```sql SELECT date_format(last_day(date_column), 'yyyy-MM-dd') as end_of_month FROM table_name; 1. 2. 3. 在上面的代码中,我们首先使用`last_day()`函数获取日期列`date_column`所在月的最后一天日期,然后使用`date_format()`函数将日期格式化为`yyyy-MM-dd`的形式,最终得到每个月的月末日期。
下面是代码示例: SELECTCASEWHENmonth(current_date())>1THENyear(current_date())ELSEyear(current_date())-1ENDASlast_year,CASEWHENmonth(current_date())>1THENmonth(current_date())-1ELSE12ENDASlast_month; 1. 2. 3. 4. 5. 6. 7. 8. 上述代码将返回上月的年份和月份,例如对于当前日期为2022-...
