我正在将文件导入 MYSQL，如下所示：

LOAD DATA LOCAL INFILE 'C:\\Users\\Justin.Mathieu\\Documents\\data.csv' into table Ingredients
fields terminated by ','
optionally enclosed by '"' 
lines terminated by '\n'
(iVendor, iName, iOrderNumber, iCaseQty, iUnitSize, iDrainSize, iUnitSoldBy, iCaseCost, iVolumeConversion, iUnitLabel, iIngredients)

以及一些导入数据的样本：

VendorName,"Apple Whole Peeled Cored Grd A Fz",61318,1,\N,\N,\N,38.17,\N,\N,\N
VendorName,"Apples- Applesauce Sweetened",10738,6,\N,\N,-1,24,\N,\N,\N
VendorName,"Applesauce Unswtn Fancy",10676,6,106,\N,-1,23.97,\N,\N,"Apples, Water, Erythorbic Acid (To Maintain Color)"
VendorName,Apron 24"X42" White Reg Wt - Dispenser ,81463,1,\N,\N,\N,9.98,\N,\N,\N
VendorName,"Artichoke Heart 40-50Cnt Quartered,     Marintated",10722,6,88,\N,-1,71.46,\N,,"Artichoke Hearts, Vegetable Oil (Soya Or Sunflower), Water, Vinegar"
VendorName,"Artichoke Heart Crse Ct",77334,6,\N,55,\N,49.16,\N,\N,\N
VendorName,"Artichoke Heart Quarters",11804,6,\N,\N,-1,62.46,\N,\N,"Artichoke Hearts, Water, Salt And Citric Acid"
VendorName,"Artichoke Quarters Mixed Cuts",D6808,6,\N,\N,\N,60.26,\N,\N,\N
VendorName,"Bacon Bit Real Ref",56188,2,\N,\N,\N,51.22,\N,\N,\N
VendorName,"Barley Pearled Dry Us #1 Standard",33050,2,\N,\N,\N,21.38,\N,\N,\N

第一个问题是使用\N。在导入后查看我的数据库时，我没有得到空值，而是在 iIngredients 字段中得到“N”。

第二个问题是大多数行没有被导入，这是我得到的错误示例：

164 row(s) affected, 64 warning(s): 
1262 Row 3 was truncated; it contained more data than there were input columns 
1262 Row 5 was truncated; it contained more data than there were input columns 
1262 Row 9 was truncated; it contained more data than there were input columns 
1262 Row 10 was truncated; it contained more data than there were input columns 
1262 Row 11 was truncated; it contained more data than there were input columns 
1262 Row 12 was truncated; it contained more data than there were input columns 
Records: 164  Deleted: 0  Skipped: 0  Warnings: 94

我已经验证每一行都有任何可能包含逗号的数据，这些逗号被包裹在“”中。

任何想法可能会发生什么？

编辑：我能够解决 \N 问题，只需将 "" 用于字符串行，将 \N 用于非字符串行。

编辑 2：在被截断的行中，iIngredients 字段包含下一行的所有数据，就好像它没有检测到以“.

好吧，在闲逛了足够多之后，我想通了。

问题是，当我将文件转换为为空字段插入“/N”时（在 C# 中），我使用的是：

Write(rowData + Environment.NewLine);

显然 MySQL 真的不喜欢这样，所以我将其更改为：

Write(rowData + "\n");

这似乎工作得很好。

看起来行分隔符有问题，请检查它们是否在您的文件中为 '\n'，或者尝试在 LOAD DATA 命令中使用 '\r\n'。

另外，我看不出 \N 有什么问题，它按原样工作。

mysql 无法识别 '\n' 换行
