENAME

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

  20 SMITH

  Note that deptno = 10 is not included, even if the first task is to "CLERK." that was because the second job in deptno = 10 is the "PRESIDENT", not "ANALYST."

  Here's a way to get these results:

  WITH got_analytics AS

  (

  SELECT ename, deptno, job

  ROW_NUMBER () OVER (PARTITION BY deptno

  ORDER BY ename DESC

  ) AS r_num

  LEAD (employment) OVER (PARTITION BY deptno

  ORDER BY ename DESC

  ) AS next_job

  FROM scott.emp

  )

  SELECT deptno, ename

  OF got_analytics

  WHERE r_num = 1

  AND job = 'CLERK '.

  AND next_job = 'ANALYST '.

  ;

  I hope that answers your question.

  If this isn't the case, then, as Dan (and the FAQ forum) said, post CREATE TABLE and INSERT statements for some sample data and the exact results you want from these data.

  Post your query, based on the one I have posted more top and ponit out where he gets results.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• How to write the query option in expdp

  Hi Please someone help me how to write the query option in expdp... .in expdp using the query option...
  
  where AM columnname between 5 May 12 02:57:00.000' and ' 02:59:59.999 6 May 12: ';
  
  
  Please do what is necessary...

  Pavan Kumar says:
  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.
