• Cannot return number of orders by the hour in the request please help

  Here's the query I run currently. It allows you to select the Date and time on a form and returns a total number of commands between the Date and the selected hours. What I need to break further down, at the time, the number of orders. So it should take the 05:00 06/08/2012-06/08/2012 11:00 show me the number of orders at the time. Where currently it totals orders for the chosen duration
  
  This query currently works but does not divide it by time unless I select the 05:00 06/08/2012-06/08/2012 06:00 and then repeat for each hour. Which is very time consuming.
  
  Any help would be amazing as I have been at it for weeks.

• A query containing a subquery and Group By all-in-one

  Hi people,
  Any interesting fact but nerve racking situation I have here. I have a question that I have to do counts and amounts and I also need to have a Sub inside query. When I run my application, I get an error like this:
  
  Error in the command line column: 4:36

           substr(acc.account_num,1,12) account_number,
         ( select acc2.account_desc from student_account  acc2
           where  acc2.account_num = acc.account_num

  If I replace it with the acc.account_num (subquery) with a number that is in the database, then my request works well.

  Hello

  We don't know what you want. It would really help if you posted some examples of data (CREATE TABLE and INSERT statements) and the results desired from these data.

  Are you sure that the scalar subquery will return ever more than one line? If so, you can wrap in a MIN or MAX aggregate function, as I've suggested before:

   select distinct to_char(c.start_date,'YYYY') start_date,
           substr(acc.account_num,1,12) account_number,
     MIN ( ( select acc2.account_desc from student_account  acc2     -- Changed
           where  acc2.account_num = acc.account_num
           and    acc2.account_type = 'A'
         ) ),                                   -- Changed
         COUNT(distinct(s.student_id))
  from student s,
         student_account acc,
         course   c
  where s.course_id = c.course_id
  and     s.account_num = acc.account_num
  and    to_char(c.start_date, 'YYYY/MM/DD') between '2004/01/01' and '2009/12/31'
  group by to_char(c.start_date,'YYYY'), substr(acc.acct_acc_num,1,12)
  order by 1;
  

  It seems that you could also simplify the query and make more fast, eliminating the scalar subquery. The table there is already part of the main query, you can do something like this:

  SELECT    TO_CHAR (c.start_date, 'YYYY')     AS start_date
  ,         SUBSTR (acc.account_num, 1, 12)      AS account_number
  ,       MIN ( CASE
                      WHEN  acc.account_type = 'A'
                THEN  account_desc
                  END
             )                         AS a_desc
  ,         COUNT (DISTINCT s.student_id)          AS student_id_cnt
  FROM       student            s
  ,       student_account     acc
  ,       course          c
  WHERE       s.course_id          = c.course_id
  AND       s.account_num          = acc.account_num
  AND       c.start_date          BETWEEN DATE '2004-01-01'
                        AND     DATE '2009-12-31'
  GROUP BY  TO_CHAR (c.start_date, 'YYYY')
  ,            SUBSTR (acc.acct_acc_num, 1, 12)
  ORDER BY  start_date;
  

  I guess that course.start_date is a DATE. Instead of converting each start_date to string (so you can see if it is in the right range), it is more efficient and less prone to error, compared to other DATEs, as shown above.

  It is very strange that you

  substr(acc.account_num,1,12)
  

  in the select clause, but

  substr(acc.acct_acc_num,1,12)
  

  in the GROUP BY clause. Did you mean having the same column in both places?

  Yet once, without seeing some examples of data (CREATE TABLE and INSERT statements) and the results desired from this data, I can't do much.

• Subquery in GROUP BY CLAUSE

  Is it possible to place a subquery in the GROUP BY CLAUSE? If this is the case, can anyone show me an example? Thank you

  Hello

  This is a GROUP BY clause that uses an IN subquery:

  SELECT    COUNT (*)     AS cnt
  FROM       scott.emp
  GROUP BY  CASE
            WHEN deptno  IN (
                           SELECT     deptno
                           FROM     scott.dept
                           WHERE     loc     = 'NEW YORK'
                      )
            THEN  1
            ELSE  2
         END
  ;
  

  I've never seen a need for it (and I was at a state fair, a rodeo and a picnic!)

