Connect by complex query
Hi all,
I am working creating a hierarchy for a parent-child combination, but grouping by parent group field. I need to find a way to use more than one filter on the connect by clause.
This is the table that I have :
HIERID HIER VERID VER DIMPARENT DIMCHILD UNIT PARENTGROUP
541002 Hierachy01 529012 Version01 0 Hierachy01 0 0
541002 Hierachy01 529012 Version01 Hierachy01 Alternative Energy 0 1
541002 Hierachy01 529012 Version01 Alternative Energy Business 1 0 1
541002 Hierachy01 529012 Version01 Business 1 Australia 0 1
541002 Hierachy01 529012 Version01 Australia Region 1 1958 1
541002 Hierachy01 529012 Version01 Hierachy01 Alternative Energy 0 2
541002 Hierachy01 529012 Version01 Alternative Energy Business 1 0 2

541002 Hierachy01 529012 Version01 Canada Region 1 2014 4
I am running the following query, but is repiting the parent - child combination, because the same child could have multiple parents. Does any one has an idea how can I run my query?? I think I need to use the Parent group field on the connect by statement, but I don't know how to do it. Any idea will be gratefull.
Select distinct HIER as UnitHierarchy,
VER as Version,
DIMVALPARENT as ParentCode,
dimvalchild as ChildCode,
level AS HIERLEVEL,
SYS_CONNECT_BY_PATH(DIMVALCHILD, '/') as Path,
Unit as UnitID,
ParentGroup
from (Select distinct fk_HIERID,HIER,FK_VERID,VER,DIMVALPARENT,DIMVALCHILD,
UNIT,groupid as ParentGroup
from HierarchyMap
where HIER = 'Hierachy01' and ver = 'Version01' order by parentgroup,unit ) ---and (groupid='1'or groupid='0'))--
start with DIMVALPARENT = '0'
connect by prior DIMVALCHILD = DIMVALPARENT---- "can I use the one more field with the connect by??"
order by parentgroup,hierlevel
make sure you include 2 things in your queries.
# the row number
# the level
for traversing up the tree set
level = 0 - level and
row_number = 0 - row_number.
you than can then do an order by row_number if you union the two queries
for example:
============
select tbl.child,
tbl.parent,
level lvl,
rownum rn
from some_table tbl
start with tbl.parent = 4.1
connect by prior tbl.child = tbl.parent
union
select tbl.child,
tbl.parent,
0 - level lvl,
0 - rownum rn
from some_table tbl
start with tbl.child = 4.1
connect by prior tbl.parent = tbl.child
order by rn asc

Complex connect by prior query
I need SQL(for hierarchical tree) for a function which accepts node as input parameter and returns ref cursor.
Following is a sample tree:
1
--2.1
----3.1
------4.1
--------5.1
----------6.1
----------6.2
----3.2
------4.2
--------5.2
--2.2
----3.2
------4.2
--------5.2
----3.3
----3.4
------4.1
--------5.1
----------6.1
----------6.2
1 is at the root level and 2.1 & 2.2 are immediate children and so on.
The output tree should be all related parents and children of the passed node.
e.g:
If the input is 4.1, the output tree will be:
1
--2.1
----3.1
------4.1
--------5.1
----------6.1
----------6.2
--2.2
----3.4
------4.1
--------5.1
----------6.1
----------6.2
If the input is 4.2, the output tree will be:
1
--2.1
----3.2
------4.2
--------5.2
--2.2
----3.2
------4.2
--------5.2
The complex part, I guess, is to remove unwanted(not related) branches from the tree.
Following is the representation of the table RELATIONSHIP
ID PARENT CHILD
1-------1-------2.1
2-------1-------2.2
3-------2.1-----3.1
4-------2.1-----3.2
5-------2.2-----3.2
6-------2.2-----3.3
7-------2.2-----3.4
8-------3.1-----4.1
9-------3.2-----4.2
10------3.4-----4.1
11------4.1-----5.1
12------4.2-----5.2
13------5.1-----6.1
14------5.1-----6.2

