Join in a query

Hello!
I'm neawby in SQL, and I have some problems with a query...
I have a table called "Artist" like this:
ART_ID     ART_NAME         ART_DESCRIPTION
1          Artist1          Desc1
2          Artist2          Desc2
3          Artist3          Desc3
4          Artist4          Desc4And another table called "Tour" like this:
TOUR_ID   TOUR_DATE          TOUR_ART_ID
1         10/10/2013         1
2         14/07/2014         4And definitively, I want to show something like this:
ART_ID     ART_NAME         ART_DESCRIPTION         TOUR_DATE
1          Artist1          Desc1                   10/10/2013
2          Artist2          Desc2
3          Artist3          Desc3
4          Artist4          Desc4                   14/07/2014If no tour_date for this artist, I want to show the artist too.
Thanks in advance!

Let me give you a hint to see if it will help you. Try it out, and if you cannot get it, come back and tell us what you tried
Hint: outer joins.
Edit: Blu ruined my nifty little idea :)Apologies John. I was in a kind mood as the OP at least bothered to display his data using {noformat}{noformat} tags so we could read it, and made it clear what he wanted, unlike some of the "I've got this... +unformatted data+ and I want this... +unformatted output+" questions we get. ;)

Restriction to Left Outer Joins in PS Query

Hello I am trying to do Left Outer JOin in PS QUERY. I need to do dept tbl, job code tbl and locatable as left outer joins with JOB Table. Looks like in PS QUERY there is a error message saying as below. Can someone has any workaround to achieve this in PS QUERY. I know I can create a View and use that in PS QUERY but BUsiness Users are dependent on IT, so that doesn't work. Also, adding JOB table multiple times works but I am looking for better solution if anyone had come accorss working through PS QUERY Outer JOins.
Windows Internet Explorer
Left outer joins must be joined to the last record in the query. (139,290)
OK
Thanks,

Joining with sub query not working

Hi
I am new with these complex queries. I am trying to join a sub query to a query as below;
SELECT Events1.InvoiceBatch AS BatchNo, Events1.InvoiceBatchDate AS BatchDate, tblClients.Company, tblClients.ID AS ClientID, COUNT(Events1.ID) AS Invoices,
COUNT(*) - COUNT(Events1.InvoicePrintDate) AS E, Events1.InvoiceBatchFromDate AS BatchFrom, Events1.InvoiceBatchToDate AS BatchTo, (SELECT EventID, SUM(Total) FROM tblStaffBookings AS StaffBookings WHERE StaffBookings.EventID = Events1.ID GROUP BY EventID) AS Total
FROM tblEvents AS Events1 LEFT OUTER JOIN
tblClients ON Events1.ClientID = tblClients.ID
WHERE (Events1.FactoringExportDate IS NULL) OR (Events1.AccountsExportDate IS NULL) OR (Events1.InvoiceSentDate IS NULL)
GROUP BY Events1.InvoiceBatch, Events1.InvoiceBatchDate, tblClients.Company, tblClients.ID, Events1.InvoiceBatchFromDate, Events1.InvoiceBatchToDate
HAVING (Events1.InvoiceBatch = 5212)
ORDER BY tblClients.Company
I am getting these two errors;
Msg 8120, Level 16, State 1, Line 2
Column 'tblEvents.ID' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
Msg 116, Level 16, State 1, Line 2
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.
What am I missing?
Thanks

Outer Join with the query

I have written the below query, our requirement is, Some employees have "Transport Allowance" but not "Project Allowance". For this, I tried to use OUTER JOIN with this query. But this query takes long time and failed. The following query works fine if the employee has both "Transport Allowance" and "Project Allowance" (without outer join) Now, I also need to retrieve the employees who have "Transport Allowance" but not "Project Allowance". How can I retrieve it?
SELECT DISTINCT papf.employee_number

Self join using ABAP Query

Hello all,
How to create a self join using ABAP Query?
Say, I have this table EKBE with belnr (materials doc num) and lfbnr (reference material doc num). I have to pick the PO's from EKBE whose belnr doesnt have any lfbnr.
Regards
Madhumathi A

hi madhu,
tables : ekbe.
data itab like standard table of ekbe with header line.
select * from ekbe into table itab where belnr >< 0 and lfbnr = ' '.
loop at itab.
write :/ itab-belnr,itab-lfbnr.
endloop.
check this code this works to select the orders whose belnr doesnt have any lfbnr

Hi! Everyone, I have some problems with JOIN and Sub-query; Could you help me, Please?

