• Using the external table error

  Hi all

  This is the first time I use the external table for loading the data.

  I did these steps

  In the D:\sqlloade folder, I have my text file containing data example.txt

  I ran these queries

  CREATE OR REPLACE DIRECTORY  ext_tab_data AS 'D:\sqlloader';
  
  

  Directory created

  CREATE TABLE fxops.t_ext (
  t number
  )
  ORGANIZATION EXTERNAL (
    TYPE ORACLE_LOADER
    DEFAULT DIRECTORY ext_tab_data
    ACCESS PARAMETERS (
      RECORDS DELIMITED BY NEWLINE
      FIELDS TERMINATED BY ','
      MISSING FIELD VALUES ARE NULL
      (
       t number
      )
    )
    LOCATION ('sample.txt')
  )
  PARALLEL 5
  REJECT LIMIT UNLIMITED;
  
  

  create table

  When I tried to create a view on that table, he throws an error

  CREATE OR REPLACE VIEW fxops.t_view  AS
    SELECT *
    FROM   fxops.t_ext;
  
  SQL Error: ORA-06564: object EXT_TAB_DATA does not exist
  06564. 00000 -  "object %s does not exist"
  *Cause:    The named object could not be found.  Either it does not exist
             or you do not have permission to access it.
  *Action:   Create the object or get permission to access it.
  
  

  Sign in, and then run this:

  Select HOST_NAME from v$ instance;

  is this the same hostname that you are connected?

• Timestamp of reading using the external Table

  Hello
  I have a data file that looks like

  I am trying to use an external table. But I always get an error trying to read the fractional part (ie the last 6 digits).
  The code is:

• Error importing CSV files with "hidden" characters using the external Table

  Hi people
  
  Bit of a strange here.
  
  Well, we are accustomed to the use of the external Table method to load data from CSV files in the database, but a recent event presented us a problem.
  
  We have received some CSV files that "look like" regular CSV files, but Oracle will not load them.
  
  When we looked at the CSV using VIM on a UNIX machine, we saw the following characters 'hidden' between each regular character in the file.

  ^@

  If a string that looks like this when opened in Excel/Wordpad etc.

  "TEST","TEXT"

  Looks like this when exmained with VIM

  ^@"^@T^@E^@S^@T^@"^@,^@"^@T^@E^@X^@T^@"

  Has anyone encountered this before?
  
  Thank you very much

  Hi Simon,.

  ^ @ represents the ZERO character (0x00).
  So, most likely, you have a file encoded in Unicode.

  You need to specify the character set in the record specification (and if necessary the byte order mark), for example:

  CREATE TABLE ext_table
  (
    col1 VARCHAR2(10),
    col2 VARCHAR2(10)
  )
  ORGANIZATION EXTERNAL
  (
    TYPE ORACLE_LOADER
    DEFAULT DIRECTORY dump_dir
    ACCESS PARAMETERS
    (
     RECORDS DELIMITED BY '
  ' CHARACTERSET 'UTF16'
    FIELDS TERMINATED BY ','
    )
    LOCATION ('dump.csv')
  )

• mapping using the external table error.

  I'm trying to create a map using an external table.
  I'm testing a simple column to column mapping. As simple as you could possibly get.
  Can I deploy the mapping without errors, but when I try to run the map, I get a
  ORA-06564: EXT_DATA object does not exist
  
  I created my external to oracle using the ext_data directory. I can see the data without any problem in TOAD or SQLPlus.
  
  I tried to create a place called ext_data and it helps this creation, but I still get the same error.
  
  Any thoughts?

  Hi Dan

  You must deploy the EXT_DATA connector (to be deployed as a Directory SQL) that is created under the location of Oracle used for your external table module is in.

• The group using the external table name

  Hello
  
  I used the following link and I was able to create groups based on these steps. However I have a question, in the initialization block SQL SQL has a variable name,

• Problem with the format of the external tables

  I am using the external Tables feature in Oracle.
  
  The code I am using currently to create my table is (I cut down the list of fields for clarity).

  create table EMP_EXTERNAL2
  (HIREDATE DATE )
  organization external
  ( default directory EXT_TABLES
  access parameters
  ( records delimited by newline
  fields terminated by ',')
  location ('EMP.CSV') )
  
  REJECT LIMIT 0
  ;

  But I get rejected folders when I select in the table due to the format of the HIRE date. The examples I've found suggest using a date format, change the code to:

  create table EMP_EXTERNAL2
  (HIREDATE DATE 'mm/dd/yyyy')
  organization external
  ( default directory EXT_TABLES
  access parameters
  ( records delimited by newline
  fields terminated by ',')
  location ('EMP.CSV') )
  
  REJECT LIMIT 0
  ;

  When I run this I get ORA-00907: lack the closing parenthesis. What I'm doing wrong here (I'm under the code in SQL Developer incidentally)?

  Hello

  Try this: -.

  create table EMP_EXTERNAL2
  (HIREDATE DATE )
  organization external
  ( default directory EXT_TABLES
  access parameters
  ( records delimited by newline
  fields terminated by ','
  (
  HIREDATE DATE 'MM/DD/YYYY'
  ))
  location ('EMP.CSV') )
  
  REJECT LIMIT 0

• The external Table storage

  Since data is stored outdoors, and the definition that is stored inside, it means that a the table structure of the outer table is stored in the database as well (or a virtual table based on the definition of the external table...)

