Standard behaviour of column selection

Hi there,

We should discuss the standard behaviour of column selection:
At the moment we are somewhat not consistent in how we set the standard behaviour of our column selection. We really should discuss what's the right way here.
-> Replace and no column_name appendix
-> New table and no column_name appendix
-> Append .... etc

What do you prefer, what are your experiences?

Thank you for feedback,

Christian
