Ask. UNION ALL on two tables of dummy data

Similar Questions

• Please help me with the Alternative of queries to replace the UNION ALL for two queries

  Hi all

  I have the query to retrieve assets employees salary count and in so far as below:

  Select ename, emp_no, sum (sal_till_2010), sum (sal_till_2014) of

  (select emp_no, ename, salary as sal_till_2010, 0 as sal_till_2014 of employee e1

  where effective_date < = 1 January 2010 ' and not exists (select 1 from e2 employee_deletion where e2.emp_no = e1.emp_no and e2.deletion_date < = January 1, 2010 "")

  UNION ALL

  Select ename, emp_no, 0 as sal_till_2010, salary as employee e1 sal_till_2014 - here is a dummy 0 salary until 2010 for the union of all the

  where effective_date < = 1 January 2014 "and not exists (select 1 from e2 employee_deletion where e2.emp_no = e1.emp_no and e2.deletion_date < = 1 January 2014") "

  Group of emp_no, ename;

  In this query, I get the total salary until 2010 and until 2014 in the employee table, dates are dynamically passed to the procedure, and this can change.

  But assume the date above and let me know the alternative of queries to improve performance because I use Union ALL and read the same table twice in the above query.

  Advice me with request to read the table once to fetch the same data as the above query.

  Thanks in advance.

  
  

  Hello

  Thanks for the display of the data of the sample; It's very useful!

  I think OP wants something like this:

  WITH cutoff_dates AS

  (

  SELECT TO_DATE (January 1, 2010 ', ' DD/MM/YYYY') AS cutoff_date, 2010 UNDER the label OF dual UNION ALL

  SELECT TO_DATE (1 January 2014 ', "DD/MM/YYYY"), double 2014

  )

  SELECT e.emp_no, e.ename

  , NVL (SUM (CASE WHEN c.label = 2010 THEN e.salary END), 0) AS sal_till_2010

  , NVL (SUM (CASE WHEN c.label = 2014 THEN e.salary END), 0) AS sal_till_2014

  E employee

  JOIN cutoff_dates c ON e.effective_date<=>

  WHERE DOES NOT EXIST)

  SELECT 1

  Of employee_deletion ed

  WHERE ed.emp_no = e.emp_no

  AND ed.deletion_date<=>

  )

  E.emp_no GROUP, e.ename

  ORDER BY e.emp_no

  ;

  Output of your sample data:

  EMP_NO ENAME SAL_TILL_2010 SAL_TILL_2014

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

• Display data from two tables based on date criteria

  Hi all
  
  I have two tables, using these two tables and a few conditions I want to recover under result. Oracle version is (Oracle9i Enterprise Edition Release 9.2.0.8.0 - 64 bit Production)
  

  LOGON_ID        USER_ID       LOGON_TIME                 LOGON_TYPE    SUBSCRIBER_NO               CUSTOMER_ID
  
  26063548     4528890298   4/5/2010 12:03:58 AM            MSISDN       GSM04528890298              581751708

  logon_histories_r table records the information of each user who connects to the system. Subscriber Details table contains all the information corresponding to subscriber_no, only 1 row should be returned.
  I'm confused usage date condition for the table of the Subscriber, the input parameter date 04/04/2006 to 15/04/06
  
  Select lh.logon_id, lh.user_id, lh.logon_time, lh.logon_type, subs.subscriber_no, subs.customer_id
  of logon_histories_r lh, subscribed subs
  where lh.logon_time > = to_date('05-04-2010','dd-mm-yyyy')--to_date('04-04-2006','dd-mm-yyyy')
  and lh.logon_time < to_date('06-04-2010','dd-mm-yyyy')--to_date('15-01-2007','dd-mm-yyyy')
  and lh.user_id = substr (subs.subscriber_no,-10);
  
  If the date range is 04/05/2010 to 04/06/2010 then the data related to the BAN 581751708 must be the result,
  If the date range is 04/04/2006 to 15/01/2007 data related to the BAN 502499502 must be the result.
  
  Please find DDL and data relevant to these results. There are millions of records of Subscriber & logon_histories_r table, I am given appropriate providing a subscriber_id.

  Welcome to the froum!

  Thanks for posting the CREATE TABLE and INSERT! It's very nigra.

  logon_histories_r table records the information of each user who connects to the system. Subscriber Details table contains all the information corresponding to subscriber_no, only 1 row should be returned.

  Do you mean a line by the user, or a line every time that you run the report, regardless of the number of users connected during the period that interests us?
  Anyway, if there are multiple logons, how do you decide that one? Or the output of logon_histories_r columns will be a sort of composite?

