You can, but what if you have this type of data:
ColumnCode1  ColumnCode2  ColumnCode3   CodeCount
Code1          Code2         code3         3
Code1          Code2         Code4         2
Code3          Code1         Code4         12
Code7          Code9         Code1         21
>Can you use SELECT TOP 1 and then order it by codecount desc?
