External Tables using Discoverer

I am mapping the contents of a complex query to an external table. I am mapping the SUM() of each field to the external table. BUT... when I create a workbook using that complex folder, Discoverer correctly uses the external table but when I look at the actual query that is generated it performs a 'GROUP BY' on the the summary table (i.e my external table) prior to doing the query that I originally wanted.
This is different than if Discoverer was managing the summary table. A very simple example is:
External Table Query
SELECT
SUM(alias_avar)
FROM
(select id, SUM(avar) alias_avar
FROM
summarytable
group by id)
Discoverer Managed
Select SUM(avar) from summarytable
Thank you in advance for helping me with any ideas or workarounds.

Just a word...I have had NO LUCK with Oracle9i external tables accessing network drive with Windows Server 2003 spk1.
I have read all the tips from Metalink and forums and nothing that works on Windows 2000 or NT work for 2003..Has anyone had any luck with this?
UNC or mapped letters..The best I could do was GIVE EVERYPERMISSION and create a SUPER users with ALL groups and still then all external tables could do was move it to the error folder with a OS errors saying it could not open the file. I have the same setup locally and it opens fine.
In fact UNC was the only way I could even touch the files..mapped drive letter did nothing ...

Can we take backup of external table using expdp

Can we take backup of external table using expdp, please suggest any doc.
thanks in advance.

@Fahd
About the ACCESS_METHOD parameter
-It's undocumented data pump parameter and it's should be used only when requested by Oracle Support
-It's purpose is to specify the loading/unloading method, not filtering object types during the export or import
-If this parameter is not specified,the Data Pump will automatically choose the best method to load or unload the data...
so,
the External Tables method
-Is used by the data pump if data cannot be moved in the default method to load/unload data ,
and that is direct path mode, or if there is a situation where parallel SQL can be used to speed up the data move even more

Problem with External Table using ORACLE_INTERNAL TYPE in 9i release 2

Hi,
I have tried to create an external table in oracle 9i release 2 using the following qurey:
CREATE TABLE emp_ext
ORGANIZATION EXTERNAL
( TYPE ORACLE_INTERNAL
DEFAULT DIRECTORY admin_dat_dir
LOCATION(admin_dat_dir:'emp1.dmp')
PARALLEL
AS
SELECT * from employees;
and getting the following error message
ORA-30657: operation not supported on external organized table
Please help me.
Thanks in Advance

As a matter of fact oracle 9i has two types of api for external tables one is oracle_loader and the other is oracle_internal which in 10g become oracle_datapump.
What my question is how can I use the other type in case of external table as we are doing in 10g? Do I need to run any script to enable this feature or is there any privillege issue?
I've given the read, write privillege to the user and the oracle user has read/write permission in os level on the location of the directory.

External Tables using SYSDATE

It's possible to use the external table with SYSDATE? Here is the create external table syntax I am using and it's not working.
create TABLE T_MASTER_EXT
CUSTOMER_NAME VARCHAR2(255),
AUDIT_TIMESTAMP DATE
organization external
type oracle_loader
default directory MY_DIRECTORY
access parameters
records delimited by newline
skip 1
fields terminated by ','
OPTIONALLY ENCLOSED BY '"'
lrtrim
missing field values are null
(CUSTOMER_NAME,
AUDIT_TIMESTAMP DATE SYSDATE))
location ('customers.csv')
reject limit unlimited;
Thank you.
H

Well, this discussion is rather academic since there is no facility to supply a virtual column with a default value of SYSDATE or anything else in an external table, but as I understand it "oracle_loader" external tables currently work like this:
1. You issue a query against an external table
2. The database starts an external loader process to open and read the file
3. The loader process parses the file contents and returns the results to your query.
Possibly I have oversimplified, but I just don't see where "The SYSDATE changes when the table is written" comes in. What process is this?
PS:
@VG - this thread would be a lot easier to read for those of us with small monitors if you could make that AskTom link a bit shorter ;)

Accessing The External Table using UIAPI and DIAPI

Hi Every One,
can any one tell me about , can we access the external table data that is created by using sql query externally using UIApi and DIAPI
Regards
Srinivas

Hi,
technically is it possible, but all inserts and updates have to be through query.
Note, that when you create tables from sdk, you can set more informations about fields than in sql query manager (for example subtype) - so you may have problem in binding data to matrix for example. So if you have table externally, you may work with, but this isn`t allowed by SAP (and I think that this case may be dangerous if you acces it in sdk). If you need to acces it on sql server side (own numbering, some stored procedure, ..) it will works safer, but it is not allowed as well.

Sqlldr flat file to external table using shell scripts

Hi,
Has anyone done this before? Please give me a hand.
Thanks!

Thanks Justin.
When do I need to create the external table EMP_STAGING ?
These are my steps so far:
- shell script to crate the flat file (but I need to change the table name to EMP_STAGING)
- use a script to call sqlldr to load the flat file into the external table
- then the script will call the MERGE sql script to merge the data from the external table into the database table
Am I on the right track?
In which stage should I create and drop the external table?
Thanks!

