  There is no need to make a trade UNION for this:

  SELECT  *
  FROM    scott.maintenance
  WHERE   prod_id IN (1, 4)
  ;
  

  If you really need to do a UNION and basic tables were the same or had the same number and types of columns, then you can use SELECT * in the two branches of the UNION:

  SELECT  *
  FROM    scott.maintenance
      --
  UNION ALL
      --
  SELECT  *
  FROM    foo.maintenance
  ;
  

  If the columns have different names in the two tables, the names of the first branch of the UNION will be used in the output.

  In all cases, you can add literal NULL values to the SELECT one or more branches of the UNION clause:

  SELECT  ename     AS name
  ,       hiredate
  ,       deptno
  FROM    scott.emp
      --
  UNION ALL
      --
  SELECT  dname     AS name        -- alias not necessary, but helpful
  ,       NULL      AS hiredate    -- alias not necessary, but helpful
  ,       deptno
  FROM    scott.dept
  ;
  

  Depending on your tables and your requirements of yor, you might be able to use SELECT * in a branch of the UNION.

• with the clause with union all?

  Hello
  
  I tried to use 'by' article with union all. .but it gives me error...

  What harm am I doing here? Thank you very much!!

  Use the WITH clause, once for you all the subqueries, and then add the main request;

  with t1 as
   (select '1' col1
    from dual
    union all
    select '2' col2
    from dual),
  t2 as

  Any suggestions please

  You must replicate the columns that do not exist fill them with NULL values.

  Perhaps;

  create view eft_view as

           instant_amount,
           total_amount,
           source,
           inserted_date,
           cdc,
           cast (null as number) non_swept_amt,

  Hello

  That's what you asked for:

  select         Total_Customer_Qty,  NULL AS Total_Supplier_Qty,  Item_number,  Org,item_id  from table1;
  union all
  select NULL AS Total_Customer_Qty,          Total_Supplier_Qty,  Item_number,  Org,item_id  from table2;
  

  I hope that's what you want, too.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all tables and also post the results desired from these data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• Documentation about adding column with the DEFAULT value.

  Hello
  
  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14200/statements_3001.htm#i2198241
  
  < quote >
  If you add a column, then the initial value of each row in the new column is NULL unless you specify the DEFAULT clause. In this case, Oracle database updates each row in the new column with the value specified for the DEFAULT value. This update operation, in turn, triggers AFTER UPDATE triggers defined on the table.
  < quote >
  
  I am not able to understand the emphasis on the part AFTER UPDATE while the column with DEFAULT values addition triggers both BEFORE and AFTER triggers defined on UPDATE.
  
  According to the documents of 11 g
  
  http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_3001.htm#i2133105
  
  n.m. (u) r only changes with the NON NULL columns, but focus on AFTER UPDATE is still there. No trigger defined on the fire of the update in this case.
  
  This insistence is intended? If not, IMO, it should be changed.
  
  Kind regards

  Hi Sissi. After further discussion, we have added some information about a change in behavior. Here is what says the next version of the doc:

  When you add a column, the initial value of each row in the new column is null.

  * If you specify the DEFAULT clause for a column NOT NULL, then the default value is stored as metadata, but the column itself is not populated with data. However, the following queries that specify the new column are rewritten so that the default value is returned in the result set.

  This optimized behavior differs from earlier versions, when as part of operation ALTER TABLE Oracle database updated every line in the newly created with the default column and then fired defined update triggers on the table. In this release, no trigger is triggered because the default value is stored only in the form of metadata.

  * If you specify the DEFAULT for a nullable column clause, then the default value is added to existing lines under this ALTER TABLE statement, and any update triggers defined on the table are activated. This behavior also means if you change a NOT NULL column with a default value to be nullable.

  Hope that helps to clarify the matter further.

  Kind regards

• Poblem with union/union all giving ORA-22950

  I use a select statement with the xmlelement to create an xml file.
  
  There the various unions end in 5, but I always bring a line through.
  
  I do like that as then I can use this as a cursor in my plsql without having to create lots of cursors when I only need to use a.
  That is to say.

  SELECT  xmlelement("QUOTATION",xmlagg(xmlelement(Quotation,
                        xmlelement(CUSTOMERNAME, customername),
                        xmlelement(QUOTE,quoteid )))xmlfile
  From cust, quote
  where custid=quotecustid
  and ptype = 'Q'
  UNION
  SELECT  xmlelement("SALES",xmlagg(xmlelement(SALES,
                        xmlelement(CUSTOMERNAME, customername),
                        xmlelement(QUOTE,salesid )))xmlfile
  From cust, sales
  where custid=salescustid
  and ptype = 'S'

  Then, I use a cursor to execute it in a ftp file folder I selected passing ptype as a parameter.
  
  If I use the union I get ORA-22950 - I have seen other people use UNION all around it.
  If I use union all I'll get a value for the SALE of any line that is
  
  Any ideas how I can get around this as do not want to continue to create cursors

  The use of different sliders is always the best approach IMO.
  All things considered, it should be more effective than that appearing more "smart" one.