  I'll hit the ORA-DOCS again once, back in the external tables read tonight on them 2 or 3 sources and it is not quite clear whether real data with structure exists outside the database or an internal table set (and stored) retrieves data from an outside source.

  Since data is stored outdoors, and the definition that is stored inside, it means that a the table structure of the outer table is stored in the database as well (or a virtual table based on the definition of the external table...)

  The 'definition' you refer to IS the structure of the table; they are one and the same. There is no 'table' stored in the database using space or storage. When a query on an external table is executed, the data source is read.

  
  I'll be hitting the ORA-DOCS up again, just got back into external tables tonight reading up on them from 2-3 sources and it is not quite clear if an actual data with structure exists out of the database , or an internally defined (and stored?) table draws data from an outside source.
  

  I suggest you that start with the documentation of Oracle - including the ground provided the link to:

  If any "metadata" are stored outside the database depends on if the file that is outside of the database was produced by Oracle using the robot UNLOADING discussed in this doc

  Unloading of data using ORACLE_DATAPUMP Access driver

  To unload data, you use the ORACLE_DATAPUMP driver access. The stream that is discharged is in a proprietary format and contains all of the data column for each row being unloaded.

  A discharge operation also creates a stream of metadata that describes the content of the data stream. The information in the metadata stream are required to load the stream. Therefore, the metadata stream is written to the file data and placed before the data stream.

  If YOU provide data/files, then you MUST provide it in the format expected by the external table statement. You can, if you wish, use a preprocessor to convert ANY file (zip, encrypted, etc.) in the required format.

  For YOUR files, you can the metadata stored in the same file, or elsewhere, if you choose, but Oracle will have NO knowledge of this fact and not will NOT be involved in the transformation or read any of the metadata that you provide. Your preprocessor must remove all these metadata and ONLY provide data in the format appropriate for Oracle to use.

  If the file was produced by the process of UNLOADING Oracle then it will include metadata that Oracle WILL read, use, and remove as says this quote from doc above. These external metadata is added to the real external table definintion/metadata stored in the dictionary.

  You can use a column in the external table that contains all characters and a view that selects in the outer table, limiting the lines based on the length of the column that contains all characters, such as shown below.  You can create a separate view for those! = 87 if you want a list of releases.

• When to load the external table condition

  
  Hello

  Is my version of db: oracle 11g

  I have a 6 gig csv file.

  I divided it several 15 MB csv files.

  But only the first csv file has header (with column headers).

  I have to load each of these files into a target table.

  I created an external table with jump 1.

  But how can I substitute jumping 1 for other csv files.

  Is there a way I can do it in the external table definition.

  I can't merge the split csv files and run as one big file. So I don't hv this option. Please advice.

  You should be able to use the LOAD WHEN clause to exclude a line based on the contents of a field. Or the other

  WHEN LOAD 1 / 2! = "ID".

  or, if the bonds are quoted,

  WHEN LOAD 1:4! = « « ID » »

  or you can always add a list of fields to your specifications and the names of the fields in the reference LOAD WHEN the condition instead of using an absolute position.

  Don't know if you saw my comments on the use of the tail command before you replied, but if the break-up of the file is part of your project of automated process, and then deleting the header row could certainly be integrated into this process if your on a unix platform and using the split command to split the file.

  Kind regards

• Portege R600 - how to use the external monitor on the docking automatically

  Hi - I just got a new Portege; R600-102. It's a great machine - very light and fast.

  I connect to a Slim port replicator to the office and I wish I could anchor and automatically use the external monitor without opening the laptop. Can someone point me in the right direction on how to do it? This process has worked well on my recently retired Dell X 300.

  More precisely:
  # I have the laptop closed Portégé and standby mode
  # I anchor in the Slim Port Replicator (SPR)
  # I press the button 'on' on the SPR
  # I see the message "recovery windows" and the bars of the countdown on the external monitor. (So I know it's connected and you can see the external monitor)
  # The laptop turns on but use the laptop screen (private) LCD
  # I have to open it and manually tell it 'out to watch.
  What can be automatically?

  Thanks for the tips.

  Hi mate

  Of course, you can close the lid when the laptop is connected to the external display.

• Measurement error of the County of edge by using the external sample clock

  Hello

  I'm trying to measure the number of edges (rising) on a square wave at 5 kHz with a generator function on a device of the NI PCIe-6363. I configured a channel of County of front edge of counter at the entrance of the PFI8 device. I use an external sample clock that is provided by the output of the meter of a NI USB-6211 housing channel. If I acquire for 10secs then ideally I would expect to see a total of 50000 edges measured on the meter inlet channel. However, my reading is anywhere between 49900 and 50000.

  When I use the internal clock of time base to measure the edges, the measure is accurate and almost always exactly 50000. I understand that when you use the external sample clock, the precision of the measurements is subject to noise level of the clock signal. However, I checked the clock signal is stable and not very noisy. Any reason why there is an error of measurement and how tolerance should I expect when using an external sample clock compared to when you use the internal time base clock?

  Also, what is best clock Frequency (with respect to the frequency of the input signal) when using an external clock?

  Thank you

  Noblet

  Hi all

  Thanks for all your sugggestions. I was using an input signal with a function generator which had a range of 8V. It turns out that the reduction of the amplitude to 5V solves the problem. I was able to get accurate numbers with the 6211 external clock.

  Thank you
