Creating new ExampleSet by combining attributes from different blocks

Hello

 

I would like to know how can we append columns side by side coming from different operators into one. 

For instance, I have columns c1,c2 as output from one operator and c3,c4,c5 is from another operator.

 

I am looking for a operator which would give me all c1,c2,c3,c4,c5 together in one ExampleSet.

Length of all columns is same.

 

Thank you

Syed

    If there is a common ID field for both of those data sets, the easiest is to use the Join operator and join by ID.

    Hi,

    what you search for is called join. It works like Join in SQL. You might need to create an ID on both tables first.
