extracting data from the CLOB using materialized views
Hello
We have xml data from clob which I have a requirement to extract (~ 50 attributes) on a daily basis, so we decided to use materialized views with refreshes full (open good suggestions)
I make use of series for the SUBSTR and INSTR function to extract the fields of a data file and carve out spaces based on the number of post mentioned in the Excel worksheet. I was able to extract the first 3 areas namely, customer, manufacturer, product, but for quantity, requested delivery date, price, I can't do it.
the flat file structure is as follows:
Field Position From Position To
CUSTOMER_NAME 1 30
MANUFACTURER 31 70
PRODUCT_NAME 71 90
QUANTITY 91 95
REQUESTED_SHIP_DATE 96 115
REQUESTED_PRICE 116 120
Sample data in the flat file is as follows:
BESTBUY SONY ERICSSON W580i 25 1-AUG-2008 50
BESTBUY SAMSUNG BLACKJACK 50 15-JUL-2008 150
BESTBUY APPLE IPHONE 4GB 50 15-JUL-2008
BESTBUY ATT TILT 100 15-JUN-2008
BESTBUY NOKIA N73 50 15-JUL-2008 200
My program code is the following:
CREATE OR REPLACE PROCEDURE ANVESH.PROC_CONVERSION_API(FILE_PATH IN VARCHAR2,FILE_NAME IN VARCHAR2)
IS
v_file_type utl_file.file_type;
v_buffer VARCHAR2(1000);

I was able to extract the first 3 fields of the file data, but when I use the same SUBSTR and INSTR functions to extract then three fields I am unable to do so (I get 5, 6 on the ground as well when I extract the 4th field). I've hardcoded the position values in these functions, such as mentioned in the structure of flat file.
It would be great if someone can tell me how to extract the three fields in the flat file.
Thank you Romaric
Romaric,
Why you use v_end_pos to trim spaces when you know the beginning and end of all columns positions? I do not see the code when you check out the values of other 3 columns (Qty, Date & price).
You can use substr underneath rather do SELECT each time.
I have a table that has two columns date all the hours of the base and the response time. I want to extract data from the date corresponding previous hourly basis with the response time. The data will be loaded into the table every midnight.
for example: today date 23/10/2012 I want to extract data from 22/10/12 00 to the 22/10/12 23
The sub query pulls the date as demanded, but I'm not able to take the time to answer.
with one also (select min (trunc (lhour)) as mindate, max (trunc (lhour)) as AVG_HR maxdate) SELECT to_char (maxdate + (level/25), "dd/mm/yyyy hh24") as a LEVEL CONNECTION dates < = * (1) 24;
Please help me on this.
Try this
SELECT * FROM table_nm
WHERE to_char(hour,'DD') = to_char(SYSDATE-1,'DD')
In my VI I need to extract the data from the graph xy of one cursor to another, how can I do this?
I want to extract all the data between the two sliders, to develop.
Thank you
In addition to everything said altenbach, you want the slider list: property of the Index. That will tell you where in the table of data, the sliders are.
The attached VI shows how we can work and also meaningless how it can be with common types of XY data.
I would prefer to extract data from a PDF file and convert them to XML. Is there an API that allows to convert a PDF to an Adobe XML format? Ideally, I would like to add a few JAR files to my classpath, similar to PDFBox. I don't want to install a bunch of components side server or something like that.
Thank you!
Then Adobe does not offer a solution that meets your needs - sorry.
Our solution on the server side is our LiveCycle product family which, however, includes a collection of Java APIs.
I read data from a STI flow meter using the base series writing and reading which used the VISA. The read string begins with 'OK' or an error code, then a carriage return, then the data follows streaming rate temp pressure flow rate comma comma comma comma Temp... and so on. The string ends with a CR LF. I need to pull the flow, temperature and pressure data out of the string and write it to a file. I have difficulties to find a function that will retrieve the data for the string. Any suggestions? Thank you.
Try the subset of string in the palette of the chain.
Or match the model if you want a more direct control.
Also a good way is the string analysis, but you must be willing to read oexactly, what happens or an error, pass the entrance.
I am doing a report at the APEX. the user selects two dates and click on the GO button - I have a stored procedure linked to this region of outcome for the stored procedure is called.
my stored procedure does the following-
using dates specified (IN) I do question and put data in a table (this painting was created only for this report).
I want to show all the data that I entered in the table on my APEX report the same procedure call. can I use Ref cursor return? How to do this?
Currently, I use another button in the APEX that basically retrieves all the data from table. Basically, the user clicks a button to generate the report and then another button for the report. which is not desirable at all :(
I m using APEX 3.1.2.00.02 and Oracle 10 database.
pls let me know if you need more clarification of the problem. Thanks in advance.
Kind regards
Probashi

APEX to base a report out of a function that returns the sql code... Your current code goes against a Ref cursor returns the values...
See this thread regarding taking a ref cursor and wrapping it in a function to channel out as a 'table' (use a cast to cast tabular function vale)...
I have the XML loaded from a Flash panel language translation file strings in an XML variable. Works very well. Traces out - shown below.
When I try to extract the data as XML < trans-unit >, I get an 1120: access of undefined property unit.
function completeHandler(event:LoaderEvent):void {
var stuff:XMLLoader = LoaderMax.getLoader(arrayXMLFiles[0]);
var moreStuff:XML = LoaderMax.getContent(arrayXMLFiles[0]);
ssDebug.trace(moreStuff); // this works with output shown below
ssDebug.trace(moreStuff.xliff.file.body.trans-unit); // - error here
}
The Trace is here:
<xliff version="1.0" lang="en" xmlns="http://www.w3.org/XML/1998/namespace">

I found a code by looking at a similar problem - I do not know how to retrieve other data (as I guess) the rest of the HTML in the code. I need to find a better reference with details and examples.
Hi all I have a CLOB field with data, I want to copy all the ot its data to another field of varchar2 to the same table. How, please? I think that I should use the Update statement, but how?
Note: Iam using DB Oracle 10g R2
You can just do a simple UPDATE, but if you have the adta in your CLOB which is too big to fit in your column VARCHAR2 column, you will not be able to get it all:
UPDATE my_table SET my_varchar2_column = SUBSTR(my_clob_column,1,[size of my_varchar2_column];
Hi, we need fill a projected account using the last current month and year of actual expenditures in the rules. Example: S #Fcst.A #101.Y #2011.P #Mar = S #Actual.A #102.Y # (most cuurent year system). P # (more recent period of system).
Does anyone know if this is possible? We are on HFM 4.0.1
Thanks in advance!

You can use vba, Month (Now (), and Year (Now ()) to get 3 and 2010 respectively.
On the grid, we have the ability to import the data in grid. However, on the Import Wizard, the only option that appears is import values separated by comma (CSV). Options for importing to Excel not displayed. Why is it other import options is not available?
You may need to register the OCX that offer this feature.
I need to run the IBM Cognos Data Manager 10.1 version ETL tool for extracting data from the Oracle11.1 database.
My understanding is that, from the point of view of database, the best way would to have a stored procedure that will provide a reference cursor in the ETL client tool.
However, a database procedure the ETL tool running seems not to be possible in this version of the data manager.
If someone has done this before? What is the best way for this snippet to do?
Thank you

My reading of original question: "What is the best way for this snippet to do?"
Sorry - is NOT helping.
The BEST way to extract data from a table is to use a SELECT statement.
You said you want to do.
So just repeat your original question instead of those that ask you to answer will not move forward us.
