• external table data with several locations pump

  Hello
  I'm on:
  Oracle Database 10 g Enterprise Edition release 10.2.0.3.0 - 64biit
  SunOS 5.10
  
  I am trying to create a table of data pump external at the same time, with the location of the files previously created using pump.
  This is the same as the example given in step 10-13 here:
  http://docs.Oracle.com/CD/B19306_01/server.102/b14215/et_dp_driver.htm#i1007502
  
  But when I do this and select all the lines in the resulting table, I get the error:

  Combination dump files

  Files dump populated by different external tables can all be specified in the LOCATION of another external table clause. For example, data from different databases can be unloaded in separate files, and these files can then be included in an external table defined in a data warehouse. This provides an easy way to aggregate data from multiple sources. The only restriction is that the metadata for all external tables is exactly the same. This means that the game characters, time zone, schema name, table name, and column names must match. In addition, the columns must be defined in the same order, and their data types must be identical. This means that after you create the first external table you must remove it so that you can use the same table name for the second outer table. This ensures that the metadata in two dump files is the same and they can be used together to create the external table even.

• jump the last record loading using external table

  Hi gentlemen,
  
  I have a requirement to load data from text file of oracle database by using the external table. I need to remove the header records and complementary.
  
  I can use the skip option to remove the header, IE front-line.
  
  Is it possible to remove the additional record (IE last line) using the external table.
  
  
  Thanks in advance.

  Hi, Kalai,

  ... issuelastUpdatedTime TANK (17) DATE_FORMAT TIMESTAMP MASK "YYYYMMDDHHMISSSSS".

  I think the desired format is

  YYYYMMDDHH24MISSFF
  

  JACKY is the number of seconds since the start of the day : 17000 seconds after the beginning of a day is 04:43:20. You probably wouldn't SSSSS if you also use HH (or HH24) or MI.
  If 17000 means 17,000 seconds since the start of the minute , then use SSFF. FF is for the fractional part of the second, no matter how many numbers that is.

• How to load data from matrix report in the base using ODI table data

  Hello
  
  How to load matrix report data in the base table data using oracle Data Integrator?
  
  Description of the requirement:
  
  This is the data from matrix report:

  JOB                       DEPT10                DEPT20  
  ___________________________ _____________
  ANALYST                                           6000
  CLERK                   1300                     1900 

  Need to convert it to the format below:
  

  JOB                             Dept                        Salary
  _____________________________________________
  ANALYST                  DEPT10      
  ANALYST                  DEPT20                     6000
  CLERK                       DEPT10                    1300
  CLERK                       DEPT20                    1900
      

  Thank you for your help in advance. Let me know if any other explanation is needed.

  Your list seems to be a bit restrictive, you can do much more with the procedures of ODI.

  If you create the new procedure and add a step. In the 'source' tab command you define technology and pattern according to your source database. Use the unpivot operator as described in the link, please, instead of using "SELECT *' use the column names and aliases for example:"

  SELECT workstation,
  deptsal as deptsal,
  saldesc as saledesc
  OF pivoted_data
  UNPIVOT)
  deptsal-<-->
  FOR saldesc-<-->
  IN (d10_sal, d20_sal, d30_sal, d40_sal).<-->
  )

  Then in your tab 'command on target' defined technology and drawing on your target db, then put your INSERT statement for example:

  INSERT INTO job_sales
  (employment,
  deptsal,
  saledesc
  )
  VALUES
  (
  : job,.
  : deptsal,.
  : saledesc
  )

  That's why you use bind variables from source to load data into the target.

  Obviously if the source and target table is in the same database, you can have it all in a single statement to the "command on target' as

  INSERT INTO job_sales
  (employment,
  deptsal,
  saledesc
  )
  SELECT workstation,
  deptsal as deptsal,
  saldesc as saledesc
  OF pivoted_data
  UNPIVOT)
  deptsal-<-->
  FOR saldesc-<-->
  IN (d10_sal, d20_sal, d30_sal, d40_sal).<-->
  )

  also assign the log count "Insert" on the tab corresponding to your INSERT statement, so that you know how many rows you insert into the table.

  I hope this helps.

  BUT remember that this feature is out in Oracle 11 g.

  I load this XML data file into a single table using an external Table. Could someone help me please with coding.

  Thank you

  Reva

  Could you please help me how to insert my XML content into that.

  Same as before, try a plain old INSERT:

  insert into xml_pecos

  values)

  XmlType (bfilename ('XML_DIR', "test.xml"), nls_charset_id ('AL32UTF8'))

  );

  But you'll probably hit the same limitation as with the binary XMLType table.

