要显示给定周的员工花名册,首先需要确定员工的出勤记录和排班信息。这通常涉及到以下几个基础概念:
解决方法:使用编程语言中的日期处理库,如JavaScript的Date
对象,Python的datetime
模块等,计算出给定周的起始日期和结束日期。
function getWeekRange(year, weekNumber) {
const date = new Date(Date.UTC(year, 0, 1));
const day = date.getDay();
const weekStart = new Date(Date.UTC(year, 0, (weekNumber - 1) * 7 + 1 - day));
const weekEnd = new Date(weekStart.getTime() + 6 * 24 * 60 * 60 * 1000);
return { weekStart, weekEnd };
}
const { weekStart, weekEnd } = getWeekRange(2023, 35);
console.log(weekStart, weekEnd);
解决方法:使用SQL查询语句从数据库中筛选出给定日期范围内的员工出勤记录。
SELECT employee_id, name, attendance_date
FROM attendance_records
WHERE attendance_date BETWEEN '2023-08-21' AND '2023-08-27';
解决方法:将获取到的员工出勤记录按照部门或职位进行分组,并生成花名册。
function generateRoster(attendanceRecords) {
const roster = {};
attendanceRecords.forEach(record => {
if (!roster[record.department]) {
roster[record.department] = [];
}
roster[record.department].push(record.name);
});
return roster;
}
const attendanceRecords = [
{ employee_id: 1, name: 'Alice', department: 'HR', attendance_date: '2023-08-21' },
{ employee_id: 2, name: 'Bob', department: 'Engineering', attendance_date: '2023-08-22' },
// ... more records
];
const roster = generateRoster(attendanceRecords);
console.log(roster);
通过以上步骤,你可以有效地生成并显示给定周的员工花名册。
