Function questions about dates in Expression nodes

KNIME Analytics Platform
1

Hello, I have a question for the KNIME support team.

I am using KNIME AP version 5.4.2 and would like to utilize Expression nodes as Column Expression nodes have become legacy.

However, the functions related to date columns that were previously provided in Column Expreesion are not available in Expression.

As a simple example, even now(), which was available in Column Expression, is not available in Expression node, and all the functions in the picture below are not available.

I would like to know how I can use date related functions in Expression, including now() mentioned above. I am trying to refrain from using Column Expreesion (legacy) due to project circumstances.

Hey there,

right now date functions are not (yet) supported in Expressions nodes. At the KNIME Summit it was said that this is something that is coming in the not too distant future. So for now you can’t really move to Expressions if you use Date functions in Column Expressions.

Also: Column Expressions may have been named “legacy”, however this does not mean that it will be removed anytime soon. So you should be good to go to keep using them…