  In this case, you can use FTP to load the file as a resource in the XML DB repository.

  If the XML schema has been registered with the hierarchy enabled then the file will be automatically inserted into the table.

  Could you post the exact statement that you used to save the scheme?

  In the meantime, you can also read this article, I did a few years ago, it covers the XML DB features that may be useful here, including details on how to load the file via FTP:

• SQL * Loader vs external tables to a single file with several types of records (intercalated)

  I have a file of sample data (we will have the a 'true' at a later date and put in day after that) which includes a header, footer, and 5 types of records, that have different columns and lengths, noticed by the first two characters. The different types of records are not all together. On the contrary, some (in particular, two of these types in this example) are intertwined. I am currently working on a SQL * Loader configuration file when it was suggested that I use external tables. I know very little of either, then I would ask what is the best to use.

• charge of the external table

  I load a file .csv to table data.
  I tried to load it using EXTERNAL TABLES
  
  Is there a way to specify null in the external tables loaded if the column has no data queued (CSV) external loading
  Thank you

  Do you mean?

• Sqlloader Vs external Tables

  HII All,
  Currently, we use sqlloader. But now we are stuck to the top with a question. The problem is that in our production environment that they have installed customer sqlldr in the application server and the feed file in place in the Oracle server machine.
  
  We tried everything to stay with sqlloader but nothing works very well. I tried with ftp to transfer the file from Oracle server to the client machine, but we use the secure port it did not work.
  
  But this was easily accomplished using external table that the file is located in the server. But now I need to satisfy my clients by proving the external tables are relatively better.
  
  I have google for Sqlloader vs. external this debate.
  
  But I found no strong points supporting external tables.
  
  I had also gone through the following links
  
  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:6611962171229
  
  http://www.orafaq.com/Usenet/comp.databases.Oracle.misc/2007/02/13/0222.htm
  
  So please help me by providing some plus points and other links.

  Who would take more space on the database, while the external tables you can do anything as the data is read. External tables would seem better in this regard.

  And now, we are not concerned with all the functions for use in DEC.

  People argue with me if we use external tables, we need create objects 2 db (1 external and more temporary table) which is just 1 intermediate table if sqlloader.

  You only need the external table definition. If you create a temporary table with this depends on your needs and the need to have such a table "staged." Even if you did in SQL * Loader you would always create a staging table, if there is really no difference...

  External table = 1 table definition and no data loaded in the database
  SQL * Loader = 1 table and the data loaded into the database

  Also read that when the feed file is huge its better to opt for sqlloader as it can circumvent sql analysis by choosing a DIRECT approach. Isisnt it?

  External tables using SQL * Loader under the hood engine, so there is no real difference except where you want to keep your data (in the file, or load a copy first on the database). You can use the parallel with external tables to load using multiple threads, you can use the indicator append to load the data as in the direct approach of sql * loader.

  So, kindly suggest me which is the best approach in a long-term process.

  In the long term, the external tables are the best approach. They were introduced after SQL * Loader to provide an improved mechanism. If they were not better, Oracle would not have taken the trouble with them. They also have the advantage that the control of their use is on the database, i.e. no need to control files, no need to run a command-line utility, not two floors (loading then treatment) treatment.

  There is no real reason for the use of SQL * Loader everything but more, the strange unique circumstance where you need to download data from a client computer (which will raise the question why a client machine has data on it in the first place!)

• Facing many problems on the creation of directory and an external Table

  Question:
  
  The strange thing is that if you look at the question 10-b page 3-41, it says:
  (page 3-41 "Oracle Database 10g SQL Fund. II Vol.1")
  
  Merge the data into the EMP_DATA table that is created in the lab last in the data in the table emp_hist. assume
  EMP_DATA external table data corresponds to the EMP_HIST of table, update the email column
  table EMP_HIST to match the row in the EMP_DATA table. If a row in the EMP_DATA table is not
  match, to be inserted in the tables of EMP_HIST lines are considered as corresponding whenever his first and
  family name are the same.
  
  For me, this issue is built wrong. First of all in the last lab we have not been asked to create EMP_DATA. Secondly, EMP_DATA is empty.
  Thirdly, this question asks us to merge into the table EMP_HIST while EMP_DATA is empty.
  