  Interestingly, if I copy the expression in the GROUP BY clause from the SELECT clause:

  SELECT    COUNT (*)     AS cnt
  ,       CASE
            WHEN deptno  IN (
                           SELECT     deptno
                           FROM     scott.dept
                           WHERE     loc     = 'NEW YORK'
                      )
            THEN  1
            ELSE  2
         END          AS new_york
  FROM       scott.emp
  GROUP BY  CASE
            WHEN deptno  IN (
                           SELECT     deptno
                           FROM     scott.dept
                           WHERE     loc     = 'NEW YORK'
                      )
            THEN  1
            ELSE  2
         END
  ;
  

  I get this error:

  ...             WHEN deptno  IN (
                       *
  ERROR at line 3:
  ORA-00979: not a GROUP BY expression
  

  Despite what this book says you can use a subquery-IN like this in an ORDER BY clause:

  SELECT       deptno
  FROM       scott.emp
  ORDER BY  CASE
            WHEN deptno  IN (
                           SELECT     deptno
                           FROM     scott.dept
                           WHERE     loc     = 'DALLAS'
                      )
            THEN  1
            ELSE  2
         END
  ;
  

  (New York is Department 10, the first anyway, is not as clear to use the same exact example.)

• Grouping of SQL with a subquery

  Hi all
  
  I had to get an output by combining the same field by using 2 different condition. I tried to use the subquery, but the output is not getting properly completed.
  
  example of the query will be something like:
  
  Select count (*), _ (select count (*) from TableX where = 1 condition) from TableX Grouper by FieldA.
  
  The output is considered the first condition + (Count + have 2 folders and subquery (.. .or condition = 1) with also 2 records.)
  
  But the real result for the subquery if I run the query separately is only 1 card. The query has filled the second row with the same performance as a result of the first condition with 2 records to return. Anyway I put a condition to bring together both the condition?
  
  Thank you.

  Something like that?

  select sum(case when  then 1 else 0 end ) first_count, sum(1) total_count from TableX group by FieldA;

• Subquery in the select clause and not "a group by expression" error.

  Hi all
  I hope someone out there can help me out with this one. I have a sql query that performs a subquery in the select case combined with an aggregate function and gives me a "not a group by expression.
  
  I created a simplified example

   SELECT COUNT(*)                     ,
    ai.invoice_num invoice_number      ,
    ai.description invoice_description ,
    (SELECT poh.po_header_id
         FROM po_headers poh ,
        po_distributions pod
        WHERE pod.po_distribution_id = aid.po_distribution_id
      AND pod.po_header_id           = poh.po_header_id
      ) po_number
       FROM ap_invoice_distributions aid ,
      ap_invoices ai
      WHERE ai.invoice_id = 1476932
    AND aid.project_id    = 8608   
    AND aid.task_id       = 462202  
    AND ai.invoice_id     = aid.invoice_id
   GROUP BY ai.invoice_num,
                  ai.description;

  I'm sure he expected me to add the po_number to the group by clause, but this does not work and gives the error "invalid identifier".
  
  Can someone suggest a way for a new concert the query so that I can add po_number to my education by clause.
  
  Kris

  You should try either:

  SELECT COUNT (*),
  AI.invoice_num invoice_number,
  have. Description invoice_description,
  (SELECT poh.po_header_id
  OF po_headers poh,.
  pod po_distributions
  WHERE pod.po_distribution_id = aid.po_distribution_id
  AND pod.po_header_id = poh.po_header_id
  ) po_number
  HELP ap_invoice_distributions.

  AND aid.project_id = 8608
  AND aid.task_id = 462202
  AND ai.invoice_id = aid.invoice_id
  Ai.invoice_num GROUP,
  have. Description, aid.po_distribution_id;

  or

  SELECT COUNT (*),
  AI.invoice_num invoice_number,
  have. Description invoice_description,
  MAX ((SELECT poh.po_header_id
  OF po_headers poh,.
  pod po_distributions
  WHERE pod.po_distribution_id = aid.po_distribution_id

  Hello

  I see: XYZ123 is linked only to a part_type_id, 7777, so you do not want any output to XYZ123.

  Similarly, XYZ456 is only linked to a part_type_id, 8888, so you do not want XYZ456.

