});

function GetDataFromSqlServerA() {
    return new Promise(function(resolve, reject)    {

        let sql = require("mssql")

        let sqlConnectionDetails = {
            user: 'test',
            password: 'foobar',
            server: 'SQLServerA', 
            database: 'DatabaseA'
        }

        sql.connect(sqlConnectionDetails, function (error)    {

            let sqlRequest …
