What you can do

Browse tables and views of your schemas, the SQL editor with Explain (DBMS_XPLAN), exports. Read-only scripts run under SET TRANSACTION READ ONLY, with inline PL/SQL refused.

A least-privilege user

Wharfbase works with any user; give it only what you want it to do.

Read only

CREATE USER wharfbase_ro IDENTIFIED BY "…";
GRANT CREATE SESSION TO wharfbase_ro;
GRANT READ ON app.customers TO wharfbase_ro;  -- per table, or:
GRANT READ ANY TABLE TO wharfbase_ro;

Read and write

Grant SELECT, INSERT, UPDATE, DELETE on the tables instead of READ.

Functions with PRAGMA AUTONOMOUS_TRANSACTION can write even from a read-only transaction: a user with READ grants only is the hard guarantee.
