Howto set Column name from InstanceProperty?

I need to use one of InstanceProperties as some of ColumnDescriptor name.
I try:
<ColumnDescriptor NAME="%instanceproperty_1%" TYPE="NUMBER" >
and
<ColumnDescriptor NAME="name_1" TYPE="NUMBER">
<Display>
<Label NLSID="name_1">%instanceproperty_1%</Label>
</Display>
</ColumnDescriptor>
In metric table displaying "%instanceproperty_1%"
What wrong?

Well, what you're describing is a bit contrary to the design of the agent and EM. A plug-in is a target type which represents a very specific entity, whether that entity be a piece of software or hardware. The target type metadata generalizes the information important to that piece of software or hardware, so that the system can easily support different instances and collect the same information for those different instances (off different nodes).
The generalization doesn't come around the collection of the information. The information is very specific to the target type, allowing you to compare different instances of the same target type easily since the same pieces of information will be collected.
I don't think I would try to do what you are doing, but if I did, I would structure it this way...
Construct a single metric with a few columns called: OID, name, value
Allow the user to create with instance properties as you specified and pass them as input parameters to the fetchlet. You'll probably have to use the OSFetchlet and write a script to do the snmp call (since the snmp fetchlet wouldn't work, I don't think). The return from your script would be multiple rows, echoing the OID first, and then the information specific to that OID (name and value or whatever else is important).
The metric and its columns would be static, but you would be passing back a table of data which could be dynamic. So it doesn't matter to the metric how many OIDs are specified...

How to get only column names from different tables as single table columns

Hi All,
I have one requirement in which we want only column names from different tables.
for example :
I have three tables T1 ,T2, T3 having
col1 clo2 clo3 --> T1 ,
col3 col5 ,clo6 --> T2 ,
Clo6 col8 col9 --> T3
columns i want to get only all Column names from all table as single Resultset not any data from that how can i get that empty resultset
because this empty result i want to bind in datagridview(front end) as Empty resultset
Please tell me anyways to do this
Niraj Sevalkar

If I understand you want an empty result set, just with metadata. SET FMTONLY do the trick:
SET FMTONLY ON
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
SET FMTONLY OFF
Another alternative is to include an imposible contition
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
WHERE 1 = 0
If you are using a SqlDataAdapter in your client application. You can use the FillSchema method. the select command may be any select statement that returns the columns you want. Under the covers FillSchema will call SET FMTONLY ON.
If you are using SqlCommand.ExecuteReader you can pass SchemaOnly to CommandBehavior argument. SET FMTONLY ON is called under the covers. Again the select command may be any select statement that returns the columns you want.

Setting Column Names in Dynamic Pivot Query

Hi all,
I'm having trouble setting column names in a dynamic pivot query and was wondering if someone could please help me figure out what I need to do.
To help you help me, I've setup an example scenario in my hosted account. Here's the login info for my hosted site at [http://apex.oracle.com]
Workspace: MYHOSTACCT
Username : DEVUSER1
Password : MYDEVACCTAnd, here is my test application info:
ID     : 42804
Name   : dynamic query test
Page   : 1
Table 1: PROJECT_LIST         (Alias = PL... Listing of Projects)
Table 2: FISCAL_YEAR          (Alias = FY... Lookup table for Fiscal Years)
Table 3: PROJECT_FY           (Alias = PF... Intersection table containing project fiscal years)
Table 4: PROJECT_FY_HEADCOUNT (Alias = PFH... Intersection table containing headcount per project and fiscal year)Please forgive the excessive normalization for this example, as I wanted to keep the table structure similar to my real application, which has much more going on.
In my sample, I have the "Select Criteria" region, where the user specifies the project and fiscal year range that he or she would like to report. Click the Search button, and the report returns the project headcount in a pivoted fashion for the fiscal year range specified.
I've got it working using a hard-coded query, which is displayed in the "Hardcoded Query" region. In this query, I basically return all years, and set conditions on each column which determines whether that column should be displayed or not based on the range selected by the user. While this works, it is not ideal, as there could be many more fiscal years to account for, and this is not very dynamic at all. Anytime a fiscal year is added to the FISCAL_YEAR table, I'd have to update this page.
So, after reading all of the OTN SQL pivot forums and "Ask Tom" pivot thread, I've been able to create a second region labeled "Dynamic Query" in which I've created a dynamic query to return the same results. This is a much more savvy solution and works great; however, the column names are generic in the report.
I had to set the query to parse at runtime since the column selection list is dynamic, which violates SQL rules. Can anyone please help me figure out how I can specify my column names in the dynamic query region to get the same column values I'm getting in the hardcoded region?
Please let me know if you need anymore information, and many thanks in advance!