Working with multiple results of a complex query
Hi all!
As I "advance" in learning PL/SQL with oracle, I now get stuck in handling multiple results of a complex query. As far as I know, I cannot use a cursor here, as there is no table where the cursor could point to.
Here is the concept of what I want to do (pseudocode):
foreach result in SELECT * FROM table_1, table_n WHERE key_1 = foreign_key_in_n;
-- do someting with the resultHere is my attemt, that freezes the browser gui and throws an internal database error:
declare
type t_stock is record(
baggage_id baggage.baggage_id%type,
section_id sections.section_id%type,
shelf_id shelves.shelf_id%type
v_stock t_stock;
rcnt number(2);
begin
dbms_output.put_line(TO_CHAR(rcnt));
loop
SELECT COUNT(*) INTO rcnt FROM (
SELECT baggage.baggage_id, sections.section_id, shelves.shelf_id
FROM baggage, sections, shelves
WHERE baggage.baggage_id = sections.contained_baggage_id
AND shelves.is_connex_to_section_id = sections.section_id);
IF rcnt <= 0 THEN
exit;
END IF;
SELECT baggage.baggage_id, sections.section_id, shelves.shelf_id INTO v_stock
FROM baggage, sections, shelves
WHERE baggage.baggage_id = sections.contained_baggage_id
AND shelves.is_connex_to_section_id = sections.section_id
AND ROWNUM < 2;
UPDATE sections SET contained_baggage_id = NULL WHERE section_id = v_stock.baggage_id;
commit; -- do I need that?
end loop;
END;
/So, is there a way to traverse a list of results from a complex query? Maybe without creating a temporary table (or is that the better way?).
regards, Alex
I reformatted the code
pktmOk, here are the details:
The tables are used to model kind of a transport system. There are terminals connected with sections that may contain 1 piece of baggage. The baggage is moved by a procedure through a transport system. After each of these "moving steps", I check if the baggage is in front of the shelf it should be in.
[To be honest, the give statement doesn't contain the info, in which shelf the baggage wil bee inserted. That was spared out because of the lack of a working piece of code :)]
But: if we consider the fact, that a baggage is in front of such a shelf in the way, that it should be put in this shelf, then all this makes some sense.
- move baggae through a transport system
- see if you can put baggage into a shelf
In order to "put baggage in a shelf", I need to remove it from the transport section. As the transport system is not normalized, I need to update the section where the baggage was in.
Uhm... yes it's a task that doesn't make too much sense. It seems to be some kind of general spirit in university homework :)
But: the FOR r IN (Statement) lloks good. I'll use that.
And, the ROWNUM < 2 is used to limit the size of the result to 1, there is no need to have a specific ordering. It's just because - afaik - oracle doesn't have a limit clause. I would appreciate your help if you know a better way to do limit resultsets.

Powershell use Connection String to query Database and write to Excel
Right now I have a powershell script that uses ODBC to query SQL Server 2008 / 2012 database and write to EXCEL
$excel = New-Object -Com Excel.Application
$excel.Visible = $True
$wb = $Excel.Workbooks.Add()
$ws = $wb.Worksheets.Item(1)
$ws.name = "GUP Download Activity"
$qt = $ws.QueryTables.Add("ODBC;DSN=$DSN;UID=$username;PWD=$password", $ws.Range("A1"), $SQL_Statement)
if ($qt.Refresh()){
$ws.Activate()
$ws.Select()
$excel.Rows.Item(1).HorizontalAlignment = $xlCenter
$excel.Rows.Item(1).VerticalAlignment = $xlTop
$excel.Rows.Item("1:1").Font.Name = "Calibri"
$excel.Rows.Item("1:1").Font.Size = 11
$excel.Rows.Item("1:1").Font.Bold = $true
$filename = "D:\Script\Reports\Status_$a.xlsx"
if (test-path $filename ) { rm $filename }
$wb.SaveAs($filename, $xlOpenXMLWorkbook) #save as an XML Workbook (xslx)
$wb.Saved = $True #flag it as being saved
$wb.Close() #close the document
$Excel.Quit() #and the instance of Excel
$wb = $Null #set all variables that point to Excel objects to null
$ws = $Null #makes sure Excel deflates
$Excel=$Null #let the air out
I would like to use connection string to query the database and write results to EXCEL, i.e.
$SQL_Statement = "SELECT ..."
$conn = New-Object System.Data.SqlClient.SqlConnection
$conn.ConnectionString = "Server=10.10.10.10;Initial Catalog=mydatabase;User Id=$username;Password=$password;"
$conn.Open()
$cmd = New-Object System.Data.SqlClient.SqlCommand($SQL_Statement,$conn)
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output += ,@($rdr.GetValue(0), $rdr.GetValue(1))
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
How would I read the columns and data for $sql_output into an EXCEL worksheet. Where do I find these tutorials?Hi Q.P.Waverly,
If you mean to export the data in $sql_output to excel document, please try to format the output with psobject:
$sql_output=@()
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output+=New-Object PSObject -Property @{data1 = $rdr.GetValue(0);data2 =$rdr.GetValue(1)}
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
Then please try to use the cmdlet "Export-Csv" to export the data to excel like:
$sql_output | Export-Csv d:\data.csv
Or you can export to worksheet like:
$excel = New-Object -ComObject Excel.Application
$excel.Visible = $true
$workbook = $excel.Workbooks.Add()
$sheet = $workbook.ActiveSheet
$counter = 0
$sql_output | ForEach-Object {
$counter++
$sheet.cells.Item($counter,1) = $_.data1$sheet.cells.Item($counter,2) = $_.data2}
Refer to:
PowerShell and Excel: Fast, Safe, and Reliable
If there is anything else regarding this issue, please feel free to post back.

