SQL & PL/SQL :: UNC In External Tables?
Aug 10, 2011
I made a directory and a external table, pointing to a file in the created directory. It appears that using unc path in my directory, won't work with my external table. Although the unc path points to the same server as where the database server is located.Is my assumption correct?
create or replace directory DIVA_POK as '\tvm011gm_diva_dir$ronnendbga_pok'
create table KOT_AOT(
AOT_IDENTIFICERENDE_SLEUTELvarchar2(14),
AOT_BEGINDATUMGELDIGHEIDdate,
AOT_EINDDATUMGELDIGHEIDdate,

I am using an external table with numbers and joining the external table to fetch data and Insert into another table.I am altering the table within procedure to pass csv file name as parameter as It'll change each time. It's working fine but in case if my grouping id is having two gids, then Header from csv file is also inserted as row in to coupon_personlization_members.
I gave skip 1 in external table but for second GID, header is inserted as row.I don't want header to be inserted as row but header will be there on csv file.
Here is my procedure :
CREATE OR REPLACE
PROCEDURE proc_coupon_load(
p_grouping_id NUMBER,
p_file_name VARCHAR2)
[code]..

I have created a softlink to a data file orig_file.dat using the command ln -s orig_file.dat orig_file_link.dat
Now is it possible to create an external table using this linked file orig_file_link.dat
I am using this linked file to minimise the space usage because every month we get different data files and external table creation is done as a batch job copying the data file to another file whenever a new data file arrives. External table is created with the new file. so i need to check whether it is possible with the linked file instead of copying the file.

i am trying to create a external table.Table is getting created but there is no data.While checking the log file, its saying
KUP-04021: field formatting error for field CUST_CODE
KUP-04026: field too long for datatype
KUP-04101: record 1 rejected in file /data/mmi_mig_data/PCOM_CUSTOMER_1.csv

KUP-04026: field too long for datatype

But according to me in CSV file everything looks to be okay.External Table:
CREATE TABLE ET_PCOM_CUSTOMER(CUST_CODE VARCHAR2(12), CUST_TITLE VARCHAR2(12),
CUST_NAME VARCHAR2(240), CUST_MIDDLE_NAME VARCHAR2(240),

I'm not sure if this should go on this topic.
Anyway, I've loaded 5 .csv files through an external table and after doing it I tried to delete them.
But this error comes "Cannot delete 'filename': It is being used by another person or program".
I closed Oracle Developer and tried again deleting them manually, and the result was the same.
Tried restarting and deleting one .csv and it worked, but when I open sql dev and tried deleting the other files couldn't do it.
The question is: files that were used on external tables can't be deleted if developer is working?
The thing is that I've created a Stored Procedure that delete the files and obviously can't work. So, I should delete every time I load a csv file after restarting the computer.

How can I enable NOLOGGING in an External Table ?
My Table FT_PRICE_COST_MASTER is taking a long time(more than 1 hour) to excute inside the procedure. The statement is:
SELECT SUBSTR(m.sr_no,1,16) SR_NO, m.SKU_CODE, m.location_code, m.start_date, m.end_date, m.COST, m.tax, m.octroi, m.freight, m.cash_disc, m.scheme_disc, m.mrp, m.csp, m.rsp1_qty, m.rsp1_value, m.rsp2_qty, m.rsp2_value, m.rsp3_qty, m.rsp3_value, m.net_cost, m.final_cost, m.current_margin, m.pc_effect, m.created_by, m.creation_date, m.modified_by, m.modification_date, m.change_ind, m.tax_code,
[code]......
When I am recreating the External table with NOLOGGING keyword at the bottom of the synatx, it's showing "operation not supported". Else are there any other points that I should look to increase the execution time of the above statement ?

i just posted another topic where i heard about external table and i had a few questions concerning them. I thought it was best to create a new topic than to continue on the other one...
I noticed that to create an external table the CTL is like this:
CREATE TABLE emp_load (FIELDS description)
ORGANIZATION EXTERNAL (TYPE ORACLE_LOADER DEFAULT DIRECTORY ext_tab_dir
ACCESS PARAMETERS (RECORDS FIXED 62 FIELDS (employee_number CHAR(2),
[Code]...
1) This creates an external table, but, is it possible to Create a normal table in a CTL file? For physical tables, the table has to exist right?
2) if you create a view linked to 2 external tables and if the CSV files are updated each day, the external tables will be updated automatically, and the view will be updated as well?
3) Can't there be any synchronisation problems?
4) What happens if a select request (or someone requests on the view) while the CSV file is being updated?
5) Is there anyway you can protect the accesses from those tables/views when the CSVs are being updated?
6) Is it possible to create an index on these sort of tables?
7) Is it possible to index a view?
8) Are external tables visible on a tool like sql developper?

the following situation, I have a directory named /dat/global/stock/ inside this i will get files named differently for example below.abcdef.112dfgrt.2......
Here i want to load this file one by one into the external tables and generate one more file based on some enrichment.
Step 1. Have to take first file and to load into the ext table.
Step 2. Enrichment
Step 3.File generation.
Now here i am facing a problem that in that particular directory i usually get 1000 files so i need to get file one by one and to put in one more directory. how can i get file one by one and generate file by using oracle loader

I have got a procedure that successfully creates an oracle external table and populates it with the contents of a file. This works fine until I have a situation where one of the fields is a VARCHAR2(2) and I try to insert say, a 5 character value. When this happens the record in question does not get populated in the external table (and rightly so), but I could do with working out if there is a discrepancy in the number of records in the file and the number of records that actually make it into the table so I could inform the user that there is a problem.
I have attached the code that creates the external table and populates it.

