erlangbureau/jamdb_oracle

This system is a database connectivity library for Erlang and Elixir that enables interaction with Oracle databases. It provides a native Erlang driver for low-level SQL execution and connection management, alongside a fully functional Ecto adapter for high-level ORM operations such as migrations, CRUD queries, and transaction handling. The project supports standard database features including SSL connections, TNS protocol encoding, and cryptographic authentication.

The library now includes an Ecto adapter, allowing users to connect to Oracle databases using the Ecto ORM in addition to the existing Erlang driver. The project build system has been updated to support rebar3, and the minimum required Erlang/OTP version is now 22.0.

This change introduces the initial version of the JAMDB Oracle database driver. It adds the core Erlang header files (\TNS.hrl\, \jamdb\_oracle.hrl\, \jamdb\_oracle\_defaults.hrl\) that define the TNS protocol constants, data types, connection environment records, and default configuration values (such as port 1521 and fetch size 15) required to interact with Oracle databases.

include · high confidence

This update introduces the \Jamdb.Oracle\ library as a fully functional Ecto adapter for Oracle databases. The \lib\ directory now contains the core connection driver (\Jamdb.Oracle\ implementing \DBConnection\), the Ecto adapter module (\Ecto.Adapters.Jamdb.Oracle\), and modules for query generation (\Jamdb.Oracle.Query\) and SQL DDL execution (\Jamdb.Oracle.SQL\). Users can now use Ecto to interact with Oracle, supporting standard operations such as migrations, CRUD queries, and transaction management.

lib · high confidence

This change introduces the initial version (0.5.12) of the jamdb\_oracle library, providing an Erlang driver for connecting to Oracle databases. The package includes the core application definition, a gen\_server-based API module (jamdb\_oracle) for executing SQL queries, a connection manager (jamdb\_oracle\_conn) handling TCP/SSL sockets and session lifecycle, and modules for TNS protocol encoding/decoding and cryptographic authentication (including 12c/18c password versions and PBKDF2).

src · high confidence

Added a full test suite for the Jamdb Oracle Ecto adapter, including Elixir-based ExUnit tests (\jamdb\_oracle\_test.exs\) that verify SQL generation for queries, joins, CTEs, and schema prefixes, alongside Erlang Common Test suites (\jamdb\_oracle\_SUITE.erl\, \jamdb\_oracle\_test.erl\) covering basic operations, data types, and procedures. The change also introduces test helper modules for database administration (\jamdb\_oracle\_dba.erl\) and binary pretty-printing (\jamdb\_oracle\_binpp.erl\), example configuration files for SSL and non-SSL connections, and patches to address Erlang/OTP SSL compatibility issues in older versions.

test · high confidence

The project's dependency manifest (mix.exs) has been updated to declare a dependency on the ecto\_sql library, specifically version 3.12 or higher. This change ensures the application correctly links against the Ecto SQL adapter required for database interactions.
