  There will be several lines in the table of SALES with different SALETYPEs. There may be several lines in the table RETURNS, corresponding to some of the points of SALE. RETURNS the table has a foreign key to the SALE. The report that I am trying to generate with a select sql statement must include a line for each type of sale (from table SALETYPE) and the sum of sale amounts corresponding to this type of sale of the SALES table. The table may not return the entries for all types of sales and the amount of Scripture must be reported as zero. The SQL I use is below, but does not work. I hope that I have explained this correctly. Please see the doc attached for typical data that I work with. Can someone please?

  Hello - the second displays almost had. what you want to do is joining several tables at once - impossible with the syntax of the oracle, but possible if you use ANSI SQL.

• Join several Tables versioned

  Hello

  We are working on a data warehousing project and wonder how do to join several tables that each are versioned separately (type SCD 2 with a valid and valid to date).

  Because for example, we get our client from a single source of information (id customer, name, etc.) and the information on the rate of customer from another source.  The sources are different, we have the separate tables for them and each of them gets versioned independently.

  Here's my customer table (with its own valid and valuable to the columns).

  ID	Name of the customer	Valid from	Valid until the
  1	CitiBank	1 JANUARY 14	JANUARY 1, 15
  1	New CitiBank	2 JANUARY 15	FEBRUARY 1, 15
  1	Latest CitiBank	2 FEBRUARY 15	APRIL 1, 15

  And similarly the Client side ID and rating information.

  ID	Note	Valid from	Valid until the
  1	Platinum	1 JANUARY 14	FEBRUARY 1, 14
  1	Premium	FEBRUARY 1, 14	1ST MARCH 15

  I want to merge the two tables above and present information at a glance.  I have some difficulty to determine validates the valid columns.

  ID	Name of the customer	Note	Valid from (Calculated)	Valid until the (calculated)
  1	CitiBank	Platinum	1 JANUARY 14	FEBRUARY 1, 14
  1	CitiBank	Premium	FEBRUARY 1, 14	JANUARY 1, 15
  1	New CitiBank	Premium	2 JANUARY 15	FEBRUARY 1, 15
  1	Latest CitiBank	Premium	2 FEBRUARY 15	1ST MARCH 15

  And it's the query I used to get the above result:

  SELECT client. id ,

         customer . name ,

         CRM . level ,

         Greatest (client. vld_fm , crm. vld_fm ),

         Least (client. vld_to , crm. vld_to )

  DE    client client,

         client_rating crm

  OÙ   client. id = crm. id

         AND ( client. vld_fm <= crm. vld_fm

               AND client. vld_fm <= crm. vld_to

               AND client. vld_fm >= crm. vld_fm

               AND client. vld_fm >= crm. vld_to )

          OR ( client. vld_fm BETWEEN crm. vld_fm AND crm. vld_to )

          OR ( client. vld_to BETWEEN crm. vld_fm AND crm. vld_to );

  
  

  
  The problem is we have several data sources (and each with its own versions) and joins become so very very complex.  Is there a better way to write the query?

  Or maybe a better way to design our tables?

  Thanks for your help.

  Hello

  you only need ranges that overlap to join.

  Re: How do to sql query in a loop

  Is a simpler way to test if the x_start to x_stop range comes into conflict with the range of y_start to y_stop

  WHERE     x_start <= y_stop AND     y_start <= x_stop
  

  In other words, two overlapping if and only if everyone will start before the other ends one. If this is not obvious (and it was certainly not clear to me when I heard it), then look at it this way: two ranges are not overlapping if and only if one of them starts after the end of the other.

