XQuery with Union
As I am not able to use IF-ELSE in Oracle for select statements, I use to get rid of a select set of query results and UNION to get the results of other queries set according to the value of the parameter.Example of a normal query:
Select FNAME LNAME from EMP where Param.1 in ('NAME', 'NAME')
UNION
SELECT CITY, ADDRESS from EMP where Param.1 in ('LOCATION', 'ADDRESS')
When I give Param.1 as 'NAME', it gives me the results of the first query set while it ignores another query resultset will null coz Param.1 isn't in "Position" or "ADDRESS".
Same Wau if I give Param.1 'Address', this is for me the result set of a query resultset 1 2nd query and spread as it is null.
But the same approach doesnot work to query Oracle with Xquery that follows:
Select rtrim (XMLELEMENT ("lines", XMLAGG (RW.column_value)), ',') stopped
EMPTABLE UL, XMLTABLE (' sets of lines/lines/lines ' UL of PASSAGE. ") TEXT) AS RW
WHERE
[Param.1] IN ('NAME', 'NAME')
UNION
Select rtrim (XMLELEMENT ("lines", XMLAGG (RW.column_value)), ',') stopped
ADDRESSTABLE UL, XMLTABLE (' sets of lines/lines/lines ' UL of PASSAGE. ") TEXT) AS RW
WHERE
[Param.1] IN ('LOCATION', 'ADDRESS')
Here, if the Param.1 is "NAME" then the results in the form < all > < / lines > + out of another query (that thing I want)
How can I remove this < Rowset > < / lines > output?
As I am not able to use IF-ELSE in Oracle for select statements
How about a CASE statement?
If every query is always supposed to return only a single grouped column (and of course a single line), you can use this:
SELECT CASE WHEN param_1 IN ('VAL1', 'VAL2')
THEN (
SELECT ...
FROM emptable, XMLTable( ... )
)
WHEN param_1 IN ('VAL3', 'VAL4')
THEN (
SELECT ...
FROM addresstable, XMLTable( ... )
)
END AS Orders
FROM dual;
If you prefer that the approach of the UNION, then:
Here, if the Param.1 is 'NAME' then results such as
+ out of another query (that thing I want)
It is because of the aggregation XMLAgg function.
An aggregate without GROUP BY function always returns a line, even if there is no line in the original game.
SQL> SELECT XMLElement("Rowset", XMLAgg(rw.column_value))
2 FROM emptable ul
3 , XMLTable('/Rowsets/Rowset/Row' passing ul.text) as rw
4 WHERE 1 = 0
5 ;
XMLELEMENT("ROWSET",XMLAGG(RW.
--------------------------------------------------------------------------------
You can group into an empty list of column to force the required behavior:
SQL> SELECT XMLElement("Rowset", XMLAgg(rw.column_value))
2 FROM emptable ul
3 , XMLTable('/Rowsets/Rowset/Row' passing ul.text) as rw
4 WHERE 1 = 0
5 GROUP BY ()
6 ;
XMLELEMENT("ROWSET",XMLAGG(RW.
--------------------------------------------------------------------------------
You must also use UNION ALL instead of UNION whereas Oracle doesn't bother doing the a unnecessary sort operation.
What is the purpose of RTRIM in your examples? I see no reason to call it on an instance of XMLType, in addition, it performs a type conversion from implicit VARCHAR2 data that can potentially cause errors.
If you must serialize the resulting XMLType column and then use the methods getStringVal(), getClobVal(), or XMLSerialize (11g).

