当我执行以下查询时，它可以工作：
SELECT 'INNODB_OS_LOG_WRITTEN','QUESTIONS' INTO OUTFILE 'D:/orders.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n';
但是，当我从 Windows 命令提示符或使用以下命令的批处理文件中调用此查询时，
"%MBIN%\mysql.exe" -u"%MUSER%" -p"%MPASS%" -h "%MHOST%" -e "SELECT 'INNODB_OS_LOG_WRITTEN','QUESTIONS' INTO OUTFILE 'D:/orders.csv ' 由 ' 终止的字段，' 由 '"' 以 '\n' 终止的行；"
它没有运行。
粘贴下面我运行上述命令时发生的情况。

%MHOST%" -e "SELECT 'INNODB_OS_LOG_WRITTEN','QUESTIONS' INTO OUTFILE 'foldrname/
orders.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n';"

--auto-rehash Enable automatic rehashing. One doesn't need to use
'rehash' to get table and field completion, but startup
and reconnecting may take a longer time. Disable with
--disable-auto-rehash.
(Defaults to on; use --skip-auto-rehash to disable.)
-A, --no-auto-rehash
No automatic rehashing. One has to use 'rehash' to get
table and field completion. This gives a quicker start of
mysql and disables rehashing on reconnect.
--auto-vertical-output
Automatically switch to vertical output mode if the
result is wider than the terminal width.
-B, --batch Don't use history file. Disable interactive behavior.
(Enables --silent.)
我注意到的另一件事是，当我运行以下命令时：
"%MBIN%\mysql.exe" -u"%MUSER%" -p"%MPASS%" -h "%MHOST%" -e "SELECT 'INNODB_OS_LOG_WRITTEN','QUESTIONS';"
从命令提示符或批处理文件中，它正在执行（注意 - 我删除了 csv 导出）。
因此，从批处理文件（或 Windows 命令提示符）执行查询的组合似乎无法正常工作。
任何机构都可以帮助解决这个问题。
