Question

我有这样的表：

mysql> show create table final\G;
*************************** 1. row ***************************
       Table: final
Create Table: CREATE TABLE `final` (
  `id` int(4) NOT NULL AUTO_INCREMENT,
  `cdatetime` varchar(255) NOT NULL,
  `address` varchar(255) NOT NULL,
  `district` varchar(255) NOT NULL,
  `beat` varchar(255) NOT NULL,
  `grid` varchar(255) NOT NULL,
  `crimedescr` varchar(255) NOT NULL,
  `ucr_ncic_code` varchar(255) NOT NULL,
  `latitude` varchar(255) NOT NULL,
  `longitude` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1
1 row in set (0.00 sec)

我的csv文件看起来像这样：

cdatetime,address,district,beat,grid,crimedescr,ucr_ncic_code,latitude,longitude
1/1/06 0:00,3108 OCCIDENTAL DR,3,3C        ,1115,10851(A)VC TAKE VEH W/O OWNER,2404,38.55042047,-121.3914158
1/1/06 0:00,2082 EXPEDITION WAY,5,5A        ,1512,459 PC  BURGLARY RESIDENCE,2204,38.47350069,-121.4901858
1/1/06 0:00,4 PALEN CT,2,2A        ,212,10851(A)VC TAKE VEH W/O OWNER,2404,38.65784584,-121.4621009
1/1/06 0:00,22 BECKFORD CT,6,6C        ,1443,476 PC PASS FICTICIOUS CHECK,2501,38.50677377,-121.4269508

我想要做的是将CSV文件加载到table final中。问题是csv文件没有ID列，所以我想有可能以某种方式告诉mysql跳过列ID并将数据加载到其余列中，但必须使用ID 。理想情况下，它看起来像这样：

＆＃34; 1/1/06 0：00,3108 OCCIDENTAL DR，3,3C，1115,10851（A）VC TAKE VEH W / O OWNER，2404,38.55042047，-121.3914158＆＃34;加载到列中，mysql自动将1添加到列ID，然后＆＃34; 1/1/06 0：00,2082 EXPEDITION WAY，5,5A，1512,459 PC BURGLARY RESIDENCE，2204,38.47350069，-121.4901858＆＃ 34;得到加载和mysql添加2到ID列等等。

最近用户＆＃39;影子＆＃39;告诉我，我应该指定我要加载的列，所以我做了类似的事情：

load data infile '/SacramentocrimeJanuary2006.csv' INTO TABLE final (cdatetime, address, district, beat, grid, crimedescr, ucr_ncic_code, latitude, longitude);

Mysql返回：

ERROR 1261 (01000): Row 1 doesn't contain data for all columns

根据mysql加载数据infile手动字段分隔符不是＆＃34;，＆＃34;所以我试图通过添加FIELDS TERMINATED BY＆＃39;来改变它。在我的陈述结束但这打破了查询。这里的语法是什么？

Answer 1

我认为您需要添加enclosed by和ignore rows指令

LOAD DATA infile '/SacramentocrimeJanuary2006.csv' 
INTO TABLE final 
(cdatetime, address, district, beat, grid, crimedescr, ucr_ncic_code, latitude, longitude); 
FIELDS TERMINATED BY ',' 
ENCLOSED BY ''
IGNORE 1 ROWS;

Answer 2

Linux的：

LOAD DATA INFILE '/home/frank/try_this123.txt'
INTO TABLE final
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\n'
IGNORE 1 LINES
(cdatetime, address,district,beat,grid,crimedescr,ucr_ncic_code,latitude,longitude)
set id = NULL;

或Windows：

LOAD DATA INFILE 'c:\\nate\\try_this123.txt'
INTO TABLE final
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES
(cdatetime, address,district,beat,grid,crimedescr,ucr_ncic_code,latitude,longitude)
set id = NULL;

mysql> select * from final;

我没有任何封闭的分界，如单引号或双引号。问题是，当你的地址有逗号时会发生什么，并且它会因为一个转移问题而抛弃你的所有数据。

这就是为什么，理想情况下（读取：几乎绝对），除非您的数据是由您生成的，否则您需要包含在双引号中的数据，而且几乎过于简单，例如：

1,2,cat,14,8

因此，对于第三方系统，当无法控制数据的输入方式时，人们必须先编写ETL例程来清理数据，以便为导入数据做好准备-safe包装。

Answer 3

使用以下格式：

load data infile '/SacramentocrimeJanuary2006.csv' INTO TABLE final (cdatetime, address, district, beat, grid, crimedescr, ucr_ncic_code, latitude, longitude)
fields terminated by ',' 
lines terminated by '\r\n'
ignore 1 lines;

使用LOAD DATA INFILE跳过第一列