OFFICE 2013 - Word could not re-establish a DDE connection to Microsoft Query
Hi, I have installed office 2013 on a pc and used excel to run a query on a database and created a .qry query so I can use this data in word mail merge.
The query runs ok and returns the data.
However, when I go to take the data in through mail merge it comes up with a message "Confirm data source" ( I enabled this after reading kb article below) so I select "MS query files via DDE(*.qry, *.dqy)" as this is a .dqy I select
it. It says at the bottom of the screen word is starting query then comes up with the error "Word could not re-establish a DDE connection to Microsoft Query to complete the current task".
I have re-did the query from scratch and no difference I tried the recommend kb article 918594 and it still doesn't work.
I recreated the odbc link and still no joy.
Has anyone come across this and have they a solution I would be grateful.
Thanks

1. How to create an explain plan with rowsource statistics for a complex query that include multiple table joins ?
When multiple tables are involved , and the actual number of rows returned is more than what the explain plan tells. How can I find out what change is needed in the stat plan ?
2. Does rowsource statistics gives some kind of understanding of Extended stats ?You can get Row Source Statistics only *after* the SQL has been executed. An Explain Plan midway cannot give you row source statistics.
To get row source statistics either set STATISTICS_LEVEL='ALL' in the session that executes theSQL OR use the Hint "gather_plan_statistics" in the SQL being executed.
Then use dbms_xplan.display_cursor

I am novice in PL/Sql. I need some help in writing a complex query.
I imagine the following table structure.
Type(string) Date(date) count(int)
Given a date range
The query needs to group the records on type and return the record (type and count) which has the max date (its just date, no time is involved) for each group (which is based on type) . If there are more than one records which have the max date then the average count should be returned for that type
i would be glad if someone could give any ideas as to how to go about this query. Thanking you in advance.
regards.Heres the query ... Forget the period .... wht this query is supposed to do is group on assigned ki for a given date range. then it has to get the value which is for the last record for that Ki in the date range. If there are 2 records which have max date then it should give an average.
e.g
assignedKI / date / value
a 1st may 2008 10
b 2nd may 2008 12
c 1st may 2008 13
a 30 - apr-2008 16
b 4th may 2008 17
a 1st may 2008 20
The query should return
a 1st may 2008 15 (which is the average as there are 2 values for the max date for a)
b 4th may 2008 17
c 1st may 2008 13
the following query doesnot work ....
SELECT
kiv2.assigned_k_i,
kiv2.ki_name,
kiv.period,
max( kiv2.ki_value_date) ,
avg(kiv2.ki_value)
FROM

iI guess I should use DBMS_SQL.BIND_VARIABLE to bind all variables seperately so not to mess with query1) What is the error you get?
2) If you use bind variables inside a query, you should prefix them with colons, so use :l_cur_year_from etc.
3) Why are you using dbms_sql instead of native dynamic sql and/or ref-cursors?

