• Export data from the database Table in the CSV file with OWB mapping

  Hello
  
  is it possible to export data from a database table in a CSV with an owb mapping. I think that it should be possible, but I didn't yet. Then someone can give me some tips how to handle this? Someone has a good article on the internet or a book where such a problem is described.
  
  Thank you
  
  Greetings Daniel

  Hi Daniel,.

  But how do I set the variable data file names in the mapping?

  Look at this article on blog OWB

• Message text to display in the carousel when no image extracted from the database

  I'm creating a carousel using pictures from a database table. All the fields in the table contains no images. Currently, it displays a cross mark on the image.

  For areas that I want to display text can be 'No Image'. To do this, I put the property 'EmptyText' of the Carousel component. But the text does not appear. Also, I do not wish the crossroads brand to display instead, I want only the text "No Image" look upwards.

  JDeveloper version - 11.1.1.7.0

  Fig-cross brand displayed for image empty

  

  Fig-EmptyText property set for the carousel component

  

  

  If I understand correctly, emptyText shows as if the entire dataset is empty, not a picture (if any rows in the resultset). It's same with af:table. Maybe I'm wrong, however.

  You can use an 'empty' image: for example to put an image of 'empty' (tailored to your needs, is perhaps 'no image' text or an icon etc.) in your project resources folder. Then, in your application, replace "null" for path to this image and it will be dispalyed instead of the generic "missing image" icon in the browser (Yes the red X is icon generic browser for missing images).

• How to find the patterns created explicitly in the database?

  Hello
  
  I'm using Oracle 11 g R1 database under Windows 2003 Server R2, my doubt is how can we find the list of schemas are explicitly created in the database, we can query this table DBA_USER or SYS. USER$ to find the list of available schemas (but it shows implicitly all the + explicitly created patterns), I need the exact list of scheme which created explicitly in the database is there any dictionary of data views is available, please advice...
  
  Thank you
  
  Shan

  But yes, you can get down SQL:

  Select a.username, a.created from dba_users a, v$ database b
  where a.created > b.created;

  Means, the users who created after the creation of the day of the database.

• Select values from the db1 table and insert into the DB2 table

  Hello
  
  I have three databases oracle running in three different machines. their ip address is different. among the DB can access databases. (means am able to select values and insert values into tables individually.)
  
  I need to extract data from the DB1 table (ip say DB1 is 10.10.10.10 and the user is DB1user and the table is DB1user_table) and insert the values into DB2 table (say ip DB2 is 11.11.11.11 and the user is DB2user and table DB2user_table) of DB3 that is to have access to the two IPs DB.
  
  How do I do this
  
  Edited by: Aemunathan on February 10, 2010 23:12

  Depending on the amount of data must be moved between DB1 and DB2, and the frequency at which this should happen, you might consider the SQL * COPY more control. I think it's very useful for one-off tasks little, so I can live within its limits of the data type. More http://download.oracle.com/docs/cd/E11882_01/server.112/e10823/apb.htm#i641251.

  Change some parameter of sqlplus session are almost mandatory in order to get decent transfer rates. Tuning ARRAYSIZE and COPYCOMMIT can make a huge difference in flow. LONG change may be necessary, too, depending on your data. The documentation offers these notes on use:

  To activate the copy of data between Oracle and databases non-Oracle, NUMBER of columns is replaced by DECIMAL columns in the destination table. Therefore, if you are copying between Oracle databases, a NUMBER column with no precision will become a DECIMAL column (38). When copying between Oracle databases, you must use SQL commands (CREATE TABLE AS and INSERTION), or you must make sure that your columns have a specified precision.

  SQL * the VALUE LONGER variable limits the length of the LONG column you are copying. If all LONG columns contain data exceeds the value of LONG, COPY truncates the data.

  SQL * Plus performs a validation at the end of each successful COPY. If you set the SQL * variable more COPYCOMMIT DEFINED to a value positive n, SQL * Plus performs a validation after copying all lots n of records. The SQL * Plus ARRAYSIZE variable SET determines the size of a batch.

  Some operating environments require that the service names be placed between double quotes.

  From a SQL * Plus term on DB3, can resemble the command to move all content from my_table in DB1 to the same table in DB2

  COPY from user1/pass1@DB1 to user2/pass2@DB2 -
  INSERT INTO my_table -
  USING select * from my_table
  

  Note the SQL code * more line-continuation character ' - '. It is used to escape the newline character in a SQL * Plus command if you do not have to type all on one line. I use it all the time with this command, but I can't locate the documentation on that right now. Maybe someone else can put their finger on it.

  There are other ways to accomplish what the command copy and it is not without its quirks and limitations, but I find that there is usefulness in an Oracle Toolbox.

