Question

CSV Format ScreenShot在表1中，有三列：COMPANY，AMOUNT和Vendor。查询后，我们将得到一个包含6列的表格：VENDOR，A，B，C，D，总计。

SELECT 'VENDOR','A','B','C','D','Total'
UNION ALL
SELECT 
    VENDOR,
    SUM(CASE
        WHEN COMPANY = 'A' THEN AMOUNT
        ELSE ''
    END) AS A,
    SUM(CASE
        WHEN COMPANY = 'B' THEN AMOUNT
        ELSE ''
    END) AS B,
    SUM(CASE
        WHEN COMPANY = 'C' THEN AMOUNT
        ELSE ''
    END) AS C,
    SUM(CASE
        WHEN COMPANY = 'D' THEN AMOUNT
        ELSE ''
    END) AS D,
    SUM(AMOUNT) AS Grand_Total
INTO OUTFILE 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/result.csv'
FROM
    table1
GROUP BY VENDOR_NAME;

问题是：当我尝试将查询结果导出到新的csv文件结果中时，我发现csv文件中的内容确实很乱... 在我的result.csv中：第一行是VENDORABCDTotal，第二行是Mike12340001234。所有字段和数据都在csv文件的第一列中。

您需要用逗号终止每个字段，并用换行符终止每一行：请使用以下命令导出数据：

SELECT 'VENDOR','A','B','C','D','Total'
UNION ALL
SELECT 
    VENDOR,
    SUM(CASE
        WHEN COMPANY = 'A' THEN AMOUNT
        ELSE ''
    END) AS A,
    SUM(CASE
        WHEN COMPANY = 'B' THEN AMOUNT
        ELSE ''
    END) AS B,
    SUM(CASE
        WHEN COMPANY = 'C' THEN AMOUNT
        ELSE ''
    END) AS C,
    SUM(CASE
        WHEN COMPANY = 'D' THEN AMOUNT
        ELSE ''
    END) AS D,
    SUM(AMOUNT) AS Grand_Total
INTO OUTFILE 'C:/ProgramData/MySQL/MySQL Server 8.0/Uploads/result.csv'
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\r\n'
FROM
    table1
GROUP BY VENDOR_NAME;
