为方便用户使用脚本参数进行查询，数据湖计算DLC支持配置日期参数进行查询。
数据湖计算 DLC 标准日期格式为：yyyymmddhh24miss，通过${}命令将日期设为变量，变量分为日期、时间两个部分，结果为两部分之和。
日期部分，可以是任意日期格式或者系统预定义变量，如 yyyymmdd、yyyymm、yyyy-mm-dd、yy、dataDate。
日期变化部分，可以+/-N个周期，支持N/Nd、Nm、Nw、Nh、Nmi。兼容支持计算公式，如7*N、N/24。
举例
获取加减周期 | 方法 | 兼容格式 | 举例 |
后 N 年 | ${yyyymmdd+Ny} | - | - |
前 N 年 | ${yyyymmdd-Ny} | - | 前一年：${yyyymmdd-12m}：20190920 |
后 N 月 | - | ${yyyymmdd+Nm} | - |
前 N 月 | ${yyyymmdd-Nm} | $[add_months(yyyymmdd,-N)] | ${yyyymmdd-1m}：20200820 ${yyyymm}：202009 ${dataDate-1m}：20200820 |
后 N 周 | ${yyyymmdd+Nw} | ${yyyymmdd+7*N} | - |
前 N 周 | ${yyyymmdd-Nw} | ${yyyymmdd-7*N} | - |
后 N 天 | ${yyyymmdd+N/Nd} | - | - |
前 N 天 | ${yyyymmdd-N/Nd} | - | ${yyyymmdd-1}、${dataDate-1} |
后 N 小时 | ${yyyymmddhh24+Nh} | $[yyyymmddhh24+N/24] | - |
前 N 小时 | ${yyyymmddhh24-Nh} | $[yyyymmddhh24-N/24] | ${yyyymmddhh24-1h}：2020092014 ${dataDate-1h}： 2020092014 |
后 N 分钟 | ${yyyymmddhh24mi+Nmi} | $[yyyymmddhh24+N/24/60] | - |
前 N 分钟 | ${yyyymmddhh24mi-Nmi} | $[yyyymmddhh24-N/24/60] | ${yyyymmddhh24mi-10mi}、${dataDate-10mi} |
注意：
使用时需保证变量或变量中+/-前的格式符合日期标准格式，否则将无法被系统识别使用。
