MySQL 文件导入导出操作

1. 导入前设置

• 首先找到MySQL 数据库默认文件目录（例如：‘C:\ProgramData\MySQL\MySQL Server 8.0’）。如下图，我们建立的database都在*'Data’文件夹中，后续导出的文件默认也会在该这个文件夹的子文件夹里（相对应的database子文件夹）；‘Uploads’*文件夹是默认的导入文件夹。

• 默认文件夹使用起来往往不方便，修改默认文件夹过程中又会遇到各种ERROR。所以这里建议直接建一个默认文件夹的快捷方式。
  

2. 导入导出语句

• 导入语句

load data  [low_priority] [local] infile 'file_name txt' [replace | ignore]
into table tbl_name
[fields
	[terminated by't']
	[OPTIONALLY] enclosed by '']
	[escaped by'\' ]]
[lines terminated by'n']
[ignore number lines]
[(col_name,...)]

• 导出语句

SELECT *  [low_priority] [local] infile 'file_name txt' [replace | ignore]
FROM tbl_name
[fields
	[terminated by't']
	[OPTIONALLY] enclosed by '']
	[escaped by'\' ]]
[lines starting by 'string'
[lines terminated by'string']
