Table: Department
\n+-------------+---------+\n| Column Name | Type |\n+-------------+---------+\n| id | int |\n| revenue | int |\n| month | varchar |\n+-------------+---------+\nIn SQL,(id, month) is the primary key of this table.\nThe table has information about the revenue of each department per month.\nThe month has values in ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"].\n\n\n
\n\n
Reformat the table such that there is a department id column and a revenue column for each month.
\n\nReturn the result table in any order.
\n\nThe result format is in the following example.
\n\n\n
Example 1:
\n\n\nInput: \nDepartment table:\n+------+---------+-------+\n| id | revenue | month |\n+------+---------+-------+\n| 1 | 8000 | Jan |\n| 2 | 9000 | Jan |\n| 3 | 10000 | Feb |\n| 1 | 7000 | Feb |\n| 1 | 6000 | Mar |\n+------+---------+-------+\nOutput: \n+------+-------------+-------------+-------------+-----+-------------+\n| id | Jan_Revenue | Feb_Revenue | Mar_Revenue | ... | Dec_Revenue |\n+------+-------------+-------------+-------------+-----+-------------+\n| 1 | 8000 | 7000 | 6000 | ... | null |\n| 2 | 9000 | null | null | ... | null |\n| 3 | null | 10000 | null | ... | null |\n+------+-------------+-------------+-------------+-----+-------------+\nExplanation: The revenue from Apr to Dec is null.\nNote that the result table has 13 columns (1 for the department id + 12 for the months).\n\n", "translatedTitle": "重新格式化部门表", "translatedContent": "
表 Department：
\n+---------------+---------+\n| Column Name | Type |\n+---------------+---------+\n| id | int |\n| revenue | int |\n| month | varchar |\n+---------------+---------+\n在 SQL 中，(id, month) 是表的联合主键。\n这个表格有关于每个部门每月收入的信息。\n月份（month）可以取下列值 [\"Jan\",\"Feb\",\"Mar\",\"Apr\",\"May\",\"Jun\",\"Jul\",\"Aug\",\"Sep\",\"Oct\",\"Nov\",\"Dec\"]。\n\n\n
\n\n
重新格式化表格，使得 每个月 都有一个部门 id 列和一个收入列。
\n\n以 任意顺序 返回结果表。
\n\n结果格式如以下示例所示。
