Oracle

Error message

Oracle

What it means

This is a Rust `todo!()` panic: the `get_relation` dispatcher has `todo!("Oracle")` because Oracle relation lookup is not implemented yet. Any relation resolution with an Oracle adapter panics with the message 'Oracle'. It indicates an incomplete adapter, not a database error.

Solutions

  1. Switch to an adapter type with implemented metadata lookup until Oracle support lands
  2. Implement oracle_get_relation querying ALL_TAB_COLUMNS/ALL_OBJECTS or the adapter's INFORMATION_SCHEMA bridge and wire it into the match
  3. Pin a dbt-adapter version where the Oracle arm is implemented
  4. Validate adapter capabilities at startup so unimplemented adapters are rejected with a clear message

Example fix

// before
AdapterType::Oracle => todo!("Oracle"),
// after
AdapterType::Oracle => oracle_get_relation(
    adapter, state, ctx, conn, database, schema, identifier, token,
),
Defensive patterns

Strategy: validation

Validate before calling

if adapter_type == AdapterType::Oracle {
    return Err("Oracle get_relation is unimplemented in this version".into());
}

Type guard

fn oracle_ready(t: &AdapterType) -> bool { !matches!(t, AdapterType::Oracle) }

Try / catch

let ok = std::panic::catch_unwind(|| get_relation(...));
if let Err(_) = ok { return Err(AdapterError::NotImplemented("Oracle get_relation")); }

Prevention

When it happens

Trigger: Calling `get_relation` (public) with AdapterType::Oracle; the arm at crates/dbt-adapter/src/metadata/get_relation.rs:87 executes `todo!("Oracle")`.

Common situations: Running dbt against an Oracle Database (on-prem or Autonomous DB) while the Oracle adapter is still stubbed in dbt-adapter; the panic occurs the first time dbt checks whether a relation exists.
