|
|
Sequelize is a promise-based Node.js/io.js ORM for Postgres, MySQL, MariaDB, SQLite, Microsoft SQL Server and Oracle. It features solid transaction support, relations, read replication and more.
|
||
|
|
|
||
|
|
### Note
|
||
|
|
sequelize-oracle is a fork of [sequelize@master](https://github.com/sequelize/sequelize/tree/master)
|
||
|
|
This fork add support of DML statements for Oracle
|
||
|
|
If you don't need Oracle support, prefer the original [Sequelize](http://sequelizejs.com/)
|
||
|
|
|
||
|
|
Sequelize-oracle@3.0.1-x.x is in development. Only the old version (1.7.10-x.x) is on npmjs registry.
|
||
|
|
|
||
|
|
## Compatibility:
|
||
|
|
Sequelize-oracle is compatible only with nodejs@0.10 and nodejs@0.12 (with oracledb >= 0.6).
|
||
|
|
Sequelize-oracle is only tested with Oracle 11 XE and nodejs@0.10
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
The basic install steps are:
|
||
|
|
|
||
|
|
- Install oracledb
|
||
|
|
- Install the small, free [Oracle Instant Client](http://www.oracle.com/technetwork/database/features/instant-client/index-100365.html) libraries if your database is remote, or have a local database such as the free [Oracle XE](http://www.oracle.com/technetwork/database/database-technologies/express-edition/overview/index.html) release.
|
||
|
|
- Run `npm install oracledb` to install from the NPM registry.
|
||
|
|
|
||
|
|
See [INSTALL](https://github.com/oracle/node-oracledb/blob/master/INSTALL.md) for details.
|
||
|
|
|
||
|
|
- Install sequelize-oracle
|
||
|
|
- Run `npm install sequelize-oracle` to install from the NPM registry.
|
||
|
|
|
||
|
|
## Oracledb config in Sequelize-Oracle
|
||
|
|
- With Oracledb, the maximum number of rows that are fetched by select query is 100 rows. You can change this parameter with options.maxRows in each query.
|
||
|
|
- In Sequelize, for Raw query, the outFormat parameter for oracledb is OBJECT.
|
||
|
|
- AutoCommit is enable by default. If you don't want autoCommit, use Sequelize Transactions for manage commit et rollback.
|
||
|
|
|
||
|
|
|
||
|
|
## Limitations:
|
||
|
|
|
||
|
|
- DataType: only this dataTypes are managed:
|
||
|
|
- STRING (=VARCHAR2)
|
||
|
|
- CHAR
|
||
|
|
- DECIMAL (=NUMBER)
|
||
|
|
- BIGINT (=NUMBER(19,0))
|
||
|
|
- INTEGER
|
||
|
|
- FLOAT
|
||
|
|
- DOUBLE
|
||
|
|
- UUID (=CHAR 36)
|
||
|
|
- DATE (=TIMESTAMP WITH LOCAL TIME ZONE)
|
||
|
|
- DATEONLY (=DATETIME)
|
||
|
|
- BOOLEAN (=NUMBER(1))
|
||
|
|
- Index: index type is not fully managed
|
||
|
|
|
||
|
|
## Todo:
|
||
|
|
- ENUM DataType
|
||
|
|
- improve index for type
|
||
|
|
- resolve the pb "name column length > 30 char" in nesteed querry
|
||
|
|
- ...

From 3.0.0 and up Sequelize will follow SEMVER. 3.0.0 contains important security fixes so we highly recommend that users upgrade.
