LOAD DATA [LOW_PRIORITY | CONCURRENT] [LOCAL] INFILE ‘file_name.txt‘
    [REPLACE | IGNORE]
    INTO TABLE tbl_name
    [FIELDS
        [TERMINATED BY ‘string‘]
        [[OPTIONALLY] ENCLOSED BY ‘char‘]
        [ESCAPED BY ‘char‘ ]    ]
    [LINES
        [STARTING BY ‘string‘]
        [TERMINATED BY ‘string‘]    ]
    [IGNORE number LINES]
    [(col_name_or_user_var,...)]
    [SET col_name = expr,...)]

LOAD DATA INFILE语句用于高速地从一个文本文件中读取行，并装入一个表中。文件名称必须为一个文字字符串。

由character_set_database系统变量指示的字符集被用于解释文件中的信息。SET NAMES和character_set_client的设置不会影响对输入的解释。
典型的示例
LOAD DATA LOCAL INFILE ‘data.txt‘ INTO TABLE tbl_name 
FIELDS TERMINATED BY ‘,‘ 
OPTIONALLY ENCLOSED BY ‘"‘ 
LINES TERMINATED BY ‘\n‘
如果您只想载入一个表的部分列，则应指定一个列清单：
LOAD DATA LOCAL INFILE ‘persondata.txt‘ INTO TABLE persondata (col1,col2);