• LabVIEW 2013 close when I try to read the database table.

  LabVIEW 2013 close when I try to read the database table.
  I get the error message, Labview falls just crashes. I use Labview x 32 and connective Toolkit of connectivity of database on Windows 7 x 64. I connect to PostgreSQL with ODBC driver, the connection is stable.
  In my database, I have a lot of tables, I read all those without one.
  When I try to read table bad I get data then labview crash. When I restart Labview, I have no message on the error.
  Also I try to use LabSQL-1. 1a. But it has the same result.

  I found the solution.

  I think the problem was that I have very large table in my database.

  At the beginning I received data from table with next quiry:

  SELECT column1, column2 FROM 'table ';

  But when I write then:

  SELECT column1, (column2, ',') array_to_string FROM 'table ';

  all worked!

• Failed to load existing records from the database on SD card during initialization of the application

  When the Simulator is launched upward, not able to load existing records from the database in the Inbox, so no records appear in the Inbox even though they exist in the database. It seems to be a problem with the SD card in the Simulator - the file system for the SD card is not correctly initialized when the application starts first to the top. During initialization of the application tries to access the SD card by using the following code.

  Boolean

  sdCardPresent = false;

  Enumeration e = FileSystemRegistry.listRoots ();

  If

  (e! = null) { }

  While (e.hasMoreElements ()) {}

  root = (String) e.nextElement ();

  If

  (root.equalsIgnoreCase("SDCard/")) {

  sdCardPresent =

  true;

  }

  }

  }

  sdCardPresent is always set to false and was not able to access existing records from the database. Once the application is initialized and try to create the database, the database is created successfully on the SD card.  The code is the same as above when creating the database and was able to do sdCardPresent = true.

  Is there anyway to register or add the SD card during initialization of the application or any property as System.setProperty overide the path of the default directory value?

  I use BlackBerry 9550 Simulator. I checked the "file system using PC for files from the SD card" and I use "C:\bb\SDCard" for the file system of thr.

  Also tested on the BlackBerry and found the same thing, if the device is hard reset, then it not reading the SD card as well.

  Mark the thread as solved then.

• XML from the Oracle Table data

  Hi all
  
  I'm new to this network. I'm also new to oracle XML package. I want a help with the query below.
  
  CREATE TABLE EMP (ID NUMBER PRIMARY KEY, NAME VARCHAR2 (10), TELEPHONE NUMBER);
  
  INSERT INTO EMP (ID, NAME, PHONE) VALUES (11, 'Joy', 1234);
  INSERT INTO EMP (ID, NAME, PHONE) VALUES (22, 'Mike', 5678).
  INSERT INTO EMP (ID, NAME, PHONE) VALUES (33, "Jason", NULL);
  COMMIT;
  
  I want to export data from the EMP table in an XML file with the format below.
  
  Power required:
  
  <? XML version = "1.0" encoding = "UTF-8"? > < Joy STATICDATA > < EMP > < ID > 11 < /ID > < NAME > < / NAME > < / EMP > < / STATICDATA >
  <? XML version = "1.0" encoding = "UTF-8"? > < Mike STATICDATA > < EMP > < ID > 22 < /ID > < NAME > < / NAME > < / EMP > < / STATICDATA >
  <? XML version = "1.0" encoding = "UTF-8"? > < Jason STATICDATA > < EMP > < ID > 33 < /ID > < NAME > < / NAME > < / EMP > < / STATICDATA >
  
  I used some XML functions and you wrote the following query.
  
  Select XMLROOT (XMLELEMENT (staticdata, XMLELEMENT (EMP, XMLELEMENT(ID,ID), XMLELEMENT(NAME,NAME))), version "1.0" encoding = "UTF - 8') xml EMP;

  < / STATICDATA >
  
  
  But I want the out as the power required above. all records in a single line. can someone help me achieve the desired output. also can I export all columns of the table with something like select * from the table in the XML file?
  
  Thank you
  Delobelle

  Don't know why you need it on a single line, but you could:

  Select XMLTYPE (REGEXP_REPLACE (XMLROOT (XMLELEMENT (staticdata, XMLELEMENT (EMP, XMLELEMENT(ID,ID), XMLELEMENT(NAME,NAME))), version "1.0" encoding = "UTF - 8'), CHR (10) |)) ' *<><'))>
  FROM EMP;

• Check if e-mail exist in the database table

  I stumbled on this a few times before, but I'm not familiar with this system, whenever you enter an emailaddress, you see as a clock indicating the system checks if the e-mail address may be used, in other words, is not yet in a table. I would like something similar and when the "audit" is done and the emailaddress is not in the DB table, the rest of the form appears, otherwise, an error message indicates the address is already in use. I guess this could be done using Javascript, but is there also a PHP way to do this?

