使用nodejs应用查询SAP HANA Express Edition里的数据

const hanaClient = require("@sap/hana-client");
const connection = hanaClient.createConnection();
const connectionParams = {
    host : "hxehost",
    port : 39013,
    uid  : "SYSTEM",
    pwd  : "********",
    databaseName : "HXE"
}
connection.connect(connectionParams, (err) => {
    if (err) {
        return console.error("Connection error", err);
    }
    const whereClause = process.argv[2] ? `WHERE "group" = '${process.argv[2]}'` : "";
    const sql         = `SELECT "name" FROM food_collection ${whereClause}`;
    connection.exec(sql, (err, rows) => {
        connection.disconnect();
        if (err) {
            return console.error('SQL execute error:', err);
        }
        console.log("Results:", rows);
        console.log(`Query '${sql}' returned ${rows.length} items`);
    });
});
