PHP mySQL LOAD LOCAL INFILE 导入正好一半？

Question

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，关于这个问题有两个问题：

1. 使用此语句是否正确； 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我的数据库中的cost 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； mysql load data local infile syntax issues with set fields 你可以看到我已经放了\r\n，但它仍然没有全部导入。

谁能帮忙。

谢谢

编辑：仅以逗号分隔的文本文件中的三行为例。这是从文件中按原样粘贴的，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, '');