• joining several tables to generate data

  with itemlist as

  (select 1 cid, listname 'test', 'r' flg Union double all the)

  Select 2 cid, listname 'test2', ' not flg double

  ),

  category 1)

  Select 1 cid, 122 k' sub '123' catcode, of any double Union

  Select 1 cid, '234i' catcode, sub '124' all Union double

  Select 1 cid, 238 k' void '124' catcode, double

  )

  void)

  Select 1 cid, sub '123' of any union double

  Select 1 cid, sub ' 124' double

  )

  I want to write a static query that gathers all the tables and produces the following output assuming that

  CID is you pass as a parameter

  CID listname flg topic catcode

  1 123 122 k r test

  1 test of r 234i 124

  1 124 238 k r test

  Suppose the data as changes to follow and even cid 1 is to pass as a parameter:

  with itemlist as

  (select 1 cid, listname 'test', 'r' flg Union double all the)

  Select 2 cid, listname 'test2', ' not flg double

  ),

  category 1)

  Select 1 cid, 122 k' sub '123' catcode, of any double Union

  Select 1 cid, '234i' catcode, sub '124' all Union double

  Select 1 cid, 238 k' void '124' catcode, double

  )

  void)

  Select 2 cid, sub '123' of any union double

  Select 2 cid, sub '124' double

  )

  then the output should be

  CID listname flg topic catcode

  1 r test 123

  1 test of r 124

  1 test of r 124

  for a final example, suppose the data now as to user 1 as cid

  with itemlist as

  (select 1 cid, listname 'test', 'r' flg Union double all the)

  Select 2 cid, listname 'test2', ' not flg double

  ),

  category 1)

  Select 2 cid, 122 k' sub '123' catcode, of any double Union

  Select 2 cid, catcode '234i', '124' void in any union double

  Select 2 cid, 238 k' void '124' catcode, double

  )

  void)

  Select 1 cid, sub '123' of any union double

  Select 2 cid, sub '124' double

  )

  output must be

  CID listname flg topic catcode

  1       test            r                 123

  Basically, the user will pass a cid, in this case 1. I'll read the itemlist where cid = 1 and I want to join all the other tables

  to itemlist in such a way that I can generate extra lines.  If no entry is found for cid 1, for example, in category 1 or auxiliary table

  then the beloging column of this table must be null in the result

  can someone help me write a query to produce the output above

  Hello

  elmasduro wrote:

  ...

  Here is an explanation of the output.  a user will have a front screen where it can enter itemlist info.
  then in a submenu may enter a category or sub or both or none of them. the user can select multiple categories or sub
  When the user presses the button Save, an entry will be made in the itemlist table, for example the cid = 1.
  If he choose a category but without Subs, then will be entered into the table at say cid = 1

  
  but no entries will be made for sub because he chose not to all values.  If he chooses void instead of category values
  then sub taable will fill and category is not. If he chooses the category and under, then both will be filled.

  what I want to do is to join the itemlist with table category and sub table and get the data to the Scriptures, this intervention of the user.
  These entries not found will be the null value column in the result.
  for example, the cid = 1 itemlist, if user enter category but not void, itemlist will be the join with the table category and sub
  but since sub has no entry for the cid = 1, the column object will be empty in the output, but catcode will fill

  I'm so confused.

  It is a query (that is, just a SELECT statement, which shows the data already present in the tables), or is this a DML statement, that will add data to the tables?  If it's just a query, then do not say things like "entries will be taken" or "filled with tables.

  Assuming you want a request maybe you want something like this:

  WITH c_and_s AS

  (

  SELECT NVL (c.cid, s.cid) AS cid

  NVL (c.sub, s.sub) AS topic

  , NVL2 (s.cid, c.catcode, NULL) AS catcode

  CATEGORY 1 c

  FULL OUTER JOIN void s ON c.cid = s.cid

  AND c.sub = s.sub

  )

  SELECT i.cid, i.listname, i.flg

  cs.subject, cs.catcode

  Itemlist I have

  LEFT OUTER JOIN c_and_s ON cs.cid = i.cid cs

  WHERE the i.cid (1) - you can do the cids 2 or several at the same time, if you want to

  ORDER BY i.cid, cs.subject, cs.catcode

  ;

  This example gets the output you asked data sample you posted.

• How to join several tables source and do the research?

  I have a requirement to load a target table by joining 4 source tables. Also, I do a search on a field of table to transform codes and check for NULL values. What will be the best approach for load table target?
  Is it possible to do it in a single interface, or do I need to create multiple interfaces to achieve this?
  