I'm experiencing some problems when trying to import an 50Mb XML file to an Oracle database. In this XML file I do have several data from customers:
- Name
- Address
- Contacts
I also have several tables within the DB that would receive this information:
- Customer
- CustomerAddress
- CustomerContacts
The problem is that, with my XML Transformation and correspondent insertion onto the databse I'm having an huge problem of time expended. I'm having more than 3 hours to insert over 180.000 records on those tables. what can I do to accelerate the process?

I need to do some analysis and research to find if any of these 8000 tables I have in a spreadheet that are going to be spit off into a separate database are used by any of our PeopleSoft processes.
I'm assigned to Student Records identified by NTSR.
So for table AAP_ETHNIC_PMPT, I could do something like
SELECT *
FROM PSSQLTEXTDEFN
where SQLID like 'NTSR%'
AND upper(sqltext) like '%PS_AAP_ETHNIC_PMPT%';
But how can I automate this and search 8000 rows in column A2 of a spreadsheet? What other tables other than PSSQLTEXTDEFN or PSPROJECTITEM can I use to search for values of NTSR?

Every day we have use different data file for an external table to read from.
filename like this "filenameddmmyyyy"
Every day, I have to change name of datafile in external table script which is not a good way.
I want the automated way for external table to read the latest datafile from specified directory.
Further, there is anyway that we could know that the latest data file is available for external table.

when i am writing dump from external table, it is accessing records from dump.but when i am trying to access other dumps(create thru expdp) it is giving error.the logic i am following is mentioned below-
CREATE OR REPLACE DIRECTORY "DIR_GMS" AS 'D:Gopal_works est_env_files'
GRANT READ ON DIRECTORY dir_gms TO gopal;
GRANT WRITE ON DIRECTORY dir_gms TO gopal;
-- creating dump file in directory
CREATE TABLE emp_ext
ORGANIZATION EXTERNAL
(
TYPE ORACLE_DATAPUMP
DEFAULT DIRECTORY dir_gms
LOCATION ('emp_ext_dmp.dmp')
)
[code]......
i am able to see records.
New point:
-- taking export thru expdb
expdp hr/hr tables=EMPLOYEES directory=DIR_GMS dumpfile=HR_EMP.dmp logfile=expdpEMP.log
then i created one EXTERNAL TABLE TO access it.
CREATE TABLE emp_xt (
EMPLOYEE_ID NUMBER(5),
FIRST_NAME VARCHAR2(50),
LAST_NAME VARCHAR2(50))
ORGANIZATION EXTERNAL (
TYPE ORACLE_DATAPUMP
DEFAULT DIRECTORY dir_gms
LOCATION ('HR_EMP.DMP')

I'm trying to create a external table column validation.
I have data like this
First column is Numeric, second is Non-Numeric
1,X
2,Y
3,Z
There are chances that I may have data as following
1,X
2A,Y
3,Z
My requirement is whenever I get non-numeric data in first column I want to pass 0 or NULL. So, I have created a external table with following script.
CREATE TABLE EXT_test
(
SL NUMBER (4),
BRANCH_NAME VARCHAR2 (100)
)
ORGANIZATION EXTERNAL
(
[code]........
Following is the code for function is numeric
function isnumeric( p_string in varchar2) return boolean as
l_number number;
begin
l_number := p_string;
return TRUE;
exception
when others then
return FALSE;
end;
It is not recognizing function IS NUMERIC. Is there any way, I can do this through External Table.
I'm getting error like
The following error has occurred:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error

I have an external table. The table gets created successfully. Once the table is created when I try to access it, I get the following error :
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
error opening file /cmpnt/dev/test/ADE_TEMP_4992.log
The default directory is valid and does not have any issues. The IP address of my DB server and the server from which I am connecting to the DB are different. Is this is the issue ? However , all SQL queries are working fine except this one.

I have to cleanup data from our tables (Production Environment) that contain millions of rows. The question is apart from the solution of the partitioned tables what alternative recommended solution suggests Oracle?
To delete these tables by using a cursor PL/SQL block or to import all the database and in the tables that we want to remove the old rows to use the QUERY option of the data pump utility.
I have used both ways and i have to admit that datapump solution is much much faster than the deletion that suffers from I/O disk.The question again is which method from these two is more reliable and less risky for the health of the database.

I came across an implementation where data from DB2 tables are moved to Oracle tables, for BI solutioning, using some oracle procedures called from MS SQL DTS packages which are scheduled jobs.Just being curious, can this be done using OWB or ODI rather than the above detour. I suppose there are some changes being done in those procedures before the data is being loaded into Oracle tables, can't this be done using OWB/ODI? Can it be scheduled too as jobs using OWB/ODI?

In a control file, the code is as follows:
load data
infile 'C:\Documents and Settings\xxxxx\Desktop\abc.txt'
APPEND
PRESERVE BLANKS
INTO TABLE table1
[code]...
When I run the above control file in sqlldr, I'm getting the error as
Record 1: Rejected - Error on table table1, column column3.
ORA-01481: invalid number format model
In the table the column3 data type is NUMBER(6,2).: The column size in table is 6 and position of column3 in control file is only 4. Also if possible let me know how the same data (send me 2 dummy records) which exactly works for the above control file especially for column3 where decimal number comes in the flat file.
For generating the flat file, for column3, i'm using LPAD(:value,4,0) in the select query column list.
