WAMP - ySQL - DIsabling secure-file-priv

Question

我阅读了关于此的每一个帖子，但没有一个解决方案适用于我的情况。我做了一个函数将MySQL数据库表转储到CSV / TSV文件，继承代码：

function db_to_tsv($conn,$table) {

  $file_path = "C:/wamp64/tmp/{$table}_dump.tsv";

  $columns_array = $conn->query("SELECT * FROM $table LIMIT 1")->fetch();
  unset($columns_array['id']);
  $columns = implode(', ',array_keys($columns_array));

  $headers_array = array_map(
    function($value,$key) { return "'$key'"; },
    $columns_array,
    array_keys($columns_array)
  );

  $headers = implode(', ',$headers_array);

  $query = "(SELECT $headers)
    UNION 
    (SELECT $columns
    FROM $table
    INTO OUTFILE '$file_path'
    FIELDS ENCLOSED BY '\"' 
    TERMINATED BY '\n' 
    ESCAPED BY '\"'
    LINES TERMINATED BY '\r\n');
    ";

    $export = $conn->query($query);

}

所以SQL查询是这样的：

(SELECT $headers)
    UNION 
    (SELECT $columns
    FROM $table
    INTO OUTFILE 'C:/wamp64/tmp/{$table}_dump.csv'
    FIELDS ENCLOSED BY '\"' 
    TERMINATED BY '\n' 
    ESCAPED BY '\"'
    LINES TERMINATED BY '\r\n');
    ";

当我运行该函数时，我收到有关secure-file-priv被设置的错误。

当我运行SHOW VARIABLES LIKE "secure_file_priv"时，它会输出：

这就是我将输出文件指向C:/wamp64/tmp

的原因

显示出现的错误：

导入TSV文件时遇到了同样的问题：

LOAD DATA INFILE 'c:/wamp64/tmp/chebiId_inchi.tsv' 
INTO TABLE chebi_inchi  
FIELDS TERMINATED BY "\t" 
ENCLOSED BY '"' 
LINES TERMINATED BY '\n' 
IGNORE 1 ROWS
(chebi_id, inchi)
SET ID = NULL ; 

但是我通过在代码中添加LOCAL来解决这个问题，所以这很有效：

LOAD DATA LOCAL INFILE 'c:/wamp64/tmp/chebiId_inchi.tsv' 
INTO TABLE chebi_inchi  
FIELDS TERMINATED BY "\t" 
ENCLOSED BY '"' 
LINES TERMINATED BY '\n' 
IGNORE 1 ROWS
(chebi_id, inchi)
SET ID = NULL ; 

但是对于输出文件，没有LOCAL选项。我尝试将此行secure_file_priv=''添加到my.ini文件的顶部，但这会导致某种错误，我无法在那里打开MySQL控制台。

如何停用secure-file-priv设置？
