Key value pair relational table - cross tab / pivot out?
I have a Table of KVP and the structure is ID, Key, Value and this is the sample values...Table with values
ID, Key, Value
TABLE 1, TRUE
1, AGE GROUP, 10
1, TRAVEL, Y
2, TABLE, FALSE
2, AGE GROUP, 20
2, TRAVEL, N
I want to turn it these date like below (output)
ID, STATUS, AGE GROUP, TRAVEL
1, TRUE, 10, Y
2, FALSE, 20 N
I read on analysis crossroads/pivot - but not able to make a query that can give me the output above. The structure of the table cannot be changed...! My bad.
Is it possible in sql, to do my output to look like above?
It is possible if you know all the possible values for the KEY:
with t as (
select 1 id,'STATUS' key,'TRUE' val from dual union all
select 1,'AGE GROUP','10' from dual union all
select 1,'TRAVEL','Y' from dual union all
select 2,'STATUS','FALSE' from dual union all
select 2,'AGE GROUP','20' from dual union all
select 2,'TRAVEL','N' from dual
)
select id,
max(case key when 'STATUS' then val end) status,
max(case key when 'AGE' then val end) age,
max(case key when 'AGE GROUP' then val end) "AGE GROUP",
max(case key when 'TRAVEL' then val end) travel
from t
group by id
/
ID STATUS AGE AGE GROUP TRAVEL
---------- ------ ----- --------- ------
1 TRUE 10 Y
2 FALSE 20 N
SQL>
If you are on 11g, you can use the PIVOT, but again, he must know the columns resulting from the outset.
Another thing, you could do is to return a list CSV key of all the values in a column using STRAGG (or LISTAGG if you are on 11.2), hierarchical queries, XML or WM_CONCAT without papers.

Don't forget to call with several key-value pairs
I'm looking to invoke the application Remember and I try to send a title and a due date. The problem is that I don't know the format for sending multiple data items. Can someone help me with the format what should I use to having an remember entry created with a title and a due date?

How to programmatically Exchange data (key-value pairs) with operating system called?
Hi all
Is there a programmatic way to Exchange data (of the key-value pairs) with the guest OS?
We have an application that runs inside comments, and we want that this application in order to use this mechanism to Exchange data. At this point, the guest have no network connectivity. One thing that might work for us is to use the registry to the guest operating system. But I'm not sure how to handle the registry of the guest operating system.
We looked in the VirtualMachineConfigInfo.extraConfig property, but these key-value pairs are not accessible from the comments (at least this is what I know)
any ideas?
Thank you
Onur
I think that it is better to use an environment variable or file to Exchange data with the guest operating system.

To access the inside loops key/value pairs
According to the docs of Shopify, liquid allows access to key/value pairs in
{% for item in hash %} {{point [0]}}: {{point [1]}} {% endfor %}forloops, as follows:This does not work in the liquid renderer in British Colombia; the output of the key/value tags are empty. Here is an example of using the always available
{ ... {"urlculture": {"ModuleName": "urlculture", "culture": "EN"},...}this.urlcultureglobal object:{% for obj in this.urlculture %}
{{ obj | json }}Key: {{obj [0]}}
Value: {{obj [1]}}
{% endfor %}This is the result I get:
{ "Key": "moduleName", "Value": "urlculture" } Key: Value: { "Key": "culture", "Value": "EN" } Key: Value:Access by name (such as
{{ obj.Key }}) also fails.Am I missing something, or is this all just not yet implemented?
Also, why isn't the nice formatting illustrated in this visible post editor in the current post code?
Thank you, Robert.
This was a great find. And you'll be happy to learn that we have set and it will work in the next version (unfortunately the hotfix does not update today, we have deployed on the beta version).
You will then be able to do things like:
{% for getParam in globals.get %} {{getParam[0]}} = '{{getParam[1]}}'
{% endfor %}-Lucian