Hi Tony,
Thanks so much for your response. I've had to study up on the dbms_sql package to understand your function... first time I've used it. I've fed my dynamic query to your function and see that it returns a colon delimited list of the column names; however, I think I need a little more schooling on how and where exactly to apply the function to actually set the column names in APEX.
From my test app, here is the code for my dynamic query. I've got it in a "PL/SQL function body returning sql query" region:
DECLARE
v_query      VARCHAR2(4000);
v_as         VARCHAR2(4);
v_range_from NUMBER;
v_range_to   NUMBER;
BEGIN
v_range_from := :P1_FY_FROM;
v_range_to   := :P1_FY_TO;
v_query      := 'SELECT ';
-- build the dynamic column selections by looping through the fiscal year range.
-- v_as is meant to specify the column name as (FY10, FY11, etc.), but it's not working.
FOR i IN v_range_from.. v_range_to LOOP
    v_as    := 'FY' || SUBSTR(i, 3, 4);
    v_query := v_query || 'MAX(DECODE(FY_NB,' || i || ',PFH_HEADCOUNT,0)) '
      || v_as || ',';
END LOOP;
-- add the rest of the query to the dynamic column selection
v_query := rtrim(v_query,',') || ' FROM ('
    || 'SELECT FY_NB, PFH_HEADCOUNT FROM ('
    || 'SELECT FY_ID, FY_NB FROM FISCAL_YEAR) A '
    || 'LEFT OUTER JOIN ('
    || 'SELECT FY_ID, PFH_HEADCOUNT '
    || 'FROM PROJECT_FY_HEADCOUNT '
    || 'JOIN PROJECT_FY USING (PF_ID) '
    || 'WHERE PL_ID = ' || :P1_PROJECT || ') B '
    || 'ON A.FY_ID = B.FY_ID)';
RETURN v_query;
END;I need to invoke GET_QUERY_COLS(v_query) somewhere to get the column names, but I'm not sure where I need to call it and how to actually set the column names after getting the returned colon-delimited list.
Can you (or anyone else) please help me get a little further? Once again, feel free to login to my host account to see it first hand.
Thanks again!

How to Select data using same column name from 3 remote database

Hi,
Can anyone help me on how to get data with same column names from 3 remote database and a single alias.
Ex.
SELECT *
a.name, b.status, SUM(b.qty) qantity, MAX(b.date) date_as_of
FROM
*((table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3)a,*
*(table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3)b)*
WHERE b.dept = 'finance'
AND a.position = 'admin'
AND a.latest = 'Y' AND (b.status <> 'TRM') AND b.qty > 0;
GROUP BY a.name, b.status ;
NOTE: the bold statements is just an example of what I want to do but I always gets an error beacause of ambiguous columns.
Thanks in advnce. :)

Each object must be uniquely identified. So you cannot do this:
select * from (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) a3 objects cannot share the same alias. Example:
SQL> select * from (dual, dual) d;
select * from (dual, dual) d
ERROR at line 1:
ORA-00907: missing right parenthesisYou need to combine the objects - using a join or union or similar. So it will need to be done as follows:
SQL> select * from (select * from dual d1, dual d2) d;
select * from (select * from dual d1, dual d2) d
ERROR at line 1:
ORA-00918: column ambiguously definedHowever, we need to have unique column names in a SQL projection - so the join of the tables need to project a unique set of columns. Thus:
SQL> select * from (select d1.dummy as dummy1, d2.dummy as dummy2 from dual d1, dual d2) d;
DUM DUM
X X
SQL> I suggest that you look closely at what scope is and how it applies in the SQL language - and ignore whether the objects referenced are local or remote as it has no impact to fundamentals of scope resolution.

How to pull only column names from a SELECT query without running it

How to pull only column names from a SELECT statement without executing it? It seems there is getMetaData() in Java to pull the column names while sql is being prepared and before it gets executed. I need to get the columns whether we run the sql or not.

Set Folder Name From File Name Inclosed.

