登录 SAP Business Technology Platform,找到 space 下本人创立好的 HANA Cloud 实例,右键菜单抉择 Copy SQL Endpoint,将 HANA Cloud 实例的 endpoint 拷贝下来:
25eeba68-24ce-4b2d-aaa5-ee8d599ff4a0.hana.trial-eu10.hanacloud.ondemand.com:443
稍后咱们在 Node.js 代码里,会应用到。
新建一个 Node.js 利用,装置 hana client 开发库:
npm install --save @sap/hana-client
残缺的源代码:
var hana = require("@sap/hana-client");var connOptions = { serverNode: "25eeba68-24ce-4b2d-aaa5-ee8d599ff4a0.hana.trial-eu10.hanacloud.ondemand.com:443", encrypt: "true", sslValidateCertificate: "false", uid: "DBADMIN", pwd: "Sgd",};var dbConnection = hana.createConnection();dbConnection.connect(connOptions, function (err) { if (err) throw err; dbConnection.exec( `SELECT TOP 1000 "REGION", "DESCRIPTION"FROM "PLAIN"."REGIONS"`, function (err, result) { if (err) throw err; for( var i = 0; i < result.length; i++) console.log(result[i]); dbConnection.disconnect(); } );});
执行后果:
Node.js 代码里打印的数据库表 REGIONS,来自 PLAIN schema:
留神,应用 DBADMIN 这个用户,只能拜访到该用户领有 access right 的数据库表。
例如咱们更换应用 Node.js 拜访的数据库表名称为 DB1.COMMUNITY:
此时,Node.js 利用报错:
Error: insufficient privilege: Detailed info for this error can be found with guid '6F6F68ED5F58804CB8C7B25D7559D0E0'