  I'm confused usage date condition for the table of the Subscriber, the input parameter date 04/04/2006 to 15/04/06

  Select lh.logon_id, lh.user_id, lh.logon_time, lh.logon_type, subs.subscriber_no, subs.customer_id
  of logon_histories_r lh, subscribed subs
  where lh.logon_time > = to_date('05-04-2010','dd-mm-yyyy')--to_date('04-04-2006','dd-mm-yyyy')
  and lh.logon_time< to_date('06-04-2010','dd-mm-yyyy')="" --="">
  and lh.user_id = substr (subs.subscriber_no,-10);

  Must LH.LOGON_TIME match something in the subscruber table? If so, you need to addsome extra join pathological.
  For example, if lh.logon_time must be between d1 and d2 (where d1 and d2 are DATE columns), then:

  select      lh.logon_id
  ,     lh.user_id
  ,     lh.logon_time
  ,     lh.logon_type
  ,     subs.subscriber_no
  ,     subs.customer_id
  from      logon_histories_r      lh
  ,      subscriber           subs
  where      lh.logon_time      >= to_date ('05-04-2010','dd-mm-yyyy') -- to_date('04-04-2006','dd-mm-yyyy')
  and      lh.logon_time      <  to_date ('06-04-2010','dd-mm-yyyy') -- to_date('15-01-2007','dd-mm-yyyy')
  and      lh.user_id      = substr (subs.subscriber_no, -10)
  and     lh.logon_time     >= subs.d1     -- New condition added
  and     lh.logon_time     <= subs.d2     -- New condition added
  ;
  

  Please find DDL and data relevant to these results. There are millions of records of Subscriber & logon_histories_r table, I am given appropriate providing a subscriber_id.

  That's smart, don't not post each row of the table: looks like you posted just enough to show what the problem is.
  Try to do the same thing with the columns. Do not post every single column, just the columns that have something to do with the problem.

• Great way to add more than two tables on the data sources

  Hello world
  
  I would like to confirm everything that follows before doing so on my interface.
  
  I work with an interface that is suppoused to pass data from some of the oracle tables in a DB X to an oracle table in a DB Y.
  
  The target data store got a foreign key, that is why I have to download two tables on the area of thesources. Is this right? Should I tell the two tables sort? I mean those procurement.
  
  I know this may seem a stupid question, but I like teo do things and to understand what I do in the future I can improve! If you can recommend me some additional reading on this I would really aopreciate your help and your advice.
  
  Do not hesitate to contact me if additional information is required.
  
  Best regards.
  
  Jaison

  If the form of files your multiple source tables are a unique entry in the table target, then they will certainly be linked. You can drag columns from a source model to another model of source to generate a join in the designer criteria.

• Immagerie two tables without a CARPENTER

  Hello
  I had a little problem. I want to combine the two tables. But I don't need a Carpenter, cause that would give me wrong combined values.
  I have a table working_hours which has the actual hours of work of employees. And a table times_absent that the absent employee time.
  The two tables have the date and hours actual work and absent in addition to other tings inside.
  Simple I want to combine these two tables in a large table.
  
  Example:
  Table working_hours:
  Name - Date - hours-...
  Mr.A - 2.5.2011 - 8-...
  Mr.B - 2.5.2011 - 6-...
  C 2.5.2011 - 7-...
  
  Table times_absent:
  Name - Date - day-...
  Mr.A - 3.5.2011 - 1-...
  Mr.B - 3.5.2011 - 2-...
  Mr.B - 4.5.2011 - 2-...
  
  
  New Table:
  Name - Date - Working_Hours - Absent_Days-
  Mr.A - 2.5.2011 - 8 - null - or some sort of dummy value XXX
  Mr.A - 3.5.2011 - null-- 1
  Mr.B - 2.5.2011 - 6 - null.

  Is there a possibility in the OWB to perform this task?
  
  THX

  I did not understand your answer, but the OPERATOR PUT a couple IN a GROUP. What you need to do is connect your table 1 to table 2 for INgroup2 and INgroup1 (the two tables must have the same number and type of columns and the order is also important) and set your SET UNION operator, and that's all.

• Is mapping dimension AWM - possible to load the data in two tables of entry?

  Hi all
  
  I have two tables ProductFamily (parent level) and products (child level).
  
  I want to load a dimension of those tables where the parent-child relationships are maintained (I use AWM).
  
  I created a map with these two entry tables, but the loaded data has no relationship.
  So, how do I do that? Is it possible to load dimensions where different levels get data from multiple tables?
  Is any type of Carpenter available in AWM?
  
  Thank you
  
  ------------------------
  
  A few Notes:
  
  -I don't want to use OWB here that my data are clean
  -In AWM, when I loaded the data in a single view that contains two tables of input data, it worked fine. But it's my worst case option.