Dear Sir/Madam
I'm a student who is interested in Oracle Database and
I have some problems with JOIN and Sub-query.
I hope so many of you could help me.
if i use JOIN without sub-query, may it be faster or not?
SELECT field1, field2 FROM tableA INNER JOIN tableB
if i use JOIN with sub-query, may it be faster or not?
SELECT field1,field2,field3 FROM tableA INNER JOIN (SELECT field1,field2 FROM tableB)
Thanks in advance!

As the others have said, the execution plan will give you a better idea about which is faster.
If you're trying to see how using (or not using) a sub-query affects performance, make the rest of the queries as similar as possible. For example, include field3 in both queries, or ignore field3 in both queries.
In this particular case, I guess the optimizer would do the same thing either way, but that's just a guess. I can't see your execution plans.
In general, simpler code is faster, and better in other ways, too. In this case
tableB
is simpler than
(SELECT field1, field2 FROM tableB)
Why do you want a sub-query in this example?

Problem with JOINs in SELECT query

The parameter wa_dob-e_dob is not getting its definition ....
it contains DOB in current yr.
As i am using Joins also Workarea.... so is it coz Joins & WA cant be used simultaneously in a SELECT query....
Is there any other option to do the same...?

    CLEAR wa_data.
    CLEAR wa_dob.
    CLEAR l_temp_dob.
ENDLOOP.

Hi,
you are checking the work area in the SELECT. IN WHERE condition of the select u should specify fields in either of the tables pa0002 , pa0105 for data population.
The select is on the database table and not on the work area.for checking the data in the work area do this way:
loop at it_dob into wa_dob.
if wa_dob-e_dob between the range u want (w_sysdate AND w_edit_sysdate)
endif.
endloop.
ie: wa_dob-e_dob >w_sysdate AND wa_dob-e_dob < w_edit_sysdate or
    wa_dob-e_dob < w_sysdate AND wa_dob-e_dob > w_edit_sysdate
watever ur requirement is..

Why can't i use "INNER JOIN" in a query for SQL Server with JDBC??????

Hi,
I'm trying to execute some SQL queries and I just don't understand what's wrong.
I�m using Tomcat and SQL Server in order to do this, but when I�m try to execute a query with a INNER JOIN statements Tomcat raise a SQL exception... at the very first time I thought there was a problem with database connection but I realize that a simple query to a table works pretty well. then I found out some problems with JDBC:ODBC.... so I install JDBC for SQL Server 2000 and test with the same simple query and works..... so, I come to a conclusion.... INNER JOIN or JOIN statements can't be used in JDBC..... please... somebody tell I�m wrong and give me a hand...
I'm using TOMCAT 4 and JDK 1.4 SQL Server 2000
Error occurs when executeQuery() is called.... not prepareStatement().... ??????
Driver DriverRecResult = (Driver)Class.forName(driver).newInstance();
Connection ConnRecResult = DriverManager.getConnection(DSN,user,password);
PreparedStatement StatementRecResult = ConnRecResult.prepareStatement(query);
ResultSet RecResult = StatementRecResult.executeQuery(); <---- Exception raise here
So much tahnks in advance,

That's exactly what I think, driver it's raising the exception, but I don't know why.... i test the same query with INNER JOIN directly from SQL Query Analyser and it's works perfectly, my problem ain't SQL, but JSP and JDBC 'cause i'm a newbie about these issues.
Common sense tell me possible problems lie in SQLServer drivers 'cause i run the same pages on JRUN through jdbc:odbc and do works well, but by now i just depend on Tomcat.....
I've installed SQL Server drivers for JDBC but i just find it doesn't work fully... could be the version of JDK i've installed? what version do i need?
( I'm running Tomcat 4 with JDK 1.4 & SQL Server 2000 W2K )
thanks for reply.

How to use outer join on this query?

Hi all,
Hope doing well,
sir i am having one query which is here
SELECT C.* ,
P.Comp_Name Parent
FROM Comp_Master C
LEFT JOIN Comp_Master P
ON C.Parent_ID = P.Comp_ID
WHERE C.Comp_ID = 5;
and here is my table Comp_Master data like this:
Comp_ID Parent_ID Comp_Name
5 1 abc123
1 ROOT abc@123
after running this query with all column value in parent column abc@123 value should come. but it's not happening.
could u check this.
if any query please let me know.
Thanks

p.s. when I run your query against your data....
SQL> ed
Wrote file afiedt.buf
1 with comp_master as (select '5' comp_id, '1' parent_id, 'abc123' comp_name from dual union all
2                       select '1' comp_id, 'ROOT' parent_id, 'abc@123' comp_name from dual
3                      )

