You can use this syntax to output your MySQL query results to a CSV file, for example:
SELECT blog_id, path, registered, last_updated
INTO OUTFILE '/tmp/test.csv'
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '\\'
LINES TERMINATED BY '\n'
WHERE path IN ('/105102/','/105095/','/103206/');
Note: It's better to output the file to /tmp directory because mysql user has permission to write there.
