nodejs linux下配置oracle支持

upkdbaiaox

在oracle网站下载oracle数据库客户端连接包
instantclient-basic-linux，instantclient-sdk-linux
解压oracle客户端连接模块
$ unzip instantclient-basic-linux-11.2.0.3.0.zip
$ unzip instantclient-sdk-linux-11.2.0.3.0.zip
$ sudo mv instantclient_11_2/ /opt/instantclient
$ cd /opt/instantclient
$ sudo ln -s libocci.so.11.1 libocci.so
$ sudo ln -s libclntsh.so.11.1 libclntsh.so
配置环境变量
$ export OCI_INCLUDE_DIR=/opt/instantclient/sdk/include/
$ export OCI_LIB_DIR=/opt/instantclient
进入nodejs目录  安装oracle模块支持
$ cd /usr/local/lib
$ npm install oracle
export LD_LIBRARY_PATH=/opt/instantclient
编写oracle.js文件 测试连接于执行sql是否正常
var oracle = require("oracle");
oracle.connect({ "hostname": "localhost", "user": "demo", "password": "demo", "database": "orcl", "port": 1521}, function(err, connection) {
if(err) {
console.log(err);
}
// selecting rows 注意 connection.execute 方法必须要三个参数 不然会出错
connection.execute("SELECT * FROM TEST WHERE ID = :1", ['1'], function(err1, results) {
// results will be an array of objects
console.log("query start");
if(err1) {
console.log(err1);
}
// console.log(results.length);
for(var i = 0; i < results.length; i++) {
console.log(results.ID);
}
connection.close();
});
});
