MySQL＆gt;为INTO OUTFILE的结果添加额外的字符

Question

对不起标题，想不到更好。

所以我的目标是将mysql中的json格式文本直接写入文件。我尝试过几个方法：

1）https://github.com/mysqludf/lib_mysqludf_json - 使用json_array函数

2）使用sql：

SELECT * INTO OUTFILE 'pathToFile' 
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"'
LINES 
    STARTING BY '['
    TERMINATED BY '],\n'
FROM Table

但两种情况都没有给我我想要的东西。

需要：

[
   ["1","2","3"],
   ["1","2","3"]
]

来自json_array函数：

["1","2","3"]
["1","2","3"]

来自sql：

["1","2","3"],
["1","2","3"],

任何想法如何更改sql语句以获得我想要的结果？或者可能以其他方式实现结果？
