I don't know of any way to make it automatically skip footers. Hopefully, the footer doesn't match your data structure, so that it couldn't get loaded as a record, then it would just go to your bad file.

External table - bad row - Please help

Hi,
I have one external table which is associated with a LOAN.DAT file.
If some rows are bad means external table is dumping a bad file with
the 'bad row' in .bad file. Is there any way to identify what is the reason for
this or which column caused the row to be bad?
Regards,
Mathew Collins.

Hi Mathew,
Is there any way to identify what is the reason for this or which column caused the row to be bad?
Not that know of. I usually just carefully inspect the row and compare it with the format mask:
I have a reproduceable example, here, this might help:

Skipping header in external table...

Is it possible to define an external table within OWB to skip the first few rows of a file? I haven't been able to find anything in the configuration of an external table that allows you to skip lines.
If it is not available, will it be be added to OWB in the future?
I am running OWB 9.2.0.2.8
Thanks

I think I have found a bug in OWB. I keep losing the number of rows to skip in external tables.
I defined a File to skip the first three rows then created an external table based on the File. When I deployed the external table, "SKIP 3" was generated. Later, I made some configuration changes to the external table (setup a BAD file/location, set it to trim the fields, load Nulls, etc). When I redeployed the external table, "SKIP 3" was missing.
Then I did an MDL export of the File. In the MDL file, "SkipRecords" was 0. I changed it to 3, and then imported the MDL back into OWB (match by UOID, replace existing). Then when I redeployed the external table, "SKIP 3" was back in the definition.
Is this a known issue? Is it fixed in the latest version? I am using OWB 9.2.0.2.8.
Thanks!

File loaded successfully by SQLldr but external table failed

Hi ,
When i tried to create an external table to load data from file it failed with the below error
"KUP-04018: partial record at end of file",
When i query on the external table for rows with rownum<2500 i can see the records being properly loaded but when i tried to fetch all records it throws the above error.
But the same file when i loaded with sqlldr it loaded all the records successfully.
Can you please let me know the reason for this?
Regards

Can you post us your SQLLDR control file, your external table definition, a sample of your data (preferably including the last lines of data which you believe are erroring) and also let us know your database version.

Selecting only required number of rows in an external table

Hi,
I have an external table with many flat files as source.. I know I can skip rows using the keyword 'SKIP'. I want to select only first 'n' rows from all the flat files as the rows available in my oracle external table. Is this Possible?...
eg..
Flat file 1
c1,c2
123,45
132,56
'ahgh',34
'dfd',22
Flat file 2
c1,c2
56,1212
545,45
'ahcsd',4
'dds',24
I want to create a file which contains the rows, means only the 2nd and 3rd rows from each flat files
123,45
132,56
56,1212
545,45
Thanks in Advance
Poulose

If this means selecting from all these flat files at the same time then it might get a bit cumbersome. Basically you will have to create an external table for each flat file and then do something like this:
SELECT * FROM
( select c1, c2 from
     ( select c1, c2, rownum as rn from ext_table_1 )
    where rn in (2, 3)
   union all
    select c1, c2 from
     ( select c1, c2, rownum as rn from ext_table_2 )
    where rn in (2, 3)
   union all
select c1, c2 from
     ( select c1, c2, rownum as rn from ext_table_3 )
    where rn in (2, 3)
   union all

How to implement row level security using external tables

Hi All Gurus/ Masters,
I want to implement row level security using external tables, as I'm not sure how to implement that. and I'm aware of using it by RPD level authentication.
I can use a filter condition in my user level so that he can access his data only.
But when i have 4 tables in external tables
users
groups
usergroups
webgrups
Then in which table I need to give the filter conditions..
Pl let me know this ...

You pull the Group into a repository variable using a session variable init block, then reference that variable in the data filters either in the LTS directly or in the security management as Filters. You reference it with the syntax VALUEOF("NQ_SESSION.Variable Name")
Hope this helps

How to reject external table rows with some blank columns

How to reject external table rows with some blank columns
I have an external table and I would like to reject rows when a number of fields are empty. Here are the details.
CREATE TABLE EXTTAB (
ID NUMBER(10),
TSTAMP DATE,
C1 NUMBER(5,0),
C2 DATE,
C3 FLOAT(126)
ORGANIZATION EXTERNAL (
TYPE ORACLE_LOADER
DEFAULT DIRECTORY EXT_DAT_DIR
ACCESS PARAMETERS (
RECORDS DELIMITED BY NEWLINE
LOAD WHEN (NOT (c1 = BLANKS AND c2 = BLANKS AND c3 = BLANKS))
LOGFILE EXT_LOG_DIR:'exttab.log'
BADFILE EXT_BAD_DIR:'exttab.bad'
DISCARDFILE EXT_BAD_DIR:'exttab.dsc'
FIELDS TERMINATED BY "|"
LRTRIM
MISSING FIELD VALUES ARE NULL
REJECT ROWS WITH ALL NULL
FIELDS (
ID,
TSTAMP DATE 'YYYYMMDDHH24MISS',
C1,
C2 DATE 'YYYYMMDDHH24MISS',
C3
) LOCATION ('dummy.dat')
REJECT LIMIT UNLIMITED
So, as you can see from the LOAD WHEN clause, I'd like to reject rows when C1, C2 and C3 are empty.
The above statement works fine and creates the table. However when I am trying to load data using it, the following error is produced:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
KUP-00554: error encountered while parsing access parameters
KUP-01005: syntax error: found "not": expecting one of: "double-quoted-string, identifier, (, number, single-quoted-string"
KUP-01007: at line 1 column 41
ORA-06512: at "SYS.ORACLE_LOADER", line 14
ORA-06512: at line 1
It seems that external tables driver does not understand the "NOT (...)" condition. Could anyone suggest how I can achieve what I want in a different way?
Thank you.
Denis