  My basic source and target are oracle, and I am planing to use incremental update Oracle merge.
  
  Thank you

  You are in the right direction by creating an interface for this transformation.
  You will need to drag the source drop 4 tables + the lookup table in the Sources of Interface window and then make the appropriate joins.
  Also, look for NULL values in the transformation. Depends on what you want to do with NULL values. If you want to ignore, use a filter.
  If you want to make mistakes, use a constraint.
  If you want to convert them, use NVL

  Start with Oracle Update incremental and once successful, use incremental update Oracle MERGE.

  Kindly help me with this. Thank you in advance for your time and effort.

  Hello

  I see your table TT3 has duplicated lines. A reason for this?

  Rather than run a separate, I created it without duplicated lines:

  create table TT3(FeesCntlr,CommCntlr,LatePayCntlr,Name,Age) as select
  1,11,21,'Mike',25 from dual union all select

  7,15,25,'Batty',45 from dual union all select
  8,16,26,'Nicky',38 from dual;
  
  create table TT4(FeesCntlr,CommCntlr,LatePayCntlr,Fees,Commission,Latepayment) as select

• Join several tables of two different patterns - is it possible?

  If this is the case, what are the measures?
  
  THX

  This is the case.

  You must prefix the tables with the schemaname tables is in, or create a synonym for the table. In addition, you must grant select rights from of a the reference schema owner schema:

  SELECT A.*,B.*
    FROM SCHEMA1.TEST_TABLE A,
         SCHEMA2.TEST_TABLE B
   WHERE somecondition
  

• Outer join complete Multi Table

  What is the syntax to make a full outer join on three tables. All the examples I can find use using the clause, but in my case, the column names are not the same in the three tables

  Hello

  Use IT instead of USE.

  Assuming that all the 3 tables will have a common value in a column (whatever it is called):

  ...
  FROM           table_x  x
  FULL OUTER JOIN      table_y  y     ON     y.idy     = x.idx
  FULL OUTER JOIN      table_z  z     ON     z.idz     = COALESCE (x.idx, y.idy)
  

  When comes the time to join table_z, you won't know which of the previous tables match, so you must use COALESCE to try them all.

  If you need to join several tables in this way, the expression of COALESCE for the nth table will have (n - 1) arguments.

• Join the tables in the responses

  I would like to know if it is possible to join the tables together as below in the answers?
  
  Select a.Field1, b.Field1
  FROM tableA an outer join left tableA b on
  a.Field1 = b.Field

  If you want to make an INNER JOIN, and then type INNER JOIN instead of LEFT INNER JOIN.

  If you want to left outer join and LEFT OUTER JOIN instead of INTERNAL LEFT JOIN type.

  Nothing asked as a left inner join. That is why it gives error + [nQSError: 27002] near +.

  Thank you

• Using Left Outer Join with reference

  I have three tables.
  Table 1: BOOK_DETAILS
  Fields: BOOK_ID, BOOK_NAME
  
  Table 2: BOOK_ISSUE_RECORD
  Fields: BOOK_ID, USER_NAME
  
  Table 3: BOOK_AUTHOR
  Fields: BOOK_ID, AUTHOR_NAME
  
  I must link table 1 and table 2 with a left outer join, because even if the book is not the questions to anyone, his name should come.
  I have once again display the name of the author of books for each book.
  I am able to create a query with the left outer join between table 1 and table 2. However, I am not able to give a reference to Table 3.
  Can someone help me with this please.
  
  Concerning
  Hawker

  select  d.book_name,
          a.book_author,
          i.user_name
    from       book_details d
          join
               book_author a

• using (+) or left outer join

  Dear Expert;
  
  I've been playing by using the two symbol... and realized that they do the same thing... Is it true...? or am I wrong.
  
  Thank you.

  Hello

  They all have two outer joins. The + rating was the original way to do it in Oracle. LEFT, RIGHT, and FULL OUTER JOIN introduced in Oracle 9, but the old way is still supported.