  One thing you can do is to start with the query in response to #4 above.  The results of this query, you can count part_type_ids h: different lots, each part_num is bound to and then only display the part_nums who have more than 1 part_type_id.  For example:

  WITH got_aggregates AS

  (

  SELECT THE CHECK BOX

  WHEN you GROUP (part_type_id) = 0

  THEN TO_CHAR (part_num)

  ELSE '-'

  END                               AS txt

  part_type_id, part_type_txt

  CASE

  WHEN you GROUP (part_type_id) = 0

  THEN COUNT (part_num)

  END                               AS cnt

  part_num,

  COUNT (DISTINCT part_type_id)

  COURSES (PARTITION BY part_num) AS part_type_id_cnt

  TAB

  ID WHERE = 1

  GROUP BY part_num, ROLLUP (part_type_id, part_type_txt))

  )

  SELECT txt, part_type_id, part_type_txt, cnt

  OF got_aggregates

  WHERE part_type_id_cnt > 1

  ORDER BY part_num, part_type_id

  ;

  Note that the subquery got_aggregates is almost identical to the response query #4.  The only differences are that the subquery is not an ORDERBY clause (ORDER BY is almost always useless to subqueries) and includes two additional columns, which will be needed in the WHERE and ORDER BY the main query clauses.

  Hello

  Here's another way.  It's like the solution in response #1, but it does not use a subquery:

  SELECT t.col1

  CASE

  WHEN COUNT (DISTINCT t2.col2) > 1

  THEN "Multiple."

  For ANOTHER MIN (t2.col2)

  END AS rnd_col

  T

  LEFT OUTER JOIN t2 ON t2.col1 = t.col1

  GROUP OF t.col1, t.col2, t.col3

  ORDER BY t.col1

  ;

  This assumes that in table t (col1, col2, col3) combination is unique.  If theat is not the case, change the GROUP BY clause, but you need to ensure that all lines of t becomes a separate group.

  So, in that the above example, I would expect only record 1 to return as his last entry in the table def_id = 11.

  That's what I have, but obviously does not work as it throws an error on the max function, can someone please help with it?

  where exists (
    select * from Table_A a
              where a.record_id in (b.record_id) and max(a.def_id) in (
              select ad.def_id from Table_A_DEF ad where ad.def_name in ('definitionA', 'definitionN')
    )
  
  

  Here's a way (using either exist or subquery in the list)...

  with Table_A (record_id, def_id, date_A) as)

  Select 1, 11, date ' 2015-06-07 the Union double all the

  Select day 1, 34, '' 2015-06-01 Union double all the

  Select 1, 55, date ' 2015 - 05 / 05' Union double all the

  Select option 2, 34, day ' 2015-06-04 Union double all the

  Select option 2, 11, date ' double' 2015-05-08

  )

  Table_A_DEF (def_id, def_name) as)

  Select 11, 'examine' from dual union all

  Select 34, 'definitionF' from dual union all

  Select 50, 'DEFINITIONH' from dual union all

  Select 55, "definitionN' from dual

  )

  Table_B (record_id, record_name) as)

  Select 1, "record1" dual union all

  Select 2, 'record2"dual union all

  Select 3, 'registration' record3 of the double

  )

  Select record_id, record_name

  of table_B

  When there is)

  Select null

  from table_A

  Join table_A_DEF

  using (def_id)

  where table_A.record_id = table_B.record_id

  Record_id group

  having max (def_name) to keep (last dense_rank command by date_A)

  in ("examine", "definitionN")

  )

  ;

  -or-

  Select record_id, record_name

  of table_B

  where record_id in)

  Select record_id

  from table_A

  using (def_id)

• create id by group

  Hello

  I have a requirement that seems simple, but I'm unable to create the sql for it.

  We have a table on a database 10.2.0.4 that looks like this:

  create the table groupid_example

  (

  Identification number not null,

  VARCHAR2 (32) F1.

  F2 varchar2 (32),

  F3 varchar2 (32),

  number of GroupId,

  form sdo_geometry

  );

  And contains the records:

  insert into GROUPID_EXAMPLE (ID, F1, F2, F3, GROUPID) values (1, 'A', 'A', 'A', null);

  insert into GROUPID_EXAMPLE (ID, GROUPID, F1, F2, F3) values (2, 'A', 'A', 'A', null);

  insert into GROUPID_EXAMPLE (ID, GROUPID, F1, F2, F3) values (3, 'B', 'B', 'B', null);

  insert into GROUPID_EXAMPLE (ID, F1, F2, F3, GROUPID) values (4, 'B', 'B', 'C', null);

  insert into GROUPID_EXAMPLE (ID, F1, F2, F3, GROUPID) values (5, 'C', 'C', 'C', null);

  insert into GROUPID_EXAMPLE (ID, F1, F2, F3, GROUPID) values (6, 'C', 'C', 'C', null);

  The sdo_geometry is really irrelevant to the requirement, but it prevents the use of the merge statement.