Another method would be to simply remove the "LOAD WHEN condition" and create a view on the external table which filters the data.
CREATE EXTTAB_VIEW AS
SELECT * FROM EXTTAB
WHERE not (c1 is null and c2 is null and c3 is null);

External table and discarded rows

I need to load a table mapping an external table.
Sometimes some rows are discarded due to constraints violation or bad values in the file.
How is it possible to identify the discarded rows?
Is it possible to automatically create a file containing the
discarded records?
Thanks, Gio.

Before specify a location, you have to create/define directories in the database and set permissions on them.
Add the location(s) to OWB and register them.
Right click on the external table, choose CONFGURE.
Navigate to ACCESS SPECIFICATION. set the locations here.

How to find rejected rows using External Table

Hi all,
I had written a stored procedure to read comma(,) separated flat file using External Tables in oracle 9i with Reject Limit "Unlimited" Option. Sometimes all rows are successfully loaded into external table and sometimes some rows are failed, I can find out those rows from logfile created by oracle. I want to inserted those rows key values into some other table. Can any body suggest/links how to write this.
Thanking you in advance

"Is there a way to have the system truncate the log files besides some O/S utility that will scour the directory every night, week, etc.?"
You can use UTL_FILE.FREMOVE to delete the file, if you have sufficient privileges. You can schedule it using DBMS_JOB if you like or run it before you recreate the file, as demonstrated below. The pl/sql block to check whether the file exists is used for demonstration purposes only and is not necessary. This is just one method. There are various ways to delete or truncate a file. This just seems like the simplest.

Is there a way to know how many rows were rejected using external tables?

Hi,
I'm developing a package that needs to load different kinds of text files into the DB.
I was wondering whether there's a way of knowing in SQL or PL/SQL how many rows were rejected if my external table is defined with "reject limit unlimited".
I'm using the external tables in "insert into ... (select ... from external_table where...)"
sql%rowcount returns the number of inserted rows
I was hoping for something similar/easy to get the number of rejected rows as well.
I know I can try to analyze the bad file for the number of records if there's no other way...
Thanks in advance.

Pyrocks wrote:
I was afraid of this answer...
this is a certain "no there's no other way" or should i wait for other responses (no disrespect - just want to make sure :) )Well the difference would be that this external table will have no complex logic. You would simple read in all the lines from the bad file. The chances that this is broken are therefore very slim compared with your original external table.
And tehre are many other ways possible. For example you can first copy the file into a real internal (temp) table without using any processing logic but with using an external table. Then do the processing / logic checking of the data and move the data from this temp table into your final data structure. Since you move the data two times the whole process will be slower then the original version.

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

Hi all, I need to load inside an external table records that contain 7 fields. The last field is called AMOUNT and it's represented in some records with the decimal format, in others records with the scientific notation format as, 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's script is the following:
CREATE TABLE HYP_DATA
COUNTRY VARCHAR2(50 BYTE),
YEAR VARCHAR2(20 BYTE),
PERIOD VARCHAR2(20 BYTE),
ACCOUNT VARCHAR2(50 BYTE),
DEPT VARCHAR2(20 BYTE),
ACTIVITY_LOC VARCHAR2(20 BYTE),
AMOUNT VARCHAR2(50 BYTE)
ORGANIZATION EXTERNAL

"ACCOUNT" Char,
"DEPT" Char,
"ACTIVITY_LOC" Char,
"AMOUNT" Char
LOCATION (HYP_DATA_DIR:'Total.txt')
REJECT LIMIT UNLIMITED
NOPARALLEL
NOMONITORING;
If, for the field AMOUNT I use the datatype VARCHAR (as above), the table is loaded but I have some records rejected, and all these records contain the last field AMOUNT with the scientific notation as:
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 the others records with a decimal AMOUNT are loaded correctly.
So, my problem is that I NEED to load all the records (with the decimal and the scientific notation format) together (without records rejected), but I don't know which datatype I have to use for the AMOUNT field....
Anybody has any idea ???
Any help would be appreciated
Thanks in advance
Alex

Just cut'n'paste of you script and example woked FINE for me.
however my quation is... An external table will LOAD all data or none at all. How are you validating/concluding that...
