UPPER function in external table definition ... ?

Greetings
Is there a way to specify a SQL function, like UPPER, in an external table column definition?
I know I can do it with SQL*Loader in the control file but I haven't found a way to do it in OWB?
I realize there are ways outside of the external table using a view, etc. but I'd like to reference the external table directly without having to create yet another object.
Thanks very much!!

How to use lpad function in external table definition?

i need to modify one column of .csv file using lpad and want to insert it in external table.
lpad(AMT,3,'0')
Please send the code

Hi,
Please read SQL and PL/SQL FAQ
Additionally when you put some code or output please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
The information you posted are quite poor. You don't expect to have an answer with such few details.
Anyway external table are read only.

UPPER() in external table definition

Hi,
Is it possible to apply the UPPER() function to character columns within an external table definition using the ORACLE_LOADER driver?
I've tried myself and have looked through the documentation, and it seems like this is not possible ... just wanted to double-check before moving forward with a different solution.
Thanks.

I've never seen an example of doing it nor do I see anywhere in the syntax that lends itself to such manipulation.
Consider creating a view.

LTRIM in an External Table Definition.

Hi,
We're using Oracle 11.2.
Seeing as there's little documentation on the Web about non-general External Table definitions, I want to put this question out there.
How do I put an Ltrim function into an External table definition?

Thanks,
That's one way would be to use a view on an external table definition but I know there's way to so it in the definition of the external table.

Substr in external table definition

Hi Guys,
I have an external table where I am loading a txt file. The issue being, in the txt file I have a column with a variable length. This column houses the application/website link that is not of a fixed length. My external table field width is 100, but the txt file value is more than that. Now, I want to only insert this field for the 100 characters.
I tried using substr as shown in the example below, but it fails. Any idea what could be the alternative or if I am doing it right?
Here's my external table properties (access parameters) and I am trying to use 'substr' on field4
records delimited BY NEWLINE
badfile BAD_DIR:'email_events%a_%p.bad'
LOGFILE LOG_DIR:'email_events%a_%p.log'
fields terminated by '\t'
missing field values are null
event_type,
cm_timestamp,
issue_id,
cm_uid,
field1,
field2,
field3,
field4 "substr(:field4,1,100)",
field5,
field6,
field7,
field8,
field9,
field10,
field11,
field12,
field13,
field14
)

Just set your external table definition to query the full thing and then when you come to insert that data to a real table from the external table you can apply the substr in that query.

KUP-01005 error in external table definition

Hello,
I'm facing an issue that I found it has been rose in the past but that never had an answer.
I'm using an external table to load a file on the database.
This file format is CSV (actually using ";" as delimiter) and it has header and trailer records that has the same format of data records, but contain field names in it.
E.g.:
FIELD_NAME1;FIELD_NAME2;...
I want to discard this records (for the header is easy, I can use SKIP 1 parameter) and the way I was trying to do this was using the following condition:
LOAD WHEN ( FIELD_NAME1 != "FIELD_NAME1" )
The problem arises when a record has the first field empty (hence NULL): the record is discarded.
Therefore I tried modifing the condition in this way:
LOAD WHEN ( ( FIELD_NAME1 != "FIELD_NAME1" ) OR ( ( FIELD_NAME1 = NULL ) )
but in this case I get the following error:
KUP-01005 : syntax error : found "null": expecting on of "blanks, double-quoted-string, hexprefix, identifier, single-quoted-string"
I've doublechecked Oracle reference and the NULL keyword is admitted - morover it is stated that a NULL value can be tested only against NULL value, otherwise the comparison returns false.
Can anyone help me solving this issue? Is it a bug in SQLLOADER Driver used by External Tables or an error in Oracle Reference?
Regards

It's an other option that I've already tried, but it doesn't work - and it is correct because in External Table statement I've specified to trim fields (LRTRIM), so there's no fields containing blanks (they're simply empty).
However, my main concern is that I tried to use a statement that should be correct - according to Oracle reference.
Instead I get an error regarding the syntax of the statement...
I think that I can workaround this problem - but it is a workaround, not a real solution... :-|

It would appear that you external table definition and the external data file data do not match up. Post a few input records so someone can duplicate the problem and determine the fix.