What is the best way to move with esx3.5 vmtools key/value pairs?
Hello
I found both candidates to store the key/value pairs for a vmware client. My ultimate goal is to run a process on the VC box that updates these data, and then read through the software tools of vm on the host (somehow) were invited.
The first method is through 'guestinfo' settings which can be adjusted in four ways:
Add the variable of the vmx fileprompt.
Set the variable manually on the client (using vmwareservice.exe - cmd "infoset");
using vmware-cmd (vmware-cmd & lt; vm-cfg-path & gt; setguestinfo & lt; variable & gt; & lt; value & gt;)
the use of vmcom.dll COM objects (seems to be deprecated in ESX 3.5)
These variables are easily accessible on the client by running vmwareservice.exe - cmd 'info-get guestinfo.variablename '. However, I cannot find a convenient way (better based on powershell) of their definition of a scheduled task or service to VC area.The second method is the customfields of guests in VItoolkit property, which can be defined as follows:
get - vm MyVMName | Game-CustomField-nameOfValue name-value DataToBeStored
Unfortunately, I am unable to access these data in the comments, and indeed I do not know if this is possible. If this isn't the case, I guess my only recourse would be to write a tool to connect to Web services on the VC box with a low privilege account. I prefer not to do this because it means the network infrastructure implementation to point the guest to the right VC, development of custom etc permissions...So, my questions are:
Is it possible to define variables of guestinfo through VI Toolbox, running on the virtual circuit?
Is it possible to read customfields on the client, through the vmtools?
Or is there another method to make this key/value data exchange?
You can add/edit entries in the VMX file like this
$vm = get-vm
| Get-View $vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec $vmConfigSpec.extraconfig += New-Object VMware.Vim.optionvalue $vmConfigSpec.extraconfig[0].Key= "guestinfo" $vmConfigSpec.extraconfig[0].Value = "whatever" $vm.ReconfigVM($vmConfigSpec) -
Hi Experts,
I have a DB table has columns of more than 50.
I question this table, it should only return one line at any time. as sqldeveloper below image.
here, I need to build block pl/sql-query, Discover the column in the table as a key and query result as values.
Eg: Key - Value
TASK_EVENT_ID - 1765
EVENT_TYPE - ASR_UPDATE
... etc until all of the columns in my table.
Experts please comment on that point, appreciate your help on this.

Add key/value pairs to an ArrayList from a HashMap in
I'm trying to create a HashMap, loop through this hash table, and finally, I try to create an ArrayList of key/value - of the HashMap pairs - containing, in its set of value, a parameter value. I know that maybe it's a little difficult to understand, so I provided my code to make sense what I'm trying to accomplish.
For the desired output, it can be assumed that the value of the productAttribute parameter is "computer."package data; import java.util.ArrayList; import java.util.HashMap; import java.util.Iterator; import java.util.Map; public class ProductInventory { private Map <String, ArrayList<String>> product; private ArrayList <String> buildProduct; private ArrayList <ArrayList<String>> addProduct; public ProductInventory() { /** Set default values **/ product = new <String, ArrayList<String>> HashMap(); buildProduct = new ArrayList<String> (); addProduct = new ArrayList<ArrayList <String>> (); /** START - Create ArrayList for each item and add to HashMap**/ ArrayList <String> c1 = new ArrayList<String>(); ArrayList <String> c2 = new ArrayList<String>(); c1.add("computer"); c1.add("Apple"); c1.add("iPad2"); c1.add("499.00"); c2.add("computer"); c2.add("Asus"); c2.add("Zenbook"); c2.add("1449.00"); ArrayList <String> tv1 = new ArrayList<String>(); ArrayList <String> tv2 = new ArrayList<String>(); tv1.add("television"); tv1.add("Panasonic"); tv1.add("Viera"); tv1.add("899.00"); tv2.add("television"); tv2.add("Samsung"); tv2.add("Series 6"); tv2.add("1597.00"); ArrayList <String> a1 = new ArrayList<String>(); ArrayList <String> a2 = new ArrayList<String>(); a1.add("audio"); a1.add("Bose"); a1.add("321 GS Series III"); a1.add("999.00"); a2.add("audio"); a2.add("Onkyo"); a2.add("HT-S3400"); a2.add("329.00"); /** END - Create ArrayList for each item and add to HashMap **/ /** Add entrys to HashMap **/ product.put("CMC769LLA",c1); product.put("CUX31EDH72",c2); product.put("TVTCL50E3",tv1); product.put("TVUN55D6000",tv2); product.put("A321GSIIIBK",a1); product.put("AHTS3400",a2); } /** For the sake of this example, the productAttribute parameter will be equal to "computer" **/ public void setProducts(String productAttribute) { for (Map.Entry <String, ArrayList<String>> entry : product.entrySet()) /** Loop through all entrys in the HashMap **/ { for (String s: entry.getValue()) /** Loop through all values in HashMap**/ { /** Add product attributes **/ if (s.equals(productAttribute)) /** Check to see if param exists in the value set**/ { /** Add key to buildProduct ArrayList **/ buildProduct.add(entry.getKey()); /*Loop through values of the corresponding key and add to buildProduct*/ for (Iterator<String> i = entry.getValue().iterator(); i.hasNext();) { Object item = i.next(); buildProduct.add(item.toString()); } /** Add buildProduct arrayList to product arrayList **/ addProduct.add(buildProduct); break; /** Exit nested loop**/ } } } } }