Dear all,
I have two tables
TABLE A (A_DATE, COLA1, COLA2)
TABLE B (B_DATE)
A_DATE = B_DATE
Examples of tables:
TABLE A (11 selected lines)
A_DATE COLA1 COLA2 03/01/2013 54 VAL76 04/01/2013 11 VAL78 04/01/2013 11 VAL22 04/01/2013 74 VAL22 04/02/2013 15 VAL45 04/02/2013 11 VAL22 04/03/2013 44 VAL22 04/03/2013 71 VAL73 04/04/2013 99 VAL13 04/05/2013 11 VAL22 04/05/2013 11 VAL23 TABLE B (01 April-30 April)
B_DATE 04/01/2013 04/02/2013 04/03/2013 04/04/2013 (condition 1: month: April)
AND
condition 2: CALA1-> 11
AND
condition 3: COLA2-> VAL22)
I need to display all records for the months April to TABLE A,.
If the documents are not present in TABLE A for every 30 days, I need to display null, by reading DATE information in TABLE B
Expected results (sample)
Date COLA1 COLA2 04/01/2013 11 VAL22 04/02/2013 11 VAL22 04/03/2013 04/04/2013 04/05/2013 11 VAL22 Currently I have the following query
Select A_DATE, COLA1, COLA2 from TABLEA
where COLA1 = 11 and COLA2 in ('VAL22') and A_DATE between ' 2013-04-01 00:00:00.0' AND ' 00:00:00.0' 2013-04-30

Select B_DATE, null, null from TABLEB if date between ' 2013 - 04 - 01 00:00:00.0' AND ' 00:00:00.0' 2013-04-30
But I'm the duplicate records for the values in TABLE a.
Output current (sample)

Hello
Try this:
Select b.B_DATE, a, COLA1, one, COLA2
from TABLEB b
the left join TABLEA a
On a.A_DATE = b.B_DATE
and COLA1 = 11
and COLA2 in ('VAL22')
where B_DATE between to_date('2013-04-01','yyyy-mm-dd') AND to_date('2013-04-30','yyyy-mm-dd')

Using XQuery with PL/SQL, link the Variable
I am only able to find an example of use of xquery with pl/sql.
[http://www.comp.dit.ie/btierney/oracle11gdoc/appdev.111/b28369/xdb_xquery.htm#CBAEEJDE]
Why is what they show only using bind variables? It's the only way it should be used, it provides a performance gain more simply by using the crossing clause and a passing beam a PL/SQL variable? I'm looking to implement a solution for my company using Xquery in PL/SQL. I am concerned that these procedures will be called during a flow of the user interface and performance it must be as soon as possible.A PL/SQL variable, column, or the output of another operation would be all be equivalent to a connection variable that PL/SQL compilation is concerned. Which would be bad practice would be to build in XQuery with the predicate hardcoded in the XQuery operation whenever the XQuery query has been run.

ODI 11 g multiple table with union join
Hi all
I have a problem with joining 4 different tables and union all of them.
Here I want to generate this query;
Select * from
Table1, table2
Join table2 = table1
Union of all the
Select * from
Table 3, table 4
Join table3 = table 4
But I have not the same column that all the table, some are missing. When I write one - PL/SQL query I can easily add a false "NULL column1' column, but I can not how I do with ODI 11 g.
I tried not to use "Active Mapping", but it does not work.
I'm newbie ODI 11 g
Thank you
Myra
Hi, Myra,.
I'd even as in PL/SQL. In your table target add all the columns you need and overall data whatever you're missing some columns just put NULL in the mapping.
Thank you

With the help of SCORE on top of view with UNION
Hi guys,.
I explain what I'm trying to do it quickly:
2 tables: table1 and table2 with the same structure and have both a multi_column_datastore ctxsys.context.
1 view: View1
Select * from table1
Union
Select * from table2
If I run:
Select * from View1 WHERE contains (view1. Column1, '% textext %', 1) > 0;
It works fine, I get the correct result.
If I try to use the PARTITION function, I got an error:
Select * from View1 WHERE contains (view1. Column1, '% textext %', 1) > 0 ORDER by SCORE (1);
ORA-29921: auxiliary operator not supported with query to configure block
I understand the problem is in the UNION inside the view, is it possible to keep work, filtering the VIEW?
Thanks in advance
There is no score in the view, so you cannot reference the score when you query the view. In order to put the note in the view, you need a contains the clause, which requires a value. A method to do this is to use sys_context. Please see the reproduction of the problem and solution below.

