Build the query in PLSQL to return well formed XML with multiple records
HelloIt's very urgent. I am creating a PLSQL query who must retrieve all records in the table of "tbl_Emp" oracle database in a well-formed xml format. The format is given below
* < employees xmlns = "http://App.Schemas.Employees" xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" > *.
* < employee > *.
* < name > < / name >. *
* < Last_Name > < / Last_Name > *.
* < / employee > *.
* < employee > *.
* < name > < / name >. *
* < Last_Name > < / Last_Name > *.
* < / employee > *.
*...*
* < / employees > *.
To retrieve data in above format, I tried to create a query for a long time as below
SELECT XMLElement ('employees',
XMLAttributes ('http://App.Schemas.Employees' AS 'xmlns',
(* "http://www.w3.org/2001/XMLSchema-instance" AS "xmlns: xsi"), *.
XMLElement ("employee", XMLForest (First_Name, Last_Name)))
AS 'RESULT '.
OF tbl_Emp;
But it does not give me the desired output. It creates the < Employees > tag with each individual record which I didn't need. I need tag < Employees > the root tag and the tag < employee > repeat and wrap each individual record. Please help me in that it's very urgent. Thank you.
Hello
Remember that nothing is 'urgent' here, and repeating it will probably produce the opposite effect.
If you need a quick answer, provide all necessary details, in the first place:
-version of db
-test with sample data and DDL cases
That being said, it's easy, it takes group using XMLAgg:
SELECT XMLElement("Employees"
, XMLAttributes(
'http://App.Schemas.Employees' AS "xmlns"
, 'http://www.w3.org/2001/XMLSchema-instance' AS "xmlns:xsi"
)
, XMLAgg(
XMLElement("Employee"
, XMLForest(
e.first_name as "First_Name"
, e.last_name as "Last_Name"
)
)
)
) AS "RESULT"
FROM hr.employees e

Build the query to select date with status
Hi guys,.
Grateful if you can advise me on how to build the query on below scenario:
Table A
Date
11.44.39.000000000 12-OCT-14 AM ASIA/SINGAPORE
11.44.35.000000000 16-SEP-14 AM ASIA/SINGAPORE
11.44.42.000000000 22-SEP-14 AM ASIA/SINGAPORE
The result of the query:
Date Status
11.44.39.000000000 12-OCT-14 AM ASIA / SINGAPORE inactive
11.44.35.000000000 16-SEP-14 active AM ASIA/SINGAPORE
11.44.42.000000000 22-SEP-14 AM ASIA/SINGAPORE inactive
Basically, the logic, I wanted is
Active principles: today date or max (date) < sysdate
Otherwise will be inactive
And there is 1 active date in time.
Thanks in advance

Sorry, we don't know what you want.
Are you saying that 1 row (maximum) can be assigned status = 'Active' and if 2 or more lines are eligible, the last of them will be called 'Active'?
If so:
CASE
WHEN tmstmp<=>
OR ROW_NUMBER () OVER (PARTITION BY CASE
WHEN tmstmp<=>
THEN "could be."
ANOTHER 'No Way'
END
ORDER BY tmstmp DESC
) = 1
THEN "active."
ELSE 'inactive '.
END
If you would care to post CREATE TABLE and instructions INSERT for some samples, so I could test it.
DATE is not a very good name for a column, especially if the column is a TIMESTAMP, not a DATE. I called the TMSTMP instead of the DATE column.

enforcement procedure with success and data not inserted into the table 'dq_summary '.I'm sorry. But there is no kind of say that way. The code is undesirable. The approach is wrong. This will not happen. This will cause the fragmentation of memory in the shared Pool. This will lead to another session being impossible to analyze the sliders because of the fragmented memory.
Not only that. The underlying data model is questionable.
All this seems a candidate perfect as an example of how NOT to design and code and use Oracle.

How to build the query SQL for indexes work based on data - dict.?
Hello
I want to build the index 'create' - statement to all indexes have worked-based on the data dictionary.
For example:
create indexes tab1.ind1
on tab1 (lower (col3), lower (col1), col2, col4)
Tablespace "index."
I know I'll find all needed information views all_indexes, all_ind_columns and all_ind_expressions. During the generation of the create statement for the index of the order of the indexed columns must be correct (the order of the indexed column can be achieved using the "position_colonne" column of seen all_ind_columns and all_ind_expressions). But what would be the best way to provide all the necessary information in the right order?
One way would be a PLSQL procedure that puts it all together - but is it possible to use a single SQL statement?
Any help will be appreciated.

