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…

is there a plan when will the date expression be launched?
I don’t think a firm date was committed to, but either at the summit or the 5.4 release talk the question came up and it was mentioned they are working on it.
I personally have my hopes up for 5.5, which is expected this summer.
Update:
I just checked a nightly built of 5.5 and voila: there are new Function groups “temporal” - that should be what you are after
