我有一个选择查询,结果我得到一个列.现在我需要将所有列值以CSV格式放置

Question

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

现在所需的格式应该是"1,2",这只是timesheet_id的值.有人请帮忙.

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'
