我正在尝试使用 php 脚本将一些 csv 和制表符分隔的 txt 提要导入我的数据库。除了这个之外，它们似乎都可以工作。

我有一个包含数据库连接、禁用键、导入每个提要（通过包含语句）和重新启用键的基本 php 脚本，然后再导出最终结果。

导致我出现问题的提要是这个，或者我应该说 sql 语句。

$sql = "

LOAD DATA LOCAL INFILE '../feeds/feed6.txt'
INTO TABLE supplierimport
FIELDS TERMINATED BY ','
ENCLOSED BY '\"'
LINES TERMINATED BY '\\r\n'
IGNORE 1 LINES
(@col1,@col2,@col3,@col4,@col5,@col6,@col7,@col8,@col9,@col10,@col11,@col12,@col13,@col14,@col15,@col16)
SET
DistributorID = 546, MPN=@col1, Brand=@col6, DistributorSKU=@col1, `Condition`=@col15, ProductName=@col2, Cost= replace(@col4, ',', ''), Stock=@col5, EAN=@col12, ImageURL=@col11, ETA=@col7";

database_queryModify($sql,$result);

print "Imported...";

所以，关于这个有两个问题：

  1. 使用这个说法是否正确；Cost= replace(@col4, ',', ''),我使用这个语句的原因是因为我将每个供应商的成本导入到cost我的数据库中的列中，但是这个特定的供应商使用千位分隔符，即1000.53在提要中显示为1,000.53，因此没有正确导入我的数据库，所以我找到了替换功能，但想验证我在这种情况下是否正确使用它？

  2. 文件中正好有一半的行被导入到我的数据库中。我发现了这个问题；如您所见，mysql 使用设置字段加载数据本地 infile 语法问题我已经放了 \r\n，但它仍然没有全部导入。

任何人都可以帮忙。

谢谢

编辑：仅以逗号分隔的文本文件中的三行为例。这是从文件中粘贴的，因此我没有在每行之间添加额外的行。此外，在第 3 行，您会看到价格为“1,117.00”，以显示千位分隔符的工作方式：

"Item No.","Description","Description 2","Customers Price","Home stock","Brand Name","Expected date for delivery","Item Group No.","Item Group Name","Item Product Link (Web)","Item Picture Link (Web)","EAN/UPC","Weight","UNSPSC code","Product type code","Warranty"

假设你的桌子看起来像

CREATE TABLE supplierimport 
(
distributorid int, 
MPN varchar(32),
description varchar(100),
description2 varchar(100),
customers_price decimal(19,2),
home_stock int,
brand_name varchar(100),
delivery_date date,
item_group_number varchar(32),
item_group_name varchar(100),
product_link varchar(255),
picture_link varchar(255),
barcode varchar(32),
weight decimal(19,4),
UNSPSC varchar(32),
product_type_code varchar(32),
warranty varchar(32)
);

这将允许您成功加载数据

LOAD DATA LOCAL INFILE '/path/to/feed6.txt'
INTO TABLE supplierimport
    FIELDS TERMINATED BY ',' ENCLOSED BY '"'
    LINES TERMINATED BY '\n' -- or '\r\n' in your case
IGNORE 1 LINES
(MPN, @description, @description2, @customers_price, @home_stock, @brand_name, @delivery_date, 
 @item_group_number, @item_group_name, @product_link, @picture_link, @barcode, @weight, @UNSPSC, @product_type_code, @warranty)
SET distributorid = 546, 
    description       = NULLIF(@description, ''),
    description2      = NULLIF(@description2, ''),
    customers_price   = REPLACE(NULLIF(@customers_price), ',', ''), 
    home_stock        = NULLIF(@home_stock, ''), 
    brand_name        = NULLIF(@brand_name, ''), 
    delivery_date     = STR_TO_DATE(NULLIF(@delivery_date, ''), '%d/%m/%Y'), 
    item_group_number = NULLIF(@item_group_number, ''), 
    item_group_name   = NULLIF(@item_group_name, ''), 
    product_link      = NULLIF(@product_link, ''), 
    picture_link      = NULLIF(@picture_link, ''), 
    barcode           = NULLIF(@barcode, ''), 
    weight            = NULLIF(@weight, ''), 
    UNSPSC            = NULLIF(@UNSPSC, ''), 
    product_type_code = NULLIF(@product_type_code, ''), 
    warranty          = NULLIF(@warranty, '');