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.
Then, I use a cursor to execute it in a ftp file folder I selected passing ptype as a parameter.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'
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 cursorsThe 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 ; -

ConcerningHello
You are welcome.
I think that the best way to understand that is to show what data is generated at each stage...
1. we need to generate a list of lines that have every week, we are interested in swing on...
( SELECT to_number(to_char(sysdate,'IW')) + ROWNUM year_week_num FROM DUAL CONNECT BY LEVEL <= 5 ) row_gen YEAR_WEEK_NUM ------------- 30 31 32 33 342. must be added BACKLOG_WEEK_WH_AFTR_ATP lines in the calculations for the first week in the report
SELECT le.item_number, le.quantity, to_number(to_char(sysdate,'IW'))+1 year_week_num FROM BACKLOG_WEEK_WH_AFTR_ATP le UNION ALL SELECT re.item_number, -re.quantity, to_number(substr(re.year_week,-2,2)) year_week_num FROM BACKLOG_ATP_GT_CW_IN re / ITEM_NUMBE QUANTITY YEAR_WEEK_NUM ---------- ---------- ------------- ITEM_1 200 30 ITEM_2 600 30 ITEM_1 -200 30 ITEM_1 -100 33 ITEM_2 -300 30 ITEM_2 -200 32 ITEM_3 -800 30 ITEM_3 -400 343. we must now repeat weekly, generated by the request of row_gen against all of the item_numbers returned by the above query and match them if possible to get the amount. Where there is no entry in BACKLOG_WEEK_WH_AFTR_ATP or BACKLOG_ATP_GT_CW_IN for a number of the week, we should use 0 as the quantity. The Partition Outer Join does for us.
SQL> select 2 re.item_number, 3 row_gen.year_week_num, 4 NVL(re.quantity,0) qty 5 from 6 ( SELECT 7 to_number(to_char(sysdate,'IW')) + ROWNUM year_week_num 8 FROM 9 DUAL 10 CONNECT BY LEVEL <= 5 11 ) row_gen LEFT OUTER JOIN 12 ( SELECT 13 le.item_number, 14 le.quantity, 15 to_number(to_char(sysdate,'IW'))+1 year_week_num 16 FROM 17 BACKLOG_WEEK_WH_AFTR_ATP le 18 UNION ALL 19 SELECT 20 re.item_number, 21 -re.quantity, 22 to_number(substr(re.year_week,-2,2)) year_week_num 23 FROM 24 BACKLOG_ATP_GT_CW_IN re 25 ) re 26 PARTITION BY (re.item_number) 27 ON ( row_gen.year_week_num = re.year_week_num) 28 / ITEM_NUMBE YEAR_WEEK_NUM QTY ---------- ------------- ---------- ITEM_1 30 200 ITEM_1 30 -200 ITEM_1 31 0 ITEM_1 32 0 ITEM_1 33 -100 ITEM_1 34 0 ITEM_2 30 -300 ITEM_2 30 600 ITEM_2 31 0 ITEM_2 32 -200 ITEM_2 33 0 ITEM_2 34 0 ITEM_3 30 -800 ITEM_3 31 0 ITEM_3 32 0 ITEM_3 33 0 ITEM_3 34 -400 17 rows selected.4. now, we have the base dataset that we need - she has all the amounts with the right directions so that we can simply add everything up as a sum of sumulative. That's what makes OVER(PARTITION BY re.item_number ORDER BY row_gen.year_week_num) SUM (NVL(re.quantity,0)) bit. He said baseically are all lines seen so far in the result set for each item number...
select re.item_number, row_gen.year_week_num, NVL(re.quantity,0) qty, SUM(NVL(re.quantity,0)) OVER(PARTITION BY re.item_number ORDER BY row_gen.year_week_num) quantity from ( SELECT to_number(to_char(sysdate,'IW')) + ROWNUM year_week_num FROM DUAL CONNECT BY LEVEL <= 5 ) row_gen LEFT OUTER JOIN ( SELECT le.item_number, le.quantity, to_number(to_char(sysdate,'IW'))+1 year_week_num FROM BACKLOG_WEEK_WH_AFTR_ATP le UNION ALL SELECT re.item_number, -re.quantity, to_number(substr(re.year_week,-2,2)) year_week_num FROM BACKLOG_ATP_GT_CW_IN re ) re PARTITION BY (re.item_number) ON ( row_gen.year_week_num = re.year_week_num) / ITEM_NUMBE YEAR_WEEK_NUM QTY QUANTITY ---------- ------------- ---------- ---------- ITEM_1 30 200 0 ITEM_1 30 -200 0 ITEM_1 31 0 