Trying to form complex query - need help
I have a fairly complex query that I need to join the results of to show actual and goal by day. The actuals are an aggregation of records that get put in every day, while the targets are a single entry in range format indicating an active range for which the target applies. I'm working on a query that will put things together by month and I'm running into a snag. Can someone please point out where appropriate naming needs to go to get this to come together?
This one works:

ELSE SUM(w.SPOT_WEIGHT)
END as WT
from TC c, TC_LOAD_JOBS j, LOAD_RATES r, SPOT_WEIGHTS w
where c.TC_ID = j.TC_ID and j.LOAD_RATE_ID = r.LOAD_RATE_ID
and c.DATE_INDEX = w.DATE_INDEX and j.LOAD_RATE_ID = w.LOAD_RATE_ID

and c.DATE_INDEX between to_date('08/01/2010','MM/DD/YYYY') and to_date('07/31/2011','MM/DD/YYYY')
group by c.DATE_INDEX, c.VEH_LOC
union

group by c.DATE_INDEX, c.VEH_LOC)
group by DATE_INDEX, VEH_LOC)

select (u.MACH_TPH_D+u.MACH_TPH_N)/2 as MTPH_TGT, (u.LABOR_TPH_D+u.LABOR_TPH_N)/2 as LTPH_TGT
from UTIL_TARGET_LOADERS u
where u.ORG_ID in (select ORG_ID from ORG_ENTITIES where MNG_ORG_ID = 200)The join needs to be based on VEH_LOC and DAY in the form:
... WHERE u.ORG_ID = x.VEH_LOC
AND x.DATE_INDEX between u.START_DATE and NVL(u.END_DATE,sysdate)I had one that worked just fine when only one entity was involved; the complication arises in that this is a division-level report so I have to individually resolve the subordinates and their goals before I can aggregate. This is one of two queries I need to tie together using a WITH clause so I can pivot the whole thing and present it in month-by-month fashion. When I try to tie it together like the query below, I get: invalid relational operator.
select ttls.DATE_INDEX, SUM(ttls.LDS) as TTLLDS, SUM(ttls.TONS) as TTLTONS, u.TARGET_LTPH, u.TARGET_MTPH

where ttls.DATE_INDEX beween u.START_DATE and NVL(u.END_DATE,sysdate)
and ttls.VEH_LOC = u.ORG_ID
group by ttls.DATE_INDEXI know this is a nested mess, as it has to grab the production from two tables for a range of VEH_LOC values and sum and aggregate by day and VEH_LOC, then I have to try and match that to the targets based on VEH_LOC and day. My final query is to aggregate the whole mess of sums and averages by month.
I'd appreciate it if someone can point me in the right direction.Figured it out.

Complex Query in toplink descriptor
I have a complex query with "Order by" and "Max" aggregation function and I am trying to convert it to a named query. I am using toplink descriptor in Jdeveloper 11G.
1. Is it possible to write a named query which returns values from more than two different table?
2. how to specify Max operation in the Toplink descriptor.
Here is my Query
select * from table1 t1 ,table2 t2
where
t1.id = t2.id and
t1.name ='Name' and
t1.status<>'DELETE' and
t2.a_id = (select max(a_id) from table2 t21 where
t21.a_id = t1.id and
group by id)TopLink supports sub-selects through sub-queries in TopLink Expressions, and through JPQL. I'm not sure on the JDev support though, you may need to use a code customizer or amendment to add the named query.

Issue with the below query. The query is not getting filtered for the condition hier_typ_c in('BS') with the connect by prior
query. query is fetching all the hier_type_c in the table like 'BS', 'CO', 'EC' etc....
Just wondering how do i restrict the query just to fetch the type_c ='BS' alone? why is it giving all the records??
Select
Level as LEVEL_CODE,
h.HIER_PRNT_NODE_I as PARENT,
h.HIER_CHLD_NODE_I as CHILD,
h.HIER_CHLD_NODE_X || ' (' || h.HIER_CHLD_NODE_I || ')' as ALIAS
From (Select Distinct HIER_CHLD_NODE_I, HIER_PRNT_NODE_I,
HIER_CHLD_NODE_X from .HIER_DIMN
where hier_typ_c in('BS') and CURR_VER_C = 'Y') h
Start with h.HIER_PRNT_NODE_I = 'ROOT'
Connect by prior
h.HIER_CHLD_NODE_I = h.HIER_PRNT_NODE_I
Order by LEVEL_CODE, parent, childHi
It loks like you're doing it right.
By basing the CONNECT BY query on a sub-query that has this WHERE clasue:
where hier_typ_c in('BS') and CURR_VER_C = 'Y') hyou should exclude not only nodes whose hier_typ_c is not 'BS', but also their descendants.
Post some sample data (CREATE TABLE and INSERT statements) and the results you want from that data.
Are you sure the query you posted is what you're actually running?
I would expect the sub-query FROM clause to cause an error because of the '.'.

