• problem to extract data from the database using UTL_FILE

  Dear members
  
  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

  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.

  V_CUSTOMER_NAME  := SUBSTR(v_buffer,1,30);
  V_MANUFACTURER    := SUBSTR(v_buffer,31,70);
  V_PRODUCT_NAME    := SUBSTR(v_buffer,71,90);
  V_QTY := SUBSTR(v_buffer,91,95);
  V_SHIP_DATE := SUBSTR(v_buffer,96,115);
  V_PRICE := SUBSTR(v_buffer,116,120);

  I have modified the cells and provided data in the cells that I want to. Now, I supported on * "Send data" * button.
  It just reloaded the adhoc grid instead of submit data, I rechecked the data through data console Administrative Service are not inserted.

  You go about it the right way, once you have submitted if you réactualisiez then data values should be there, if you POV is against members of dynamic calc and then data not written to the database, you need to check the Member properties of your POV.

  • It looks like I can choose only 4000 characters using the SELECT statement (please, correct me if I'm wrong)

  I'd use the XMLGEN package. But the environment team says no mounted drives in the future with the arrival of the EXADATA.

  NO HARD DRIVE MOUNTED, NO ACCESS TO THE DATABASE DIRECTORIES

  No UTL_FILE

  I need to use the REEL spool the resulting XML data of the SELECT query.

  SQL is a standard in my org, but I can do with a PL/SQL solution also to load data into a table (cannot use a COIL with PL/SQL)

  What I do is:

  1. a column of type CLOB to a xml_report of the loading of the above SELECT query table
  2. Then using SELECT * FROM xml_report to SPOOL the data to a file report.xml

  No need of XMLTYPE data behind. Xml data stream is fine for me.

  In addition, I need to validate the XML file, also using XSD.

  Problem is that the resulting lines of the select query are supposed to be from 15000 to 20000 bytes long.

  A Suggestion or a solution to this problem would be appreciated.

  It looks like I can choose only 4000 characters using the SELECT statement (please, correct me if I'm wrong)

  You use the right method.

  There is an implicit conversion from XMLType to the data type VARCHAR2 as expected by the function TO_CLOB, where the limitation, and the error.

  To serialize XMLType to CLOB, use the XMLSerialize function:

  SELECT XMLSerialize (DOCUMENT

  XMLELEMENT ("accounts",

  ...

  )

  )

  OF ANY_TABLE;

  For the rest of the requirement, I wish you good luck trying to spool the XML correctly.

  You may need to play around with the SET LONG and SET LONGCHUNKSIZE commands to operate.

• Create the HTML using UTL_FILE

  I'll send emails using UTL_MAIL, sending the HTML, I generate dynamically to a cursor and the text with UTL_MAIL sending. SEND_ATTACH_VARCHAR2.
  
  When I get these emails, some periods are missing some very important numbers.
  
  I decided to record this HTML code in my server and then send it using UTL_MAIL. SEND_ATTACH_RAW.
  
  How can I create this HTML using UTL_FILE file and save it to a folder on my server. After you send the message, I would like to delete this file.
  
  I already have my HTML code and just want to save it as a HTML file.

  First create a virtual directory of the Oracle who can access the path specified in your server. Make sure that your procedure have write access to this directory.

  then in your code, you create something like this
  IE - myFileName 'ABCD.html' +.
  myDIR - IE 'YourOracleVirtualDir ' +.

  CREATE OR REPLACE PROCEDURE CREATE_HTML
  (myFileName IN VARCHAR2, myDir IN VARCHAR2) AS

  v_cFile UTL_FILE. TYPE_DE_FICHIER;
  v_cDir VARCHAR2 (30): = myDir.
  v_cExcept EXCEPTION;

  UTL_FILE. PUT(v_cFile,e)'|| Chr (13) | Chr (10));
  UTL_FILE. FCLOSE (v_cFile);

  EXCEPTION

  WHILE OTHERS THEN
  UTL_FILE. FCLOSE (v_cFile);
  RAISE_APPLICATION_ERROR (-20010, SQLERRM);

  to remove the file, you can use

  UTL_FILE. FREMOVE (myDir, myFileName);

  Also what yo mean "looking forward on how to proceed? Do you want to or created for use/consume in your Oracle APEX application hosted RESTful web services?

  If Yes, in your Application, you must create a RESTful Web Service reference -> shared components. Then, create a form/report based on Web Service reference.

• How to access the Non-space data of the object using the API of the HTML5

  Using the Oracle cards HTML5 API, is it possible to access the data an excerpt when generating a map?

  For example, my database has a table named ITEMS:

  Table: ELEMENTS

  COL_A

  COL_B

  COL_C

  COL_D

  COL_E

  COL_F

  GEOMETRY

  This table contains a number of objects point.  With the help of Mapviewer, I can successfully create a map by using the HTML5 API.  Here is an example of how I used the constructor 'OM.layer.VectorLayer.TYPE_JDBC' to retrieve the objects point of my database.

  pointLayer = new OM.layer.VectorLayer ("PointLayer",

  {

  infoWindow: true,

  def:

  {

  type: OM.layer.VectorLayer.TYPE_JDBC,.

  dataSource: "myDatabase",.

  SQL: "SELECT * FROM POINT."

  geometryColumn: "GEOMETRY."

  labelColumn: "COL_A."

  loadOnDemand: false,

  URL: baseURL

  },

  renderingStyle: circleMarker

  });

  How can I use the HTML5 API to access the data in the other columns (COL_A, COL_B, etc.) of my table?

  I know that the methods DisplayInfoWindow() and displayTabbedInfoWindow of the Map class to view this information by clicking on a specific point on the map.  But I would like to have access to all the points to create a table below my map showing all points (and their data) shown on the map.

  Hello

  You can try this code:

  functions var = pointLayer.getAllFeatures ();

  for (var i = 0; i)

  {

  Features [i]. GetAttributes() ["COL_A"];

  Features [i]. GetAttributes() ["COL_B"];

  ......

  Hi Maury,

  There is no need in step 2 that u mentioned above. I donot find useless a webservice?

  The process will be launched by the CSV file, then using the processing activity, you can put it in the DB.

  There should be no way where you can manually test it by giving an entry. All you can do to test is to put the file in the folder you mentioned when configuring the file adapter.

  You just need to have the composite as below:

  ReadCSVFile---> BPEL--> DB adapter

  And in your BPEL process:

  Recieve--> Transformation activity--> call activity

  Try to work on some samples listed on the oracle site and go through the below URL:

• Pump data to the directory import

  Hello!!!

  I have a slight problem with datapump. I try to import a complete database of an export that I copied to a new server.

  Windows Server 2003 R2 SP2 64-bit and EE Oracle 10.2.0.4

  I run this:

  Impdp system/dacnai directory is dumpfile 'Z:\backup\Backup_Docark' = DOCARK_FULL. DMP logfile = IMP_FULL.log full = y

  But it does not work. It does not recognize the directory (I also tried without the '). What I am doing wrong? I can't do it!

  Thank you!

  Looks like you should use impdp NETWORK_LINK clause.

  In doing so, you import the network and don't need a dump of the file at all.

• moved the file data, but the space used is always the same.

  Hi due to some problems of space I took the offline tablespace, then move the file to a location different and introduced the online storage space after renaming. After all this, the space used for the file system is always the same. How can I get the space freed up?

  Hello

  I'd be willing to bet that a core oracle process holds the lock (e.g. dbwr). use lsof (open list) command on each one and you should get the info or perhaps fuser.
