Union All query help
Hi,
I have a union all query like this :
select a.prod_id,count(a.app_id) as noofapplications from enrollment a,attest b
where a.e_id=b.e_id group by a.prod_id
union all
select a.prod_id,count(a.app_id) as noofapplications from data_feed x,prod_feed y
where x.agent_num=y.prod_id group by y.prod_id
I get the results something like this :
prod_id noofapplications
x1824787 2
y397458 4
y397458 3
r457868 3
i876247 6
In below results y397458 is showing twice since it results from both the queries .But i want a single result like this :
prod_id noofapplications
x1824787 2
y397458 7
r457868 3
i876247 6
For y397458 it should add 4+3 and the result should be displayed one time only .
Please help ..
Thanks in Advance
Slightly reorder your query text:
select prod_id,count(app_id) as noofapplications
from
select a.prod_id,a.app_id
from enrollment a,attest b
where a.e_id=b.e_id
union all
select a.prod_id,a.app_id
from data_feed x,prod_feed y
where x.agent_num=y.prod_id
group by prod_id

Hi,
Is Order by in Union ALL query allowed? If not what is the solution while using Unoin ALL?
thxWhat isn't working? These are all OK:
SELECT dummy FROM dual
UNION ALL
SELECT dummy FROM dual
ORDER BY dummy;
SELECT dummy FROM dual
UNION ALL
SELECT dummy FROM dual
ORDER BY 1;
SELECT dummy AS c1 FROM dual
UNION ALL
SELECT dummy FROM dual
ORDER BY c1;The name used in the ORDER BY clause has to be one of the names in the first SELECT list, or a number. -
Hi all,
I want to fetch records from mview m_view1 joining the columns in table1 and table2.
select mv1.col1,mv2.col2.., from mview1 mv1
where mv1.col1 in (

WHERE t1.col2 = SUBSTR(user,3)
UNION ALL

Error while executing UNION ALL query
Hello everyone,
I'm executing the below query on Oracle 9.2.0.8 version.
select hdr.*
from ttl_hdr hdr, ttl_service ser
where hdr.cus_nbr = ser.cus_nbr
and hdr.dn in ('1232','2342',343','343')
union all
select hdr.*
from ttl_hdr_his hdr, ttl_service ser
where hdr.cus_nbr = ser.cus_nbr
and hdr.dn in ('1232','2342',343','343')
and I encounter following error:
ORA-01790: expression must have same datatype as corresponding expression
But instead of * if I'm specifying a list of few columns, it executes the query properly.
Can anybody tell me what the problem is ?
regards,
RossyHi,
All columns in your tables TTL_HDR and TTL_HDR_HIS are not with same data type.
I'm sure you get same error if you specify all columns that * brings.
Specify column names and use conversion function to get data type same to column from both selects.
PS: and I think this is not Application Express related
Br, Jari -
Is the order in which a UNION ALL query returns rows guaranteed?
Guys
I'm doing a kind of query where I want to return matching rows in a priority order and take the first one. THink of it as getting the most specific error message for a particular context.
SELECT * FROM (
SELECT msg FROM errormessages WHERE device = 'x'
UNION ALL
SELECT msg FROM errormessages WHERE client = 'y'
UNION ALL
SELECT msg FROM (SELECT msg from errormessages WHERE class LIKE 'generic_' ORDER BY class)
UNION ALL
SELECT 'missing error message' FROM dual
WHERE ROWNUM =1
If UNION ALL is guaranteed to return rows in this order, great. If not, would it be better to have:
SELECT * FROM ( SELECT * FROM(
SELECT 1 as ord, msg FROM errormessages WHERE device = 'x'
UNION ALL
SELECT 2, msg FROM errormessages WHERE client = 'y'
UNION ALL
SELECT 4+SUBSTR(class, 7, 1), msg FROM errormessages WHERE class LIKE 'generic_'
UNION ALL
SELECT 9999, 'missing error message' FROM dual
) ORDER BY ord )
WHERE ROWNUM =1Or, another option:
SELECT msg FROM(
SELECT
CASE
WHEN device = 'x' THEN 1
WHEN client = 'y' THEN 2
WHEN class LIKE 'generic_' THEN 4+SUBSTR(class, 7, 1)
END as ord, msg
FROM (
SELECT * FROM errormessages WHERE device = 'x' OR client = 'y' OR class LIKE 'generic_'
UNION ALL
SELECT 999, 'missing error' FROM dual
) ORDER BY ord
)WHERE ROWNUM =1As you can see there is a complication in the generic; devices may advertise that they accept 1,2,3 or 4 lines of info, so I want to use the advertised capabiltiy to pick the most relevant message from the generic set if no specifics exist for the device or the client
Which was would you go?
Cheers

