Question

Please forgive me if this has been answered before.

I’m looking for some advice on how to build a pivot or cross tab query.

I have a table that looks likes this

Vessel    Date    Inspector
 A      02/05/10    Morris
 B      05/20/10   Clouseau
 A      07/25/10    Gadget

I need the results to be look like this

Vessel  Jan   Feb      Mar     April   May   June   July   Aug   Sept   Oct    Nov  Dec
  A           Morris                                Gadget
  B                                  Clouseau

Hopefully that makes sense. I’m hoping someone can give me some advice or help to get me started on this.

Thanks

Select Vessel
    , Min ( Case When Month([Date]) = 1 Then Inspector End ) As Jan
    , Min ( Case When Month([Date]) = 2 Then Inspector End ) As Feb
    , Min ( Case When Month([Date]) = 3 Then Inspector End ) As Mar
    ...
    , Min ( Case When Month([Date]) = 12 Then Inspector End ) As Dec
From Table
Group By Vessel

You have to statically declare the columns. It should be noted that this will only work for a single year. If what you are seeking is dynamic column (month) generation, then trying to do it in T-SQL is not the right approach as you can only do it with some fugly dynamic SQL. Instead, you should use a report generator or middle-tier component to build the result set.
