Windows下NodeJs操作Oracle环境搭建（转）

操作系统: Windows8 64

node-module: node-oracle(https://github.com/joeferner/node-oracle)

安装过程中如果出现找不到 v8.h 之类的错误,请升级node到最新版!

1.安装node

  node官网(http://nodejs.org/download/)下载 node-v0.10.28-x64.msi (http://nodejs.org/dist/v0.10.28/x64/node-v0.10.28-x64.msi)安装;

2.安装 Oracle instant client(http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html)

  Oracle instant client 是 Oracle 提供的访问数据库的 C++接口, 下载windows 64位(http://www.oracle.com/technetwork/topics/winx64soft-089540.html) Version 12.1.0.1.0 中的 instantclient-basic-windows.x64-12.1.0.1.0.zip和instantclient-sdk-windows.x64-12.1.0.1.0.zip; 并把它们解压到 C:\instantclient_12_1 文件夹中, 由于两个 zip 中的文件各不相同, 可以合并到同一个文件夹.

3.安装vs2012/2010

4.安装Python2.x

5.设置系统环境变量

  OCI_INCLUDE_DIR=C:\instantclient_12_1\sdk\include
  OCI_LIB_DIR=C:\instantclient_12_1\sdk\lib\msvc\vc11
  OCI_VERSION=12
  Path=...;c:\instantclient_12_1\vc11;c:\instantclient_12_1
  注意: 对于2中下载的两个 zip 文件, OCI_VERSION 应设置为 12, 如果设置成 11, 则安装时会报错:  LINK : fatal error LNK1181: cannot open input file 'C:\instantclient_12_1\sdk\lib\msvc\vc11\oraocci11.lib' ;
  请确保 Path 中 c:\instantclient_12_1\vc11 在 c:\instantclient_12_1 前面. 如果Path中存在其他版本的oracle client配置,请保证 "c:\instantclient_12_1\vc11;c:\instantclient_12_1" 在 oracle client前.

6.安装 node-oracle

  npm install oracle -g

  (使用-g安装为全局modules,如果在某个project下使用,可以在project目录中实行 npm link oracle)

  成功安装后会显示 node-oracle 的版本号及实际安装到的目录.

7.测试:

  建表:

CREATE TABLE NODE_TEST

(

  A INTEGER,

  B INTEGER

);

INSERT INTO NODE_TEST(A, B) VALUES (1, 2);

INSERT INTO NODE_TEST(A, B) VALUES (3, 4);

  查询:select.js

var oracle = require('oracle');

var connectData = {"hostname": "localhost", "database": "XE" ,

                   "user": "用户名", "password": "密码"};

oracle.connect(connectData, function(err, connection) {

  if ( err ) {

    console.log(err);

  } else {

    connection.execute("SELECT * FROM NODE_TEST", [], function(err, results) {

      if ( err ) {

        console.log(err);

      } else {

        console.log(results);

      }

      connection.close();

    });

  }

});

执行

新增:insert.js

var oracle = require('oracle');

var connectData = {"hostname": "localhost", "database": "XE" ,

                   "user": "用户名", "password": "密码"};

oracle.connect(connectData, function(err, connection) {

  if ( err ) {

    console.log(err);

  } else {

    connection.execute(" INSERT INTO NODE_TEST (A, B) " +

                       " VALUES (:1, :2) RETURNING A INTO :3 ",

                       ['5', '6',  new oracle.OutParam()],

                       function(err, results) {

        if ( err ) {

          console.log(err)

        } else {

          console.log(results);

        }

        connection.close();

      }

    );

  }

});

执行

删除:delete.js

var oracle = require('oracle');

var connectData = {"hostname": "localhost", "database": "XE" ,

                   "user": "用户名", "password": "密码"};

oracle.connect(connectData, function(err, connection) {

  if ( err ) {

    console.log(err);

  } else {

    connection.execute("DELETE FROM NODE_TEST WHERE A = :1",

                       [5],

                       function(err, results) {

      if ( err ) {

        console.log(err);

      } else {

        console.log(results);

      }

      connection.close();

    });

  }

});

  执行

更新:update.js

var oracle = require('oracle');

var connectData = {"hostname": "localhost", "database": "XE" ,

                   "user": "用户名", "password": "密码"};

oracle.connect(connectData, function(err, connection) {

  if ( err ) {

    console.log(err);

  } else {

    connection.execute("UPDATE NODE_TEST SET B = :1 WHERE A = :2",

                       [8, 3],

                       function(err, results) {

      if ( err ) {

        console.log(err);

      } else {

        console.log(results);

      }

      connection.close();

    });

  }

});

  执行

DDL:

var oracle = require('oracle');

var connectData = {"hostname": "localhost", "database": "XE" ,

                   "user": "用户名", "password": "密码"};

oracle.connect(connectData, function(err, connection) {

  if ( err ) {

    console.log(err);

  } else {

    connection.execute("ALTER TABLE NODE_TEST ADD (C INT)",

                       [],

                       function(err, results) {

      if ( err ) {

        console.log(err);

      } else {

        console.log(results);

      }

      connection.close();

    });

  }

});