10       LEFT JOIN Comp_Master P ON C.Parent_ID = P.Comp_ID
11* WHERE C.Comp_ID = 5
SQL> /
C PARE COMP_NA PARENT
5 1    abc123 abc@123I get the output I expect from that query.
So what are you expecting?
I just ran the equivalent in SQL Server (I can't believe you got me to go and run that piece of rubbish... I haven't touched it in ages)...
with comp_master as (select '5' comp_id, '1' parent_id, 'abc123' comp_name union all
                     select '1' comp_id, 'ROOT' parent_id, 'abc@123' comp_name
SELECT C.*
      ,P.Comp_Name Parent
FROM Comp_Master C
     LEFT JOIN Comp_Master P ON C.Parent_ID = P.Comp_ID
WHERE C.Comp_ID = 5... and it gave me the same output.

Joins issue in query - OBIEE 11g

Hi all,
I have created a new repository with a simple star schema, and also have created ragged hierarchy. Now when i select any dimension field and a measure from the fact, the query generated by BI has 2 physical queries i.e. one for dimension and other for fact. but when it joins these 2 subqueries it does not consider any common column to join on , and results in incorrect data.
Not able to figure out what is going wrong. Pls. let me know hw to resolve this issue if any one has faced a similar one.

This query will pick the materials only if it is maintained across all the tables MARA,MARC,MVKE,AMPL,MBEW.
Now the requirement is, the program should pick the materials that are maintained in MARA table, doesn't matter if the material is not maintained in the other tables.
Please tell me how to modify this Select query. I dont have any idea on JOINs.
Thanks in Advance,
Neethu.

I am getting the error, "No fields from the right-hand table of a LEFT OUTER JOIN may appear in the WHERE condition:"B~WERKS".
Now prob. is with WHERE condition. If you know the solution please let me know.

Could anyone help me to avoid Cartesian join in this query?

Hi, guys:
Could you help me on this query? I must generate a Cartesian join, but I do not know why it happens. dt.debtorkey, cl.clientkey, inv.invoicekey, ag.agingkey are primary keys of each table. The problem is: I got same tuple for 8 times.
select dt.debtorkey, cl.clientkey, inv.invoicekey, ag.agingkey, dt.DebtorNo, dt.Name as "debtor Name", dt.State, cl.ClientNo, cl.Name as "Client Name", inv.InvNo, inv.PurchOrd, inv.Amt,
to_char(inv.InvDate, 'MM-DD-YY') invoice_date, to_char(ag.DateLastBuy, 'MM-DD-YY') aging_lastbuy, to_char(ag.DateLastPmt, 'MM-DD-YY') aging_lastpmt
from aging ag, invoices inv, debtors dt, clients cl
where ag.clientkey=cl.clientkey
and ag.debtorkey=dt.debtorkey
and inv.clientkey=cl.clientkey
and inv.debtorkey=dt.debtorkey
and ((inv.InvDate>=to_date(:P16_DP_IDF_START_DATE, 'MM/DD/YYYY')
and inv.InvDate<=to_date(:P16_DP_IDF_END_DATE, 'MM/DD/YYYY')
and ag.DateLastBuy=to_date(:P16_DP_IDF_LAST_BUY,'MM/DD/YYYY')
order by dt.name;Thanks a lot!

Hi,
Thanks for help. I am sorry for that I do not know how to upload a picture of explain plan. I am struggling to find how to provide sample data. I hope this data format could be at least useful.

No join in the query involving 2 tables

Friends,
I saw a strange plan for one query in TESTING DB today. Although 2 tables are involved i dont see any join , NL/HJ/SMJ !!
Can you please tell why this might be happening?
Note: i am not facing any performance issue but curious to know what type of optimization oracle is doing here.
It would be great if you could direct me the relevant link in the documentation.
Query text and plan :

FROM CAMPA.TABLE_A

          (SELECT NAME_ID
             FROM CAMPA.TABLE_B

With equality condition can i get NL/HJ join where the outer row source comes from the subquery?
What condition/pre-requisite of NL/HJ join is not met in this case?Don't use an equality condition with a subquery - this implicitly makes available to the CBO an optimisation strategy that can only be used if the subquery is guaranteed to return a single row.
So either use IN rather than = or use a JOIN not a SUBQUERY.
It's a bit of a strange question.
How do I remove this optimisation?
Take away the features that make that optimisation a possibility.
