Question

我使用此查询但不显示列名

SELECT * FROM employeemaster INTO OUTFILE'c：/order-1.csv'FIELDS 终止于'，''由'\ n'终止的''';

Answer 1

使用以下查询：

SELECT empid as employeeid,sname as staffname FROM employeemaster INTO
OUTFILE 'c:/order.csv' FIELDS 
TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n';

Answer 2

有两种可能的解决方案：

简单的一个：自己对colum名称进行硬编码，并使用查询结果加入标题行：

SELECT 'Name_I_Want_For_Col1', 'Name_I_Want_For_Col1', 'Name_I_Want_For_Col1'
UNION ALL
SELECT ColName1, ColName2, ColName3
    FROM YourTable
    INTO OUTFILE '/path/outfile'

更直接（但更复杂）：从信息模式中获取列名称：

select GROUP_CONCAT(CONCAT("'",COLUMN_NAME,"'"))
from INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'my_table'
AND TABLE_SCHEMA = 'my_schema'
order BY ORDINAL_POSITION
UNION ALL
    SELECT ColName1, ColName2, ColName3
        FROM YourTable
        INTO OUTFILE '/path/outfile'

如何使用mysql中的列名将查询结果保存到excel文件中
