MySQL LOAD DATA LOCAL INFILE 当第一行被 "包围时什么都不做

Question

下面的 MySql 查询什么都不做

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"

我检查了换行符是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？因为我宁愿不必编辑第一行。

Answer 1

问题出在您的 Escaped By '"' 上，当第一个 quote(") 遇到时，它被视为 Escape。摆脱它，它会起作用。

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`
);
