I'm trying to create a view from a table in which I want to concatenate to columns to a new column. The concatenation part works fine when data "supports" calculations, i.e. no nulls. The data however is "infected" in two ways I have Null-values and I have blanks alongside with some real information. I concatenate via a CASE statement but I can't figure out how to take the 3 situations into account (nulls, blanks and data) and create one meaningfull column in my view.
The result should be
column1 + "-" if column2 is null or blank
column1 + "-" + column2 if column2 has meaningfull data
Both the involved columns are text (varchar).
If anyone has been in this situation before could you please provide som code that handles the situation.
