Is 2 external table allowed for same table in the same db.

Hi,
Is it possbile to have 2 external tables in a database for the same table? The intention is to run the loading in parallel.
I would be highly grateful if someone can answer my query?

Error while loading data into External table from the flat files

HI ,
We have a data load in our project which feeds the oracle external tables with the data from the Flat Files(.bcp files) in unix.
While loading the data, we are encountering the following error.
Error occured (Error Code : -29913 and Error Message : ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-04063: un) while loading data into table_ext
Please let us know what needs to be done in this case to solve this problem.
Thanks,
Kartheek

SD - Manual entries allowed for item category in the Sales Order

Hi experts,
please do you know any OSS note related to SD, in order to increase the number of Manual entries allowed for item category in the Sales Order (table T184)?
Thank you very much
Andrea

Hi,
I searched OSS notes and did not find any OSS Note related to add more than 11 Manual Item categories or append T184 Table.
Has any found solution for this, will this be a CORE MOD.

Any way to check for errors in an external table besides the log?

For example if you have an external table where a column is defined with a CHAR(1) but when you run a SELECT on it, the mapping comes up with trying to put a CHAR(2) into that single space. The only way I'm aware to see if something is wrong is to check the .log file. Is there any other way to check for an error message or count?
I'm mounting external tables and copying data over to a 'holding' table to be able to work on the data before it's moved into the actual production table with PL/SQ code. If the stored proc can determine what rows are bad or missing or even that there just are some rows with problems then hand back to the app, it would greatly improve things.
Thanks.

No other way than to check for the existance of a .bad file, then have a look see at the .log then?

Using users from an external table in the BI Publisher add-in for Word

After installing the BI Publisher add-in in Word, I find that I can connect to BI Publisher (http://hostname:9704/xmlpserver) only using IDs that are defined within WLS. I'm using an Oracle database table and external authentication to get my users logged in to the Answers environment, and they use the BI Publisher features of Analytics as well. But if I try to connect from the add-in to xmlpserver as one of those externally authenticated users, it fails.
Do I have to create new users in WebLogic Security for those folks who need to build BIP templates in Word? If not, how can I get the add-in to recognize and use the external table authentication?
I'm in 11.1.1.6.2 BP1, but I've noticed the problem for a long time, possibly back to 10g.

As you probably noticed, your formulas won't import into Project Siena - only the data.
I've created a sample application for you to demonstrate how you create formulas in Project Siena.
Here's the link to the project:
https://onedrive.live.com/redir?resid=D64FC13017F614FD!47783&authkey=!AN3UxGDTP1vNbbU&ithint=folder%2cjpg
In this example, I'm doing the heavy lifting on the Calculate button.
Here's what I did to create the project.
I added two input text boxes for height and weight
I added a calculate button.
I added a label to display the result. In the Default Text I added
BMI which is a context variable. I could have called it BMIResult - it's up to you.
Here's the formula for OnSelect of the Calculate button:
UpdateContext({BMI: Round((Value(txtWeight!Text) / Value(txtHeight!Text * txtHeight!Text)), 2)*703})
Note: If you haven't done so already, click 'Express View' in the lower right hand corner to see the properties.
UpdateContext is a formula that is used to change results - in this case the variable, BMI.
I used the Round function so it displays 2 digits for the decimal.
I used the Value formula to convert the input boxes to numbers.
This should get you started in the right direction - let me know if you need further explanation.
One more thing to add - when creating a context variable, you will see a yellow exclamation mark until you have a formula that references it.

Either need ability to edit PS layer style in FC or allow for update check to the .psd file

There is not much control over look in FC of imported .psd file. So please allow for update import some how.

I think if you poll users you will find Designers and Artists are most familiar and comfortable with Photoshop than Illustrator. That is one of the reasons I never upgraded or pushed to get the latest illustrator. Illustrator seems to not be as easy to use as Photoshop or AfterEffects. I am hoping that CS4 is identical to Photoshop for me to even consider to upgrading. I only use illustrator for the vector brush storkes it can do to paths, or to open a vector file and instantly copy and paste it as smart object into Photoshop.
I also do not understand why every element in Photoshop can't behave like in AfterEffects. In AfterEffects every value is re-editable and stackable. Thus no need to come up with new workflow of converting to smart object as everything is smart.
To me it seems like software development groups are siloed from each other at Adobe. I hope I am proved wrong and roundtriping become real for Photoshop as well as Illustrator.

Do I need an external voltage converter for Spain or is the white box on the end of my MacBook Air cord enough?

Do I need an external voltage converter for my trip to Spain, or is the white box on the end of my MacBook Air power cord enough of a converter?

Thank you very much! Apple telephone support couldn't come up with the answer. I won't haul that heavy external voltage converter to Spain. It weighs a lot!

I am running Mac OSx Lion 10.7.2. My problem is I can't search on an external network server for a file with the finder toolbar anymore. Nothing shows up and it will not search. I was able to in snow-leopard and am no longer able to w. Lion. Suggestions?

I am running Mac OSx Lion 10.7.2.
My issue is that I am not able to run a search in the finder toolabar on a network server. No files show up nor does it search on the server anymore. I was able to run the search in snow-leopard and am no longer able to do so with Lion. Is there a preference I can change or some kind of app or program I can download that will help me with this issue? This is extremely problematic for me as I am searching for files all day everyday. Thank you!

Hello,
It isn't the fw in Network you want o use or look at, that's for something completely different.
My first suspect is the Power Adapter on the LaCie has gone.
At the Apple Icon at top left>About this Mac, then click on More Info, then click on Hardware>Firewire, what is listed there?
Reset the Firewire bus
If your Firewire or USB isn't recognizing any device. A solution which has worked for some whose hard drive became invisible in 10.4 was simply to follow these four steps to reset the Firewire/USB bus:
1. Shut the machine down.
2. UNPLUG the power lead to the computer and any firewire/USB drive or devices.
3. leave it for 10 minutes.
4. Connect back up and reboot.

Network location for external table's file

Hi,
I am trying to import data from a csv file in oracle 10g database. I can successfully upload data from a csv file located on server itself using external table. But when I redefine directory object on a folder on network location, it doesn't work. Is that a limitation with external tables to access data from a file on network location.
Any clarifications and suggestions would be highly appreciated.
Thanks,
Aniket

Hi Nicolas,
I created a directory object pointing to a folder on a system(Other than Oracle 10g server) in the network. This folder is shared and can be accessed from the Oracle 10g server. When I create an external table with the default directory as the shared folder it couldn't read the csv file from that folder ( Shared folder on another system).
But when I redefined the directory object on a local folder which was on Oracle 10g server, it could read from csv file in the local folder using external table.
My understanding is using external tables, one can only read files that are on the local machine i.e. Oracle 10g server and not on a different system.
Please correct me if i am wrong. Any further suggestions would be highly appreciated.
Regads,
Aniket

REJECT LIMIT UNLIMITED
In these Table Some Columns having the Special Character like 'new line feed' ie it looks like a square symbol in my database.
How can i avoid that kind of special symbols while creating the External Table.
I tried with the TRIM command also with External Table Scripts but it doesn't works.
please help me in this issue.

Hi,
Use Substr or Replace functions on them.

Csv file processing using external table

Dear All,
Our database is oracle 10g r2 and OS is solaris
We would receive csv files to a particular directory on server each day.
File Format look like:
H00,SOURCE_NAME,FILE_CREATED_DATE
RECORD_TYPE,EMP_ID,EMP_NAME,EMP_DOB(DDMMYYYY),EMP_HIRE_DATE(DDMMYYYY),EMP_LOCATION
T00,RECORD_COUNT
EMPLOYEE TABLE STRUCTURE
EMP_ID                   NOT NULL    NUMBER ,
EMP_NAME            NOT NULL    VARCHAR2(10) ,
EMP_DOB                                  DATE,
EMP_HIRE_DATE   NOT NULL     DATE,
EMP_LOCATION                VARCHAR2(80)
Sample File:
H00,ABC,21092013
"R01",1,"EMP1","14021986","06072010","LOC1"
"R01",20000000000,"EMP2","14021-987","06072011",""
,***,"EMPPPPPPPPPPP3","14021988","060**012","LOC2"
"R01",4,4,"14021989","06072013",
T00,4
we need to validate each record excluding header and trailer for:
DATATYPE, LENGTH,OPTIONALITY, and other date validations such as EMP_HIRE_DATE can not be less than EMP_DOB
In case of any data errors we need to send a response file for corresponding source file.
we have predefined error codes to be sent in the response file.
ERR001    EMP_ID can not be null
ERR002    EMP_ID exceeds 10 digits
ERR003    EMP_ID is not a number
ERR004    EMP_NAME   has to be text
ERR005    EMP_NAME length can not exceed 10
ERR006    EMP_NAME   can not be null
ERR007    EMP_DOB is not a date
ERR008    EMP_DOB is not in ddmmyyyy format
ERR009    EMP_HIRE_DATE is not a date
ERR010    EMP_HIRE_DATE is not in ddmmyyyy format
ERR011    EMP_HIRE_DATE can not be null
ERR012    EMP_LOCATION    has to be text
ERR013    EMP_LOCATION   length can not exceed 80
ERR014    EMP_HIRE_DATE can not be less than EMP_DOB
ERR015    Field missing in the record
ERR016    More number of fields than allowed
1.Do I need to create external table before processing each file.(EMP1.txt,EMP2.txt)?
2.How to generate these error codes in case of respective failure scenarios and to log into an exception table?
3.response file needs to have entire record and a concatination of all the error codes in the next line.
4.what would be a better approach among
creating an external table with all char(2000) fields and writing a select statement
such as select * from ext_table where (emp id is not null and length(emp_id)<=10 and....to select only proper data);
or creating the external table to be same as employee table and creating a bad file? if this is the preferred how can I generate the custom error codes?
Could you please help me in achieving this!
Warm Regards,
Shankar.

