从MySQL中的CSV文件导入数据

Question

我创建了一个名为 StatesandCities 的表，其中有3列： CountryCode （它是一个外键）， State 和 City < / em>，如下所示：

create table StatesandCities (CountryCode varchar(2), State varchar(20), city varchar(20),foreign key (CountryCode) references ListOfCountries (CountryCode));

我有一个包含所有值的.CSV文件：

CountryCode,State,City
IN,Karnataka,Bangalore
IN,Karnataka,Mysore
IN,Karnataka,Tumkur
IN,Maharashtra,Mumbai
IN,Maharashtra,Thane
IN,Maharashtra,Nasik
GB,Yorkshire,County Hill
GB,SouthWales,Murrey

这正是它在Excel工作表中的表现：

CountryCode State   City
IN  Karnataka   Bangalore
IN  Karnataka   Mysore
IN  Karnataka   Tumkur
IN  Maharashtra Mumbai
IN  Maharashtra Thane
IN  Maharashtra Nasik
GB  Yorkshire   County Hill
GB  SouthWales  Murrey

我使用此代码在MySQL 5.6命令行客户端中输入CSV文件：

LOAD DATA LOCAL INFILE 'H:/Statesncities.csv' INTO TABLE StatesandCities FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' ignore 1 lines (CountryCode, State, City);

正在输入值，但它们不是我需要的正确表格格式。而且如果数据值很长就会被削减。这一切都搞混了： 我试过改变屏幕大小，页面布局，似乎没什么用。

输出：

Answer 1

试试这个：

LOAD DATA LOCAL INFILE 'H:/countries.csv' INTO TABLE ListOfCountries
    FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
    LINES TERMINATED BY '\n'
    IGNORE 1 LINES (CountryName, CountryCode);

我正在使用IGNORE 1 LINES来跳过CSV标题行。我也可以选择FIELDS ENCLOSED BY。

您可以参考MySQL手册的LOAD DATA INFILE Syntax部分了解更多详情。

Answer 2

this should do it !!

BULK INSERT mycountry
        FROM 'C:\CSVmydata\country.csv'
        WITH
        (
        FIRSTROW = 2,
        FIELDTERMINATOR = ',',  --CSV field delimiter
        ROWTERMINATOR = '\n',   --Use to shift the control to next row
        ERRORFILE = 'C:\CSVmydata_error\countryErrorRows.csv',
        TABLOCK
        )