So tell me guys, do I go for:

or
1 query with 4 ORs in the where clause and a case when to determine priority?It will depend on your conditions, but if you look at your explain plans you should get an idea for which is the better one; typically I would expect this to be the OR method...

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.

Learn how to follow ISO-11179 data element naming conventions

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.

Union All in a Subquery - Help
Hello All,
I am trying to create a Union All query but when i put a parameter in the where clause, i get an error. The Query is mentioned below:
SELECT T0.U_Srv_TechName, T0.ItemCode, T0.Dscription, SUM(T0.Quantity) AS [Bal Qty]
FROM (SELECT dbo.OWTR.U_Srv_TechName, dbo.WTR1.ItemCode, dbo.WTR1.Dscription, SUM(dbo.WTR1.Quantity) AS Quantity
FROM dbo.OWTR INNER JOIN
dbo.WTR1 ON dbo.OWTR.DocEntry = dbo.WTR1.DocEntry
GROUP BY dbo.OWTR.U_Srv_TechName, dbo.WTR1.ItemCode, dbo.WTR1.Dscription
UNION ALL
SELECT dbo.ODLN.U_Srv_TechName, dbo.DLN1.ItemCode, dbo.DLN1.Dscription, SUM(dbo.DLN1.Quantity * - 1) AS Quantity
FROM dbo.ODLN INNER JOIN
dbo.DLN1 ON dbo.ODLN.DocEntry = dbo.DLN1.DocEntry
GROUP BY dbo.ODLN.U_Srv_TechName, dbo.DLN1.ItemCode, dbo.DLN1.Dscription) T0
GROUP BY T0.U_Srv_TechName, T0.ItemCode, T0.Dscription
HAVING T0.U_Srv_TechName = [%0]
It gives me the error
1). [Microsoft][SQL Native Client][SQL Server]Must specify table to select from.
2). [Microsoft][SQL Native Client][SQL Server]Statement 'Service Contracts' (OCTR) (s) could not be prepared.
If I enter the name of the Technician (HAVING T0.U_Srv_TechName = 'xyz') it works fine. Also, if I execute the query in SQL Server with or without a prompt, it works fine. It's only on the SAP Query Manager that i'm having this problem. Please Help!
RezaReza,
Try this modification of the previous code, see if it works for you.
declare @stn varchar(20)
set @stn=/*SELECT T0.[DocNum] FROM OWTR T0 WHERE T0.[U_Srv_TechName] =*/'[%0]'
SELECT T0.U_Srv_TechName, T0.ItemCode, T0.Dscription, SUM(T0.Quantity) AS [Bal Qty]
FROM (SELECT T0.U_Srv_TechName, T1.ItemCode, T1.Dscription, SUM(T1.Quantity) AS Quantity
FROM OWTR T0 INNER JOIN
WTR1 T1 ON T0.DocEntry = T1.DocEntry
GROUP BY T0.U_Srv_TechName, T1.ItemCode, T1.Dscription
UNION ALL
SELECT T2.U_Srv_TechName, T3.ItemCode, T3.Dscription, SUM(T3.Quantity * - 1) AS Quantity
FROM ODLN T2 INNER JOIN
DLN1 T3 ON T2.DocEntry = T3.DocEntry
GROUP BY T2.U_Srv_TechName, T3.ItemCode, T3.Dscription) T0
GROUP BY T0.U_Srv_TechName, T0.ItemCode, T0.Dscription
HAVING T0.U_Srv_TechName =@stn
Hope this helps,