  The condition is that all records with the same f1, f2 and f3 values must obtain the same value to the groupid. In addition, the groupid must be numbered in the order increasing by f1, f2, f3.

  The power required is:

  ID	F1	F2	F3	GROUPID
  1	A	A	A	1
  2	A	A	A	1
  3	B	B	B	2
  4	B	B	C	3
  5	C	C	C	4
  6	C	C	C	4

  I tried using row_number() like this:

  Update groupid_example g

  Set groupid = (select groupid

  from (select row_number() over (order by f1, f2, f3) groupid, f1, f2, f3)

  Group groupid_example by f1, f2, f3) s

  where g.f1 = s.f1

  and g.f2 = s.f2

  and g.f3 = s.f3);

  This works fine on a small set, but takes forever on the 1 million rows in the table.

  There must be a simpler and more elegant way to do...

  Thanks in advance!

  From a theoretical point of view, it just bothers me that a pl/sql cursor loop that updates the records online is much faster than a pure SQL.

  It is as you have already said pointing to the plan of the explain command.

  In this case no unnesting of the subquery is possible and that is why there is a hughe work performed for each line.

  You can move it with simple sql if you are using views fusion or updateble.

  None of this applies in this case, if im my opinion you have discovered the best approach for yourself.

• How to determine the number of records in a subquery

  I am fairly new to Oracle SQL, and would like to know if anyone has examples of how to perform the following operations:

  1. I would return the number of rows that exist in the following SQL statement below. This SQL will be part of a larger SQL statement and I will be passing in the EMPLID identifier in the subquery. The result must be a value showing the total number of records that correspond to the SQL below. "xyz" will be finally passing through the extension number of the employee by using a reference to the parent SQL... ie: jbe. POSITION_NBR
  2. My SQL:

  SELECT Cjbe. EMPLID OF PS_JOB cjbe
  WHERE cjbe. POSITION_NBR = "xyz".
  GROUP BY cjbe. EMPLID

  I would like to know how I can change the value of poarent to POSITION_NBR (I think I use jbe.) POSITION_NBR) total calls the EMPLID found in this subquery subquery and then return.

  Thanks for your help.

  Maybe I lack something, but isn't this just

  SELECT count (distinct empl_id) from ps_job where position_nbr =: some_position_nbr

  Hello

  I think it's one of those things that CONNECT BY is better.

  Here's a way to do it using a recursive clause (AND not CONNECT BY):

  WITH recursive_results (ancestor_id, descendant_id, value, lvl, lineage) AS

  (

  SELECT id AS ancestor_id

  id LIKE descendant_id

  value

  ,       1                     AS lvl

  , TO_CHAR (id, "9999") AS line

  T

  UNION ALL

  SELECT r.ancestor_id

  t.id AS descendant_id

  t.valeur

  r.lvl + 1 AS lvl

  r.lineage | ' /'

  || To_char (t.id, '9999') AS line

  T

  JOIN recursive_results r WE t.parent_id = r.descendant_id

  )

  SELECT LPAD (' ' ')

  , 4 * (

  SELECT MAX (lvl) - 1

  OF recursive_results

  WHERE descendant_id = m.ancestor_id

  )

  ) || ancestor_id AS indented_id

  SUM (CASE WHEN ancestor_id = descendant_id THEN value END) AS self_value

  The amount (value) AS branch_value

  OF recursive_results m

  GROUP BY ancestor_id

  ORDER BY)

  SELECT MAX (lineage) DUNGEON (DENSE_RANK LAST ORDER BY lvl)

  OF recursive_results

  WHERE descendant_id = m.ancestor_id

  )

  ;

  Output (even you have):

  You can do this via an opaque view.

  You can also do this by modeling the cumulative value as a calculation LOGIC in the group by aggregation "pinned" to a specific dimension hierarchy that reflects consolidation in the online posting.
