推荐答案
https://code.kx.com/q/ref/dotq/#qpf-partition-type 或其他.Q之一应为您完成此操作( https://code.kx.com/q/ref/card/#q ).尽管KX不一定建议使用.Q实用工具.
https://code.kx.com/q/ref/dotq/#qpf-partition-type or one of the other .Q's should do it for you (https://code.kx.com/q/ref/card/#q). Though KX don't necessarily recommend using .Q utilities.
另一种方法是检查是否存在变量"date"(如果日期已分区)，该变量列出了可用的分区日期.假设在此过程中没有创建随机的，不相关的全局日期"变量.
Another way would be to check for the existence of the variable "date" (if date-partitioned), which lists the available partitioned dates. Assuming there hasn't been a random unrelated global "date" variable created in the process.
