Question

我正在研究一个数据集的数据分析。 140,000条记录。我的数据集是 CSV文件。我正在尝试将数据导入MySQL工作台，但它只处理（添加）第一条记录，并发出1265行被截断的警告。像这样的东西

＆＃34; 0行受影响，1个警告：1265数据截断列＆＃39;位置＆＃39;在第1行记录：1删除：0跳过：1警告：1 ＆＃34;

我的实际查询是：

LOAD DATA LOCAL INFILE 'D:/PMK/SFPD_Incidents.csv' INTO TABLE incidents.incidents 
FIELDS TERMINATED BY ',' 
ENCLOSED BY '"' 
LINES TERMINATED BY '\r\n'
(IncidntNum, Category, Description, DayOfWeek, Date, Time, PdDistrict, Resolution, Address, X, Y, Location);

现在，当我为具有较少记录的小数据集运行相同的查询时，除了截断警告之外，它完全正常。

csv内容如下所示：

非常感谢任何帮助或修复。

Answer 1

您应该尝试验证/验证它。

我也遇到过大型CSV文件的问题，但大多数情况下这些值都存在问题。

因此可能存在破坏导入的价值。
