mysql - 错误 1062 (23000) : Duplicate entry though entries are not duplicate

Question

表定义:

CREATE TABLE PositionalDataNGS ( Date DATE, Time TIME(3) , X FLOAT(5), Y FLOAT(5), D FLOAT(5) , V FLOAT(5),  OnField BOOL, GameID_GSIS INT, TeamID INT, PlayerID_GSIS CHAR(10), PRIMARY KEY(Time) );

这将创建所需的表格，我需要用以下条目填充它:

    Data, Time, X, Y, D, V, OnFeild, GameID, TeamID,  PlayerID_GSIS  
 2015-11-15 ,17:56:45.300 ,  93.32,  8.6,  4.57,  0.45 , true,   2015111500  , 5110  , 22-0026189 
 2015-11-15 ,17:56:45.400 ,  93.77,  8.48,  4.55,  0.47 , true,   2015111500  , 5110  , 02-0022289 
 2015-11-15 ,17:56:45.500 ,  94.23,  8.36,  4.53,  0.47 , true,   2015111500  , 5110  , 03-0026179 
 2015-11-15 ,17:56:45.600 ,  94.67,  8.23,  4.51,  0.46 , true,   2015111500  , 5110  , 30-0026180 

显然时间不重复，但是当尝试将 csv 表填充到数据库时:

LOAD DATA INFILE "/PositionalDataNGS_2.csv" INTO TABLE PositionalDataNGS COLUMNS TERMINATED BY ',' LINES TERMINATED BY '\n' IGNORE 1 LINES;

我收到此错误: 错误 1062 (23000):键“PRIMARY”的重复条目“17:56:45.300”

这是 MySQL 5.6.28，因此它应该能够处理几分之一秒的时间。谢谢!

我无法重现该问题。文件 PositionalDataNGS_2.csv 中没有重复值？
