无法使用Google App脚本将SQL Server连接到Google Sheet

Question

我正在尝试使用App Script从本地数据库（SQL Server）连接到Google Sheet。但它表示连接错误。这是我的代码。

function SQLdb() {
    // Replace the variables in this block with real values.

    // Read up to 1000 rows of data from the table and log them.
    function readFromTable() {
        var user = 'sa';
        var userPwd = 'DBpass';
        var database = 'MyDBName'
        var connectionString = 'jdbc:sqlserver://127.0.0.1:1433;databaseName='+database;
        var conn = Jdbc.getConnection(connectionString, user, userPwd);

        var start = new Date();
        var stmt = conn.createStatement();
        stmt.setMaxRows(1000);
        var results = stmt.executeQuery('SELECT TOP 1000 * FROM dbo.myTable');
        var numCols = results.getMetaData().getColumnCount();

        while (results.next()) {
            var rowString = '';
            for (var col = 0; col < numCols; col++) {
                rowString += results.getString(col + 1) + '\t';
            }
            Logger.log(rowString)
        }

        results.close();
        stmt.close();

        var end = new Date();
        Logger.log('Time elapsed: %sms', end - start);
    }
    readFromTable();
}
