通过'tr'管道(仅限Unix/Cygwin):

mysql <database> -e "<query here>" | tr '\t' ',' > data.csv

注意:这既不处理嵌入的逗号，也不处理嵌入的制表符。

Use:

mysql your_database -p < my_requests.sql | awk '{print $1","$2}' > out.csv

下面的Bash脚本适合我。它还可以选择获取所请求表的模式。

MySQL Workbench可以将记录集导出到CSV，而且它似乎可以很好地处理字段中的逗号。CSV可以在OpenOffice Calc中打开。

这个答案使用Python和一个流行的第三方库，PyMySQL。我添加它是因为Python的csv库足够强大，可以正确处理许多不同风格的.csv，而且没有其他答案使用Python代码与数据库交互。

import contextlib
import csv
import datetime
import os

# https://github.com/PyMySQL/PyMySQL
import pymysql

SQL_QUERY = """
SELECT * FROM my_table WHERE my_attribute = 'my_attribute';
"""

# embedding passwords in code gets nasty when you use version control
# the environment is not much better, but this is an example
# https://stackoverflow.com/questions/12461484
SQL_USER = os.environ['SQL_USER']
SQL_PASS = os.environ['SQL_PASS']

connection = pymysql.connect(host='localhost',
                             user=SQL_USER,
                             password=SQL_PASS,
                             db='dbname')

with contextlib.closing(connection):
    with connection.cursor() as cursor:
        cursor.execute(SQL_QUERY)
        # Hope you have enough memory :)
        results = cursor.fetchall()

output_file = 'my_query-{}.csv'.format(datetime.datetime.today().strftime('%Y-%m-%d'))
with open(output_file, 'w', newline='') as csvfile:
    # http://stackoverflow.com/a/17725590/2958070 about lineterminator
    csv_writer = csv.writer(csvfile, lineterminator='\n')
    csv_writer.writerows(results)

这救了我几次。它又快又有效!

——批 打印结果，使用制表符作为列分隔符，每行在 新行。 ——raw禁用字符转义(\n， \t， \0和\)

例子:

mysql -udemo_user -p -h127.0.0.1 --port=3306 \
   --default-character-set=utf8mb4 --database=demo_database \
   --batch --raw < /tmp/demo_sql_query.sql > /tmp/demo_csv_export.tsv

为了完整起见，您可以转换为CSV(但要小心，因为制表符可能位于字段值内部—例如，文本字段)