Error while importing external table

Hello,
I am getting the following error message when trying to import an external table:
SQL Exception
SQL Exception
Repository Error:SQL Exception..
Class Name: CacheMediator.
Method Name: getDDEntryFromDB.
Repository Error Message: ORA-22992: cannot use LOB locators selected from remote tables
I am using the "import..."- function of "external tables" in warehouse target module. The external table is working correctly when accessing it via sqlplus.
We are using owb version 10.2.0.1.
Any help would be appreciated.
Best regards
Alexander

My friends, this a documented BUG into Metalink, but there is no solution.
I used a simple workaround:
1. I created the external table into the database;
2. I created the external table into the OWB repository;
3. I DIDN'T DEPLOY THE EXTERNAL TABLE TO THE DATABASE;
4. I used the external table into my mappings with no problems;
5. Finishing, I deployed my mappings to the database without any errors.
Hope to help!,
Gustavo.

External Table Help

I have created an external table but when i try to select data it seems to be empty, where could be the problem?
Thanks

The log file and bad file are part of the external table definition. I'm not where where Oracle Warehouse Builder (OWB) would put those files-- they may be in the same directory as the data file. You could check the external table definition to be sure, though.

External table error in windows environment

Can i create external table from directory which is on network drive not on local server where oracle is intsalled. I am receiving follwoing error when I try to query external table poinittng to directory object on network drive in windows. Thanks

I suspect not. Copy the file to a local disk location, point the directory or a directory to it, update the external table definition if necessary, repeat. If this run works then you have your answer.

"File" tab in external table editor replaced by "Access Parameters"?

Hi,
I have a few external tables where the "File" tab in the external table editor is replaced by an "Access Parameters" tab.
Does anybody know what may have caused this or how to repair it?
Thanks,
Ed

Hi Ed
I have had that happen many times but have not figured out the root cause. The fix I used was pretty basic. Delete the external table and redefine it.
This has happened to me mostly when I move an external table definition from our TEST repository to PROD. It seems to lose the file definition it was originally attached to.
Since my external tables look exactly like my flat file sources it takes only a few seconds to recreate the external table.
I didn't spend any more time trying to figure out the 'why'.
Good luck.

Headers appear in external table

I have defined several external tables over text files that have been built in the same way - in excel, then saved as a csv file.
Most of them work fine but there is one that always returns the column headers as data. I cant understand how this happens for this one file when they are all built in the the same way. I have checked the ddl for the external tables and they are equivalent.
I realise I could set it to skip 1 row but I am loathe to do that because if this is some sort of bug then it may be resolved later resulting in the first row of data being lost - a problem that may not become obvious until found by end users.
I have tried rebuilding from scratch and get the same result.
Has anyone else faced this situation?

I don't know what the exact trick is that OWB does,
but when you sample the file you use for the external
table and tell OWB to use the first row for the
header names, it won't use the first line as a data
line, even though there's nothing to be found in the
external table definition that indicates that.Hi,
that's no trick. If you sample the file and use the first row for column names the first row only disapears in the wizard. The resulting external table definition doesn't contain a skip row statement in this case automatically. The reason why you don't recognize this is because per default the loader writes no bad files. So the header row is normally ignored (because it doesn't match the structure) and you don't find it in the external table. If you will configure your external tables based on a file with an header and a skip parameter = 0 to produce a bad file (Bad File Name = file.bad) you will find the header row in this bad file then.
The only right way ist to configure the skip parameter - not to repress the resulting errors.
In this special file I guess the header matches the structure of the external table, so it isn't ignored but loaded into the external table.

How to remove carraige return from the field while loading external table

I am facing an issue of not getting rid of carraige returns present in the fileds of the source .csv file while loading the records into external table.
I had tried using LRTRIM, but it does not help.
The error I am getting is:
KUP-04021: field formatting error for field POPULATION_DESCRIPTION
KUP-04037: terminator not found
I am pasting one record out of the .csv file which is causing this error as below:
"Business Card Accounts
",123,7 BizCard - Gamers,Control,"Business Card Accounts
",75270,75271
You can see the carraige return in the 1st field as well as 5th field. Filed are separated by commas & eclosed by double quotes.
Could anybody help on this please?

Can you copy the file to an external table only version, and then dos2unix it?
Alternatively, you can use the ACCESS PARAMETERS area in your external table definition to set that your RECORDS DELIMITED BY carriage returns, instead of the default.
Check out the example here http://www.psoug.org/reference/externaltab.html