0 ITEM_1 32 0 0 ITEM_1 33 -100 -100 ITEM_1 34 0 -100 ITEM_2 30 -300 300 ITEM_2 30 600 300 ITEM_2 31 0 300 ITEM_2 32 -200 100 ITEM_2 33 0 100 ITEM_2 34 0 100 ITEM_3 30 -800 -800 ITEM_3 31 0 -800 ITEM_3 32 0 -800 ITEM_3 33 0 -800 ITEM_3 34 -400 -12005. we can now rotate these data in columns - however, there is a small problem. For points 1 and 2 we have 2 lines for the week 30, running in the quantity column total is the same for both because the two lines appear at the same point in the game as defined by the order by clause. This means before rotate us, we must select one of the lines - or the other will do, they are both correct. If we do not have, the effect will be to double the cumulative sum (for point 1 is 0, so it does not appear) for this, we can use the ROW_NUMBER function...
select re.item_number, row_gen.year_week_num, NVL(re.quantity,0) qty, SUM(NVL(re.quantity,0)) OVER(PARTITION BY re.item_number ORDER BY row_gen.year_week_num) quantity, ROW_NUMBER() OVER(PARTITION BY re.item_number, row_gen.year_week_num ORDER BY NULL) rn from ( SELECT to_number(to_char(sysdate,'IW')) + ROWNUM year_week_num FROM DUAL CONNECT BY LEVEL <= 5 ) row_gen LEFT OUTER JOIN ( SELECT le.item_number, le.quantity, to_number(to_char(sysdate,'IW'))+1 year_week_num FROM BACKLOG_WEEK_WH_AFTR_ATP le UNION ALL SELECT re.item_number, -re.quantity, to_number(substr(re.year_week,-2,2)) year_week_num FROM BACKLOG_ATP_GT_CW_IN re ) re PARTITION BY (re.item_number) ON ( row_gen.year_week_num = re.year_week_num) / ITEM_NUMBE YEAR_WEEK_NUM QTY QUANTITY RN ---------- ------------- ---------- ---------- ---------- ITEM_1 30 200 0 1 ITEM_1 30 -200 0 2 ITEM_1 31 0 0 1 ITEM_1 32 0 0 1 ITEM_1 33 -100 -100 1 ITEM_1 34 0 -100 1 ITEM_2 30 -300 300 1 ITEM_2 30 600 300 2 ITEM_2 31 0 300 1 ITEM_2 32 -200 100 1 ITEM_2 33 0 100 1 ITEM_2 34 0 100 1 ITEM_3 30 -800 -800 1 ITEM_3 31 0 -800 1 ITEM_3 32 0 -800 1 ITEM_3 33 0 -800 1 ITEM_3 34 -400 -1200 16. so now that we have a way to select one of the duplicate lines, we can move forward a pivot data by ensuring that us choose only 'first' line for each element for each week...
SELECT item_number, SUM ( CASE WHEN year_week_num = to_number(to_char(sysdate,'IW'))+1 THEN quantity END ) plus_1, SUM ( CASE WHEN year_week_num = to_number(to_char(sysdate,'IW'))+2 THEN quantity END ) plus_2, SUM ( CASE WHEN year_week_num = to_number(to_char(sysdate,'IW'))+3 THEN quantity END ) plus_3, SUM ( CASE WHEN year_week_num = to_number(to_char(sysdate,'IW'))+4 THEN quantity END ) plus_4, SUM ( CASE WHEN year_week_num = to_number(to_char(sysdate,'IW'))+5 THEN quantity END ) plus_5 FROM ( select re.item_number, row_gen.year_week_num, SUM(NVL(re.quantity,0)) OVER(PARTITION BY re.item_number ORDER BY row_gen.year_week_num) quantity, ROW_NUMBER() OVER(PARTITION BY re.item_number, row_gen.year_week_num ORDER BY NULL) rn from ( SELECT to_number(to_char(sysdate,'IW')) + ROWNUM year_week_num FROM DUAL CONNECT BY LEVEL <= 5 ) row_gen LEFT OUTER JOIN ( SELECT le.item_number, le.quantity, to_number(to_char(sysdate,'IW'))+1 year_week_num FROM BACKLOG_WEEK_WH_AFTR_ATP le UNION ALL SELECT re.item_number, -re.quantity, to_number(substr(re.year_week,-2,2)) year_week_num FROM BACKLOG_ATP_GT_CW_IN re ) re PARTITION BY (re.item_number) ON ( row_gen.year_week_num = re.year_week_num) ) WHERE rn = 1 GROUP BY item_numberYou need not add a join between BACKLOG_WEEK_WH_AFTR_ATP and BACKLOG_ATP_GT_CW_IN, because we are all summed up in the article number and all item numbers, we have selected two tables. The aggregation ensures that the quantities are added together against the item number.

