Cannot export query output when using UNION ALL

Hi
I can run a query in SQL Developer 1.5.5 and if it's a SELECT statement it works fine, but if I output the result of several SELECT statements using UNION ALL after some 10,000 records the SQL Developer crashes and it generates a file whose size is 0 kb
Is there a workaround for this??
Thanks and Regards!
Isaac

Should be fixed in the upcoming 2.1... you can try the RC1 also...

Drill down problem when using union all combination

Hi All,
I have a simple report with a drill down. The report has three columns Region, Sales, Flag... which will drill down to detail level of sales. The Flag column has Y, N values and we added 'All' Value in flag so that the user can select Y, N and All from the table prompt in the report . We have used union all in the report using combination to add the ' All ' Value in the flag. The problem is that now the main report is not passing the Flag values to the detail report. Flag is prompted in the filter in detail report.
If I remove the 'All' value from Analysis with only Y N selection criteria the drill down works.
Is there any work around? I have to use table prompt and All value selection in flag for drill down.
Thanks,
Virat

The problem is without union all when doing combination of analysis drill down works, when I use combination drill down does not work because it does not pass the parameters for flag . I have used union all to add All value in flag.

Need sql query to remove duplicates using UNION ALL clause

Hi,
I have a sql query which has UNION clause.But the UNION clause is causing some performance issues.
To overcome that I have used UNION ALL to improve performance but its returning duplicates.
Kindly anyone send a sample SQL query where my primary objective is used to use UNION ALL clause and to consider unique rows (elimating duplicate
ones)
Any help will be needful for me
Thanks and Regards

why not UNION? :(
another way also use MINUS

Why should we select all key fields when using for all entries

Hi,
Why should we select all key fields in our select query when using for all entries statement?
I read about for all entries but this point was not clear in any post.
Please explain me
Regards,
Subhashini

Dear Subhasini,
It is because FOR ALL ENTRIES deletes the duplicate entries before populating the target internal table.
Please do an F1 on FOR ALL ENTRIES & read the SAP documentation.
I mean how duplicate entries will not get deleted when we use this?
Quite simple, if you select all key fields then each entry will be unique & there will not be any duplicate entries to delete !!
BR,
Suhas

Performance using UNION ALL

Hello
i have 2 schemas S1 and S2 containing complex relational tables. The tables in each schema are related to each other via foreign key relationships. i made views for feature tables in both the schemas , querying column values from their related tables.
the data structure in both the schemas are exactly the same. Dut to management reasons we have to split them in 2 schemas. S1 contain data for region A and S2 contains data from region B. Now the client wants to see a combined data from region A & B.
we are planning to create another schema S3 and make views combining views from S1 and S2 in both schemas (V1 in S1 + V1 in S2) using UNION ALL.
Does UNION ALL will make use of the indexes we already built for parent tables in S1 and S2? Will there be a performance degradation using this approach? What can be the best approach? Our client needs to see real time data....
regards
sam

Since union does an extra sort it has a performance difference compared to union all.

In Mail, when using "reply all" why does Mail automatically include my email address in the cc line? Whey would I want to include my email address in an email I am sending.? Anybody have any idea how to stop Mail from including my email address in the cc line when using "reply all"?

Automatically cc myself is not checked. I did find out that if you have multiple email address that all of them need to be associated with "My Contact" tab. Thanks

When using FaceTime, all other sounds are muted. This defeats functionality. When will this be corrected?

When using FaceTime, all other sounds are muted. This defeats functionality. When will this be corrected? Does anyone know of a "fix" for this problem? This definately is NOT a feature.

yes, that is exactly what mine did too. I noticed that something is wrong after receiving calls and did not hear anything.
It was like the IPhone did not realize that the headphone is not any longer plugged in. I m not sure weather I plugged/unplugged the headphones after this more than once but it startet working correctly.

