Как в VB.NET обратиться к user defined function на сервере ...

CREATE FUNCTION GetBranchesCount (@inn bigint)
RETURNS int AS  
BEGIN 
declare @res int

set @res=(select count(*) from Comp_Lst where inn=@inn)
return (@res-1)

END

dim cmd as new SqlDbCommand("select GetBranchesCount (@inn)", con)
cmd.Parammeters.Add("@inn", DbType.BigInt).Value = value
dim Res as Int32 = cmd.ExecuteScalar()

select dbo.GetBranchesCount(@inn)
