MySQL导入导出CSV

从CSV文件导入到MySQL:

LOAD DATA INFILE 'E:/file.csv'
INTO TABLE t1
CHARACTER SET gb2312
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'
(column1, @var1)
SET column2 = @var1/100;

从MySQL导出到CSV文件：

SELECT col1,col2,col3 FROM t1
INTO OUTFILE 'E:/file.csv'  
CHARACTER SET gb2312
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
LINES TERMINATED BY '\r\n';

csv文件第一行不得有标题行，否则要在LINES TERMINATED BY "\r\n"后面添加
IGNORE 1 LINES
