Install

• Install the Oracle Instant Client:

• Download the Instant Client Package: both "Basic Lite" and "SDK".

• Extract both the Basic Lite and the SDK zip files to /opt/instantclient/ (Linux/OS X) or C:\oracle\instantclient\ (Windows)

• or put them wherever you want and set the environment variables OCI_INCLUDE_DIR (to the sdk/include) and OCI_LIB_DIR (to the directory containing libocci.so.11.1 on Linux/OS X, or oraocci11.lib on Windows).

• Linux: add the shared object files to the ld cache:

  # Replace /opt/instantclient/ with wherever you extracted the Basic Lite files to
  echo '/opt/instantclient/' | sudo tee -a /etc/ld.so.conf.d/moo.conf
  sudo ldconfig

  • Create the symbolic links:

  	cd /opt/instantclient/
  	sudo ln -s libclntsh.so.11.1 libclntsh.so 
  	sudo ln -s libocci.so.11.1 libocci.so 

• Finally install using Node Package Manager (npm):

  npm install oracle

Example

var oracle = require("oracle");

oracle.connect({ "hostname": "localhost", "user": "test", "password": "test" }, function(err, connection) {
  // selecting rows
  connection.execute("SELECT * FROM person WHERE name = :1", ['bob smith'], function(err, results) {
    // results will be an array of objects
  });

  // inserting with return value
  connection.execute(
    "INSERT INTO person (name) VALUES (:1) RETURNING id INTO :2",
    ['joe ferner', new oracle.OutParam()],
    function(err, results) {
      // results.updateCount = 1
      // results.returnParam = the id of the person just inserted
    });

  connection.setAutoCommit(true);

  connection.commit(function(err) {
    // transaction committed
  });

  connection.rollback(function(err) {
    // transaction rolledback
  });

  connection.close(); // call this when you are done with the connection
});

Out Params

The following Out Params are supported in Stored Procedures:

OCCIINT
OCCISTRING
OCCIDOUBLE
OCCIFLOAT
OCCICURSOR
OCCICLOB
OCCIDATE
OCCITIMESTAMP
OCCINUMBER
OCCIBLOB

And can be used as follows:

connection.execute("call myProc(:1,:2)", ["nodejs", new oracle.OutParam(oracle.OCCISTRING)], function(err, results){
  console.dir(results);
};

When using Strings as Out Params, the size can be optionally specified as follows:

connection.execute("call myProc(:1,:2)", ["nodejs", new oracle.OutParam(oracle.OCCISTRING, {size: 1000})], function(err, results){

If no size is specified, a default size of 200 chars is used.

See tests for more examples.

In/Out Params

The following INOUT param types are supported:

OCCIINT
OCCISTRING
OCCIDOUBLE
OCCIFLOAT
OCCINUMBER

INOUT params are used like normal OUT prams, with the optional 'in' paramater value being passed in the options object:

connection.execute("call myProc(:1)", [new oracle.OutParam(oracle.OCCIINT, {in: 42})], function(err, results){
  console.dir(results);
};
