U-SQL文本提取器整数

Question

我需要从文件中提取数据，请参见下面的代码。

@rows =
EXTRACT booking_date string,
        route string,
        channel string,
        pos string,
        venta string,
        flight_date string,
        ancillary string,
        paxs int?
FROM "/ventas/ventas1.csv"
USING Extractors.Text(delimiter:';', silent:true);

@output =
    SELECT booking_date,
           channel,
           Convert.ToDouble(venta.Replace(",", ".")) AS venta,
           paxs
    FROM @rows;

我的问题是数字是西班牙语格式，意思是“ 100,234”而不是“ 100.234”。 有谁知道如何更改Extractors.Text中的格式，或者如何在U-SQL中将字符串转换为整数？

将列作为字符串导入并替换句号，例如：

@input =
    EXTRACT venta string,
            paxs int
    FROM @inputFile
    USING Extractors.Text(delimiter : ';');


@output =
    SELECT Convert.ToInt32(venta.Replace(".", "")) AS venta
    FROM @input;
