Hi all,

I have a big table, I want to select a part of them after an attribute, for example the attribute is "userId", I want select the records which userId = 5,6,9,20,...

I know, if the to selected userId list is not long, I can do it with "filter example" and set the "custom_filters" one by one. But if the userId list is huge, so I can not do it with "filter example"

For example, in the following table, I want select all the records, which userId = 1,3,9,20,...
userId time pr1 pr2
1 3-4 1 0
1 3-5 1 1
2 3-4 1 0
3 3-7 1 0
3 3-8 1 0
5 4-1 1 0
Do you know, how can I use rapidminer so deal with this problem?

    Hi,

    if you have a table with the wanted customer IDs, you can use a join to do this
