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.

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.

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 -

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...

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

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.

UNION ALL and UNION performance issue

Hi All,
I am trying to figure out the data for which only receive transaction has been done and further processing is pending. These transactions include all PO, RMA , ISO etc...
I have to use UNION ALL in this case as for RMA and ISO, details which i want are not able to gather in a single query.
But query is taking a lot of time ...may be around 30..mins in UNION ALL while 6 to 7 mins in UNION.
To get all records I must have to use UNION ALL...
So kindly suggest the solution for this problem
Thanks

     )

In this case, for selected columns, all data is same for one of the RMA with more than one line. So UNION will skip one of the records. However, shipment line id are different for both records, so by selecting it in select list is solving the problem and so no need to use UNION ALL. But, anyhow UNION ALL is better than UNION in performance as it does not require to sort. Then why I am facing this problem...
Kindly suggest

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.

PS CS6: Images sometimes not saved when using Close All and instructed to save

I thought I had made a crazy mistake when this happened earlier today, but it just did it again and I was paying close attention.
I often open multiple images to make several changes, then use Close All and when it prompts "Do you want to save changes to ... before closing?" I check off the box to "Apply to all" and say Yes. This saves lots of time when adjusting several multi-hundred MB images. Imagine my surprise today when it closed an image without saving! I had to repeat about 30 minutes of work as a result.
I thought I had somehow accidentally clicked "No" to saving, so I made sure to pay close attention the next few times I used Close All to save work. It worked fine until a moment ago when it did it again.
Has anyone seen something like this? I can't find anything in searching. In all my time using this feature in PS I never once had a problem before.

Thanks for the reply.
I just upgraded to CS6 from CS5 a few days ago, and this is my first week in heavy usage.
I do have Save in Background turned on. I am saving locally. I also have auto recovery saves turned on, at 5 minute intervals (CS6 has crashed a few times on me)
Yesterday I used Close All with Save maybe 10 times, and it exhibited this behavior 2 of those times.
In the two cases, I had 3 PSDs open, each a little over 400 mb in size. It seemed to save two of the images, but left one unsaved. I noticed that instead of spending several seconds saving, it would quickly just close that image - as though it believed no changes had been made. The changes that had been made to the image were routine - add some adjustment layers, some masks etc.
I have tried to reproduce it by opening the same images, making similar changes and then repeating Close All with Save, but so far no (bad) luck. Idle speculation - could it have something to do with the frequent interval of autorecovery saves that I do? Some kind of conflict? Or is it something to do with background saves? Definitely never saw this in previous versions of PS.
As a workaround, I have made a simple action that saves an image and apply it in batch. I just can't risk losing work.

Inconsistent SQL results when using View with UNION-ALL and table function

Can any of you please execute the below scripts and check the output. In the table type variable, I am adding 4 distinct object ids, where as in the result, I get only the row pertaining to last id in the table type variable. Same row is returned 4 times (4= number of values in the table type).
This scenario is occurring in our product with a SQL with exactly same pattern. I could simulate the same issue with the sample script I have provided.

Text query using a Multi Column datastore index slow

I have created a text index using multi column datastore preference. I have specified two clob columns in my preference. Searching on this new index works, but it is slower than I expected.
I have done the following comparison:
My original two clob columns are: DocumentBody and DocumentFields. I have built an individual text index on each column. My new column with Multi Column index is DocumentBodyAndFields;
I did two queries:
1. search 'dog' on DocumentBody UNION search 'dog' on DocumentFields;
2. search 'dog' on DocumentBodyAndFields;
I would think the second search should be faster than the first one because it is a single query. But this is not the case. The second query is consistently slower than the first query by about 10-20%.
Things are getting much worse when I search on preceding wildcards. If I search '%job', the multi column index is twice as slow as the first query! I am very confused by this result. Is this a bug?

I am unable to reproduce the performance problem. In my tests, the search that uses the multicolumn_datastore performs better, as demonstrated below. Can you provide a similar test case that shows the table structure, datastore, index creations, and explain plan?

Command Query using UNION

Hello,
I may be barking up the wrong tree and asking this question in the wrong forum so please accept my apologies if this is the case.
I have access to a MYSql database through a ODBC connection and would like to create a report based on four tables (let's say A, B, C and D) where tables A & B hold biographical data and tables C & D contain different attribute detail with identical column names (attrib_name and attrib_desc) that relate to A & B .
The report I would like to create will list records from both A and B along with corresponding records from C and D merged into two columns attrib_name and attrib_desc.
I have tried a couple of versions of a union query but I just cannot seem to get it to generate the correct output.
Any help would be much appreciated.
Thank you
Paul

hi Paul,
Command objects are written in syntax specific to the database that you're using, so you may be best off looking at mysql forums instead. plus you haven't really stated what the issue is that you experiencing.
given the above, here's a couple basic things about UNION syntax...
1 the number of fields selected must be the same
2 the corresponding fields should be in the same sequence
3 the types (e.g. date, integer) must match
4 in your SELECT statement use an AS 'name' for each field so that the field names match up in both sets in the query
you may also wish to use a UNION ALL instead of a UNION as UNION ALL will ensure that all records are brought back as opposed to UNION which does a check on a virtual record set to ensure that there's no duplicates...this in turn can cause performance to suffer a bit.

Writing query using UNION Operator

Question -
(1)
Write an SQL Statement to list the following items: Customer ID, Customer Name, number of invoices, sum of total for invoices. Ensure that all customers are returned in the result set.
Answer for the above is written as below by one person. That seams to be correct. Is there another way of writing this same query.;
select c.CUSTOMER_ID,c.NAME,i.cnt,i.s
from gee_customer c,(select customer_id,count(*) as cnt, sum(TOTAL) as s
from gee_invoice
group by customer_id) i
where c.CUSTOMER_ID = i.customer_id (+)
(2)
My other question is How to write the above answer (or what you sugest) using UNION operator ?
Any ideas please

In fact the outer join means you use the union of two result sets - usual join result
and the rows from the outer table for which there is not any row in the inner table.

Sql query using union

hi
i need the query to fetch the data ...
i have two table
1. plan
2. voidplan
each table has id uniquely, and each table has rep_id but it is not unique.
i retrieved the data from both table using union. now i need the data for the rep who is in both table. i want to check union by id, and i need to retrieve the reps who is in both tables.
my code is
select "PLAN"."ID" as "ID",
     "PLAN"."REP_ID" as "REP_ID",
     "PLAN"."REGION" as "REGION",
     "PLAN"."LOB" as "LOB",
     "PLAN"."PLAN_HIERARCHY_CHANGE" as "PLAN_HIERARCHY_CHANGE"
from     "PLAN" "PLAN" ,"VOIDPLAN" "VOIDPLAN" where "PLAN"."REP_ID" IN (SELECT REP_ID FROM VOIDPLAN)
UNION
SELECT "VOIDPLAN"."ID" as "ID",
     "VOIDPLAN"."REP_ID" as "REP_ID",
     "VOIDPLAN"."REGION" as "REGION",
     "VOIDPLAN"."LOB" as "LOB",
     "VOIDPLAN"."PLAN_HIERARCHY_CHANGE" as "PLAN_HIERARCHY_CHANGE"
from     "VOIDPLAN" "VOIDPLAN"
THIS QUERY GIVES ALL UNION RESULT, NUT IT DOES'T FILTER THE REP_ID, IT SHOWS ALL THE REP_ID, I NEED THE REPS WHO IS IN BOTH TABLES
CAN ANYONE PLEASE TELL ME THE SOLUTION
