Question

以下MySql查询绝对没有任何内容

LOAD DATA
LOCAL INFILE 'path/to/file.csv'
REPLACE INTO
TABLE `db`.`table`
COLUMNS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(
    `id`,
    `name`
);

CSV文件如下：

"id","name"
"1","Lorem"
"2","Ipsum"
"3","Dolor"
"4","Sit"
"5","Amet"
"6","consectetur "
"7","adipisci"
"8","velit"
"9","sed"
"10","quia"

我检查了行分隔符，它是LF，文件编码是UTF-8。

我注意到如果我清空csv的第一行，或删除第一行的双引号，查询实际上会影响10行。

你知道为什么会这样吗？因为我宁愿我不必编辑第一行。

Answer 1

问题在于你的Escaped By '"'，因为第一次引用（“）遭遇，它被视为Escape。只要摆脱它，它就会起作用。

LOAD DATA
LOCAL INFILE 'path\\to\\file.csv'
REPLACE INTO
TABLE `db`.`table`
COLUMNS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(
    `id`,
    `name`
);

当第一行被“包围”时，MySQL LOAD DATA LOCAL INFILE不执行任何操作