A patient is assigned an ednum. There are two different menus for staff to enter
diagnoses. Each menu stores the entries in a different table. The two tables are substance and pdiagnose. A patient’s diagnosis for a substance abuse can be entered in one table and not the other.
The number of entries for different substances for each patient can vary between the two tables. John Doe might be entered for alcohol and caffeine abuse in the pdiagnosis table and entered only for caffeine abuse in the substance table. They are only
linked by the ednum which has nothing to do with the diagnosis/substance. The substance entered in one table is not linked to the substance entered in the other. A query will not put an entry for alcohol from the pdiagnosis table on the same row as an alcohol
entry from the substance table except by chance. That is the reason for the way the query is written.
The query accepts parameters for a Dr ID and a start and end date. It takes about 7 to 15 seconds to run. Hard coding the dates cuts it down to about a second.
I might be able to select directly from the union all query instead of having it separate. But then I’m not sure about the order by clauses using aliases.
Is there a way to rewrite the query to speed it up?
I did not design the tables or come up with the process of entering diagnoses. It can’t be changed at this time.
Please let me know if you notice any inconsistencies between the DDLs, data, and output. I did a lot of editing.
Thanks for any suggestions.

Please post real DDL instead of your invented non-language, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions
and formatting rules. Your rude, non-SQL narrative is so far away from standards I cannot even use you as a bad example in book.
Temporal data should use ISO-8601 formats (we have to re-type the dialect you used!). Code should be in Standard SQL as much as possible and not local dialecT.
This is minimal polite behavior on SQL forums. You posted a total mess! Do you really have patients without names?? You really use a zero to fifty characters for a patient_nbr??? Give me an example. That is insane!
Your disaster has more NULLs than entire major corporate systems. Since you cannot change it, can you quit? I am serious. I have been employed in IT since 1965, and can see a meltdown.
I looked at this and I am not even going to try to help you; it is not worth it. I am sorry for you; you are in an environment where you cannot learn to do any right.
But you are still responsible for the rudeness of not posting DDL.

If so, then it does not "takes less than a sec to execute" but rather to fetch first screen of rows. When you use UNION Oracle has to return distinct rows from both queries. Therefore it must fetch not just first screen but all rows. To verify, issue first query and in yiour GUI tool click on get last screen. Then you'll know how long whole select takes. Do the same for second query. Also, do you need distinct rows or akll rows? IF all rows, change UNION to UNION ALL.

Select query-using Union All display duplicate records.

Hello All Gurus-
I am using Oracle 9.i
When i use the following query to fetch the records based on BUILDNUMBERNAME and ASSIGNED_BUILD then i am getting duplicate records -
select T1.ID FROM Defect T1,statedef T2,repoproject T3
WHERE T1.STATE=T2.ID AND T1.repoproject = T3.dbid AND T3.name Like 'ABC' AND T1. ASSIGNED_BUILD like '1.4.5.6'
Union All
select T1.ID FROM Defect T1,statedef T2,repoproject T3
WHERE T1.STATE=T2.ID AND T1.repoproject = T3.dbid AND T3.name Like 'ABC' AND T1.BUILDNUMBERNAME like '1.4.5.6'
How can i use the order by on T1.ID ? When i use the Order by T1.ID then it throws some error.
Kindly help me in this :(
Thanks in advance.

Sorry for not providing all of the details -
I am using Toad tool to run the query.
1-When i use the following query -
Select T1.ID FROM Defect T1,statedef T2,repoproject T3
WHERE T1.STATE=T2.ID AND T1.repoproject = T3.dbid AND T3.name Like 'ABC' AND T1. ASSIGNED_BUILD like '1.4.5.6' order by T1.ID
Union All
select T1.ID FROM Defect T1,statedef T2,repoproject T3
WHERE T1.STATE=T2.ID AND T1.repoproject = T3.dbid AND T3.name Like 'ABC' AND T1.BUILDNUMBERNAME like '1.4.5.6' order by T1.ID
ORA-00933: SQL command not properly ended.
2-If i am not using the T1.ID and run the following query
Select T1.ID FROM Defect T1,statedef T2,repoproject T3
WHERE T1.STATE=T2.ID AND T1.repoproject = T3.dbid AND T3.name Like 'ABC' AND T1. ASSIGNED_BUILD like '1.4.5.6'
Union All
select T1.ID FROM Defect T1,statedef T2,repoproject T3
WHERE T1.STATE=T2.ID AND T1.repoproject = T3.dbid AND T3.name Like 'ABC' AND T1.BUILDNUMBERNAME like '1.4.5.6'
Then it is running fine but it is displaying the duplicate values like -
00089646

00089148
00090118

OAF Export button fetching data in one column - view object using union all

Dear All,
Export button showing data in one column from view object,
View object is based on mulitple queries with union all ,
Please let me know the solution for this issue.
Thanks
Maheswara Raju

