Hi all
I am trying to change the column type. it should be Boolean Value, but some other values come in chaining the type to “?”. So I would need to / want to change the type to “String”, however, I don’t know how. I used the node “column expressions”, but don’t know hot to configure it. They way I did configure it, gives me an error
“No converter for column type ‘Non-Native [DataValue, Nominal]’ of column ‘Match Found’ exists.”
Hi @Cal_Steffen , can you show what your input data table looks like as I have not been able to reproduce that error message with Column Expressions even by forcing the table to contain an “unknown” data type. Which version of KNIME are you using?
Did you try the Column Auto Typecast node? That would be my first move.
Hi all
The Auto Typecast is solving my problem - Thanks so much.
Sharing the input data is tricky, since it is my credit card statements 
I have tried to create a training data set to share, but I have not gotten to the point where I get the output at the same place with the same issues. At this point it created more work to create a training data set then using the Auto Type Cast and be done with it.
Thank you for your support!
Hello @Cal_Steffen,
Yes, I agree with @iCFO.
You can visit the KNIME Community Hub and easily drag and drop from there. Additionally, I’ve attached a link for your reference.
