Oracle DBT

Tested with dbt==0.19.1

for dbt 0.18.0 and below, use dbt-oracle version 0.3.2

Installation

You need the oracle database client installed in your system in order for this to work, here (https://cx-oracle.readthedocs.io/en/latest/user_guide/installation.html) you can find the cx_oracle python driver installation instructions.

This (https://gist.github.com/tcnksm/7316877) gist is also a useful resource for installing the client in Ubuntu. It's an old link for Ubuntu 12 but it still works at least for ubuntu 18.

Installing:

pip install dbt-oracle==0.4.0

Configure your profile

dbt_oracle_test:
   target: dev
   outputs:
      dev:
         type: oracle
         host: localhost
         user: system
         pass: oracle
         port: 1521
         dbname: xe
         schema: system

Testing

There is a dummy dbt project called dbt_test_project for testing some things that the official dbt integration tests do not cover. For both dbt_test_project and dbt oficial adpter tests we are using a database user 'dbt_test' with password 'dbt_test' You have to either create this user os change the credentias at tests/oracle.dbtspec and dbt_test_project/profiles.yml

For running it first start an oracle database instance:

docker run \
--name dbt-oracle-db \
-d \
-p 1521:1521 \
epiclabs/docker-oracle-xe-11g

Install the project locally

python setup.py install

then run dbt seed and run (theres is a profile file compatible with oracle 11g docker defaults at the test dir)

cd dbt_test_project
dbt seed --profiles-dir ./
dbt run --profiles-dir ./
dbt test --profiles-dir ./

you can also run

make test

for running both dbt adapter tests and the dbt_test_project included in this repo

The following dbt adapter tests are passing:

tests/oracle.dbtspec::test_dbt_empty
tests/oracle.dbtspec::test_dbt_base
tests/oracle.dbtspec::test_dbt_ephemeral
tests/oracle.dbtspec::test_dbt_incremental
tests/oracle.dbtspec::test_dbt_snapshot_strategy_timestamp
tests/oracle.dbtspec::test_dbt_snapshot_strategy_check_cols
tests/oracle.dbtspec::test_dbt_schema_test

Known failing tests:

FAILED tests/oracle.dbtspec::test_dbt_data_test
FAILED tests/oracle.dbtspec::test_dbt_ephemeral_data_tests

The dbt adapter tests for data tests fails due to how the test_dbt_data_test sequence is implemented. You can use data tests with this adapter, there is an example at the test project in this repo.

Final Notes

This is a new project and any contribuitions are welcome.
