Select different columns using union all

I'm trying to select all the records of two table

Select A, B, C from table1
Union of all the
Select A, B, D, E, F from table2

I get results A, B, C columns but not D, E, F.

What should I do to get all the columns in the result. as A, B, C, D, E, F

Thank you

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.

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.

[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          
,     comp_part_nbr     char(25)     
,     qty_per          number
);
--technically has primary and foreign keys, but whatever...
--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)     
,     sub_ord_nbr     char(3)
,     qty_reqd     number
,     qty_issued     number
,     date_reqd     date
,     rqmt_stat     char(2)
,     rqmt_type     char(2)
);

INSERT INTO rqmt
VALUES ('SAMPLE-1','','S0000TEST1',001,30,0,TO_DATE('06/01/2010','mm/dd/yyyy'),'AL','ID');
INSERT INTO rqmt
VALUES ('SAMPLE-2','SAMPLE-1','0000054963',001,15,10,TO_DATE('04/01/2010','mm/dd/yyyy'),'CL','DD');
INSERT INTO rqmt
VALUES ('SAMPLE-2','SAMPLE-1','0000032562',001,5,5,TO_DATE('04/15/2010','mm/dd/yyyy'),'IS','DD');
INSERT INTO rqmt
VALUES ('SAMPLE-2','SAMPLE-1','0000022341',001,5,4,TO_DATE('04/20/2010','mm/dd/yyyy'),'SH','DD');
INSERT INTO rqmt
VALUES ('SAMPLE-2','SAMPLE-1','0000043469',001,10,0,TO_DATE('04/30/2010','mm/dd/yyyy'),'AL','DD');
INSERT INTO rqmt
VALUES ('SAMPLE-2','SAMPLE-1','0000071235',001,10,0,TO_DATE('05/01/2010','mm/dd/yyyy'),'OP','DD');
INSERT INTO rqmt
VALUES ('SAMPLE-2','SAMPLE-1','0000061224',001,5,0,TO_DATE('05/15/2010','mm/dd/yyyy'),'FP','DD');
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!

Hello

Concerns of problem by comparing 8 literal characters ' SAMPLE-1' for the 25-character CHAR column that contains "SAMPLE 1".»
17 spaces including the literal or use LPAD or CAST to 25 characters.
For example:

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
     ,     CAST ('SAMPLE-1' AS CHAR (25))               -- CAST added here
                                  AS component
     ,     NULL               AS parent
     FROM DUAL
     ) a
,     RQMT r
WHERE     a.component     = r.comp_part_nbr
;

Is there a reason why you use CHAR instead of VARCHAR2? (One reason other than "I can't change it now.", otherwise said.)

Elimination of unnecessary case statements

Select the column using
Hello

I have a report with 4 columns, 'Year', 'Demand amount', 'Amount of the purchase order' and 'invoice amount.

The user want to select "Amount of demand", "The purchase order amount" or "Invoice amount" in the drop down menu from the drop in the Oracle replies

In other words, he wants to see only the year and "amount of demand."
year or "amount in the purchase order.
year or "amount of the invoice.

How can I do? I already search column, select but did not understand. Please tell me in detail.

Thank you
Hello user.

I advise to use the column picker in the responses.

(1) build your table (or any other point of view) a year and the amount of the claim.
(2) then create a view by using the choice of mode 'column selector.
(3) check the checkbox 'Include the selector' for your column 'amount of demand. "
(4) add the other two columns in the selection pane. Your view should look like the image below:

! http://i46.Tinypic.com/2gwyfso.jpg!

5) go to your compound view and add your views 'column selector.

You should now be able to Exchange "Amount of demand", "The purchase order amount" and "Amount of the invoice" using the column Chooser, and your other points of view should replace columns that you select.

I hope this helps and please assign points if you found it useful!

Kind regards
Jason

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

You opened a SR with Oracle?

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
;

Union all with addistional field

Hello
Maybe this is a stupid question.
I have two tables with 22 columns.
Another table with 23 columns
I want to combine these two tables using union all.
In the first picture, I want back "NA" as the last field.
In the second table, last column is varchar2.
Instead of every column one by one and if I use select * in two queries and add "NA" to one?
I want the union two queries can order and use it with the clause to retrieve values based on conditions somany.
So I have to specify the names of column three times.
I use oracle 10g

Hello Krishna,

Try

UNION and UNION ALL giving multiple result sets even if INTERSECT does not lines.