Regards,
BMPFirst thing that i notice in this query is you are Using Distinct as well as Group by.
Your group by will always give you distinct results ,then again why do you need the Distinct?
For example
WITH t AS
(SELECT 'clm1' col1, 'contract1' col2,10 value
FROM DUAL
UNION ALL
SELECT 'clm1' , 'contract1' ,10 value
FROM DUAL
UNION ALL
SELECT 'clm1', 'contract2',10
FROM DUAL
UNION ALL
SELECT 'clm2', 'contract1',10
FROM DUAL
UNION ALL
SELECT 'clm3', 'contract1',10
FROM DUAL
UNION ALL
SELECT 'clm4', 'contract2',10
FROM DUAL)
SELECT distinct col1,col2,sum(value) from t
group by col1,col2Is always same as
WITH t AS
(SELECT 'clm1' col1, 'contract1' col2,10 value
FROM DUAL
UNION ALL
SELECT 'clm1' , 'contract1' ,10 value
FROM DUAL
UNION ALL
SELECT 'clm1', 'contract2',10
FROM DUAL
UNION ALL
SELECT 'clm2', 'contract1',10
FROM DUAL
UNION ALL
SELECT 'clm3', 'contract1',10
FROM DUAL
UNION ALL
SELECT 'clm4', 'contract2',10
FROM DUAL)
SELECT col1,col2,sum(value) from t
group by col1,col2And also
AND SOL.STATUS_DATE BETWEEN '01-JUN-09' AND '30-JUN-09'It would be best to use a to_date when hard coding your dates.

How to store data from a complex query and only fresh hourly or daily?
We have a report which runs quite slow (1-2 minutes) because the query is quite complicate, so we would like to run this query daily only and store in a table so for those procedures that need to use this complex query as a subquery, can just join to this table directly to get results.
However, I am not sure what kind of object I should use to store data for this complex query. Is data in global temp table only persist within transaction? I need something that can persist the data and be access by procedures.
Any suggestions are welcome,
CheersThank you for your reply. I looked at the materialized view earlier on, but have some difficulties to use it. So I have some questions here:
1.The complex query is not a sum or aggregate functions, it just need to get data from different tables based on different conditions, in this case is it still appropriate to use meterialized view?
2.If it is, I created one, but how to use it in my procedure? From the articles I read, it seems I can't just query from this view directly. So do I need to keep the complex query in my procedure and how the procedure will use the meterialized view instead?
3. I also put the complex query in a normal view, then create a materialized view for this normal view (I expect the data from the complex query will be cache here), then in the procedure I just select * from my_NormalView, but it takes the same time to run even when I set the QUERY_REWRITE_ENABLED to true in the alter session. So I am not sure what else I need to do to make sure the procedure use the materialized view instead of the normal view. Can I query from the Materialized View directly?
Below in the code I copied from one of the article to create the materialized view based on my normal view:
CREATE MATERIALIZED VIEW HK3ControlDB.MW_RIRating
PCTFREE 5 PCTUSED 60
TABLESPACE "USERS"
STORAGE (INITIAL 50K NEXT 50K)
USING INDEX STORAGE (INITIAL 25K NEXT 25K)
REFRESH START WITH ROUND(SYSDATE + 1) + 11/24
NEXT NEXT_DAY(TRUNC(SYSDATE), 'MONDAY') + 15/24
enable query rewrite
AS SELECT * FROM HK3ControlDB.VW_RIRating;

Strange Behaviour of Connect By Prior query
Has anybody faced a problem like your query returns alternative record like suppose you have 10 records in a table and your connect by prior query gives you 1st, 3rd, 5th and so on. My query was working fine few days back but suddenly its giving me different result. I don't know whether there was some settings changed by someone or not.
Can't guess anything from here. You need to post the query, sample data and the result.