Hello
update to 2.1 MAF gives you , that can be added to HTML files the and remote access to the MAF since JavaScript API. Deepak mentioned "adf.mf.api.gotoFeature" and I can confirm it works HTML distance (and so it should be using local HTML). For the transmission of data, not sure whether the request URL object it. I would try here EL referencing a managed bean of application-scope defined in the scope of application (?). I tried beans controlled but so far has not tried to access the managed beans to a feature local or remote HTML using EL (although the EL is here)

How to read file(key-value) in OSB properties?
Hello
I have a scenario in which I have to read a few properties(key-value) in a file. Former entire code was developed in java and it is easy to read the java properties file.
But now I need to implement this in OSB and performance is a crucial element in this project.
I followed DVM approached defined in
http://blogs.Oracle.com/christomkins/2010/02/domain_value_maps_in_oracle_se.html and http://blogs.oracle.com/christomkins/2010/02/domain_value_maps_in_oracle_se.html
But it did not work. I have hundreds of properties (key-value pairs) to read and must transmit it to the service of the company and with the intervention of the proxy service.
What is the best approach for this (can't go to db call performance being very critical)?
Thank you
MaryseHello Francois,.
XPath in the action assign OSB should be like -
$DVMVar / ns1:rows[1]/ns1:row[1]/ns1:cell[1]/text()
where DVMVar is the content below -

