MySQL>；向输出文件的结果中添加额外字符

对不起，这个标题，想不出更好的了

因此，我的目标是将json格式的文本从mysql直接写入文件。我尝试了几种方法：

1） -使用json_数组函数

2） 使用sql：

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

但这两种情况都没有给我想要的

想要：

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

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

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

从json_数组函数中获取：

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

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

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

从sql获取：

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

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

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

有没有办法改变sql语句以得到我想要的结果？或者有没有其他方法可以达到这个效果？

这听起来很粗略。使用外部脚本不是这样做的吗？@tadman，现在我正在编辑我的结果文件，删除最后一个逗号并用其他作用域包装。但这并不酷，我想从mysql获得正确的json结果，没有其他解决方法mysql不打算在内部这样做。它只是一个数据库。在其周围使用薄脚本层通常是解决此类问题的方法。不要把它看作是一种变通方法，而要把它看作是如何工作的。
