Hi
I wanted a function to find the greatest of a list of String values passed in.
I want to invoke it as Select greatest('Abcd','Efgh','Zxy','EAD') .It should return Zxy.The number of parameters is variable.
So I wrote a very simple CLR function (Vs2008) and tried to deploy it.
See below

public partial class UserDefinedFunctions
{
[Microsoft.SqlServer.Server.SqlFunction]
public static SqlString Greatest(params SqlString[] p)
{
SqlString max=p[0];
foreach (string s in p)
max = s.CompareTo(max) > 0 ? s : max;

return max;

}
};

But when I try to compile or deploy it I get the following error
Cannot find data type SqlString[].

Is it possible to satisfy my requirement using SQL CLR ?

Have you tried String[] instead of SqlString[]