  And there is no need to be explicit cursors, it could just be SELECT INTOs wrapped in a PL/SQL CASE statement, with the appropriate exception handler (if necessary).

  Anyway, if you want to stick with the single-cursor method, there are different ways to do this:

  (1) adding a column selector:

  SELECT xmlfile
  FROM (
    SELECT 'Q' as selector
         , xmlelement("QUOTATION",xmlagg(xmlelement(Quotation,
                    xmlelement(CUSTOMERNAME, customername),
                    xmlelement(QUOTE,quoteid )))xmlfile
    From cust, quote
    where custid=quotecustid
    and ptype = :1
    UNION ALL
    SELECT 'S'
         , xmlelement("SALES",xmlagg(xmlelement(SALES,
                    xmlelement(CUSTOMERNAME, customername),
                    xmlelement(QUOTE,salesid )))xmlfile
    From cust, sales
    where custid=salescustid
    and ptype = :1
  )
  WHERE selector = :1
  ;
  

  (2) adding a GROUP BY clause, so that XMLAgg returns nothing if no row is selected:

  SELECT xmlelement("QUOTATION",xmlagg(xmlelement(Quotation,
                  xmlelement(CUSTOMERNAME, customername),
                  xmlelement(QUOTE,quoteid )))xmlfile
  From cust, quote
  where custid=quotecustid
  and ptype = :1
  GROUP BY null
  UNION ALL
  SELECT xmlelement("SALES",xmlagg(xmlelement(SALES,
                  xmlelement(CUSTOMERNAME, customername),
                  xmlelement(QUOTE,salesid )))xmlfile
  From cust, sales
  where custid=salescustid
  and ptype = :1
  GROUP BY null
  ;
  

  (3) subqueries:

  SELECT case :1
          when 'Q' then ( SELECT ... )
          when 'S' then ( SELECT ... )
        end as xmlfile
  FROM dual
  ;
  

• [8i] need help on query with a subquery/inline using UNION ALL view

  OK, first of all let's start with some background info:
  (1) I work in 8i
  (2) some samples for my problem (please excuse the additional columns of data not used to this problem; I already had the sample laying around tables):
  

  CREATE TABLE     vbom
  (
       part_nbr     char(25)     
  ,     bom_doc_nbr     char(25)     
  ,     bill_level     number

  );

  --part_nbr is your top level (0) parent
  --comp_part_nbr is the specific child
  --bom_doc_nbr is the parent of the child (comp_part_nbr) and may be either part_nbr or a child of part_nbr that is also a parent
  
  INSERT INTO vbom
  VALUES ('SAMPLE-1','SAMPLE-1', 1,'SAMPLE-2',1);
  
  CREATE TABLE     rqmt
  (
       comp_part_nbr     char(25)     
  ,     prnt_part_nbr     char(25)
  ,     ord_nbr          char(10)

  INSERT INTO rqmt

  INSERT INTO rqmt
  VALUES ('SAMPLE-2','SAMPLE-1','0000033294',001,5,0,TO_DATE('05/25/2010','mm/dd/yyyy'),'PL','DD');

  So, my first question was that I needed to find in the table RQMT who corresponded with everything on my VBOM have vbom.part_nbr table ' SAMPLE-1'. '. (Please note, in reality the VBOM table has thousands of rows of data, rather than just the 1 I have planned, some of them sharing the same vbom.part_nbr, others not). In addition to finding all RQMT data corresponding to the vbom.comp_part_nbr to vbom.part_nbr (where vbom.comp_part_nbr = rqmt.comp_part_nbr), I also need to find RQMT data for vbom.part_nbr itself (then, records where vbom.part_nbr = rqmt.comp_part_nbr).
  
  To resolve this problem, I started with the following query:

  SELECT     v.bill_level          AS bill_lvl
  ,     v.comp_part_nbr          AS component
  ,     v.bom_doc_nbr          AS parent
  FROM     VBOM v
  WHERE     v.part_nbr     ='SAMPLE-1'
  UNION ALL
  SELECT     0               AS bill_lvl
  ,     'SAMPLE-1'          AS component
  ,     NULL               AS parent
  FROM DUAL

  It allows me to add a line to the top of the page parent (vbom.part_nbr), which does not exist in vbom.
  My first question is, is UNION ALL of the best way to do it, or could I do a kind of instruction based on the line number box (or something) that would be better? (in this application, or in the final query)
  
  Then, I used the above query as a point of view online:

  SELECT     a.bill_lvl
  ,     a.component
  ,     a.parent
  ,     r.ord_nbr
  ,     r.sub_ord_nbr
  ,     r.qty_reqd
  FROM     (
       SELECT     v.bill_level          AS bill_lvl
       ,     v.comp_part_nbr          AS component
       ,     v.bom_doc_nbr          AS parent
       FROM     VBOM v
       WHERE     v.part_nbr     ='SAMPLE-1'
       UNION ALL
       SELECT     0               AS bill_lvl
       ,     'SAMPLE-1'          AS component
       ,     NULL               AS parent
       FROM DUAL
       ) a
  ,     RQMT r
  WHERE     a.component     = r.comp_part_nbr