I worked through the training from the Source Flex2 book (trapper, Boles, Talbot, etc.). In Lesson 17, this is to access the objects on the server side.
A piece of code accesses a CF model, which brings in an XML file:
-----
< mx:HTTPService id = "prodByCatRPC".
' URL =' http://localhost/flexGrocer/xml/categorizedProducts.cfm '
result = "prodByCategoryHandler (Event)" "
resultFormat = "e4x" / >
-----
The CF file of the book plate has the following:
----
< name cfheader = "Expires" value = "#now ()" # "/ >"
< cfxml variable 'x' = >
< cfinclude template = "categorizedProducts.xml" >
< / cfxml >
< cfset xmlObject = ToString (xProducts) >
< cfcontent type = "text/xml" / >
#variables.xmlObject # < cfoutput > < / cfoutput >
-----
Using the Flex file, I get a Runtime message that seems to indicate that the XML is not well-formed. (Here's a bit of the message, not sure that I understand it!) :
[CPP faultString = error "" error #1088: the markup in the document following the root element must be well formed. "faultCode =" Client.CouldNotDecode"faultDetail ="null"]
I'm ASSUMING that the CF page does not return the xml as you wish, because if I simply change the flex http service call in the xml file that the CF page is notably, the flex application runs as scheduled and without errors:
----
' URL =' http://localhost/flexGrocer/xml/categorizedProducts.xml '
----
(something in the mech detachment made the statement url above messed, but you probably get what I mean)
I'm a CF developer and have not used the exact method of the book to get the generated XML from CF, I did so successfully for Spry and other things.
I tried some ot the things I had to do to get the CF generated XML to work in Spry with this flex, but nothing helped. Tried to add a reset = "true" with the tag cfcontent; " tried to wrap the cfcontent to output; added cfprocessing tags to suppresswhitespace.
Appreciate all the thoughts/help on how to solve this problem. In addition, if others agree that the problem is with the XML that is generated rather than anything else.
Thank you
KeithAfter experimenting with several, I found the problem: didn't set the parameters of CF to NOT see the debug output. Make this setting, makes everything work fine.
Oh, the little things that cause big problems!

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.
Thank you

Need help to build the query to group the lines
Hello all, hope someone can help me with this. I am working in Oracle 11 g PL/SQL 11.2.0.2.0.
I have the following query, which does exactly what I need, but I have been invited to consolidate the results in a specific way and I can't do that. First of all the existing request:

So an expected result would look something like:SELECT facility_id ,facility_type ,COUNT (CASE WHEN component_type = 'ATTACH2NDPARTY' THEN 1 END) AS ATTACH2NDPARTY ,COUNT (CASE WHEN component_type = 'ATTACH3RDPARTY' THEN 1 END) AS ATTACH3RDPARTY ,COUNT (CASE WHEN component_type = 'BREAKERGT' THEN 1 END) AS BREAKERGT ,COUNT (CASE WHEN component_type = 'BREAKERUSS' THEN 1 END) AS BREAKERUSS ,COUNT (CASE WHEN component_type = 'CAPACIFORMER' THEN 1 END) AS CAPACIFORMER ,COUNT (CASE WHEN component_type = 'CAPACITOR' THEN 1 END) AS CAPACITOR ,COUNT (CASE WHEN component_type = 'CEFIBEROPTIC' THEN 1 END) AS CEFIBEROPTIC ,COUNT (CASE WHEN component_type = 'ELASTIDISCONN' THEN 1 END) AS ELASTIDISCONN ,COUNT (CASE WHEN component_type = 'NETWORKPROTECT' THEN 1 END) AS NETWORKPROTECT ,COUNT (CASE WHEN component_type = 'POLE' THEN 1 END) AS POLE ,COUNT (CASE WHEN component_type = 'REACTOR' THEN 1 END) AS REACTOR ,COUNT (CASE WHEN component_type = 'RECLOSER3PUPOIL' THEN 1 END) AS RECLOSER3PUPOIL ,COUNT (CASE WHEN component_type = 'RECLOSERTSUP' THEN 1 END) AS RECLOSERTSUP ,COUNT (CASE WHEN component_type = 'RECLSR3PCNTRL3A' THEN 1 END) AS RECLSR3PCNTRL3A ,COUNT (CASE WHEN component_type = 'RECLSR3PCNTRLNT' THEN 1 END) AS RECLSR3PCNTRLNT ,COUNT (CASE WHEN component_type = 'RECLSRTSCNTRL' THEN 1 END) AS RECLSRTSCNTRL ,COUNT (CASE WHEN component_type = 'RECTIFIERUSS' THEN 1 END) AS RECTIFIERUSS ,COUNT (CASE WHEN component_type = 'REGULATORJOINT' THEN 1 END) AS REGULATORJOINT ,COUNT (CASE WHEN component_type = 'REGULATOROH' THEN 1 END) AS REGULATOROH ,COUNT (CASE WHEN component_type = 'REGULATORUSS' THEN 1 END) AS REGULATORUSS ,COUNT (CASE WHEN component_type = 'RMS' THEN 1 END) AS RMS ,COUNT (CASE WHEN component_type = 'SPLICEPRIMARY' THEN 1 END) AS SPLICEPRIMARY ,COUNT (CASE WHEN component_type = 'STREETLIGHT' THEN 1 END) AS STREETLIGHT ,COUNT (CASE WHEN component_type = 'SWITCHSCADA' THEN 1 END) AS SWITCHSCADA ,COUNT (CASE WHEN component_type = 'TAPCHANGER' THEN 1 END) AS TAPCHANGER ,COUNT (CASE WHEN component_type = 'TRAFFICSIGNAL' THEN 1 END) AS TRAFFICSIGNAL ,COUNT (CASE WHEN component_type = 'TRANSF480' THEN 1 END) AS TRANSF480 ,COUNT (CASE WHEN component_type = 'TRANSFGROUND' THEN 1 END) AS TRANSFGROUND ,COUNT (CASE WHEN component_type = 'TRANSFISOLATION' THEN 1 END) AS TRANSFISOLATION ,COUNT (CASE WHEN component_type = 'TRANSFOH' THEN 1 END) AS TRANSFOH ,COUNT (CASE WHEN component_type = 'TRANSFUG' THEN 1 END) AS TRANSFUG ,COUNT (CASE WHEN component_type = 'TRANSFURD' THEN 1 END) AS TRANSFURD ,COUNT (CASE WHEN component_type = 'TRANSFUSS' THEN 1 END) AS TRANSFUSS FROM (SELECT fy.id AS facility_id ,fy.external_facility_id ,fy.flty_facility_type as facility_type ,cp.cpty_component_type as component_type FROM facilities fy LEFT OUTER JOIN components cp ON cp.facility_id= fy.id ORDER BY fy.id DESC) GROUP BY facility_id, facility_type

In order to explain my problem, I'll give my data first and then explain what I am trying to accomplish.
Oracle: 10g
Table = tb.xInfo
"So what I try to do based on the above data is: summarize all specific amounts, exit it years in years like 1995-1997 column" and all styles of there in the column style, with Chris, I want out of his STYLE values separated by a comma.NAME STYLE YEAR AMOUNT SEC_ID BOB BLUE 1995 6 1 BOB BLUE 1996 8 1 BOB BLUE 1997 7 1 CHRIS RED 1995 4 1 CHRIS PURPLE 1996 8 1 CHRIS RED 1997 5 1 DAN YELLOW 1995 9 1 DAN YELLOW 1996 4 1 DAN YELLOW 1997 1 1
Desired result set
This is the code I tried but did not have much success:NAME STYLE YEAR AMOUNT BOB BLUE 1995-1997 21 CHRIS RED, PURPLE 1995-1997 17 DAN YELLOW 1995-1997 14
The above doesn't seem to work.select name, (CASE WHEN count(style) = 2 THEN STYLE || ', ' || STYLE ELSE STYLE END) as style, '1995-1997' AS YEAR SUM(AMOUNT) as amount from ( select name, style, year, amount from tb.xInfo where year in (1995,1996,1997) and sec_id = 1 and name ) Group by name, style, amountHello
Here is an example of SYS_CONNECT_BY_PATH, using the example of data published by Mwooldridge:
WITH got_style_num AS ( SELECT DISTINCT name , style , SUM (amount) OVER ( PARTITION BY name) AS total_amount , DENSE_RANK () OVER ( PARTITION BY name ORDER BY style ) AS style_num FROM msw_test WHERE year IN (1995, 1996, 1997) AND sec_id = 1 ) SELECT name , LTRIM ( SYS_CONNECT_BY_PATH (style, ', ') , ', ' ) AS styles , '1995-1997' AS years , total_amount FROM got_style_num WHERE CONNECT_BY_ISLEAF = 1 START WITH style_num = 1 CONNECT BY style_num = PRIOR style_num + 1 AND name = PRIOR name ;Create dynamically the years column, as did Mwooldrige, is a good idea. To modify the above query, use the MIN and MAX functions analytical in the subquery got_style_num.
Alternatively, you can use the SYS_CONNECT_BY_PATH to generate a string like ' 1995, 1996, 1997. This could be very useful if some names, it was missing a few years; then you might get results like ' 1995, 1997' or '1995' dynamically.The above query lists the styles alphabetically. In the sample data you posted, you RED prior to VIOLET. If it's important, explains what order you want.

