About The Project

I needed a simple executable to explore and export data from an Oracle DB on a locked down corporate laptop/network. This was my starting point for an automated data retrieval program which I can't share publicly. This repo is public in hopes that someone else will find it useful.

Here's why:

• Oracle CLI produces broken CSV files
• Oracle Developer didn't work for me either.
• This is lightweight and simple;

Of course, no one tool will serve all projects since your needs may be different. So you may also suggest changes by forking this repo and creating a pull request or opening an issue.

Testing

We can test Orasuck using Oracle Database Free Edition. For more information, see Oracle Database Free Release Quickstart.

Run the Oracle DB container.

docker run --name oracle -p 1521:1521 -e ORACLE_PWD=Test123 container-registry.oracle.com/database/free:latest

Connect to the Oracle DB container.

docker exec -it oracle bash

Connect to the Oracle DB.

sqlplus sys@localhost:1521/FREE as sysdba

Create a user and grant privileges.

alter session set "_ORACLE_SCRIPT"=true;
CREATE USER test IDENTIFIED BY Test123;
GRANT CONNECT, RESOURCE TO test;
ALTER USER test QUOTA UNLIMITED ON USERS;

Create a table and insert some data.

CREATE TABLE test.test_table (id NUMBER, name VARCHAR2(50));
INSERT INTO test.test_table VALUES (1, 'John Doe');
INSERT INTO test.test_table VALUES (2, 'Jane Doe');

Grant select privileges.

GRANT SELECT ON test.test_table TO test;

Test the connection.

go run main.go -server "oracle://test:Test123@localhost:1521/FREE" "select * from test_table"
