Exercise 2 for KNIME User Training
- Concatenate data from two different sources
- Bring values from a reference table to the actual table using the Cell Replacer node
- Modify String values
- Join data from multiple tables
- Remove duplicates in the data
Hello,
I am going through this series of exercises and I have a question about activity I, part 1 of this exercise:
When concatenating the new and old web activity data, are the columns First(WebActivity) and First_WebActivity_ supposed to represent the same information? In that case, I assume one of them should be renamed before using the Concatenate node. Otherwise both tables have no intersection and both columns appear separated in the output table.
In the solution there is no renaming node, is that a mistake? Am I missing something?
