加載數據infile所有跳過行

Question

我想在MySQL上使用加載數據infile功能，並且我的所有行都被跳過。我嘗試了其他線程的所有解決方案，但找不到解決我的問題的解決方案。我做錯了什麼，MySQL繼續跳過我的所有行？

查詢

LOAD DATA LOCAL INFILE 'C:\\Stockton\\DataFiles\\emaimport.csv' INTO TABLE moving_average 
FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n' 
(@col1, @col2, @col3) set ma_symbol=@col1,ma_date=@col2,ma15=@col3; 

表結構（僅插入到列MA15）數據的

CREATE TABLE `moving_average` (
    `ma_symbol` varchar(50) NOT NULL, 
    `ma_date` date NOT NULL, 
    `ma5` decimal(12,6) DEFAULT NULL, 
    `ma10` decimal(12,6) DEFAULT NULL, 
    `ma15` decimal(12,6) DEFAULT NULL, 
    `ma20` decimal(12,6) DEFAULT NULL, 
    `ma25` decimal(12,6) DEFAULT NULL, 
    `ma30` decimal(12,6) DEFAULT NULL, 
    `ma35` decimal(12,6) DEFAULT NULL, 
    `ma40` decimal(12,6) DEFAULT NULL, 
    `ma45` decimal(12,6) DEFAULT NULL, 
    `ma50` decimal(12,6) DEFAULT NULL, 
    `ma100` decimal(12,6) DEFAULT NULL, 
    `ma200` decimal(12,6) DEFAULT NULL, 
    PRIMARY KEY (`ma_symbol`,`ma_date`), 
    CONSTRAINT `fk_symbol_moving_average` FOREIGN KEY (`ma_symbol`) REFERENCES `company` (`symbol`) ON DELETE CASCADE ON UPDATE NO ACTION 
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Answer 1

你的查詢需要一個STR_TO_DATE函數爲date字段。

像這樣：

LOAD DATA LOCAL INFILE 'C:\\Stockton\\DataFiles\\emaimport.csv' INTO TABLE moving_average 
FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n' 
(@col1, @col2, @col3) set ma_symbol=@col1,ma_date=STR_TO_DATE(@col2,'%Y-%m-%d'),ma15=@col3;