List of values when using xquery with links?
Hello
What is the best way to build something like:
with XQuery variable when it is unclear how many entries will be in the listeType beforehand? I would like to somehow put ('a', 'b', 'c') in a context of query as a variable to something like:collection('test.dbxml')/tree[type=('a','b','c')]
So, avoiding the risk of strengthening of string concatenation queries.collection('test.dbxml')/tree[type=$var]Hello
Java example:
XmlResults res = manager.createResults(); res.add(new XmlValue("a")); res.add(new XmlValue("b")); res.add(new XmlValue("c")); .... xmlQueryContext.setVariableValue("myVarName", res);Vyacheslav

Report with the query with union and parameters
Hello
We have an obligation to create a report with the request, which is the union and parameters.
I intend to create a database for the report based on a query. But the problem here is that the way to pass parameters in the query.
Request is something like that
Select x.a, x.b, x.c
x
where x.year =: para1
and x.status = 'A '.
Union of all the
Select x.a, x.b, x.c
x
where x.year =: para1 - 1
and (x.status = 'c' and x.date =: para2 or x.status = 'I' and x.date < =: para2)
Here x.year in the first select statement must be equal to: para1 and second select statement, it should be: para - 1.
How this requirement can be achieved?
Client don't want to separate worksheet, a parameter and another for the actual data that I tried with sys_context and it worked. But the client wants the result in a single sheet only... So I need to change their approach.
Help, please.
Thank youHello
Another option is to convert the request so that you will have the items from the selection
for example on the query you provided that you can use:Select 'Curr' rec_type, x.a, x.b, x.c, x.year, x.date, x.status
x
where x.status = "A".
Union of all the
Select 'Prev' rec_type, x.a, x.b, x.c, x.year, x.date, x.status
x
where x.status in ('c', 'I')then, in the workbook, you will be able to create conditions such as:
rec_type = 'Curr' and year =: para1rec_type = 'Prev' and year =: para1-1
rec_type = 'Prev' and (status = 'c' and date =: para2 or status = 'I' and date)<=>Tamir

Hello Experts,
I'm still on the learning curve in PL/SQL and I have 2 different. I need to create a view that will merge these 2 tables.
I used the union of all, but it doesn't seem to work. I don't know where it's track. I searched on the net but his send me examples for 2 tables tat are similar.create view eft_view as select BILL_TO_RETAILER , RETAILER_NAME , NAME_ON_BANK_ACCOUNT , BANK_ABA , BANK_ACCT , ON_LINE_AMOUNT , INSTANT_AMOUNT , TOTAL_AMOUNT , SOURCE , INSERTED_DATE , CDC from weekly_eft_temp union all select BILL_TO_RETAILER , RETAILER_NAME , STATUS , ON_LINE_AMOUNT , INSTANT_AMOUNT , NON_SWEPT_AMT , TTYPE , EXCEPTION_REASON from weekly_bill_expt_temp;
Any suggestions pleaseYou must replicate the columns that do not exist fill them with NULL values.
Perhaps;
create view eft_view as select bill_to_retailer, retailer_name, name_on_bank_account, bank_aba, bank_acct, null status, on_line_amount, instant_amount, total_amount, source, inserted_date, cdc, cast (null as number) non_swept_amt, null ttype, null exception_reason from weekly_eft_temp union all select bill_to_retailer, retailer_name, null name_on_bank_account, null bank_aba, null bank_acct, status, on_line_amount, instant_amount, null total_amount, null source, null inserted_date, nul cdc, non_swept_amt, ttype, exception_reason from weekly_bill_expt_temp; -