  Table EMP_HIST currently copied data from the employees table. Structure EMP_HIST:
  
  FIRST NAME VARCHAR2 (20)
  LAST_NAME NOT NULL VARCHAR2 (25)
  EMAIL NOT NULL VARCHAR2 (45)
  
  Anway, I did the merger as follows:
  
  merge into e emp_hist
  with the help of emp_data d
  on (e.first_name = d.first_name)
  When matched then
  game update
  Select = d.last_name,
  e.email = d.email
  When not matched then
  Insert values (d.first_name, d.last_name, d.email);
  
  I get this error:
  
  Error report:
  SQL error: ORA-29913: error in executing ODCIEXTTABLEOPEN legend
  ORA-29400: data cartridge error
  KUP-04040: file emp.dat in EMP_DIR not found
  ORA-06512: at "SYS." ORACLE_LOADER', line 19
  29913 00000 - "error in the execution of %s legend".
  * Cause: The execution of the specified legend caused an error.
  * Action: Examine the error messages take appropriate measures.
  
  On the other hand, I said I'm going to try this:
  
  merge into emp_data d
  using e emp_hist
  on (d.first_name = e.first_name)
  When matched then
  game update
  d.last_name = select,
  d.email = e.email
  When not matched then
  Insert values (e.first_name, select, e.email);
  
  I get this error because the external table is final once its creation is as far as I know:
  
  Error report:
  SQL error: ORA-30657: operation not supported on external organized table
  30657.0000 - "operation not supported on external-organized table".
  * Cause: User attempted on the operation on an external table which is
  not supported.
  * Action: Don't do that!

  NOTE: I did my best, I've done everything I can do, but the problem persists. Help, please

  I'll mention all the steps that I made it clear...

  I gave scott the following grants:

  grant create any directory Scott;
  grant read on the directory emp_dir to scott;

  -----------------------

  1. create a directory and its been created successfully:

  create or replace directory emp_dir
  like 'F:\emp_dir ';

  Then I made just to make sure that my directory is recognized the following:

  SELECT *.
  OF dba_directories;

  I found the drive among the results...

  OWNER NOM_REPERTOIRE
  ------------------------------ ------------------------------
  DIRECTORY_PATH
  --------------------------------------------------------------------------------
  SYS EMP_DIR
  F:\emp_dir

  SYS SUBDIR
  D:\oracle\product\10.2.0\db_1\demo\schema\order_entry\/2002/Sep

  SYS XMLDIR
  D:\oracle\product\10.2.0\db_1\demo\schema\order_entry\

  ----------------------
  2. I created an external table emp_data (the script is given by the text book): successfully done

  drop table emp_data;

  CREATE TABLE emp_data
  (first name VARCHAR2 (20))
  , last_name VARCHAR2 (20)
  , email VARCHAR2 (30)
  )
  EXTERNAL ORGANIZATION
  (
  TYPE oracle_loader
  Emp_dir default DIRECTORY
  ACCESS SETTINGS
  (
  RECORDS DELIMITED BY NEWLINE CHARACTERSET US7ASCII
  NOBADFILE
  NOLOGFILE
  FIELDS
  (first name POSITION (01:20) TANK)

  
  , last_name POSITION (22:41) TANK
  CHAR POSITION (43:72) by email)
  )
  LOCATION ('emp.dat'));

  --------------------------------

  3. I went to drive F:\ to see if emp_dir file exist or not! I did not see it. I checked the files hidden, nothing. Anyway, I ignored and did step 4.

  "Anyway, I ignored him... "

  and so the rest of your problems. I do not see in the steps you told that acually you created a directory ("folder") named "\emp_dir" on your f: drive. Anything that you create the database will actually create this directory on the operating system. Uttering a directory in Oracle, uttering an external table in Oracle, don't create pointers to Oracle objects will assume just actually exists.

• Table data type

  Is there any equivalent data type to create a table inside a stored procedure or a package, and the table is only valid in the stored procedure or package.
  Something like this [http://www.developer.com/db/article.php/3414331/Using-the-Table-Data-Type-in-SQL-Server-2000.htm] what we have in sql server.
  
  I'm pretty new in Oracle world.
  
  Any help will be much appreciated.
  
  Thanks in advance.

  Yes... You can declare a record type in the package body

  TYPE rec_type () IS RENDERING
  NUMBER of col1,
  col2 VARCHAR2 (2 CHAR)
  ....
  );

  then simply declare a type of table top the record type

  TYPE tab_type IS TABLE OF THE rec_type;

  You can make statements within the body to keep it private, or in the spec to make it public

  It could be that useful...
