• The external table, question of double data type

  Hello

  We are the migration of 11g CL8MSWIN1251 to 12 c UTF8.

  Now, we test the exteranl tables and that we've met the problem below.

  We have a binary file (little endian) with fields of type double.

  In 11g, it is very well analyzed, but in 12 c obtained ' ORA-29913: error in the execution of legend ODCIEXTTABLEFETCH"" "".

  In the Oracle docs, I found this paragraph, the last sentence of worries.

  The DOUBLE clause indicates that the field is the same format that the C language, data type DOUBLE on the platform where the access driver is running. Use of the DATA IS {BIG |} LITTLE ENDIAN clause} can cause data to byte - swap before it is stored. Such data may not be portable between certain platforms.

  Here is an example of a test that works on 11g, Oracle Enterprise linux 6.5. And get the error above 12 c 7.1 OEL

  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.

• External table. How to load numbers (scientific and decimal notation format)

  Hi all, I need to load within a records in the external table that contain 7 fields. The last field is called AMOUNT and he has represented in some documents in decimal, in other documents in the format of scientific, notation for example, below:
  
  CY001_STATU; 2009; Jan; 11220020GR;' 03900; CYZ900; -9, 99999999839929e-03
  CY001_STATU; 2009; Jan; 11200100;' 60800; CYZ900; 41380,77
  
  The external table script is the following:
  
  CREATE TABLE HYP_DATA
  (
  COUNTRY VARCHAR2 (50 BYTE)
  YEAR VARCHAR2 (20 BYTE).
  PERIOD VARCHAR2 (20 BYTE).
  ACCOUNT VARCHAR2 (50 BYTE),
  VARCHAR2 (20 BYTE) DEPT,
  ACTIVITY_LOC VARCHAR2 (20 BYTE),
  AMOUNT VARCHAR2 (50 BYTE)
  )
  EXTERNAL ORGANIZATION
  (TYPE ORACLE_LOADER
  THE DEFAULT DIRECTORY HYP_DATA_DIR
  ACCESS SETTINGS
  (RECORDS DELIMITED BY NEWLINE
  BADFILE ' HYP_BAD_DIR': ' HYP_LOAD.bad '.
  DISCARDFILE ' HYP_DISCARD_DIR': ' HYP_LOAD.dsc '.
  LOGFILE ' HYP_LOG_DIR': ' HYP_LOAD.log '.
  SKIP 0
  FIELDS TERMINATED BY '; '.
  MISSING FIELD VALUES ARE NULL
  REJECT ROWS WITH ALL FIELDS ARE NULL
  (
  Tank of 'COUNTRY ', he said.
  'YEAR' tank,.
  Chariot of the "PERIOD."
  Char 'ACCOUNT ',.
  'DEPT' tank,
  "ACTIVITY_LOC," tank
  Char 'AMOUNT. '
  )
  )
  LOCATION (HYP_DATA_DIR: 'Total.txt')
  )
  REJECT LIMIT UNLIMITED
  NOPARALLEL
  NOMONITORING;
  
  If, for the field AMOUNT, I use VARCHAR (see above) data type, the table is loaded but I have some records rejected, and all these folders contain the AMOUNT in the field with scientific as notation:
  
  CY001_STATU; 2009; Jan; 11220020GR;' 03900; CYZ900; -9, 99999999839929e-03
  CY001_STATU; 2009; Feb; 11220020GR;' 03900; CYZ900; -9, 99999999839929e-03
  CY001_STATU; 2009; Mar; 11220020GR;' 03900; CYZ900; -9, 99999999839929e-03
  CY001_STATU; 2009; Dec; 11220020GR;' 03900; CYZ900; -9, 99999999839929e-03
  
  All records with a decimal NUMBER are loaded correctly.
  
  So my problem is that I NEED to load all the records (with the comma and the scientific notation format) together (without the rejected records), but I do not know what data type should I use for the field AMOUNT...
  
  Someone has an idea?
  Any help would be appreciated
  
  Thanks in advance

  Just Cut the dough of your script and example woked FINE for me.

  However my equation is... An external table will all LOAD data or not at all. How did you validate/conclude that...

• 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.