  You must use Dimension option in snowflake in the mapping screen of size for the Product Dimension (as opposed to the default style mapping - star schema dimension).

  This will modify map entries to include a separate parent for each level of hierarchy level / that is to say, for each level of hierarchy / (unless a higher level of the hierarchy), you must specify the parent level key in addition to the key current level, code/name/description/other attributes etc.

  You can make the mapping or... use the icons at the top of the map screen.
  mode drag/drop by dragging the relational column on dimension - level/hierarchy/attribute model
  -or-
  the table expression mapping mode that gives the same effect... by dragging a column on an attribute defined in the .

  Note1: Complete the mapping of a sudden... B & w switching mapping modes cause the mappings to reset.
  NOTE2: assumes that your data are correct foreign key table parent level: ProductFamily exists in the child level table: products.

• How to select a record in one table to manipulate data in a database?

  Hello community,

  Using 32-bit Labview 2015.

  I created a user interface that runs a query and retrieves my table from a sql database.

  I want to be able to manage only one record at a time by selecting the record in my table and then manipulate the data according to the needs.

  Whenever the user runs a query, I want as the first record in the table to be selected / highlighted.

  I want an indicator that is currently active.

  Then a click of a button, to be able to scroll the actively selected record.

  Once I have the selected record, I want a way to write a query to edit or delete the record.

  Is attached a photo of my query to select all of my table and connect data in my table (results).

  Attached a photo of my painting showing the timeline of my sql database.

  What is the best way to go on a record selection in a table and the modification of data with a query?

  Any help would be greatly appreciated.

  Thank you

  I guess that's not a table, but multi-column listbox.

  Right click, select--> highlight whole line selection Mode

  The value of the multicolumn listbox is the row index - you can write a local variable to highlight the line, the event structure to handle the user clicking on, etc.

  If you enable the property editable ListBox cells, you can allow users to edit the items of the listbox.

  If you want to get the data in row, you hint REF table and work with the array of strings in row - convert it to cluster, etc..

  I don't know, what type of data, it is, how you structure the database looks like, I don't even know if you use the wrapper to work with the database, I can't write queries for you.

  Something like Update Tablica Set Serial = '5' where ID = '22';

• Union two Tables

  Hello
  
  I have two tables with the same data structures and I want the two to the union. The problem I faced with union is the results are joined and it is difficult to distinguish which set of result belongs to which table:
  
  for example
  
  Select * from staff
  Union
  Select * from employees
  
  Jan - 06 Division
  Activity 10
  Company 4
  6 marketing
  Marketing 3
  5 finance

  Is there a way to display the above results like
  
  Jan - 06 Division
  "Staff".
  Activity 10
  6 marketing
  5 finance
  "Outgoing".
  Company 4
  Marketing 3

  The difference is there is a line break, showing the separation of staff and outgoing. Can anyone help?

• getting data between two tables

  Hi everyone, I need help with a query that seems simple, but I can't understand. consider the following data.

  with data as (

  s élire 802 cd from dual union all

  select 803 cd from dual union all

  select 804 cd from dual

  data2 as

  ( select 804 cd from dual )

  
  

  I want to join the two tables so that the result will be as follows:

  in the above data, we can see that 804 is common in both tables.  in this case, the output should be 804.

  Similarly, if 2 data include the following:

  data2 as

  ( select 804 cd from dual union all

  Select 803 cd from dual

  )

  
  

  the output is then 803 804.

  
  

  
  

  Now consider the following data
  

  with data as (

  s élire 802 cd from dual union all

  select 803 cd from dual union all

  select 804 cd from dual

  )

  take data2 table is empty

  
  

  I want to join the two tables, and in this case, the output should be 802,803,804.  data2 table is empty, then the default behavior is to get all the data in the data table. Since there is no line that corresponds to rows in the data table,

  the default behavior is to display output all data in the data table.  in this case 802,803,804
  

  can someone write a query for this?

  Hi Frank, thanks for the request.  These are very good questions. Here are the answers

  What happens if data2 rows, but none of them match data CD?

  It won't happen because the integrity of the data.

  ...

  I see it; a data line 2 will be in the data.  You have a FOREIGN KEY constraint, or something similar, so if cd = 804 exists in database2, then it must also exist in the data.

  What happens if the data is empty and data2 is not?

  If data is empty and data2 is not, then the data2 data should be released.

  for example

  with the data as)

  data table is empty

  data2 as

  (select cd 804 Union double all the)

  Select cd 805 double

  )

  When you join data and data2 account with the above data, then the output should be 804 805.  data2 data should be the display if the data table is empty. ...

