Question

嗨，我正在尝试使用U-SQL进行连接，并且三个输入文件是文本文件，现在出现错误。我是新手。当我尝试加入时，它抛出以下错误。我已经尝试过：使用Extractors.Csv(encoding:System.Text.Encoding.GetEncoding("Windows-1252"));，但存在相同的错误。您能否帮助解决该错误：

{
    "errorCode": "2703",
    "message": "Error Id: E_CSC_USER_SYNTAXERROR, Error Message: syntax error. Expected one of: identifier quoted-identifier variable . Error Id: E_CSC_USER_RESERVEDKEYWORDASIDENTIFIER, Error Message: Reserved keyword FROM is used as an identifier.. Error Id: E_CSC_USER_SYNTAXERROR, Error Message: syntax error.

",
    "failureType": "UserError",
    "target": "U-SQL1"
}

U-SQL脚本

@customerData = EXTRACT 
    Customerid string,
    Name string,
    City string,
    State string,
    Country string,
    Account_Created string
FROM "/a_test/customer_data/[dbo].[customerData].txt"
USING Extractors.Csv(skipFirstNRows:1);


@productData = EXTRACT 
    Product string,
    Price string,
FROM "/a_test/product_data/[dbo].[productData].txt"
USING Extractors.Csv(skipFirstNRows:1);


@transactionData = EXTRACT 
    Transaction_date string,
    Product string,
    Payment_Type string,
    Customerid string,
    Name string,
    City string,
    Account_Created string,
    Last_Login string,
    Latitude string,
    Longitude string
FROM "/a_test/transaction_data/[dbo].[transactionData].txt"
USING Extractors.Csv(skipFirstNRows:1);

@result = 
SELECT 
    t.Customerid,
    t.Transaction_date,
    t.Product,
    t.Payment_Type,
    t.Name,
    t.City,
    c.State,
    c.Country,
    p.Price,
    t.Latitude,
    t.Longitude
  FROM @transactionData AS t
  INNER JOIN @productData AS p on t.Product = p.Product
  INNER JOIN @customerData AS c on t.Customerid = c.Customerid
  order by t.Customerid;

OUTPUT @result TO "/a_test/final_output"
USING Outputters.Csv();

Answer 1

@productData = EXTRACT 
Product string,
Price string,
FROM "/a_test/product_data/[dbo].[productData].txt"
USING Extractors.Csv(skipFirstNRows:1);

“价格”字符串列后有一个逗号（，），应删除该逗号。