You can do a one-time creation of an external table. After that, you can either overwrite the existing text file or alter the location. In the example below I have split your original sample file into two files, in order to demonstrate altering the location. You can make the external table all varchar2 fields as large as they need to be to accommodate all possible data. If you then create a staging table and rejects table of the same structure, you can create a trigger on the staging table such that, when you insert from the external table to the staging table, it inserts into either the employee table or rejects table with the concatenated error list. If you want this in a file, then you can just spool a select from the rejects table or use some other method such as utl_file. The following is a partial example. Another alternative would be to use SQL*Loader to load directly into the staging table without an external table.

External table: How to load data from a fixed format UTF8 external file

Hi Experts,
I am trying to read data from a fixed format UTF8 external file in to a external table. The file has non-ascii characters, and the presence of the non-ascii characters causes the data to be positioned incorrectly in the external table.
The following is the content's of the file:

Check the result in database:
select * from D_CREW_EXT;
I found the first row is incorrect. For each non-ascii character,the fields to the right of the non-ascii character are off by 1 character,meaning that the data is moved 1 character to the right.
Then I tried to use the option STRING SIZES ARE IN CHARACTERS instead of STRING SIZES ARE IN BYTES, it doesn't work either.
The database version is 11.1.0.6.

Hi,
I changed the BYTE in the create table part to CHAR, it still doesn't work. The result is the same. I think the problem is in ACCESS PARAMETERS.
Any other suggestion?

External Tables & Non English Characters

Hi
I am new to external tables, i wanted to know what i need to do to upload the data which is of non-English characters,
Example
i need to upload the data where the single file will have data for more than one non-english characters.
1. English
2. Chinese
3. Korean
let me know if any other alternative exists for the same.
Regards
Yram

Hi,
a good reference for External Tables is the manual: http://download.oracle.com/docs/cd/B19306_01/server.102/b14215/part_et.htm
If they are in one file, you can upload them all at once. Important will be how the data is stored in the file (UTF-8, UTF-16). This information you should set in the external table by using the CHARACTERSET clause, see the manual.
Your database also needs to support these characters!

External tables-Fixed length file

Hi All,
I have a fixed length file that i load daily using an External table. Recently, one of the field, IP length was changed and customer wants to send both old records with 8 byte length and new records with 11 byte length in the same data file, until complete migration takes place.
Will it be possible for External tables to handle this requirement?. Or Is there any other possibility to treat it.
The old file contains 104 fields with IP field position form 490 to 498. Total
The new file contains 104 fields with the IP position from 490 to 501.
Thanks,
Sri.

If the two record types are mixed in the same file, then you will have problems loading them. I can see two possible solutions, in no particular order of preference (using your example data):
1. Redefine the external table something like:
Position (record_type (1:1)
version (2:5)
data (6:41))then parse the remaining fields based on the version number when you select from the external table.
2. Create two external tables over the same file, one for version 1.00 and one for version 1.01 using the LOAD WHEN clause to determine which set of data to load when you select. Something like:
CREATE TABLE version1 ...
ORGANIZATION EXTERNAL ...
ACCESS PARAMETERS
(RECORDS DELIMITED BY newline
LOAD WHEN (version = 1.00)
< definition for the old format >
and
CREATE TABLE version101 ...
ORGANIZATION EXTERNAL ...
ACCESS PARAMETERS
(RECORDS DELIMITED BY newline
LOAD WHEN (version = 1.01)
< definition for the new format >Then yor processing would use something like:
SELECT ip, last_name
FROM version1
UNION ALL
SELECT ip, last_name
FROM version101HTH

SQL Loader versus External Table

If anyone has worked on external tables please let me know your views.

user637544 wrote:
for sqlldr i follow the following approach
1. truncate table
2. call sqlldr and load records in staging table
3. check for bad records
how do i tuncate, call external table and check bad records for external table.As part of the SQL*Loader control file you can tell it to truncate the table as part of the process before it loads in the data.
The key differences between SQL*Loader and External Tables are:
1. SQL*Loader is an external utility run from the o/s command line, whereas External tables are usable from within SQL and PL/SQL.
2. SQL*Loader can only load data up into the database, whereas External tables can allow you to read files and write files (10g onwards)
3. SQL*Loader has limited control on skipping rows etc. whereas External tables can be queried using SQL and has all the flexibility that SQL can offer.
4. SQL*Loader requires connection information to the database, whereas External tables are already part of the database
5. SQL*Loader can only change the source filename through dynamic o/s level scripts, whereas External tables can have the filename changed using an ALTER TABLE ... LOCATION ... command.
If you want to truncate your staging table before loading it with data from the external table, then you will just have to do that as a seperate step, because the external table is not associated with other tables. Simply truncate the other table and then query the data from the external table into the staging table.
External tables offer a lot more flexibility than using SQL*Loader.

Is 2 external table allowed for same table in the same db.
