External table of hourly load

Hello

How can I plan to load the external table?

I have the external table and the target table, so I want to plan the following statement:

Insert into target_table as
Select * from external_table

What is the best approach? To create a stored procedure and the calendar?

Thank you

Difference between external tables and sql * loader
Hello

Could you please tell me the difference between
tables external and sql * loader

I have serached on the net but did ' get correct idea

Please help me
1 SQL LOADER can be run on the network (from any client computer), external tables can't

2. return to the Oracle 9, external Tables could not load CLOB/BLOB (Oracle10 changed it)

3 oracle 11 external tables have preprocessor, which is pretty dam characteristic cool - running essentially any OS command e.g. decompress before external table run. What's even better is the fact that the result of the operating system command is the source of the outer table, which means that there are no required temporary file (unzip the tracks and the output is the source of the external table). There are several ways to great use this - look at my blog for samples rare http://jiri.wordpress.com/2010/01/19/no-more-unix-scripts-in-11-2/

4. as long as the 009 stressed, filed external load anything, they show just. Think of it more as load on request - it's great if you have old files archived and one or two users what to see content once a while

5. external tables require no user access to the operating system, it is oracle environment pure - this may seem minor but for me it's huge. The fact that the ETL needs no special unix, no control file command and uses the simple SQL and DDL is nice and important

6. external tables can load more text files, Oracle export dump files can be loaded, perhaps in the future more formats will be supported (hopefully all right excel format?)

now the same thing to kill the myth - the TWO are EXACTLY the same when it comes to speed, I would actually drive of the external tables before will be faster because sql loader is old technology oracle doesn't really develops more

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.

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

Alex
@OP,
What version of Oracle are you using?
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...
I have a few records rejected, and all these folders contain the last field AMOUNT with scientific notation

How can we not consider a field missing for external tables
My to Oracle. East of 10 gr 2
I created an external table using the following syntax:

create the table ext_table
(a number (5),)
b number (5),
c varchar2 (1000))
external organization
(type ORACLE_LOADER
FLAISTD default directory
access parameters (records delimited by newline
fields ended by "#".
(a char (5),
b tank (5),
c char (1000)))
location ("file.csv")
);

My problem is the following. I have a file. XLS I save as a file. CSV sometimes any line of the file. XLS for young woman of the last column and so in my folder. CSV, I can have something like this:

123 123 # #xxx
456 #456

and when I try to execute a select * from ext_table, I get an error because he expects a missing field.
How can I do? 'Say' in the table create above something alert who could miss the last field?

Thanks in advance!

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
  ACCESS PARAMETERS
  (
   RECORDS DELIMITED BY '
' CHARACTERSET 'UTF16'
  FIELDS TERMINATED BY ','
  )
  LOCATION ('dump.csv')
)
REJECT LIMIT UNLIMITED;
```

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.

Yes, it's really a good point, but can be achieved once the data has been pumped into staging tables.

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!)

Add 'jump 1' to the definition of the external table after...?
I created several external new definitions from file table definitions, but when the 'production' files have been created have now a header row at the top which should be ignored for not to be taken as data.

Is there a way to "Edit" the file or definition the definition of the external table to add the mention "jump 1' without having to recreate the definition file to re-import the file and then recreate the external table?

I remember there is a place in the file import process that asks the number of lines to skip.

Thank you very much!!

-gary

P.S. This is indeed an OWB 10.1.0.4 environment but I guess he would hold even to 11g as well. :-)
Hi Gary,.
It seems OWB10g R1 does not setting property to jump (for the creation of the external table or SQL * Loader control file).

But for OWB10g R2 and later it is possible:
(1) in the Properties window of the file on the general tab, change "number of lines to skip.
(2) synchronize the corresponding external table and deploy

Kind regards

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:

https://odieweblog.WordPress.com/2011/11/23/Oracle-XML-DB-a-practical-example/

And documentation of the course: http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb06stt.htm#ADXDB4672

But if I see the file I saw that BMW.

My question is, in this case the external table loading must fail right? Why is this it is to load data in DB?

Do you have this file begin life on windows, and then are transferred to * nix to serve an external table? If so, which explains a lot. Windows is the standard record delimiter x '0d0a' (Chr (13) 10) On * nix, it's just x '0A' (10. When the process of loader is scanning for record delimiter he's just looking for the '0A' x and x'd 0' gets included in the data.

Two solutions-

1 - Make sure that the data file is transferred so that the Records delimiters are converted. It's supposed to to happen with ascii ftp mode, but this week I saw several examples in the House of it does not.

2. attach your table definition external to seek the delimiter of actual recording instead of the default value of the operating system. == RECORDS DELIMITED BY X '0D0A '.

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.

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.

Below is a table of external work that works, but cut all entries after 4000 bytes. How is it is possible to directly load the data into a clob column? All I've found are descriptions where I have a clob-file by file.
Any help is appreciated

And what did you expect if you define the field source and target column as 4000 characters?

Try this:
```
CREATE TABLE tst_table
 (
   txt_line CLOB
 )
 ORGANIZATION EXTERNAL
 (TYPE oracle_loader
    DEFAULT DIRECTORY tmp_ext_tables
    ACCESS PARAMETERS (
       RECORDS DELIMITED BY ']]'
       FIELDS (txt_line CHAR(32000))
    )
  LOCATION ('test5.log')
 )
REJECT LIMIT 0
;
```

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.