Maheswara Raju,
As per my understanding you are not able to export all the View Attribute using export Button. Only the attribute which is used with the item/region will get exported.
There are few work around in case if you want to export the column without showing on OAF Page. Let me know.
Cheers

Problem exporting to excel when using embedded web templates through WAD

Using web templates designed with WAD, we are experiencing an issue when trying to export excel when using embedded web templates.
We have set up tabstrips within our templates that load other templates (embedded into the global template).
Upon right clicking on any query and choosing "Export to Excel", any query that is in one of the tabs using the embedded web template item does not show up. Any queries in natively in the global web template will export and show up fine.
Any thoughts on how to enable something like this, or workarounds to make this work? We decided to split up these templates for performance reasons and can't go back from that decision. Also let me know if you need a better explanation of what we're trying to do.
Thanks in advance!
Jonathan

Hi SDBI,
Is this in place of loading a new template per tab? We are using container layouts in all of our templates so we can link things into tabstrips as well, we have just split up some templates to be embedded into tabs for performance reasons and data locking.
Also when exporting, we are looking for all of the items displayed at that time to be exported, however only the items from the global template show up, not all of the displayed queries. For example, anything outside of the tabstrip will export perfectly, but since the query embedded into the template the tabstrip is loading is not part of the native web template, it does not show up.
Seems like a tool limitation to me when embedding templates?
Thanks,
Jon

Using union all and rownum

Hello again.
Another question.
Can I query with union all and stop it when I get N rows.
For example:
select 1 from dba_segments
union all
select 2 from dba_segments where
union all
select 3 from dba_segments where;
and get the 100 first rows without doing the whole query:(not like that-->)
select * from (
select 1 from dba_segments
union all
select 2 from dba_segments where
union all
select 3 from dba_segments where)
where rownum < 100);
I want the query will stop when there are 100 rows in the result set.
thank you!

You already posted your own answer. It just seems you don't want to use it.
ROWNUM is NOT assigned until the rows are selected to be returned. So you need to wrap the three inner queries into a query that uses ROWNUM.

Can anyone tell me how to select extra row without using UNION or UNION ALL in pl/sql. Actually I want to have my o/p of query as partitioned by designation and ordered by salary and than one extra row which will contain the highest salary in a particular salary. My table has first_name,emp_id,designation and salary column. And I wnt the o/p as.
Mohinish,12212,SI,46000
Ram,11212,SSI,47000
Shyam,12133,SI,48000
Rick,9898,SI,46000
Rocky,12312,SSI,56000
Sariq,23948,SI,43000
Suman,12789,HR,49000
Sampy,12780,SI,46000
Parna,11111,HR,50000
Now the o/p should be.
Mohinish,12212,SI,46000
Rick,9898,SI,46000
Sariq,23948,SI,43000
Shyam,12133,SI,48000

Ram,11212,SSI,47000
Rocky,12312,SSI,56000
Rocky,12312,SSI,56000
Suman,12789,HR,49000
Parna,11111,HR,50000
Parna,11111,HR,50000
Thanks in Advance

You don't have to do a UNION or UNION ALL in PL/SQL but you would need to in SQL to get the desired output:
with data_recs
as (select 'Mohinish' first_name,12212 emp_id,'SI' designation,46000 salary from dual union
     select 'Ram',11212,'SSI',47000 from dual union
     select 'Shyam',12133,'SI',48000 from dual union
     select 'Rick',9898,'SI',46000 from dual union
     select 'Rocky',12312,'SSI',56000 from dual union
     select 'Sariq',23948,'SI',43000 from dual union
     select 'Suman',12789,'HR',49000 from dual union
     select 'Sampy',12780,'SI',46000 from dual union
     select 'Parna',11111,'HR',50000 from dual)
select first_name, emp_id, designation, salary from data_recs union all
select s.first_name, s.emp_id, s.designation, s.salary
from (select first_name,
               emp_id,
               designation,
               salary,
               row_number() over (partition by designation order by salary desc) high_salary
          from data_recs
         order by designation, salary) s
where s.high_salary = 1
order by designation, salary;
FIRST_NAME EMP_ID DESIGNATION   SALARY

Parna        11111 HR             50000
Sariq        23948 SI             43000
