Question

Usimh SQL Loader in workflow process.

Asked by: Chirag1211

Hi Experts,

I have couple questions regarding requirement which I am working right now. Currently, we have a requirement of loading large number of records into Oracle tables. So we figured out of using SQL Loader for that purpose. So my questions for this requirement are here.

1. Can I Call SQL Loader in a Stored Procedure if Yes how?
2. How is the Error handling done in SQL Loader, like can i store the no of error records into a Oracle table, so that i can log the no of errors in a particular data load.

Can Anybody help on this. I would like to see some code examples on error handling.

Thanks In Advance

Chirag Patel

You can use External tables...

Let's say that you have a text file located in a specific directory, all you need to do is create an interface for that file using the external table construct.

e.g. --> C:/Vendors.txt

To create an interface for the above file, you frst need to create a directory for C:\, which I'm naming CDIR, then your external table as below:

CREATE TABLE VENDORS(
VENDOR_NAME VARCHAR2(100),
TAXPAYER_ID VARCHAR2(15),
VENDOR_NUMBER VARCHAR2(15),
IRS_ORIG_TYPE VARCHAR2(30),
VENDOR_ADDR1 VARCHAR2(50),
VENDOR_ADDR2 VARCHAR2(50),
VENDOR_ADDR3 VARCHAR2(50),
VENDOR_CITY VARCHAR2(20),
VENDOR_STATE VARCHAR2(5),
VENDOR_ZIP VARCHAR2(15),
VENDOR_AREA_CODE VARCHAR2(5),
VENDOR_PHONE VARCHAR2(10)
)
ORGANIZATION EXTERNAL
(TYPE ORACLE_LOADER
DEFAULT DIRECTORY CDIR
ACCESS PARAMETERS
(
RECORDS DELIMITED BY NEWLINE
NOBADFILE
NODISCARDFILE
NOLOGFILE
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
MISSING FIELD VALUES ARE NULL
REJECT ROWS WITH ALL NULL FIELDS
)
LOCATION ('VENDORS.TXT'))
REJECT LIMIT UNLIMITED;

Additionally, you can also specify where you want BADFILEs, DISCARDFILEs & LOGFILEs to go (the above table is not logging anything)

Once you have your external table, you can select from it as it's a normal table and call it from within a procedure as well where you can load your big table and handle exceptions...
