Question

我有一个＆＃34;加载数据＆＃34;执行得很好的命令，但我需要修改它以从CSV中删除大多数字段。我相信我已经把它正确地组合在一起，但是形成一些原因，MySQL说语法不正确。

LOAD DATA INFILE '/path/file' INTO TABLE cdr_records (@dummy,
@dummy,
@dummy,
@dummy,
dateTimeOrigination, 
@dummy,

@dummy) FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 2 LINES;

我明白了;

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 2 LIN' at line 104

Answer 1

应该是

LOAD DATA INFILE '/path/file' INTO TABLE cdr_records 
FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 2 LINES
(@dummy, ..., @dummy) ;

代替。首先是FIELD和LINES子句，然后是列的列表，而不是相反的方式。

LOAD DATA INFILE的语法是：

LOAD DATA [LOW_PRIORITY | CONCURRENT] [LOCAL] INFILE 'file_name'
    [REPLACE | IGNORE]
    INTO TABLE tbl_name
    [PARTITION (partition_name,...)]
    [CHARACTER SET charset_name]
    [{FIELDS | COLUMNS}
        [TERMINATED BY 'string']
        [[OPTIONALLY] ENCLOSED BY 'char']
        [ESCAPED BY 'char']
    ]
    [LINES
        [STARTING BY 'string']
        [TERMINATED BY 'string']
    ]
    [IGNORE number {LINES | ROWS}]
    [(col_name_or_user_var,...)]
    [SET col_name = expr,...]

Answer 2

首先放置终结器和其他选项

LOAD DATA INFILE '/path/file' INTO TABLE cdr_records
FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 2 LINES
(@dummy,
@dummy,
...

在MySQL语法错误上加载数据Infile