How to combine the large number of tables of pair key / value in a single table?
I have a pair key / value tables of 250 + with the following features
(1) keys are unique within a table but may or may not be unique in the set of tables
(2) each table has about 2 million lines
What is the best way to create a single table with all unique key-values of all these paintings? The following two queries work up to about 150 + tables
with t1 as ( select 1 as key, 'a1' as val from dual union all select 2 as key, 'a1' as val from dual union all select 3 as key, 'a2' as val from dual ) , t2 as ( select 2 as key, 'b1' as val from dual union all select 3 as key, 'b2' as val from dual union all select 4 as key, 'b3' as val from dual ) , t3 as ( select 1 as key, 'c1' as val from dual union all select 3 as key, 'c1' as val from dual union all select 5 as key, 'c2' as val from dual ) select coalesce(t1.key, t2.key, t3.key) as key , max(t1.val) as val1 , max(t2.val) as val2 , max(t3.val) as val3 from t1 full join t2 on ( t1.key = t2.key ) full join t3 on ( t2.key = t3.key ) group by coalesce(t1.key, t2.key, t3.key) / with master as ( select rownum as key from dual connect by level <= 5 ) , t1 as ( select 1 as key, 'a1' as val from dual union all select 2 as key, 'a1' as val from dual union all select 3 as key, 'a2' as val from dual ) , t2 as ( select 2 as key, 'b1' as val from dual union all select 3 as key, 'b2' as val from dual union all select 4 as key, 'b3' as val from dual ) , t3 as ( select 1 as key, 'c1' as val from dual union all select 3 as key, 'c1' as val from dual union all select 5 as key, 'c2' as val from dual ) select m.key as key , t1.val as val1 , t2.val as val2 , t3.val as val3 from master m left join t1 on ( t1.key = m.key ) left join t2 on ( t2.key = m.key ) left join t3 on ( t3.key = m.key ) /A couple of questions, then a possible solution.
Why the hell you have 250 + tables pair key / value?
Why the hell you want to group them in a table containing one row per key?
You could do a pivot of all the tables, not part. something like:
with t1 as ( select 1 as key, 'a1' as val from dual union all select 2 as key, 'a1' as val from dual union all select 3 as key, 'a2' as val from dual ) , t2 as ( select 2 as key, 'b1' as val from dual union all select 3 as key, 'b2' as val from dual union all select 4 as key, 'b3' as val from dual ) , t3 as ( select 1 as key, 'c1' as val from dual union all select 3 as key, 'c1' as val from dual union all select 5 as key, 'c2' as val from dual ) select key, max(t1val), max(t2val), max(t3val) FROM (select key, val t1val, null t2val, null t3val from t1 union all select key, null, val, null from t2 union all select key, null, null, val from t3) group by keyIf you can do it in a single query, Union all 250 + tables, you don't need to worry about chaining or migration. It may be necessary to do this in a few passes, depending on the resources available on your server. If so, I would be inclined to first create the table, with a larger than normal free percent, making the first game as a right inset and other pass or past as a merger.
Another solution might be to use the approach above, but limit the range of keys with each pass. So pass we would have a like predicate when the key between 1 and 10 in every branch of the union, pass 2 would have key between 11 and 20, etc. In this way, everything would be straight inserts.
That said, I'm going back to my second question above, why the hell you want or need to do that? What is the company you want to solve. There could be a much better way to meet the requirement.

Using XML as a pair key / value in OSB 11 g
Hi all
I made a new Test project. There are only 2 files:
1 proxies - that contain proxy services
2 xml - containing XMLs
An example of XML (XML name - TestXML) present in the xml file:
< valueDetails >
ABC < key1 > < / key1 >
< > 123 key2 < / key2 >
a12s < key3 > < / key3 >
< / valueDetails >
I want to use in the pipeline of proxy as key-value property services. How do I get there?
I use OSB 11 GR 1 material.
Thanks in advance!
Kind regards
Karthik.Save the XML as a resource of xquery to the osb. Then, use an entitled action for load in the pipeline. For example affect XQuery resources KeyPairsXML to $keypairs. After this $keypairs will be your xml and appropriate xpath allows to recover the key you want,

Cross Tab with group by period
Good afternoon
I wonder if some can help me with this query, I am writing?
The cross-tab is for columns 1 to 31, representing the days of the month, sum of the quantity of an article sold.
In addition the company description.
I would then finish with 3 entrances in the results for each company, but these are for the sum of the quantity of items in the following periods: -.
Breakfast: 01:00 - 10:00
Lunch: 11:00 - 14:00
Dinner: 17:00 - 22:30
Yes, the company is closed for the missing periods, for example 10:00-11:00 & 14:00 to 17:00.

Hello
I'm using the version of oracle 11g.
I have a requirement where I have to produce a cross-tab as explained below. Please help me write a SQL query to do this. Thank you very much.