If i execute individually it works fine, if i use union all it throughs error for me.
Any suggestion...Hi,
In a set operation (such as UNION) table aliases (such as b.) only have meaning within the branch in which they are defined. The ORDER BY clause is not part of any 1 branch, so a table alias can't be used there.
In most cases, you can use a column name (or alias) from the first branch, like this:
SELECT b.audit_trail_id,
TO_CHAR (b.last_update_date, 'DD-Mon-YYYY') "Revision Date",
order by "Revision Date"
;and you can always order by column number, like this:
SELECT b.audit_trail_id,
TO_CHAR (b.last_update_date, 'DD-Mon-YYYY') "Revision Date",
order by 2
;In this case, however, there's an extra problem. You're transforming the DATE to a string in the SELECT clause. The string is all that's available in the ORDER BY clause, and the string '19-NOV-2012' comes after the string '01-JAN-2015', because the character '1' comes after '0'. Perhaps the simplest solution is to have your front end, and not the query, format the dates. In SQL*Plus, you can do this:
ALTER SESSION SET NLS_DATE_FORMAT = 'DD-MON-YYYY';
SELECT b.audit_trail_id,
b.last_update_date AS "Revision Date",
order by 2
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

UNION ALL destroys performance
Strangely, we have 2 queries, which when they run independently, run pretty fast (2 seconds for one, instantaneous for the other), but when they're concatenated into a UNION ALL query with no ORDER BY clause, it takes 45 seconds for it to run.
We tried pushing the SQL into a WITH clause, and some other subquery rewrites, but no perfomance boost. Has anyone seen this before?

Multiple UNION ALL views within a view returning incorrect records?
Hi,
I have a view which selects from multiple views with UNION ALL joining them. If I just select from the larg UNION ALL query I return more records (correct amount) than If I create a view, and select from it.
e.g.
SELECT *
FROM vw_load_1
UNION ALL
SELECT *
FROM vw_load_2
UNION ALL
SELECT *
FROM vw_load_3
UNION ALL
SELECT *
FROM vw_load_4
UNION ALL
SELECT *
FROM vw_load_5
Returns 405 Records
but
CREATE VIEW vw_master_load
AS
SELECT *
FROM vw_load_1
UNION ALL
SELECT *
FROM vw_load_2
UNION ALL
SELECT *
FROM vw_load_3
UNION ALL
SELECT *
FROM vw_load_4
UNION ALL
SELECT *
FROM vw_load_5;
SELECT COUNT(*)
FROM vw_master_load
Returns 307 records
Can anyone explain why, or how to get around this?
Oracle version: Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
PL/SQL Release 11.2.0.2.0 - ProductionHi,
Are you saying that you run:
select count(*) from (
SELECT *
FROM vw_load_1
UNION ALL
SELECT *
FROM vw_load_2
UNION ALL
SELECT *
FROM vw_load_3
UNION ALL
SELECT *
FROM vw_load_4
UNION ALL
SELECT *
FROM vw_load_5
result is: 307 And then you run
SELECT *
FROM vw_load_1
UNION ALL
SELECT *
FROM vw_load_2
UNION ALL
SELECT *
FROM vw_load_3
UNION ALL
SELECT *
FROM vw_load_4
UNION ALL
SELECT *
FROM vw_load_5
returns 405 rowsIf so, that is very strange.
Can you an example we can re-produce?
Regards,

Help required on UNION ALL for select query
Hello all,
The execution plan for an SQL is impacted when another SELECT is concatenated with a UNION ALL. The two SELECTS are very efficient when run separately (< 100 buffer gets), but when run together (using a UNION ALL), the execution plan changes (for the first SELECT) and the buffer gets jumps to over 45000!
what customer says with the UNION ALL, Oracle instead of doing a Merge Scan (that allows the inner table to filter out the rows from the outer table), chooses to do a NL join. This results in a Unique Index scan for each one of the 15000 rows in the outer table, resulting in 46000 consistent gets.
Can you please suggest customer why plan changes when they use UNION ALL & also suggest better way of running query.
Please refer to below explain plan .

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 Regardswhy not UNION? :(
another way also use MINUS