  There are some situations (such as an outer join complete and outer-join a table to two different tables) that are better with the ANSI syntax (it's LEFT OUTER JOIN). It is possible to get the same results using +, but it must be combersome and/or inefficient workarounds. I suggest that you use always LEFT OUTER JOIN (or FULL OUTER JOIN, or, on occasions RIGHT OUTER JOIN). I think that you will find it easier and less error-prone.

• Create a trigger instead of update several tables in a view

  Dear everybody
  
  I am trying to create a trigger that updates instead of to day joined several tables in a view, but I can't get my trigger to work. The create view command was as follows:

  CREATE OR REPLACE VIEW VIEW_MI_JOIN_GC
  AS
  SELECT MAP_INDEX.mi_prinx,
         index_type_id,
         original_map_publication_id,
         original_map_sheet_number_id,
         name_of_feature,
         geog_coordinates_id,
         GEOG_COORDINATES.mi_prinx AS "mi_prinx_polygon",
         GEOG_COORDINATES.geographical_coordinates,
         GEOG_COORDINATES.mapinfo_style_row
   FROM MAP_INDEX
    JOIN GEOG_COORDINATES
     ON geog_coordinates_id=GEOG_COORDINATES.mi_prinx;

  The view above connects a polygon table to the table of function names which means that a polygon appears several times in a view, even though one version of the polygon exists in the base table. This means the direct update of view cannot take place, since 1 polygon can appear multiple times in a view. The two original base tables and their columns names are:

  MAP_INDEX
  ---------
  MI_PRINX
  INDEX_TYPE_ID
  ORIGINAL_MAP_PUBLICATION_ID
  ORIGINAL_MAP_SHEET_NUMBER_ID
  NAME_OF_FEATURE
  MAPINFO_STYLE_ROW
  GEOGRAPHICAL_COORDINATES
  GEOG_COORDINATES_ID
  
  GEOG_COORDINATES
  ----------------
  MI_PRINX
  GEOGRAPHICAL_COORDINATES
  MAPINFO_STYLE_ROW

  Relax, I created was as follows:

  CREATE OR REPLACE TRIGGER TRIG_VIEW_MI_JOIN_GC
     INSTEAD OF UPDATE ON VIEW_MI_JOIN_GC
        REFERENCING NEW AS NEW
   FOR EACH ROW
  BEGIN
   UPDATE MAP_INDEX
    SET mi_prinx = :NEW.mi_prinx,
        index_type_id = :NEW.index_type_id,
        original_map_publication_id = :NEW.original_map_publication_id,
        original_map_sheet_number_id = :NEW.original_map_sheet_number_id,
        name_of_feature = :NEW.name_of_feature,
        mapinfo_style_row = :NEW.mapinfo_style_row,
        geographical_coordinates = :NEW.geographical_coordinates,
        geog_coordinates_id = :NEW.geog_coordinates_id
     WHERE geog_coordinates_id = :OLD.geog_coordinates_id;
   UPDATE GEOG_COORDINATES
    SET mi_prinx = :NEW.mi_prinx,
        geographical_coordinates = :NEW.geographical_coordinates,
        mapinfo_style_row = :NEW.mapinfo_style_row
     WHERE mi_prinx = :OLD.mi_prinx;
  END;
  /

  The idea is that when I draw a new polygon in MapInfo and assign him a revised number geog_coordinates_id and the number of mi_prinx_polygon, which are the same, once I have save the view as then it updates the underlying tables. Geographical_coordinates and mapinfo_style_row of map_index table columns are columns with ancient polygon data which while not having currently new data inserted into them, are required for the previous data they contain. These data are currently being added to the geog_coordinates table with other scripts. The idea is that all the data is then read using a view and updates made to the view, triggering instead of relaxing, so data are not duplicated but still visible as if it were.
  
  When I created first the relaxation above in SQLdeveloper it seems to run constantly. Then my computer crashed, not related to this work, and I lost session because I did not commit it. I was not ready to commit it because I believe that something is wrong.
  
  I am in the trigger syntax correctly and I go about it in the right way? I want to only update the rows that have changed, that's why I was using: NEWS and: OLD.
  
  Kind regards
  
  Tim