• 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
  
  Simon Gadd
  Oracle 11g 11.2.0.1.0

  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

    FIELDS TERMINATED BY ','
    )

  )

  It lies in the part parameters access and what the SYSDATE part?

  I misread your question. External tables do not support the built-in functions. And there is no need for this. Just use them to select in the external table. So get rid of the date_update column in the external table:

  create table ext_ID_REQ_table (
  account varchar2(5),
  email varchar(85)
  )
  
  organization external (
  type oracle_loader
  default directory user_dir
  access parameters (
  records delimited by newline
  badfile ID_REQ_bad_dir:'ACCT_EMAIL%a_%p.bad'
  logfile ID_REQ_log_dir:'ACT_EMAIL%a_%p.log'
  fields (
  account position(1:5) char(5),
  email position(6:90) char(85)
  )
  )
  location ('test.txt')
  )
  reject limit unlimited;
  

  Assume that the test.txt file is:

  A    [email protected]
  B    [email protected]
  C    [email protected]
  

  In select now use sysdate right:

  SQL> select  account,
    2          email,
    3          sysdate date_update
    4    from  ext_ID_REQ_table
    5  /
  
  ACCOU EMAIL                                                                                 DATE_UPDA
  ----- ------------------------------------------------------------------------------------- ---------
  A     [email protected]                                                                               15-JUN-10
  B     [email protected]                                                                               15-JUN-10
  C     [email protected]                                                                               15-JUN-10

• Direct load in external tables

  Can we use direct load in external tables? or set DIRECTLY in the external table script?
  
  Thank you.

  Thank you.

  N ° why? Because an external table does not load data. It's more like a pointer and an instruction how to read a file.

  The big difference between SQL Loader and an external table, SQL Loader is actually two things.

  (a) it reads a file from the file system
  (b) it inserts these values into a table in the database.

  An external table only one).

  However, you can do a quick insertion of this external table in an actual database table so that is sought.

  insert /*+append */ into myRealTable (colA, ColB, colC)
  select  * from myExternalTable
  

  Append it and perhaps also the parallel indication will be close to a direct path insert.

• Several flat_files through the external table with only the common columns of loading

  Hi, I have 50 flat files and each of them have some columns (fields) common and I need to load only the fields that are common to an external Table. Is any chance to do it with education unique external table. Or I need to load all flat_files at separate tables and then with the ETG and UNION load them only one table.

  If the page size for all the files are different, I think that your only option would be to define different external tables and create a view that joins all the.

• Create an external table to import csv to dynamic action

  Hello
  
  I'm trying to import data from a csv file into a table. The csv is located on the server and I try to do an external table to copy its contents to the master data table.
  I can't even save the code, without this error:

• How replot a table using plotXY without creating a new parcel?

  I want to replot continually a table using plotXY without increment the name of the parcel. Is this possible?

  Whenever I call plotXY a new path is created. For example, the first time that plotXY is run, I get a marked route Plot1 (parcel number 1). The second time I call plotXY, I get a parcel named Plot2 (parcel number 2) and so on. But I want to draw the same picture several times that I've added more data to it. And I want the name of the parcel to be Plot1 every time.

  I know that I can change the name 'Plot1' attribute after the call to plotXY. But I feel that somewhere in the internal parts of the graph I'm ever increasing utilization of certain resources. I'll be Replot the table several hundred thousand times so I don't want to run out of memory or something.

  So my question is this, is it possible to re - initialize a graph to its original state before you run the plotXY?

  Do not confuse the name of the parcel and manage the resources allocated to the curve. If you delete all the plots in the graph with DeleteGraphPlot () then draw a new curve, you should have 'Track 1' under the name of the plot, but you will get a continuously raise the handle of the plot; This does not assume that you are summarizing additional resources whenever you draw on the graph, the graph simply never reuses draw handles associated with deleted locations.

  In your case, you can also try a different approach:

  1. Use a graph of the band instead of the chart: if possible you will avoid the problem of more names of conspiracy and will reduce the program activity that you will draw only new points in every race
  2. Only new field points with PlotXY showing only the first parcel in the legend: you will need to keep track of array index, already mapped out so that if you have traced up to array [index] to date, you will draw array [index] to array [newindex] on the new iteration