Doesn't have 2 separate clients, 'CCC' and 'DDD', buy 'DVD' and 'Bluray '? Why aren't the results` DVD Tape Bluray DVD 2 2 Tape 2 1 1 Bluray 2 1with 2 in the corners?
Assuming it was just error, you can do something like this:
WITH got_pairs AS ( SELECT a.product_type AS product_a , NVL (b.product_type, a.product_type) AS product_b FROM cust_product a LEFT OUTER JOIN cust_product b ON a.customer = b.customer AND a.product_type != b.product_type ) SELECT * FROM got_pairs PIVOT ( COUNT (*) FOR product_b IN ( 'DVD' , 'Tape' , 'Blueray' ) ) ORDER BY CASE product_a WHEN 'DVD' THEN 1 WHEN 'Tape' THEN 2 WHEN 'Bluray' THEN 3 END ;This assumes that the combination (customer, product_type) is unique, as in your example of data., and that only product_types is 3 in your sample data.
If these assumptions are not true, then after a few revised sample data and results, which show what you want in these cases.Sorry, I don't have an Oracle 11 database now to test this.
I can (and has) test the outer join, which combines a product_type with him that if he can not be combined with any other thing.Using a technique of 11 pivot before Oracle, the following works:
WITH got_pairs AS ( SELECT a.product_type AS product_a , NVL (b.product_type, a.product_type) AS product_b FROM cust_product a LEFT OUTER JOIN cust_product b ON a.customer = b.customer AND a.product_type != b.product_type ) SELECT product_a AS product_type , COUNT (CASE WHEN product_b = 'DVD' THEN 1 END) AS dvd , COUNT (CASE WHEN product_b = 'Tape' THEN 1 END) AS dvd , COUNT (CASE WHEN product_b = 'Bluray' THEN 1 END) AS dvd FROM got_pairs GROUP BY product_a ORDER BY CASE product_a WHEN 'DVD' THEN 1 WHEN 'Tape' THEN 2 WHEN 'Bluray' THEN 3 END ;Note that the got_pairs of the subquery is identical in the two motions.
Thanks for posting the CREATE TABLE and INSERT statements; It's very useful!

Oracle 9 append query. -
With the help of several key values to find the data
Hello, it's me again.
I had a question out about data from database and display them on a page of the ADF on Jdev 11.1.1.3.
And Mr. Daniel Atwood answered my question with this blog to follow, that wrote.
http://www.avioconsulting.com/blog/datwood/2012/06/19/using-BPM-process-variable-ADF-form-retrieve-database-information-0.
But I have another question on top that.
The Mr.Atwood example is when using a value of key 'one', what happens if I have two key values, how to set?
Here are some details:
I have a table like this
ID Type_code name
0001 05 a-blabla
0002 b 25-blabla
0002 26 b-blabla
0003-08 c-blabla
0003 25 c-blabla
0003 c 79-blabla
What I want to do is after the entry of the ID (0003) and type_code (25), he will show me the result on three components of text entry in the ADF with the value 0003, 25 page and c-blabla.
Currently, I use only ID to query the data, but I would use two key values to find specific data.
Thank you very much for taking the time to think about it,
Sincerely,
AltoIf you had multiple values to use for the request, one approach would be to create a display object. Whether you are creating the view object, in step 6, you will add two bind variables. Call a "pTypeCode" and call the other "pId". Click on the back button so that you're still in step 5, and modify the WHERE clause as follows:
(ID = :pId) and (Type_code = :pTypeCode)After you have done this, double-click the Module of the Application and add your new view object. In the tab control of data, click the Refresh button. Expand your new view object tab of data control-> expand "French"-> note that you now have a new method called "ExecuteWithParams".
Open your workflow diagram-> delete your existing "SetCurrentRowKeyValues" method-> made slide on your new "ExecuteWithParams" operation on the diagram. When you do so, you should see two settings you need to complete the dialog box. Just as you did before with the SetCurrentRowKeyValue method, set the values for the pTypeCode and the nest.
Add the case of control flow of the new method to your existing view-> make the new method, the default value.
On your form, remove the fields that have been placed here who uses the old object from view. On the tab of data control, drag the fields you want to be placed on the inside of your new view object form.