Hello scripters,
There has been quite a few topics about setting file names from parent folders. I believe it's possible but not sure how to reverse this process. That is to say set the folder name from a file in the folder. This is what I'm imagining.
I've got a folder. In the folder are 100 folders with the names "untitled folder xxx" In side I've got files that are all named and numbered.
For example,
untitled folder/B-day 001~050.jpg
untitled folder 50/At The Park 001~020.jpg
I would like a script to change the name of the parent folder of the files that it houses.
So untitled folder becomes
B-Day
untitled folder 50 becomes
At The Park
etc…
I think getting the name of the first file (minus the index number) would be easiest.
Any help or futher questions are greatly appreciated.
Maximilian

Working backwards...
Assuming all the files have the same name structure (e.g. end in the format "xxx~xxx.jpg" you can get the base name using:
<pre class=command>set baseName to characters 1 through -13 of filename as text</pre>
This cuts off the last 12 characters of the file name.
Once you have a folder, you can get the names of files in the folder via the Finder. for sanity's sake I'd ask the Finder for the first item, just in case there's more than one file:
<pre class=command>set filname to name of first item of (files of folder theFolder)</pre>
And if all the folders are in one top folder, you can iterate through them like:
<pre class=command>repeat with eachFolder in (every folder of folder topFolder)</pre>
So now, string it all together:
<pre class=command>tell application "Finder" -- we'll use the Finder to do the legwork
set topFolder to (choose folder with prompt "Choose the top level folder" ) -- get the top folder
repeat with eachFolder in (every folder of folder topFolder)
set fileName to name of first file of (files of folder topFolder)
set baseName to characters 1 through -13 of fileName as text
set name of folder eachFolder to baseName
end repeat
end tell</pre>
Note there's no error checking - the script will fail if there are no files in any particular folder, but it should get you going.

How to dynamically set column name in Answers

Hi.
How to dynamically set column name in Answers, for example I want to put presentation variable in column header. Is this possible?

http://108obiee.blogspot.com/

May be a rude way .. but it works.
Add narrative view and use Java script to change the column headings based on the variables.
<script language="javascript" type="text/javascript">
var a = document.getElementById('idResultsTableParent');
var rows= a.getElementsByTagName('tr');
rows[1].cells[1].innerText ="@{Presentation Variable}";
</script>

Query the column names from Public database links

Greetings,
I would like to retrieve the list of all the column names from a public database link. A regular ALL_TAB_COLUMNS doesn't seem to be working.
Thanks

Hi,
I think your DBA needed to create a synonym for you to have access of that remote database view.
CREATE SYNONYM synonym_name
FOR view_name@db_link;Then you can find the column names by
DESC synonym_nameGuru's , please correct me If I am wrong.
Thanks

How to set column names when not using object of row data in constructer

hello i am using JTable constructer as
public JTable(int numRows,
int numColumns)
can i set column names for the columns .How?

hi,
sure you can: Create a subclass of DefaultTableModel and overwrite the method public String getColumnName(int) which returns the column name of a specific column. Then use this subclass as the data model for the table.

Getting column names from SYS_REFCURSOR

Hi everybody, i have a SYS_REFCURSOR in a procedure. And i open it and fetch cursor to a record as follows:
OPEN curgroup FOR vexpr2;
LOOP
FETCH curgroup INTO recType;
END LOOP;
recType is a Record, has two variables. Anyway, the question is can i get the column names from refcursor?
like recType.COLUMN1 (Column1 is not a record variable ) ????
or is there anything else to perform this operation?

Hi,
Despite what Billy states it is very possible to get the column names from a weak ref cursor, or describe a ref cursor with PL/SQL. It has been possible since 8i, it just relies on the little known fact that a ref cursor in PL/SQL translates directly to a ResultSet in Java so we can use a tiny JSP in the DB.
Here is the link to the completely free, Open Source code which allows you to do this: [XUTL_REFCURSOR|http://www.chrispoole.co.uk/apps/xutlrefcursor.htm]
And a little example:
SQL> variable scott_cursor refcursor
SYS@ORA10GR2
SQL> begin
2 open :scott_cursor for select * from scott.emp;
3 end;
4 /
PL/SQL procedure successfully completed.
SYS@ORA10GR2
SQL> begin
2 xutl_refcursor.describe_columns(:scott_cursor);
3 end;
4 /
PL/SQL procedure successfully completed.

SQL>As the demo shows describing the ref cursor does not affect the cursor in any way, it is not selected from. It is not converted into a DBMS_SQL cursor and can be passed to a front end.
[XUTL_REFCURSOR|http://www.chrispoole.co.uk/apps/xutlrefcursor.htm] is designed to have exactly the same output and uses the same return type as DBMS_SQL DESCRIBE COLUMNS, to enable pre-existing code that uses that API to be quickly re-used.