I need all the information to display so I need the scroll key to work, but it is not editable.
Thanks for the help!
Tania
You can define a field with strike and validate to prevent the user from changing the value of the field. First, set the field to multiline and 'Scroll long text' and the default value for the text to display in the field. Then add a custom script to strike which is:
Custom keystroke script
Event.RC = false;
and to be complete, the validation script customized according to:
Custom validation script
If (event.value! == event.target.defaultValue) event.rc = false;
These scripts will prevent the value to be changed, at least in Acrobat and Reader if JavaScript is enabled.

If 'this' which is an area of list ['a', 'first'] ['b', 'second'] is set to a or b it works perfectly, showing 'a' in the code and the 'first' in the Desc as follows:
a first
OR
second b
but when I select both this list looks like this:
First Prime
second second
Any ideas on how to preserve the letters without making the code too complex or difficult to maintain?
Thank you!!!
JavaScript appears to be similar:
var r = ""; for (var i = 0; i < this.dataNode.nodes.length; i += 1) { r += this.dataNode.nodes.item(i).value + " " + this.getDisplayItem(i) + "\n"; } Textfield1.rawValue = r; -
Build the string separated by commas in query with Expression box sub
Oracle 10g on Windows XP
Consider the following query:
Select batch_id, tr state_tag_seq where request_type in (select case WHEN PX = 'RETURN' AND 'TRANSFER' |) «, » || "PUBLIC TRANSIT"
WHEN PX = "RFT" THEN "TRANSIT".
ELSE 'Invalid '.
END
OF THE DOUBLE
) ;
In this case, PX is accepted to execution of the user interface.
I'm having no rows returned (all valid lines matching in DB) for the following case assessment
WHEN PX = 'RETURN' THEN 'TRANSFER '. «, » ||' Transit "(PX when is evaluated to 'RETURN')
The application works well when it px IS estimated to be "PCR" (as the evaluated expression is just a string ('TRANSIT') single, not separated by commas, as in the other case)
Hiow do rewrite this query, if it gives a correct result? In other words, I actually build the query string slot, which is assessed by the external when query clause.
I think it might be a specific way to use quotes in my case expression, but I'm reaching an impasse. Any help is appreciated.
Thank you
SRYou can try
select batch_id, state_tag_seq from tr where request_type member of case when px = 'RETURN' then sys.dbms_debug_vc2coll ( 'TRANSFER', 'TRANSIT' ) when px = 'RFT' then sys.dbms_debug_vc2coll ('TRANSIT') else sys.dbms_debug_vc2coll ('Invalid') end -
When you perform the query from the query, it assumes that the field is numeric
I have a query that has 30 some files inside from an AS400 file. Now, when I do a query on the query, he thinks one of the columns is a numeric field, even if it is not. Now I do the same thing with another query (with the same file and fields, just different data) and it works fine.
This is the error I get: the 73 "d" value cannot be converted to a number
This column looks like this for example
75
75
71
71
75
73
75
63%
etc. (the 73D is the only one in this column)
Now in the query of queries I question not even this field (there are about 10 fields in the query, and I want the results of one) and then I get the above error. Any ideas?
Thanks in advance,

Thus, when it hits this row it will fail.
If you do not use the data in that column, and then not put it back. Otherwise, use it.