Transformation of XQuery with filter
Hello
I'm trying to implement a specific transformation: I need an object to a key filter.
As input, I have this structure:
<STRUCTURE> <item> // multiplicy : * <MONTH> <INDICATOR /> <LETA/> </item> </OBJECT_1> <OBJECT_2> <item> // multiplicy : * <ORDER_NUMBER/> <ORDER_LINE_NUMBER/> <MONTH /> </item> </OBJECT_2> </STRUCTURE>
Here is an example:
<STRUCTURE> <OBJECT_1> <item> <MONTH>2013_M06</MONTH> <INDICATOR>ABC</INDICATOR> <LETA>2012-04-24</LETA> </item> <item> <MONTH>2013_M05</MONTH> <INDICATOR>DEF</INDICATOR> <LETA>2012-04-24</LETA> </item> </OBJECT_1> <OBJECT_2> <item> <MONTH>2013_M06</MONTH> <ORDER_NUMBER>11111</ORDER_NUMBER> <ORDER_LINE_NUMBER>1</ORDER_LINE_NUMBER> </item> <item> <MONTH>2013_M06</MONTH> <ORDER_NUMBER>11111</ORDER_NUMBER> <ORDER_LINE_NUMBER>2</ORDER_LINE_NUMBER> </item> <item> <MONTH>2013_M05</MONTH> <ORDER_NUMBER>22222</ORDER_NUMBER> <ORDER_LINE_NUMBER>1</ORDER_LINE_NUMBER> </item> </OBJECT_2> </STRUCTURE>
I need to have this result:
<targetStructure> <object1> <month>2013_M06</month> <indicator>ABC</indicator> <leta>2012-04-24</leta> <object2> <orderNumber>11111</orderNumber> <orderLineNumber>1</orderLineNumber> </object2> <object2> <orderNumber>11111</orderNumber> <orderLineNumber>2</orderLineNumber> </object2> </object1> <object1> <month>2013_M05</month> <indicator>DEF</indicator> <leta>2012-04-24</leta> <object2> <orderNumber>22222</orderNumber> <orderLineNumber>1</orderLineNumber> </object2> </object1> </object1> </targetStructure>
My transformation XQ is like this:
(:: pragma bea:global-element-parameter parameter="$STRUCTURE" element="ns1:STRUCTURE" location="xxx" ::) (:: pragma bea:global-element-return element="ns0:targetStructure" location="xxy" ::) declare namespace ns1 = "urn:aa"; declare namespace ns0 = "http://vvv.com"; declare namespace xf = "http://tempuri.org/cc/"; declare function xf:myTransformation($z_STRUCTURE1 as element(ns1:STRUCTURE)) as element(ns0:targetStructure) <targetStructure> { for $item in $z_STRUCTURE1/ns1:OBJECT_1/ns1:item return <object1> { for $MONTH in $item/ns1:MONTH return <month>{ data($MONTH) }</month> } { for $INDICATOR in $item/ns1:INDICATOR return <indicator>{ data($INDICATOR) }</indicator> } { for $LETA in $item/ns1:LETA return <month>{ data($LETA) }</month> } { for $item0 in $STRUCTURE/ns1:OBJECT_1/ns1:item return <object2> { for $ORDER_NUMBER in $item/ns1:ORDER_NUMBER return <orderNumber>{ data($ORDER_NUMBER) }</orderNumber> } { for $ORDER_LINE_NUMBER in $item/ns1:ORDER_LINE_NUMBER return <orderLineNumber>{ data($ORDER_LINE_NUMBER) }</orderLineNumber> } </object2> } } </targetStructure>As you can see, I had everyone in each object1 object2, while I only need the object2 when the MONTH is equal to the object1 one...
I tried to replace line 32, by
for $item0 in $STRUCTURE/ns1:OBJECT_1/ns1:item[ns1:month=$item/ns1:MONTH/text()]
... or some variations, but I've never had what I expected...
Any ideas?

show all columns with union all
Hi all
How can I view all (and not common) columns of the two tables when I use union all likeselect m_id, total, cat_id from scott.maintenance where prod_id = 1 union all select m_id, total, prod_id from scott.maintenance where prod_id = 4
m_Id, total, cat_id, prod_id
Thank you

m_Id, total, cat_id, prod_idThank you
JohnnyThere 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.