Hello
I have a set of two queries. I used the UNION to join the result set. When I used UNION ALL, I get a different result set.
BT when I use INTERSECT, I m not getting all the lines.
SO, which I guess is, as operation INTERSECT isn't Govind all the lines, then the UNION and UNION ALL of the result sets must be simliar.
But I m getting different result sets.
Please guide me.
Thank you.

Hello

UNION returns separate lines; UNION ALL returns all rows that produce queries.

INTERSECT has nothing to do with it. You can have the lines in a single query. For example

Job SELECTION

FROM scott.emp

UNION - ALL THE

SELECT 'FUBAR '.

DOUBLE;

In this example, there is no overlap between the 2 queries (INTERSECT would have 0 rows).

UNION produces 6 lines, because the query at the top of the page produces 5 distinct lines (of 14 total ranks) and the background query 1.

UNION ALL product lines 15: 14 of the request from top and 1 of the request from the lower part.

I hope that answers your question.

If not, post a test script (if necessary) and complete, including some UNION, UNION ALL queries INTERSECT. Post of the CREATE TABLE and INSERT statements for all tables using those queries (with the exception of the commonly available rtables, such as those of the scott schema) and a specific question, such as "the UNION query all product...» I expect the UNION query to produce... because... but instead, it produces... Why is this? It seems contractict... manual which says that... ».

Union all too slow for my query any alternative?

Hello

The following query prints the desired results. What I'm trying to do is to add to my query below is to also retrieve information from different dates (for example 01.01.2012 - 30.4.2012), more information below, but with 0 amounts. The only solution I found is to duplicate the query to a union and entry dates you want below. The problem is that, then the query is too slow.
Any other recommendations are welcome

SELECT s.trans_datetime,s.alloc_ref,s.accnt_code,s.treference,s.DESCRIPTN,sum(s.amount*(-1)) as amount,s.conv_code,sum(s.other_amt*(-1)) as other_amt,s.anal_t1,ss.descr,
o.NTN_DESCR as flag,z.name as vessel_name
FROM  accounts s, customers ss,vessel a,nation o, analysis  z,
customers_anl_cat  z1
where s.trans_datetime BETWEEN to_date('01.01.2013','DD.MM.YYYY') AND to_date('30.04.2013','DD.MM.YYYY')
AND s.accnt_code=z1.acnt_code
AND z1.anl_cat_id=17
AND ss.ACNT_TYPE=2
AND s.accnt_code=ss.acnt_code
AND o.NTN_CODE=a.flg_code
AND z.anl_code=s.anal_t1
GROUP BY s.trans_datetime,s.alloc_ref,s.accnt_code,s.treference,s.DESCRIPTN,s.conv_code,s.anal_t1,ss.descr
,o.NTN_DESCR,z.name,z1.anl_code

Thanks in advance

Thank you very much for your answers.

Unfortunately, the lines of the new date in the amount and need to convert to 0 or null values

OK... What is not eligible for a situation to replicate the query to use UNION all clause You can simply do more in select:

Select  column_list1... column_listN,
case when s.trans_datetime BETWEEN to_date('01.01.2013','DD.MM.YYYY') AND to_date('30.04.2013','DD.MM.YYYY') then s.amount
       when s.trans_datetime BETWEEN to_date('01.01.2012','DD.MM.YYYY') AND to_date('30.04.2012','DD.MM.YYYY') then 0
end amount
from table_names
where (s.trans_datetime BETWEEN to_date('01.01.2013','DD.MM.YYYY') AND to_date('30.04.2013','DD.MM.YYYY') or s.trans_datetime BETWEEN to_date('01.01.2012','DD.MM.YYYY') AND to_date('30.04.2012','DD.MM.YYYY'))

How to upgrade a table column using the values in the Oracle collection

create or replace procedure test_coll

IS

CURSOR upd 
IS
SELECT CONTACT_NAME FROM Supplier_16;

TYPE dept IS TABLE OF upd%rowtype;
cur_var dept;

Type List Is table Of  varchar2(20);
Name List:=  List('Shilpi','Sunil','Shreyas','Saral');

BEGIN

OPEN upd;
LOOP
     FETCH upd BULK COLLECT INTO cur_var;
--    EXIT WHEN upd%NOTFOUND;

     FORALL i IN cur_var.FIRST..cur_var.LAST
  
     UPDATE supplier_16
**  SET Contact_name= name(i);  ***
     
     COMMIT;

END LOOP;
CLOSE upd;

END;

On the "BOLD" line, I don't know how I should move the values of the collection of name I said without which are set all the values in the table supplier_16 = 'Saral.

