[CQ-Contest] T-SQL Code to extract prefix from callsigns

[Martin LU5DX]

Hello guys,


I wonder if any of you have worked on extracting prefix information out 
of callsigns using T-SQL or any othe flavor of SQL language.

I know it may seem trivial, but it is not. There seem to be many 
possibilities involved to correctly extract the prefix of a callsign.

If any of you did enter that obscure world, I'd like to ask a few 
questions about it.


Thanks in advance,


Martin LU5DX
