I am currently working on processing Excel sheets using Apache POI. Now I am in a tricky situation where in I want a subset of data based on certain conditions.
In the sense that I have to get only the data which satisfies certain conditions, essentially a select query.
select distinct(category) from #Sheet where id < 10
I understand the above thing is possible in C#, but how do I achieve the same in Java using Apache POI.
Last time I worked with POI (about 1 year ago) there were no querying APIs.
However, if your query is really that simple, you should just scan the rows in Java and add the categories to a
Set<String>(orMap<String,Integer>if you want to count them as well).