  It's simple to achieve. Create a query that filters your e-mail address in the database table WHERE = POST of the email field in the form is sent. If the query returns a line then the email already exist, otherwise it is available and can treat the rest of the form.

• Logon sqlplus from the database server do not.

  Try this.
  1. the cd in your home directory.
  2. starting at the prompt, so source oraenv
  -> . oraenv
  3. When prompted enter the name of your database, in the same case, as in/etc/oratab.
  4. try to connect now
  -> sqlplus testuser / *.

  If it works for you, then you must ensure you environments ORACLE_HOME, ORACLE_SID and path are correct - as oraenv does for you.

• How to download files from the database file system.

  Hello everyone.
  
  I m trying to do a procedure to download a PDF file that is stored in the file system of the server of the database and not inside the database. The established procedure is the following:
  
  
  create or replace
  PROCEDURE PRT_PR_DOWNLOAD_FICH (v_file_name VARCHAR2
  )
  
  AS
  
  V_LENGTH number;
  Lob_loc Bfile;
  
  BEGIN
  
  
  Lob_loc: = bfilename ('DIR_OBJ', v_file_name);
  V_LENGTH: = dbms_lob.getlength (Lob_loc);
  
  owa_util.mime_header ("application/octet ', False");
  HTP.p ("Content-length: ' |") v_length);
  HTP.p ('Content-Disposition: attachment; filename = "" | ") SUBSTR (v_file_name, INSTR (v_file_name, ' /') + 1) | '"');
  owa_util.http_header_close;
  wpg_docload.download_file (Lob_loc);
  
  
  END PRT_PR_DOWNLOAD_FICH;
  
  
  This procedure receive the name of the file to download and use the wpg_docload.download_file () function. The DIR_OBJ is a directory with path from the server to the folder that contains the files I want to download.
  
  When I run this procedure I get the error: "Internal Server Error".
  
  Can someone tell me what I am doing wrong and if it is the best way to download a file directly from the database server file system?

  Hello Pedro,

  Just out of curiosity, I tried your example ;-) It works very well in my environment! (Oracle 10g with OSH and Apex 3.1.2
  But: I had to grant READ permissions on my directory object to APEX_PUBLIC_USER!

  (1) I created a "test.txt" document in the directory corresponding with my EXPDIR directory object. 'Oracle' user needs read on the file & document permissions!

  (2) give APEX_PUBLIC_USER necessary READ rights on the directory object:

  grant read on the directory expdir to apex_public_user;

  (3) create the procedure:

  CREATE OR REPLACE PROCEDURE MATTHIASH. PRT_PR_DOWNLOAD_FICH (v_file_name VARCHAR2)
  AS
  V_LENGTH number;
  Lob_loc Bfile;
  BEGIN
  Lob_loc: = bfilename ('EXPDIR', v_file_name);
  V_LENGTH: = dbms_lob.getlength (Lob_loc);

  owa_util.mime_header ("application/octet ', False");
  HTP.p ("Content-length: ' |") v_length);
  HTP.p ('Content-Disposition: attachment; filename = "" | ") SUBSTR (v_file_name, INSTR (v_file_name, ' /') + 1) | '"');
  owa_util.http_header_close;
  wpg_docload.download_file (Lob_loc);

  EXCEPTION
  WHILE OTHERS THEN
  HTP.p (substr (dbms_utility.format_error_stack (): dbms_utility.format_error_backtrace (), 1, 4000));
  END PRT_PR_DOWNLOAD_FICH;
  /

  (4) Grant execute rights on APEX_PUBLIC_USER of this procedure:

  GRANT EXECUTE ON MATTHIASH. PRT_PR_DOWNLOAD_FICH TO APEX_PUBLIC_USER;

  (5) Finally, try if download document works well:

  http://: 7777, pls, apex, MATTHIASH. PRT_PR_DOWNLOAD_FICH? v_file_name = test.txt

  I would like to know if it works!

• Download file from the database server, through application server.

  Nice day

  I use Jdeveloper 11.1.2.3.0.

  I get a way to do this. Please suggest.

  The session does not expire if you are streaming data from the application to the client. However, you will need to manage the data sent over the network, because it can make the very slow network if you send this amount of data at high speeds on the network and then to the customer. This connection between client and server is the biggest problem, because bandwidth is usually small. Think about downloading software by one side oracle (for example 1 GB), this takes time and is prone to errors.

  We did something similar by transferring the data from the database (in our case, it has been stored in a BLOB) on a dedicated server with a server web apache on it. Then, we send a link to the client, which then uses the link to get the special file server data.

  The advantage is that you don't have to code the transfer of huge files in the application of the adf but can already use ready to use of software (balancing bandwidth and the recovery of a broken download).