Help, please.

Yes, I slide collections and was trying to reach somwthing on similar lines to which you provided the code example...

My essay is equipped to take a collection: initialized with values of say 3-4...

Take other tables... A column... and update the column in the table (not PK, FK anything) using the values of the initialized collection...

However, I am stuck between the two on how the UPDATE clause should be...

OK, if it's just because you want to practice with collections, you might do something like this...

SQL> set serverout on
SQL> create table supplier_16 as
  2  select 'Frederick' as contact_name from dual union all
  3  select 'Robert' from dual union all
  4  select 'Jeremy' from dual union all
  5  select 'Simon' from dual
  6  /

Table created.

 18       DBMS_OUTPUT.PUT_LINE(v_contact_name||' update to '||name(v_idx));
 19       v_idx := v_idx + 1;
 20    END LOOP;
 21    CLOSE upd;
 22    COMMIT;
 23  END;

Of course, there is treatment rank by rank and is not best for performance, but it allows you to access your collection that you created names.

can we use to_date using Union or Union
Hi, while I do any union with two tables I get

ORA-01790: expression must have same type of data, matching expression
01790 00000 - "expression must have the same type of data, matching expression.

and if I change this data type of TO_CHAR is showing correct result

SELECT (TO_CHAR (C61_CURRENT_MONTH, ' MON-DD-YYYY "") CURRENT_MONTH EDW.) C$ _0VW_TEMP_PLAYER_DTL_LOAD
UNION ALL
SELECT (TO_CHAR (C17_CURRENT_MONTH, ' MON-DD-YYYY "") CURRENT_MONTH EDW.) C$ _1VW_TEMP_PLAYER_DTL_LOAD

and I'm going to insert this result in a table which column is defined as the DATE data type

so I tried below one as

Select to_date (TO_CHAR (C61_CURRENT_MONTH, ' MON-DD-YYYY ""), 'dd-mon-yyyy') CURRENT_MONTH OF EDW. C$ _0VW_TEMP_PLAYER_DTL_LOAD
UNION ALL
TO_DATE (TO_CHAR (C17_CURRENT_MONTH, ' MON-DD-YYYY ""), 'dd-mon-yyyy') CURRENT_MONTH OF EDW. C$ _1VW_TEMP_PLAYER_DTL_LOAD

but I get the error message like

ORA-01790: expression must have same type of data, matching expression

so my question is can we use to_date using union all.
Maybe do you the conversion to remove time from date values.

This could be done better with:
```
select trunc(C61_CURRENT_MONTH) CURRENT_MONTH FROM EDW.C$_0VW_TEMP_PLAYER_DTL_LOAD
UNION ALL
select trunc(C17_CURRENT_MONTH) CURRENT_MONTH FROM EDW.C$_1VW_TEMP_PLAYER_DTL_LOAD
```
I can't reproduce your original error, because I do not have your tables (test data would be nice)
and no doubt I'm on another database-version (we do not know your version of db).

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

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

1 Mickey 450 0

2 Donald 750 0

Select different schema data

I have 3 users in the schema.
User09
User10
User11
PURCHASE table name exists in all these three schema with different data (depending on date)
As
User09-> purchase - data date Jan09 to dec09
User10-> purchase - data date Jan10 Dec10
User11-> purchase - data date Jan11 Dec11

I want to choose * purchase, on any user select three with education.

I choose data with union all

select * from user09.pruchase Union all
select * from user10.pruchase Union all
select * from user11.pruchase

It is a problem: -.
After you create this query I have add another utilisateur12 user and that the user has the same purchase table so I'll have to add another line IN Union all question them.

When I see this query. It gives me the name of all the owner of User09, User10, User11...

SELECT * FROM ALL_ALL_TABLES
WHERE OWNER LIKE 'USER%'
and table_name ='PURCHASE'

OWNER                          TABLE_NAME                     TABLESPACE_NAME                
------------------------------ ------------------------------ ------------------------------ 
USER                            PURCHASE                       USERS                         
USER09                          PURCHASE                       USERS                         
USER10                          PURCHASE                       USERS                         
3 rows selected

Can I get purchase data Table of all users with the statement select.

Line 17 must be