  Doesn't that contradict what you said earlier?  Previously, it seemed to say that each row of data2 will be in the data, but now you give an example where all data2 lines are not in the data.

  If the first is true, then the solution in response #2 should work.

  If the latter is true, you can change the query like this:

  WITH got_r_num AS

  (

  SELECT NVL (d.cd, d2.cd) AS cd

  DENSE_RANK () (ORDER IN CASE

  WHEN d.cd IS NOT NULL

  AND d2.cd IS NOT NULL

  WHEN d.cd IS NOT NULL

  THEN 'B '.

  ANOTHER 'C '.

  DATA d

  FULL OUTER JOIN data2 d2 ON d.cd = d2.cd

  )

  SELECT cd

  OF got_r_num

  WHERE r_num = 1

• Valid time intervals: two tables intersect documents

  Benefits:

  I have two tables:

  AVAILABILITY (ALLOCATION A_ID, START_TIME, END_TIME, ID_RESSOURCE)

  TASK (T_ID, START_TIME, END_TIME, ID_RESSOURCE)

  My final request should print:

  Id_ressource, DAY_OF_WEEK, MYDATE, DURATION (in hours)

  Semantics back: "give me all the time slots available; Time slot available to the general public is the time range that does not contain a task"

  1. in the tables above START_TIME, END_TIME are of type DATE and they contain a timestamp that is to say:

  SELECT to_char (START_TIME, 'HH24 MMDDYYYY') from the AVAILABILITY/TASK

  would print something like

  09232014 14:17

  2. in the tables above time START_TIME and END_TIME are of the same date and END_TIME > START_TIME IE

  START_TIME = 09232014 14:17

  END_TIME = 09232014 15:17

  no need to check that

  3. If for some date there are TASK BOTH records and AVAILABILITY, then it must be:

  TASK. End_time < = AVAILABILITY. End_time and TASK. Start_time = > AVAILABILITY. START_TIME

  In other words, JOB registration is still "inside" free and BUSY folder

  I need time slots which are essentially output

  -All available records that do not contain a ' ' tasks.

  AVAILABILITY. Id_ressource, to_char (AVAILABILITY. Start_time, 'DAY') as DAY_OF_WEEK, AVAILABILITY. Start_time as MYDATE, (AVAILABILITY. END_TIME-AVAILABILITY. Start_time) * 24 as DURATION

  AND

  -If the free and busy folder contains task (see 3) then there are 2 two time intervals resulting (Yes the duration can be 0)

  AVAILABILITY. Id_ressource, to_char (AVAILABILITY. Start_time, 'DAY') as DAY_OF_WEEK, AVAILABILITY. Start_time as MYDATE, (TASK. START_TIME-AVAILABILITY. Start_time) * 24 as DURATION

  and

  AVAILABILITY. Id_ressource, to_char (AVAILABILITY. Start_time, 'DAY') as DAY_OF_WEEK, AVAILABILITY. Start_time as MYDATE, (AVAILABILITY. END_TIME-TASK. End_time) * 24 as DURATION

  Hope the above makes sense. What is the best, more rapid SQL?

  Hello

  Here's a way to do it:

  WITH union_data AS

  (

  SELECT id_ressource, change_time, change_val

  AVAILABILITY

  UNPIVOT (change_time

  FOR change_val IN (start_time AS 1

  end_time AS - 1

  )

  )

  UNION ALL

  SELECT id_ressource, change_time, change_val

  TASK

  UNPIVOT (change_time

  FOR change_val IN (start_time AS 1

  end_time AS - 1

  )

  )

  )

  got_change_sum AS

  (

  SELECT id_ressource

  change_time

  SUM (change_val) OVER (PARTITION BY id_ressource

  ORDER BY change_time

  ) AS change_sum

  Advance (change_time) OVER (PARTITION BY id_ressource

  ORDER BY change_time

  ) - change_time AS long

  Of union_data

  )

  SELECT id_ressource

  , TO_CHAR (change_time, 'fmDay, FMMM-DD-YYYY') AS available_date

  Duration * 24 AS available_hours

  OF got_change_sum

  WHERE change_sum = 1

  ORDER BY id_ressource

  change_time

  ;

  To see how it works, view the results of each auxiliary request individually.

  You will see that the union_data product has all the points where either avaialablity or a task changes.  The column change_val is + 1 availability or a task at the beginning and - 1, when it ends.  When the cumulative sum of those is 0, this means that there is no availability.  When the accumulated amount is > 1, this means a task is underway.  We are interested in the places where the cumulative sum of change_val is exactly 1, sense that a period which started (but not yet completed) and that there is a net 0 current tasks.

  This solution is NOT the value of start_time and end_time in the same day of calendar and tasks for the same resource may overlap.
