极客教程MySQL 如何将数据导出到CSV文件并将列标题作为第一行？
需要使用UNION语句来添加列值。可以通过以下示例进行演示 –
**示例 **
在此示例中，将从student_info中导出数据到CSV文件中。CSV文件的第一行将是列名称。
mysql>(SELECT 'id', 'Name', 'Address', 'Subject')UNION(SELECT id, Name, Address, Subject From student_info INTO OUTFILE 'C:/mysql/bin/mysql-files/student_25.CSV'
FIELDS ENCLOSED BY '"' TERMINATED BY ';' ESCAPED BY '"' LINES TERMINATED BY '\r
');
Query OK, 7 rows affected (0.04 sec)
执行上述查询后，MySQL将创建名为Student_25.CSV的文件，其中包含以下值 –
id; "Name"; "Address"; "Subject"
101; "YashPal"; "Amritsar"; "History"
105; "Gaurav"; "Chandigarh"; "Literature"
125; "Raman"; "Shimla"; "Computers"
130; "Ram"; "Jhansi"; "Computers"
132; "Shyam"; "Chandigarh"; "Economics"
133; "Mohan"; "Delhi"; "Computers"
