mysql导出select结果到文件
mysql -hxx -uxx -pxx -e “query statement” db > file
例如：
mysql -h127.0.0.1 -uroot -p000000 -e”select * from a” test > 1.txt
host ip user password query statement database filename
这样会输出列名信息，如果不想输出列名信息：
mysql -h127.0.0.1 -uroot -p000000 -N -e”select * from a” test > 1.txt
host ip user password query statement database filename
或
mysql -hxxx -uxx -pxx
select * from table into outfile ‘xxx.txt’;
例如：
mysql -h127.0.0.1 -uroot -p000000
select * from a into outfile ‘1.txt’;
两种方法效果一样的
第二种方式的mysql文档：
SELECT [select options go here] INTO {OUTFILE | DUMPFILE} filename
EXPORT_OPTIONS
FROM table_references [additional select options go here]
例如：
mysql -h127.0.0.1 -uroot -p000000
select * from a into outfile “1.txt” fields terminated by ‘\t’ lines terminated by ‘\r\n’
第一种方法和第二种方法的结合：使用 mysql -e执行导出到文件的sql语句
mysql -hxx -uxx -pxx -e “query statement” db
例如:
mysql -h127.0.0.1 -uroot -p000000 -e”select * from a into outfile ‘1.txt’ fields terminated by ‘,’ lines terminated by ‘\r\n'” test
如果不想输出列名信息：
mysql -h127.0.0.1 -uroot -p000000 -N -e”select * from a into outfile ‘1.txt’ fields terminated by ‘,’ lines terminated by ‘\r\n'” test
默认情况下， mysql -e导出的文件，列是用”\t”分隔，行是用”\r\n”分隔(dos)，行是用”\n”分隔(unix
追加一种方式：
select col002,col005,col004,col008 into outfile ‘e:/mysql/i0812.txt’ fields terminated by ‘|’ lines terminated by ‘\r\n’ from a where col003 in (select col001 from qdbm) order by col005;
