mysql - I have a select query that gets me a single column as a result. Now I need to put all those column values in CSV format

Question

--------------------
- # - timesheet_id -
--------------------
- 1 -      1       -
--------------------
- 2 -      2       -
--------------------

Now the format required should be in "1,2" which is nothing but the values of timesheet_id. Somebody please help.

Answer 1

SELECT GROUP_CONCAT(timesheet_ID) as TimeList
FROM   tableName
INTO   OUTFILE '/tmp/timeIDList.csv'  -- file output path
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'

资源

• 将 MySQL 查询结果保存到文本或 CSV 文件中
• 直接从 MySQL 导出 CSV

Answer 2

在 mySQL 中，您可以使用 GROUP_CONCAT

SELECT GROUP_CONCAT(timesheet_id SEPARATOR ',') FROM table