How to use remote directory for external table

Hi Folks,
I have 2 Oracle 11GR2 64 bit database installed on Win 2008 server as prod1 and prod2.
I have one directory created on prod1 server as EXT_TAB_DIR using the path as D:\OrsDWtest_dir .
I want to use this directory in Prod2 server and use external table using this remote directory.
I am able to access the Prod1 directory from Prod2 machine and also i have created Network map drive as Z drive pointing to that prod1 D:\OrsDWtest_dir directory. Also i checked read and Write permissions are there . I am able to create the external table but when i try to fetch the data i m getting below error ..
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-04040: file IOMM_20121213_060736.csv in EXT_TAB_DIR not found
now my doubt is this possible ? Can we use remote directory for External table ? or is there is there any alternative way to achieve same ?
Thanks & Regards,
Vikash Jain(DBA)

could you confirm the name and the existence of this file "IOMM_20121213_060736.csv" ?
same error like:

Accesing windows files using oracle unix external tables.

Hi, I'm trying to access files on windows2k using oracle external tables on unix:
Oracle server on unix: oracle ver. is 9.2.0.6 and OS is 5.8 Generic_117000-03 sun4u sparc SUNW,Sun-Fire
1. Created dir object on oracle unix pointing to windows path
2. created user
3. Assigned read and write privs on dir to user
4. created external table using dir step 1
5. select on external table
When I FTP the files into unix and recreate dir object, it works, but if I point dir object into windows path, it fails.
Is possible to do this?
Tks
GAP

Hi
The directory object must be accesible to your Database server, so if the Database is in unix you must create the directory in unix.
I don´t know software that allow unix systems to see a windows file system. Maybe windows can see unix from a samba server or NFS.

How to use External Tables

Hi, I want to know how to use external tables? The procedure i follow for SQL*Loader in my shell script is:
Call the sqlldr
Check return code
If return code = 2. get count of records from bad file and exit.
If return code != 0 and != 2 then exit as fatal error
If return code = 0 then continue.
But i don't understand how to use external table as it is not invoked and does not have a return code.

Hello,
What do you mean alogrithim, do you mean to invoke external table as you invoke sqlldr? You can generate external table script from sqlldr and use it to load data but you might have to modify the table name and datafile name . You can see if any bad file generated from sqlldr and if yes then you can generate external table (using sqlldr) or based on your bad file. May be if you can list what exactly you want in bullet points, then it will be easier to suggest you.

hope you would help me. i am greateful for that.

Arun,
Here are the things you could do.
1. You may want to specify a logfile in your access parameters using the command 'logfile'.
For example,
logfile 'info.log'. You could create the file in advance and provide appropriate permissions to the operating system user(In unix, I use the commands 'touch' and 'chmod').
2. You could specify the command
'NOLOGFILE' in your access parameters.
3. Provide permissions for the user to create files in the folder associated with the directory object 'aps_jul'.

(I only want to give USER2 access to two of the four columns.)As you have demonstrated, I guess the view approach only works for database tables. External tables are actually files on the file system. Even through OS, it is not possible to grant READ/WRITE access to only part of the file. The access is for entire file. An "External Table" is just a "wrapper" provided by oracle (using data cartridge) to allow user to be able to access the file as a "table". So it can definitely not do something that underlying OS can not do.
p.s. In fact, oracle does not even allow to edit data in external tables using SQL.Why not just make a second external table (only including the 2 columns you need) and grant select directly on that to the user. I know you say "views only" but there's an exception to every rule ... just because it's called a table doesn't make it so. You could argue an external table is nothing more than a fancy view.
Worst case, make a view on top of the second external table.

Error when loading from External Tables in OWB 11g

Hi,
I face a strange problem while loading data from flat file into the External Tables.
ORA-12899: value too large for column EXPIRED (actual: 4, maximum: 1)
error processing column EXPIRED in row 9680 for datafile <data file location>/filename.dat
In a total of 9771 records nearly 70 records are rejected due to the above mentioned error. The column (EXPIRED) where the error being reported doesn't have value greater than 1 at all. I suspect it to be a different problem.
Example: One such record that got rejected is as follows:
C|234|Littérature commentée|*N*|2354|123
highlightened in Bold is the EXPIRED Column.
When I tried to insert this record into the External Table using UTL_FILE Utility it got loaded successfully. But when I try with the file already existing in the file directory it again fails with the above error, and I would like to mention that all the records which have been loaded are not Ok, please have a look at the DESCRIPTION Column which is highlightened. The original information in the data file looks like:

Create an external table based on an XML file

Hi ,
I am trying to create an external table based on XML file .Is it possible to do in OWB ?If Yes .Can someone please let me know the same .
I was successfully able to create an external table based on a flat file which is of the extension *.txt.
I was even able to load an XML file to a normal
table .How do we do it to an external table?
Thanks,
Manjula

Hello Manjula,
Is it possible for you to spare sometime to list down the steps to be followed for creating External Table using flat file *.txt?
I am trying to do it but not getting through it.
Thanks in Advance,
Ripesh

In External Table ...

I have created external table using that syntax, but while i select value from that table i am getting the following error.. "Source of TYPE SYS.ORACLE_LOADER is not available" what can i do for that... i have defined the directory, then what can i do next..please urgent....
thanks
Raj

Source of TYPE SYS.ORACLE_LOADER is not availableDid you maybe query the external table via a tool such as TOAD or PL/SQL Developer, the query failed, and the tool prompted you for whether you wanted to view the source of the error? (Wild guess.)
