CURRENT_DATE:返回当前日期。 EXTRACT(year/month/day FROM date):从日期中提取出指定的年、月或日。 ADD_MONTHS(date, months):返回增加指定月份数之后的日期。 LAST_DAY(date):返回指定日期所在月份的最后一天。 AGE(start_date, end_date):计算两个日期之间相差的天数。
DATE DSC支持迁移Teradata的SELECT语句中包含DATE FORMAT,使用TO_CHAR并以源格式显示日期。如果日期格式是一个表达式(例如:Start_Dt + 30)或者WHERE子句包含表达式(例如:WHERE Start_Dt > End_Dt),则不会执行此转换。 详情请参见转换类型为DATE(无DATE关键字)。