  The problem here is that I have the same results (7 files) with the above query as I do with:

  SELECT     v.bill_level
  ,     v.comp_part_nbr
  ,     v.bom_doc_nbr
  ,     r.ord_nbr
  ,     r.sub_ord_nbr
  ,     r.qty_reqd
  FROM     VBOM v
  ,     RQMT r
  WHERE     v.comp_part_nbr     = r.comp_part_nbr
  AND     v.part_nbr     = 'SAMPLE-1'

  .. .it does not include RQMT recording for rqmt.comp_part_nbr = "SAMPLE-1'.
  
  To understand what was going on, I ran:

  SELECT     a.bill_lvl
  ,     a.component
  ,     a.parent
  FROM     (
       SELECT     v.bill_level          AS bill_lvl
       ,     v.comp_part_nbr          AS component
       ,     v.bom_doc_nbr          AS parent
       FROM     VBOM v
       WHERE     v.part_nbr     ='SAMPLE-1'
       UNION ALL
       SELECT     0               AS bill_lvl
       ,     'SAMPLE-1'          AS component
       ,     NULL               AS parent
       FROM DUAL
       ) a

  .. .and I get exactly this that I wait, 1 card for the SAMPLE-2 component and 1 plug for SAMPLE-1 (i.e. the recording I generated with the UNION ALL).
  
  Then I ran:

  SELECT     r.comp_part_nbr
  ,     r.ord_nbr
  ,     r.sub_ord_nbr
  ,     r.qty_reqd
  FROM     RQMT r
  WHERE     r.comp_part_nbr like 'SAMPLE-%'

  .. .and I get all 8 records, whose SAMPLE-1.
  
  So, it seems that the problem occurred when I join my opinion RQMT one online, although both separately seem to work very well.
  
  A point to note: all parts of parent and child may not be appointed in the same way as in my example. SAMPLE-1 could have children of the SAMPLE-2, abc123, 20735, for example.
  
  Any help on this would be appreciated, thanks!

• How to fill a column with numbers and maintain when adding or deleting lines?

  So far, I've discovered two ways to fill a column with the number:

  1. Enter '1' in a single cell, '2' in the one below, select both, and then use the yellow dot to drag down - it will do the rest.

  2 create a formula such as 'A2 + 1' and drag also.

  However, in both cases it will work if I manually this continues to do for each newly added line at the bottom. Now, that alone would not be that big of a problem if it wasn't for the fact that I'm working with a table where the lines can be added among other rows in the future.

  Having said that, could someone please tell me how to create a column with a number that will increase automatically? I mean - if I add a new line between line 56 and 57, I want the new line to have a '57"in it, and the" old 57 "would now be"58"and so on." " I don't want to drag the whole column, which can be hundreds if not more than a thousand lines.

  Try to put this in the cells in the column:

  = ROW()

  In the formula, you can add or subtract a number if necessary to get the starting number that you need.

• Why UNION ALL allows no column names only when a literal is used and there is at least 3 parts of the query?

  An artificial union all:

  SQL> SELECT Dummy FROM Dual ORDER BY Dummy;
  
  D
  -
  X
  
  SQL> SELECT Dummy FROM Dual UNION ALL SELECT Dummy FROM Dual ORDER BY Dummy;
  
  D
  -
  X
  X
  
  SQL> SELECT Dummy FROM Dual UNION ALL SELECT Dummy FROM Dual UNION ALL SELECT Dummy FROM Dual ORDER BY Dummy;
  
  D
  -
  X
  X
  X
  
  
  

  It literally changes it:

  SQL> SELECT NULL A FROM Dual ORDER BY A;
  
  A
  -
  
  
  SQL> SELECT NULL A FROM Dual UNION ALL SELECT NULL FROM Dual ORDER BY A;
  
  A
  -
  
  
  
  SQL> SELECT NULL A FROM Dual UNION ALL SELECT NULL FROM Dual UNION ALL SELECT NULL FROM Dual ORDER BY A;
  SELECT NULL A FROM Dual UNION ALL SELECT NULL FROM Dual UNION ALL SELECT NULL FROM Dual ORDER BY A
                                                                                                   *
  ERROR at line 1:
  ORA-00904: "A": invalid identifier
  
  
  SQL> SELECT NULL A FROM Dual UNION ALL SELECT NULL FROM Dual UNION ALL SELECT NULL FROM Dual ORDER BY 1;
  
  A
  -
  
  
  
  
  

  Why 3 is the magic number?

  My friend, this is what I would call a "bug".

  However, my opinion doesn't matter, because I do not work for Oracle

• 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

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

  This one will work.
