Example to store file in Oracle database:

by

To store a file in an Oracle database, you can use the BLOB (Binary Large Object) data type. The following is an example of how to store a file in an Oracle database using SQL*Plus:

  1. Create a table with a BLOB column to hold the file:
CREATE TABLE file_storage (
   id NUMBER PRIMARY KEY,
   file_name VARCHAR2(100),
   file_data BLOB
);

2. Insert a file into the table using the SQL*Loader utility:

sqlldr userid=username/password control=filename.ctl

The filename.ctl file should contain the following information:

load data
infile 'filename'
into table file_storage
fields terminated by ","
(id, file_name, file_data char(20000000))

Replace “filename” with the actual name of the file you want to insert.

3. Query the file from the database:

SELECT file_data FROM file_storage WHERE id = 1;
  1. Replace “1” with the actual ID of the file you want to retrieve.

Note: The above example uses SQLPlus and SQLLoader to insert the file into the database. You can also use other tools and programming languages to accomplish the same task.
