Query.jl join error - DataValues.DataValue{String} vs String


I got this error when using Query.jl to join two tables, where one table was read from CSV.jl and the other from ExcelReaders.jl.

I guess I could convert the columns somehow but wondering if there’s a better way to handle that… thanks in advance.

The keys in the join clause have different types, 
DataValues.DataValue{String} and String.


I worked around by “promoting” the value to DataValue type in the join condition.


Yeah, that is the best option right now. I’m enforcing that the values one joins on have to be of the same type right now. I might relax that at some point, but I need to think about it a bit more :slight_smile:
